LED lamp purchase depends on price/performance

Not long after New Day, an engineering customers we spoke with, the National Day after he had finished, he told a large enterprise, energy-saving lighting company, during the National Day to buy a 5000 led street light wholesale, the eve of National Day how the finished work. and after the National Day holiday is done, the company was started, the staff in the workshop to see the workshop With the newly installed LED fluorescent tube, look at the current market of all is how the legend of LED energy-saving fluorescent tube, the brightness is good Therefore, employees are eagerly anticipating to see what had happened.
       Surprising is that when employees into the shop, turn on the light when fresh mood has not been past the shop to exterminate the few pieces of that time because the company is doing electronic products factory, so employees are aware of electronic products in the batch will produce some failures also normal, so the production line staff on a few pieces of information out of the LED fluorescent tube and not too concerned about starting up their own normal work routine.

       Yet at the time of day in the past, when the production line of LED fluorescent tube began to exterminate a team of over 30%. In this case the person in charge of the production line, began to feel there are some things wrong, so be responsible to the factory who responded to the situation. the factory manager also raised the issue of the engineering company.

       In fact, the real reason is that this enterprise, in doing energy saving, because usually see the market average price of a led street lighting fixture (1.2 m 18WLED lamp) at around 40 dollars, companies had also found a lot of home LED fluorescent tube manufacturer, resulting in this price are about little difference in the choice of the number of enterprises, the customer has selected a price of around 17 yuan, a manufacturer, said their home was consulting LED Tube use two years have caused no problems. so when customers were directly in their home purchase.

       Because the lamp cheap when buying LED fluorescent tube manufacturers had to say good year warranty, but when a problem occurs, the manufacturers really show such a cheap price, but also insurance for one year if they are no profits, may also a loss. so then customers will find us. let us repair, try to see if I can get them to reduce the losses. current production damaged LED Tube products are also sent to Shenzhen Technology Co., Ltd. Keen Lai road.

2013-2015 Global LED lighting market by region change and prediction

From the observation of the world's major lighting market, developed countries due to the LED lighting development process earlier, in 2015 the proportion of total global market size will remain high, according to industry body estimates the United States, Europe, Japan and the district are more than 5 billion US dollars, the total proportion will reach 55%, which, in Europe, the United States reached 19.2 percent share of all, 18.8 percent, surpassing Japan, 17%; worth noting that Japan 2015 will be only 13.2% annual growth rate, lower than the United States and Europe 33.1%, 38%, mainly due to its LED lighting penetration will reach 78.6% due.
LED lighting market
In contrast, the population more into led street light with solar panel is also more active in emerging markets with growth potential, where the mainland due to government policy incentives under the LED industry, LED lighting market annual growth performance is superior to developed countries in 2015 will reach 46.5% the market size will be $ 4.57 billion; high global population in several Indian cities facelift for public lighting LED light source driven by the estimated market size of $ 820 million, accounting for 2.7% of global; previously was also optimistic about the Russian market, because of the recent overall economic prospects are more doubts under the influence, in 2015 the proportion of total global LED lighting will be comparable to 2014, was 4.1%.

LED lighting product line development process point of view, whether developed or emerging market countries with higher, outdoor lighting, commercial lighting penetration, followed by indoor home lighting will then be more different in Japan that will lead business according to household lighting, outdoor lighting 100% penetration. LED lighting prices, per capita income is associated with the district, which, in emerging markets, for example, in addition to the market price of the preferred outside Russia, China, India, led street lighting Manufacturer and energy-saving lamps appear fairly priced even lower case, so cost control and maintain a reasonable profit business has become the focus of the lighting industry.

Analysis of the present situation and development trend of modern lighting

In recent years, the classical, neo-classical, romantic garden, modern minimalist style, and many other categories, modern minimalist lighting with its closely pulse of the times, the fusion of fashion features, led high bay light supplier for many consumers. In the town lights are dozens of modern minimalist lighting brands among its research and design lighting Michelangelo topped advantage, customers receive a high degree of recognition.

Appear lighting

In the seventies and eighties in China, there is no "Lighting" word, the house is the allocation of national or self-help housing, the normal areas of access to electricity has been quite good, many backward places kerosene lamps, lighting equipment and other ancient lantern. Nineties, with the wave of reform and opening up the coast, the country's economy started its rapid development, the real estate market, a group of people get rich first led to the original home decoration market, "Lighting" As the market demand appeared.

Lighting exist due to construction

Lighting exist due to construction. Light is not just light, it is the architectural design, home design in part, if it is separated from the building, it loses its value and vitality. Lighting services in home life, from the perspective of the development history of the global industrial design there is a large gap between China and the world of lighting design developed countries. Lighting design is part of the industrial design of a classification, such as cars, small appliances are all areas of industrial design. Industrial design, which has a term, as people interact with machines that harmony between man and machine and exchange experience. For example, automobile, people sit in comfort, ease of operation of the driving and so on. Lighting design is the same, excellent lighting design products to make a difference with the lamp of emotion, rather than isolating each lost contact, and a concept which is the Michelangelo lighting always adhere to - that is the home lighting and home function, home arts connect up to become a whole person and harmonious living environment. These ideas thanks to daily communication with foreign architects and industrial designers peers.

Overseas, European designers and other developed countries, especially the architects, their overall architectural design, interior design, and even furniture design, including lighting design is by the architect or the leadership of the team as a overall done, so as to ensure the integrity and architectural design perfection.

In China, the lighting design is currently only passively serve a part of the building design. Division and the operational level in the market, many areas are associated with the architectural design unilaterally cut into a number of sectors, in fact, from an artistic level in terms of structure, they are serving a whole architectural art and culture at home.

The development of modern style lighting

Lighting is an art and architectural style, and is closely related to the trend of the times. In the classical, neo-classical, romantic garden, and many other modern minimalist style categories, modern minimalist style lighting its pace with times, the fusion of fashion features, lighting for many consumers. Modern minimalist lighting market in recent years has been widely sought after, mainly because the current mainstream consumers have turned 80 after 90 young people, their freedom of thought, economic independence, the pursuit of individuality and fashion sense. In addition, the modern real estate generally tend to modeling, the appearance of simple architecture Founder, story shorter, suitable for modern decoration style and the use of modern lighting.

However, because of the trend of modern lights, determine the product life cycle is generally shorter, so modern lamp design and development faster than other styles, or be thrown pace of the market. This requires the development of lighting designers with the times, designers not only to improve the aesthetic individual areas of expertise, but also absorb inspiration from other product areas, including the use of materials, combinations of structure and aesthetic elements, and so on.

In addition to aesthetics, market, modern lighting features, technology is developing with the tide of the times, such as before with a thick patch package, but now there back packaging technology, led high bay light for sale can be thinner and more delicate. This gives lighting designers to reduce the number of constraints on the volume of material, have more space to play. The rapid development of LED light source technology, to provide a piece of art lighting design can soar in the sky.

From the "China Lighting Capital" to "world lights"

Advanced stage of development to everything from low-level, there is a gradual process from quantitative to qualitative change. The core competitiveness of modern lighting design is first, followed by the production efficiency. If the product design is not competitive, it is impossible to have a competitive brand. The majority of our lighting products currently regarded as qualified products only from excellent products top products have a long distance. From the brand connotation, China currently has no real lighting brand brand in the world. Compared to other mature industries, such as luxury goods, clothing, automobile industry, China's lighting industry is still very young. And most of the same industry, the lighting industry started in counterfeit products, what products to sell on the market do what the product, industry plagiarism rife. Now, many manufacturers began prescient take the brand's line, which is a qualitative change in the process.

Do the brand which has a very important principle that must begin with the concept of level boss. Only when the corporate brand leader with a high degree of brand awareness, to insist on going down the road of brand building. Leader and the corporate culture there is a consensus, then it may make such a good product. Secondly, personnel training, including design professionals, marketing personnel, production technology talent gap is huge. Urgently improve the lighting industry talent training mechanism, this will need to be perfect from the perspective of the company, the state system.

Chinese lighting brand to the world of the road, the "Chinese lights are" into "the world lights are" long and winding road, which requires aspiring "lights" and one after another to achieve this great goal.

The Myth of LED energy-saving lamps

LED lighting is one of the world's focus has been to promote the project and, therefore, has been gradually accepted by consumers, it is worth noting that the average consumer for this new led street lights price there are some errors in the understanding of:

A misunderstanding, a few W's LED bulb can replace incandescent few W's.

Because usually they talk wattage incandescent lumens without speaking, over time they affect consumer buying habits of the lamp. LED technology with incandescent lamps, the LED light effect is still evolving, so are not representative of its wattage lumens. Some manufacturers are given on the packaging is similar to "40W incandescent replacement product," the label to help consumers buy.

Jane's words, and that they can not be represented by W LED bulb flux.

Myth, LED greater the power, brightness, brighter.

LED's generally believed that the greater the power, the greater is its lumen flux, representing the brightness will be more bright, in fact, this is a wrong perception, different power led street light wholesale lumen output (lm), the higher, the more saving, like on: 7W and 8W LED bulbs compared if higher lumen output 7W 8W, then, 7W light actually more energy efficient than 8W in.

Capital chain rupture Lamp Enterprise controlling costs key

According to the survey, this year, the number of enterprises above designated size was significantly reduced lighting. Indeed, lighting companies now under the overall situation in the case of the downturn, companies are developing into a more awkward situation into. But behind the sluggish industry environment, their own impediments can not be ignored, want to reverse the inverse Bureau, lighting companies started from their own is the best solution.

Industry downturn trend, companies control costs as key

In recent years, under the regulation of the property market policies, led high bay lighting wholesale in recent years, have a nice day struggling, although this year the purchase of housing to relax, the central bank cut interest rates and other positive news frequent lighting industry, but is now overcrowded home market, the competition intensified, profit margins are narrowing, many SMEs have difficulties to survive. Especially in the "cash is king" today, lack of funds, rising costs, benefits and other issues eventually led to the decline of the fact that funding strand breaks, but also makes the development of lighting business into a corner.

In the face of these difficulties and obstacles, capital chain rupture will lead to small and medium business will be more difficult lighting or even bankruptcy. So, how to guard against financial risks and maintain financial security, improve capital efficiency, has become the focus of the lighting industry issues. The ultimate goal of any power and lighting business development is to profit when the market sales business with competitors or less, cost control has become the key to gaining a competitive advantage. Therefore, reducing costs is the only way to survive the ice-breaking lighting business. Especially low-value-added, the lighting industry slow return on investment, cost control is particularly important.

Control costs, lighting companies need to start from the details

Lighting companies from raw material sourcing to product design, production, quality control, inventory, to product sales, cost control must be run through every link. And cost control every aspect must proceed from the subtle, corporate losses are often a lot of money caused by the details. Therefore, control costs from the details of the start, so that companies have to pay attention to the details of each employee, in order to prevent the occurrence of some adverse events, and truly implement cost control.

In addition, scientific and reasonable manner "cutting" is also one of the key cost control. Trivialize, simplify complicated things, scientific control, moderate control, a short time may not have much effect, but the good habits, to control costs will grow bigger role. led high bay light for sale should have done very meticulous in every aspect, intentions, such attention to detail habits must also be gradually integrated into the corporate culture and ethos of them. Only the details start to implement cost savings for all.

Since the development of the lighting industry, wind and rain along the way business is actually easy. On this difficult path, although the external environment is not optimistic, but as long as the lighting business from their own, will be able to alleviate the difficulties to some extent, ultimately leading to the success of the other side.

Analysis of LED lighting dealer

Lighting industry from the current point of view, whether it is the capital of the dealer or cities, counties dealers are feeling the changes in the industry and increasing the operating pressure. In the communication process, "confidence" and "direction" is the business most mentioned words.
In these businesses, whether it is after the line earlier 50,60,70, with annual sales of over billion of "old world", or products with annual sales of several million dollars and even tens of millions, to join in the near 80,90 after the "New Horizons", they are groping for their own development, are working hard to build confidence for future operations.

In most businesses among the older generation, they worked hard for 10-20 years before the resulting capital to flow from a simple model to lighting large wholesale shop operator. There are also some businesses "duties" involved in car leasing, guarantees, real estate and other industries.
Especially in the era of led street light wholesale, they all have to take a cautious investment approach, both upstream and downstream of the brand of choice or the distribution of cooperation are more "conservative."

The new entrants to the industry soon 80,90 "rookie" who, by the store rent increases, staff salaries rising product falling profits and other factors, the overall operating pressure is too large. But these young businesses have a son, "unyielding" momentum, whether it is the ability to accept or learning ability are quite strong, the ability to adjust the business direction, looking for their own business on the road.

In recent years, the development of e-commerce, especially this year, "double-October", dazzling lighting brands have to hand over the transcripts, some lighting brands even a single day online sales reached nearly billion, so many businesses exclaimed: this is another warning industry traditional channels.
However, the electricity supplier fiery, dealers can be described as love-hate relationship:
Love is that they can also participate, was "a piece"; hate is the electricity supplier to seize his own business in the local market, and most companies are reluctant to share the electricity supplier and dealer profits.
Therefore, dealers Acting corporate brand is doing e-commerce, e-commerce is very concerned about how to do it.

We are currently in the exchange led street lighting fixture with the business, the dealers have said, "You can try." Many businessmen said that the future development of the industry for the traditional channels as important, but how will the traditional channels and emerging e-commerce combined to achieve the harmonious development of both.
Of course, businesses are constantly thinking about the progress of the channel, the traditional channel not only to the traditional business, but want to "service business" transformation.
Future development of the industry, is inseparable from the terminal channel services, you know, there is no service sales practices is in the "bullying."

Diversification of LED lighting display screen time has come

With the display of new research and development, as well as new market demand and breakthrough application environment, the domestic led street light with solar panel enterprises are facing new market opportunities.
     From the current level of competition in the domestic LED electronic display industry, the competition in the domestic industry is still in its early product competition level, the competition is mainly reflected in key indicators: aspects of price, quality, delivery time, after-sales service.
 
     Needless to say, the government's policy is the LED industry's most far-reaching impact on the external factors, but it led to the output and benefited companies are very limited. Enterprises are to take root, to secure their position, the most effective way, is also the most reliable self.

     "Concentrate on promotion segment market share, while increasing investment in technological innovation and scientific research and development, adhere to the construction of 'channels first brand', seeking long-term and sustainable development of the domestic LED display enterprises are effective way. "think Shanghai electronic Engineering Ltd. (hereinafter referred to as the" Shanghai think twice "), deputy general manager, said in bloom.

     As blooming said that under the policy to promote and multiple factors such as capital markets, competitive landscape display industry has begun to show the range of products also diversified development.

     From the perspective of product types, LED display showing the trend more apparent. In the large-screen market, LED full color display has become a mainstream product, but to the first door panel as the representative of the small-screen market is still dominated by a single color products. But as technology advances and costs decline as a single-color product last line of defense of the first door panel market, will soon be broken, full-color LED display.

     As a leading LED application companies, Shanghai think twice developed proprietary LED displays and LED lighting products, LED applications, a comprehensive display of top-class technical strength. Especially in the full-color display business, but the industry has set a lofty position.

     On the scale of production, the company has led street lighting Manufacturer, electronics assembly, welding, testing and other production lines, all kinds of photovoltaic performance testing equipment, material properties testing equipment of various types of devices, packaging, plug-ins, solid crystal, welding, placement and other specialized equipment hundred Taiwan. Has of 100,000 / year and 300,000 LED display units / year production capacity of LED lights.

     In marketing and brand building, the Shanghai think 11 consecutive annual sales of more than billion, with an average growth rate of over 30%.

     At the same time, for eight consecutive years of customer satisfaction survey, "think" brand of LED products, customer satisfaction rate of 98.9%, at home and abroad to establish a prestigious national brand image.

     In addition, the Shanghai Times Square in New York think twice offered to create a Chinese LED full color LED display sign in staging the world's leading enterprise product of its kind, was "SIGN" as: the world's second largest LED manufacturers.

Nine factors determine the price of LED lamps

Continuous development of lighting industry, LED lighting and traditional lighting constant competition. Production of LED and LED lighting manufacturers numerous, different manufacturers use different quality LED lamps LED is caused by a different reason. Due to increasingly fierce price war, appearance, structure, function almost the same product, there are two to three times the price difference, many users get a moment to be faint mind, I do not know come from the spread, generally do not produce led high bay lighting wholesale LED light tube are difficult to distinguish, not to mention consumers.

So they have a good selection of LED sources of production, or testing equipment has improved LED LED lighting factory would be better, so buy LED lighting products will be more secure.

We take a look at what factors caused the price difference LED lamps:

1, Brightness

LED brightness is different, different prices.

2, antistatic ability

Antistatic ability of LED, long life, and therefore higher prices. The LED is usually static than 700V can be used for LED lighting.

3, the wavelength

Same wavelength LED, and color, such as requiring the same color, the price is high. No LED spectral separation device manufacturers is difficult to produce pure colors.

4, leakage current

LED is one-way conductive light, if there is reverse current is called leakage, leakage current is large LED, short life, low prices.

5, light angle

Different uses LED light emission angle is not the same. Special light-emitting angle, and higher prices. If all diffusion angle, higher prices.

6, life

Different quality is the key to life, life is determined by the light fades. Light decay, long life, long life, high price.

7, LED chips

LED luminous body for the chip, different chips, prices vary widely. Japan, the United States more expensive chips, Taiwan factory and China's domestic manufacturers of LED chip prices lower than Japan and the US.

8, the chip size

The size of the chip to side expressed great quality LED chip is better than small chips. Chip size is proportional to the price of the same.

9, colloids

LED ordinary colloidal generally epoxy resin, plus a UV LED and fire agents more expensive, high-quality outdoor LED lighting should be UV and fire.

LED lighting market is still part of the outlaws, cheating suppliers, suppliers of material fraud finished products to finished abnormally low prices in exchange for cash. There are a few led high bay light supplier manufacturers to deceive unrealistic promises dealers and users, and then continue to change the firm or person in charge of trick to shirk responsibility, therefore, when consumers buy must pay attention to these details.

What is the difference between soft LED screen display and LED display

Soft LED screen display by LED dot matrix, through red, green and blue light blinking beads to display text, images, animation, video, content can be replaced at any time, the various parts of the components are modular structure of the display device. Ingenious structure designed to achieve the horizontal and vertical bending installation, even more complex installation requirements, can achieve perfection; usually by the display module, the control system and power supply system. Its features are as follows:

     Can adapt to the complex installation environment: Can horizontal and vertical bending installation, even complex installation environment can present the perfect picture;

     Easy maintenance: the use of unique led street lighting Manufacturer structure, the replacement of a single light bar can simply unscrew three nuts, you can use the site for quick maintenance;

     High degree of protection, without fear of inclement weather rain: The third-party professional organizations detection: M Series soft curtain of protection up to IP65, without fear of inclement weather rain, ease of use in outdoor environments;

     Light (12 kg / m2): weighs only 12 kg / sq m, a person can easily install and transport products, saving you the cost of the product installation time and costs;

     Through: The pixel bar design, the product up to 60% transparent rate, low drag, up 12 anti-wind, you can be assured of the product in windy weather;

     Thin: the thickness of only 11mm, small footprint, saving you space and transport packing stage space for your use and transportation has brought great convenience;

     Professional-grade connectors, patch fast, safe and reliable: the choice of professional-grade connectors aviation plug, safe and reliable, with no less than a high degree of protection IP65, quick disassembly;

     High-quality power supply, stable and reliable: the selection of high-quality power supply, to further ensure the stable operation of the product for a long time.

     LED display common characteristics:

     1, high brightness: Outdoor led street light wholesale is greater than 8000mcd / m2, is currently the only large-scale display terminal can be used in outdoor weather; indoor LED display brightness is greater than 2000md / m2;

     2, long life: LED life of up to 100,000 hours (ten years) or more, which generally refers to the design parameters of life, brightness dark can be considered;

     3, the viewing angle: indoor viewing angle greater than 160 degrees, outdoor viewing angle greater than 120 degrees. The size of angle depends on the shape LED light-emitting diodes;

     4, the screen area is big or small, as small as less than one square meter, big is up to hundreds of thousands of square meters;

     5, easy and computer interface, support for software-rich;

     6, the common large display terminal contrast.

     By analyzing these characteristics, we may come to a soft LED screen LED display screen than ordinary advantages: light, thin, transparent, convenient installation and maintenance, flexible elastic, more energy and so on. With the advancement of LED display technology future, there will be more, better, more energy-efficient LED display.

LED key performance indicators

(A) LED colors: led high bay light price is a very important indicator, is related to each LED lighting products must indicate the current LED's colors are red, green, blue, cyan, yellow, white, warm white, amber and so on. We design and orders at the time of this argument is that it must not be forgotten (especially beginners). Because of different colors, the relevant parameters have changed a lot.

(B) LED current: LED forward limit (IF) in the current multi-20MA, and LED light failure can not be greater than the current IF / 3, about 15MA and 18MA. LED luminous intensity only in a certain range is proportional to the IF, when IF> 20MA, the brightness enhancement has been unable to come out with the eye points. Therefore, LED's operating current general election around 17-19MA reasonable. Front against a common low-power LED LED (0.04-0.08W) between terms, except for some Piranha LED (some are rated at about 40MA value).

In addition to the continuous development of technology, high-power LED is also emerging as 0.5W LED (IF = 150MA), 1W LED (IF = 350MA), 3W LED (IF = 750MA) there are other more specifications, I mixed one introduced, you can check it yourself LED manual.

(C) voltage LED: The LED is commonly referred to as forward voltage, that is positive for positive power supply of the LED, the negative power supply is negative. Voltage relationship with color, red, yellow, green voltage is between 1.8-2.4v. White, blue, green voltage is between 3.0-3.6v, where I want to be reminded that there will be some differences with the group to produce the LED voltage, according to the subject provided by the manufacturer, when the outside temperature rises, VF will decline.

(Four) LED reverse voltage VRm: allows to increase the maximum reverse voltage. Exceed the values, the light-emitting diode may be breakdown.

(E) LED color temperature: absolute temperature K to indicate, i.e. a standard black body heated, the temperature rises to a certain extent, starting from the dark red color - light red - orange - white - blue, gradually changing, a light source and a blackbody color is the same, the absolute temperature of the blackbody at the time referred to the color temperature of the light source.

In fact due to the correlated color temperature of the black body radiation is near the light source color, the light source color performance evaluation value, not a precise color contrast, so with the same color temperature value of the second light source, the light color appearance may still slight differences. Color led high bay light for sale can not understand the source of the object's color capabilities, or how to reproduce the color of an object under the light source.
       (Vi) emission intensity (I, Intensity): Unit Candela, that cd. Defines a light source in a given flux direction unit solid angle for the light emitted in the direction of the (fat) light intensity (degree), the emission intensity for the point light source in terms of, or compare with the irradiation distance compared to the size of the luminous body small occasions. This amount is to show the ability to converge the luminous body in space emitted. We can say that the luminous intensity is to describe the light in the end how "bright", because it is a common description of the optical power and convergence capabilities. The larger the light emission intensity, the brighter the light source looks, while under the same conditions after the irradiation by the object, the brighter the light sources, therefore, described earlier flashlight are using this parameter.

LED is now also used to describe this unit, such as a LED is 15,000, the unit is mcd, 1000mcd = 1cd, therefore 15000mcd is 15cd. The reason for LED cents cd (mcd) rather than directly with the cd to represent, because before the first LED is dark, such as 1984's standard 5mm LED luminous intensity was 0.005cd, so it expressed by mcd.

Luminous intensity is represented by "brightness" of the disadvantage is that if the die exactly the same two LED, a good degree of converging the emission intensity is high. Therefore, users should not only focus on high I value when buying LED, depends on irradiation angle. Many LED high I was not to improve their emission efficiency to achieve, but the lens is extended irradiation angle narrowing realize that although useful LED flashlight, but the viewing angle is also limited. Further, the same die LED, 5mm in diameter I value more than twice as large 3mm, but only 1/4 of the diameter of 10mm, the larger the convergence characteristic because the lens the better.

The eight guess of LED lighting industry in 2015

2014 for the LED lighting business is a challenge harvest year, cross-border Gangster "invasion" LED industry, the rise of the electricity supplier O2O, the rise of intelligent lighting concepts ...... these are not without side lead the LED business day not the same adjustment for 2014 will soon be over, waving to us in 2015, then in the new year LED industry will be how to develop it? The following are the eight led high bay lighting wholesale guess!
1, the new Chinese lamps popular: With the rise of China's comprehensive strength of a big country, big country to catch up with Europe and America, every continent in the world is bound to set off a "China Dream" Renaissance style storm, with today's technology and materials, "high imitation "China wind style lamps will be sought after by consumers around the world!

2, intelligent lighting began to rise: intense competition LED lamps, LED advantages of regulated more and more obvious, the major manufacturers in order to stand out from the competition, no flame on a simple price, while technically improve their competitive intelligence and capabilities of intelligent lighting will be a high-profile hit the market.

3, the pan-home lighting gratitude boom: the harsh competition in the industry as home lighting, home lighting gratitude of the whole old, have smooth lighting products proposed pan-home lighting gratitude began to rise, a variety of styles, categories of home lighting also appear in a store have been common.

4, a single product alliances: With the industry brand development, centralized orders. More and more manufacturers alliance hold together the advantages of a single product development.

5, lighting Eclectic popular: led high bay light manufacturers diversified development more widely, from the process, materials, styles, colors and other topics is not a single element, lighting mix and match elements will gradually get consumers!

6, selling software status highlights: With the strong development of the electricity supplier, OTO and other sales model, similar to the lamp with the software and data analysis software sales will become a standard tool for lighting industry.

7, bio-light a star: With the rise of the health industry, bio-lantern entering a golden period.

8, engineering lighting market rebound: big market downturn will get warmer, the government will make the appropriate regulation, project lighting market will get warmer.

2015 smart LED lighting industry trends forecast

This year, LED lighting technology advances, terminal prices continue to decline, and continuously improve product cost, intelligent lighting, O2O and other new technologies, new applications, new concept models continue to rise. LED is like a marvelous treasure, colorful but unlimited reverie. This year, LED lighting applications, what new changes occur? Intelligent lighting heat wave, how to better promote intelligent buy led high bay lamps integrated into people's lives? Government and universities to work closely together to promote the development of the LED lighting industry? Around these topics, especially interviewed (Old Town) Semiconductor Lighting Technology Research Center director Chen Jiansheng Sun Yat-sen, to share his insights on the development trend of LED lighting applications, as well as their feelings and experiences in terms of research cooperation.
First, from the pursuit of light efficiency to the pursuit of light quality
In recent years, low-carbon economy, energy saving and environmental protection concept is increasingly understood by the public, the energetic efforts of state and government at all levels, LED lighting industry to flourish. According to industry-related statistics, in 2013, the overall size of China's LED lighting industry reached 257.6 billion yuan, an increase of 34% compared with 2012, 2014 LED lighting penetration rate in 2013 will be 8% -10% increase to 32.7%. In 陈建胜 seems that this year the development of led street light wholesale industry has an obvious feature that has gradually from the simple pursuit of efficiency, cost-effective to pay attention to the direction of light quality, light and healthy lighting environment development experience.
"A few years ago, LED lighting products, changes in technology and other indicators light efficiency is very fast, usually a new product out, manufacturers play concept is light efficiency has improved much. Now, the luminous efficiency LED light source has reached 150LM / W , 170LM / W, the rate of change in the light effects and other aspects have been slowed down. and when you see the light show will find Asia exhibition, light quality, light environment is increasingly being taken seriously. this shows that LED lighting has come a simple pursuit of luminous efficiency price growth stage, and into the rapid popularization and application stage. "Chen Jiansheng, director said. According to Chen, this year, LED lighting standards continue to improve, the light source module continues to accelerate the development and application, and consumers are increasingly concerned about the quality of light, a variety of factors, human needs, safety and stability, intelligent lighting, healthy lighting is showing a very broad application prospects.
Second, intelligent lighting should be integrated with intelligent building organic
Intelligent LED lighting is an industry term red hot this year, many forward-thinking companies have also begun to actively intelligent lighting layout. This year, Philips introduced LED bulbs ITES Hue, Fun fans millet economy also introduced Yeelight smart bulb. In this regard, Chen Jiansheng that, LED has the property of microelectronics, semiconductors, LED intelligent lighting is considered to be an important growth point increase in value-added semiconductor lighting, it involves many technical fields, focused sensor and control technology, information and communication technology, not only is an effective way of saving lighting, but also the organic integration with the smart home, smart building.
"In fact, as part of the intelligent building, smart lighting has a certain basis, but the adjustable electronic properties of LED light, color, and so on can be controlled can dig out more meaning." According to Chen introduced in foreign countries, intelligent lighting more often and overall architectural integration in one, and the user is also concerned not just lighting. Into the LED, allowing innovative applications of intelligent lighting has endless possibilities, from the current point of view, the original is applied to the traditional lighting of the DALI (Digital Addressable Lighting Interface) protocol has been extended to also apply to LED lighting, in recent years, Sun Yat-sen (Old Town) semiconductor Lighting technology Research Center has also invested a lot of manpower, material and time-based research and promotion DALI protocol indoor intelligent lighting control system, and actively assist the relevant departments to vigorously promote the standard construction of intelligent LED lighting.
Third, intelligent lighting should focus on humanity and Big Data
"Now, the growing popularity of smart phones, many consumers do not need specialized training on the flexibility to manipulate a variety of programs on the phone, the game, which has accumulated a user for the promotion of intelligent lighting." In 陈建胜 view, widely smartphones applications for intelligent lighting laid the user base, meanwhile, intelligent lighting and it is not a pure system integration, only to be controlled by setting the parameters for the lights and so on. "The real intelligent lighting is humane, personalized, there is more interaction between people and lights and innovation." Chen Jiansheng said.
To allow us to better understand the concept of intelligent lighting, Chen gave a very vivid example. "We have worked with lighting Zhongshan Medical University joint research and treatment of mental illness, so that there is the treatment of choice in patients with mental disorders space lighting atmosphere (such as color, brightness, etc.) in order to understand the patient's preference for light and using light environments patient counseling and treatment. at the same time, the patient's every choice, will be stored in the smart system to provide support for large data research. Therefore, intelligent lighting must have big massive data base relationship between the man and the lights very subtle, but the ultimate aim is to make intelligent lighting lighting for the people, and create a more healthy, comfortable, humane light environment. "
Fourth, the intelligent lighting applications should strengthen subdivision
In terms of promotion and application of intelligent lighting, Chen believes that due to cost constraints and other aspects of the application of intelligent lighting is still relatively limited, and the future of intelligent lighting segments can be combined to study. "Light is an electromagnetic wave, it can carry very heterogeneous information, use of these lights is now more information is entertainment. In fact, we can make lighting better for some special populations, special needs in segments conduct services. for example, each lamp lights, there is a determined position, the use of light for navigation, positioning, may be worth for the average person is not high, but the visually impaired can be directed through the lighting of road. "
In addition, the intelligent lighting lighting in healthy animals lighting, plant lighting and many other fields have a very broad room for innovation, and cross-border trend nowadays for the lighting industry is an actuator, is a manifestation of LED lighting great vitality. The future development of intelligent lighting will also be reflected in the trend of the following three directions: First, the pursuit of pragmatism, that the lights in the final analysis is the desire to serve; the second is the pursuit of subdivision application; the third is the quality of light and healthy environment.

The encyclopedia Led application and classification

According to shape classification, wafer and chip is generally divided into square pieces. Where the wafer is relatively low-speed performance is not stable enough, I generally do not use led street lighting fixture; size square piece generally measured, such as 12mil (1mil = 0.0254 mm2). In general, the same brand of chips, chip size, the higher the brightness. LED lamp beads I most often used, usually in red and yellow 9 ~ 12mil, white, blue, green, generally in the 12 ~ 14mil, which is the most common chip market, if a larger chip, brightness Although it is possible to improve a lot, but a substantial increase in chip prices, which is the reason why the large chip size rarely used.
LED color tips:

Is determined by its different color LED chips of different wavelengths determined, for example, red light chip wavelength is generally 620 ~ 630nm (nanometers), green chip is generally wavelength 527nm, the wavelength of the blue chip generally is 470nm, yellow chips generally wavelength is 585nm, white LED is blue chip, but in the blue chip with the right amount of phosphor to emit a white light.

LED classification:

Size divided by power: can be divided into low-power, high-power (0.5W over the industry in general to be called high power lamp lights)

Divided by shape: can be divided into DIP and SMD.

Straw hat LED: they can be subdivided into the cap size F3 (cap diameter of 3mm), F5 (cap diameter of 5mm); or by the shape of the lamp is broken boundless, thin edge, thick edge, round; press transparent or not transparent cap can be divided into mist.

Piranha LED: lamp of the same size can be divided into F3, F5, according to the shape of the lamp into the round (ie, the most common piranha lights), flat head (this is very special shaped head, the luminous angle close to 180 degrees, generally used in situations require astigmatism).

Low-power SMD LED: Dimensions can be divided according to 0805,1206,3020,3528,5050 or 5060 (5050 and 5060 the difference is very small, the naked eye is difficult to distinguish, for unprofessional customers can call with his habit).

High-power LED: Press the power to distinguish between general, a common 0.5W, 1W, 3W, 5W, 8W ......

LED chips (chip) Number of common sense:

With an LED lamp, the most common is the use of only one chip, but in special cases can use two was even up to four chips, such as: a hat light may be one to two chips (in view of its relatively small size, heat dissipation is not easily lead to unstable performance, generally using only one or two chips); a piranha lights can be used one, two, three, four chips, I was the most commonly used one and two chips; you can use a light patch 3528 , two, three chips (our usual one, two chips), SMD 5050/5060 generally use three chips. Special note: When the three chip SMD lamps, there are two cases:

1. Three identical color chips

2. Three chips are red, green and blue, that is, we often say that the RGB lights

LED light-emitting angle (viewing angle) of common sense:

The most common line LED emitting angle is 120 degrees, 45 degrees can do special, or 15 degrees.

LED voltage (voltage) of common sense:

A single low-power LED lamps, different colors, which require different voltages. Red / Yellow: generally 1.8 to 2.1 volts, white / green / blue: generally 3.0 to 3.6 volts. 1W high power lamp voltage requirements the same as above. www.6366msc.com

LED current (current) common sense:

1. Low-power led street lighting Manufacturer (including plug-in or SMD), allowing the current through each chip is generally no higher than 20 mA; allow current through each of the two-chip lamp generally no higher than 40 mA; with rationale for each three-chip light not higher than 60 mA.

2. High power LED, I often used is 1W, which allows a maximum current of 150 mA through.

LED brightness (intensity) of common sense:

1. Candlelight, international candle, candela (candela) of the definition

At 101,325 Newton per square meter standard atmospheric pressure, an area equal to 1/60 cm absolute "black body" (i.e., able to absorb all of the external light reflected from an object and there is no ideal), pure platinum (Pt) solidification temperature (about 2042K eligible 1769 ℃), the luminous intensity in the vertical direction is 1 candela. And, candlelight, international candle, candela three concepts are different, not the same. In terms of quantity, equal to 60 candela 58.8 international candles, lights a candle hefner international candle equals 0.885 or 0.919 candela.

2. luminous intensity and brightness

Referred to as light emission intensity is strong, international unit is candela (cd) abbreviated cd. Lcd refers to luminous flux emitted from the light source in the specified direction unit solid angle. The radiation source is uniform, the light intensity I = F / Ω, Ω is the solid angle, in units of steradian (sr), F is the luminous flux, in units of lumens, for a point light source by I = F / 4. Brightness is the brightness of the light-emitting surface, is the ratio of the light emitting surface of the luminescent intensity in the specified direction and the direction perpendicular to the light emitting surface of the specified area of the unit is candela / square meter. For a diffuse scattering surface, despite the different intensity and luminous flux in all directions, but the brightness is equal in all directions. The TV screen is similar to such a diffuse scattering surface, so images are viewed from all directions, have the same sense of brightness.

Long life may make LED lighting industry into "grave"

"My family has a LED lamp installed in 2010, not bad, but also with a sense of eight or ten years." One consumer said half-jokingly, that he wanted to change only the lights can not find an excuse.

Long-life LED's for the majority of consumers is undoubtedly a big "gospel." However, for LED companies are concerned, the question is, has the industry put forward, "LED lights are too durable, not bad, so go the demand come from? How many re-purchase rate in the end?"
      At present, LED tubes, led street light with solar panel nominal service life varies, there are 15,000 hours, 25,000 hours vary, should use the three hours per day basis, the service life of 15,000 hours of lamp can be used 13.7 years (using lamp life of 25,000 hours can be used 22.8 years), should use 10 hours a day in accordance with the terms, the service life of 15,000 hours of lamp can use 4.1 years (25,000 hours of lamp life of 6.85 years can be used). Regardless of all enterprises producing various kinds of LED lamps if there is problem on the subject of virtual life this argument, many industry insiders indeed recognized that "long life" had the advantage of this now seems to be the LED's "weakness."

"This fear is justified." BYD lighting sales director Xiao Zhiyong said that life is too long will lead to smaller markets. Today, more than 20,000 companies in the market, in the end could only hundreds. "But then again, when we choose to do LED, when everyone's mind in addition to optimistic about the market outlook, there is part of the reason is because it is green."

"This is indeed a problem." Have focused on the package, and now gradually transformed lion photoelectric lighting applications Bo Peng said the vice president, should the LED lamps using the best components, then the life expectancy of 30,000 hours are possible a. "Long life is its selling point, but the long-life cause its complex exchange rate, this is a contradiction lies."

Peng also mentioned that now the issue has emerged in Japan. LED lights to replace the bulk of the Japanese market really hot for a while. "Quality requirements of the Japanese market is particularly high for a long time will have to be changed in a number of new requirements, in fact, I think the Japanese shipments of LED lighting has been shrinking."

"Basically for one, one less potential market is smaller." Industry analyst who asked not to be named, deeply worried, the market is so big cake, eat a piece, such as eight or ten years down to eat a piece of perhaps companies have already starved to death.

LEDinside senior analyst, said Wang Fei, long life, or will become the industry's epitaph. Each sale of a group of lighting means that the market has been cut a cake. "This may also confirmed from the side of the LED why so many recent corporate failures."

However, there are some on the market is always the optimist. South China University of Technology, Professor Wen Shang Sheng believes that if the LED as an electronic product to do, give it more personalized and innovation, "Think of it as art, a pursuit, repeat purchase rate is no problem."

Shares ROCKETS Jiawei, vice president believes that the industry can go to focus on some new technology. "Includes plant lighting, automotive lighting, visible light communication, which is the largest market for LED applications. I believe that our large market applications, LED market, there will be many new areas await excavation."

"I think it is positioning itself to do it, the whole market capacity is great, (take the street it) you see China's roads have been widened, do not worry." Philips Lumileds Asia Pacific Marketing Director, said Zhou Xuejun.

But then again, if the LED lamp life whether, as advocated by the industry so high? "Now, because of the pressure of competition in the market, most companies do not do so will be the life of the lamp is high, not to mention 30,000 hours, 10,000 hours can persist probably are few." Peng believes that circulate on the market now products are not the best quality products, it is precisely in terms of performance and price and market matching products. "That is why, long-life impact of the complex exchange rate for the Chinese market might not behave so obvious. On the other hand, LED current penetration rate is not high, the market is very broad."

"If the domestic market has emerged this fear, I think it is actually caused by oversupply in the domestic market, the products sold, instead of things that are not very durable." Zhejiang and Hui Lighting Technology Co., Ltd. Deputy Similarly, President Jian-Hua Ding believes that the current market does not actually have any real large quantities of long-life products.

However, led street light wholesale said industrial really need a plan of elimination period, the market needs to have a long life and critical point, the change was more conducive to the upgrading of products and technologies. "For the LED, the industry is also discussed, we think it would be more appropriate for 2-5 years, part of the construction class, professional class lighting can be higher."

Even if all the people in the industry for long-life LED will impact market exchange rate of the complex showed varying degrees of fear, but one thing is certain. As Wang Fei said, "Although the LED industry is putting pressure on long-term growth potential, but this is precisely what a real contribution to energy saving LED can make."...

LED lighting industry: the channel is king and content is king?

Channel is king and content is king per line per sector will be the topic of debate, of course, if both are prepared not occur naturally fierce arguments do not like the results of the scene. However, many enterprises are often very difficult and limited ability to make difficult both channels and content complete. In the led high bay light supplier, is also facing this problem, many entrepreneurs LED channel is king in the end is still a problem with the content is king broken brain.

American Marketing gurus Philip Kotler had done to define marketing channels, simply put, is the marketing channels for goods and services transfer process from the producer to the consumer the specific channel or path. We can not think, is the essence of marketing channels for the king is king, the manner in which allow consumers willing to buy your product is the focus of marketing channels.

Observation of the market, we can be found in the short term, the channels for the development of enterprises can play a key role, even a decisive role. Especially in this age of advanced Internet, the rapid rise of electricity providers, the network of sales channels for the development of the LED business has a huge role, so many LED companies pursue market channels for the king's purpose.

Only allow enterprises to quickly develop in the short term will focus entirely on the marketing channels. However, the rapid development of LED enterprises can still build quality of led high bay light for sale is excellent, the service is based on sound. Just marketing companies to sell their products to consumers in the hands of a way, the final evaluation is based on the consumer product itself

. The market will eventually LED brand beloved by consumers almost all high-quality products and better services to stabilize the market share, rather than to emphasize effective channel model to help companies achieve long-term steady development.

full resolution of LED support knowledge

There are different types of LED lamp beads different types, in fact, different LED caused by stent type according to different applications. Specific categories are: in-line stand, patch bracket, power bracket, flat bracket and cob holder. LED stent due to the need electrical and thermal conductivity, it will be used as the substrate metal. At the same time, some areas need to insulate, which requires use of engineering plastics. Therefore, the general LED support is through the metal stamping and then formed by injection molding. LED as a light emitting diode, the need for metal surface by plating silver as a good light reflecting material, it is generally LED for silver plating surface treatment.
  2835LED bracket
Scaffolds using various power led street light with solar panel is not the same, low-power general use PPA, the power generally use PCT, there are some high-power uses EMC materials. All plastic materials are water-absorbent, so LED lamp production process of the bracket needs to be dehumidified baking.
Processing plating layer is the key point of the stent, the coating thickness and quality of the relationship between the flux, welding performance behind. A good selection of LED actually the first condition is to choose a good stand, the current market there are some pressing iron substrate, and then plating, injection form, which is relatively poor quality. The power is still better to use copper plating layer needs to be controlled in the 80U '' around better, but there are a lot of manufacturers only require plating to 40U '' can be, a thin coating stents to control the welding, can easily lead to false welding. Now stand there most powerful ceramic substrate, if it is to figure out the composition of ceramic materials ceramic coating these key points. Appearing on the market power of the COB lamp beads, copper plating is generally used after the injection formation, CITIZEN of COB lamp beads stent is used to form a laminated aluminum, aluminum CITIZEN course there is a certain selection criteria, the upper BT board material PCB material is employed, the intermediate adhesive is critical.
The following pictures are of various types of LED bracket:
5050 Crystal six foot three stents
  Integrated high-power stand
High-power integrated bracket, using copper aim is to strengthen the future of thermal conductivity, lower thermal resistance.

led street lighting Manufacturer are some in-line stand not explain the current lighting much.
Currently filament bulb shape and candle lights compare to live, then they stand and what look like? See the following figure:
  Filament support
The sapphire using metal strips wrap that's it! This is why the shape of the stent filament breakage easily one of the reasons.
Highlights bracket selection: a metallic material type. 2, plating quality (thickness, plating methods). 3, the plastic injection molding material.

LED lamps export rankings between 2011 and 2014

At present, China's export market, the overall concentration has increased, is increasing rapidly in emerging markets, the export structure more balanced. Three quarters of 2014, most of China's exports are tube light fixtures, followed by bulb, light bar, spotlights, one of the highest clear tube lights exporting countries are the United States, China, Hong Kong and Japan, the highest export bulb countries are the United States and Japan, countries with the highest light bar / regions in Germany and the United States. Separate from the tube lights, exports highest Guangdong, Zhejiang and Jiangsu provinces.
Our led high bay light supplier mainstream products are bulb, tube lights and light bar lights, spotlights and interior lights, and outdoor floodlight and garden lights also exports a large amount of products. But in contrast to recent years, the interior lighting is still occupy the top few export products.

Industry agency data show that three quarters of 2014, China's LED lighting exports excluded 43.7% of the type is unknown, the clear portion of the lamp type with tube lights, accounting for 13.2% of total exports, total exports jumped over Bulbs the first. Followed by bulb, accounting for 10.65%,. Followed by light bar lights, accounting for 6.79%. Spotlight overall exports accounted for 5.8%.

But it is worth noting that although the growth rate of these types of lamps remained around 50%, but its proportion in the narrow, three quarters of 2014, several major lighting (bulb, tube lights, light bar and spotlights) the proportion of the sum fell 13.2 percentage points compared with 2013. Three quarters of 2014, the growth rate reached nearly aquarium lights 426%; flat light growth rate reached 312%, but its exports is still less; secondly Grille grew 213%, continuing rapid growth in 2013.
Lighting export rankings

Industry agency data show that the first half of 2014 to Europe's fastest growing led high bay light price products: travel lights, explosion proof lights, plant lights, the average growth rate reached 200%, these high-value-added in the last two quarters fixtures the proportion has been rising in the first half of 2014, the proportion of the several types of lighting upgrade to 13.4%. Compared with the same period last year improved 6.77 percentage.

The price mystery of the COB led light

In the current market cob light, high-end products can be sold for more than 1 per watt price range of ordinary products distributed in about 5-6 hair, while some of Zhongshan COB light source can even reach 3-4 hairs "limit price" market situation so mixed, but we as consumers in choosing when to buy lighting products, must want to know the cost of the spread where?
The survey interviewed by reporters in common COB lighting products, with their proportion of the share price of the sort order: 1 chip; 2, gold wire; 3, glue; 4 bracket. In addition, the substrate material is accounted for part of the price of COB light source can not be ignored.

Articles in this issue because of limited space, to which a higher proportion of temporary chip and the industry to discuss higher frequency gold wire material factors determine the cost of the production process, do a simple discussion. As for the glue, brackets and board, etc., follow-up reports will be filled. Hopes to be able to initiate the series of articles, and readers together to uncover the mystery spreads COB light source.

Although the led street light wholesale after years of development, but still can not change the fact that - the chip is still accounted for the bulk of the price of light. Reporter survey showed that the current chip accounted for over half the cost of the light source, even nearly 70 individual. Meanwhile, with the domestic chip quality generally improved, it has been able to replace imported chips in some areas.

"At present, our production is domestic chip-based lighting products, but in some special series also used the Taiwan-based manufacturer of chips imported chips and domestic chip compared to the price will be higher, generally more expensive to 10- 20 points. "photoelectric Co., Ltd. Shenzhen Crystal Taiwan strategic research director Zhang Lei told reporters.

"In the current market, in wide circulation COB products, for example, we use the 1734 models of wafer chip that circulate in the market unit price of about 135 yuan / K. Under the same size, the same luminous efficiency of the situation, homemade chips, its price is about 90-100 yuan / K. "Crescent photoelectric Co., general manager of Shenzhen Zou Yiming told reporters.

Meanwhile, the reporter learned through visits, although cheaper than homemade chips imported chips, but that does not mean it will be in the product parameters down to leeward. In some areas, imported chips in performance even further than domestic chip.

"Take the example of domestic Sanan chips from our test results that, it's no better than small and medium-power chip Epistar of Taiwan to be worse, but in terms of power, maturity compared to the Taiwan-based chip, which is slightly lacking from the situation we had the use of domestic high-power chips seems there are a lot of customers to reflect, it still can not achieve product stability as wafer level of such imports Puri chip. "Lei said that the current crystal sets photoelectric small power sources to domestic Saman, Huacan chip-based, while the premise of high-power light source aspects and customer requirements, they will adopt the imported chips.

In addition, the reporter also learned that the current in the LED chip industry, there are also differences square pieces with raw footage, which also contributed to the emergence of a post currently source products are the main factors.
"For example, the same brand of chips in the production process will be a positive band and partial-band products, we make white light source, and more will use blue band between 450nm-460nm, but some manufacturers will buy some partial band products, such as for example, or some high voltage and the presence of leakage risks chip 445nm-450nm this band for production. "Zouyi Ming said under normal circumstances, these chips are not in accordance with the normal price to purchase, but at most half the price of regular chips.

Gold is currently in light industry, the line is divided into two: one is pure gold wire; the other is the alloy wire. From the current market distribution, circulation area east and south China with more gold or high gold-based, but the wire is not a small proportion still exists. For example, known for cheap route known Lighting Capital - Zhongshan, companies will be using most of its light alloy wire, the printing of gold wire has been difficult to see.

"If the gold standard of 1.0, a single volume 500m length measurement method to measure the current 25μm in diameter gold wire price of about 1000 yuan from top to bottom, and with lower gold content, its price will gradually decline, for example, 60% of the content alloy wire, its price will be around $ 600.

Next is a silver-based high content silver alloy wire, its price is about in the range of 100-300 per month, and then followed by the unit price of 50-60 dollars of copper, which is currently the most expensive synthetic lines. "Silicon Technology Co., Ltd. Sigma director Yin tree Yuan told reporters, gold wire and synthetic gold, the price gap between the cost of different materials is extremely huge.

In addition, led street lighting fixture also learned that the current gold wire diameter is divided into 25μm, 27μm, 28μm, 30μm in four different sizes. Its different diameters at different construction costs also reflect the same time, it also exists for the product quality and a certain degree of influence.

"Obviously, the finer the gold wire diameter, its price will be lower because the LED light source at work, it is extremely high heat, while it goes out, the temperature would drop dramatically due to thermal expansion and contraction principle, the diameter is too low, the tension is not strong, then it is likely to cause the emergence of Weld, disconnection and other conditions, which leads to problems with the overall quality of light. "Zou Yiming, said, 25μm 28μm compared with pure gold wire specifications, it's 300-400 yuan price will be cheaper, but the product stability considerations, the industry in terms of COB devices still use more 28μm diameter gold wire.

Demystify revelation LED lamp power supply design

Here say is both constant current control mode switching power supply, resulting in the two approaches. These two approaches, either principle or device applications, or the performance differences are quite large.

        First, that works. The first kind of constant current LED dedicated IC now represented mainly as 9910 series, AMC7150, who is now playing constant current led street light with solar panel brand basically this, and told him to constant IC type of bar but I believe that this so-called constant-current constant current IC to do, the effect is not how good. The control principle is relatively simple, that is, the primary side of the power supply circuit, a current threshold is set, when the primary MOS conduction, when the inductor current is a linear rise, when up to a certain value, reach this threshold, then shutdown current, and then the next cycle is triggered by the trigger circuit is turned on. in fact, this should be a constant current limiting, we know that when the inductance of a different time, the shape of the primary current is different , although there are the same peak, but the current average value is different. Therefore, as this is when the power supply is generally batch consistency constant size is not very good control. there is a feature of this power, the general output current is trapezoidal, namely a fluctuating current, the output is not normally smooth electrolysis, which is a problem if the peak current is too large, LED will have an impact. If the power output stage and did the kind of smooth current electrolysis power, basically fall into this category. That is to determine whether this type of control, to see its output there, and on the electrolytic filter. I had this constant it has been called false constant, because by its very nature is a kind of limiting, not after the op amp compares current value is obtained.

The second constant current mode, it should be called a switching power supply type. This is similar to the control mode and switching power supply constant voltage control mode. We all know that to do with TL431 constant, because it has an internal 2.5 V reference, and then use a resistor divider way. When the output voltage is a little high, or low point of time, it generates a comparison voltage, after amplification, to control the PWM signal, so this control voltage can be very precise control. This control method requires a reference, further need a op amp, if the reference quasi enough magnification op amp is large enough, then given very accurate. Also, do constant is the need for a constant current reference, an operational amplifier, resistor overcurrent detection, as signal, and then use this signal amplification, to control PWM, unfortunately now is not good to find very accurate reference signal, commonly used transistor, this big do baseline drift, there is that you can get the diode conduction value of about 1V to do benchmarks, this can be not high, the best is when the reference TL431 op amp plus, but the circuit complexity. But doing so constant current power supply, a constant current or a good control accuracy more. And this constant current mode control, the output must have to add electrolytic filter, so smoothing DC output power is not pulsating, then no pulsation method of sampling. So to determine what kind of long to see whether there is an electrolytic output on the line.

Two current control mode determines the use of two different types of devices, thus determining the difference between the two circuit devices using different performance, cost is also different.

In 9910 the series as the representative of constant current LED power supply control IC to do, is actually limiting, control is relatively simple, strictly speaking, it does not belong to the mainstream mode switching power supply control, switching power supply control of the mainstream model is a must benchmarks and the op amp, but it can only be used for this IC LED, it is difficult for the other stuff, just because LED requires very low ripple. But because it is only used for LED, so now the price is higher. The basic is to use the 9910 Canadian MOS pipe production, the output of non-electrolytic, in general I see a lot of people just do labor word inductance inductance of power conversion. This power, general manufacturers of chips information out there on the map, basically buck. I do not say, good at this man more than I do.

Second, I represented, that is, the constant current driver switching power supply control mode. This is an ordinary chip as the core switching power conversion devices, a lot of this chip, such as the PI's TNY series, TOP series, ST's VIPER12, VIPER22, Fairchild's FSD200, and even with only MOS transistors or tubes RCC, etc., can do. advantage is low cost, reliability is good. Because the average price of switching power supply chip is not only good, but all through the extensive use of classic products. In fact, as of this IC integrates general MOS, plus convenient than 9910 MOS, but the complexity of some of the control, the need for additional constant current control devices, you can use the transistor or operational amplifier. The magnetic elements can be labor word inductance, can also be used with gas gap of high-frequency transformer.

I love to use a transformer, while the cost is low because the inductor, but I think it does not work with a load capacity, furthermore adjust the amount is not flexible sense. So I think a better device selection, the ordinary MOS integrated chip plus a high-frequency switching power supply transformer, from the performance, cost, are the best choice, do not need to go with what constant current IC, that kind of stuff, and difficult to use, and expensive.

Whether doing constant current limiting control of the power amplifier control or constant current power supply problems to be solved. That is, when the switching power supply chip work is to require a relatively stable DC voltage supply for the chip, the chip working current ranging from one to several MA MA. One elephant FSD200, NCP1012, and HV9910, this chip is a high self-fed, it is easy to use, but the high pressure feed, resulting in increased caloric IC because IC to bear about 300V DC, just a little bit Current even if an MA, but also consumption of 0.3 watts of damage. General led street lighting Manufacturer but ten watts, about the loss of a few tenths of watts of power efficiency can be pulled down a few points. There is a typical elephant QX9910., With a pull-down resistor to take power, so that the loss in the resistance, some also have it lost a few tenths of watts it. There is a magnetic coupling, is to use a transformer on the main power coil plus a winding, as an auxiliary winding flyback power as to avoid loss of a few tenths off this watts of power. This is why I do not have to isolate the power supply one reason to use a transformer, is to avoid the loss of a few tenths of watts of power that will be efficient to mention a few points.

Non-isolated step-down power structure is now widely used, which accounted for almost ninety percent or more fluorescent power. Many people think that not only buck an isolated power supply, a say isolation, they think the buck to think of the lamp safe to say - in fact refers to the power supply damage after just a buck, there are two basic structure, that boost, and buck that bOOST AND BUCK-BOOST, even after the two power damage. not affect the LED, there is such a benefit.

Now LED power, lamp manufacturers generally do require placed inside the tube, such as T8 tubes put in. Few external part. I do not know why this should be. In fact, the built-in power supply also difficult, the performance is not good. But I do not know why there are so many people so request. Suifeng Dao may have been right. External power supply should be said that more scientific and more convenient to my son. But I also have to Suifeng Dao, what customers want, I'll do anything but do built-in power supply, there is considerable difficulty Oh, because an external power supply, the basic shape is not required, how much do want to do much, it does not matter what shape would like to make. Built-in power supply, can only make two, one is the most used, that is placed under the light board, put the lights on top of the plate.

Here is the power, the power to do so would require a very thin, or does not fit. And this can only be the element fallen power line on only lengthened. I think this is not a good idea. But we generally like to do so. I do. There is less used, put both ends of the tube that is placed in two, so well done, the cost is lower. I have done, is the basic shape of the two built-in.

How to determine the strength and stability of the LED packaging factory product?

2014 draws to a close, and the beginning of the end product is generally going to be a plan for the next year, when the technology planning. For lighting companies, looking for a few more reliable packaging factory cooperation is the primary task, so a variety of audits began. That as our lighting plant engineering and technical personnel, how to judge from appearances strength and stability of a company? In addition to ISO documents, the need to look at what details?
LED packaging factory
First, clean clothes: buy led high bay lamps needs anti-static dust production and testing area. Protection of staff: a piece of clean clothes or split, and whether there is a ground wire and static lines. In fact, just a way to clean clothes product protection, the reliability of the product and is not significantly affected. By requiring staff to wear clean clothes is to make all employees respect the work of their own and others, for their approval to produce the products produced, providing employee pride. This is important if people think they are doing meaningful work, potentially will be more serious work.
Second, the work station setup: There will each work station is set to "a" shape, but also to "U" shape. The main job is to make workers and materials for transport, every time take the shortest path is a key indicator. As a packaging factory, established its position oven housing is particularly important, because the oven room is a solid crystal and wire bonders of intermediate stations, while the oven room temperature is high, also have an impact on other processes. Is there an isolation area to strengthen the dust dispensing station? Equipped with plastic powder control, this procedure affects the LED color temperature distribution yield, has not yet automated. As far as I can see, whether large capacity, or big name, a few technicians are in operation around the electronic balance. Spectrophotocolorimeter machine surrounding whether spilled material, which is very likely to cause mixing.
Third, the inspection records: packaging factory SOP documents pumping test every few hours tension wire bonders, solid crystal thrust, is there to do? What tools and equipment are detected? Many small factories are used to manually force gauge to test, likely to cause errors, it is recommended to use automatic push pull test machine, you can analyze the effectiveness of the model. Required to do, according to the provisions of checks, record statements of seriousness and orderly surface of the plant.
Fourth, product development engineering records: a product from scratch, how to provide for the use of the materials and verify? Large packaging plant materials used does not copy the packaging plant does not have the means of detection, which requires packaging factory engineers have seriously each material, from a long-term experiment to verify the stability of the material. If three or five months across a change even glue and phosphor materials and other major chip will prone to big problems.
Fifth, the lab's strength: led high bay light for sale always want to test the hot and humid, high-temperature aging, cold tolerance impact of these projects, the package that corresponds to the laboratory facility have the strength to do it, each batch is done in strict accordance with this it? What appears to have had a lot of testing on the company's product specifications, the results are not what laboratory equipment, so you do not shoot packaging plant it?
Overall: do not look at fame, see the strength! Do not look at the machine, see the instrument! Re-quality, heavy details of the packaging plant is king!

Sweden restaurant leverages LEDs to grow herbs and produce for in-house use

The Upper House restaurant located in the Gothia Towers building in Gothenburg, Sweden is using a Heliospectra LX60 intelligent horticultural LED lighting system to grow some of its own herbs and vegetables in small indoor gardens at its 25th-floor location. The restaurant has garnered a Business Restaurant of the Year award from a Swedish business journal called Dagens Industri, and the in-house horticultural angle has provided compelling scenes for guests to examine, while adding to the quality of the food.
Sweden restaurant leverages horticultural led high bay light manufacturers to grow herbs and produce for in-house use
LED-based lighting is proving invaluable for indoor farming, especially in commercial applications, as we noted in an article on lettuce and tomato cultivation. LED lighting with a specially-tuned spectrum can greatly enhance the productivity of a garden even in small spaces.
Horticultural LED lighting is critical in the in-house application at the Swedish restaurant. The head chef is growing items such as chervil, fennel, anise, cumin, and beetroot. The tuned spectrum accelerates the plant development. Meanwhile, the Heliospectra system also controls the delivery of nutrients.
For the restaurant, the in-house horticulture allowed it to raise its public profile and performance. "We have extremely high aspirations," said Måns Backlund, head chef. "By growing certain herbs and vegetables ourselves, we are giving our guests something extra and it is greatly appreciated and popular, too. "
While the small gardens can not supply near the full needs of the restaurant, the system allows important control of special ingredients. "We are not self-sufficient nor are we aiming to become so," said Backlund. "But it's a very exciting project and the produce we grow adds an extra dimension to our business. It's fantastic being able to pick something straight from the earth, taste it, and consider which dish it will complement. "
Heliospectra offers a broad variety of intelligent led high bay light for sale. Just the LX60 family encompasses products that range from 10.5W to 630W for applications ranging from the backyard to commercial farms. The networked horticultural LED lighting can dim LED channels from 0-100% for precise spectrum control, along with support for ventilation and nutrient control.

analysis of the LED bulb market

LED bulb is an alternative to traditional incandescent bulbs new energy-saving lamps, lighting currently used LED bulb adopts high power LED chip production, in order to prevent glare problems, housing is often used to create a frosted glass or acrylic. You can drive directly to the mains, most of the products have a wide voltage input, you can enter from AC85 ~ 269V. LED bulb uses existing interface methods, namely screw, socket mode (E26 \ E27 \ E14 \ B22, etc.), even in order to meet people's habits mimic the shape of incandescent bulbs.
Unidirectional LED-based light-emitting principle, designers made changes to the structure of the lamp makes light curve led street lighting Manufacturer incandescent basic point source of convergence. LED-based light-emitting properties, LED bulb incandescent lamp is relatively complex structure, basically divided into light, drive circuit, cooling device, together with these parts in order to create low-power, long life, high efficiency and environmentally friendly LED light bulb light products. So LED lighting products in the current situation is still high-tech high-tech lighting products.
As we all know, the current incandescent is gradually withdraw from the market, sales of energy-saving lamps are also declining, the widespread use of LED bulbs has become a trend. However, due to the long-standing traditional lighting effects on consumer use habits profound background, making followed the appearance of the structure and interface of incandescent LED bulb emerged.
It is understood, LED lamps and energy saving lamps are rapidly narrowing spreads. LED lights with conventional light sources, while having low energy consumption compared to the advantages of long life, but its high price has become a major cause of the outbreak demand hinder LED lights. But over the past two years due to the sharp decline in LED chip and packaging costs, LED lights price has also gone down significantly.
2014 became the year of development of LED Bulb
Yet when the rise of the LED light source market is the energy-saving lamps and incandescent lamps with the same score in the world. With the rise of the LED light source market to carry out three male rivalry, enter 2014, incandescent slowly eliminated, shrinking sales of energy-saving lamps, LED bulb so that became the darling of the business.
According to statistics, sales of Taiyuan market LED bulb is more than twice the energy-saving lamps and incandescent lamps, full occupation of the market share of light sources, lighting, general manager of Thai Taiyuan Taiyuan to source products through one of the largest wholesale merchants Qisong Yue said 2013 also to the energy-saving lamps and LED bulb share the market into 2014 overall decline in sales of energy-saving lamps, LED bulb overall increase in sales was mainly due to LED bulb technology innovation, resulting in market share decline in the price of energy-saving lamps more be less, but the people there is a state to follow suit, no matter how much understanding of the LED, come in is to buy LED products, which also led to the sale of the business-oriented comprehensive LED turn into battlefield.
"Now I do not how to sell the store basic energy-saving lamps, and all are based on the main LED bulb, this stock has a good bulb tens of thousands, are dozens of pieces a day out to wholesale." Qi Songyue that description Road.
Price war in full swing traders do not make money make crying
LED bulb market, LED lighting is the most bloody cut-throat market. Under the fierce competition, in order to seize the customer, whether it is the upstream manufacturers or midstream operations center, to downstream distributors, all in an effort LED bulb prices, which also led to a small number of watt energy-saving lamps basically no market to speak of.
In Taiyuan market, some no brand based 3W LED bulb prices even as low as more than one money, the energy-saving lamp market to give a direct ban, and LED bulb is by taking a quantity of products, businesses in order to increase sales, both in terms of price competition, which also led to a lot of businesses operating LED bulbs do not make money make crying, this situation will result in reverse slow development of the market.
Some brands of wholesale merchants reflects the current market Taiyuan LED bulb is quite chaotic, especially consumer brand do not know, blindly focus on price, leading to the price of irrationality.
LED bulb price trend emerged, in addition to competitive market factors, material manufacturers to reduce the cost of procurement is a major key.
For a long time, LED light bulb is used, power supply, cooling accessories, such as prices continue to fall, but also to reduce the material cost of LED bulb to a certain extent.
Select high-quality brand is critical to the dealer
Currently I visited Taiyuan lighting market to see, more or less every merchant operating LED Bulb products, but for businesses in terms of what will become the second NVC brand, the second is not known Op. To co-brand must present the traditional lighting of the times would have known, there is a strong backing to support the brand.
Wright, general manager of the operations center in Shanxi Wu Renjie told reporters: "It just caught up with the advent of LED era, which for us is an opportunity, a challenge, fortunately, I chose a good brand."
House Renjie further said: "From the 2013 Wright started lighting, a lot of people are reflected in the high price of Wright's, but I personally think that a good product is not measured by the price, use the time to prove. now the market, brand-name products will certainly sell, but no quality assurance, no guarantee, it will cause in the future to give yourself a lot of trouble to do their own products to ensure that the customer is responsible for the first and so far Wright retail and light bulbs do works almost no return, year round snow Wright bulb also cut prices, currently led street light wholesale has been popular, mainly due to Wright's more wattage, color temperature is 3000K or 5000K, and on people's eyes are very moderate , to say the daily bulb shipments considerable. this also proves the importance of choosing a high-quality brand of dealers. "
LED Bulb widely used, an overall increase in wattage specifications
According to my understanding of market visits, LED bulb has become an indispensable product we also become the largest LED lighting products, and LED bulb has a wide range of uses.
Taiyuan Shuai Hua Wei, general manager of Star Lighting Science, said the current widespread use of LED bulbs, but also to a sharp increase in sales of products, small wattage CFL basically LED bulb to replace, like 3W 5W 7W 9W bulb is widely used in Down inside, and now low-pressure lamps, European-style lights, Yuba, street lights are widely used in LED bulb, but to go on the market or in the largest of 3W 5W 7W bulb.
Shuai Wei school also said, LED bulb market space will become increasingly large, it is understood, as the technology matures, LED bulb specifications are gradually increasing, the current market has emerged over the bulb of 30W.
Shuai Wei school also said, I believe that in the near future, LED warm white bulb will launch out conversion bulb, LED bulb in the spring has fully arrived.
I visited a number of days, according to the survey view, LED light bulb has become a flagship product, incandescent and energy-saving lamp market will continue to shrink, LED bulb ample period has arrived.

The eight suspects of LED lighting industry in 2015

2014 for the LED lighting business is a challenge harvest year, cross-border Gangster "invasion" LED industry, the rise of the electricity supplier O2O, the rise of intelligent lighting concepts ...... these are not without trigger LED enterprises face every day is not the same adjustment in 2014 will soon be over, waving to us in 2015, then in the new year led high bay lighting wholesale will be how to develop it? The following are the eight LED industry guess!

1, the new Chinese lamps popular: With the rise of China's comprehensive strength of a big country, big country to catch up with Europe and America, every continent in the world is bound to set off a "China Dream" Renaissance style storm, with today's technology and materials, "high imitation "China wind style lamps will be sought after by consumers around the world!

2, intelligent lighting began to rise: intense competition LED lamps, LED advantages of regulated more and more obvious, the major manufacturers in order to stand out from the competition, no flame on a simple price, while technically improve their competitive intelligence and capabilities of intelligent lighting will be a high-profile hit the market.

3, the pan-home lighting gratitude boom: the harsh competition in the industry as home lighting, home lighting gratitude of the whole old, have smooth lighting products proposed pan-home lighting gratitude began to rise, a variety of styles, categories of home lighting also appear in a store have been common.

4, a single product alliances: With the industry brand development, centralized orders. More and more manufacturers alliance hold together the advantages of a single product development.

5, lighting Eclectic popular: led high bay light supplier diversified development more widely, from the process, materials, styles, colors and other topics is not a single element, lighting mix and match elements will gradually get consumers!

6, selling software status highlights: With the strong development of the electricity supplier, OTO and other sales model, similar to the lamp with the software and data analysis software sales will become a standard tool for lighting industry.

7, bio-light a star: With the rise of the health industry, bio-lantern entering a golden period.

8, engineering lighting market rebound: big market downturn will get warmer, the government will make the appropriate regulation, project lighting market will get warmer.

LED lamp beads development trends

This is due to write the headline message before a friend asked me to see how China's LED market. Dare to write something unfamiliar to mislead you, so just write about changes and trends buy led high bay lamps this small market, to bring the development trend of LED devices in the eyes of an engineer.
One, SMD 2835 turned gorgeous
    From the beginning of the end of 2011, there has been SMD2835 this device on the lighting market. The beginning of the stent design from SMD3014 bracket, solid crystal location directly on the pad, cooling area larger heat conduction path is shorter. At the same time by the lighting market demand for luminous flux, luminous flux output single product requirements higher. Due to the larger solid crystal position, more chips can be arranged to form a certain string and combinations. This gives packaging factory brings more opportunities for product positioning.
Power: Now the market common SMD2835 from 0.1W ~ 1W have, change to a different scaffold materials and substrate can be achieved more product categories.
Material: 0.1W stent is made of plastic and iron substrates PPA produced, 1W substrate will adopt copper, plastic materials, some manufacturers use PCT.
Voltage: For voltage speaking, 3V ~ 45V has. 3V using single or multiple satellites in parallel. Some companies are using higher voltages more stars 3V chip series, there is also high voltage chip production.
Trends: Domestic companies are the main push SMD2835, now Taiwanese companies and Korean companies are ready to develop SMD2835 this product, along with a further increase power, and cost requirements for lighting companies to replace SMD5630 is just around the corner.
Two, SMD5630 dynastic decline
Speaking SMD 5630, the first to mention, of course, the Samsung LED backlit TV. With LED energy-saving effect gradually reveal, growing, increasingly thin LCD product size dimensions. Backlight requirements are also increasing. Traditional T1, T2 section at the bottom of the tube light mode can no longer reduce the thickness of the machine. led high bay light for sale are able to meet these needs constant good. With respect to the smaller power LED, SMD5630 can provide more flux, better design method, the side light arrangement.
From the power of speaking, SMD5630 power products can provide higher heat dissipation than SMD3528. Support structure design also allows for heat dissipation and light output. In the lighting industry, due to the linear lamps, tube lights alternative markets such as the outbreak of more inspired SMD5630 expansion step in the lighting market. SMD5630 were making use of the lamp can be light-efficient products, and its optical design is also more conducive to the use of linear lighting market. Currently Korean series, the Taiwan-based firm's major competitive market is SMD5630, SMD5630 which forced prices have been falling. After entering the lighting industry, companies require even more than the cost of the backlight. More price decline led SMD5630 products. Meanwhile, the cost of future breakthroughs more bottom line, instead of using SMD2835 SMD5630 is already a big trend.
