How should LED lighting industry promote its value?

Since the arrival of micro-channel era , recently pulled into a lot of micro-channel group , every day is still the overwhelming industry information , while the popular focus are: 1 , the electricity supplier ; 2 , the promotion will ; 3 , channel expansion mode ; 4, the product ; 5 technologies; 6 , the price ...... come and go all channels, products , policies for each enterprise to share specific examples and how to do the problem ; actually the past few years to nearly two years of blog microblogging again to the present micro-channel , the circle has been hoarding a lot of lighting industry can learn from the information content , and on the work of recent years was engaged in the led outdoor lighting wholesale industry because of children's shoes carefully collect , summarize, summarize , visits, communication, learning , financial the Department has also become proficient road lighting experts and scholars ; this is a good thing, because the information developed and highly transparent , with no industry experience to do things the old , but set more wisdom , wider vision, innovative thinking and a larger platform to co-ordinate the planning and implementation of ;

    Engaged in the lighting industry for more than ten years for me , maybe a little stubborn and rigid thinking , there are many things that do not agree with a lot ; while he also constantly reflect on ourselves : do the lighting really simple? Ask TCL, the United States may have a stomach of grievances ; ask NVC , Op, three male Aurora , sunlight, Foshan lighting will transition worries ; ask Philips , Osram , GE technology and the times will be helpless ; ask Linsen , rectangular , Everlight , country star will grow bitter ; ask Sanan , Epistar , Samsung, Sharp , Citizen, Cree , Bridgelux market penetration will be confusion ; ask owners to face some of the lighting designer when there are too many helpless sadness ...... of course , including some made ​​of a single product , do OEM, make a nice integrated planning are relatively moist businesses , where we only summarize the vast majority of the common problems is concerned ; fact " lighting " is a general term of the entire industry ; from hardware , chips, and even the power to the light source lighting products, light from the mode of operation , outdoor , indoor, decorative , such as different product lines , ranging from enterprises and dealers to professional service organizations throughout chain have too much space for the presence of various segments of the market operability ; however , lost in the competition , in the development of confusion, which has long been a common problem for many companies , of course, including my own ; growth in learning , summed up in experience , adjust the LED lighting industry has become a problem in every business encounter and must be experienced in action ;

    How to enhance the value of the lighting is constantly thinking about their own problems , including: 1 , development direction and shorter deployment planning , long-term ; 2 , brand positioning , aspirations , dissemination and formation ; each 3 , product positioning conferred fusion kind of competitive advantage ; enterprise capabilities and features can support , carrying the selected channel mode , and integrated support and operational support services , etc. ; fact , swarm into the new generation LED lighting business , the most difficult is not the product , not the costs, not technology, not the supply capacity of the channel is not a breakthrough, not marketing personnel ; but most companies put into a business career , look to the lighting market is only a vague concept , focusing on short-term benefits , have business to do , what what to do, there is no clear market positioning themselves , no one can sort out their long-term development and planning mainline brand manager ; this precisely reflects the current lack of lighting many new military understanding and awareness of the so-called development bottlenecks arising from the crux of the bottle where ;

    One of the problems , the enterprise ; in LED lighting industry in the new army , and regardless of the form in which to enter the field of lighting , most of their own point of view to do standing lighting , lighting can really do the business from the perspective of another how much ? Many companies are still considered desirable to integrate these products to open stores to reflect the competitiveness of the product line , or to make a single product designed to do two dagger weapon formed through wholesale distribution , as long as a certain leveraging breakthrough, open up the middle vertically connected downstream enterprises naturally marching toward idealistic goals ; actual fact, although we can also pleased to see some of the good momentum of the new army , but it must be tough the next two years before the most critical ; put it plainly, newborn the current generation of corporate good momentum in recent years mainly benefited the muddy Bureau , experienced and professional managers ground gas identify gaps in the market , temporarily seize the current good start and won ; but with the traditional lighting companies positive battle yet to come , 2015 is perhaps a ridge. Therefore , I think the greatest value of the lighting business is still reflected in the architecture to improve and reserve personnel , from the idea of ​​the entire disk , planning, layout , implementing a full range of professional functions positions people in place to achieve the same objectives , acting , consistent with efficiency , enterprises can seize the opportunity and the release of the real powerful integrated combat ; practitioners in my ten years experience in this regard in the deep , concentrated mainly reflected in the crux of the structure and management , and this is my opinion planning the importance , of course, was somewhat sweeping ;

    The second problem , the brand ; any business to make some money , and further development , or development camp which turn to the more speculative market behavior or development mode, this is normal, because the growth is no standard can learn everything only from their own ; But Brand the form is not claiming credit for themselves will be able to do it, it needs to feel an emotional touch to the consumer from the perception of the formation, thus reflected the value of the goods is the key to the formation of the brand ; Therefore , companies from planning, deployment , initiating, implementing formed to represent the brand and what the companies want to pursue anything, but the key is to reach the final goal of a business to adhere ; reason for the confusion is due to ignorance , because still fumbling , because the market for the recognition of impervious , naturally wavering , finally, could keep operating , but the direction was sour ; took nearly two years, the most popular channels and traditional channels electricity providers to expand for things , it's just an act business planning methods among implemented it , do not be as specific ways of the business operations straw ! Especially the electricity supplier for the current electricity supplier from the nature of the operation of the lighting , I have been skeptical , but also concern , from a rational point of view , the future has integrated lighting power on the downstream industry resource integration and service capabilities maybe there will be a platform provider , but certainly not new to come out of the enterprise alone and facilitated .

    Moreover , the current industry is still in a full range of competitive products , competitive prices , channel competition stage , to survive ? To develop ? To break through ? Rushed to say the practice is totally understandable , because they are so came to be. But if we ignore the point of what ? What do we sacrifice ? Unforgettable brutal competition in the market of two , might not have to measure and critique what we get . But according to most mainstream mode of operation and competitive manner , resulting homogenization of each company's products will gradually lose power ; the true face of the traditional brand of confrontation , your terminal capabilities , channel capacity , competitive product line single force on products , professional services capabilities, system operation capabilities, brand support force in what ? Time is running out , it will soon be verified.

    Three of the problem , the product ; inner circle earlier popular saying : No products based marketing is bullying ! I totally agree , because I love occupational diseases is a product of the study; any supporting point of marketing is always the product , but the product should be divided into separate attribute it? Wrong , the product is the whole marketing system in firearms, ammunition , weapons and products are the foundation of marketing products in the development of marketing must be integrated into the connotation ; But many people can not solve the real value of the product , it should be given a combination of industrial design, technology, marketing concepts, cost , productivity, on-site installation and a series of basic requirements. In fact, many people believe that only products with high technological content of products with more value , this understanding is wrong. led outdoor lighting wholesale  products can also produce high value returns for businesses to better control costs , improve production efficiency , easy to keep and circulation of goods , capital turnover rate is conducive to enhancing marketing tool , to enhance competitiveness , market adaptability , share, for businesses operating efficiency and competitiveness are of crucial important role , it is cut and remove obstacles to market the most basic protection ; while for consumers, the general public , to achieve easy to use, durable , affordable facilitate both , without giving too much of the so-called professional content to flicker ; weapon technology and professional products , brand weapon , value-added weapon, of course, they will inevitably go to supporting professional services , why some multinational companies have relatively leading core technology advantage ? It is inevitable it? A British customer told me about a well-known brand in the UK domestic lighting market situation : "They rely on low-end cheap T5 products have a good market ." After listening to my strong feelings , no sustained delivery of innovative technology , not regularly highlights of new technology products with the release of low prices alone , once inside , the brand will freeze , and this worth it? In turn ask : could not find a valid starting point, has been stagnant , useful? Oh ~ This is called entangled ;

    But no doubt , by the low-end cut , to seize the market , pocket money only to the higher goal of forging ahead , it is not impossible , but how relatively high , medium and low three-way enterprise product planning are clearly difficult many ( order: conceptual , core type , fighting type ) . Moreover, technology is always sustained competitive enterprises play an effective weight is a strategic foundation for the brand gilded ; can do, Why not consider a more long-term development planning? So the car , appliance so , electronic digital products so , furniture, clothing and so much of the industry is also the case ? On the lighting industry, many of our companies do business worldwide , but the worldwide famous brands do it? Achievements allow foreigners can also really respected mainstream brands do ?

Innovation will die but pirate will is getting strong

Read an article , head out of nowhere saying , in our great country , it is a living reality , for innovation and engineering are a harsh reality .

Foreign entrepreneurs who are mostly engineers or technical staff , or students, they have a technology or a new concept , the idea , it will apply for financing, will concept , the concept into reality , to bring convenience , while others , myself also gained social recognition , while getting paid deserved after paying Microsoft's DOS is not it , Apple is not it?

Most domestic entrepreneurs are business people , they are a bigger volume of business when there is entrepreneurial impulse, once the order has been able to support starting a business and they will start all over again , great great work, so their stoves at the beginning of the product only old club ideas and concepts , so in our led indoor lighting wholesale has a circle like this , what David X series , X series blue , Long X series , X series , and so willing , if you look at every a series of products, you'll summed up a common feature , which is a very interesting thing , of course, there is such a system in the foreign trade , within their lines are complementary and mutually perfect , but our country within this system , is competing with each other to beware of , even antagonistic .

In foreign new technologies and new products will create a healthy new markets , while domestic new technologies, new products will create a very bad market, from the LED display, the LED lamps, LED can say the current market is a very Premium market ? Other industries are also like this, this is the situation .

Innovation will die ? Because innovation to put a lot of resources to support every detail of the product needs to be considered accurate , it is also repeated again and again into investment products on the market for the reference of the few, so every domestic innovation were to end up in the capital exhausted, while the cottage ones? Because of the physical reference , they can ignore the details of the defects , after a simple copy is as simple as copying a piece of paper , you can openly market. Innovation as maternal scheduled to go through the pain of childbirth , and copy those directly get other people's children , while undergoing a painful process of maternal birth to a child, do not enjoy their grandchildren , but almost no sacrifice adopter directly enjoy the family, even her body has not been restored yet , you suffer the pain of missing children , and poor nutrition , can live well ?

This phenomenon in the various industries in our country are real .

While entrepreneurship is not necessarily die , but will not live very well, especially for those entrepreneurs, cottage certainly be strong, at least for now look like this .

What causes this situation?

Probably heard of curse words , think of those corrupt officials being held up , and which one is not sanctimonious froth at the mouth of the day talking anti-corruption , flaunt their great achievements, but night is coming when you hug lady, mouth, pigs and dogs than doing flies delicacies born , the same word, " calling the shots " , there is such a place officials have habits, so the local habits once up Yingyinggougou , social trends will be better ? Industrial atmosphere will be good ? But these will certainly be remembered either official history or unofficial history. ( Alas pull away, stopped, shut up , palm face , remember not to remember me this Caomin hairy relationship )

Our patent department every day in the audit of the patent , but the patent protection of subsequent actions it? They might push for the " authorities ", and this is the reality of led indoor lighting wholesale , sad intellectuals , local , relevant Chinese characteristics , international standards , etc., as long as people are fake with a smooth and stately rhetoric , those who say it is ? ( How and deviation , and then Zhangzui )

Of course, much of the learning is currently under the command of the Prime Minister under the guidance of Lee , innovation will die, the cottage will be strong one day turn .

LED display without creativity and without market

No Creative No Market, no innovation would be no market . Borrow recent network hot words No X No X word to describe the current LED display industry is most appropriate . Each LED enterprises in the technology is mature , product range, price competition, service awareness to strengthen the case , making the led street lighting Manufacturer survival increasingly difficult environment . LED display enterprises only on technology, products , innovative services to meet customer needs to meet in order to win the trust of customers and markets. In this process, some companies develop , there are companies were eliminated, but 2014 is destined to become a LED enterprises between "life and death , survival of the fittest " in the market.

LED industry market problems resolved

1 , the lack of industry-standard products uneven market

Some companies market to compete with low-end products , the price war . Its feature is cheap, quality is not guaranteed.

2 , low profits financing difficulties

Excess capacity also led to vicious between businesses , the LED industry downstream enterprises falling product prices , profit margins are compressed. The gross profit margin LED display industry is currently only about 20%, while net profit is less than 5 %. SME financing is also an indisputable fact. External costs increased push to increase capital requirements , capital side is not loose in the case of SMEs access to credit resources are limited , to meet the financing needs of the low. Plus SME base is thin, the loan also increases the difficulty . Even borrow, loan interest and guarantee fees go up too high , but also to small and medium enterprises can not afford .

3 , overcapacity survival of the fittest

With the development of LED industry , many other industries have begun to enter the LED industry, which resulted in severe overcapacity , but also lead to further deterioration of the market environment . Excessive investment makes the LED display industry oversupply , many companies in the lower middle and lower technical barriers . Future LED companies will face brutal survival of the fittest . Only a few truly R & D, manufacturing strength of enterprises will gradually grow, but more enterprises will face the fate of being eliminated . Only a company savings continue to focus on talent , research and development to create a good environment , constantly doing fine and stronger their products in order to resist being defeated other competitors, and in its product areas and markets continue to develop , consolidate and powerful.

Transition segment LED display products , in order to account for a market opportunity, so that enterprises in the brutal competition in the market in which to survive , LED display enterprises are increasing R & D , human resources, market investment and allow enterprises to rising costs , delicate and difficult . Now the LED display market segments mainly in the following categories:

1.LED shaped screen market : ball display, square column screen , cylindrical screen, lantern display, energy saving display, flexible display, this part of the market is only a small part of manufacturers in the production , not competition , is only a small part of the market , does not exist suit production, technical threshold is high.

2 fine-pitch market : mainly used in the field of sophisticated end the country 's security monitoring and command centers , military forces , space launch , etc. , so that orders will not be much , but also the relationship between non-general , production technology and quality requirements are very high , challenging for many companies , and the smaller the spacing problem patchwork screen body should bother to do research, product success and adoption rate should reach 99% , this product only state-owned enterprises and listed companies on the scale we go shipped to market .

3 large spacing market : mainly used in the entire surface of the walls and roof of the building of the city center pole , similar to the Hilton Hotel in Jiaxing, Zhejiang roof to do a nearly 3,000 square meters of P52.5 led display . Shenzhen , Beijing-based 100 there was " Tyrant " four hours to spend 4.8 million behind Chen , amazing how advertising revenue.

4 General Market : Indoor single color is already in China for almost 20 years , module manufacturers do not how willing to do, indoor surface mount unit board wholesale , fierce price war has already begun . Secondary production of such products wholesale business too , and says that this product is simple, large , large market . But do these products subject to the light tube and chip manufacturers, wholesale upstream firm determines how much the market can go and how far .

5 leasing market : products in the leasing market , the vertigo burn chaos specifications make this market has been kind of too much, a lot of R & D investment , tooling costs , product updates quickly, from the original casting imitation Belgian Barco aluminum box , and now brushed aluminum casing simplistic .

LED companies when the product does not have to do everything, everything whole , we must form their own unique style, characteristics of the product , by one or two high-quality products , driving sales of other products . LED spherical screen , cube, cone , cylinder screen, energy saving and environmental protection shaped, personalized products to meet customer needs. The exhibition is seizing Kangshuo demand innovative products , has been at the forefront of the industry.

Not only do led street lighting Manufacturer to meet customer needs , but also make innovations in the service, rather than sit back and wait for the service to take the previous model, the problem until customers come back to the LED companies handle customer questions and objections. The service should allow the company to go out and take the initiative, the timing of customer pre-sale , sale and return visit . While customers in the process of using the product , you should regularly visit , collect customer usage experience, customer feedback summary problems in a timely manner to the appropriate strategies to solve customer problems and troubleshooting .

LED display enterprises in the products, services, markets have only innovation , only innovation can develop, even only innovation in order to survive . It is No creative No Market.

who dragged the hind legs of LED lighting industry?

" Wall Street Journal " article entitled "Who in the Chinese economy dragged the hind legs ? " The article pointed out that China has about 150,000 state-owned enterprises, which controls about 50% of the country 's industrial assets , absorbed about 20% of the national workforce.

Chinese state-owned enterprises contributed about one-third of the country 's economic value added . However, China's two stock exchanges in 1,500 companies , it may be only about 50 are truly private enterprises. State-owned enterprises have been strong government support , but still can not keep up the profitability of private enterprises . Will provide jobs , pay taxes and outputs , the private enterprises are much more important than state-owned enterprises . Private enterprises to provide about 80 percent of urban jobs , 90 percent of net new jobs , as well as two-thirds of investment in fixed assets . Article Conclusion: SOE drag on the Chinese economy.

Temporarily above the neutral point of talking about sex or biased . But it became evident that there must be some in the Chinese economy dragged the hind legs of factors exist , then the led street light with solar panel industry , and what factors hinder it ?

First of LED standards are likely to lag .

At present , China has LED lighting standards promulgated a total 111 levels , including a total of 36 LED national standards , has been approved and is being drafted by a total of eight LED national standards , national standards for the proposed project of LED 20 . LED industry standards that have been issued a total of 56 , LED local standards that have been issued a total of 19 .

But deep LED industry colleagues still clearly felt the standard lags behind the development of products, which is mainly due to the development of LED technology, rapid product replacement and product development from initial LED lighting alternative to manufacturing in line with the characteristics of the LED itself restructuring and other factors.

Overall, the international standardization organizations have developed many types of standard , reflecting the full attention of standardized situation, but some standards, norms duplication and contradictions , especially in traditional industries affected by some applications and standards technical focal bondage and blind spots caused by the presence of a technical standard scientific problems.

In addition , the industry standard is not standardized, industry, product quality is also likely to cause uneven .

With the improvement of people's sense of safety and environmental protection , in particular to strengthen the construction of ecological civilization , social security, environmental protection put forward higher requirements to be as energy-efficient LED almost synonymous with environmental protection , how to make people feel safe environmentally friendly products have become competitive an important indicator.

Therefore, rational planning of LED standardization work content and processes suitable for China to develop national standards for LED , so standardization work in close contact with the market to make LED industry standards are not dragging hind legs , so that product quality is not dragging the industry back.

Having a standard LED , let us talk about innovation.

CPC Central Committee and State Council recently issued a "national new urbanization plan ( 2014-2020 ) " ( hereinafter referred to as the "Plan" ) . As a future period to guide the healthy development of urbanization in the country 's macro , strategic and basic planning , "plan" for including the LED industry, including many industry will have a positive effect.

Accelerate technological progress and industrial upgrading , after a sharp decline in costs , LED product applications continues to increase, the growing size of the market , three to five years , LED lighting needs scale compound growth rate of 30 % to 40 %. And policies to promote demand-driven , LED backlight applications from industry driving force applied to the lighting changes from 2013 to 2016 LED lighting penetration rate from 10 % to about 50 %.

Faced with such great prospects , business expansion is mustering the strength of the grip orders.

However, the current lack of industry innovation capacity problems which exist in many companies , market competitiveness and risk-resisting ability of these enterprises is not as strong as they inevitably sink like a stone in the led street light with solar panel competition.

Reflect the current lack of innovation capability in three areas:

First, inadequate investment in research and development , technological innovation capability is weak , the transformation rate is not high second , original innovation and integrated innovation capability is not strong , the field of science and technology of high-tech pilot weak, slow development of strategic new industries , high-end dependence on imported products . Third, innovation efficient allocation of resources and comprehensive integration capability is weak.

It seems that the market prospects , companies do have a trip from the city in innovation .

The niche LED markets maybe takes another wave of demand

LED lighting market is the fastest growing market capacity is also the largest . LEDinside estimates that in 2014 the overall LED lighting market value of $ 35.3 billion , representing a growth of 47.8% in 2013 , 2014 LED lighting penetration rate will increase to 32.7 %, of which the lamp bulb and 20% , respectively, with penetration 15% . Just like a blue ocean .

But companies in the LED lighting applications market competition is the largest international lighting manufacturers , as well as new entrants into the traditional lighting LED lighting field, " outsider ." led high bay light supplier
 can be described as a prosperous , brilliant. Each LED lighting manufacturers to quickly grasp the fierce market competition .

There are also some companies began targeting LED niche market , it is understood , LED current in new areas such as security equipment , automotive and communications also shine.

In recent years, various lighting LED lights heavyweights have entered the market . In addition, plant lighting , UV (Ultraviolet, UV ) LED and other medical fields also have a place .

LED related to the use of the new market is small, those who invested less , although it is a small niche market , but the gross margin is quite high, Lunda ongoing research and development, and therefore can not generate immediate revenue contribution.

With the field after the LED backlight penetration reached 95% growth slowed down, leaving only the future to support the overall led high bay light supplier , LED manufacturers are therefore actively developing new applications , hoping to take advantage of high-margin , using a variety of niche markets , support from the new use , driving demand for another wave of LED.

How one hospital saw the light when it came to changing light bulbs

Light sensors have become an increasingly common fixture of modern offices, allowing facilities managers to slash unnecessary energy usage without having to constantly hassle colleagues to turn off lights. However, one of the most common complaints about these motion-detecting systems is that anyone who spends too long sitting quietly at their desk can on occasion find themselves plunged into darkness, which is the last thing you want if you work somewhere like a hospital.
Thankfully, this has not proved a problem at Bishop Auckland Hospital in County Durham where new ultra-energy-efficient lights and sensor systems are winning rave reviews. The replacement of about 60 40W led outdoor lighting wholesale with new ultra-efficient 21W tubes and the installation of lighting sensors on corridors on the ground and lower ground floors have not only helped to halve energy use, they have also made walking along some of the hospital's corridors a memorable experience.

Park Plaza reveals energy saving plan for all Seasons
"The feedback has been great," explains Andi Forrest, general manager for ISS Facility Services, the company that manages the hospital's facilities through its PFI contract. "People say it is like something out of the Matrix as you walk down the corridor and it turns on the lights. "
The lights typically dim, rather than turn off, when no one is around, but they are programmed to power up instantly as they are needed. They also deliver a better quality of light than the tubes that they replace, and as a result ISS has secured praise from hospital staff and patients for turning some of the darker areas of the hospital into lighter and more attractive places to work.
However, it is the cost savings that result from more energy-efficient lighting that are undoubtedly of the greatest appeal to the hospital's managers.
"Every penny counts in the NHS at the moment," notes Forrest. "So, if this technology costs a bit more upfront, that is not an excuse not to do it when you can deliver such big savings over time."
Significantly, the upfront cost does not fall directly on the NHS Trust as under the PFI contract ISS has access to a Lifecycle Fund that it uses to make improvements to the property at certain points through the contract. It is this that has given the company the freedom to undertake the lighting replacement programme and opt for the most energy-efficient technology they could identify. Forrest says making the business case for the improvements was actually remarkably simple.
"The business case for efficient lighting is really quite easy, because the savings are so clear cut," he explains. "It is more a case of just doing the maths and demonstrating the scale of the savings that are on offer."
Once the project was approved, ISS invited a number of vendors to come in and demonstrate their technology before then selecting their preferred supplier. Now, as the project moves into its second phase, the company is looking to upgrade again and is planning to deploy about 100 led outdoor lighting wholesale in the hospital's remaining corridors, a decision that promises both further energy savings.
With the reaction to the initial deployment having been "massively positive", ISS is now looking at how LED or other efficient lighting could be extended from the corridors into wards and other parts of the hospital. Forrest explains that lighting for wards in particular has special requirements - for example, overly harsh lighting or a movement sensor that plunged bed-bound patients into darkness when they needed the light on would not be suitable But the company has already looked at a number of efficient lamps that could meet wards' special requirements. and deliver significant energy savings. Wards are unlikely to end up looking like something out of the Matrix, but they could soon be helping to deliver significant energy savings, freeing up more money for the NHS Trust to invest in frontline services.

Top tips to help your business do its bit for the environment

As a business it is essential that you set an example for your employees and your customers to be more 'green', particularly given the current 'energy crisis' situation.
Helping the environment and being more energy efficient can not only help you to save money, but can also help you to attract a wider customer base, especially as many other businesses and consumers like to be associated with those who carry out 'green' practices; it's vital positive publicity.
The great thing is that being more energy efficient and more environmentally friendly doesn't mean you need to have a huge overhaul and change everything in your company at a large expense; it just takes a few simple alterations which could benefit you in the long run .
Change Your Lights
Lighting is essential in any business, you and your employees need to be able to see what you are working on and there are many regulations for different industries in which, lighting needs to be kept at a certain brightness and regulation. By replacing your lighting from traditional bulbs to led indoor lighting wholesale you could reduce your lighting bill by as much as 90 per cent.
As light contributes to around 40 per cent of your energy bill, you could be saving a substantial amount. Inui offer a wide range of LED bulbs and being 100 per cent recyclable, they are much better for the environment. LED lights can also help you to reduce your carbon emissions by up to 60 per cent.
Recycle Whatever You Can
Recycling is a fantastic way to do your bit for the environment, depending what industry you work in, you could recycle just about anything. Paper is one of the main materials to recycle, especially within the office. Cardboard boxes and other packaging materials are also great recyclable products, helping you to get rid of your waste in a much more proactive way.
It's also worth having relevant recycling bins, such as those for aluminium cans or biodegradable food waste, for employees to use - they're incredibly useful to have in our own homes, helping to reduce the amount we send to landfill, and tackling this on a larger scale in your business will have an even larger effect. Have a look at your company's waste and see what products could be recycled rather than thrown away.
Car Sharing
Encouraging car sharing is a fantastic idea that could cut back on fuel costs for you and your staff, as well as reducing your carbon footprint as there are not so many vehicles traveling the same distance and emitting hazardous fumes. It is an innovative way to encourage team building and friendships within the workplace, which can mean productivity is much more improved.
Another great advantage is that if you have limited parking at your business, your staff will easily be able to park, and there will be fewer issues with employees having to park further away or causing safety risks by parking precariously on site.
Turn Off All Electricals
If you work in an office based environment ensure that at the end of the day all of your staff are aware that they need to turn off all of their electrical equipment properly to ensure that there is no energy wastage. There's also the risk of reducing the lifespans of electrical appliances due to unnecessary overuse, as well as a potential fire risk as well.
Lighting should be put on a detection sensor so that if certain areas of the building are not in use, the led indoor lighting wholesale will turn off until the space is needed again. This is extremely helpful as many individuals can often forget to turn switches off, meaning you are paying unnecessary energy bills and causing avoidable damage to the environment.
Although none of these changes are extremely difficult to implement, they can make a huge difference to your business and to your contribution to the environment.

Three ways your warehouse is leaking energy and throwing away money

With many people trying to be more energy efficient and reduce their carbon footprint, it is no wonder that many businesses and companies are also trying to jump on the bandwagon and also go green. Here are some top tips to help your warehouse cut costs and become more energy efficient.
Lighting
Warehouses are large buildings with lots of space, and it's vital that it needs to be adequately lit, however, ensuring that the whole space is sufficiently lit means that you will need a lot of lights. By switching from led street lighting fixture to LED lights, you could save a lot of money by drastically decreasing your energy bill and, as they can last up to 50 times longer than traditional bulbs, there's a large potential for significant savings on outgoings for replacement bulbs. Not only can they save you money, they are also much more environmentally friendly being 100 per cent recyclable, having no mercury or tri-phosphor gases and reducing your CO2 emissions by up 60 per cent.
As LED lights give off very little heat, the need for air conditioning can be reduced, meaning your costs may again be cut - and just going even further to prove their efficiency, and that little to no energy is wasted.
Doors
You may not think that your warehouse doors have much to do with the energy efficiency, however there are a wide variety of ways in which they can contribute to your running costs and carbon footprint. With older warehouse doors being much more unreliable and extremely slow to open and close, it's not uncommon for them to be left open so they don't reduce productivity However, this means that heat or cold air -. depending on your type of warehouse and what it contains - is quickly released and your warm air heaters , air conditioners or cooling systems have to work even harder to keep the area at the optimum temperature.
High speed doors can reduce this waste of energy as the speed in which they open and close means that there is no impact on productivity and efficiency in the workplace, so they can stay closed until needed. More door providers are starting to stock and push these door types, such as UK-based Enerco, who provide high quality high speed doors for a range of different industries.
Work Vertically
With the help of new and improved handling equipment, many warehouses are starting to understand the benefits of working vertically and building upwards rather than spreading out. Extending upwards and making use of led street lighting fixture  means that many business owners are managing to save more money than they would have previously on land prices.
This efficient use of space reduces the need for onsite expansion or the need to relocate to a potentially larger premises, both of which could drastically increase your running costs. Relocation could also potentially mean sacrificing a great location, increasing the distance delivery vehicles need to travel , with all of these leading to an increase in carbon footpring.
Now that you know how your warehouse could be more energy efficient and reduce your carbon footprint, you can start putting these practices in place, helping you as a business to be greener and in turn do your bit for the environment. This could also increase your customer standing as consumers like to be associated with businesses that are greener.

The LED light fixtures are watching you at Newark Airport

We've already had London's rubbish bins snooping on us, US police wanting to tap into property owners' private security cameras, proliferation of gunshot-detectors, license plate readers popping up like bunnies in the spring - the US Department of Homeland Security is now seeking a national license tracking system - and even at least one drone purchased by a Texas police department.

That's already a lot of things watching us. Now, there's another.

As you turn your head to ponder what devices might be recording you, add an upward gaze, because led street light with solar panel are emerging on the list of potentially snooping, networked things.

Specifically, the New York Times reports that the clean, bright light of newly installed LED fixtures illuminating Terminal B at Newark Liberty International Airport, in the US state of New Jersey, are part of a new wireless network that's watching visitors.

The 171 LED fixtures are the backbone of a system that feeds data into software that can spot long lines, read license plates, identify suspicious activity and alert the appropriate staff, the NYT reports.

Executives in charge of the airport are already talking about expanding it to other terminals and buildings, the newspaper says.

The mass collection of data should certainly sound familiar to anybody whose head hasn't been under a rock over the past year (helloooooo, NSA!).

Likewise, data collection by law enforcement (or transportation security agents, in this particular case) is in keeping with the trend for US cities to increasingly gobble up data on residents.

The NYT reports that the Newark Airport authorities will maintain the data its networked light fixtures suck up and that no other agencies will have access to it without a subpoena or written request.

That may not, of course, matter. The need for a subpoena, written request, or even a reasonable suspicion of wrongdoing certainly doesn't stand in the way of the US government conducting surveillance or searches, as the controversy over NSA warrantless surveillance has made clear.

The lights have special chips and connect to sensors, cameras and one another over a wireless network.

The company that developed the system, Sensity Systems, is poised to take the technology much further, having already signed an agreement recently with a leading lighting manufacturer that plans to use the technology in its LED fixtures.

Sensity's leading executive told the NYT that the company's looking at video-based security, public safety, parking management, predictive maintenance and more.

Other cities, including Las Vegas and Copenhagen, are testing new street lighting systems to not only save on energy costs but to also do things such as control lighting, play music, issue security alerts, control traffic, monitor carbon dioxide levels, and detect when garbage cans are full.

Are privacy and data security concerns being taken under consideration?

Sensity, to its credit, has acknowledged the concerns of privacy advocates who say that the tendency is to suck up as much big data as possible first and then worry about securing it later.

led street light with solar panel has gone so far as to create a board to help figure out the technology's implications.

The data, in the meantime, is encrypted (though we have no more detail than that) and "supersecure", chief executive Hugh Martin told the NYT.

But it's perhaps best to be skeptical of claims that data is secure, let alone "supersecure".

We just marked the end of an epic year for data breaches, with over 800 million records lost.

It would be wonderful to believe in the claims that data being rolled up by places like this airport are going to be secure and that nobody's going to get at it without a subpoena or written request.

But there's hope, and then there's reality. Eight hundred million lost records. Goodness gracious, that's a lot of not-so-super security.

What do you think? Are you comforted by the idea of ​​more surveillance in airports, or have you had just about enough of the spread of surveillance technology?

Aquarium Lighting: Building a LED Fixture: How We Did It

In our previous article we considered theoretical aspects of reef lighting, such as the light spectrum and intensity required for growing corals and achieving their best coloration. We would now like to discuss the various practical challenges one faces when designing a led high bay light for sale for the reef tank .

Over one year has passed since the publication of our first publication on reef lighting. We planned to publish our second article on practical aspects of building a LED fixture shortly thereafter. At the time, we were actively working on the design of a special LED assembly that, based on our understanding of reef lighting requirements, would be best suited for a reef keeper's needs. However, we decided to postpone the publication, until our ideas fully matured based on our actual achievements.

As our work progressed, we decided to share not only theoretical stipulations, which were our starting point, but also the experience we gained through the efforts towards creating a light source that would not only provide for good coral growth but would also yield premium results in the visual perception of a reef tank.


The first part of this article describes how we planned our LED assembly; in the second part we describe our progress, in several successions, towards the latest version of our product.

We hope that our practical achievements, the problems we encountered, and our attempts at solving them will prove useful to the reef keeping community.


 Part One: Planning
When planning for a light source for a reef tank, there are many aspects that we needed to take into account. One challenge is the choice of LEDs that would provide for optimum efficiency. The next challenge is achieving uniform color mixing, in order to avoid unsightly color shades ("Disco" effect) in the tank. Another challenge is how to organize efficient heat removal from the LEDs. Last but not least, we need to "fill up" the spectrum, ie which supplemental colored LEDs to use for best visual representation of the corals. We shall consider these challenges in detail in the subsequent sections.

Choice of LEDs
It is evident that, whenever possible, preference should be given to LEDs manufactured by one of world's leading manufacturers: either Cree or Philips - they provide the best efficiency among commercially available LEDs today.


The specifications of many reef LED fixtures available today list the brands and types of LEDs used (such as Cree XT-E or Philips Luxeon Rebel). Yet, most manufacturers do not specify, the particular LED bins which they used in their fixture. Still , bins are a very important characteristic which we need to keep in mind when building a LED fixture.

What is a bin? Due to technological reasons, the parameters of LEDs can be different even within the same batch. To achieve a product with uniform quality, leading LED makers sort out their product into several categories, depending on certain characteristics, which they call . bins Color bins contain LEDs with similar wavelengths, or spectrum; luminosity; whereas, efficiency bins consist of LEDs that are sorted out according to the efficiency of converting the electric energy into light Each manufacturer assigns certain bin codes to these LEDs, and this. bin code is attached to LED model number in order to better characterize the properties of the lot that is offered for sale.

If we look at the offered color bins, for example, we can see that emitters with different prevailing wavelengths are available for the same LED type For example, consider the newest generation of Philips Luxeon Rebel ES Royal Blue emitters (Fig 1).:

image001.jpg
Fig 1 Peak wavelength bin structure for Luxeon Rebel ES Royal Blue emitters

The ability of the human eye to differentiate between close shades of color depends on the range. It varies from approximately 1 nm resolution in the blue-green and yellow wavelength ranges to about 10 nm or poorer for red and blue [1].

It is easy to see that by looking at the bin code. LED emitter's peak wavelength can vary significantly. Color bins can be very narrow, sometimes only 5nm wide or even less, and it is important to take this into consideration when we want the whole desired spectral range covered - otherwise we can miss some shades of color in our fixture's light.

The second binning category - luminosity or efficiency bins -. Is also very important The manufacturers use this bin type to sort out their LEDs according to the optical power output, while the electric power consumption is the same Even for the same LED type the difference. in efficiency between bins may be significant. Let us have another look at the datasheet of same Luxeon Rebel ES Royal Blue (Fig 2).

image002.jpg
Fig 2 Radiometric power of Luxeon Rebel ES Royal Blue emitters at 350 and 700ma, depending on luminosity bins

You can see that the efficiency of electric power conversion into light energy can vary from 37% to 53% for different bins at the same current. This means that the best bin is some 40% more efficient compared the worst bin!


Thus, by installing less efficient LEDs in a "cheapo" fixture, it will yield 40% less light compared with the use of best bin LEDs Yet, at a glance (and even according to fixture specification - if bins are not mentioned)., both will seem to be utilizing the same LEDs.

Of course, fixture manufacturers are tempted to use less efficient LEDs, since the best bin's price can be twice as much as that of the worst bin (besides, LEDs of topmost quality are scarce; they are usually not readily available for purchase and "catching "the best bin requires significant efforts from the fixture manufacturer).

. This concerns the LEDs of same type Price (and efficiency) difference between different LED generations is way higher Therefore, beware if a manufacturer only specifies that "the fixture is made with Cree LEDs." Without even specifying the particular LED type used. - it is most probable that the fixture may be using LEDs which are two or even three generations old, which offer mediocre performance, at best.

Unfortunately, manufacturer's interests do not always match that of the user. The cost of LED emitters is only about 20% of the total fixture cost, but this additional 20% expense can provide up to 40% extra light, and add an additional advantage, less heat generation and power consumption. If we consider a 300W LED fixture as an example, calculating for 12H daily operation, and based on a 15c per kWh power cost, the total power consumed in 10 years of operation will cost (300/1000 * 12 * 365 * 10 * 0,15) = $ 1,971 for a fixture with the worst bin, while the owner of a fixture with the best bin would save $ 788 throughout this period.

There are many other advantages in using led high bay light for sale with better efficiency, which are far more difficult to account for objectively due to many unknown variable factors. To name a few, less efficient LEDs will result in higher junction temperature during operation, which in turn, will further reduce their light performance and result in a shorter lifespan of the LEDs. The heat from a less efficient fixture will be transferred to the environment, and it is more likely that the tank and the room will require a more powerful cooling unit.

So far, our estimates were based on a 40% efficiency difference between the best and worst LED bins of the same type. Depending on the LED type, this difference can be higher or lower. If we extend our speculations and start to consider LEDs from different manufacturers, this efficiency difference can be much higher. If we compare low-cost Chinese LEDs, which now flood the market, with the best bins from the best manufacturers, there can easily be three a times efficiency difference, or even more!

In fact, this means that by choosing between two fixtures of same power but a three-times price difference, one may to yield less light per dollar from the cheaper fixture (this is true under the assumption that the fixture cost is directly linked with the cost of used materials rather than other marketing factors). At the same time, the less efficient fixture will spend much more in power bills in a fixture's lifetime.

Worst of all, it is almost impossible to accurately measure LEDs efficiency at home, and manufacturers are tempted to indicate a higher efficiency for the LEDs they use: serious errors in LED fixture specifications are common.

We believe that the choice of most efficient LEDs is very important when building a fixture. As we have shown, their higher cost will be justified in time.

There are a few other important issues which are often poorly addressed in existing fixtures.

We have heard claims from many experienced reef keepers that LED lighting has not yet matured for aquarium use We believe that this notion is caused by two main shortcomings of the existing fixtures:. Spectrum deficiency and poor color mixing which results in multicolored blotches and shades.

The first problem is relatively easy to address by combination of different LEDs in order to cover the desired spectrum fully (in our previous article we have shown that violet spectrum plays an important role but is neglected or poorly represented by most manufacturers, mainly due to the high cost).

The second problem requires a complex of efforts to achieve an acceptable solution. Some people spot these color blotches at once, while others may require time to notice the problem. Still, it is very important to eliminate this effect, as it affects our perception of the reef tank directly.

Challenge number one: Getting rid of color shadows (disco effect)
The so-called disco effect is witnessed when a tank is lighted by several power LEDs (especially multi-colored) which are positioned on a certain distance between each other. Each LED is a point light source, resembling a small sun. When illuminated by several LEDs from different directions, every object produces multiple shadows. When these LEDs are of different color, these shades look colored like disco lights.

The only way to overcome this effect is to place LED crystals as closely as possible. We cannot place all the LEDs of the fixture in one place, as we want to light up the whole surface more-or-less uniformly. Therefore, we need to gather all differently colored LEDs in groups, in the required proportion. These groups can then be evenly spread over tank's surface.

One option is to collect a group of LED crystals in a small space by creating a custom COB (Chips On Board) with many LED crystals closely packed in one case. A COB is a matrix of individual LED crystals attached to a common platform and covered by a protective compound (usually silicone) They have several advantages over SMD LEDs and are becoming quite widespread for general lighting use Indeed, they are easy to mount, provide a relatively low cost per emitted light, and are undemanding to optics -.. they are, indeed, very good when you need lots of light from an inexpensive fixture. COBs can be very good for the lighting of roads, warehouses, or other large premises.

Custom COBs can provide a perfect color mix if crystals with the right spectrum are selected However we believe that COBs are not the best choice for a reef tank Three factors are most important when building a reef fixture:.. Spectrum, efficiency, and optics.

In theory, a COB may contain any crystals. However, none of the top ranking manufacturers, neither Cree nor Philips Luxeon, cover the whole spectral range required for reef lighting. Cree, for example, does not make violet ("true actinic") ., or deep red LEDs, Philips Luxeon also doesn't cover the violet range Of course, there are smaller companies which make a wider range of LEDs, and their crystals cover the required spectrum However, our second requirement -. efficiency - would suffer . Theoretically, crystals from different manufacturers can be combined in one COB package, but this can be practically impossible for similar crystals, made by different brands. As a result, the COB will have to use crystals with significantly lower efficiency, compared with world's leading manufacturers Our calculations based on the datasheets from leading Taiwanese manufacturers -.. Epistar / Epileds, show that there can be as much as 54% difference in efficiency compared with best individual LEDs from top manufacturers Besides, manufacturers usually don't put their best crystals into COBs. Even Cree declares about 34% less efficiency for their best COBs today, compared with individual LEDs.

A shorter thermal path in COBs is usually listed as an advantage, however, this is not as simple as it seems. As an example, let us consider Cree's newest COBs. As one of World's top leaders in LED technologies, this company pays closest attention to improving the thermal characteristics of their products. According to the datasheets, thermal resistance of Cree's COBs varies from 2.5 ° C / W for CXA1507 to an impressive 0.8 ° C / W for CXA2530. Seems to be pretty good, huh? Only until we notice that, say, CXA2520 may consume up to 50W of power. According to the datasheet (see the picture below), this will add a significant 40С to junction temperature above the temperature of the LED case. For CXA2530, with 61W power consumption, junction temperature will be even higher.

The stroboscopic reasons and solutions of LED lighting products

With the gradual development of LED lighting , more and more customers will get the phone in front of the habit of shooting LED lamps , by observing the presence or absence of strobe lighting and determine whether the harm to the human eye . This approach is not entirely correct.

The traditional fluorescent directly for AC 50Hz , its strobe is 100Hz, when taken with a digital camera because the sampling frequency is different, there will be water ripples . The LED lighting is a DC power supply , the light emitted by the light source which will also be in the form of direct current ( DC superimposed on the basis of said minor fluctuations or pulsations ) , from a physical perspective, the luminous indeed much lower volatility the degree of fluctuation in the light source of alternating current job . However , the input AC power supply in the form of still difficult to completely avoid AC ripple through the LED light sources. So , when there will be a digital camera with led street lighting Manufacturer flicker of existence .

There are camera flashes can conclude that the human eye will hurt it? Fact, " the frequency of the human eye is sensitive to light of volatility in the low frequency range ," such as the frequency of ambulance warning light is about 8-10 Hz , most likely to make eye discomfort , which led to the alert. These frequencies are far below the normal range of the optical frequency of the AC power source to work , so " there does not exist a normal eye when the light source is not a comfortable situation to work under the current frequency of civilian power ." Currently a wide range of sources around the world are using the optical frequency 50-60 Hz ( including LED displays , LED TV ) , so that the LED lamps output ripple current 100Hz can affect the human eye is more imprecise comfort of this statement .

Vision can feel the strobe mainly by two factors :
       1, the output ripple frequency is low
Individuals under special conditions ( for example : region from matte suddenly into light region ) strobe will be felt around 100Hz , old movie frame rate of 24fps, but if the illumination flicker frequency is about 60Hz, all no law to endure , computer monitors and televisions out of the old standard frame rate , it is easy to understand. 2, the output ripple of the output voltage or current 100Hz ripple , when the ripple voltage is less than 5% , can not feel flicker . Then the ripple current may be smaller than 5% , to achieve a bit difficult.
Phone or video camera frame rate is generally around 30 , high-speed motion camera can reach 400fps. Shooting strobe lights, strobe frequency if the device can not exceed the set shooting frame rate four times on the device will be taken even see the lights flash has serious shake -hui , the results taken as well. So, shoot the old CRT monitor display , often see a bar move up.
Lower frequency strobe , although we can not be felt immediately , but long-term in this light, people get tired easily , prone to myopia and other eye diseases.

Purely in terms of the current LED power supply requirements are satisfied no flicker can be done . Roughly as follows:
       1 . Increase the output of electrolytic capacitors
(2) using passive PFC valley-fill program
3 using two programs (AC / DC, DC / DC)

The first plan " to increase the output of electrolytic capacitors " , this program can be used theoretically AC ripple electrolytic capacitors absorb some , but the actual experience tells us that when the ripple control within a certain range of the future ( 10% ) , difficult to further reduce , regardless of the cost unless Cadogan electrolytic capacitors , eliminating not fundamentally .

The second way " using passive PFC valley-fill program," This program is the most mainstream kind of approach. Non-isolated solutions commonly Shanghai Shanghai Jing Feng Ming or the duty cycle of the source program . Isolation scheme can be used ChipLink or IWATT ( the earliest programs , has basically been eliminated ) . Circuit works as follows . Using two large capacitors and three diodes for power factor correction , because in the back of the rectifier bridge has a large electrolytic capacitor , so the AC ripple absorption, the current through the inductor or transformer to the secondary part of DC .
 Transformer
However, valley-fill program there are some problems, first non-isolated valley type programs exist uncontrolled output load voltage , lamp beads likely to cause damage to fill . Secondly , you can not make 90-265V full voltage input , fill half of the valley valley only circuit output voltage electrolytic filter circuit valley , the valley-fill after the rectifier rectifier output voltage lower than the average rectified output voltage of a lot, there are may use the valley-fill in the low voltage input is insufficient load . Moreover, both isolated and non -isolated valley-fill program , harmonic test simply can not pass. Power factor can not be completely up to 0.9 . Therefore, such led street lighting Manufacturer can not fully meet UL, CE certification standards. Annex pages of test data .

The third way is to adopt a two-stage program in the Division I power on the basis of the existing isolation level back plus DC / DC, will be able to completely eliminate the effects of exchange ripple . Electrical parameters can fully meet the certification standards. However, this solution has some increase in cost , requires a power management chip Cadogan and some peripheral circuits , to increase the total cost of around $ 7. The following is a power of two common tests no flash :

     Currently the United States a well-known chip design company is developing a true internal adjustment through the chip to achieve no flicker . The technology uses a buck-boost after the first approach, the entire process is completed using a single chip to achieve a smooth DC output in ensuring the PFC and THD premise. Currently the product is in the development stage , has not yet introduced .

how should LED lighting industry promote its value?

Since the arrival of micro-channel era , recently pulled into a lot of micro-channel group , every day is still the overwhelming industry information , while the popular focus are: 1 , the electricity supplier ; 2 , the promotion will ; 3 , channel expansion mode ; 4, the product ; 5 technologies; 6 , the price ...... come and go all channels, products , policies for each enterprise to share specific examples and how to do the problem ; actually the past few years to nearly two years of blog microblogging again to the present micro-channel , the circle has been hoarding a lot of lighting industry can learn from the information content , and on the work of recent years was engaged in the led indoor lighting wholesale because of children's shoes carefully collect , summarize, summarize , visits, communication, learning , financial the Department has also become proficient road lighting experts and scholars ; this is a good thing, because the information developed and highly transparent , with no industry experience to do things the old , but set more wisdom , wider vision, innovative thinking and a larger platform to co-ordinate the planning and implementation of ;
       Engaged in the lighting industry for more than ten years for me, maybe a little stubborn and rigid thinking , there are many things that do not agree with a lot ; while he also constantly reflect on ourselves : do you ask a simple lighting actually TCL, the United States may be one ? stomach grievances ; ask NVC , Op, three male Aurora , sunlight, Foshan lighting will transition worries ; ask Philips , Osram , GE technology and the times will be helpless ; ask Linsen , rectangular , Everlight , country stars have grown bitter ; ask Sanan , Epistar , Samsung, Sharp , Citizen, Cree , Bridgelux market penetration will be confusion ; ask some of the lighting designer will be helpless when faced with too much sadness owners ...... of course , including some made ​​of a single product , do OEM, make a nice integrated planning are relatively moist businesses , where we only summarize the vast majority of the common problems is concerned ; fact, " light" is an overview of the entire industry words ; from hardware , chips, and even the power to the light source lighting products, light from the mode of operation , outdoor , indoor, decorative , such as different product lines , ranging from enterprises and dealers to professional service organizations , the whole industry chain will be broken down too There are various market space operability ; however , lost in the competition , in the development of confusion, which has been a common problem for many companies , of course, including my own ; grow in learning, summarized in experience , in action adjust the LED lighting industry has become a problem in every business encounter and must be experienced ;

       How to enhance the value of the lighting is constantly thinking about their own problems , including: 1 , development direction and shorter deployment planning , long-term ; 2 , brand positioning , aspirations , dissemination and formation ; each 3 , product positioning conferred fusion kind of competitive advantage ; enterprise capabilities and features can support , carrying the selected channel mode , and integrated support and operational support services , etc. ; fact , swarm into the new generation LED lighting business , the most difficult is not the product , not the costs, not technology, not the supply capacity of the channel is not a breakthrough, not marketing personnel ; but most companies put into a business career , look to the lighting market is only a vague concept , focusing on short-term benefits , have business to do , what what to do, there is no clear market positioning themselves , no one can sort out their long-term development and planning mainline brand manager ; this precisely reflects the current lack of lighting many new military understanding and awareness of the so-called development bottlenecks arising from the crux of the bottle where ;

       One of the problems , the enterprise ; in LED lighting industry in the new army , and regardless of the form in which to enter the field of lighting , most of their own point of view to do standing lighting , lighting can really do the business from the perspective of another how much ? many companies still think the ideal integration of these products to open stores to reflect the competitiveness of the product line , or to make a single product designed to do two dagger weapon formed through wholesale distribution , as long as a certain leveraging breakthrough, open on the middle and lower reaches of the vertical connection , companies naturally marching towards idealized goal ; actual fact, although we can also pleased to see some of the good momentum of the new army , but it must be tough coming two years before the most critical ; plainly , the current good momentum of the new generation enterprise mainly benefited in recent years muddy Bureau , experienced and professional managers ground gas identify gaps in the market , temporarily seize the current good start and won ; but with the traditional lighting companies positive confrontation is yet to come , 2015 is perhaps a ridge. Therefore , I think the greatest value of the lighting business is still reflected in the architecture to improve and reserve personnel , from the idea of ​​the entire disk , planning, layout , implementing a full range of professional functions positions people in place to achieve the same objectives , acting , consistent with efficiency , enterprises can seize the opportunity and the release of the real powerful integrated combat ; practitioners in my ten years experience in this regard in the deep , concentrated mainly reflected in the crux of the structure and management , and this is my opinion planning the importance , of course, was somewhat sweeping ;

       The second problem , the brand ; any business to make some money , and further development , or development camp which turn to the more speculative market behavior or development mode, this is normal, because the growth is no standard can learn everything only from their own ; But Brand the form is not claiming credit for themselves will be able to do it, it needs to feel an emotional touch to the consumer from the perception of the formation, thus reflected the value of the goods is the key to the formation of the brand ; Therefore , companies from planning, deployment , initiating, implementing formed to represent the brand and what the companies want to pursue anything, but the key is to reach the final goal of a business to adhere ; reason for the confusion is due to ignorance , because still fumbling , because the market for the recognition of impervious , naturally wavering , finally, could keep operating , but the direction was sour ; took nearly two years, the most popular channels and traditional channels electricity providers to expand for things , it's just an act business planning methods among implemented it , do not be as specific ways of the business operations straw ! especially the electricity supplier for the current electricity supplier from the nature of the operation of the lighting , I have been skeptical , but also concern from a rational point of view, the future holds the downstream industry resource integration and service capabilities of the integrated lighting business platform might appear, but certainly not new businesses emerge alone singles and contribute to the fight .

       Moreover , the current industry is still in a full range of competitive products , competitive prices , channel competition stage , to survive ? Want to develop ? To break ? Rushed to say the practice is totally understandable , because they are so came to be. But if we ignore the point of what ? We sacrifice what ? Brutal competition in the market both regret , might not have to measure and critique what we get . But according to most mainstream mode of operation and competitive manner , resulting homogenization of each company's products will gradually lose power ; the true face of the traditional brand of confrontation , your terminal capabilities , channel capacity , competitive product line single force on products , professional services capabilities, system operation capabilities, brand support force in what ? time is running out , it will soon be verified.

       Three of the problem , the product ; inner circle earlier popular saying : No products based marketing is bullying I totally agree , because I love occupational diseases is a product of the study; any supporting point of marketing is always the product , but the product should be ! ? division of independent property right the wrong , the product is the whole marketing system in firearms, ammunition , weapons and products is the basis of marketing, product development must be integrated into the connotation when marketing ; but many people can not solve the real value of the product , given that it should be combined with a series of basic requirements of industrial design, technology , marketing concepts, cost , productivity, on-site installation. In fact, many people believe that only products with high technological content of products with more value , this understanding is wrong. Low- value products can also produce high value returns for businesses to better control costs , improve production efficiency , easy to keep and circulation of goods , led indoor lighting wholesale  is conducive to enhancing marketing tool , to enhance competitiveness , market adaptability , share, for businesses operating efficiency and competitiveness are of crucial important role , it is cut and remove obstacles to market the most basic protection ; while for consumers, the general public , to achieve easy to use, durable , affordable facilitate both , without giving too much of the so-called professional content to flicker ; weapon technology and professional products , brand weapon , value-added weapon, of course, they will inevitably go to supporting professional services , why some multinational companies have relatively leading core technology ? advantage of this is necessarily do a British customer told me about a well-known brand in the UK domestic lighting market situation : ? "They rely on low-end cheap T5 products have a good market ." After listening to my strong feelings , no continued delivery of innovative technologies , new technology products with no regular publication highlights , low prices alone , once inside , the brand freeze up , it's worth it in turn to ask: ? did not find a valid starting point, has been stagnant , ? helpful Oh ~ this is called entangled ;

       But no doubt , by the low-end cut , to seize the market , pocket money only to the higher goal of forging ahead , it is not impossible , but how relatively high , medium and low three-way enterprise product planning are clearly difficult many ( order: conceptual , core type , fighting type ) . Moreover, technology is always sustained competitive enterprises play an effective weight is a strategic foundation for the brand gilded ; can do, Why not consider a more long-term development plan so it auto , appliance so , so electronic digital products , ? furniture, clothing and so much of the industry is also the case? on the lighting industry, many of our companies do business worldwide , but the worldwide famous brands do it? achievements so that foreigners can also really respected mainstream brands it?

       Do you pay attention ? LED lighting era, what was mentioned was the largest industry is the key word ? Prices ? Channels ? Electricity supplier ?

       Lighting industry in a few words is not clear, then apply the friend said : understanding the natural understanding. But it is not the same with other industries , this is the lighting charm !

The protection requirements swimming pools and fountains of LED lighting lamps fixture

Fountains and decorative landscape purposes, usually set in the public areas of openness. In order to increase the decorative effect, water tanks are usually installed in contact with water lantern, sprinkler and some of the supporting electrical wiring. Compared with swimming pools, fountains is an accessible waters in the summer, children playing in the fountains slapstick scene is very common, but there may be more complicated because the pool of electrical installations, compared with pools, fountains security problem is particularly important. Swimming pool, fountains and a wading pool , who want to enter the artificial waters, may install a sprinkler control and decorative electric lighting fixtures, but there is still a need for these electrical wiring system. When a person enters these waters skin may be exposed when the water insulated electrical device or accessory malfunction leakage, water, wet body, electric shock accident prone earth loop composed of the body by the disaster shock. Mandatory standards for construction of electrical area classification by the environment and the surrounding waters, the waters of the swimming pool and other electrical devices, including lighting fixtures, including the proposed safety requirements for swimming pools and similar fixtures of mandatory safety standards LED commercial lighting wholesale also made corresponding requirements.
I. Overview

1. Applicable Standards
Since the normal use of lower body resistance and human contact with the ground, swimming pools, fountains and a swimming pool, an increased risk of electric shock. For electric shock protection devices these regions, we have asked the national swimming pools and similar electrical devices and other pool building, for which the use of lighting, but also the corresponding product safety requirements.

Second, the origin of human exposure threshold voltage safety

Definition of total body impedance and the impedance of the human body and skin impedance vector (see Figure 4). Definition of a human body impedance is the impedance of the second electrode and the body contact between two positions, excluding the skin impedance. Custom skin impedance is the impedance conductive electrode and the subcutaneous tissue between the skin.

Total body impedance varies with the contact voltage of a variable. Total body impedance value is small, in the same circumstances the calculated current through the body, the greater the evaluation results accordingly given more security. Of course, the human resistance is not made as small as possible, so that protective measures would make excessive demands, so that the evaluation results are meaningless. Select the total impedance of scientific and rational human should consider two aspects of various factors directly affect total body impedance, and second, the results of the statistical distribution of the total impedance of the human individual differences in formation. 50Hz/60Hz total body impedance values ​​at higher frequencies due to the capacitance of the skin decreases. Dry conditions, a large contact surface, 50Hz/60Hz AC current path is hand-to-foot, 95% of the measured object incremental value of total body impedance 1000Ω.
a) In dry conditions, a large contact surface, 50Hz/60Hz AC current path of the hands and feet, the safety threshold voltage under 95 percent of human exposure conditions of the test object: Security under dry conditions of human exposure threshold voltage value = body under the current safety threshold × dry conditions the total body impedance = 50mA × 1000Ω = 50V.

b) in wet environmental conditions, a large contact surface, 50Hz/60Hz AC current path of the hands and feet, the safety threshold voltage under 95 percent of human exposure conditions tested object: the person in a humid environment, the human resistance will reduce , dry conditions in the human body is assumed that the total impedance of 100% water

Under wet conditions the total impedance of the human body under dry conditions 50% of the total impedance; human exposure safety threshold voltage under wet conditions = under current safety threshold of human × humid environment of total body impedance = 50mA × 500Ω = 25V ≈ 24V .

c) in saline moist environmental conditions, a large contact surface, 50Hz/60Hz AC current path of the hands and feet, the security threshold voltage at 95% of human exposure condition of the object to be measured: dry conditions assumed impedance of total body 100%, the total impedance of the human body under humid conditions with brine, water wet

Under conditions of 50% of the total impedance of the human body, that is, 25% of the total impedance of the human body under dry conditions. Then, in the saline wet conditions, compared with total body impedance 250Ω, human exposure safety threshold voltage under saline moist environment = lower body current safety threshold × saline moist environment of total body impedance = 50mA × 250Ω = 12.5V ≈ 12V. As the moist environment more suitable for saltwater pool and fountains, therefore, pool and fountain lighting voltage is limited to the use of 12 V ac.

Third, the standard requirements for lamps

1. GB of universal protection requirements 16895.19-2002

Can be seen from Table 2, GB 16895.19-2002 for lighting protection requirements are as follows:

Zone 0: protection requirements lamps using a power supply voltage and operating voltage not exceeding 12Va.c. or 30Vd.c., shell protection grade IPX8.

(3) shall comply with the requirements of IEC 60598-2-18.

3. GB of safety requirements 7000.218-2008

GB 7000.218-2008 provides swimming pools and similar fixtures with safety requirements, standards regarding lighting classification requirements are very important.

(1) Type of protection against electric shock

Lighting should be protected against electric shock Class Ⅲ lamps, its external and internal operating voltage line should not exceed 12V (12V ac new standard or refined as 30 V dc).

(2) lamps dust and water categories

- Lighting and pool, that part of the water tank is pressurized classification should contact watertight (IPX8);

- Lighting and pool, water tank is not in contact with that part of the classification should be at least as dust and splash-proof (IP54).

(3) The luminaire installation, replacement and power connections in the form of light

-A Category: Power connections and replacement of light fixtures on the side not in contact with water;

Class-B: part or all of the drained pool water, the water from the side in contact with the lamp replacement light source;

-C class: Remove from the water after replacing the lamp light.

Fourth, the other electrical devices required

Of course, swimming pool, LED commercial lighting wholesale is a system problem, not only with lamps, but also with other electrical devices exist about, except to meet general requirements in Table 2, the wiring system, junction boxes, as well as switching and control devices placement, GB 16895.19 and the corresponding IEC standard requirements are related to the latest version:

1. Switch control means or socket

Analysis the present situation of LED flat panel light

With the improvement of people's living standards , people are increasingly demanding indoor lighting , not only reflected in the quality of products and energy , a sense of beauty and fashion lighting design also a factor for consideration . Unique LED Panel Light SMD LED as light source, light guide plate and add ( or ) the diffusion plate , so that uniform illumination , its slim design can not only provide lighting , and add artistic beauty, very popular in recent years .
Currently the main use of LED panel light occasions office lighting, classroom lighting, hospital lighting, hotel lighting , can also be used in showrooms, such as the family living room , decorated environment and create technology and fashion sense . At present , the main competitor for the LED panel light source based traditional fluorescent T5, T8 Grille , or is the LED light source with a hanging wire grille and office type lamps . But the price of LED panel lighting wholesale is much higher than the grille , almost line type lamps hanging close to the overall competitiveness of the market has not been fully reflected. According to the State Lighting R & D and Industry Alliance statistics , in 2010 China's LED flat light output of about 800,000 , the overall market size of nearly 600 million yuan , the proportion of exports in all kinds of lighting lower , about 36.8% , the production company focused on Shanxi, Guangdong , Shanghai and other regions, the combined effect of a larger industry . Volume production and application of LED panel lights are still small, has not yet formed a more consistent product specification form .
One , LED panel light classification
Depending on the classification, can be " nominal" to make the following classification for the LED panel light lamps on the market:
- By shape : LED panel light can be divided into squares, rectangles , circles, and other foreign inner circle ;
- By Size: Lamp size has to do around the grille to replace the grille for the purpose of 300mmx300mm, 300mmx600mm, 300mmx1200mm, 600mmx600mm the LED panel light ; there are alternative downlight 2 " , 2.5" , 3 ", 4 "and other LED panel light ;

Second, LED panel light advantages and disadvantages of
Direct- plate light relative to the side plate light emitting has the following advantages: First , high energy efficiency . The light emitted by the LED diffuser plate out of direct sunlight , improving the energy efficiency of lighting systems . According to reports , there 80lm / W or more products . Second , the cost is low. Eliminating a light guide plate to reduce the cost , the cost of such lamps , a large space inside , the design is more flexible. Third, reduce the lighting quality , because eliminating the light guide plate . Fourth , increased reliability . We know that in lighting design , the various components and properties of the materials used to determine the performance of lighting products , components increases, reducing the reliability . Therefore, if the diffusion plate using better quality , to ensure longer lamp life, and the light guide plate and the reflective film at high temperatures , yellow easy to aging effects of light efficiency and life. Direct- flat major downside is that the light can not be made too thin. Cost to have a certain pitch , otherwise LED lamps produce light diffusion plate between the highlights , which will inevitably lead to increased thickness of the lamp , the lamp housing followed increases, the appearance will seem poor lighting , and the thickness increases , the increasing the light transmission path , the energy efficiency of the lamp is reduced. Since the lamp beads are fixed on the rear panel , if the back with a whole piece of aluminum plate , then the cost will be high , if the strip of aluminum plate , fixed and positioning is also a problem. If the rear panel of the use of direct- plate lights Omo aluminum , but also consider long
Back issues after bending deformation time lifting.
Table 1 of the same side- power LED Downlight flat performance compared with conventional LED Downlight
LED flat panel downlight
Side plate lights shortage mainly :
First , energy efficiency is not very easy to do . Table 1 shows a comparison of the same power side LED Flat Downlight LED Downlight with traditional performance . As can be seen from the analysis, the same power side LED panel light on the light output , energy efficiency and color rendering index (CRI) and other performance indicators compared with conventional LED downlights still not a small gap.
Second, the high cost price . The light guide plate is the core of the side- plate lights ; due to the increase of the light guide plate , the price is higher than the direct type ;
Third, the high quality requirements for light guide plate , if designed properly, will appear in the middle light , dark sides , or into the light side of a bright side , or different angles brightness inconsistency phenomenon, affecting the quality of lighting .
Fourth, the reliability is relatively poor. Since the flat side of the light guide plate lamps , reflective film reflective inks and always at a relatively high temperature , it is easy to turn yellow aging , resulting in a light rate decreased greatly reduced lamp life .
Three , LED panel light Prospects
LED panel light though a good glare control , light uniformity , and many other advantages , but to replace LED panel lighting wholesale  also address the following questions:
First, the performance is low. For side LED panel light , low performance is still a problem . On the one hand , to achieve high brightness , the number of chips to be increased to improve the power saving effect , but does not reflect , in particular, large-sized flat lamp ; other hand , the power increases , the lighting apparatus of the LED module in the operating temperature will increase, the impact bad light and life, so how to deal with balance " thin" and " energy efficiency " between a problem.
Second, the price is high. To improve energy efficiency , LED quantity needs to be more , costs are increasing at the same time , it also brings how to deal with the heat. Meanwhile, the price is cheap and efficient light guide plate , compared with the traditional grid does not have to replace the price advantage. Moreover , with the light guide plate lights do cost a bit expensive , short-term consumer is difficult to accept.
Third, the maintenance easy. Unlike traditional fluorescent or LED Grille Grille , if the light source is broken, need not be very professional people you can easily replace one , while the LED panel light , if the light is insufficient or not bright colors may have to replace the entire luminaire , and those who need to come to a very professional operation and maintenance costs do not say , mainly too much trouble .
Fourth, public awareness is not enough, will inevitably affect the sales market. In addition, in the end what can be called a flat light fixture , the current lack of a unified identified . There are lights on the market called the flat , flat lights, panel lights , and some people believe that the outlook for flat planar light fixtures called flat light . In accordance with National Semiconductor Alliance "LED Panel Light ( a ) performance requirements" as defined in the draft : LED panel light : one to use as a surface emitting LED light source and lighting , lighting maximum thickness and smooth lines of the ( rectangular or square lamps the longest diagonal of the circular lamp diameter ) ratio of between 1 / 10 to 1 / 30 of the LED lamps. If you follow this definition , many LED downlights , LED fluorescent lamps with LED panel light and so become , it is unscientific .
Accordance with the " Indoor LED lighting technology specification - Part 2 : Flat Light" ( Shenzhen LED Industry Standards Alliance standard ), LED flat lighting is defined as : LED light source through the appropriate optical components to meet the needs of even the light from a plane device issued , according to LED panel light did not reflect the luminous characteristics. Common standards across the Taiwan Strait , " indoor general lighting LED flat lighting " in the definition LED flat lighting more accurately reflects the characteristics of LED flat lighting , but requires "total thickness not exceeding 70mm" can really be qualified to distinguish between traditional LED downlights and LED flat Down still open to question . Currently there are some phenomena mentioned plate lights , and asked how thin thickness or how high performance LED lamps have just before setting off on the performance of the domestic market, " vicious " race , as if LED panel light only by the performance indicators degree of thickness or performance indicators to determine the level of the individual , which is not desirable.
I personally think , LED panel light should not blindly pursue thickness design , and give up the characteristics of the product itself , shall be based on the safety of products , color quality , suitable brightness , light distribution , glare control , appearance , maintainable , price, comprehensive energy efficiency indicators for evaluation. One-sided, single indicator study may lead to market disturbances and reduce the reliability of the overall quality of the product , dampen consumer confidence. And LED panel light thin and can not do and then do better than thin oled lighting products , LED panel lights should therefore use LED own characteristics and advantages, to meet the practical needs and maximize energy efficiency under light premise of luminaire slim , personalized design , so as to occupy a place in future indoor general lighting and commercial lighting market .
