Commercial and high-end residential swimming pool lighting design

With the continuous development of led street light wholesale technology, lighting pool is becoming increasingly attractive and interesting. Because the color temperature of the LED light source rich, RGB or RGBW flexible control, coupled with its energy-saving long maintenance cycle, LED pool lights now popular.

So for today's pool lighting, what should we consider when designing it? Today we'll discuss a few points:

1, considering the overall environment surrounding light, not just design the pool itself

First of all, the most important but often forgotten when lighting is designed to pool forget to consider the overall environment surrounding lights, just design the pool itself.

Why should we consider the overall? One reason is that the brightness of swimming pools and to be able to match the brightness of the surrounding environment. This is also a safety factor, such as lifeguards often complain Ceiling reflection in the water caused great glare.

We need to keep in mind three important functions pool lighting: illuminate the pool floor and side walls, objects illuminated swimming and water, and the water itself illuminate certain glare effect. Finally, an implementation requires a small water particles or air bubbles, the light can be emitted in the above irradiation.
1 Pool Lighting

Figure: In this case, the pool lights need to be able to catch up with bright ambient light, so a lot of the number of pool lights. Because ambient light indirect lighting, greatly weakened the glare on the water flood and produced. In order to allow more uniform illumination swimming pools, pool lights beam angle of about 90 degrees.

2, should be considered in the pool design stage lighting design

The second important factor is the lighting design of the pool should be in the pool on the early stages of the design into account.

When watering down the concrete pools, while the lamp does not go into the embedded parts, then it is difficult, you need to drill a hole in the concrete.

And does not recommend the pool surface mounted lights in the public swimming pool, because it is easy to be damaged.

Pool lighting maintenance is very troublesome, it is necessary to use good quality fixtures, and long-life light source, not to mention the IP rating must reach 68.

3. Other TIPS Pool Lighting Design

1) installation depth

Depending on the depth of the pool and lighting beam angle, lighting installation depth is usually 600-700mm, some shallow children's pool at 400-500mm.

Remember, only the light shines on the water - the water will be reflected back to the time when the incident angle of the air interface is less than 41 degrees. If the installation depth is too shallow, light shine before the water body (eg swimmers) went on the air to escape the water to go, looking down from the water, there will be a lot of dark areas underneath the lamp. If installed too deep, you will see there is a bright spot beneath the glare of the lights, when the swimmer when lighting fixtures will be close enough.

2) lamps with light

Taking into account the light distribution problems, we need to think clearly is a need for a more uniform illumination, or some kind of accent lighting, or both.

Most underwater lights have 10 to 90 degrees different beams, and some have "Multiflux" Multiple light distribution means, such as beam angle 120 is 30 degrees, but the center of a narrow light. For less than 1.5 meters of shallow pool, it is recommended to use an oval light distribution, such as 15 × 40 degrees, so to avoid glare and optical loss point.

3 underwater lights
Figure: a large swimming pool using a 90-degree beam angle underwater lights, installed on both sides of the cross, more uniform illumination.

3) dimming control

Pool lighting dimming rarely needed, unless it is used with a fixture in all places, but do not need 100% of brightness in some places. Whether in the design and selection dimming lamps need to be considered when.

But many times the pool will need to be able RGB or RGBW color tone, this time you need a good controller, such as DMX control. If you want both a good color effects, but also very positive white light, then they would use RGBW LED lamps, so as to individually control the LED RGB and white.

Most of the swimming led street lighting fixture, users prefer only one controller, there are several good set static or dynamic scenes, each scene can be controlled and adjusted individually. There is a scene when the pool and surrounding environment set lighting scenes together.

Treatment 4) other water elements

Many times there are other pools of water design elements, such as drowning, or water, or water fountain. Do not forget to add lighting effects to them, such as adding or their rear lights from the bottom of the pool.
Treatment 4 other water elements

Figure: Somewhere very beautiful water element, surface-mounted LED floodlights are installed behind the curtain of water.

5) deal with the special needs of the pool

Finally, there are some special needs swimming might want to consider. For example:

Small decorative LED point?
You can move the floor?
Flush mounted or flush mounted but need a very thin donut?
High bit salty pool? Lighting needs to 1.4539 stainless steel alloy lamp body in order to better prevent corrosion.
Or sometimes may need to replace the existing old to the new LED lighting fixtures?

All in all, a satisfactory pool lighting design, the design of demanding, the need for adequate consideration. At the same time, you need a good quality fixtures, lamps flux, size, color, color temperature, the beam angle, etc., need a good match.

Shortcomings of the led lighting design in China

During the International Conference on the implementation of special lighting design is very rare thing. Let each country representative for China to see the lights is to emphasize a sense of presence of China in the international arena important means. led high bay light for sale can be said to cast light on the traditional use of the building and the use of colored lighting is more Chinese style lighting methods.

Facilities for landscape is likely to give people cause temporary decorative festive activities such misunderstandings question, share with us his views:

Cast light itself at night to contain particular stimulus factors. In shopping malls and other places, sometimes bright lighting design highlights the lively atmosphere, but in a number of government buildings and airports and other places, there is no need to be so bright.

Conducted according to the purpose of lighting design, I think it can be avoided and cause misunderstanding, for designers rational design is necessary.

Also in the travel program or other TV shows look at some foreign lighting design case, then lighting design considerations will also change. Lighting in the near future will also become a symbol of the presence of the background, as the same clothes infiltrated into normal life. Ten years later and now will have a completely different picture.

Cities tend to be too concerned about the lighting effects lighting, functional lighting and the city did not get a reasonable implementation, how to balance the relationship between what the think?:

Traditionally, landscape lighting, lighting design to be based on ensuring the safety of the building's lighting design should consider its aesthetics. In fact, we need to consider these two ideas together. Considered separately, then the effect is mostly designed unsatisfactory. Sometimes too bright, lighting design becomes wasteful, and sometimes it is too dark can not ensure safety.

My lighting concept is to achieve the best lighting effects with minimal lighting. Lighting design has been always using the program to meet these two conditions, carefully try to speculate in the design, so that the overall effect is to achieve the best results.

Taking into account energy conservation, there are many arguments for landscape lighting, landscape lighting needs because consume a lot of power, but for a city in terms of landscape lighting is a manifestation of the city where a sign of prosperity, then landscape lighting can do both saving and gorgeous ?

I saw the Chinese buildings, sometimes feel too wasted electricity. For example, in Paris, in addition to historic buildings, the law prohibits the use of cast light lighting techniques, we can say now saving mankind should become a concern.

China on energy saving and environmental pollution problems if the people raise awareness, I think the concept of lighting design will change. Although the use of LED and other energy saving lighting and strong on the method will be very helpful, but a clear distinction needs to use the projector without the use of light construction and building flood light is also necessary.

In places such as commercial facilities need to use lights lively atmosphere to attract customers economic prosperity, using historic buildings tourist area lighting allows visitors to gather, these can be carried out. But in places such as hospitals and offices were pretty even and beautiful lighting design also can not wait any economic effect.

I think all of the lighting design for the city need to consider the overall effect, but also need to consider the purpose of the lighting design. In addition to saving aspects, lighting designers need to carefully consider the lighting design. In Japan, there are a lot of past energy crises arise, every national idea will change. Although we do not want to have a crisis, but I think China will change much in the near future consciousness.

The idea that the night lighting Night should make people feel comfortable, quiet, gentle, quiet, but some of the city landscape lighting feels "dry", "seek", which, in Chuanzhuo Shi said:

Europe cast light on the buildings, most of the buildings in order to highlight the features and looks beautiful at night, but the Chinese consider when lighting design, the appearance of the most concerned about is not the building, prominent eye-catching is the mainstream of China's lighting design .

Lighting has a tendency to representatives of national cultural life, countries are not the same lighting requirements. However, the Chinese lighting design when considering the need for a quiet atmosphere to distinguish between places for lively atmosphere of the place. This is not only related to the appearance of the building, but also to consider the purpose and location of the base itself on building sites, conduct appropriate lighting concept design.

Such as led street lighting Manufacturer (department stores, etc.) need to be considered when designing bright and lively atmosphere, the opposite of the traditional buildings and government offices in these places, etc., need to focus on the quiet, solemn mood lighting. I am opposed to the use and daytime bright lighting design in the same night.

I design for lighting at night, has been focusing let people experience the night lighting effects and style consistent.

LEDs Magazine celebrates tenth birthday milestone

When the first LEDs Magazine newsletter was sent in late November 2004, it created a stir in the LED industry. LEDs Magazine was the first publication focused solely on the applications of high-brightness LEDs and the technology of building LED-based systems. At that point, LEDs were discussed from a technical standpoint in semiconductor magazines, and treated as a little-understood novelty by lighting publications. led high bay light supplier served to bridge the gap between the semiconductor and lighting worlds.
One of our first articles discussed a US-based manufacturer of LED chips and silicon carbide (SiC) wafers that had recently unveiled its first packaged LED product. The new XLamp product from Cree Lighting was a cool-white model rated at 30 lm at an input power of 1W. These values help to explain why the lighting world was yet to take LEDs seriously.
Another article in the first-ever LEDs Magazine newsletter was a report entitled "Brussels conference sprouts better understanding of LEDs." Among the many issues discussed were the disconnect between what LED producers were delivering and what the lighting companies required; the lack of standardization; the mis-selling of LED technology as an answer to every lighting situation; issues with binning and lifetime; and providing LED data in a format that the lighting industry could understand. Ten years on, progress has been made, but some of these issues still remain.
A third article demonstrated the standard of reporting that is still a hallmark of LEDs Magazine today. The piece entitled “Patent issues cause discontent among LED lighting manufacturers” was the first in-depth coverage of the patent lawsuits between Super Vision and Color Kinetics, subsequently acquired by Philips.
Alongside its editorial coverage, another unique aspect of LEDs Magazine was its publishing model. Initially, led high bay light for sale was entirely digital, with a website and email newsletter. When the first magazine issue was published in April 2005, this was only available as a PDF download. Later, in February 2007, a print version was produced for tradeshows and for paying subscribers. Today, over 70 magazine issues have been produced by the LEDs Magazine team, along with around 500 weekly newsletters.
LEDs Magazine’s founder and former editor Tim Whitaker provides a retrospect of LED industry coverage and the evolution of its media partnerships upon the tenth anniversary of the magazine’s debut.Acquired by PennWell in May 2007, LEDs Magazine now benefits from close interaction with market-research firm Strategies Unlimited and the Strategies in Light events (including The LED Show). Add to that the recent partnership with Revo Media, and we can all expect LEDs Magazine to go from strength to strength in the next ten years.

Cooper brings WaveStream planar technology to round LED pendant

Eaton's Cooper Lighting division has announced the Portfolio Surface-Mount LED-based luminaire that incorporates the company's WaveStream planar light-guide technology. The fixture surface mounts to standard or high ceilings including applications with little or no plenum place, in pendant and other configurations.
Cooper brings WaveStream planar technology to round LED pendant
Cooper had been proliferating WaveStream based on light-guide technology licensed from Rambus. Cooper first demonstrated products at LightFair International in 2013. The technology relies on led high bay lighting wholesale to edge light the optical guide that embeds miniature beam-control elements that Cooper calls AccuAim optics. In simple terms, the planar guide produces uniform diffuse light with minimal glare.
Cooper has used WaveStream in a number of ceiling troffer-style fixtures, some of which dramatically expose the light guides. But the presumably premium-priced technology is also finding use in surprising places. For example, Cooper announced a WaveStream-based parking garage fixture a year ago. More recently, the company also deployed the technology in downlights.
Given the variety of WaveStream-based products, it comes as no surprise that the technology has come to a round solid-state lighting (SSL) flush-mount form factor. The product mounts directly to a junction box. Cooper offers models ranging from 4500–9000 lm, 4000K–4000K CCT and 80 or 90 CRI.
"The Portfolio surface-mount product offers customers a high-performing, versatile luminaire," said Mark Eubanks, president of Eaton’s Cooper Lighting Division. "The luminaire’s superior optical performance, low power consumption, low life cycle cost, multiple mounting configurations, and architectural design serve as an ideal solution for both retrofit and new construction opportunities, as well as those with limited plenum space or hard to access areas."
Cooper is also supporting smart-lighting installations with a variety of control options. The standard led high bay light for sale includes 0-10V dimming support and can work with trailing-edge phase-cut dimmers such as those designed for electronic-low-voltage (ELV) products. Optionally, you can add support for DALI (digital addressable lighting interface) networks.
The product also offers flexibility in terms of mounting options. The version pictured is the standard pendant mount. But you can specify suspension by aircraft cables, surface mount direct to ceiling, and even wall mount versions. Finish options include white, black, bronze, and silver.

What can we do for the LED lighting industry?

Under the LED lighting industry and constantly improve the policy environment, the continued growth of industrial scale, independent innovation ability to rapidly increase, applications continue to develop the background, we see the LED lighting industry increasingly bright future. 2015 is like the wind, the waves came. Premium Shi Yin Kang Optoelectronics Technology (Shanghai) Co., Ltd. Managing Director on the status of the industry, light industry enterprises on how to get through the "winter" and other issues were discussed with the author.

I asked: Do you think the current led high bay lighting wholesale is kind of a situation?

Subject to technical improvement and rapid price drop impact, while the pattern of change in the industry, the price gap with the traditional lighting LED lighting products are also among the shrinking popularity of LED lighting products, has become an indisputable fact. Some time ago, LED lighting market has undergone a lot of unexpected events, both internal and external to the outbreak of blowout, this is a wake-up call to the industry knocking. Hard enough, there is always the possibility of being eliminated; without knowing, eventually unexamined, by dragging the industry forward. We must be constantly vigilant, present and future, what do we do? What can we do? What are we going to do?

Important than seize the opportunity to grasp the trend. Lighting industry is a promising industry, in the current market situation, who first discovered and developed to grasp the dynamic trend of the industry, then who could rewrite the rules of competition of the industry, to promote the industry reshuffle and upgrades.

Second question: How Will the lamp prices low profile in the industry, "winter" Premium Shi is how to do??

"Separatism with potential"

All along, we are accustomed to the "winter" as a metaphor of the lighting industry is currently enjoying a period. In fact, "winter" is not terrible, terrible is the self-wrapped solid, no action. Premium Shi lighting is selected in the winter self-cultivation, hold the pace, stability and development. Premium Shi is how in the winter of self-cultivation?

First, rational use of resources, compress product cost, do not blindly expand business scale and capabilities, plan and moving; second, to increase the pace of independent research and development, in the lighting industry, product homogeneity serious, copying each other counterfeit abound, we take this opportunity to rest, careful research and development of new products, cultivate core products with market competitiveness. Third, reasonable quote highly qualified personnel, operating business is business people, promote innovation and talent introduction mechanism, the establishment of their talent, only the best talent management mechanisms used for the "winter" after takeoff reserve enough talent.

Winter will allow the market to rebound any time feel spring-like warmth, but that does not mean that spring is coming. Macro side effects, on the one hand produces immediate boost; it also needs to be in time, in order to gradually feel substantial stimulus. In the current market environment, should not be too pessimistic, should not be too optimistic, but also must not impatient, have a normal state of mind and plenty of patience, waiting for the arrival of the warm sun, absorb nutrients.

Three questions: What do you think the current core lighting business which is the primary consideration of factors why??

"Commandeered the people"

Market demand pushed the speed of the development of LED lighting from the roots. Many companies have vied for the led high bay light manufacturers, to compete in this huge cake, various warlords fighting, competing, out ...... inevitable. Which companies holding a trump card, the more the greater the probability that the odds. Which I must mention is that - talent pool.

Enterprises lack the reserve personnel, after the important positions successors, job vacancies available without super sub, which are fatal to enterprise development. Thus, the construction of the talent pool mechanism, create the future competitiveness of enterprises is particularly important. If the "hero", then today's talent has deservedly become the lighting, "Hero" under the current situation.

2014 draws to a close, the upcoming 2015, Shi deeply privileged "strategic position" comprehensive investigation and eventually a new round of programs to potential separatist, dominating people, privileged official is ready fully prepared, just waiting to bloom!

Interpretation of 2014 development of five areas characteristic of LED lighting industry

2014 has gone into the final month of the year to show how the LED industry characteristics, we analyzed from five segments.

2014 Annual LED display areas showed the following characteristics:

In the first half of 1,2014 China led street lighting fixture market changed little compared to last year, business orders is relatively stable, but many SMEs profit in low-profit status, and the payment of prevailing difficult problem, "triangular debts" is still the LED display industry-wide problem.

2, new market segments LED display enterprises become a new growth point. Outdoor advertising media, indoor small spacing and other market segments remained good growth, making the LED display industry to maintain a certain growth. Lehman Optical layout as sports media fields.

3, LED display of "small time" - a small pitch LED screen. The world's leading LED manufacturers began competing to launch their own small spacing strategy, at home and abroad also small LED spacing prospects of this product very promising. Among them, high-density fine pitch LED display is an important industry in emerging markets, but also one of the higher-margin products currently on the market.

LED lights in the field year 2014 showed the following characteristics:

1, LED street light overall environment stabilized, but due to the change of government, the impact of corruption and many other objective factors, LED lights this year to promote the speed significantly lower than expected, the growth rate slowed, showing enough to go around the situation, the market is more rational.

2. Overall, LED lights this year in terms of overall road illumination, uniformity and glare control have made great progress, but because of market demand and tight LED lights manufacturers led to fierce market competition, the huge base, LED lights are more concentrated in the size of the order larger enterprises, the future of LED lights manufacturers in addition to the quality of the fight is that price, to seek new economic growth point is the goal of all manufacturers of LED lights.

3, LED street light structural design changes, the light source module of the new trend of the future. Previous monolithic and modular design costs if there is a problem lighting the whole lamp must be replaced, but only after you replace the light source modular electronic control part, it did not cost savings, although the perspective from a single lamp, but in the long run lower.

4, intelligent control systems used in the LED lights gradually increased, many foreign companies are committed to smart LED street lights R & D, such as Philips, GE and other international giants, Kingsun, Optronic other domestic comer. Intelligent LED lights can be technically original LED energy saving of 10% -20%, but the lack of stability of intelligent LED street light system, the failure rate has doubled over the original system may be bad even faster than light.

2014 Annual LED chip / wafer areas showed the following characteristics:

LED chips in the first half of 1,2014 growth trend continues at the same time, the concentration of LED chip industry increasingly high domestic LED chip factory polarization increasingly serious.

Two to three optical and headed inland led street light with solar panel, wafer plant rise, domestic LED chip has gradually gained acceptance in the local market, grab the original units produced LED chip market share in the mainland market.

3, LED chip design and manufacturing to the "small size, high current, low voltage, high lumen" direction, the same efficiency, but smaller, or the same size, higher luminous efficiency.

4, limited market capacity determines the shift in the relationship between enterprises. Currently LED industry from epitaxial silicon to the package until the downstream applications, the overall overcapacity situation has not changed, China's chip market is still digesting capacity.

5, LED listed companies have released three quarterly in 2014, the first three quarters of this year, more than 50% of the LED chip factory to get success, the list polarization LED chip companies, expects LED chip plant in addition to the top three, the market position will change.

LED light source in the field year 2014 showed the following characteristics:

1, LED fluorescent tube, bulb became the highest-selling LED light source of the top two. China is the world's largest lighting production, sale and use of the country, China efficient lighting products accounted for more than 80% of global production. LED bulb market will maintain rapid growth trend.

2, LED fluorescent tube, light bulb and other conventional products to maintain the price trend in the next two years will be a fierce price competition. Expected by the end of 2015, with the luminous efficiency of LED energy saving lamp price and the price of 1: 1 ratio, costs and prices continue to maintain a 30% decline.

3, LED light source in the electricity business sales channels increasing, more and more manufacturers to develop LED lighting electricity supplier.

4, LED light source to intelligent lighting direction.

2014 annual drive power areas showed the following characteristics:

1, LED lighting drive power growth. By the end of 2013, the number of Chinese LED driver power supply over 400 businesses.

2, grow larger, but the gross margin continued to decline. Some of the power companies lack the power to release the results, LED lamp power more competitive, which some companies are seeking transformation.

3, the market need for high-quality LED driver power supply products. In foreign countries, customer LED drive power conversion efficiency, effective power, constant current accuracy, power life, electromagnetic compatibility requirements very harsh; in the country, but also from the previous low-end power supply market price competition gradually shift the demand for more high-end brands.

Additionally, from September 1, 2014, LED driver power supply included in the scope of compulsory certification 3C, 3C certification of the execution time is September 1, 2015. Be included in the national compulsory 3C certification system, which means that the LED power companies must meet in order to go on sale 3C certification standards, rules and practices of the errant companies will be a hit.

4, LED power supply modular and intelligent to be a trend in general lighting. Modular LED power costs will be lower in the future, intelligent to meet the needs of people's lives, such as dimmers, thermostats, etc.

Light industry development has some controversy

With the development of the lighting industry drifted further away the golden period, in such a period, lighting companies in order to achieve lasting momentum must be two-pronged approach, giving equal importance of the company's marketing strategy and business management.
Lighting industry prospects deposit dispute

In 2014. This year, the led high bay light manufacturers experienced a dull gold, nine silver ten, experienced an eye-opener for the electricity supplier channels. However, there are still many lighting companies not complain, complain that the market is poor. Insiders pointed out that this is an excuse to their business. "Even the best of the market, we have also seen the closure of business, then the bad market, there are a growing business. You say the environment is not good, why there are so many other industries involved in the lighting industry? You say bad lighting industry do, why the number continues to increase brand lamps. this phenomenon indicates that the series compared to a mature industry, light industry is still good to do, but not everyone can do it! "It was the best of times, it was the worst era, this is the best time lighting business bigger and stronger.

Lighting companies ignored the company's management

Lighting market environment is really depressed it? Insiders pointed out that, in addition to large environmental impact, the excess corporate marketing, business operations and management of a problem. Lighting industry, many companies over-reliance on certain marketing tool, while ignoring the enterprise operations management whether health problems. "Marketing a fresh recruit, wanted to eat around the era of days gone past business, put forward a casual activity, you can make money. Invincible marketing tool does not work now, and this under the enterprise on the ignorant the example price promotion, is a harm than good practice. "

Insiders stressed that "a lot of lighting companies in marketing, management defeated in marketing era of excess, if lighting companies simply play marketing, management ignored, and that is a dead end." That being the case, then how specific lighting companies to do this? the source stressed that address future market, and only return to nature, pragmatic development, and no other way. The first is the focus on the present, the led street light Manufacturer of the job done. Establish good business operation and management system, and this system is not rigid, to be matched with each other and the moment people, and things, in order to play each other the best of force, so that enterprises to enter a virtuous circle. The second thing is the layout of the future, do disruptive innovation.

Lighting companies in order to grow, business management is very important. Only lighting business marketing strategy and business management to do, in order to enhance the competitiveness of enterprises, but also to identify the path to success.
