LNG natural light — LED outdoor lighting kits decorate TOWNS

China’s ancient architecture is a form of Chinese culture. It express the meaning of its specific historical background. How to change the hundreds or thousands of years, we can just through the day to watch the scene of led outdoor lighting kits, so that they can bloom at night. A unique visual appeal of LED Street Light has become a major issue in the urbanization process.

The Qingyan city with 630 years of history now Huaxi District qingyan town, located 29 km of the southern suburbs of Guiyang City, built during the Hongwu 11-year (1378), which is now one of the Guizhou provincial cultural towns, history long-standing cultural atmosphere, and extremely rich cultural atmosphere.  The ancient town of three square km radius within Ciyu buildings of  led outdoor lighting kits, built 9 Temple 8 Temple, Court, Temple, a hospital, a palace, nearly 30 temples, ancestral halls, many of which are still preserved intact. Rational layout of these ancient buildings, imposing, richly ornamented, double eaves and fly, building technology exquisite of LED Down Light and breath taking.

So grand and magnificent architectural complex, what will happen in the sun and night? Night lighting of ancient building to highlight the advantages of the ancient city,  played a night view of the unique rhyme charm. With the development of China’s urban landscape lighting and tourism, the architecture of night landscape being valued increasingly subject to the attention of all walks of life. Night become a prime time for people’s entertainment. Good lighting night image and the artstyle of the display for led outdoor lighting kits are ancient buildings important tool.

At night, Qingyan ancient city was ablaze with LED Street Lights. Visitors can not help but wander, and enjoy special melodies in the shuttle of the light. Chen Huijun natural Opto electronics Technology Co., Ltd. in Huizhou City Director of Sales in charge of the old town of outdoor lighting, who will usher us to oversee the city. “LNG natural light” brands of LED tiles lights, wall light are a total of 7,000 lamps, underground lamps, Spot lamps and other lighting, engineering capacity, and the most challenges is that it is necessary to spend a lot of manpower and resources, more challenging have been thinking about how to use functions of these buildings, the architectural style, structural features, finishes, materials, decorative patterns, as well as building an environment in which the focus of part of the outstanding lighting, not only finding the key part, but also take into account the overall effect, and only design so many dimensions of lighting can we see a classic art style.

Modern lamps from the lighting effects, not only in the living room is also an important component to create the atmosphere of the indoor environment. The indoor lighting can not be separated from the lamps, lamps will crafts reaction, it is both a tool to stop the transfer room install effect, set up the visual conditions, and is part of the decor of the room, lighting skills and install art concession body. Then you would ask, where to get led lights?

Coordination of lighting design and light color, make the indoor environment certain atmosphere and mood, reflecting the style and characteristics has always been, an increase in the erection of the beauty of the art indoor space more responsive to people’s psychological and physical in nature, needs and aesthetic fun.
LED is a green light. DC LED lamp driver, no strobe; no infrared and ultraviolet components, there is no radiation thick cloud, high color and high power LED; dimming performance, and visual color temperature change will not survive abuse; cold light low heat, never mind peace touch; these are the traditional incandescent and fluorescent tubes reach. It can supply very calm and light space, but also a good decent people only tough management needs is tough to protect vision and environmentally friendly light source.  As a new type of LED lighting lighting products, its application vision of world attention, high-brightness high-power white LED known as the most valuable source of the 21st century, will cause a new revolution within the lighting. where to get led lights?

Since the emergence of white LED luminous principle or efficacy of other strengths unmatched by other conventional light sources, LED Tube Lights has become the 21st century a trend of the room lighting, LED and incandescentfirst appeared as The room lighting has opened a new heaven and earth.

LED component materials, LED cold light source, semiconductor lighting for the environment is not to thick cloud, compared with incandescent, fluorescent, energy-saving effect does not matter came to more than 70%. At the same brightness, power consumption is only 1/10 of the subtractive incandescent, fluorescent tubes 1/2 if 50% of the LED Replacement Lamps (where to get led lights?)to replace our existing lighting every year our frugal electricity commensurate with one of the Three power plant the sum of the generating capacity.

Future of white led bulb

LED lighting will  obviously replace incandescent and FL/CFL
Lighting (white led bulbs), the LED Street Light driving force behind are government regulations, high efficiency, long life and environmental issues.

The only remaining option is to contain a trace of mercury in CFL bulbs and LED bulbs, but not fortunately, the cost of led bulbs is still much higher than incandescent or the CFL. However, achieving this goal by major companies to promote, such as: IKEA announced they will start phasing out incandescent bulbs, the future supply CFL and LED bulbs. Another point to note is

LED prices will come down slowly, in order to effectively reduce the price of the total LED light bulbs. This so that consumers can use a longer life

As the LED accelerated pace of bulb replacement, we can foresee the future more features will be built in these bulbs, the will to change our daily lives.

Benefit from the LED lighting is not only the home market. According to a report written by the U.S. Department of Energy in 2008, if all U.S. retail providers have switched to LED Flood Lights systems for refrigerated display case lighting,  they would save save 2.54 billion kwh of electricity, which equates to a saving

273.8 TBtu of energy, equal to four large-scale thermal power station of coal a year, or more than two million families a year of electricity consumption.

Lighting trend has been going on for some time, many large retail companies is the gradual introduction of LED lighting, such as: Wal-Mart 2009 Announced in December in the 650 stores with LED Replace (white led bulb) the ceramic metal halide lamp; before the end of 2010, a showcase of over 500 stores to switch to LED lighting, in order to achieve an annual energy saving 1600 Million kilowatt hours of goal. SuperMax is in Puerto Rico with LED Lighting technology, to replace all of its store lighting.

In the UK, Sainsbury’s has installed in all of its UK stores over 15,000 refrigerated display cabinets in use LED lighting systems. In addition, the outdoor and infrastructure markets from the traditional lighting of LPS, HPS and mercury vapor transfer to the LED lighting solutions.

LED Tubes have many advantages, such as: adjustable brightness, transient conduction (no warm-up time to achieve maximum light output), and low maintenance. In the world are carrying around a number of innovative pilot projects, to upgrade the parking lot lighting, street lamps and traffic lights.

Europe’s goal is to reduce energy consumption by 2020, 20 percent, the European Commission in February 2011 announced a plan designed to raise a
10 million euros to implement two to three large projects, demonstration of LED lighting (white led bulb) in the light quality, low-power, low running costs and user acceptance.

Future of white led bulb

To speed up the LED promote the use of lighting in general lighting market, we need to realize three important technological breakthroughs.

First, you need to reduce the cost of the drive can be achieved in the mass consumption of the general lighting market, LED bulbs and lamps. The number of LED chips and the power Source IC Suppliers are studying how new technology or improved technologies, little by little to reduce the LED chip or driver IC Cost, the purpose is to lower the price to provide higher efficiency.

 

Popularization of types of LED lighting in 2015

Upstream and downstream the organization ZHAGA, international leadership factory series of LED lights, types of led lighting engine interface standard. International Lighting Fair in the second quarter can already see the finished product. Epister Chairman Li Bingjie pointed out LED light source for lighting design bring a new look. The international interface specification is determined, LED lighting replacement faster, it is expected the popularization of LED lighting of the 2015 ZHAGA interface.

Li Bingjie pointed out Frankfurt show is the most splendid show in these several years. To let LED temperature, energy saving, thin features, and present a new lighting appearance, stimulate many exhibition building designers. We believe that the future of types of led lighting will have revolutionary change.

ZHAGA LED street light engine have been released interface standards this year,  Li Bing jie said, the ZHAGA lighting module finished exhibitors in lighting exhibition site, which will contribute to the replacement needs of the future of types of led lighting. Li Bingjie said that the architectural design in the past alloyed the LED  lamps because they want to look varied. Because of the different specifications, the designer and the user is difficult to replace the light source in the future,  but now with the born of the interface standard for LED lighting , including the outdoor street lamps, tunnel lights of the infrastructure, indoor general lighting can be applied.

New era of LED lighting, not just the interface changes to lighting but more design sense of the future.  Li Bingjie also pointed out that future consumers will be educated to purchase the lighting who are not just to see the wattage, but to learn the “lumen optional LED lighting brightness you want.

Quarter of this year, the International Lighting Fair-intensive stage, every month exhibition debut, just ended in April in Frankfurt, Germany. The biggest difference in this year’s exhibition is that visible LEDs are becoming a mainstream light source.  LED lighting design products contests, many Taiwan’s LED Fact, chairman Li Bingjie, Everlight chairman Yeyin Fu, the Lunda chairman Su are personally view exhibitions.

Las Vegas Lighting Fair LIGHTFAIR2012 (LFI2012) coming soon in the 9th to the 11th ofthis month. However, due to the number of the recently concluded Frankfurt, Germany, International Lighting exhibition close, so there is few Taiwan’s participation manufacturers. But enterring the American Lighting brands, billion light of the market is still of its own brand ZENARDO exhibitors.

white led grow lights with the LED Lighting development

LED dominate the lighting market still need some time, however, research institutions andthe government is trying to accelerate to shorten this time, also in white led grow lights.

According to the the Databeans recently published in 2011,  in the LED’s research report data, LED lighting applications is expected to 2011 compound annual growth rate of the LED market will reach 36 percent, and in 2016, it would reach $ 4.5 billion. This data over the entire LED market, it shows that market has become the first national infrastructure in Taiwan, white led grow lights are very important part of that.

Recent technological and environmental policies for businesses in this emerging market, the more business income. Light requirements including the use of LED lights transform incandescent and fluorescent lamps. Indeed, transportation is the largest LED applications in lighting applications, the total turnover high brightness LED in 2012 will reach 5 billions and 64 millions USD.

white led grow lights with the LED Lighting development

60 watt LED lamp is the most technical superiority of the product. The product is used with remote phosphor system with patented LUXEON rebel LED. According to the U.S. Department of Energy data, it is assumed that in the United States, about half of the 60 watt bulb would be replaced by LED lights. Then, the United States each year will save $ 3.9 billion energy expenses.

Because of this huge upward trend, many LED companies optimistic about LED lighting applications. One LED company’s turnover in the first half is expected to reach 41 million, of which more than half of the lighting applications. This trend is prevalent in many highly competitive companies, such as Cree and Nichia. Although Nichia plagued by patent war, it will still be able to achieveimpressive results in the LED industry, white led grow lights included.

The LED street light market growth depends not only on the backlit display and the dashboard .Obvious advantages, civil and commercial lighting will require the transformation of incandescent and fluorescent lamps. This will enable enterprises in at least 10 years, greatly increased the production of semiconductors.

Finally, there is a question worth pondering: When the LED lights to replace incandescent, will cause large fluctuations in sales? Because the LED lamp life of up to18 years. This left time to test it.

 

Analysis for LED yard lamps

LED technique has the potential to replace traditional filament lamps, fluorescent lamps and gas discharge lamps in yard lighting. However, there are still some technologic problems of LED Street Light need to be solved:

LED technique has the potential to replace traditional filament lamps, fluorescent lamps and gas discharge lamps in yard lighting.

  1. Lighting effect. Light effect is a very important parameter for LED lamps. LED lamps can save much more energy than traditional LED products, as a result of the higher lighting effect of LEDs. LED lighting effect can be improved by choosing better LED materials and improving the internal construction of LED chips. Since this part is most likely to be realized, scientist all over the world spent most of their energy and costs on it every year. With the development of LED technique, the lighting effect of LED lamps has been improved continuously, including LED yard lighting.
  2. Power efficiency. As a type of outdoor lighting products, yard lamps are usually used during the night. This requires that LED yard lamps with single LED chip have enough luminous flux. Thus, we must have sufficient power. However, the voltage (power) provided by suppliers should not exceed a certain threshold. Otherwise, LED chips will be destroyed due to high working temperatures. Obviously, besides larger area for LED surface, high power LED components also need better cooling sections.
  3. Since lights emitted by LEDs usually concentrate within a small area (solid angle), traditional projectors are no longer useful. LED manufactures need to design new reflecting covers which correspond to the optical system structure of LED lamps.
  4. Generally, LED lighting sources are comprised of several LED chips. The discrete parameter is another technological problem. On one hand, manufactures will try hard to keep the uniformity (parameters) of LED chips within one lamp. On the other hand, they need to design more reasonable lamp structures and diver circuits in case that LED yard lamps are destroyed due to energy concentration.
  5. Normally, a set of LED yard lamps will be used in yard lighting. Thus designers need to design a connection way (in series or in parallel) for these lamps before installation. Protection circuits are necessary since the whole set of yard lights will be out of work if only one or two of them are failed.
  6. LED yard lamps have strict requirements in cooling system. Continuous working in high temperature will cause a light attenuation inevitably, which is a cannot-be-ignored problem for outdoor lighting products.

LED street lighting business: a new direction for street light manufactures

Recently, LED street lighting business has become a new direction for street light manufactures in China. LED street lights are quite different from traditional street lights: point light sources, high power consumption; Narrow beam output. These require more sophisticated designs for LED street lamps. It is a systematic process. In order to designer LED street lamps with higher performances, designers should make a study of street lighting standards and photo-mixing principles for traditional street lights, taking full advantage of LED street lamps: point light sources, controllable beam angle and long life cold light sources.

 

Recently, LED street lighting business has become a new direction for street light manufactures in China.

 

Choosing suitable LED light sources is the key to the entire designs, since they will directly impact LEDs’ performances, costs and working lives. Some LED street light manufacturers use single LED moudle with a power consumption of 10W. In fact, this design is unreasonable and has many defects: harder in photo-mixing; more glares; more difficult in heat radiation, etc. Some manufacturers tried to use the combination of several LED modules (with 3W-5W for each). This design also has defects: insufficient lighting effect and heat radiation problems. Above all, high power (10W) LED is more reasonable. With current high power LED technology, 10W LED street lamps have better lighting effect.

 

There are two main colors in street lighting: yellow light and white light. Basically, high pressure sodium lamps (HPSL) emit yellow rays. HPSL is the mainstream street lighting technique in China, due to its energy-saving property and strong fog- penetrability. However, yellow light has its own defects: low CRI. Under sodium lights, objects will be coated by yellow lights, which is a distortion. White light is closed to natural light, having much better CRI compare with yellow light. Metal halide lamps were used in the early stage of white-ray LED street lighting industry. Metal halide lamps have better CRI, but also very weak fog- penetrability and short service lives. They did not wide spread at that then. Then LED manufacturers concentrated on a newborn lighting technique: LED, and joint into LED street lighting business one after another. The normally used color temperature of LED street lamps is around 3500K (cool white). LED street lamps have higher CRI, better lighting effect, better fog- penetrability, and can work for a long time. It is impossible to prevent LED street lamps to be the mainstream products in street lighting business. Soon, traditional street lamps will be replaced by them completely.

How to improve CRI of LEDs? (3)

Theoretically, white rays can be obtained by combining three primary colors in a certain ratio (red : green : blue = 3:6:1). This technology can be used in LED display but not in LED lighting products, since it is based on the premise that we have seen the object. Objects can be seen by us due to the light reflected from them. During this process, lights will be absorbed by objects. Therefore, white rays generated by the combination of three primary colors have innate defects: objects absorb red rays, blue rays and green rays at different levels. Even they have been mixed exactly in ratio to create purely white rays, after reflecting, they cannot maintain the original ratio, leading to a distortion. That means, lit by LED lamps, objects will look different from looking them in the sun. CRI of LEDs reduces. However, it is not to say that this kind of technique is infeasible. The photo-mixing operation should be taken within LED lamps (before sending out) to improve the CRI of LEDs.

 

Three primary color LED photo-mixing technology is much mature currently. There are two different ways for photo-mixing: on the surface of LED chips; on the surface of lamp covers. Both of them have disadvantages. The former: distances between LED chips are too far for photo-mixing, causing inevitable distortions. The latter: this method will cause light attenuation. Although this type of LED lamps has a higher CRI, lights sent out by them are no longer white rays if captured by our eyes directly.

 

In recent years, many studies for three primary colors LED photo-mixing technology are focus on these two problems. Studies demonstrate that with the decrease of distances between LED lights, light mixing distances exponentially reduced. With the increase of color-scattered agent’s concentration, the light mixing effect will be increased. The balance point between LEDs’ distances (reduce) and color-scattered agent’s concentration (increase) will be the optimal value. With such solution, it is possible for photo-mixing LEDs to be white lighting sources one day.

 

This technology can be used in LED display but not in LED lighting, since it is based on the premise that we have seen the object.

 

Feature above depicts relation between light intensity and concentration of color-scattered agent. From it we can see that light attenuation is proportional to color-scattered agent’s concentration. Currently, transparent glue has a light attenuation of 5%, while glue with color-scattered agent has a light attenuation of 12%. With current technology, this problem will not be solve in short term.
