GE Lighting's LED intelligent street lighting system

 

Wang Jia Nuyi bridge recently, GE Lighting in New Zealand with several sets of new LED street lighting has a long history of local updates of traditional lighting systems. Wang Jia Nuyi River is the third largest river in New Zealand has a special significance in Maori culture, and Wang Jia Nuyi Bridge is the only one of several road and bridge rivers.

 

In order to improve the lighting conditions in Wang Jia Nuyi bridge main road, the City Council began to try to replace the traditional lighting technology, with different LED light source aimed at the application of energy-saving program. The new road lighting solution must maintain the same brightness as with conventional light sources have to meet the requirements of energy efficiency savings. Local lighting design company in New Zealand EvolveNZ GE Lighting of the 80WR150LED products.

 

EvolveNZ company general manager John Birks said: “The lighting configuration to restore the natural light to bring a more secure feeling and a white  light makes the space more modern and a sense of vitality in the night, can more clearly see the real life environment. we hope that this lighting technology to attract more people to travel, to experience the night scenery of their host cities. ”

 

Wang Jia Nuyi City Council infrastructure and assets Chairman of the Committee Ray Stevens said: “The new alternative can bring many potential advantages and benefits to the public, no doubt, members of the public will notice the new LED intelligent street lighting to generate white light, rather than issued by the installation of sodium orange light. Wang Jia Nuyi City Council will be phased in LED light source instead of the traditional lighting products, until it is completely replaced. ”

 

Seek long-term development of LED household lighting under the disorderly competition

 

Seek long-term development of LED household lighting under the disorderly competition

 

 

Response to the “patent war”. 2010 there will be some of the important field of white LED patent expires, other words, LED industry in recent years into a frequent patent litigation battle. According to incomplete statistics, the global LED household lighting application 124,000, which the United States, 20000 China, 25000, 49000 Japan accounted for. The key is the 25000 LED patent in China, mostly concentrated in the middle and lower reaches of the whole industrial chain, mostly design, utility model patents, invention patent very little. All have some peripheral patent in the upstream industry chain, but the core patents master degree.

 

 

 

Balance productivity growth and market demand. According to incomplete statistics, in 2010 only listed company in the investment in the field of LED over 30 billion yuan, 20 billion yuan of three safety photoelectric BDO Runda 4 billion yuan. LED industry investment in 2010, about 37% to invest in the upstream chip areas, 52% to invest in downstream applications, signs of overcapacity initially appeared. 1 July 2011, China MOCVD equipment increased by more than 200 units, is expected in 2012, China LED household lighting chip production capacity is 10 times that of 2010. MOCVD equipment in China more than 500 units, count 96 projects under construction, the total number of over 1600. According to statistics, the sapphire substrate manufacturing enterprises 41, planning a total investment of 44.7 billion yuan, including the planning of projects under construction amounted to 12.08 billion yuan in the projects under construction production capacity of 101 million / year. However, due to the global economic situation is not optimistic, the LED high bay chip demand declining. How to expand the LED general lighting market, and how the government should support the market, how to cultivate, all we need to solve.


The development of solar powered LED street lights should have a long-term vision

 

The development of solar powered LED street lights should have a long-term vision

 

Focus on new technology development. Such as the solar powered LED street lights internal quantum efficiency enhancement, as well as changes in package structure and new phosphor / quantum dots, the transparent substrate, contact materials, reflective materials, the second optical / lighting reflector’s design, and development of high-performance drive power .

 

OLED challenges can not be ignored. Solar powered LED street lights and OLED have their own strengths, when the LED high bay lighting market, but also face the competition of “compatriots” OLED. OLED display technology has been relatively mature, and has entered the market, lighting technology is taken seriously, in the rapid development of. The commercial grade white OLED light efficiency reached 50lm / W general lighting lights more than two times the life expectancy has reached 100,000 hours. And laboratory research and development of white light emitting efficiency of 120lm / W, is close to the U.S. Department of Energy requirements for lighting materials 150lm / W. Of course, OLED flat light source is also facing some problems: poor antioxidant capacity of the OLED light-emitting materials, power, afraid of the water, you need to vacuum glass seal, so need LTPSTFT substrate, OLED applications in the field of large-size the cost will be high; the yield of large-size OLED panels are still not high, a substantial increase in the cost of OLED product line, but also makes the production can not improve quickly; light-emitting material properties, component life by the effects of restrictions of the short board; surface light source specifications and drive power standard is yet to be established.

 

Should mains LED lighting industry put all of their attention on a longer life

 

Should mains LED lighting industry put all of their attention on a longer life

 

LED lamps for its long life, and environmental protection advantages, become a popular trend of the moment lamps. Just how long the life of the LED lamps? Generally believed not fake LED life of 100,000 hours, LED made ​​of light would be to have a certain power, the greater the power and cooling requirements of the higher, if the heat is not good, LED life is affected. Then there is the drive power supply part, and so on with the life of the LED lights. In addition also affects the quality of life, so normal in the mains LED lighting industry, LED life value parameter should be 30000-50000 hours. In fact, such a life already meet most lighting needs, far beyond the energy saving lamps, LED lamps of the incandescent lamp life, whether you want the blind pursuit of longer life?

 

Incandescent lamp life of standard definitions for 1000 hours, but for a long time occupied a civilian home lighting market, the most important reason is that the price advantage. Mains LED lighting life have an advantage, but the price allows consumers prohibitive. I believe that LED lamps have a certain life span advantage, no need to go too much in pursuit of longer life, as necessary to the pursuit of too high light efficiency. Compared to the price of energy-saving lamps, LED high bay lamps prices at a disadvantage, the people at home lighting in order to gain market share, reduce costs, speed up the popularization and application is king.

 

How to improve the working life of LED street light bulbs

 

How to improve the working life of LED street light bulbs

 

Recent U.S. Energy Star is being drafted to discuss the standards of the LED street light bulbs, among the more controversial point is that life on the minimum requirements, the EPA may be consumer lamp life requirements down to a minimum of 10,000 hours from 25,000 hours, because 10,000 hours compared to three hours daily point count has more than nine years of life. The latest EPA’s standard is that you can nominal life, the minimum of 10,000 hours, of course, if the test results, you can also nominal 25,000 hours or more.

 

The use of 9 years is enough for general home applications, hotels, subway stations, such as places of lighting required for a long time, you can use long-life LED street light bulbs, which indicates that the EPA later no longer LED lamp life across the board, only the minimum life requirements, the lighting of different places you can demand for life lamps, reflecting differences in demand for domestic enterprises is really good, so that small businesses and large enterprises according to their own conditions, to reduce the cost of LED bulbs while different levels, but also to improve the quality of their products, accelerate product updates and promotion.

 

Deal with material shortages. High brightness LED high bay chips metal indium is based on. The earth’s crust in the content in rows in the 61th, strategic metals in the number two, the development and application of growing, not rich reserves of global growth, the price, the expected future will appear periodic shortages. If LED into the general illumination market, bring problem is abundant raw materials? At present, many foreign countries and institutions and enterprises have begun to explore new chip in material, our country should also pay attention to this problem, to deal with the possibility of future rising prices of raw materials, research and development of new LED material.

 

Most LED lamp manufacturers face serious pressure on the stock

 

Most LED lamp manufacturers face serious pressure on the stock

 

LED chip supply in 2011 is still as high as 174 billion, only 129 billion of chip demand, oversupply ratio is as high as 35%, most LED manufacturers faced with a huge inventory adjustment pressure in the second half of 2011. Outlook 2012, huge MOCVD machine capacity not yet fully released, the industry as a whole glut is still difficult to solve, however, has a patent threshold and high-tech manufacturers still have a chance to ride out the storm in such a plight.

 

The recent end-market demand by the global downturn, many LED lamp manufacturers sharp drop in export orders. The only commercial lighting project with the public sector there are still some orders. China LED observe that many small and medium-sized LED lamp manufacturers reduced because of export orders, coupled with increasingly fierce competitive environment, there are still many manufacturers face a crisis of failure before the Chinese New Year, also makes the upstream manufacturers more careful selection of customers and the amount of open accounts .

 

In the situation of caution shipping and inventory water level steadily increased, most manufacturers choose to reduce capacity utilization, and force employees to leave to control costs and reduce output, but how to reduce the huge inventory levels or various LED high bay lighting manufacturers imperative.

 

As regards the consumption of large number of LED backlight LCD TV market, in 2011 by the global economic downturn, the global LED-backlit LCD TV (LEDTV) shipments obviously not as good as expected. LCD TV shipments in 2011 the total raised to 203 million units from 220 million audience. But with the major events including the World Cup in Brazil, as well as TV brands have introduced low-cost LED backlit TV to stimulate demand, LCD TV sales volume expected for the emerging markets is expected to increase, then in 2012 for LED backlighting market will be helpful.

Guangdong becomes LED high intensity lighting developed area

 

Guangdong becomes LED high intensity lighting developed area

 

The past two years, the average growth rate of Guangdong LED industry output more than 40 percent in 2010, the province’s LED industry output value of 85.3 billion yuan, nearly 3000 enterprises, the scale of the industry accounts for about 50 percent of the country’s output value and size are among the first in the country. The 2011 Guangdong Province LED industry reached 150 billion yuan output value and the scale continues to rank first in the country. Expected by the end of 2012, the LED high intensity lighting industry in Guangdong Province is expected to be over 300 billion yuan of output value in emerging industry clusters.

 

Faced with the blowout of the international and domestic, domestic and foreign investment merger integration of upstream and downstream enterprises to accelerate the process, the traditional lighting companies, state-owned capital, private capital swarmed off the LED high bay investment boom.

 

The past two years, Guangdong has a number of LED Concepts successfully knocked on the door to capital markets listed in the Shenzhen Stock Exchange, the country star power, Hongli Opto-electronic ground on the optical, optoelectronic Lehman, Ruifeng power, Chau Ming technology, but also coming soon to a small board of Zhongshan mulinsen. Traditional lighting companies listed companies involved in the LED high intensity lighting industry, the company Foshan Lighting, Fanta, snow Wright; halfway reached the LED Guangdong ganhua BDO Runda, Konka A, Han’s Laser, or backdoor. or mergers and acquisitions, or to increase their investment in various ways to enter the LED industry. There are dozens of LED companies have completed shareholding transformation, but also ambitious to wait for an opportunity to enter the capital market.

Win the pearl river delta is the final goal for LED floodlight manufacturers

 

Win the pearl river delta is the final goal for LED floodlight manufacturers

 

With the acceleration of the urbanization process in China, low-carbon economy, green concept deeply rooted among the semiconductor lighting industry has grown the past two years has become a popular industry in the listed company in Guangdong, Guangdong has also emerged as the domestic LED floodlight manufacturers one of the most developed areas. In the dual context of policy support and market demand, Guangdong LED industry has shown explosive growth.

 

View from industry, regional development, Guangdong LED industry is most concentrated in Shenzhen City, Guangzhou, followed by other more concentrated area, including Zhuhai, Foshan, Dongguan, Zhongshan, Huizhou. Among them, the LED floodlight manufacturers in Shenzhen City, strong R & D capabilities to become solar LED lighting the world’s largest production and supply base, LED backlight major global production and supply base, the largest LED display manufacturing and supply base, LED packaging and LED lighting the lighting of the major production regions. LED enterprises in Guangzhou City, a small number, but a high concentration, driving ability, in the high-end level in the domestic LED high bay lighting industry, the innovative capacity and potential for sustainable development.

 

Wang Dian-fu, president of Shenzhen LED Industry Association, pointed out that the LED industry in Guangdong Province showing the full flowering of the potential, has formed a complete industrial chain and supporting the early cluster effect. More and more enterprises, especially to master the core technology of the upstream chip giant, have settled in Guangdong. Upstream chip giant settled, and further stimulate the development of supporting industries in the middle and lower reaches.

LED gu10 downlight: trend in the survival of the fittest


LED gu10 downlight: trend in the survival of the fittest

 

Several cities in Guangdong will be the development of LED gu10 downlight industry as a pillar industry, everyone wants a share in the LED field, only Dongguan, there are more than 200 LED business. Launched the project, most of them are concentrated in the downstream packaging, redundant construction signs are now beginning. This shows that Guangdong LED industry has been formed epitaxy, chip, package, and application of industrial chain, but not balanced in all aspects of development, showing a weak link in the epitaxy, chip, package, application links the pattern.

 

In the upper reaches of the epitaxial wafer and chip area, the lack of core technology in the short term is difficult to obtain a major breakthrough. LED gu10 downlight industry, the upstream sapphire substrate production overcapacity most serious; the middle reaches of the packaging industry capacity relative surplus of the worst anti-risk ability, the industry is expected by the end of nearly 10 percent of enterprises to be eliminated; and downstream LED applications overall performance better. This can be gleaned clues from the stock performance of listed companies of Guangdong LED concept.

 

On May 1 last year, five LED high bay lighting electrical standardization technical committee to develop standards implemented. To industry sources, after the implementation of the GB, the cost of each product will be an increase of eight yuan to 10 yuan, the profits of some of the products on the market only 3 yuan or less. This also means that if the standards are strictly implemented, there will be a lot of LED companies have been eliminated.

The tide of LED floor lighting will continue

 

The tide of LED floor lighting will continue

 

At present, the world’s scarce resources, the energy crisis has become a bottleneck restricting economic development. LED high bay lighting industry to thrive in such an environment under the major LED floor lighting companies are trying to enter the capital market, resulting in nearly two years, LED lighting companies listed on the height of the At present, China’s LED lighting industry is in a stage of rapid development, the performance of the LED listed companies in various areas of applications, the public admiration on this emerging industry, the LED lighting industry in China under the leadership of the listed enterprises in the next few years by leaps and bounds subvert the existing pattern of China’s lighting industry.

 

Number increases, the quality will change along with the listed companies to raise funds to expand their production lines to enhance capacity, improve the enterprise’s total production. Topband shares to be 3.8 million yuan to build photoelectric industrial park, BDO Runda smashing the 3 billion yuan Yu Jian continent’s biggest LED floor lighting package base, Tiantonggufen 360 million yuan investment LED project the Zijin photoelectric proposed 29-billion in the Xinjiang Production and Sapphire the crystal LUCIDITY photoelectric Order four production LED epitaxial wafers MOCV production equipment, Jufei photoelectric proposed to enhance the capacity as the first point of the development of the company. It can be seen, in large part because of current LED floor lighting companies listed in order to enhance their capacity to increase total output, lower and lower low-cost through economies of scale.
