Known as the "third lighting revolution," LED industry has get great attention from the government and sought by this industry with its advantages of energy saving and environmental protection. However, in a burst of applause, LED still faces lack of core technology, lack of industry standards, high prices, difficulty in large scale problems.

Technology is not perfect

"Is not very mature." Yesterday (June 9), held in Guangzhou, the "Energy Conservation Awareness Week 2010 and Guangdong LED Industry Summit Forum", South China University of Information Technology professionals the main display and photovoltaic Ren Shangsheng the case said. In his view, due to technical and other constraints, China's LED industry does not think so well.

In recent years, rapid development of China's LED industry. Has formed a Pearl River Delta, Yangtze River Delta, Jiangxi and Fujian, Beijing and Dalian, the four regions. Some experts expect China's LED production value in 2010 will reach 1,500 billion yuan, twice in 2008. However, the rapid expansion in the industrial scale, when R & D but was left far behind.

In ...
... this regard, the Guangdong Provincial Academy of Social Sciences Institute of Industrial Economics, said the Xiaomei, industry technical progress is slow, low levels of product innovation, technological content as a result of insufficient core competitiveness of the lack of LED industry.

Extension of the entire LED industry chain, including chip, package, and application in several areas, the lack of key technologies, most of the enterprises in China are concentrated in the areas of packaging and downstream applications, high-end chain weak link in the upstream technology controlled by others. Determined to enter the extension of the upstream industry chain enterprises, generally bleak circumstances, there is no lack of them forced out of business.

Lumen LED lighting issues are also worn on the head of the straitjacket business. LED light source is now common problem of light decline. Some LED lights installed less than a year to appear serious decay in brightness. According to still win the text Introduction, LED lights will work into the light and heat energy, the component temperature rise for each 2 ℃, lamps reliability will be decreased by 10%, when the temperature rose to 74 ℃ 63 ℃ by the time, LED Average life will reduce the 3 / 4.

Widely used products difficult

LED technology is imperfect, but also hinder the product in the market widely used. LED lights products (christmas lights for sale) only when it can enter the homes of ordinary people is unknown, is the national implementation of the "city of ten thousand ten" project is also the market freeze line. LED products, large scale difficult.

Hundreds of high prices frequently to the needs of ordinary people turned away, but not yet ripe for large-scale commercial applications, so many people have to explore how to get rid of LED "saving money is not festival" the curse .

Government procurement and other aspects of support, to a certain extent, promoted the LED in the market, but in this government-created demand, some companies tend to over-optimistic, flock to. However, some quality products related to flood the market, resulting in objective consumer distrust of LED products, promote further increase the difficulty.

LED booster by the industry as a contract energy management also had to put its own onto the road. Since the introduction of energy management contracts in China, has been in a tepid state. Contract energy services company also small, higher risk of problems. Guangdong Investment Fund Operation Green Industry Office of the Deputy Director of He Wenkai think it is still faced with the contract energy management technology, credit and capital these three barriers. Testing water project is only a role model, it still needs to be improved in terms of scale and market-orientation.from: wholesale LED Christmas lights
