LED lighting forward difficulties

LED lighting, known as the "third lighting revolution", the advantages of energy saving and environmental protection by the government attaches great importance to the industry and sought after. But in a piece of applause, LED still faces the lack of core technology, the lack of industry standards, high prices, a large area of promotion difficulties and other issues.

Technically still not perfect

"Not very mature yet. "In June 9th, held in Guangzhou," 2010 energy conservation week and the Guangdong LED Industry Summit Forum, "South China University of Technology information display and optoelectronic technology, director of the professional Shang Shengru said. In his view, due to technical constraints and other aspects, the development of China's LED industry is not as good as imagined.

In recent years, the rapid development of China's LED industry. Has formed the Pearl River Delta, Yangtze River Delta, Jiangxi and Fujian, Beijing and Dalian, these four regions. Some experts predict that in 2010 China's LED output value will reach 150 billion yuan, an increase of two times in 2008. However, the rapid expansion of the scale of the industry, technology research and development has been far behind.

In this regard, Xiang Xiaomei, director of the Institute of industrial economics, Guangdong Academy of Social Sciences, said the industry's technological progress is slow, low degree of product innovation, technical content is not enough, leading to lack of core competitiveness of LED industry.

LED the whole industry chain, including several extension, chip, package and application fields, due to the lack of key technologies, the vast majority of enterprises in our country are concentrated in the downstream packaging and application fields of high-end industry chain is relatively weak, the technology of heteronomy. Intends to enter the upstream industry chain, such as the extension of the general situation bleak, which are forced to withdraw from the enterprise.

Light problem is worn on the head of the LED lighting business inhibition. Now the general existence problem of LED light source light. Some LED street lamps installed in less than a year, the phenomenon of severe attenuation of brightness. According to Wen Shangsheng introduction, LED lamp can be converted into light and heat energy to work in electricity, component temperature increase of 2 degrees, the lamp reliability will drop by 10%, when the working temperature from 63 degrees up to 74 degrees, the average life expectancy of LED will be reduced by 3/4.

Products are widely used

LED technology is not perfect, but also hinder the wide application of products in the market. Not only when LED products can enter the homes of ordinary people is unknown, that is, the implementation of the national "Ten City million" project is also in the market cold line. LED large area of product promotion difficulties.

Hundreds of thousands of hundreds of high price to the needs of ordinary people in the door, and the large-scale commercial application is not mature, so many people have to discuss how to get rid of LED "section is not saving money" spell.

Government procurement and other aspects of support, to a certain extent, promoted the LED of the market, but in this government to create demand, some enterprises tend to be too optimistic, the bees come to. Some of the quality of the product also went to the market, objectively caused consumer distrust of LED products, further increase the difficulty of promotion.

By the industry as a LED booster contract energy management also had to put themselves on the road. Since the introduction of China's contract energy management model, has been in a state of lukewarm. Contract Energy Service Companies also has small scale, high risk issues. Deputy director of the office of Guangdong green industry investment fund executive vice president, he believes that the contract energy management is still faced with technology, credit and money these three barriers. Test the water project is only a demonstration role, in terms of scale and market has yet to be improved.
