Semiconductor lighting pilot encountered the bottleneck of lack of industry standards

in 2010, the pilot demonstration project of "ten cities and ten thousand lamps" will enter the full implementation stage and usher in a critical period

recently, the working conference of "ten cities and ten thousand lamps" semiconductor lighting application pilot cities was held in Harbin. The establishment of detection indicators and unified standards have become the main issues reflected by the representatives of 21 pilot cities. The 2010 semiconductor lighting testing technology and Standards Forum held at the same time focused on the latest standards and testing progress of the semiconductor lighting industry at home and abroad, the formulation of semiconductor lighting testing specifications and the construction of testing platforms, as well as issues needing attention in the formulation of standards

"the biggest problem facing the development of LED lighting industry at present is the lack of national standards and industry standards", said Huang Jie, director of the national semiconductor device quality supervision and inspection center. The lack of national standards and industry standards will make the bidding of "ten cities and ten thousand lamps" pilot demonstration project groundless, and it is possible to determine the winning enterprise only by quotation, which will cause a waste of project funds or unqualified project quality. The timely and appropriate introduction of standards and testing has become an important guarantee for the healthy development of the industry

Wang Zhixue, Deputy Secretary General of the Ministry of science and technology, said that semiconductor lighting is one of the few strategic emerging industries in China that has gradually mastered the key core technology, has the prospect of market demand, and has the advantages of low resource energy consumption, large driving coefficient, many employment opportunities and good comprehensive benefits

such a promising industry has been plagued by the lack of standards

with the continuous promotion of the pilot demonstration project of "ten cities and ten thousand lamps", in order to ensure the basic performance of the bidding products of the pilot project of semiconductor lighting and the quality of the application demonstration project, the pilot demonstration project of semiconductor lighting and the formulation of the technical specifications of the series of semiconductor lighting products are being systematically and continuously promoted

it is understood that the national semiconductor lighting engineering R & D and industry alliance has completed the draft for comments of the technical specification for LED road lighting products of semiconductor lighting pilot demonstration project, LED tunnel lamp and the implementation rules for supervision, inspection, installation and acceptance of LED road and tunnel lighting products. At the 2010 semiconductor lighting testing technology and Standards Forum, the alliance can meet the needs of specific products, and jointly with Harbin lighting testing center and other institutions once again launched the "technical specifications for LED road lighting products in cold areas" for comments. Ruan Jun, Deputy Secretary General of the national semiconductor lighting engineering research and development and Industry Alliance, said that l was also preparing the technical specifications for indoor downlight and spotlight products by adding pre dispersed foaming agent ed. when establishing integrated and one-stop customs clearance services for transportation (maritime), customs, inspection and quarantine, and border inspection, in addition, the alliance has cooperated with national inspection agencies to regularly publish product inspection data, Do a good job in the preliminary work for the formulation of technical specifications and the next release of product catalogs

experts also made suggestions on the formulation of LED lighting standards and specifications. Yu Anqi, executive deputy director of the national electric light source quality supervision and Inspection Center (Shanghai), said: "In terms of the overall development of semiconductor lighting, attention should be paid to supplementing the defects of the existing LED lighting standard system. At present, China's LED lighting standards still lack two aspects: the performance requirements of LED modules for lamps and the temperature limit of relevant reference points after LEDs enter lamps. These two aspects are very important in the application end of LED lighting, and it is difficult to formulate standards."

Huang Jie pointed out that the test standards should be formulated for LEDs with different power, different colors and different packaging forms. Only when the test conditions are consistent, the test results can be comparable

standards should be formulated according to time and local conditions

driven by the pilot demonstration project of "ten cities and ten thousand lamps", the market demand is very strong, and many enterprises hope that the standards will be issued as soon as possible. However, LED lighting technology is developing rapidly, and products may be upgraded in a few months. Therefore, the standard should not only meet the product requirements at this stage, but also be forward-looking. Hua Shuming, director of the national electric light source quality supervision and Inspection Center (Beijing), believes that the requirements of industry standards for specific performance should leave a certain room for products to rise, and it is not easy to be too rigid, so as to meet the development needs of LED lighting technology

liumuqing, director of the electric light source research institute and director of the electric light source Department of Fudan University, stressed that the LED lighting industry is an emerging industry, and national standards are being formulated. Therefore, the premise of formulating standards is to study standards. Fanyubo, the executive chairman of the national semiconductor lighting engineering research and development and Industry Alliance and the chairman of Xiamen Hualian Electronics Co., Ltd., believes that the standard itself can have multiple levels. National standards should be in line with international standards, and local standards should comply with the basic norms of national standards. Local standards regulate the corresponding requirements according to the local road and climate characteristics, which is a useful supplement to the national standards. Through local practice, problems are constantly found and improved, Continuous improvement of local norms or standards is of great significance to promote and improve national standards

the internationalization of semiconductors is an inevitable trend, which requires China not only to actively participate in the formulation of international standards, but also to integrate with the world while formulating domestic standards. Yu Anqi said, "we can strengthen research in areas where LED lighting product testing methods and standards have not yet been formed or mature, form new perspectives and methods to influence international standards, and strive to have more say in the formulation of international standards." At the same time, experts also pointed out that the relevant international standards should be translated and appropriately adjusted to make them suitable for use in China

the government promotes industrial development

at present, the lighting industry is facing the transformation of industry, technology and knowledge. Through scientific and reasonable planning and investment, China may seize the commanding heights of international semiconductor lighting technology and industry, and become a strategic pilot industry in the optoelectronic field in the future. The pilot demonstration project of "ten cities and ten thousand lamps" will play an important role in leading the rapid development of semiconductor lighting industry

China has a strong lighting industry foundation and a huge lighting market. China is now one of the world's largest producers and exporters of lighting appliances. With the support of the 863 program and other scientific and technological programs, China has initially formed a relatively complete industrial chain from epitaxial wafer production, chip preparation, device packaging and integrated application. At present, there are more than 400 enterprises engaged in the large-scale production of semiconductor LED devices and lighting systems in China, and the packaging business has occupied a considerable share in the international market

driven by the national semiconductor lighting project, China has formed seven National Semiconductor Lighting Project Industrialization Bases in Shanghai, Dalian, Nanchang, Xiamen, Shenzhen, Yangzhou and Shijiazhuang. Yangtze River Delta, Pearl River Delta, Fujian Delta and Northern China have become the gathering places of LED lighting industry in China

throughout the global market, there are many examples of government funding to promote industrial development. The popularization of solar power generation in Germany to every family is a good example of success

the pilot demonstration project of "ten cities, ten thousand lights" has made it clear that there are more than 10000 LED lights in the country, and the national street lights and tunnel lights that are used continuously for 24 hours have become the key projects to be replaced first. Subway projects in Beijing, Shanghai, Guangzhou and Shenzhen have launched and popularized energy-saving LED fluorescent lamps. This will drive the technology and production capacity of the LED lighting industry to develop in an all-round way and create new opportunities for the industrial chain

benefiting from the stimulation of the national policy of expanding domestic demand, the LED lighting industry has developed rapidly, and its upstream, middle and downstream industrial chains have been improved accordingly. At the same time, all relevant technologies in the LED lighting industry chain can be improved and developed on the basis of practical applications. At present, South China, East China and North China have shown the vigorous development momentum of LED lighting industry
