In 2010, the pilot project of the Ten Cities and Ten Thousand Miles will enter a full implementation phase and usher in a critical period.
Recently, the Ten City Wanhao Semiconductor Lighting Application Pilot City Work Conference was held in Harbin. The establishment of test indicators and the establishment of unified standards have become the main issues reflected by the representatives of 21 pilot cities. The 2010 Semiconductor Lighting Inspection Technology and Standards Forum held at the same time focused on the latest standards and testing progress in the semiconductor lighting industry, the development of semiconductor lighting test specifications and test platform construction, and the issues that need attention in standard formulation work.
The biggest problem facing the development of LED lighting industry is the lack of national standards and industry standards. Huang Jie, director of the National Semiconductor Device Quality Supervision and Inspection Center, said that the lack of national standards and industry standards will make the ten-city Wanxi pilot demonstration project undocumented. According to the quotation, it is possible to determine the winning bidding company only by quotation, which will result in waste of engineering funds or unqualified engineering quality. The timely and appropriate introduction of standards and testing has become an important guarantee for the healthy development of the industry.
Lack of standards
Wang Zhixue, deputy secretary-general of the Ministry of Science and Technology, said that semiconductor lighting is one of the few key core technologies in China, with market demand prospects, low resource energy consumption, large driving coefficient, many employment opportunities, and comprehensive benefits. Strategic emerging industries.
Such a promising industry has always been plagued by the lack of standards.
With the continuous advancement of the pilot project of the Ten Cities and Ten Thousand Miles, in order to ensure the basic performance of the bidding products for the semiconductor lighting pilot project and the quality of the application demonstration project, the development of the semiconductor lighting pilot demonstration project and the semiconductor lighting product series technical specifications are being planned. Continue to advance.
It is understood that the National Semiconductor Lighting Engineering R&D and Industry Alliance has completed the "Technical Specifications for LED Road Lighting Products for Pilot Demonstration Projects for Semiconductor Lighting", "LED Tunnel Lights" and "Implementation Rules for Supervision, Inspection, Installation and Acceptance of LED Road and Tunnel Lighting Products". Draft opinion. At the 2010 Semiconductor Lighting Inspection Technology and Standards Forum, the alliance and the Harbin Lighting Inspection Center and other institutions once again launched the "Technical Specifications for Cold LED Road Lighting Products" for comments. Yan Jun, deputy secretary-general of the National Semiconductor Lighting Engineering R&D and Industry Alliance, said that the technical specifications for LED indoor downlights and spotlights are also being compiled. In addition, the alliance has been issued by the United Nations family-level testing agencies to regularly publish product testing data for technical specifications. And the next step in the product catalog release to do the preliminary work.
Experts also made recommendations for the development 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 the overall development of semiconductor lighting, attention should be paid to supplement the defects of the existing LED lighting standard system. At present, LED lighting standards in China still lack the performance requirements of LED modules. The LED enters the luminaire after the relevant reference point limits the temperature. These two aspects are very important in the LED lighting application, and the standards are also difficult to formulate.
Huang Jie pointed out that the test standards should be based on LEDs of different power, different colors and different package forms, and the corresponding test standards and methods should be formulated. Only when the test conditions are consistent, the test results are comparable.
Standards should be tailored to local conditions
Driven by the pilot demonstration project of the Ten Cities and Ten Thousand Cities in China, the demand for the market is very strong. Many companies hope that the standards will be introduced as soon as possible. However, LED lighting technology is developing very fast, and the product may be updated in a few months. Therefore, the standard must not only meet the current product requirements, but also be forward-looking. Hua Shuming, director of the National Electric Light Source Quality Supervision and Inspection Center (Beijing), believes that the industry standards for specific performance requirements, to give the product a certain upside, it is not easy to stipulate too much to meet the development needs of LED lighting technology.
Liu Muqing, director of the Institute of Electric Light Sources at Fudan University and director of the Department of Electric Light Sources, stressed that the LED lighting industry is an emerging industry, and the standards of various countries are being formulated. Therefore, the premise of standard setting is the research standard. Fan Yuxi, chairman of the National Semiconductor Lighting Engineering R&D and Industry Alliance Industry Executive and Chairman of Xiamen Hualian Electronics Co., Ltd., believes that the standards themselves can have multiple levels. National standards should be in line with international standards, and local standards should conform to the basic norms of national standards. According to the local roads and climate characteristics, each locality regulates the corresponding requirements, and it is a useful supplement to the national standards. Through local practice, it is continuously found that the problems are continuously improved, and the local standards or standards are continuously improved, which is meaningful for promoting and improving national standards. .
The internationalization of semiconductors is an inevitable trend. This requires not only that China should 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 the field of LED lighting product testing methods, standards have not yet formed or not yet mature, form new ways of thinking to influence international standards, and strive to have more say in the formulation of international standards. At the same time, the experts also pointed out that for the relevant international standards, translation and appropriate adjustments should be made to make them suitable for use in China.
Government promotes industrial development
The current lighting industry is facing the transformation of industry, technology and knowledge. Through scientific and rational planning and investment, China is likely to seize the commanding heights of international semiconductor lighting technology and industry, and become a strategic pilot industry in the field of optoelectronics in the future. The Ten City Wanhao pilot demonstration project will play an important role in leading the rapid development of the semiconductor lighting industry.
China has a strong lighting industry base 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 Plan and other scientific and technological programs, China has initially formed a relatively complete industrial chain from epitaxial wafer production, chip fabrication, and device packaging integration. At present, there are more than 400 enterprises engaged in the scale production of semiconductor LED devices and lighting systems nationwide, 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 engineering industrialization bases in Shanghai, Dalian, Nanchang, Xiamen, Shenzhen, Yangzhou and Shijiazhuang. The Yangtze River Delta, the Pearl River Delta, the Delta Triangle and the northern region have become the gathering places of China's LED lighting industry.
Throughout the global market, examples of government funding to promote industrial development abound, and the spread of solar power in Germany to every household is a good example of success.
The city Wanhao pilot demonstration project has already clarified that the national LED lighting should exceed 10,000 baht. National street lamps and 24-hour continuous use of tunnel lights have become the first major replacement projects. The subways in Beijing, Shanghai, Guangzhou and Shenzhen have started and popularized LED fluorescent lamp energy-saving projects. This will drive the comprehensive development of the technology and production capacity of the LED lighting industry, creating new opportunities in the industry chain.
Benefiting from the stimulation of the country's policy of expanding domestic demand, the LED lighting industry has developed rapidly, and its upstream, middle and downstream industrial chains have also 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 application. At present, South China, East China and North China have shown the vigorous development of the LED lighting industry.
