In 2010, the “Ten Cities and Ten Thousand Miles†pilot demonstration project will enter a full implementation phase and usher in a critical period. On January 7, 2010, the “Ten Cities and Ten Thousand†Semiconductor Lighting Application Pilot City Work Conference was held in Harbin. Representatives from 19 pilot cities in 21 pilot cities attended the meeting and summarized the development of the localities. The establishment and unification of test indicators The establishment of standards has become one of the main issues reflected by representatives from all over the world. In the same period, sponsored by National Semiconductor Lighting Engineering R&D and Industry Alliance, Harbin Science and Technology Bureau hosted the "2010 Semiconductor Lighting Inspection Technology and Standards Forum", the latest standards and testing progress in the semiconductor lighting industry, semiconductor lighting test specification development and testing platform construction and The issues that need attention during standard setting work are discussed intensively. Chen Weimin, director of the Optoelectronics and Measurement and Control Technology Research Center of Chongqing University, Li Bingjie, chairman of Taiwan Jingyuan Optoelectronics, and Ye Haofu, chairman of Taiwan Everlight Electronics Co., Ltd., attended the conference.
"The biggest problem facing the development of the LED industry 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 “Ten Cities and Ten Thousands†pilot demonstration project undocumented at the time of bidding. It may be possible to determine the winning bidders only by quotation, which may result in waste of engineering funds or unqualified engineering quality. phenomenon. The timely and appropriate introduction of standards and testing has become an important guarantee for the healthy development of the industry.
With the continuous advancement of the “Ten Cities and Ten Thousand Miles†pilot demonstration project, in order to ensure the basic performance of the semiconductor lighting pilot project bidding products and the quality of the application demonstration project, the semiconductor lighting pilot demonstration project semiconductor lighting product series technical specification development work is planned Continued advancement. 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" ( Consultation draft). In 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 already issued a national inspection agency to regularly publish product inspection data for technical specifications. The next step is to publish the catalogue and do the preliminary work.
Experts also provided valuable comments on the development of LED 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, the LED module in China still lacks the performance requirements of LED modules. After the LED enters the luminaire, its related reference point limits the temperature. Both of these aspects are very important in the LED application, but it is also difficult to formulate."
Director Huang Jie pointed out that the testing standards should be based on LEDs of different powers, colors and packages, and the corresponding test standards and methods should be developed. Only when the test conditions are consistent, the test results are comparable.
Under the impetus of “Ten Cities and Ten Thousand Citiesâ€, China's LED industry has a strong demand in the market. Many companies hope that the standards will be introduced as soon as possible for reference. But LED technology is growing fast, and the product may be a new generation in a few months. In this regard, the standards for the current rapid development of data indicators must not only meet the current product requirements, but also be forward-looking. National Electric Light Source Quality Supervision and Inspection Center (Beijing) Hua Shuming believes that for some performance requirements, it is necessary to give the product a certain upside, not easy to premature regulations, in order to adapt to the development needs of LED technology.
The internationalization of semiconductors is an inevitable trend, which not only requires us to actively participate in the formulation of international standards, but also to integrate with the world while formulating domestic standards. Professor Liu Muqing from Fudan University pointed out that the LED industry is developing rapidly and the international standards are not perfect. The standard setting work is an important strategic deployment in the development of the LED industry. Director Yu Anqi said at the meeting: "We can strengthen research and form new methods of view in areas where LED product testing methods, standards have not yet been formed or are not yet mature, to influence international standards, and strive to have more in the development of international standards. The right to speak.†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.
