Construction of a public inspection and evaluation platform for semiconductor lighting

I. The significance of building a public inspection and evaluation platform for semiconductor lighting Semiconductor lighting sources have significant advantages such as energy saving, environmental protection, safety, easy driving, long life, rich color, reliable performance, etc. The semiconductor lighting technology has developed over forty years [ 1-4], semiconductor light source has become the hottest and most eye-catching light source in the world, especially the luminous efficiency of LED is greatly improved. Semiconductor lighting is considered to be the new solid-state cold light source most likely to enter the general lighting field in the 21st century. And one of the most promising high-tech fields. As an emerging force in the history of human lighting, semiconductor lighting has a huge application market and development space. In 2003, the Ministry of Science and Technology, the Ministry of Information Industry and the Chinese Academy of Sciences and other eight departments and industries, and Beijing, Shanghai and other 15 local governments launched the semiconductor lighting project in China. After several years of hard work, the national “10th Five-Year” semiconductor lighting project was successful. carry out. During the "11th Five-Year Plan" period, the state will promote the semiconductor lighting project as a major project. At present, the National High-Tech Research and Development Program, a major project in the field of new materials technology, "Semiconductor Lighting Project" has been officially launched. However, at present, there is no well-equipped and impartial testing mechanism for the detection of LED performance parameters of semiconductor lighting sources. There is no authoritative certification body and uniform and standardized testing instruments and methods, which make the LEDs upper, middle and lower. Manufacturers are at a loss and do everything, causing many unnecessary repetitive investments and technical disputes, increasing the cost of enterprises, damaging the image of enterprises, seriously affecting the rapid development of the semiconductor lighting industry, and the long-term development of China's semiconductor lighting industry. It is quite unfavorable to connect with the world. Facing the historical opportunity of semiconductor lighting, China should solve the common key of quality inspection in the development of LED industry by building a high-level public inspection and evaluation platform for semiconductor lighting according to the development of the industry, the needs of enterprises and the existing basic conditions. technology. LED as a semiconductor illumination source is both a semiconductor device and a new type of light source. In the detection, it is necessary to measure its electrical parameters, optical parameters, thermal parameters, and to study the visual effects and psychological responses of its optical radiation characteristics to the human eye. At the same time, as an illumination product, an authoritative safety certification is required. As the application of semiconductor lighting products is still in its infancy, and its application is wide and diverse, its testing methods and standards have become one of the focuses of the industry at home and abroad. At present, there are few LED standards that can be used internationally. The domestic standards have just begun to be formulated. The Ministry of Information Industry established the "Semiconductor Lighting Technical Standards Working Group" in January 2005 to organize, formulate, submit, and approve the LED-related standards. 11 items, far from meeting the requirements for the development of LED application products. Therefore, under the current situation, how to detect and check the quality of LED products has become an urgent problem for the government and enterprises. Because the scale of Chinese enterprises is not large, it is difficult to conduct research on semiconductor lighting test methods within the enterprise, and these work cannot be avoided in the process of standard setting. Therefore, the public inspection and evaluation platform for semiconductor lighting is established as an authority. The impartial testing organization conducts test comparisons for the company's products and provides convincing product quality testing data. On the other hand, the semiconductor lighting testing methods and instruments are studied on the public testing and evaluation platform. The research results can be directly The state sets standard services. To build such a public testing and evaluation platform, there are currently no successful cases in China for reference. However, the target positioning must be clear when constructing, and must be different from corporate behavior. It should be positioned in public testing and evaluation, which is reflected in the enterprise. Service, service to the industry. In the National High Technology Research and Development Program (863 Program) in 2006, it was clearly stated that “two-standard semiconductor lighting evaluation and testing centers will be established throughout the country to explore operational mechanisms for product testing, evaluation, and compliance and industry development. Provide services and support." Platform construction must carry out system and mechanism innovation to attract first-class talents to join. On the one hand, there must be government policies and financial support and manpower coordination, on the other hand, there must be a high-level research and development team. In addition, there is a need for the active participation of companies (especially large companies). In the construction of the platform, in order to avoid low-level redundant construction, the decision-makers who need platform construction are far-sighted. According to the regional development of China's semiconductor lighting industry, it is first established in areas that are urgently needed and have development prospects. After the platform is completed, it must be able to adapt to the advancement of semiconductor lighting industry technology and truly serve the industry: it can provide public R&D, product testing, test analysis, talent training, etc.; and provide the necessary basis for the formulation of China's semiconductor lighting standards. And as an advanced public testing platform, it should also track and participate in the formulation of international standards, and test and compare with internationally recognized testing institutions to improve the quality, testing capability and authority of China's semiconductor lighting products, so that China's semiconductor lighting industry Really in line with international standards. In the current domestic situation, the platform construction model can be taken by the relevant government departments, relying on universities or scientific research institutions, and encouraging enterprises (especially large enterprises) to participate in the construction, so that all parties involved in the platform construction can complement each other. It is authoritative, impartial, advanced and realistic. As a public testing platform, it should be open after the completion, and intellectual property can be shared: First, it can serve enterprises in the surrounding areas. With the improvement of the platform construction, its services should benefit the entire semiconductor lighting industry within and outside the province and even the whole country. . II. Status of the construction of the public inspection and evaluation platform for semiconductor lighting in Xiamen In 2006, China mainly launched the construction of three public inspection platforms for the semiconductor lighting industry: Xiamen Semiconductor Lighting Inspection and Certification Center, and Shanghai Semiconductor Lighting Engineering Technology. The research center "[5] and the "Semiconductor Lighting Evaluation System Construction" of the National Semiconductor Device Quality Supervision and Inspection Center [6]. Among them, “Xiamen Semiconductor Lighting Inspection and Certification Center” and Shanghai “Semiconductor Lighting Public Testing and Evaluation Platform” were supported by the establishment of the National 863 Program Semiconductor Lighting Project in 2006. According to the overall goal, strategic positioning and research and development direction of the national semiconductor lighting project of the “Eleventh Five-Year Plan”, all public inspection platforms have formulated their own construction goals, construction contents, operation management mechanisms and service purposes. (I) Xiamen Semiconductor Lighting Inspection and Certification Center was established. Xiamen City was one of the first batch of approved national semiconductor lighting engineering industrialization bases in 2004. Xiamen and its surrounding areas have taken initial shape in the semiconductor and lighting fields. A relatively complete industrial chain in the upper, middle and lower reaches. Well-known enterprises have the largest investment in epitaxial materials and chip manufacturing companies in China, Sanan Electronics, Hualian Electronics, the largest LED packaging and application company in the country, and Tongshida, an internationally renowned company. The Xiamen Municipal Party Committee and the Municipal Government attached great importance to the semiconductor lighting industry and participated in the “National Semiconductor Lighting Project” with great enthusiasm. The Municipal Emerging Industry Office organized the “Xiamen Semiconductor Lighting Industrialization Base Development Plan”. In 2006, the LED night scene project of Xiamen Spring Festival successfully played a role in demonstration and driving. Many cities and even foreign cities in the country came to Xiamen to learn from it, which also promoted the development of LED enterprises in Xiamen and surrounding areas, and launched the application market of LED products. Often, the establishment of Xiamen's semiconductor lighting public inspection platform is conducive to the long-term development of the semiconductor lighting industry in Xiamen and surrounding areas. (II) Construction objectives and service tenet of Xiamen Semiconductor Lighting Inspection and Certification Center Under the joint efforts and coordination of relevant departments of Xiamen City, Xiamen City was established through planning, research and system construction planning from 2004 to October 2006. The Semiconductor Lighting Inspection and Certification Center, the center's construction goal is to establish a domestic first-class, internationally advanced semiconductor lighting and related product testing and certification center, which is expected to be basically completed in 2008. After the completion of the testing and certification center, the test results can be verified with the test results of domestic and international advanced testing centers, providing a testing and R&D platform for the sustainable development of semiconductor lighting industrialization, and better serving the entire industry. Its services include: mastering the quality and development of semiconductor lighting products, providing advice on the government's plan to develop the semiconductor lighting industry, providing a public testing service platform for enterprises, focusing on semiconductor lighting, including LED epitaxial wafers, chips, and related materials. , device and application product testing, testing services include type testing, arbitration testing and domestic and foreign product testing comparison analysis; actively track and strive to participate in international work or national semiconductor lighting related technical standards and testing methods research and development, launch new standards Training, promotion and communication with new testing technologies; establishing cooperation or licensing relationships with international certification bodies and well-known companies; providing technical consulting and services for enterprises to apply new materials, new processes, new products and calibration traceability; Technical talent and research talent base.
