Intensive LED national standards still need to be tracked and improved

Author Liang Hongbing

Standards have always been the focus of the LED industry. Since December last year, industry standards have been announced and will be implemented this year. First, the Ministry of Industry and Information Technology approved the release of nine industry standards covering LED materials, chips, devices and related inspection and testing methods. Subsequently, the National Standardization Administration issued six LED-related products led by the National Lighting Standardization Technical Committee. The standard, together with two mandatory national standards previously issued, totals eight. The introduction of a series of new standards will help promote the development of China's LED industry and technological innovation, while promoting the more standardized and healthy development of the LED lighting industry.

The new standard is coming out

The lack of standards has always been the bottleneck in the development of the LED industry. The call for the introduction of national standards as soon as possible has also been called for many years. At the beginning of the new year, we saw that nine industry standards covering LED materials, chips, devices and related inspection and testing methods have been approved by the Ministry of Industry and Information Technology and officially implemented on January 1. Subsequently, the National Standardization Administration Committee also promulgated the "People's Republic of China National Standards Approval Announcement No. 15 (No. 155)". The announcement shows that the six LED-related standards submitted by the National Lighting Appliance Standardization Technical Committee have passed the examination and approval and become the national standard. Together with the two mandatory national standards previously introduced, a total of eight. These eight standards have been implemented since April this year.

As a standard research and development unit, the Semiconductor Lighting Technology Standards Working Group of the Ministry of Industry and Information Technology has done a lot of work since its establishment in 2005. Based on the needs of market and industrial development, the working group actively carried out research and development work on the technical standards system of the semiconductor lighting industry. After years of hard work, the working group has made breakthroughs in semiconductor lighting materials, chip technology, packaging product testing and testing methods. It is precisely because of years of accumulation that we have seen "Detailed Specifications for Power LEDs for Semiconductor Optoelectronic Devices", "Semiconductor LED Test Methods", "Sapphire Substrate for Gallium Nitride Based Light Emitting Diodes", "Semiconductor Light Emitting Diodes" "Phosphors", "Technical Specifications of Power Semiconductor Light-Emitting Diode Chips", "Test Methods for Semiconductor Light-Emitting Diode Chips", "Detailed Specifications for Small Power LEDs for Semiconductor Optoelectronic Devices" and "Semiconductor LED Product Series" and "Semiconductor Lighting" The publication and implementation of nine industry standards including terminology.

It is not difficult to find that these nine industry standards cover various fields such as LED materials, chips, devices and related inspection and test methods. Among them, "Phosphors for Semiconductor Light-Emitting Diodes" stipulates the performance requirements and test methods for phosphors for white light-emitting diodes. , inspection rules and signs, packaging, transportation, storage and Other content. This standard is not included in the newer nitride phosphors, considering its technology and production, which fully reflects the principle that the standards should guide the industry, service industry and standard industry.

As the emerging green environmental protection lighting industry, semiconductor lighting is currently facing the biggest problem, which is the lack of national standards and industry standards, resulting in market confusion. In addition to the nine basic standards approved by the Ministry of Industry and Information Technology and officially implemented, the National Standardization Administration has also promulgated six LED lighting standards led by the National Lighting Standardization Technical Committee, plus two mandatory National standards for a total of 8 relevant standards for LED lighting. The standards issued by the National Standards Committee mainly focus on the lighting industry.

The standard service industry is constantly improving

The introduction of new standards will help to promote the development of China's LED industry and technological innovation is undoubted, especially for the semiconductor lighting industry to achieve the survival of the fittest, to guide the industry into an orderly, standard state, to promote the health of the LED lighting industry The development of the land has played a very good role in regulation.

For the introduction of a series of industry standards, the reporter also learned in the interview that enterprises still have doubts about whether these standards can truly become the guiding principles for enterprise production. Peng Wanhua, secretary general of the Fujian Optoelectronics Industry Association, believes that the performance requirements of LED application products are constantly changing and improving, and the products are not yet mature, so it is difficult to formulate appropriate LED application product standards.

Professor Liu Muqing, director of the Institute of Electric Light Sources at Fudan University and director of the Department of Electric Light Sources, stressed in an interview with China Electronics News that the LED industry is an emerging developing industry, and domestic and international standards are being formulated. Therefore, no It should be a “development” standard, but a 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. The localities standardize the corresponding requirements according to the local roads and climate characteristics. They are also a good complement to the national standards. Through local practice, we constantly find that the problems are continuously improved, and the local standards or standards are continuously improved. It is very important to promote and improve the national standards. meaningful.

Li Mantie, general manager of Shenzhen Lehman Optoelectronics Technology Co., Ltd. said that the development of LED standards needs to be gradual. LED is an emerging industry. The establishment of standards requires a process. Many LED products have not yet been finalized, and technology is also developing rapidly. Therefore, LED standards can be formulated step by step and according to the development progress of the LED industry. (China Electronics News)
