October 11, the Ministry of Industry and Information Technology Electronics Expert fourth Institute (CESI), Osram, Philips, China Sethi (Guangzhou) laboratories and other institutions LED car lights seminar held in Beijing. The meeting discussed in detail the technical requirements of the LED module for the vehicle lamp, covering the key parameters of the luminous flux, color temperature and spectral spatial distribution, and determined the basic direction of the research on the rapid detection and verification of the LED lamp. At present, LED light source module has been widely used in automotive lighting , the core technology has been in the hands of a handful of giants such as Osram, Philips, Nichia, especially automotive headlamp technology. Although there are many domestic package manufacturers to develop a car with LED light source module, but most are concentrated in the brake lights, direction lights and interior lighting in the technical threshold higher headlamps difficult to accomplish. In the study of the performance requirements of LED headlamp light sources, a large amount of research work has been done on the standards development, testing and inspection authorities such as the CESI of the Ministry of Industry and Information Technology and the laboratory of China's Sai-chi (Guangzhou) He has published in the core periodicals of the national electronic information industry standardization, such as "Research on the Safety of LED Vehicle Headlamp Radiation", "Discussion on the Color Rendering Requirements of LED Headlamp Light Sources for Automobiles" and other monographs, for the standardization and rapidity of automotive LED light source modules Detection technology has laid the foundation for the study.
