China has developed the world's leading LED light source
At the Cross-Strait LED Forum held in Xiamen on the 15th, the National Semiconductor Light-Emitting Device (LED) Application Product Quality Supervision and Inspection Center detected that China has developed an LED light source with an input current of 20mA and a COB package mode of up to 177 lumens per watt. This marks that China's LED light source research and development technology has reached the world's leading level. According to reports, this world-leading LED light source uses the MCOB packaging technology with independent intellectual property rights developed by the Haixi Research Institute of the Chinese Academy of Sciences and Fujian Wanbang Optoelectronics Technology Co., Ltd., and the high-efficiency chip prepared by Sanan Optoelectronics Co., Ltd. High-efficiency phosphor prepared by Sichuan Xinli Light Source Co., Ltd. Peng Wanhua, secretary general of the Fujian Optoelectronics Industry Association, said that the successful development of 177 lumens/watt LED light source is of great significance. This means that China's packaging technology, chips and raw materials have reached the world's advanced level. If the technology is used in lighting, it will greatly improve the energy-saving effect and help to promote the industrial upgrading of the industry. He Wenming, chairman of Wanbang, said that LED technology is constantly evolving, and higher-efficiency LED light sources are still being developed.
