Tested by the National Semiconductor Light-Emitting Device (LED) Application Product Quality Supervision and Inspection Center, the input current of the LED light source developed by Fujian Wanbang Optoelectronics Co., Ltd. and the Chinese Academy of Sciences Haixi Research Institute is 20MA luminous efficiency of 261 lumens per watt (lm/w).
According to the investigation report provided by Fujian Science and Technology Information Research Institute, the luminous efficacy of the LED light source exceeds the luminous efficiency index of the LED light source publicly reported in the literature at home and abroad. This is another major breakthrough in the development and promotion of high-efficiency LED lighting products in Fujian.
He Wenming, chairman of Wanbang Optoelectronics Co., said that the product uses the materials developed by the Institute of Material Structure of the Chinese Academy of Sciences and the unique process technology of the Wanbang MCOB package. It has independent intellectual property rights; it has been industrialized and the production cost is lower than that of similar products. The future can be introduced to the market on a large scale.
