LED light source of 261 lumens/watt was born in Fujian, China1

By the National Semiconductor Light Emitting Device (LED) The application product quality supervision and inspection center tested that the input current of LED light source jointly developed by Fujian Wanbang optoelectronics and Haixi Research Institute of Chinese Academy of Sciences is 20MA and the luminous efficiency reaches 261 lumens/watt (lm/w). According to the novelty report provided by the Fujian Institute of Science and technology information, the light efficiency of the LED light source exceeds the light efficiency index of the LED light source reported in the domestic and foreign literature. This is another major breakthrough in Fujian's research and development and promotion of efficient LED lighting products. He Wenming, chairman of Wanbang Optoelectronics, said that the product adopts materials developed by Fujian Institute of material structure of Chinese Academy of Sciences and Wanbang MCOB packaging technology, and has independent intellectual property rights; At present, it has been able to realize industrialization, and the production cost is lower than that of similar products, and it can be introduced to the market on a large scale in the near future.
