Our country has developed the highest LED street light with the world's highest luminous efficiency

The Information Bureau of Fujian Province announced on the 28th that China has developed an LED street light with an initial light efficiency of 131.42lm/W, which indicates that the initial light efficiency of the entire LED street light in China has reached the highest level in the world.

"The research results have surpassed all the current domestic and international publicly reported LED fluorescent tubes initial light efficiency index." The report provided by the Fujian Institute of Science and Technology Information, "The current domestic LED lights have the highest initial value of 108.61lm / W. In the international community, there are only LED lights with relatively high light efficiency, and no reference has been made to the overall light efficiency index."

This achievement was jointly developed by the Haixi Research Institute of the Chinese Academy of Sciences and the Fujian Wanbang Optoelectronics Technology Co., Ltd. and Sanan Optoelectronics. The reporter saw from the monitoring report of the National Semiconductor Light Emitting (LED) Application Product Quality Supervision and Inspection Center that the initial light efficiency of the submitted street light reached 131.42lm/W. 

Academician Hong Maozhao, Director of the Institute of Materials Science and Technology at the Chinese Academy of Sciences, said that after continuous research and development, China has invented a highly efficient sidewall etching chip, a BOSS primer with high thermal conductivity and high transmittance, and a unique MCOB package structure that has been independently developed. The surface coating technology lays a solid foundation for the high reliability and high light efficiency of LED lamps, and further reduces the cost through technology integration.

The reporter learned that at present, the street lamp product has realized industrialization, and the production cost is 4-60% of the foreign similar products.
