LED package magic "surface light source" lighter and more energy efficient

Yan Guohua, general manager of Nanjing Xiongyan Optoelectronics Technology Co., Ltd. in the National University Science and Technology Pioneer Park of Nanjing University of Technology, said, “The light source is actually a luminous body.” Yan Guohua pointed to a circular sheet at the lamp head, saying that this small wafer is like a mini. CD, less than 4 cm in diameter, less than 1 mm thick, with a yellow background. Look closely, there are small black spots on it. “Actually, every little black dot is a tiny illuminator.”

This technology was jointly developed by Lu Hanxiong, a member of the Hong Kong Institution of Engineers, and Nanjing University of Technology. Both the light source chip and the driver chip have their own intellectual property rights. It is understood that the Asian Youth Club will be held in Nanjing next year, and the athletes' dormitory in Pukou District is also expected to use the "surface light" lamp.
