The reporter saw a magical "surface light source" at Nanjing University of Technology a few days ago. Compared with the common LED "point light source" on the market, it not only saves 20% of electricity, but also can be ten times brighter at the same wattage. Up to 30,000-50,000 hours.
Bian Guohua, the general manager of Nanjing Xiongyan Optoelectronics Technology Co., Ltd. in the National University Science and Technology Pioneer Park of Nanjing University of Technology, told reporters that "the lamp source is actually a luminous body." The film is like a mini CD, less than 4 cm in diameter and less than 1 mm thick, with a yellow background. Look closely, there are small black dots on it. "Actually, every little black dot is a tiny luminous body."
This technology was jointly developed by Lu Hanxiong, an academician of the Hong Kong Institution of Engineers, and Nanjing University of Technology. Both the light source chip and the driver chip have independent intellectual property rights. The Asian Youth Games will be held in Nanjing next year, and the athletes ’dorms in Pukou District are also expected to use" surface light source "lights.
