"Surface Illumination" technology makes LED light ten times brighter than the same power light

The reporter yesterday saw a magical "surface light source" at Nanjing University of Technology. Compared with LED "point light source", which is commonly available on the market, not only can it save 20% of power, but it can also light ten times the same wattage, and the average life expectancy can be increased. Up to 30,000 - 50,000 hours.

Nan Jing Xiongyan Optoelectronics Technology Co., Ltd. of Nanjing University of Technology’s Science and Technology Pioneering Park, General Manager Ruan Guohua, told reporters that “The light source is actually a luminous body.” Guo Guohua pointed at a round piece of light at the lamp head and said that this small circle The film is like a mini CD, less than 4 cm in diameter, less than 1 mm thick, and has a yellow background. Observe carefully and there are small dark spots on it. "Actually, every little black dot is a tiny light."

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 independent intellectual property rights. Next year, the Yaqing Club will be held in Nanjing. The athletes dormitory in Pukou District is also expected to use the "face light" lamp. (Reporter Xu Hao)
