Recently, the reporter learned from the Dongguan Science and Technology Department, Tsinghua University State Key Laboratory on Integrated Optoelectronics, Professor Luo Yi as the head of the Guangdong Dongguan Kingsun Optoelectronic Co., Ltd. jointly developed a new type of LED (light emitting diode) lighting of urban roads breakthrough technology Bottleneck, making the actual illumination of LED lights approximately rectangular distribution, uniform illumination, road use than the current comprehensive energy-saving high-pressure sodium lamps up to 60%. The project has recently been listed as national key new product plan, and was listed as key projects in Guangdong Province, and green products projects.
According to reports, the traditional high pressure sodium lamps often used, the existence of the uneven distribution of illumination, the illuminated object color distortion, glare serious, life is short, high maintenance and other shortcomings, the overall polishing efficiency is low. Power type LED used for lighting the special problems of urban roads, Tsinghua University, State Key Laboratory on Integrated Optoelectronics Research Group Professor Luo Yi set up a technology research group, in the LED lights on the optical system and cooling structure of a major breakthrough, obtained with Proprietary high light extraction efficiency, rectangular uniform distribution of power type LED illumination optical system package. After testing, single white LED power-based road use than the current comprehensive energy-saving high-pressure sodium lamps up to 60%.
Dongguan Kingsun Group and Tsinghua University, Tsinghua University successfully with independent intellectual property rights owned power type LED package and the application of technology implementation industrialization. Meanwhile, both sides jointly in high-efficiency, high reliability and intelligent cluster LED driver technology, a unique LED lamp assembly manufacturing industry has made significant progress in technology. Currently the new lighting products have been successfully applied Changping Town, Dongguan City, Guangdong Province, Guangdong Science Center and Tsinghua University Gymnasium in the street lighting, and achieved good energy saving and lighting effects.
It is estimated that if the country's roads are high-efficiency lighting, new LED lights, the annual saving of 42 billion kWh of electricity, equivalent to saving 15.8 million tons of standard coal, close to several large production of coal a year.
