WASHINGTON based Tsinghua University developed the new LED (light emitting diode abbreviation) city road lighting breakthrough technology bottlenecks, making the actual illumination of LED lights approximately rectangular distribution, uniform illumination, road use than the current high-pressure sodium lamp Integrated energy-saving over 60%.
High luminous efficiency white LED, and has low production costs, device performance and stability, the market easy to accept, efficient, energy saving, long life, good color rendering index and so on. And efficient production of power type LED lights facing the high optical and thermal technical barriers. Power type LED used for lighting the special problems of urban roads, Tsinghua University, State Key Laboratory on Integrated Optoelectronics, LED street light recently in the optical system and cooling structure of a major breakthrough, obtained with independent intellectual property rights of high light extraction efficiency, uniform rectangular The 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%% or more. 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. The current new lighting products have been successfully applied to the Guangdong Provincial Science Center lighting project, Tsinghua University Olympic venues road lighting, road lighting, Changping Town, Dongguan, Dongguan Shi Pai Town, a comprehensive renovation project nearly ten thousand street-lamp, a Dongguan Shilong Town Comprehensive renovation project more than a street lamp, lighting district, Shenzhen Energy Engineering Meishan Court, Zhongshan Torch Development Zone, New Street Lights, Torch Development Zone, Zhongshan City, city lighting engineering and other high-power LED street lighting project. It is estimated that, if the national road lighting are used efficiently, the new LED lights, you could save 42 billion kWh of electricity, equivalent to saving 15.8 million tons of standard coal, close to several large production of coal a year.
