recently, the reporter understands from dongguan city department of science, tsinghua university, state key laboratory of integrated optoelectronic se professor, director of the research and development of new type of light emitting diode city road lighting light breaks through the technical bottleneck, make the actual illuminance distribution of LED street lamp approximately rectangle, intensity of illumination distribution even, than the current path using high pressure sodium lamp energy saving more than 60%. The project has been listed as national key new product plan, is listed as key construction projects and green products in guangdong province. According to introducing, traditional street lamps with high pressure sodium lamp, the downside is uneven distribution of lighting, according to the objects color distortion, glare, short service life, high maintenance rate, low luminous efficiency as a whole. For power leds in the special problems of the application of city road lighting, tsinghua university professor of state key laboratory on integrated optoelectronics se group has set up a technology research team, in the optical system of the led street light and heat dissipation structure made significant breakthrough, obtained with independent intellectual property rights, higher light efficiency and rectangular uniform illumination distribution of power leds encapsulation optical system. Tests have shown that a single power white light-emitting diodes (leds) than on the road at present using the high-pressure sodium lamp energy saving more than 60%. Guangdong dongguan tain is group and common successful industrialization of the tsinghua university, tsinghua university with independent intellectual property rights of power led packaging technology. At the same time, the two sides in high efficiency, high reliability, intelligent cluster light-emitting diode drive technology and unique industrialization led street lamp assembly manufacturing technology on major progress was made in common. At present, this new type of lighting products has been successfully used in changping town, dongguan city, guangdong science center, and tsinghua university gymnasium of road lighting, lighting energy saving effect is good. It is estimated that if the nationwide will be efficient and new type led street lamp used in road lighting, can save power 42 billion kilowatt-hours a year, equivalent to 15. 8 million tons of standard coal, close to several large street lamps lighting the coal mine production.
