Debating the wrestling -- Revelation of the application of LED street lamp

In today's global energy shortage environment, energy conservation has become a trend, while the country also vigorously promote energy conservation and emission reduction, LED is its energy saving, long life, environmental protection and other advantages of pollution-free development. High power LED, especially high-power LED street lamps in our country greatly sought after, many companies have invested in this project. But we also want to see its investment costs are too high and difficult to overcome technical barriers still exist. In order to solve the specific problems of outdoor LED lamps and explore the solution, the application of high power LED street light debate will be held on afternoon in Guangzhou Kokusai Hotel. China semiconductor lighting network also sent someone to participate in, and the first time back to the debate on both sides of the scene and the final conclusion.

The main topic of the debate around 1, high-power LED street lamps are currently facing difficulties? 2, high power LED street lighting technology how to solve? 3, the current high-power LED street lamp is only used for government demonstration projects, how to carry out a wider range of promotion? 4, is it appropriate to continue to invest in high-power LED street lamp? Several aspects of development.

The debate in China Institute of lighting transportation director of lighting and light signalling Specialized Committee Song Xianjie, Professor of Tsinghua University, Dongguan KingSun Semiconductor Research Institute deputy director Qian Keyuan composed the Affirmative representative for LED related enterprises and research institutions in charge of personnel, agree with the stage of high-power LED street lamp used in road lighting; indoor lighting lighting to Chinese Institute of Specialized Committee the honorary director Ren Yuan, chairman of the Shanghai Institute of lighting chapter HAICONG composed of the representative for the traditional lighting researchers and street lamp management personnel, they oppose the current high-power LED lamps used in road lighting.

The two sides of the debate, the existing problems of the LED street view, the current LED lamp products uneven in quality and affected by the lighting design, etc., so that the light environment and economic performance is still not satisfactory. Secondly, the high-power LED street lamps and high pressure sodium lamp compared to poor performance in the maintenance, mainly because the supporting system is not perfect. The development of high pressure sodium lamp is comprehensive, and the economy is good.

Square pointed out the advantages of LED street lamps in energy saving, environmental protection, optimistic about the future development prospects of LED. Think LED development speed is very fast, in a few years ago, LED in the application of road lighting is still impossible, but at present our country has formed a more than and 400 km LED street lamp demonstration project, progress is very big. In addition, LED has been greatly improved in terms of light efficiency and stability. For the development of LED street lamp, square also think LED street lamp should keep stable, step by step the pace of development, blind to the development of LED street lamp industry is extremely unfavorable.

After intense discussion, the two sides reached some consensus, agreed that 150W's high power LED street lamp can save energy 20%.
