Application of road lighting in Shanghai LED

Learned from the 2011 Chinese International LED Industrial Technology Exhibition and forum reporter recently, Shanghai is vigorously promoting the gradual promotion of green lighting, LED street lamp. Among them, the Yanan east road tunnel, the upper middle road tunnel and part of the subway platform will be the first to use.

"Energy saving is the biggest benefit of street lamp upgrade. "Comprehensive assessment of Shanghai semiconductor lighting Engineering Research Center Manager Li Shuzhi said that an ordinary high pressure sodium lamp power is about 400W, and the LED lamp also need only 150W, in order to calculate the current Shanghai city about 300000 street lamps, a year can save considerable power. In addition, compared with the traditional street lamp, LED street lamp has the advantages of energy saving, controllable and long service life. The traditional street light suddenly light is easy to reduce the life of lamps, LED lights do not have this concern. In addition, the traditional street lamp, road monitoring camera shoot something is likely to be black, and installed LED lights, camera is very clear, this to the police investigation has also brought great convenience.

At present, the application of LED street lamps in Shanghai is still small-scale pilot, the entire section of the Yangtze River Bridge and Wuning Road, flowers and trees on the road sections have been in use. Li Shuzhi admitted that in the actual use of the researchers found that the presence of LED street lamp luminous efficiency needs to be improved, it is difficult to overcome the problem of high temperature and pollution, high cost. In addition, there is no standard interface also led to the major producers of LED lighting products, difficult to unify.

Li Shuzhi said that the current 3 meter low lever LED street lighting technology has matured, but the installation of LED street lamps in the elevated road has not yet found the right object". Last year, Shanghai completed the "rail transit vehicle and platform height lamp system and its large scale application" and "elevated road lighting research and development" and other research projects, including R & D lighting and street lighting LED tunnel, can realize the light source has an average life of 50 thousand hours. Li Shuzhi said, Shanghai Metro Line 9 carriages, Yanan East Road Tunnel renovation projects have the intention to use LED lights, the specific program is still in development.
