New tunnel lighting LED light source

Tunnel lighting can improve road conditions in the tunnels, improve tunnel vision to reduce driver fatigue, help to improve the traffic capacity of the tunnel to ensure traffic safety. As a new generation of LED light source lighting, with its advantages of high efficiency, energy saving and environmental protection from the State and local government support and promotion. Its application areas are gradually moving from a signal indicating lighting, emergency lighting and other small power extended to street lighting and road tunnel lighting and other high power LED lighting. Tunnel lighting, LED light sources in addition to its good optical properties, but also has to improve tunnel lighting quality, intelligent control and easy maintenance-free advantages, this LED light source applied in tunnel lighting brings good opportunities. But at the same time, LED light sources in the current tunnel lighting is still suffering from high prices and major challenges in heat two, as well as the challenges of LED lighting technology is not yet mature.
