Second, the technology status abroad
1. Highway Tunnel Lighting Research Status
At present stabling highway tunnel reached more than 1000 kilometers, and at a rapid pace. But highway tunnel lighting system installation is very small, not large set lighting or the lighting system is not used, so the lighting quality is very low.
China& acute;s highway tunnel lighting research started late, poor foundation, particularly in-depth research on tunnel lighting requirements and characteristics of extremely lacking, there is a design, manufacturing a wide gap between the lamp and abroad. In recent years, although a few units, Fudan University, Shanghai Institute of lamps, Chongqing Communications Research and Design Institute, Zhejiang Traffic Planning and Design Institute has research conditions and certain test equipment, pay attention to lighting research tunnel, most highway tunnel lighting fixture manufacturers do not study conditions and test equipment, developed tunnel lighting is poor. Domestic tunnel lighting plant, mostly small factories or other areas mainly engaged in the production of lighting equipment, technology, technology and equipment behind, producing scattered, low level of professionalism, efficiency is not high.
