Abstract:

The conventional tunnel lighting methods have such disadvantages as high operation cost and high energy consumption. In the paper, the design of the conventional tunnel lighting methods is optimized by using shading shed and solar LED lighting, the section division and transmittance of the shading shed are discussed on basis of visual adaptation, the methods for the calculation of the length of the shading shed are proposed on basis of the economic efficiency of the shading shed, and finally the calculation methods for the solar LED lighting, the battery capacity and the power of the solar cell matrix are presented. 

Key words: highway tunnel, tunnel lighting, shading shed, length of shading shed, calculation model, solar LED lighting
