为了解决传统隧道照明方法运营成本高和能耗高的问题，首先，采用遮光棚和太阳能LED照明对传统隧道照明方法进行优化设计；然后，结合视觉适应性对遮光棚的段落划分和透光率进行探讨，并结合遮光棚的经济性提出了遮光棚长度计算方法；最后，介绍了太阳能LED照明、蓄电池容量和太阳能电池方阵功率的计算方法。

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. 
