Abstract：Aiming at the problem of high energy consumption of tunnel lighting , a lighting solution for the first half of the entrance section of tunnel used by reflected sunlight is proposed .Based on the calculation method of solar radiation and the spectrum of solar radiation intensity, the relation between luminous flux and solar radiation intensity irradiated to the reflector is analyzed .Taking the distribution of solar radiation intensity in a specific area of Guizhou for example , the reflector system size, which is used for tunnel lighting based on reflecting sunlight, is deduced.From the point of utilizing light energy and system size, the feasibility of lighting the first half of the entrance section of tunnel by reflecting sunlight is illustrated.
