The paper adopts DIALux software to establish the tunnel model, undertakes the simulation experiments for the vision features in the LED lights at different color temperatures and high pressure sodium, and evaluates the light source with the optimal vision features, so as to pro-vide some reference for the selection of the light source in tunnels.%采用DIALux软件建立隧道模型，在不同色温的LED灯和高压钠灯光环境下，进行针对视觉特性的模拟实验，评价出视觉适应性最佳的光源，为隧道内光源选择提供参考依据。
