为解决选取隧道照明光源时未考虑光谱能量分布和相关色温因素造成光源选用不当的问题，结合中间视觉模型，对道路隧道常用光源的光谱能量分布和相关色温进行测试研究，分析不同隧道常用光源的光谱能量分布与相关色温关系； 通过引入光谱S/P值的计算方法，从人眼感知角度分析不同隧道常用光源S/P值与相关色温关系。研究表明： 1）LED光源的相关色温随着蓝光比例的增加而增加； 2）不同类型光源的S/P值与光源的相关色温不是一一对应的关系，但LED光源的S/P值随着相关色温的增加而增大； 3）金属卤化物灯、白色荧光灯和LED光源适合应用于隧道照明，但从长远来看，隧道照明选用相关色温较高的LED光源更为合理。

In order to solve the problem of improper selection of illumination source due to spectral energy distribution and correlated color temperature factors when selecting the tunnel illumination source, the spectral energy distribution and correlated color temperature of the common light source of highway tunnel are tested based on intermediate vision model, and the relationship between the spectral energy distribution of the common light source and the correlated color temperature is introduced. The calculation method of the S/P value of the spectrum is introduced. The relationship between the S/P value of the common light source and the correlated color illumination temperature of different tunnels is analyzed from the perspective of human perception. The research results show that: (1) The correlated color temperature of the LED light source increases with the increase of the blue light ratio. (2) The S/P value of different types of light sources does not have a onetoone correspondence with the correlated color temperature of the light source, but the S/P value of the LED light source increases with the increase of the correlated color temperature. (3) The metal halide lamps, white fluorescent lamps and LED light sources are suitable for tunnel illumination, but considering longterm illumination, it is more reasonable to use LED light sources with higher correlated color temperatures.
