LED lights are widely used in highways and tunnels because of their long life, low light attenuation in recent years. The influence of color rendering (CRI) on lighting safety has attracted people's attention as the increase in demand. In this paper, the influence of different CRI on perception luminance of human eyes under different fog transmittance and different luminance was calculated and analyzed. A calculation model of human eye perception luminance considering mesopic vision and fog concentration was proposed. An experiment was conducted by observing different colored targets in a fog chamber. The results showed that yellow targets and high CRI can provide higher perception luminance and the latter is recommended for tunnel lighting in interior zone.
