In this paper, It evaluated visibility about Metal Halide Lamp(MHL), High Pressure Sodium Lamp(HPS) and PLS(Plasma lighting System) as Road lighting source in fog conditions. To evaluate visibility, it analyzed valuation of subjects about each light sources in special fog conditions. In result, it obtained that High Pressure Sodium Lamp has best visibility in photopic vision and PLS has best visibility in scotopic vision. This result is expected to help about select of Road lighting source. |
