The Research of LED Lights Model Based on Road Lighting in Mesopic Vision

This paper analyzes the structural features of the human eye in the middle of the road lighting visual state of the visual request of road lighting in the Mesopic range of lighting, road lighting standards to build a white and green LED light source distribution model and defines the sharpness of the image according to the model function. In the Matlab7.1 environment, high pressure sodium yellow light LED white light and LED white and green background light, the model simulation analysis of the image clarity, results show that, in the Mesopic same brightness level state road lighting selection white and green the LED light source has better clarity and sensitivity.
