摘　　要：中间视觉状态下的人眼视觉功效研究对评价中间视觉情况的下的视觉作业效率尤其是夜晚道路照明状况有着至关重要的意义;高色温高显色性LED与常规的低色温高压钠灯相比是否具有优势,尚缺乏足够证据。而中间视觉状态下照明应用的视觉功效是评价光源产品的重要途径。本文试图在中间视觉条件下建立模拟实际效果的道路照明仿真测试场景,对比高色温和低色温两种照明条件下的目标识别速率,以期对探讨LED在中间视觉条件下照明应用的视觉功效,及其与低色温光源在实际应用中的优劣比较提供具有实验性结论。The visual efficiency of human eyes under the mesopic vision circumstances is one of the most important research issues on the assessment of visual effect under the same states especially in road lighting.By now different ways have been studied to test and prove that which one,high and low color temperature lamps,can help to provide higher visual efficiency and recognition probability.The paper gives a method for this purpose via testing the target recognition speed in a simulating scene in computer screen.This scene is constructed to match the lighting features of a real road,and meet the mesopic vision condition,with the options of high and low color temperature.Test results give the comparison of visual effect under high and low color temperature in road lighting,which is helpful for the choices of high luminous efficacy LED lamps..
