摘　　要：隧道中间段属于中间视觉范畴,利用三种中间视觉模型分析LED色温对中间视觉亮度的影响规律。结果表明,在隧道照明中间段,LED能使人眼获得更高的实际感知亮度,且色温越高,亮度增益越大;环境亮度越高,增益越小。根据中间视觉模型对隧道中间段照明亮度设计进行修正,可节省照明能耗8%~28%。在1~3cd/m^2范围内,MOVE模型计算的中间视觉亮度最大、MES2次之、S模型最小,MOVE模型采用有色差的视觉任务,其试验条件更符合隧道实际行车环境。The interior zone of tunnel belongs to the mesopic domain. In the present study, 3 types of mesopic model are employed to analyze the influence of LED color temperature on lighting luminance. Results show that, LED can facilitate higher perception brightness for people in the interior zone, and the higher the color temperature of LED is, the higher perception brightness people can obtain. Lighting luminance design modified by the mesopic models can save 8% - 28% energy consumption. With the range of 1 -3cd/m2 ,luminance calculated by MOVE ranks the highest, followed by MES2 and S model. Adopting the achromatic visual task, MOVE model is more accordance with the actual tunnel driving en- vironment.
