摘　　要：通过分析人眼的视觉结构特点和道路照明亮度标准,提出一种基于三基色的配光模型。对模型的综合验证表明,在相同亮度情况下,R、G、B的三刺激值是呈非线性增大的,并且绿色刺激值最大。通过计算图像清晰度和SP的值,说明LED白绿光用作道路照明效果更佳。Through analyzing the structural characteristics of human visual brightness and road lighting standards, this paper proposes light distribution model based on three primary colors. Through the comprehensive verification of the model, the results show that under the same brightness. R, G, B tristimulus values are non - linear increas- ing, and the green stimulus value max. Then by calculating the image clarity and S/P value, LED white and green source is more suitable for road lighting, to obtain better lighting.
