道路照明的精确计算

Accuracy Calculation of Lighting for Roadways

道路照明的照度和亮度计算的传统方法已不能适应道路照明设计的要求。本文采用精确的逐点方法求得整个场地域的照度和亮度。本方法可以处理群灯及不同光源的照明计算,在高速公路及南浦大桥使用中取得满意效果。

The empirical calculation of illumination and luminance is not sufficient for modern roadways. In this paper, the point by point method for calculating the illumination and luminance in the specified field is presented. This method can be used in the series of lighting or different light sources and had good results on highways and the Shanghai Nanpu Bridge.
