摘要
道路照明是城市光污染的重要来源。近几年发展的配光技术已经能够比较自如地控制路灯的配光分布,但遗憾的是目前国内大部分路灯照明设计均没有严格按照国际照明委员会推荐的方法进行,未考虑路面本身的光反射特性、即亮度系数。本文讨论了如何结合路面本身的表面反射特性来优化路灯配光设计,提高道路照明质量,节约能源并减少光污染。
Road lighting is one of the main sources of light pollution. The recent technical progress in non- imaging optical design enables the light designers can control the light distribution of road lighting ably.However,very few road lighting designers in China follow the recommendations of the Commission Internationale de L 'Eclairage( CIE) strictly now. The light reflection property of the road pavement,namely,luminance coefficient is not considered in the road lighting design. This paper discusses the method of optimizing the road lighting to improve the illuminating quality,minimize energy consumption and reduce light pollution based on the road luminance coefficient.
