从视觉科学理论出发 ,探讨城市道路照明节能方法 ,并建议采用辐射光谱成份中含较多的蓝绿色光的金属卤化物灯作为道路照明光源 ;同时讨论了半柱面照度和路面平均照度等一起作为城市道路照明标准的必要性
Based on the theory of vision science, this paper discusses the energy-saving methods of urban road lighting and proposes to use the metal halide lamp with more blue-green light in the radiation spectrum as the road lighting source. Meanwhile, the half-cylinder illumination and the road surface average illumination are discussed Necessity as a standard for urban road lighting
