为了提高道路照明的安全性，实现道路照明的节能，基于光观和光观理论，分别研究了高压钠灯和金属卤化物灯在光观和光观两种照明水平下的发光效率。进行了高压钠灯和金属卤化物灯的反应时间实验。由此得到了金属卤化物灯与高压钠灯的亮度对比系数。结果表明，金属卤化物灯在柠檬酸下的发光效率是高压钠灯的三倍。在高亮度条件下，高压钠灯的发光效率高于金属卤化物灯。由于亮度低，金属卤化物灯的发光效率高于高压钠灯。如果只考虑反应时间，金属卤化物灯在道路照明下的照明效果优于高压钠灯。
In order to improve the safety of road lighting and realize energy saving of road lighting,the luminous efficiencies of high pressure sodium lamp and metal halide lamp under citopic and mesopic lighting level was studied respectively based on the theory of citopic and mesopic vision.The reaction time experiments of high pressure sodium lamp and metal halide lamp were performed.The luminance contrast coefficients of metal halide lamp to high pressure sodium lamp are thus obtained.The results suggest that luminous efficiency of metal halide lamp under citopic is triple of that of high pressure sodium lamp.The luminous efficiency of high pressure sodium lamp is higher than that of metal halide lamp when high brightness.As low brightness,luminous efficiency of metal halide lamp is higher than that of high pressure sodium lamp.The lighting effect of metal halide lamp is better than that of high pressure sodium lamp under road lighting if we consider only reaction time.
