摘要
低位照明中眩光强烈程度与灯具出光效率呈正相关,消除眩光的截光板会降低灯具出光效率.从照明方式与灯具结构两个方面展开研究,通过分析路面反射模型,论证路灯出光角度与照明效率的关系.利用软件模拟灯具结构,探讨透镜出光面光线分布、结构中垂直角、出光面高度与灯具长度等因素对灯具出光效率的影响.结果表明,粗糙路面采用正向照明,光滑路面采用逆向照明,可以提高路面反射效率;提升灯具出光效率的关键在于降低透镜出光面高度,当透镜出光面高度为7 mm时,灯具出光效率达到极限值的67%,灯具能耗比国家标准1 W/m^(2)降低了88%.
The intensity of glare in low-level lighting is positively correlated with the light output efficiency of lamps.The light intercepting plate to eliminate glare will decrease the light output efficiency of lamps.In this paper,we investigate the road lighting efficiency from the lighting mode and the lamp structure.Through the analysis of the road reflection model,we demonstrate the relationship between the different light-emitting angles of street lamps and the lighting efficiency.Using software to simulate the structure of the lamp,we discuss the influence of the light distribution of the light-emitting surface of the lens,the vertical angle in the structure,the optical surface height of lens and the length of the lamp on the light-emitting efficiency of the lamp.We find that the use of forward lighting on rough roads and the use of reverse lighting on smooth roads can greatly improve the reflection efficiency of the road.The key to improve the light output efficiency of lamps is to reduce the optical surface height of lens.When the optical surface height of lens is 7 mm,the light output efficiency of lamps reaches the limit value of 67%,and the energy consumption of lamps is 88%lower than the national standard of 1 W/m^(2).
