摘要
通过论述在中间视觉下道路照明中应用的不同光源、不同色温光源对人眼的反应时间,反应时间与背景亮度、亮度对比和视标偏心角的关系,及中间视觉下道路照明用典型光源的光谱光视效率,提出人眼在中间视觉状态下的光谱响应特性不同于明视觉状态下的光谱响应特性,应使用反应时间对人眼的视觉功能进行评价;中间视觉条件下照明的节能设计不能单纯从光源的发光效率考虑,还必须考虑到人眼的视觉功效及人的反应时间,这对照明节能设计有直接的指导意义.
This paper studies the reaction time of different kind of light source and different color temperature light sources of road lighting on mesopic level , and the relationship between reaction time and background Luminance,visual target contrast ,visual target eccentric angle,and the relative luminous efficiency function of the typical light source of road lighting. It advance the difference between action spectra on mesopic vision and hotopic vision ,it also has elaborated the use of the reaction time to evaluate the visual performance of eyes. The lighting energy saving design on mesopic level should considers not only the luminous efficacy of the light sorce,but also the visual efficiencies of eyes and reaction time of eyes. That means a lot to the lighting energy saving design
