摘　　要：以照明光源暗视觉与明视觉之比(S/P)和背景亮度为参数,利用反应时间法对明视觉和暗视觉的光视效能最大值进行修正,获得了计算中间视觉条件下光视效能最大值的计算式;同时从人眼对光辐射的视感觉程度与亮度对数值近似成正比出发,推导出了相应的中间视觉时光视效能最大值表达式,并对二者进行了比较。最后建议对于道路照明计算应采用由反应时间法获得的光视效能最大值计算式。Maximum spectral luminous efficacy of photopic and scotopic vision was modified with reaction time method, by taking scotopic to photopic （S/P） luminous flux ratios of light sources and background luminance as parameters, and equation for calculating maximum spectral luminous efficacy under mcsopic conditions was proposed . Then another equation for calculating maximum spectral luminous efficacy under mesopic conditions was derived based on the conclusion of that the perceived luminance of radiation is in proportion to logarithmic value of luminance, and the comparison of the results from the two equations was given. At last, it was proposed that equation derived from reaction time should be used in road lighting calculation.
