摘　　要：本研究采用视觉功效法,利用自行研制的"反应时间测量系统"测取了人眼在不同色温LED光源下的视觉功效,并由此获得了适用于道路照明的LED光源色温值。为验证其可靠性,又按照常规检测方法、安全视距停车要求及对驾驶人员的主观问卷调查,对采用该色温LED道路照明灯的实际道路照明工程进行了现场检测与调查。结果表明,该道路的各项照明指标满足国家标准和安全停车的视距要求。This study adopts a reaction time measurement system, which developed by ourselves, to measure the visual efficiency of human eyes at different color temperatures LED light sources. The study obtains proper color temperature of LED light source which fits the road lighting best. To verify the reliability, this study follows the conventional detection methods, security line-of-sight parking requirements and drivers＇ subjective questionnaire to detect and investigate the practical road lighting projects which adopt this color temperature of LED road light source. The result shows that lighting indicators of this road meet the national standard and secure parking line-of-sight requirements.

关 键 词：LED 光源色温 视觉功效法 反应时间 光生物效应 道路照明
