摘　　要：道路照明属于中间视觉范畴,在这一范围内国内外尚无统一的视觉灵敏度曲线,为了将我们的研究结果应用于道路照明的范畴,本实验采用了近年国际上广泛采用的基于反应时间测量的视觉功能法,以反应时间和目标对比度的关系为切入点,同时引入了背景光谱,视角大小,背景照度和视场偏心角参量,对于反应时间的影响进行分析。其操作采用变量控制的方法进行实验室环境模拟和数据采集。结果显示,反应时间与照度对比度关系是呈指数下降的关系的,同时还获得光谱,背景照度,视角和视标大小等对于反应时间的影响。这些对于研究道路照明,提高道路照明质量都有着积极的意义。Road lighting covers the region of mesopic vision and there is no unified luminance efficiency curve in this region. In this experiment, we used an internationally accepted and applied method, which is based on the measurement of reaction time. We choose reaction time and contrast as the basic factors and incorporate background luminance, visual angle, spectrum and visual eccentricity to study their effects on reaction time. We use programs to control the parameters result indicates that reaction time and effects of other parameters mentioned so as to imitate an environment that can be contrast rate show an exponential declining applied in our projects. The relation. We also study the above on reaction time. These research and results are very helpful in enhancing road lighting quality and for future study
