摘　　要：本文给出了在中间视觉道路照明条件下光视效能最大值模型。在人眼驾驶行为反应时间模拟系统中选取若干受测者进行实验,通过实验数据推导出基于反应时间的光源主波长和中间视觉背景亮度关系模型。并以该关系模型为基础,给出了中间视觉条件下,基于背景亮度和光源主波长的光视光效能最大值模型。利用最大值模型探讨了光源的节电性能,得出基于中间视觉光视效能最大值的照明功率密度关系函数以及528 nm主波长照明光源的节能性最佳的结论,并结合实验验证了此结论的正确性。A model of the maximum of luminous efficiency underthe human mesopic vision about road lighting is given.The subjects were selected for experiments in the reaction time simulation system of driving behavior, and the relational modelbased on reaction time between main wave length of lighting source and background brightness under the mesopic vision is obtained by experimental data analysis. Based on the relational model, the model of the maximum of spectral luminous efficiency with background brightness and light wave length under the mesopic vision is given.Using this model, the energy saving of road lighting is discussed, the relation function of Lighting Power Density based on maximum of spectral luminous efficiency under the mesopic vision is obtained, and the conclusion is drawn that the energy saving of 528 nm main wave length lighting sourceis best. The correctness of this conclusion is verified by experiments.
