摘要
针对人眼中间视觉生理特征, 研究了LED道路照明光源显色性评价方法。通过构建人眼中间视觉下的光视光效模型, 获得了相应的光谱光视效率曲线和人眼敏感波长范围, 给出了基于中间视觉的LED道路照明光源显色性评价及计算方法, 建立了综合显色指数与光源主波长的函数关系式, 并采用主观实验法和客观清晰度计算法进行了验证。计算与实验结果均表明, 在满足道路照明亮度的条件下, 当道路照明光源的主波长为548.5nm时, 光源的综合显色指数最大, 显色性能最佳。
Abstract
For physiological characteristics of the mesoptic vision of human eyes, the evaluation method of the color rendering of LED road lighting power was studied. By constructing the luminous efficiency model in mesoptic vision of human eyes, corresponding spectral luminous efficiency curve and sensitive wavelength range of human eyes were obtained, the evaluation and calculation methods of color rendering of LED road lighting power based on mesoptic vision were given, the functional relationship between the intergrated color rendering index and the dominant wavelength of the light power was established and verified by the subjective experiment and objective definition calculation. Calculation and experimental results indicate that under the condition of meeting the road illumination brightness, the intergrated color rendering index of the light power reaches the largest when the main wavelength of the road lighting power is 548.5nm, and the intergrated color rendering performance is the best.
