摘　　要：照明光源的光谱分布对人眼辨色能力具有重要影响,即使在相同照度和色温条件下,如果光谱分布存在差异,人眼辨色能力也不尽相同。光源的色温和照度对人眼辨色能力的影响已经有了诸多研究。然而,对LED光源形成的同色异谱光环境对人眼辨色能力的影响尚未见系统研究。本文基于孟塞尔FM-100色棋视觉评价系统,在色温、照度和显色指数R_(a)均一致的LED照明光环境下进行同色异谱照明环境视觉评价。结果表明,传统显色指数(CRI)并不能完全反映光源的显色性,在特殊显色指数R_(i)高的分区(蓝绿色区),实验中并未呈现出最佳的辨色测试结果。两光环境的光谱在蓝绿色区(即460~520 nm)的光谱缺失,导致了在该波长范围辨色测试结果较差。LED白光光谱的科学调制不仅要关注光效、色温、显色指数等指标,应当更注意各色段的能量平衡以达到最佳辨色效果。The spectral distribution of illumination light source has an important influence on the color discrimination ability of human eyes.Even under the same illumination and color temperature conditions,the color discrimination ability of human eyes is not the same if the spectral distribution is different.There have been many studies on the influence of the color temperature and illuminance of the light source on the color discrimination ability of the human eye.However,the influence of the metamerism environment formed by LED light source on the color discrimination ability of human eyes has not been systematically studied.In this paper,based on the FM-100 color chess visual evaluation system,the visual evaluation of the same color and different spectrum lighting environment is carried out in the LED lighting environment with the same color temperature,illumination and color rendering index.The results show that the traditional color rendering index(CRI)can not fully reflect the color rendering of the light source.In the region with a high special color rendering index R_(i)(blue green area),the experiment did not show the best color discrimination test results.The spectrum of the two light environments is missing in the blue-green region(i.e.460 nm-520 nm),resulting in poor color discrimination test results in this wavelength range.The scientific modulation of LED white light spectrum should not only pay attention to the indexes such as light efficiency,color temperature and color rendering index,but also to the energy balance of each color segment to achieve the best color discrimination effect.
