摘要
近年来,由LED-R9显色指数问题引出一系列关于国际照明学会(CIE)原CRI(color rendering index)体系的讨论和修正。CQS(Color Quality Scale)、GAI(Gamut Area Index)、CFI(Color Fidelity Index)等指标相继提出。这些指标的提出结合了一定的视觉评价实验及理论假设的推导和算法。显色指数既能评价光源,也能评价照明。然而,现实照明环境下表现色彩的能力与环境光谱能量分布、照明水平、视觉状态均相关,显色指数并不能反映真实光环境的色彩表现能力,而仅是特定光谱能量分布光源或灯具的特征参数。
In recent years,a series of discussions and revisions on the original CRI(Color Rendering Index)system of CIE of the International Institute of Illumination have been brought out by the problem of LED-R9.CQS(Color Quality Scale),GAI(Gamut Area Index),CFI(Color Fidelity Index)and other indicators have been proposed.In 2017,a technical report,CIE 2017 Colour Fidelity Index for accurate scientific use,was officially launched.These indicators are combined with some visual evaluation experiments and theoretical hypothesis deduction and algorithm.Gradually,let’s step into a blurred zone:the color rendering index can evaluate both the light source and the lighting.However,the ability of color expression in real lighting environment is related to the spectral energy distribution,lighting level and visual state of the environment.The color rendering index can not reflect the color expression ability of the real lighting environment,but only the characteristic parameters of the light source or lamps with specific spectral energy distribution.
