七、CIE标准照明体和标准光源 由于物体的色调与照明光源的光谱组成有关,为统一颜色的测量和计算,CIE规定了标准照明体与标准光源. 1.光源的色温:光源的颜色决定于其光辐射功率按波长的分布,即相对光谱功率分布.为统一评价光源,取绝对黑体的光色为标准.黑体的光谱功率分布仅决
CIE standard lighting body and standard light source Because of the color tone of the object and the spectral composition of the lighting source, in order to unify the color measurement and calculation, CIE provides the standard lighting body and the standard light source 1. The color temperature of the light source: The color of the light source is determined by The distribution of the optical radiation power by wavelength, that is, the relative spectral power distribution for uniform evaluation of light source, take the absolute blackbody light color as the standard blackbody spectral power distribution only
