一、光源的色温1.光源的色温和相关色温根据普朗克定律,一个绝对黑体被加热时,它的表面(按单位面积)所辐射的光谱能量的大小和分布完全决定于它的温度。黑体在不同温度时的光谱能量分布见图1,也可按下面的普朗克公式进行 1. Color Temperature of Light Source 1. Color Temperature of Light Source and Related Color Temperature According to Planck’s law, the size and distribution of the spectral energy radiated by its surface (per unit area) depends entirely on its temperature when an absolute blackbody is heated. The spectral energy distribution of the blackbody at different temperatures is shown in Figure 1, which can also be performed according to the following Planck’s formula
