首先了解一下“色温”这个概念。色温:色温是表示光源光谱成分的一种概念,不同光源所含的光谱成分是用“色温”来表示的,其实是光线颜色的一种标志,而不是指光的冷暖温度。各种不同的光源之所以呈现不同的颜色,就是因为光谱成分不同。色温的计量单位是凯尔文度,并以大写字母“K First look at the concept of “color temperature.” Color temperature: The color temperature is a concept of the spectral components of a light source. The spectral components contained in different light sources are represented by the “color temperature”, which is actually a sign of the color of the light, not the temperature of the light. The reason why different light sources show different colors is because of the different spectral components. The color temperature unit of measure is Kelvin degrees, and the capital letter "K
