1. The color rendering ability of the light source to the object is called color rendering, which is a reference or benchmark light source (incandescent lamp or painting light) with the same color temperature of the fruit language. The spectral content emitted by the light determines the light color of the source, but the light color can also be made by many, a few or even only two monochromatic light waves, and the color rendering of each color is also very different.
2, the same light color of the light source will have different spectral composition, spectral composition of the light source is more likely to provide better color quality. When there is little or no main wave reflected by the object under the reference light source in the light source spectrum, the color will produce a significant chromatic difference. The greater the degree of color difference, the worse the color rendering of the light source. Color rendering index is a common method to define the color rendering evaluation of light source.
