Measurement of the relative spectral energy distribution of the light source relative to the light source

With the continuous generation of new light sources, the spectral resolution of the light source becomes increasingly important in the measurement, and the light color characteristics of the light source and their characterization quantities such as color coordinates, color temperature and color rendering index are determined by the spectral energy distribution of the light source , So we need to better understand the spectral distribution characteristics of the light source. The general light source is a compound color light composed of colored lights of different wavelengths. If the intensity of each colored light in its spectrum is measured with a spectrophotometer, the value of the radiation intensity of colored light of different wavelengths can be obtained. This article introduces a method for measuring the relative spectral energy distribution of a light source using an ultraviolet-visible spectrophotometer.
