Abstract

The invention is applied to the technical field of illumination, and provides a light source color rendering performance spectrum diagnosis method and system. The method comprises the following steps: calculating a color rendering index of light source spectrum energy distribution; extracting a monochromatic spectrum in the light source spectrum energy distribution, adding equal-energy white light, and drawing a spectral purity curve on a chromaticity diagram so as to form a spectrum color domain area; calculating a spectrum color domain area index, and evaluating a deletion condition of the spectrum; determining a deletion position needing to be added to the spectrum through combination with the spectrum color domain area and the deletion condition of the spectrum; according to a spectrum main wavelength and a peak value wavelength, determining a needed peak value wavelength spectrum; and determining a proportion needing to be added to a deletion portion spectrum, obtaining a generation light source spectrum and calculating a color rendering index so as to realize diagnosis of the spectrum. According to the invention, physical quantity based spectrum energy distribution is converted into a vision-based spectrum color domain area, visual determination can be carried out, the color rendering performance can be improved, and a spectrum problem can be accurately diagnosed.

Description

technical field [0001] The invention relates to the field of lighting technology, in particular to the field of chromaticity, in particular to a spectral diagnosis method and system for the color rendering property of a light source. Background technique [0002] Light source color rendering is a very important parameter used to represent the authenticity of the light source to the object. Traditional light sources are represented by the color rendering index CRI (ColorRenderingIndex). For traditional light sources, this method is better. However, with the emergence of new light source LEDs, more and more problems have appeared in the color rendering index CRI. The CIE technical report pointed out that the results obtained by CRI for the color rendering evaluation of a series of light sources including LED light sources are not satisfactory. In order to correctly evaluate the color rendering of LED light sources, it is necessary to conduct in-depth discussion and research ...
