Abstract

See full text

A method for adjusting color rendering index of a light source and a stage light fixture are provided. The light source has a first LED chip set with a first color rendering index and a second LED chip set with a second color rendering index. The range of chromaticity differences of a target spectrum and color differences of 14 Munsell color samples of the target spectrum are defined according to a target spectral power distribution of a reference light source under a target color rending index and a target color temperature. The light intensity control parameter K1, K2 of the first LED chip set and the second LED chip set are adjusted, and a relative spectral power distribution of synthesized lighting of the controlled light source is calculated to search for values of K1 and K2 enabling the relative spectral power distribution to fall within the range.
