Abstract：According to the need of stage art creation, this paper has proposed an improvement method for LED stage lights with light source choosing, design of heat radiator, design of light distribution, and dimming method of RGBW LED based on four channels’ PWM.Our experiment results showed that the light were well-distributed, and when dimming between 2300K to 3200K, the locus of color coordinate fits well with the black-body locus on the chromaticity diagram.
Keywords：LED stage lightsRGBW LED lightlighting performance improvementfitting the blackbody locus
