Abstract

This paper presents a color control algorithm for LED lights with independently changable illuminance. The proposed algorithm adjusts the light intensity to obtain a desired color with alterable illuminance To verify the validity of the proposed algorithm, it was applied to control of a RGBW LED module. The achieved color temperature range of the module was from 3000K to 7500K, and the illumination one was from 500 lux to 1500 lux.
