독립적으로 조도변경 가능한 LED 조명 색상제어 알고리즘

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.
