Abstract
In this paper, we would like to propose and show the method for correcting deviated color temperature of LED lighting with White LED and RGB LEDs. LED may be shifted a coordinate of color temperature by the degradation of LED chips. We would like to correct from a shifted color temperature to an original color temperature as required. Through this study, it is produced LED downlight including white LED, RGB LED and color sensor. By applying the proposed algorithm, a lighting system is able to maintain a fixed color temperature. As a result, the human eye and emotion will feel more comfortable.
