목표색온도 구현을 위한 서로 다른 색온도의 LED램프 조합비율 연구

Recently, the adjustable CCT(Con-elated Color Temperature) luminaire for the human circadian rhythm and room atmosphere has been developed. An accurate CCT control is needed in the luminaire for the human circadian rhythm Therefore, to make accurate ccr combination, the combination ratio for two different CCT lamps was calculated using three methods, and the most appropriate method was chosen. As a result, the third method considering change of tri-stimulus among the three methods was the most appropriate method to calculate the combination ratio.
