MacAdam ellipses step에 따른 백색광 범위 분석

For analysis on range of white light according to MacAdam ellipses steps, this paper reviewed a geometrical construction and parameters of MacAdam ellipses, and investigated color coordinate range(x, y) of MacAdam ellipses in ANSI-NEMA. As a result, the size of MacAdam ellipses was decreased accordance with steps at regular intervals. Also, it was wide in the order of 4100K, 3500K, 5000K, 3000K, 2700K, and 6500K.
