LEDs are widely used in illumination, indication and dimming area. Most commercial LED light dimming system today can achieve rough color temperature regulation with high but nonadjustable color rendering index. However most of these systems are designed for daily illumination, which cannot meet the precise requirement in the laboratory. In this work we achieved the design of color combination system with tunable luminance, color temperature, chromaticity coordinate and color rendering index with three to five color LEDs, which meets the experimental requirement to the greatest extent.
