Abstract

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.

设计具有特定目标参数控制功能的LED调光系统
led广泛应用于照明、指示和调光领域。目前大多数商用LED调光系统可以实现粗略的色温调节,显色指数高但不可调。然而,这些系统大多是为日常照明设计的,无法满足实验室的精确要求。在本工作中,我们用三到五色led实现了亮度、色温、色度坐标和显色指数可调的组合色系统设计,最大程度地满足了实验要求。
