摘要

为了提供高品质、更安全和智能的照明光源，基于冷暖白光LED建立了线性调光混合照明系统及其优化调光调色方法。混合照明光源以色温和明度等级分别设定光色度和光强度，更加符合人性化需求。在系统智能优化配光过程中，设定色温转换为CIE

u'v'

均匀色品坐标，明度转换为亮度，使优化计算更加精确。系统采用的线性调光避免了闪烁潜在的安全风险，同时配合优化算法解决了线性调光色度漂移大的问题。实验结果表明，系统混合光的色度稳定性可以保持在1阶CIE

u'v'

圆内，相应色度设定下的整个光强度调节范围内无可察觉的色差。理论研究和实验结果表明该混光照明系统简单可行，具有较高的实用价值。

Abstract

To provide high quality

more safe and intelligent lighting source

the linear dimming mixed lighting system and its dimming and color modulation method were established based on the cold and warm white LEDs. The mixed lighting source set the light color and intensity using color temperature and lightness

which was more accord with humanized requirements. In the procedure of system intelligent light distribution optimization

the color temperature was converted to chromaticity coordinate on the CIE

u'v'

diagram and the lightness was converted to luminance

which made the optimizing computation more precise. The system adopted linear dimming method to avoid safety risk induced by flicker

and the adopted optimization algorithm solved the big color shift problem of linear dimming. The experiment results show that the chromaticity stability of the mixed lighting system can keep within 1-step CIE

u'v'

circle

which means with specific chromaticity setting

there is no perceivable chromatic aberration. The theoretical research and experiment results show that the mixed lighting system is simple

practicable and with high practical value.
