摘要
根据混色原理,证明了利用红光、正白光和蓝光三种颜色的LED混合实现色温调节的可行性。把色温可调白光LED照明系统分为五个模块,对五个模块进行设计和优化,实现了显色指数高、色温动态可调、光谱覆盖范围广、能适应不同时间、场所对色温可变要求的LED照明系统。
According to color mixing principle, adjustable color temperature is proved to be feasible by using nomal white, red and blue LED. The white LED lighting system is divided into five modules, and then each module is designed and optimized. Finally, an upgraded LED light- ing system is realized, which has high CRI, dynamic adjustable color temperature, wide spectral range to meet the requirements of adjustable color temperature for different time and different places.
