摘　　要：基于发光二极管(LED)在芯片级和系统级合成白光,暖色温的显色指数和光效较低,不能满足室内照明的要求,提出一种色温和亮度可调、高显色指数和较高光效的混光LED筒灯设计方法及控制策略。设计采用琥珀、白、蓝三色LED加色混光照明,根据三色LED的色度坐标、光通量比例,通过ZigBee无线控制三色LED电流值和混合比例,获得不同色温和亮度下的白光。通过搭建实验平台,实际测试显示,设计实现了色温和亮度可调,而且显色指数高。Based on light-emitting diode （LED） mixed of white light in chip level or system level, the color rendering index and luminous efficiency is low on warm color temperature, which cannot satisfy the requirement of indoor lighting.A mixed light LED down lamp design method and control strategy which can adjust the color temperature and luminance and with high color rendering index and luminous efficiency is presented.The LED down lamp used the amber, white and blue LED additive mix lighting, according to the chromaticity coordinates and luminous flux ratio of three color LED, used ZigBee wireless control current and mix proportion of three color LEDs, obtained white light under different color temperature and luminance.Through the construction of experimental platform,the actual test shows that the design achieved color temoerature and luminance adjustable, and high color rendering index.
