摘　　要：利用多种单色LED的混光,通过自主研发的Zigbee控制系统在室内实现光谱色温可调照明系统。基于单色LED的实测参数,借助迭代程序的计算结果,通过Zigbee智能控制给各单色LED施加相应的电流,最终实现光通量和显色性可控、色温可调（2700~6400K）的室内照明。开展了基于光通量最高或显色指数最高为目标的光谱匹配算法研究及系统实现,实测结果表明工作面照度均大于200lx,照度均匀度大于0.85,色温均匀度大于0.9,满足科学实验和室内办公的需求。The article mixes the light of several monochrome LEDs and uses Zigbee control system to achieve spectrally tunable indoor lighting system .Based on the measured parameters of monochrome LEDs and the computing results of iterative algorithm , all monochrome LEDs are applied corresponding current by means of Zigbee.Finally, the indoor lighting is achieved, in which the flux or CRI is controllable and the CCT （2700 ~6400K） is tunable.The spectral matching algorithm and the spectrally tunable LED lighting system are achieved based on the maximum flux or CRI .The test result shows that the illuminance on the working surface is above 200 lx and the uniformity of illuminance and CCT is above 0.85 and 0.9 respectively, which meets the needs of the scientific research or work indoors .
