Abstract：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 .
