Compared with the traditional lighting, intelligent lighting systems which use light emitting diode (LED) as the light source are efficient, comfortable and environmentally friendly. Real-time acquisition and dynamic feedback for environmental data are the research focus for LED intelligent lighting systems. Based on the modular design mentality, an integrated LED intelligent lighting system is proposed, and the mapping relationship among environmental parameters, human comfort index and output parameters of light source is established. The multi-channel integrated module is used to monitor the change of environmental parameters in real time, and the optical properties of the light source can be adjusted automatically to satisfy the requirement of human comfort. The established system can synchronously collect and feed back the sound, temperature, humidity and illumination in the space environment. By analyzing the changes of luminous flux, color temperature, spectrum and color rendering index in real time, we demonstrate the validity of the established system. The proposed system achieves the synergy fusion of automatic control and green lighting, and it is a kind of generalized, low-cost and humanized lighting control system. The system will has a broad application prospect in the field of lighting and display.
