[Abstract]:Because of the advantages of energy saving, environmental protection and easy control, LED has been widely concerned and developed rapidly all over the world. It has become a new light source to change the pattern of global lighting industry. In this paper, an intelligent LED lighting system is designed by using power line carrier communication (PLC) dimming and computer control. This paper briefly analyzes the power line carrier communication technology and the PWM dimming technology, and presents the hardware composition of the intelligent LED lighting system, including the PLC coupling module, the PLC modem module, the LED dimming module, and the PLC transponder software. In the upper computer, the software of intelligent LED lighting system is designed in detail, including white light LED control, color LED control and color LED color scheme download, etc. The functions of controlling the brightness of white LED lamp and the color of color LED lamp by PLC bus are realized. Finally, the intelligent LED lighting system can realize the lighting control of two groups of white LED lamps, and the landscape lighting effect of one group of color LED lamps can meet the design requirements.
