Abstract

A LED intelligent wireless dimming system based on AVR microcontroller is designed in this paper. The system is part of a highly integrated drive power flyback power supply topologies, Using MAX16802 as a constant current LED driver, dimming part is ATmeage16 precise timing control microcontroller as the core, the use of AVR microcontroller timer to generate variable duty cycle PWM signal for the LED lights dimming. Infrared remote control is used as wireless control module with the advantages of small size, low cost, low power consumption and etc, the experimental results show the high efficiency LED dimming systems designed to meet voltage and current requirements of high-power LED lighting work, with good wireless dimming function.
