摘要(Abstract):

大功率LED在汽车前灯、夜间照明等领域有广泛应用,它的高效节能调光对于工业商业乃至生活都有重要意义。本文基于STM32单片机,采用PWM调光和蓝牙无线传输方式,实现无线大功率LED调光控制。PWM频率选择2 kHz,通过按键和蓝牙方式控制LED灯亮度,控制信息显示在LCD显示屏上。
High-power LED lamp has a wide range of applications in the automotive headlights, night lighting and other fields. It is of great significance to industry and commerce and even to life for its high-efficiency energy-saving dimming. Based on STM32 microcontroller, in this paper, PWM dimming and Bluetooth wireless transmission are used to accomplish wireless high-power LED lamps dimming control. 2 kHz is selected for PWM frequency, LED brightness can be controlled through buttons and Bluetooth, and the control information is displayed on the LCD screen.
