| 摘 要： | 根据光电信息科学与工程专业光电综合实验课程教学的需要,研制了基于红外遥控的三基色LED调光调色实验教学系统,该系统使用红外遥控器作为控制器,以PIC单片机作为控制芯片,通过红外一体化接收器对红外发射信号进行接收并将解调好的信号送给单片机,单片机将该信号解码并执行相应程序控制对应的LED阵列电路,并通过PWM模块驱动LED亮灭,通过调整占空比输出控制电路的通断时间,高速闪烁的LED在调控不同的占空比下呈现不同的亮度及颜色。利用该实验教学系统可以帮助学生了解并掌握利用PWM技术实现三基色LED的调光方法。

| Abstract: | According to the need of teaching of the photoelectric comprehensive experiment courses for Photoelectric Information Science and Engineering specialty,the experimental teaching system of tri-primary color LED dimming and color matching based on infrared remote control is developed.This system uses the infrared remote controller as controller and PIC MCU as control chip,which receives the infrared emission signal through infrared integrated receiver and sends demodulated signal to a MCU.The MCU decodes the signal and executes the corresponding program to control the corresponding LED array circuit,and drives the LED to turn off through the PWM module.By adjusting the on-off time of the duty cycle output control circuit,the high-speed flickering LED shows different brightness and color under different duty cycles.Using this experimental teaching system can help students to understand and master the dimming method of tri-primary color LED by the PWM technology. |
