Abstract :
A LED control system is presented. The brightness and color temperature of the lamp are adjustable. The system composition and design of hardware and software are given. The infrared signal is sent by an infrared remote controller. A STC-MCU is used to process the infrared information and generate PWM signals which can adjust the brightness of the white LED and yellow LED respectively. It proves that the system is convenient, reliable and practical, and suitable for indoor illumination.
