Abstract :
An intelligent dimming system based on LED lamps is presented. The design of hardware and software is given. The system has two working modes. One is manual mode and another is automatic mode. In manual mode, the brightness level of LED lamps is adjusted by keys. In automatic mode, the brightness level is adjusted automatically according to environment. An Infrared detector and a photo sensor are used to sample environment information. A STC-MCU is used to process the information and generate PWM control signals to set the lamps into predefined illumination modes. Compared to traditional control modes, the system features lower power consumption and is suitable for aisles and stair well.
