Abstract

For the purpose of energy saving and energy efficiency, the LED intelligent dimming system making use of solar power supply is designed in this paper. The system is based on STC12C5A60S2 microcontroller with multiple pyroelectric infrared detectors and light intensity sensors, in which LED dimming will be achieved according to the analysis and computation results through Multi-sensor data fusion technology. PWM dimming is adopted in the system depending on presetting programmable counter array (PCA) module of microcontroller in pulse width modulation (PWM) operation mode. Following the discussion about principle, composition and achievement, the Multi-sensor data fusion analysis is stated in accordance with different space distribution of light intensity sensors. Experiments show that the system is in simple structure and stable and reliable with the features of energy saving and intelligent.
