An Energy Efficient LED Lighting System for Domestic Applications

This project is implemented on ARM, the sensor which detects the day light is used to switch outdoor lighting and the PIR sensor which detects the entering person into room are used here to regulate the indoor lighting intensity, which is done through PWM shifting technique. Saving the electricity is not difficult. Just by turn off the light when leaving the room, turn off computer when finish the work, unplug electronic accessories when finish recharging and etc. Various light regulate systems are introduced in prevailing markets, because the installed lighting systems are outdated and energy-inefficient. However, due to architectural constraints, the existing light regulate systems cannot be successfully applied to home and office buildings. Therefore, this paper proposes an intelligent domiciliary LED lighting system considering energy efficiency and user satisfaction. The proposed system employs multi sensors and wireless communication technology in order to regulate an LED light according to the user’s state and the surroundings. The proposed LED lighting system can individually adapt the minimum light intensity value to enhance both energy efficiency and user satisfaction. KeywordsDomiciliary LED lighting.
