Design of Solar Energy Based Intelligent LED Street Lighting Controller
Abstract:
This paper aims to design an intelligent street lighting controller based on solar energy and LED. The controller can work in daytime mode, dusk mode based on detection of light intensity and photovoltaic voltage, and head into night mode after a certain period of time when in dusk mode. While in night mode, a dimming scheme is applied by introducing motion detection with passive infrared (PIR) sensors. The controller also integrates a ZigBee based WSN to report street lights status periodically and get instructions from the remote control center. Moreover, it can enable more efficient management and lower maintenance costs.
