Design of an Intelligent Solar-LED Streetlight

Abstract:

Solar-led streetlight is a hotspot in photovoltaic lighting at present, it combines solar energy with HB LEDs (High Brightness Light Emitting Diodes) called the fourth generation of light source to improve the conventional streetlight in several aspects. Due to the clean nature of solar energy, and the highly efficient energy conversion of the PV module and very long operating life of the HB LED, the solar-LED streetlight, compared to traditional streetlight, can save electricity remarkably, thus abating greenhouse gas emission. During the photovoltaic lighting system, MPPT technology is generally used with the aim of maximizing the solar panel output power from beginning to the end. Therefore, if the controller combines MPPT technology with the traditionally constant-voltage charging technology, the charge efficiency will be greatly increased. While, for the discharge issue, people hope to modulate the brightness of streetlight so as to decrease the electricity consume.
