Design of a New Solar LED Lamp Controller Based on ZigBee
Abstract: There are some problems in photovoltaic lighting systems, such as low efficiency, instabilities, short battery life, etc. To solve these problems, a novel type of ZigBee solar street lamp controller with wireless networking function is designed in this paper. The controller consists of five main parts: charging circuit, sensor module, LED driving circuit, wireless communication module and power management module. The real-time working state of battery is monitored and switched accurately to improve the efficiency of charging. Perturbation and Observation Method is used to realize maximum power point tracking (MPPT) of the solar panel. A constant-current control is taken to achieve energy-saving. The networking strategy combined ZigBee, GPRS, Internet is applied, so the solar lamps can establish network by themselves and be monitored and controlled by remote center. By testing the experimental result, it is proven that the solar LED lamps with this new controller can operate efficiently, stably, and be managed intelligently. It has a broad application prospect.
