LED Lighting System Based on Solar Energy

This paper researches a lighting control system based on lighting emitting diodes (LEDs) as lighting source, solar energy as primary source and batteries as secondary source. Maximum power point tracker (MPPT) and the battery state (charged/discharged) are contained in this system. It presents a way to charge the batteries called uniform charging method and a new type high frequency impulse LED driving circuit. This system is based on digital signal processor TMS320F2812
