Abstract :
The combined lighting system consisting of LED street light system, power grid, photovoltaic (PV) arrays and driving circuits was investigated. To overcome the power shortage caused by several rainy days, the system is connected to the power grid. AC relay controls whether the battery or power grid lights LED according to battery voltage. Driving circuits are designed to stabilize and protect the working state of LED, in which the chip TNY275 and MAX16820 are selected for AC driving circuit and DC driving circuit, respectively.
