But the wind hybrid power LED street lamp is based on wind and solar power generation systems, new energy efficient skills of green lighting products. It is posed of solar panels, wind generator, controller, batteries, drives, highpower LED and other selfsufficient green lighting system. Wind and solar power LED street lamp it is a system controller, wind turbines, solar panels module wind and solar energy into electrical energy transformed into electrical energy and stored in the governance battery after the drive powerdriven highpower LED lights work properly . But we need to understand that all LED including street lighting, high power LED is driven by the DC voltage, and highpower LED is a special nonlinear electrical, optical and thermal characteristics, to ensure its stability , you must also have constant current for normal work. The AC power used by the general household appliances and street lights can not be directly used to drive high power LED. The DC power supply, power supply must be reinvented to ensure stable current output in order to apply for driving highpower LED. This paper first analyzes the wind hybrid street light development prospects and the development environment, a detailed analysis of the characteristics of high power LED. And in accordance with the requirements of highpower LED lights, and ensure the normal work of the highpower LED indicators, with reference to the more mon and less expensive drive power circuit analysis and improvement, and plete sets of feasible power LED street lamp driver available circuit, two sets of circuits plement each other to solve the wind, and hybrid power LED street lamp drive power requirements of the DC / DC voltage, constant current output, the efficiency of the work efficiency, power factor, overheating protection design elements.
