LED, as a kind of device can convert electric power into visible light directly the homomorphism of semiconductor devices, with high efficiency and small energy consumption, good light quality, use safety, long service life, green environmental protection, flexible control as this is common lamps and lanterns is incomparable advantage. Therefore, it is considered to be 21 century of a new generation of lighting source. Based on the superiority of LED, it is widely applied in many fields of lighting. To enhance the traditional solar based pure LED system, we enhance it with the combination of the wind power and the optimized controller that holds specific meaning.展开更多
