Condition of solar and wind energy resources is scenery complementary for the optimization design of the LED street light, is reflected in the allocation of resources is reasonable, the technical scheme is reasonable, the performance of the price is reasonable. Rationality that ensures the high reliability of LED scenery complementary street lamp. For example, in a local optimum design wind speed is 6 m/s, installing a nominal design wind speed is 8 m/s wind turbines, the results of its rated output power is only reached 42% of the original design output power, that is to say, the wind turbine rated output power than design value was reduced by 58%. Solar scenery complementary street lamp if choose of wind turbine rated design wind speed is higher, so the rated power output of the effect is more to be desired. Wind turbine rated design wind speed is low, the rotor diameter, motor relative to increase, the cost of the whole machine also increases accordingly, from the consideration on the manufacturing and product economic significance is not worthwhile. For scenery complementary LED lights use fan, compared to using small wind turbine start-up wind speed generally between 34 m/s, small wind turbine rated wind speed generally between 1215 m/s. Small wind turbines tend to maximum wind speed at about 25 m/s.
