Background technique

The street lamps currently installed on urban and rural roads have many forms and simple structures, but their functions are relatively single. Usually powered by alternating current. Its disadvantages are: the transmission line is long, it needs to consume a lot of electric energy, increase the cost of use, and it is difficult to maintain; there are also street lights that use solar panels for lighting. Its disadvantages are: it is greatly affected by weather changes, and after several consecutive cloudy days, the battery cannot be charged in time, the brightness of street lamps decreases due to voltage reduction, the lighting effect is not ideal, and even cannot work; there is also the use of wind energy light Complementary street lights can greatly improve the lighting effect, but because the wind generator of the wind energy generation system adopts propeller-type blades or wind direction rudder type, etc., it can only generate electricity when the starting wind speed and rated wind speed are relatively high. , it cannot play a role when the wind speed is small. At the same time, due to the high start-up wind speed of this kind of fan blade, it swings with the change of wind direction, the fan blade is vulnerable, the generator noise is large, the service life is low, the safety reliability is poor, the work performance is poor, the power generation utilization rate is low, and the Install at a position higher from the ground and farther away from the building. In addition to imperfect performance, the above-mentioned wind energy and light energy complementary street lamps also increase the production cost. Because some current wind energy and light energy complementary power generation circuit lights are not effective due to the problems existing in the wind power generation system.
