Description

The present invention takes up the field of lighting technology, and particularly relates to a street lamp having a defrosting function and capable of self-cleaning when the brightness is insufficient.

A street light is a device that provides lighting to a driving vehicle or a passerby, and if it is not cleaned for a long time, the brightness will decrease, but it is inconvenient to remove dirt because there are many street lights and the position of the lamp is high. is there. Currently, the cleaning of street lights is basically done by workers on a lift, but while there are safety issues, it is also inefficient. Also, manual work can only deal with the outer surface of the light bulb. The water fog generated inside the light bulb also affects the lighting effect. If the contents cannot be dealt with, the light bulb with water fog can only be replaced, resulting in waste.
