The invention discloses a solar street lamp capable of being cleaned actively. The solar street lamp comprises a base, wherein the top end of the base is fixedly connected with the bottom end of a lamp pole, a stool is fixedly arranged on one side of the bottom of the lamp pole, and a guide
pipe is fixedly arranged on the side of the lamp pole; an
insect killing device is arranged on the side of the top of the guide
pipe, and the
insect killing device is composed of an
insect attracting box and a movable baffle; a lampshade is arranged at one end of the connecting
pipe; and a storage battery is fixedly arranged at the top end of the lampshade, a photovoltaic panel is fixedly arranged on one side of the storage battery, and a plurality of
LED lamp bodies are uniformly arranged inside the bottom end of the lampshade. According to the solar street lamp, by means of an arranged spray head, the surface, the
LED lamp bodies of the lampshade can be washed and cleaned conveniently, and accumulated dust and part of dead insects are flushed away; the photovoltaic panel is arranged so that
solar energy can be conveniently converted into
electric energy to be stored in the storage battery, andelectrical equipment such as an
LED lamp, an
ultraviolet lamp and the like can be used; and due to the fact that the insect killing device and an
ultraviolet lamp body are arranged, light
taxis, wavetaxis, color
taxis and other
taxis characters of insects can be conveniently used so that pests can be attracted to flap the
light source of the
ultraviolet lamp body, and can be killed by falling into the insect attracting box.
