Referring to FIG. 1 , the embodiment provides an LED street lamp, which is mainly used for illumination of LED light source at night, and provides illumination for passing vehicles, pedestrians, and monitoring devices.

The LED street lamp mainly comprises: a body, and an LED light source 1 mounted on the body, the LED street lamp further comprises: a water cooling channel 2 insulated from the LED light source 1 , and is connected to the water cooling channel 2 and has a rainwater inlet opening 31 Water storage tank 3.
