Abstract

The utility model relates to an LED street lamp, which comprises an electrical box, a radiating device and a head cover which are connected with each other. The radiating device is fixedly connected with an LED light source assembly. The radiating device comprises a plurality of radiating bodies. One surface of the radiating body is provided with a radiating flange, and the other surface is provided with a groove. The arrangement of the radiating flange on the radiating body increases the radiating area. The heating produced by the LED light source can be rapidly radiated with good radiation effect. The plurality of radiating bodies are respectively fixedly connected with LED light sources, which is favorable for the radiation of the heating. Sinxw sliding grooves are arranged on the radiating bodies, the radiating bodies on the two sides can rotate around the center line of a connecting hole, which can change the illumination angel of the LED light source arranged on the radiating body. The numerical value of the rotated angel can be read through the angle scale line arranged on the electrical box. The light source and the power supply are isolated during the using progress, and the heating of the two parts will not interfere with each other. Low voltage control increases the safety performance.
