Self-cooling type LED street lamp

Abstract

The invention discloses a self-cooling type LED street lamp. The self-cooling type LED street lamp comprises a lamp pole and blades. Transverse disc-shaped fixing plates are welded on the inner wall of the lamp pole, the lamp pole and a lampshade are welded into a whole, and a base is welded at the bottom end of the lamp pole. A cable pipe and a water pipe are inserted into the lamp pole, penetrate through the transverse fixing plates and are connected with the transverse fixing plates in an adhesion mode. A cable is inserted into the cable pipe, the cable and the water pipe are connected witha power supply network and a water supply network correspondingly, and the cable extends into the lampshade and is electrically connected with a pedestal. Cooling fins are welded on the surface of the top end of the lampshade. Ammonium nitrate powder is arranged inside the self-cooling type LED street lamp, a large amount of heat is absorbed after the ammonium nitrate powder touches water, the blades are arranged, the airflow which rapidly flows can take away the heat on the wall body of the lampshade, and is matched with the ammonium nitrate powder to achieve double heat dissipation, and therefore the LED street lamp can have a self-cooling function, is free of energy consumption and is good in heat dissipation effect.

Description

technical field [0001] The invention relates to the technical field of LED street lamps, in particular to a self-cooling LED street lamp. Background technique [0002] When the existing LED street lamps work for a long time, the LED light source will generate a lot of heat, so that the heat will be dissipated into the air through heat exchange. This method has a slow cooling effect. At present, there is a street lamp on the market. A fan is installed to dissipate heat inside it, but the fan needs to consume electric energy when it rotates, which increases energy consumption, is not practical, and cannot meet people's use needs. In view of the defects in the above prior art, it is necessary to use it Further improvement to make it more practical can meet the actual use conditions. Contents of the invention [0003] The purpose of the present invention is to provide a self-cooling LED street lamp, so as to solve the problem of poor heat dissipation of the existing street la...
