LED (light-emitting diode) street lamp

Abstract

The invention discloses an LED (light-emitting diode) street lamp, which comprises a lampshade, a radiator and at least one LED lamp bank, wherein the radiator is of a blocky structure; cooling fins are distributed on the side face of the radiator; a cooling flow channel penetrates each of the left side and the right side of the radiator; each LED lamp bank is evenly distributed on the lower surface of the radiator; the radiator is fixedly arranged in the lampshade. The LED street lamp disclosed by the invention is simple in structure and easy to process and can be conveniently combined with the traditional street lamp pole; by arranging the cooling fins and the cooling flow channels, the cooling effect is enhanced, and the problems that the radiator is locally overheated and cooling is not even are effectively solved; the LED lamp banks are distributed on the upper surface or the lower surface of the radiator, so that heat is further dispersed; the heat dissipation area of the radiator is fully utilized; meanwhile, light rays of the whole LED street lamp are evener, and the illuminating effect is promoted.

Description

technical field [0001] The invention belongs to the field of lighting equipment, and in particular relates to an LED street lamp. Background technique [0002] As an energy-saving, environmentally friendly, green and healthy light source equipment, LED lights are widely promoted and applied, but LED lights generate high heat, especially in high-power applications. The heat dissipation problem directly affects the service life of LED light source equipment and limits the LED light source. promotional application. Applying LED light sources to street lighting, it is difficult to use fans to force heat dissipation, high cost, and difficult to maintain. Therefore, the design of the radiator will directly affect the service life and lighting effect of LED lights. In the existing street lighting equipment that uses LEDs as light sources, The heat sink used is complex in structure, inconvenient to install, high in processing technology requirements, and expensive in production cos...

Applying LED light sources to street lighting, it is difficult to use fans to force heat dissipation, high cost, and difficult to maintain. Therefore, the design of the radiator will directly affect the service life and lighting effect of LED lights. In the existing street lighting equipment that uses LEDs as light sources, The heat sink used is complex in structure, inconvenient to install, high in processing technology requirements, and expensive in production costs. At the same time, in conventional high-power LED street lights, the LED light source generates heat intensively and emits uneven light, which affects the use effect and life of LED street lights.
