A LED street light with high efficiency heat dissipation

Abstract

The invention discloses a high-efficiency heat-dissipating LED street lamp, which comprises a lamp post, a lamp body and an LED light source; the lamp body includes an upper cover and a transparent lower cover, the upper cover is fixed on the lamp post, and several cones are arranged on the top of the upper cover Shaped protrusions, wherein, the top of each protrusion is provided with a screw hole and an annular raised strip; the LED light source is composed of several independent LED modules, wherein each LED module includes a heat sink and a heat sink fixed at the bottom of the heat sink LED light-emitting assembly; the radiator includes a body and heat dissipation fins arranged on the top of the body, the bottom of the body is provided with a cylindrical boss and an annular groove, the boss is arranged at the center of the bottom of the body, and the radial edge of the boss is provided with The screw thread matched with the screw hole, the light-emitting component is arranged on the bottom of the boss, and the annular groove is arranged around the radial edge of the boss and matched with the annular convex strip. The LED street lamp of the invention has good versatility and replaceability, low maintenance cost and good heat dissipation effect.

Description

technical field [0001] The invention relates to an efficient heat dissipation LED street lamp, in particular to a modular LED street lamp. Background technique [0002] The design of LED street lamps in the prior art is usually designed to imitate the design of traditional street lamps, and multiple LED lamp beads are assembled in a module, so that the products produced by different manufacturers do not have universality and interchangeability, resulting in LED street lamps. Poor replacement and high maintenance costs indirectly increase the cost of using street lights. In addition, because LED street lights need to withstand wind and rain, for this reason, LED street lights in the prior art usually completely seal the LED street lights to prevent water leakage, making it very difficult to dissipate heat from the LED street lights, resulting in the heat dissipation effect of the LED street lights not ideal. Contents of the invention [0003] The present invention aims to...
