Example Embodiment

[0017] like Figure 1-4 The shown LED street lamp includes a lamp pole 1 , a lamp body 2 fixed on the lamp pole 1 and an LED light source arranged in the lamp body 2 .

[0018] The lamp body 2 includes an upper cover 3 and a transparent lower cover 4 arranged at the bottom of the upper cover 3 , the upper cover 3 is fixed on the light pole 1 , and the upper cover 3 and the transparent lower cover 4 are fixed by screws. The top of the upper cover 3 is provided with several frustum-shaped protrusions 30 . The top of the protrusion 30 is platform-shaped, which is used for connecting with the LED module 6 . The protrusion 30 is arranged in a frustum shape to prevent rainwater from accumulating. To facilitate connection with the LED module 6 , a screw hole 34 penetrating through the upper cover 3 is provided on the top of each protrusion 30 . In order to prevent rainwater from seeping into the screw hole 34 , the top of each protrusion 30 is provided with an annular convex strip...

Abstract

The invention discloses an efficiently-cooled LED street lamp which comprises a lamp post, a lamp body and an LED light source. The lamp body comprises an upper cover and a transparent lower cover. The upper cover is fixed to the lamp post. The top of the upper cover is provided with a plurality of frustum-shaped protrusions. The top of each protrusion is provided with a screw hole and an annular protruding strip. The LED light source is composed of a plurality of independent LED modules. Each LED module comprises a cooler and an LED light emitting assembly fixedly arranged at the bottom of the cooler. Each cooler comprises a body and cooling fins arranged on the top of the body, wherein 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, the radial edge of the boss is provided with a thread matched with the screw hole, the corresponding light emitting assembly is arranged at the bottom of the boss, and the annular groove surrounds the radial edge of the boss and is matched with the corresponding annular protruding strip. The LED street lamp is good in universality and replaceability, low in maintenance cost and good in cooling 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...
