Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] like figure 1 , an LED street lamp provided in this specific embodiment includes a heat pipe 1 , a heat dissipation rib 2 and a lamp body. The heat dissipation ribs 2 are independently arranged outside the lamp body, such as the rear part of the lamp body, etc., and its setting position can be adjusted according to the actual situation. One end of the heat pipe 1 extends into the lamp body and is connected with the light source inside the lampshade, which can speed up the heating process. The conduction speed of the heat generated by the power LED from the inside of the lampshade to the outside, runs through the heat dissipation ribs 2 outside the lampshade, and is used to transfer the heat generated by the light source components to the heat dissipation ribs 2 .

[0031] The heat pipe 1 is sealed with a sealing ring 9 at the junction w...

Abstract

The invention discloses an LED streetlamp, which comprises a heat conducting tube, a radiating rib plate and a lamp body. The radiating rib plate is arranged outside the lamp body, one end of the heat conducting tube extends into the lamp body and is connected with an LED light source inside the lamp body, the other end of the heat conducting tube penetrates through the radiating rib plate, and heat generated from the LED light source is transmitted to the radiating rib plate through the heat conducting tube. The lamp body comprises an upper lampshade, a lower lampshade, a reflector plate, a base plate and a circuit driving system, wherein the upper lampshade and the lower lampshade are combined to form a lampshade in a fastening manner, the reflector plate, the base plate, the LED light source and the circuit driving system are all arranged in the lampshade, the edge of the reflector plate is fastened to the joint between the upper lampshade and the lower lampshade, the lampshade is divided into two parts, the heat conducting tube is embedded on one side of the base plate, the LED light source is embedded on the other side of the base plate, the whole base plate is attached on the reflector plate I, and the circuit driving system is arranged at the tail of the lamp body. The LED streetlamp has the advantages that problems about heat radiating and light distributing of the LED streetlamp of the prior art are solved well.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a street lamp with simple structure, easy assembly and excellent heat dissipation performance. technical background [0002] High-power LED street lamp is a street lamp with a single power greater than 30 watts and a new type of LED semiconductor light source. It has a very good application prospect in the lighting of emerging cities. [0003] Heat dissipation and reliability are the main factors affecting the application of high-power LEDs. With the continuous improvement of the output power of LED chips, higher requirements are put forward for the heat dissipation technology of high-power LED lamps. The heat dissipation of LED packaged light sources has always been a very important problem encountered in the development of LED products, among which the thermal conductivity of product materials is very critical. At present, the heat dissipation system of high-power white LEDs...
