Abstract

The invention discloses an annular steam cavity radiating module for a high-power LED lamp. The module comprises a print circuit board (PCB) board and an annular steam cavity, wherein the PCB board is provided with a plurality of high-power LED lamps; the annular steam cavity is enclosed by an outer shell with fins, a hollow cylinder and sealing plates at the upper end and the lower end of the annular steam cavity; the distance between the inner surface of the outer shell and the outer surface of the hollow cylinder is at least 10mm; V-shaped channels are formed on the inner surface of the outer shell and the outer surface of the hollow cylinder; the radiating fins are arranged on the outer shell at the condensing end of the annular steam cavity; the hollow part of the hollow cylinder is used for leading out the power line of the PCB board; and liquid working medium is filled in the annular steam cavity. The module can effectively solve the problem of the radiation of the high-power LED under the condition of no extra dynamic, improves the service life of the LED lamp, and has a simple structure and low cost.

Description

technical field [0001] The invention relates to a heat dissipation device, in particular to an annular steam chamber heat dissipation module with high efficiency, simple structure and high-power LED lamp. technical background [0002] LED semiconductor lighting is the fourth-generation electric light source after incandescent lamps, fluorescent lamps and rare gas lamps. Because of its advantages of high efficiency, long life, energy saving and environmental protection, it has become the source of light source and lamp research institutions all over the world. The goal is to be a star industry in the lighting field in the future. With the continuous progress of LED manufacturing technology and the development and application of new materials (nitride crystals and phosphors), the performance of white-emitting LED semiconductor solid-state light sources has been continuously improved and entered into a practical stage. Special light sources such as lamps are gradually moving i...
