LED lamp with concurrent flow vapor chamber radiator

Abstract

The invention discloses an LED lamp with a concurrent flow vapor chamber radiator. The LED lamp with the concurrent flow vapor chamber radiator includes an LED light source and the concurrent flow vapor chamber radiator. The concurrent flow vapor chamber radiator includes a concurrent flow vapor chamber, and the concurrent flow vapor chamber includes a flat tube and at least one heat conducting piece. The flat tube is a flat sealing tube with two planes on the upper and lower face and a gap in the middle. The heat conducting piece is arranged in the flat tube and connected with the upper and lower wall of the flat tube, and penetrates through the both ends of the flat tube. The flat tube is divided into a plurality of cavities by the heat conducting piece. Liquid heat conducting working medium is filled into the cavities. The LED light source is arranged on the upper surface of the concurrent flow vapor chamber. The concurrent flow vapor chamber radiator further includes heat conducting fins, and the heat conducting fins are fixed on the outer side of the upward bending position of the concurrent flow vapor chamber. The LED lamp with the concurrent flow vapor chamber radiator has good heat dissipation performance, and is conducive to the miniaturization and lightweight design of the LED lamp of single power source.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED lamp with a parallel-flow uniform temperature plate radiator. Background technique [0002] Engineering applications such as architectural landscape stereoscopic lighting, stage lighting and long-distance lighting require the use of upward lighting lamps. Traditional lamps use metal halide lamps or high-pressure sodium lamps as light sources, both of which need to use ballasts, resulting in high energy consumption for the entire lamp, large lamp size, low luminous flux utilization rate, and serious light decay. With the development of semiconductor lighting technology, LED lamps are widely used in the above-mentioned engineering lighting. At present, most LED lamps adopt the form of multiple LED lamp beads evenly distributed on the light source surface, and each lamp bead has its own light distribution, but this form is only suitable for low power, generally ranging from 1W to 30W. As the ...
