Abstract

The invention relates to a gravity type flat heat pipe radiator for cooling an LED in the technical field of LEDs. The gravity type flat heat pipe radiator comprises a central radiating pipe, a combined radiating pipe, radiating fins, a cover plate and a straight rib, wherein the central radiating pipe is fixedly connected with the combined radiating pipe; the combined radiating pipe is fixedly connected with a substrate of the LED; the cover plate is fixedly arranged on the top of the combined radiating pipe; a plurality of radiating fins are fixedly arranged on upper and lower sides of the cover plate and are respectively connected with the externals of the central radiating pipe and the combined radiating pipe; and the straight rib is radially arranged in the combined radiating pipe and is connected with the radiating fins. The gravity type flat heat pipe radiator is a novel high-power LED radiator with the advantages of large radiating area, high radiating efficiency, good starting performance, light weight, good temperature uniformity, compact structure and convenient processing.

Description

technical field [0001] The invention relates to a device in the technical field of light-emitting diodes, in particular to a gravity-type flat heat pipe radiator for cooling LEDs with a power of more than 100W. Background technique [0002] LED has the advantages of energy saving, environmental protection, beauty, safety, long life, low power consumption, high brightness, short start-up time, waterproof, shockproof, easy dimming, concentrated beam, all solid state, easy maintenance, etc., as a new type of energy-saving lighting source It is being vigorously promoted. At present, the luminous efficiency of white light power LEDs has reached 167lm / W, and commercial products have also reached 100lm / W, which exceeds the average level of fluorescent lamps, and is much higher than the luminous efficiency of incandescent lamps and tungsten-halogen lamps. It is estimated that by 2020, the luminous efficiency of white LEDs will exceed all traditional light sources, and the theoretica...
