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 present 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 above 100W. Background technique [0002] LED has the advantages of energy saving, environmental protection, beauty, safety, long life, low consumption, high brightness, short startup 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 LED has reached 167lm / W, and the product has reached 100lm / W, exceeding the average level of fluorescent lamps, and much higher than the luminous efficiency of incandescent lamps and halogen lamps. It is estimated that by 2020, the luminous efficiency of white LEDs will exceed all traditional light sources, and the theoretical efficiency can reach 300lm / W. With the three major d...
