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...
