Abstract
The invention discloses a heat dissipation bracket, a manufacturing method of the heat dissipation bracket and an LED (Light-Emitting diode) using the heat dissipation bracket. A nanometer ceramic layer is arranged on the surface of a bracket main body of the heat dissipation bracket; heat energy generated by light-emitting members such as the LED lamp is transferred to the nanometer ceramic layer through the bracket main body; the nanometer ceramic layer in a temperature rise process excites Far infrared; and the Far infrared carries thermal molecules to subject to efficient exchange with a normal environment temperature in a form of heat radiation. The heat radiation of the nanometer ceramic layer becomes stronger along with the increase of the temperature of the heat dissipation bracket, so that accumulated heat energy generated in the operation of the lamp (such as the LED lamp) is guaranteed to be released efficiently, the heat dissipation efficiency of the LED lamp is further improved, the service life is prolonged, and the light-emitting efficiency is kept efficiently. The heat dissipation bracket, disclosed by the invention, has the advantage of small and exquisite volume of the heat dissipation bracket; and compared with a lamp which dissipates heat by utilizing a fan, the lamp structure adopting the heat dissipation bracket is more compact and smaller in volume.
