NOVELTY - The utility model claims a high-efficient heat phase-change LED lamp heat conducting column and its radiating structure, heat conducting column, comprising a water absorbing layer, the absorbing layer is coated with a carbon fibre layer, the carbon fibre layer is covered by a graphene layer. a radiating structure, comprising a radiating cavity, the radiating cavity is filled with phase transition liquid, the radiating cavity is provided with a heat conducting column, the heat conducting post contacting with the phase change liquid. is phase transition liquid absorbs water absorbing layer, under the action of capillary force, it can rotate at any angle can ensure the absorbing layer can be absorbed into the absorbent layer. after the water absorption layer is coated with a layer of carbon fibre, the carbon fibre has good water absorption, but also has good thermal conductivity, capable of absorbing while conducting heat to the absorbing layer in the phase change liquid volatilizes, so as to transfer the heat radiating effect.
