Heat dissipating structure of led lamp cup made of porous material

摘要

A heat dissipating structure of a lightweight lamp cup (10) made of a porous material includes a containing cavity (11) at an end of the lamp cup (10), a lamp holder (30) at another end of the containing cavity (11), a metal hood (60) sheathed with the lamp holder 30 and covered onto an external side of the lamp cup (10), a heat conduction medium (50) between the lamp cup (10) and the metal hood (60), and a light emitting unit (20) contained in the containing cavity (11) of the lamp cup (10), such that the heat produced by the light emitting unit (20) can be conducted form the lamp cup (10) to the metal hood (60) and dissipated from the metal hood (60) to the outside.
