Patent ID: 7282841

Claim:
A lamp assembly with an LED light source, comprising: a heat sink body including a bundle of elongated heat conducting members having a first end face for mounting an infrared light emitting chip and a second end face for connecting a front face of a heat-conduction base, said first and second end faces being selected from one of planar surfaces and convex surfaces, said heat conducting members being confined by an insulating bracket locating close to said first end face, whereby said heat sink body can absorb the heat produced in said infrared light emitting chip and quickly transfer the heat to said heat-conduction base; the heat-conduction base having a first end and a second end; the first end being provided with a screw thread, said screw thread at said first end for engaging a screw thread formed on an inner wall of a lampshade, said heat-conduction base being capable of absorbing and dissipating the heat conducted from said heat sink body; the electrically insulating bracket for retaining and confining said heat conducting members of said heat sink body, said insulating bracket having an inner face attached on a front face of said heat-conduction base; and an infrared light base installed at a second end of the heat conducting base; an outer wall of the infrared light base being formed with a screw thread for engaging with the screw thread in an inner wall of the base shell, thereby securing the base shell and preventing damaging the screw thread wherein an outer side of the lampshade is a round cylinder with a unique diameter; the heat conduction base has a smooth cylinder after the screw thread thereof, diameters of the screw thread of the heat conduction base is smaller than that of the smooth cylinder; and an outer side of the smooth cylinder has an unique diameter; front face of the heat conduction base connecting the second end of the heat conducting member being a flat surface; the diameter of the smooth cylinder is smaller than an outer diameter of the lampshade; wherein wires that supply power to said LED light source are extended out from an end face of the heat conduction base; and wherein the electrically insulating bracket is formed by two rounds, an inner round and an outer round, the inner round is inside the outer round, a plurality of radiating ribs serves to connect the inner round to an outer rounds.
