Abstract:
1. A light emitting diode (LED) light bulb, comprising a light shade, a heat conduction base, a plurality of heat sink fins, a heat conduction member and a plurality of LED light emitting elements, wherein the light shade is coupled to the plurality of heat sink fins; the heat conduction base, the heat conduction member and the plurality of LED light emitting elements are disposed between the light shade and the plurality of heat sink fins; the heat conduction base has one end connected with the heat conduction member, a circumferential portion connected with the plurality of heat sink fins and a central hole to accommodate the heat conduction member; the plurality of heat sink fins are coupled to the circumferential portion of the heat conduction base; the heat conduction member is coupled in the central hole of the heat conduction base and has an exposed end formed with a plurality of inclined planes and a top plane by stamping, each of the inclined planes and the top plane being coupled with at least one of the LED light emitting elements, respectively; and each of the LED light emitting elements is composed of a single light emitting chip or a plurality of light emitting chips; whereby, with the inclined planes and the top plane at different angles, the plurality of LED light emitting elements project light in multiple directions, and the heat from the LED light emitting elements is transmitted to the plurality of heat sink fins through the heat conduction member to be dissipated quickly.
