Patent ID: 7549774

Claim:
A light emitting diode (LED) lamp, comprising: at least one LED unit; a thermally-conductive post being a column having an upper end and a lower end, wherein the upper end is provided with at least one through hole; a heat-dissipating module provided with a plurality of heat sinks, wherein each of the heat sinks has one end serially connected to each other and radially arranged on an outer periphery of the thermally-conductive post, and the other end apart from each other, so as to constitute the heat-dissipating module; and wherein the heat sinks are extended outward about a predetermined length in relation to the upper end of the thermally-conductive post, such that each of the heat sinks is formed with a step portion and all of the step portions are arranged coaxial to the thermally-conductive post and surrounding the upper end thereof; at least one base for mounting the LED unit thereon, wherein the base is mounted in the step portions formed on a central portion of the heat sinks of the heat-dissipating module; at least one cover member mounted in the step portions formed on the central portion of the heat sinks of the heat-dissipating module for covering the LED unit; a sheath for surrounding and positioning the heat sinks of the heat-dissipating module, so that the heat sinks are confined by the sheath; a foundation being a hollow housing provided with an opening on an upper end thereof, wherein the opening positions the heat sinks surrounding the lower end of the thermally-conductive post; and a printed circuit board (PCB) provided with a circuit, and mounted in the foundation, wherein the circuit of the PCB is electrically connected to the LED unit mounted on the base via the through hole of the thermally-conductive post.
