Patent ID: 8282240

Claim:
An LED lamp comprising: a supporting base; a plurality of heat dissipation structures each comprising a bottom plate and a lateral plate extending upwardly and slantwise from the bottom plate, the bottom plates of the heat dissipation structures having inner ends adjacent to each other and close to a center of the supporting base and outer ends distant from the center of the supporting base in comparison with the inner ends, wherein the bottom plates of the heat dissipation structures are mounted on a top surface of the supporting base and surround a regular shaped zone on the top surface of supporting base, the lateral plates of the heat dissipation structures are separated from each other with a space defined between every two neighboring lateral plates and surround the regular shaped zone, the lateral plates of the heat dissipation structures each comprise an inner surface facing the regular shaped zone and an outer surface facing away from the regular shaped zone; an LED mounted on the outer surface of each of the lateral plates of the heat dissipation structures so that heat generated by the LED can be absorbed by each of the lateral plates; and a transparent envelope disposed on the top surface of the supporting base to cover the heat dissipation structures and the LEDs attached on the heat dissipation structures therein; wherein the lateral plates of the heat dissipation structures are extended from the outer ends of the bottom plates, respectively and slantwise toward each other along a bottom-to-top direction of the LED lamp; wherein the heat dissipation structures each are a unitary structure.
