Patent ID: 7828464

Claim:
An LED lamp structure with high-efficiency heat-dissipating function, comprising: a heat-dissipating module having a plurality of heat-dissipating fins, wherein the heat-dissipating fins are combined together to form a radial shape and a receiving space, wherein each heat-dissipating fin has an embedded portion and a finned portion extended forward, upward and downward from a lateral side of the embedded portion; a light-emitting module received in the receiving space of the heat-dissipating module; a power-transmitting module electrically connected with the light-emitting module; and a heat-dissipating substrate, the heat-dissipating substrate having a plurality of concave grooves formed on a peripheral face thereof in corresponding relationship with the embedded portions of said heat-dissipating fins, wherein each embedded portion of each heat-dissipating fin is embedded into a respective one of said plurality of concave grooves, and wherein the peripheral face of the heat-dissipating substrate abuts against inner lateral sides of the finned portions.
