Patent ID: 7081645

Claim:
An SMD-type light emitting diode with high efficiency of heat dissipation, comprising: a base including a post arranged and integrated at the center thereof, a slot formed on the top of the post; wherein at least one contact hole is disposed at the bottom of the base; at least one LED chip mounted in the slot of the base; and a circuitry extension device having a central hole, at least a first pair of positive and negative contacts, and at least a second pair of positive and negative contacts for connecting to an external circuit; the first pair of positive and negative contacts being positioned over an upper surface of the circuitry extension device for connecting with the positive and negative electrodes, respectively, of the LED chip; the circuitry extension device being disposed on the top of the base and being connected with the base by a heat resistant glue, wherein said post of said base extends through said central hole of said circuitry extension device; wherein the LED chip is electrically connected with the circuitry extension device by a wire selected from a group consisting of a gold wire and an aluminum wire, and further connected with the external circuit through an extension circuit on the upper surface of the circuitry extension device.
