Patent ID: 7626213

Claim:
A light-emitting diode (LED) lamp, comprising: a columnar body being provided with a plurality of heat-radiating fins, a first through hole, a second through hole, an LED supporting end, and a mounting end; the heat-radiating fins being spaced along an outer circumferential surface of the columnar body to extend between the LED supporting end and the mounting end, and the first and the second through hole communicating the LED supporting end with the mounting end; a first conducting plate being disposed on a top of the LED supporting end and having a first conducting terminal received in the first through hole of the columnar body; an LED having a first electrode, a second electrode, and a light-emitting section; and the first electrode being electrically contacted with the first conducting plate; a second conducting plate being electrically contacted with the second electrode of the LED, and having a second conducting terminal received in the second through hole of the columnar body; a cap having a rear coupling end and a front end defining a central opening; the rear coupling end being covered around the LED supporting end of the columnar body, such that the first conducting plate, the second conducting plate, and the LED are located in the cap; and the light-emitting section of the LED being enclosed in the central opening at the front end of the cap; a first annular gasket being disposed between the LED supporting end of the columnar body and the rear coupling end of the cap; and a second annular gasket being disposed between the light-emitting section of the LED and the central opening of the cap.
