Abstract: An LED lamp includes a lamp body having a heat sink forming an insert and a lamp holder which is connected to the heat sink of the lamp body. The lamp holder includes a mounting portion extending outwards from an external surface thereof. The mounting portion defines a socket. The insert is inserted into the socket to thereby connect the lamp body with the heat sink of the lamp holder. An light source module consisting of a plurality of LEDs is mounted on a bottom surface of the heat sink.

Abstract: An LED lamp assembly includes a first heat sink, a plurality of second heat sinks secured to a periphery of the first heat sink, a plurality of LED modules respectively attached to the second heat sinks and a plurality of heat pipes interconnecting the first heat sink and the second heat sinks. The first heat sink comprises a heat conducting body defining a through hole therein and a plurality of first fins around the heat conducting body. The second heat sinks each comprise a plurality of second fins facing the first fins of the first heat sink. The heat pipes each comprise an evaporating section attached to a corresponding second heat sink and a condensing section extending into the through hole of the heat conducting body of the first heat sink and attached to the heat conducting body.

Abstract: An LED lamp includes a lamp seat, a prism-shaped first heat sink disposed on a top of the lamp seat, a second heat sink covering a top of the first heat sink, a plurality of heat pipes thermally connecting the first heat sink with the second heat sink, a plurality of LED modules mounted on the first heat sink and an envelope located between the lamp seat and the second heat sink and surrounding the first heat sink. The first heat sink includes an annular base and a plurality of first fins and second fins extending therefrom. The LED modules are mounted on the first fins, respectively. Each heat pipe has two parallel sections respectively attached to a corresponding first fin and an inner circumferential periphery of the annular base.
