Patent ID: 7837358

Claim:
A light-emitting diode module comprising: a metal substrate having a first face and a second face opposite to the first face; a plurality of light-emitting diode dies mounted to the first face of the metal substrate and in direct, thermal contact with the metal substrate; a jacket including a coupling surface engaged with the second face of the metal substrate, with the jacket further including a longitudinal hole having a longitudinal axis, with the coupling surface of the jacket having an opening extending in a direction parallel to the longitudinal axis and in communication with the longitudinal hole; a heat conduction pipe including a first portion received in the longitudinal hole of the jacket and a second portion outside the jacket, with the first portion of the heat conduction pipe having an outer periphery, with a portion of the outer periphery of the first portion of the heat conduction pipe being in direct, thermal contact with the second face of the metal substrate through the opening of the jacket to absorb heat generated by the plurality of light-emitting diode dies; and a finned heat sink mounted on the second portion of the heat conduction pipe and including a plurality of fins to dissipate heat transferred to the heat conduction pipe into an environment outside the finned heat sink.
