Abstract:
1. A portable light including thermal protection comprising: a cup-shaped thermally-conductive heat sink having a wall and a closed end defining a central cavity, the closed end having first and second opposing surfaces; a light-emitting diode having a surface adapted for conducting heat to a heat sink, wherein the surface of said light emitting diode abuts and is in thermal contact with the first surface of the closed end of said heat sink; an electronic circuit for controlling a voltage, a current, or a voltage and a current, applied to said light-emitting diode, wherein said electronic circuit is adjacent the second surface of the closed end of said heat sink; and a thermally-conductive material filling between said electronic circuit and the second surface of said heat sink for providing a thermally conductive path therebetween, whereby said light-emitting diode and said electronic circuit are thermally coupled to said heat sink.
