Patent ID: RE44281

Claim:
A portable light comprising: a heat sink of a thermally conductive material comprising a first generally rectangular planar member, and a second generally rectangular member integrally joined to the first generally rectangular member; a light emitting diode attached to a broad surface of the first generally rectangular planar member of said heat sink; an electronic circuit board comprising circuitry for controlling the energizing of said light emitting diode, wherein said electronic circuit board is attached to the second generally rectangular planar member , the circuitry of said electronic circuit board including an electronic component that generates heat when energizing said light emitting diode and generates greater heat under a fault condition, wherein said electronic component is thermally coupled by said electronic circuit board to the second generally rectangular planar member of said heat sink to prevent the temperature of said electronic component from increasing excessively under the fault condition ; and a case for receiving said heat sink, said light emitting diode, said electronic circuit board, and a source of electrical power.
