Patent ID: 7314290

Claim:
A high intensity discharge lamp assembly for providing illumination within an environment surrounding the lamp, comprising: a high intensity discharge lamp comprising a hermetically sealed glass envelope containing a mixture of ionizable elements and/or compounds and a mounting base on said envelope; a pair of high voltage conductors extending from said glass envelope and through said mounting base; an electronic ballast having a pair of low DC voltage input connectors and a pair of high voltage output connectors; an anode in said lamp envelope and electrically coupled to one of said high voltage output connectors and a cathode in said envelope in predetermined spaced relation to said anode, said cathode being electrically coupled to the other of said high voltage output connectors; coupling means for coupling said input connectors of said ballast to a low voltage DC power source; a sealed waterproof and pressure resistant enclosure for said ballast surrounding said ballast and providing a means for electrical insulation for said ballast and for the high voltage output connectors between said lamp and said ballast, said enclosure including a molded electrically insulating and thermally conductive mass conformed around said ballast to function as a heat sink for dissipating heat from said ballast to the exterior of said enclosure; and a waterproof protective cover for said lamp mounted on said enclosure in sealed relation thereto, said cover sealing said lamp from the surrounding environment and including at least a portion which is translucent so as to pass light from said lamp into such environment.
