Heat extractor device for fluorescent lighting fixture
Abstract:
A lamp heat extractor device for lowering the cold spot temperature of a fluorescent lamp includes a base portion adapted to be attached to a heat conductive portion of the fluorescent lighting fixture proximate the fixture's lamp socket or sockets, and an extended sleeve end portion thermally connected to the base portion by a conductive connector portion. The conductive connector portion positions the extended sleeve portion so that it contacts the cold spot end of the fluorescent lamp or lamps held by the lamp sockets of the fixture to allow heat transfer to the fixture housing to which the heat extractor device is attached. Suitably, the outer surface of the extended sleeve end portion of the heat extractor device can have a plurality of radially extending fins for increasing surface area for heat radiation from the extended sleeve portion, thereby increasing the overall heat extracting efficiency of the device. The device can have two or more sleeve ends thermally interconnected to the base portion for contacting the cold spot ends of two or more fluorescent lamps.
