Abstract

A hinged bracket for permitting the swinging away, within limits, of at least one socket to permit easy access to an elongated, doubled-ended bulb for relamping purposes, the relamping apparatus holding the bulb firmly enough to prevent its dropping out of the sockets. The sockets are each spring-loaded and partly biased against the bulb in the open relamp position and firmly biased against the bulb in the position of use. A heat sink is also provided via a sleeve extension on the socket and a mating hump on the door which provides access, when removed, to one of the bulb sockets through relatively small openings in the fixture and the nearby reflector. The swinging away of the socket to one side of these openings provides easy access to the bulb that would not otherwise be possible.
