Abstract
A lamp holder assembly for use in thin profile lighting fixtures having fluorescent lamps wherein there is a narrow gap between the lamps and the reflector so that accessing the lamps is difficult. The lamp holder assembly pulls out so that access can be gained to the lamps. The lamp holder assembly comprises a base member and a bracket member with lamp sockets affixed to the bracket member.
The bracket member slides against the base and is held in position on the base by slots in the bracket member that engage guide pins extending from the base.
Further guidance for the bracket member may include twin parallel rails extending form the base and spaced so as to form a channel in which the bracket member travels. The pull-out assembly may also have a leaf spring attached to the base member that further guides the bracket member while in motion.
The bracket member slides against the base and is held in position on the base by slots in the bracket member that engage guide pins extending from the base.
Further guidance for the bracket member may include twin parallel rails extending form the base and spaced so as to form a channel in which the bracket member travels. The pull-out assembly may also have a leaf spring attached to the base member that further guides the bracket member while in motion.
