Abstract:
1. A display light fixture comprising: a lamp housing, a mounting bracket, lamp housing support arms which extend between the mounting bracket and the lamp housing, the lamp housing and lamps therein spaced from the mounting bracket and configured for placement in connection with a display to position a light source generated by the lamps in front of or remote from a display to achieve broad illumination of a display; the lamp housing configured and dimensioned to house at least one T-5 type lamp which has a generally elongate and cylindrical shape and electrical contacts at each end in the form of a metal cap through which extend two electrically conductive pins; the T-5 type lamp housing having a generally elongate and cylindrical shroud which substantially surrounds the T-5 type lamp, and an opening which runs a substantial length of the shroud and through which at least of portion of the lamp is exposed; a shroud end cap fitted at each end of the lamp housing, each shroud end cap having a generally cylindrical body and one or more internal braces which extend transverse across a width of the cylindrical body; axial passages through the internal braces for serial wiring or other interconnection; interconnection tabs extending in an axial direction from both ends of the cylindrical body configured to fit within the cylindrical body of an aligned and adjoining shroud end cap of another display light fixture in a flush serial fitting arrangement; and an opening for receiving an end of one of the lamp housing support arms; a T-5 type lamp receptacle located within each of the shroud end caps, each of the T-5 type lamp receptacles having first and second cooperating components which are spring-biased to enable collapse to a smaller profile which increases the clearance room for insertion of a T-5 type lamp into the fixture, the first component having a body wall, extensions which extend from the body wall, and locking tabs at distal ends of the extensions, a first component spring boss which also extends from the body wall and generally between the extensions, the spring boss receiving and aligning a spring in an orientation generally perpendicular to and extending away from the body wall and generally parallel to the extensions; a second component which fits with the first component and which has a main wall which is oriented parallel with the body wall of the first component and a perimeter wall which fits within the body wall of the first component and is engaged with the locking tabs of the first component, a second component spring boss which extends perpendicularly from the main wall and configured to receive an end of a spring in the second component spring boss, locking tabs which extend from the perimeter wall and which are biased against locking tabs of the first component by the spring, the spring extending into a spring boss in the interior of the second component; a main wall of the second component oriented to face an interior of the fixture, opposed to a facing lamp receptacle; first and second terminal guards extending generally axially from the main wall and spaced apart for receiving a terminal end of a T-5 type lamp, and terminal lead passages in the main wall for receiving electrical contact pins of the terminal end of the T-5 type lamp, the mounting bracket having a generally elongate body with a length dimension generally equivalent to a length dimension of the lamp housing, the lamp housing support arms extending generally laterally from ends of the mounting bracket; first and second mounting blocks which fit together within the mounting bracket to engage and support the support arms, each mounting block having a body and a half-tunnel formed on an interior side of the body to form a cylindrical bore in which an end of a support arm is held; the mounting bracket formed by first and second cooperating channels, the first channel in the general configuration of U-shaped channel, with parallel walls and a connecting wall, the second channel having a main wall which spans between the parallel walls and an end wall.
