Abstract:
1. A display lighting system for illuminating a shelving structure comprising: a luminaire having a unitary lamp housing forming two linear lamp cavities along a central longitudinal axis between a pair of spaced opposed end caps, wherein a separate one of said end caps fully covers adjacent axial distal ends of said linear lamp cavities a pair of spaced arms each secured at a first end directly to said separate one of said end caps for positioning said display lighting system, wherein each of said spaced arms is positioned perpendicular to said central longitudinal axis of said linear lamp cavities each one of said end caps having a recess perpendicular to said central longitudinal axis and extending from only a portion of an outside edge of said end cap and across an outside surface of said end cap to a distance offset from said portion of said outside edge of said end cap whereby a remainder of said outside surface of said end cap remains laterally to the left and right of said recess, at least one of said recesses of said end caps having an aperture extending through from said recess to an inside surface of said end cap and substantially parallel to said central longitudinal axis of said linear lamp cavities for routing conductors therethrough and in electrical communication with a plurality of lamp holders, and said unitary lamp housing having said plurality of lamp holders secured between said pair of spaced opposed end caps for providing electrical power to a plurality of lamps, and for securing and positioning said lamps to illuminate from said two linear lamp cavities, one of said linear lamp cavities having at least one reflector secured thereto to reflect illumination from at least one of said plurality of lamps whereby one of said linear lamp cavities illuminates downwardly and inwardly towards a first target area and said other linear lamp cavity illuminates upwardly and inwardly towards a second target area, wherein said first target area is substantially exclusive from said second target area; and said recess of each one of said end caps directly receives said first end of said spaced arms to positively fix the mounting angle of said luminaire with respect to said first target area and said second target area since said remainder of said outside surface of each said end cap prevents rotation of said luminaire.
