Luminaire for assembly line

A luminaire comprising, in combination, a housing having a front opening, a concave main reflector mounted within said housing facing said front opening, said main reflector comprising a pair of curved rear sections arranged on opposite sides of a vertical median plane intersecting said main reflector and a pair of forward reflector sections extending forwardly from said rear sections and defining a reflector opening, an auxiliary reflector interposed between said main reflector and said reflector opening and comprising a pair of reflector sections arranged on opposite sides of said vertical median plane respectively facing said pair of curved rear sections of said main reflector and having opposite lateral edges spaced from said forward reflector sections, and means for mounting a light source substantially in said plane in the space between said rear and auxiliary reflector sections, so that light rays from the light source incident on said auxiliary reflector are redirected thereby to said curved rear sections of said main reflector for reflection therefrom outwardly through said front housing opening on opposite sides of said vertical median plane, the arrangement of said rear reflector sections and said auxiliary reflector sections relative to the light source being such that light rays reflected forwardly from said rear reflector sections pass substantially entirely through the space between said auxiliary reflector sections and said forward reflector sections without additional reflection.
