ABSTRACT:
Luminaire with high intensity gaseous discharge lamp for illuminating a work area such as an automobile assembly line. The lamp is arranged between a concave main reflector and an auxiliary reflector facing the central portion of the main reflector. The arrangement is such that it provides adequate light control to efficiently illuminate the work area while shielding the lamp from direct view of the worker and reducing shadows on the work area due to the worker being positioned between the work and the luminaire.
