  • Luminaire for assembly line
    Patent number: 4254456
    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.
