Abstract
The output of a segmented filament lamp is smoothed and made more uniform by placing a reflector assembly adjacent the lamp, the reflector assembly comprising a plurality of joined specular hybrid cylindrical/roof mirror segments. Each segment is located so as to reflect light from a portion of each filament back into the filament plane to form an image of each filament in interfilament space. The lamp output thus appears as a uniform and constant source. This type of improved filament lamp is especially useful in conjunction with an imaging system which requires a very uniform light level at a projection lens or at the surface of a document platen.
