ABSTRACT:
An elongated high intensity lamp which serves as a line-type of light source is placed at the focus of a generally shaped parabolic reflector which extends longitudinally with the light source. The reflector surface closest to the lamp is inwardly deformed toward the light source. The inwardly deformed section may itself be a concavely shaped parabolic or arcuate region; or inwardly angled flat sections; or a flat region extending squarely across the top of the reflector. The distortion of the parabolic reflector shape produces a more uniform intensity distribution across the area being illuminated by the lamp and the reflector. A plurality of parallel line-type sources are also disclosed.
