Abstract
Luminaires for illuminating a target zone having target zone subregions in front of and to the sides of the luminaire. The luminaire includes a housing, a lamp holder in the housing positioned to support an electric lamp in a generally vertical orientation, and a compound parabolic reflector in the housing partially surrounding a lamp light-emitting segment location having plural regions. Preferred forms of the compound parabolic reflector include segmented center and side portions. The preferred segmented center portion has a first plurality of two-dimensional parabolic segments each of which has a focal point in a different one of the plural light-emitting segment location regions. The preferred segmented side portions are each provided with a second plurality of two-dimensional parabolic segments having focal points along the light-emitting segment location. The parabolic segments are effective to direct a preponderance of light toward the plural target zone subregions.
