Abstract
Systems, methods and devices for lighting are provided with a reflector with paraboloidal segments. One lighting system includes a reflector having one or more reflector segments. Each reflector segment is substantially paraboloidal and has a central axis of syrmetry. The lighting system also includes an illumination portion having one or more light sources. Each light source corresponds to one of the reflector segments and has a central illumination axis. The central illumination axis is directed toward the corresponding segment and substantially perpendicular to the central axis of symmetry of the corresponding segment.
