Abstract

Lighting system. Bowl reflector has rim defining horizon and aperture, first light-reflective surface defining cavity, first parabolic surface. Funnel reflector has flared funnel-shaped body: central axis; second light-reflective surface aligned along axis; second parabolic surface; tip located within cavity along axis; profile including parabolic curves converging towards tip. Optically-transparent body aligned with second light-reflective surface along axis; with: bases spaced apart by side surface; first base facing light source. Second parabolic surface has ring of focal points at first position within cavity, equidistant from second parabolic surface; ring encircles first point on axis. Second parabolic surface has axes of symmetry intersecting with and radiating in directions all around axis from second point. Axes of symmetry intersect with focal points. Second point on axis between first point and horizon. Light source located for causing light emissions reflected by second parabolic surface to have partially-collimated distribution.
