  • Patent number: 11614217
    Abstract: Lighting system including bowl reflector, visible-light source, central reflector, and optically-transparent body. Bowl reflector has central axis, and rim defining emission aperture, and first visible-light-reflective surface defining portion of cavity in bowl reflector. First visible-light-reflective surface includes parabolic surface. Visible-light source is located in cavity and configured for generating visible-light emissions from semiconductor light-emitting device. Central reflector includes second visible-light-reflective surface, having convex flared funnel shape and having first peak facing toward visible-light source. Optically-transparent body has first base being spaced apart from second base and having side wall extending between first and second bases. Concave flared funnel-shaped surface of second base faces toward convex flared funnel-shaped second visible-light reflective surface of central reflector.

  • Patent number: 10801696
    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.
