    摘要: 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. First base includes central region having convex paraboloidal-shaped surface and second peak facing toward visible-light source.

    摘要: A lamp includes an extended planar light source, and an optical element arranged with the light source, wherein the optical element comprises an outer surface having an indented cusp substantially over the light source. A lamp includes an extended planar light source, and an optical element arranged with the light source, wherein the optical element comprises an outer surface having a portion at a peripheral edge comprising a curvature configured to redirect light emitted from the light source by total internal reflection.
