Lighting system including visible-light source with semiconductor light-emitting device, which may further include: pan assembly having pan ring, pinion gear, and central fixed gear; heat-sink, tilt assembly including tilt adjustment screw, leadscrew, and two spaced-apart panels defining tilt path for causing movement of heat-sink and visible-light source along tilt path; universal joint assembly including gimbal, swing bar with swing arms and being in threaded engagement with leadscrew, swing arms connected with visible-light source; support assembly configured for securing heat-sink and visible-light source together at plurality of selectable distances away from light emission aperture; heat-sink and visible-light source each having thermally-conductive surface, one surface having Dzus-type fastener button and another surface having Dzus-type cavity containing spring wire, for reversible attachment of heat-sink and visible-light source together; or power supply assembly, and receptacle for self-aligning reversible installation of power supply assembly, receptacle having guide walls with lead-ins.

Boundary-mountable lighting systems

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.

Lighting systems generating partially-collimated light emissions

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.
