摘要： Elongated lighting system comprises an elongated light pipe having first and second ends, with light supplied to those ends by at least one light source, via first and second light couplers that condition light to increase reflections within the light pipe. Light-extraction structure on the light pipe extracts light from the side of the pipe. An indentation in the light pipe has a depth and has surfaces oriented with respect to the pipe so as (1) to redirect light from the first light source that reaches the indentation after passing once through a plane adjacent the indentation, back through the plane and towards the first end; and (2) to sufficiently increase the average angular distribution of light reflected from the indentation and passing back through the plane as would cause at least 50 percent more reflections of the foregoing light within the pipe in the absence of the light-extraction structure.

The light pipe has light-extraction structure along a first longitudinal side of the luminaire, which is confined to a radial swath of the luminaire, along the longitudinal axis of the luminaire, of substantially less than 180°. For efficiency, the second end has light-saving structure for directing saved light from the second end towards the first end, at redirection angles other than an excluded range of redirection angles, so long as the photon content of light at so-called alpha redirection angles is at least 10 percent of the photon content of light at so-called beta redirection angles, where the excluded range of redirection angles is defined by: |βr↑

摘要： Lighted display case with remote light source comprises a container having contents for display. A solid fiber optic luminaire is at least partially mounted within the container, having an elongated side-light emitting portion for emitting light from the side of the luminaire onto contents in an interior of the display case. The side-light emitting portion comprises an extractor of light arranged to preferentially extract light from the luminaire and direct the light to at least one target area of said contents. The portion may be rotatable about its own longitudinal axis. A single side-light emitting portion may be arranged to illuminate a target area on one of its lateral sides, and another target area on another lateral side. A single lamp may provide light to first and second luminaires arranged to illuminate a target area on one of its lateral sides, and another target area on another lateral side.

摘要： A luminaire with improved lateral illuminance control comprising a light pipe with a longitudinal center is disclosed. A light-extraction means applied to a radial swath of the light pipe has a longitudinal portion having dimension along its length, centered about a slice on the light pipe longitudinally; said slice being orthogonal to the longitudinal center and located in a propagation plane through which light propagates to a virtual target area intersecting the propagation plane. The light pipe intervenes between the radial swath and the target area. A first average efficiency point of the light-extraction means corresponds to the minimum distance to the target area being at least approximately 20% less than a respective, second average efficiency point corresponding to a respective maximum distance to such area. The light-extraction means efficiency varies from the first average efficiency point to the second average efficiency point though more than one non-zero value.

摘要： A solid light pipe arrangement with reduced Fresnel-reflection losses includes a light pipe with a solid core comprising a polymer. An optically clear substrate has first and second sides with an anti-reflective coating on at least one side. The substrate is adhered to an end-face of the core of the light pipe by adhesive material so as to create an optically clear interface between the substrate and the end-face that passes more than about 96 percent of transmitted light. A preferred method of applying an anti-reflective coating to an end-face of a core of a solid, polymeric light pipe comprises diverting uncrosslinked polymer used for forming a light pipe core, and using the diverted polymer as adhesive material between a substrate with at least one antireflective coating and the end-face of a light pipe having the same polymeric components, in the same proportions, as the diverted polymer.
