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.

摘要： Fiberoptic luminaire with scattering and specular side-light extractor patterns comprises a fiberoptic light pipe with elongated side-fight emitting portion. Such portion illuminates a target area with a scattering, and a specular, light extractor pattern. The extractor patterns are arranged to extract light from the side-light emitting portion over a radial angle, orthogonal to said main axis, of less than 180°. The scattering extractor pattern atone may provide greater than 50% of light on the target area, and light extracted by the specular extractor pattern alone may produce an illuminance on a selected portion of the target area that is greater than 5% of the maximum illuminance produced on the target area by the scattering extractor pattern. Furthermore, the scattering extractor pattern may comprise a Lambertian type of extractor pattern. Each specular extractor pattern may comprise a notch having main faces parallel to within 10° of each other.

摘要： A light pipe with side-light extraction by light pipe-surface alteration includes an optical light pipe with a plastic light-carrying portion covered with a fluoropolymer cladding. A plurality of light-extraction devices is spaced along an active section of the light pipe for emission of side light over only a range from about 2 to 270 degrees of the cross-sectional circumference of the light pipe in the active section. The light-extraction devices have inlets passing through the cladding and optically contacting the plastic light-carrying portion. Another form of light pipe with side-light extraction by light pipe-surface alteration includes an optical light pipe with a plastic light-carrying portion. An active section of the light pipe for side light emission comprises an axisymmetrical change of area of cross section of the light pipe that generally diminishes from an inlet end of the active section, through the active section.

摘要： A light pipe with directional side-light extraction comprises a light pipe and light-extraction structure applied to the light pipe over only a part of the cross-sectional perimeter of the light pipe and over an active section of the length of the light pipe in which directional side lighting is desired. The light-extraction structure comprises any of (i) material, other than a light-carrying portion of the light pipe or any fluoropolymer cladding on the light-carrying portion, including light-scattering material, (ii) surfaces treated to have light-scattering properties, and (iii) material with a reflective property. The foregoing light pipe eliminates the need for using a reflector, as with fluorescent lamps, by extracting the light only in the desired direction, towards a target area to be illuminated. Other embodiments of the invention promote uniformity in side light emission from a light pipe.
