Abstract: An optical system includes an optical film curved about a first axis and a light control film curved about the first axis and substantially coextensive with the optical film. The optical film includes a first layer including a microstructured first major surface where the microstructured first major surface defines a linear Fresnel lens including a plurality of Fresnel elements extending along the first axis. The first major surface of the optical film faces the light control film. The light control film includes a plurality of spaced apart optically absorptive regions extending along the first axis and along a direction substantially normal to a major surface of the light control film. At least one of the optical film or at least one layer disposed between the optical film and the light control film includes at least one reflection mitigation element.

Abstract: Extended area lighting devices include a light guide and diffractive surface features on a major surface of the light guide. The diffractive surface features provide low distortion for viewing objects through the light guide. Light from discrete light source(s) is injected into the light guide, and the diffractive surface features interact with the injected light to couple guided-mode light out of the light guide. The out-coupled light produces one or more bands whose apparent shape changes with viewing position. The bands may be bright bands that correspond to the discrete light sources, or dark bands associated with an optional non-uniform reflective structure extending along a side surface of the light guide. Multiple bands may form a pattern that changes with viewing position, the pattern of bands having a 3-dimensional appearance for at least some viewing positions. The lighting devices can be used as luminaires for general lighting or decorative lighting.

Abstract: Lighting systems and devices include a light-transmissive tube and a light source assembly. The light-transmissive tube defines a cavity that extends along a longitudinal axis, at least a portion of the tube having an inner structured surface facing the cavity, and an outer structured surface facing away from the cavity. The light source assembly is disposed to inject light into the cavity, and includes one or more discrete light sources such as LED sources. The inner and outer structured surfaces of the tube are configured to direct a first portion of the injected light out of the tube through the outer structured surface and to direct a second portion of the injected light back into the cavity, such that a virtual filament, or pattern of virtual filaments, appears in the tube.

Abstract: This application describes a back-lit transmissive display including a transmissive display and a variable index light extraction layer optically coupled to a lightguide. The variable index light extraction layer has first regions of nanovoided polymeric material and second regions of the nanovoided polymeric material and an additional material. The first and second regions are disposed such that for light being transported at a supercritical angle in the lightguide, the variable index light extraction layer selectively extracts the light in a predetermined way based on the geometric arrangement of the first and second regions. The transmissive display may be a transmissive display panel or a polymeric film such as a graphic.
