    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: A display system includes a pixelated display being curved about at least one axis and including a plurality of groups of pixels; a plurality of light redirecting elements where each light redirecting element corresponds to a different group of pixels in the plurality of groups of pixels; and an optical lens system adapted to receive light emitted by the pixelated display and transmitted by the plurality of light redirecting elements. The optical lens system transmits at least a portion of the received light. For at least one pixel in the plurality of groups of pixels, the light redirecting element corresponding to the pixel reduces an angle between a central light ray emitted by the pixel and a chief light ray emitted by the pixel.

    Abstract: A multilayer optical film includes a plurality of polymeric first layers numbering at least 10 in total where each of the first layers has an average thickness less than about 500 nm. For a p-polarized incident light, and for each of a first incident angle and a second incident angle greater than the first incident angle by at least about 40 degrees: a reflectance of each of the optical film and the plurality of polymeric first layers versus wavelength has a reflection band having a left band edge (LBE) at a short wavelength side of the reflection band and a right band edge (RBE) at a long wavelength side of the reflection band. A separation between the RBEs is less than a separation between the LBEs for the first incident angle, and a separation between the RBEs is greater than a separation between the LBEs for the second incident angle.

    Abstract: An optical stack for reflecting and transmitting light in a predetermined wavelength range includes stacked first and second optical films, the predetermined wavelength range defining a first wavelength range and a remaining wavelength range. For normally incident light and for each wavelength in a first wavelength range, the first optical film substantially reflects light having a first polarization state, and substantially transmits light having a second polarization state. For each of the first and second polarization states, for wavelengths in the first wavelength range, the second optical film has a maximum optical transmittance Tmax for light incident at a first incident angle, and an optical transmittance Tmax/2 for light incident at a second incident angle, where the second incident angle is greater than the first incident angle by less than about 50 degrees. For wavelengths in the remaining wavelength range, the second optical film reflects at least 80% of light.

    Abstract: An optical film (100) includes a plurality of polymeric layers (40) disposed between opposing first (11) and second (12) outer layers, a thinnest polymeric layer in the plurality of polymeric layers disposed closer to the first outer layer (11) and a thickest polymeric layer disposed closer to the second outer layer (12). A layer thickness gradient of the optical film (100) includes first (43) and second (45) portions joined by a step portion (20), a change in thickness across the step portion (20) at least 5 times greater than a change in thickness across each of the first (43) and second (45) portions, wherein the optical film (100) has a first average transmission percentage, TA1, in a first wavelength range, a peak transmission percentage, Tp, in a different, second wavelength range. The first wavelength range and the second wavelength range are separated by a third wavelength range with a third average transmission percentage, TA3, such that TA1>Tp>30(TA3).
