Abstract: Light-emitting devices can include a package that supports one or more light-emitting die (e.g., light-emitting diode die, laser diode die) and which can ensure mechanically stability, can facilitate electrical and/or thermal coupling with light-emitting die, and can manipulate the manner by which light generated by the die is emitted out of the light-emitting device. The package can also facilitate the integration of the light-emitting devices in various components and systems. For example, suitable packages may facilitate the use of light-emitting devices in components and systems such as light-emitting panel assemblies, LCD back lighting, general lighting, decorative or display lighting, automotive lighting, and other types of lighting components and systems.

Abstract: Optical assembly includes a generally planar light output surface located on a first major plane, and a generally planar second surface located on a second major plane approximately parallel to the first major plane and superimposed thereon. Both the light output surface and the second surface have respective first and second patterns of well defined optical elements that are quite small in relation to the length and width of the optical assembly. The optical elements of the first pattern have an apex angle formed by a first sloped surface that is larger in an area closer to at least one light input edge of the optical assembly and smaller in another area further away from the light input edge.

Abstract: Illumination assemblies, components, and related methods are described. An illumination assembly is provided that comprises a plurality of illumination tiles each having a light emission surface. The plurality of illumination tiles are arranged in a two-dimensional array. The illumination tiles are constructed and arranged so as to provide a substantially contiguous illumination surface comprising the light emission surfaces of the plurality of the illumination tiles. Each illumination tile is illuminated by at least one solid state light-emitting device. A method of local dimming an illumination assembly of a display (e.g., LCD) backlight unit is also provided.

Abstract: A method of forming a varying pattern of optical elements on or in at least one side of an optical panel member involves cutting or forming a pattern or patterns of cavities in a cylindrical or curved substrate or in a sleeve or sleeve segment of the substrate that corresponds to a desired pattern and shape of optical elements to be formed on or in the optical member. The substrate or sleeve or sleeve segment containing the desired pattern or patterns of optical element shaped cavities or depositions or mirror copies or inverse copies thereof is used in production tooling or as a master for production tooling to form the corresponding pattern of optical elements on or in at least the one side of the optical panel member.

Abstract: Light emitting assembly includes an optical conductor having a pattern of deformities on or in front and back sides of the optical conductor to cause light to be emitted from a light emitting surface on at least one of the sides. At least one of the deformities varies, and at least one planar or curved refractive surface is aligned with at least one light source to redirect a portion of the light from the light source entering the optical conductor in a predetermined manner to cause the light emitted from the light emitting surface to pass through an optical film, which redirects the light through a liquid crystal display with no loss.

Abstract: Illumination systems, which include at least one light source (e.g., LED and/or laser diode), light sensor, and a power source are described. In certain embodiments, a light sensor and a microprocessor are used to detect light emitted by a light source and to adjust the power signal provided to the light source at least partially based on the detected light. Some embodiments may enable the color point and/or brightness of the emitted light to be controlled at least partially based on the detected light. The illumination systems may be designed to be used as a liquid crystal display (LCD), general lighting apparatus, or any other illumination device.

Abstract: Light redirecting film systems comprise a backlight having deformities that cause a majority of the light entering the input edge of the backlight to be emitted from a light output surface of the backlight. In close proximity to the light output surface is a light redirecting film that has a pattern of individual optical elements of well-defined shape to redistribute the light emitted by the light output surface toward a direction normal to the film.

Abstract: The transreflectors may comprise a transparent substrate having reflective surfaces and other light transmissive surfaces for respectively reflecting and transmitting a greater portion of the light striking opposite sides of the substrate. Alternatively, the transreflectors may comprise two or more transparent substrates of different indices of refraction bonded together, with a pattern of optical deformities in the mating side of one of the substrates and an inverse pattern of optical deformities in the mating side of an other substrate in mating engagement with each other. The transreflectors are used in a transreflector system or display to transmit more of the light emitted by a backlight or other light source incident on one side of the transreflectors and reflect more of the light incident on the opposite side of the transreflectors. The transreflectors and backlight may be tuned to each other to enable the transreflectors to better transmit more of the light emitted by the backlight.

Abstract: Light emitting assembly includes at least one film, sheet, plate or substrate positioned between a light source and a display for redirecting at least some of the light emitted by the light source. One side of the film, sheet, plate or substrate may have a pattern of reflective or refractive surfaces or deformities and the other side may have corresponding or aligned optical deformities of well defined shape. Light emitted from the light source that strikes a reflective or refractive surface or deformity on the one side of the film, sheet, plate or substrate passes through the film, sheet, plate or substrate and is redirected by at least one corresponding optical deformity on the other side of the film, sheet, plate or substrate.

Abstract: An electromechanical dynamic force profile articulating mechanism for recovering or emulating true parallel plate capacitor actuation behaviors from deformable membranes used in MEMS systems. The curved deformation of flexible membranes causes their MEMS behavior to deviate from known interactions between rigid plates that maintain geometric parallelism during ponderomotive actuation.
