    摘要: A diffusive reflector for a lighting apparatus comprising a backing part upon a surface of which is disposed an interface part(s) wherein the interface part(s) is at least partially diffusively reflective optically and/or the backing part is diffusively reflective optically. The interface part(s) is formed with a plurality of separate protrusions each adapted for making a separate respective contact interface with a surface of a light guide panel of the lighting apparatus to optically couple the backing part to the light guide panel via the interface part(s). The interface part(s) comprises an optically transmissive interface material arranged to form said contact interface such that the interfacial energy thereof is reduced so that air is driven from the contact interface. Consequently, the critical angle for total internal reflection of light guided by the light guide panel is increased at said contact interface.

    摘要: An imaging directional backlight apparatus including a waveguide, a light source array, for providing large area directed illumination from localized light sources. The waveguide may include a stepped structure, in which the steps may further include extraction features optically hidden to guided light, propagating in a first forward direction. Returning light propagating in a second backward direction may be refracted, diffracted, or reflected by the features to provide discrete illumination beams exiting from the top surface of the waveguide, in operation, luminance streaks and bright illumination regions may be formed due to undesirable imaging characteristics from the structure of the Fresnel mirror. Fresnel mirror draft facets and reflective facet microstructures are provided that achieve reduction of visibility' of light streaks and bright illumination regions.

    摘要: An imaging directional backlight apparatus including a waveguide, a light source array, for providing large area directed illumination from localized light sources. The waveguide may include a stepped structure, in which the steps may further include extraction features optically hidden to guided light, propagating in a first forward direction. Returning light propagating in a second backward direction may be refracted, diffracted, or reflected to provide discrete illumination beams exiting from the top surface of the waveguide. Viewing windows are formed through imaging individual light sources and defines the relative positions of system elements and ray paths. The uncorrected system creates non-illuminated void portions when viewed off-axis preventing uniform wide angle 2D illumination modes. The system may be corrected to remove this non uniformity at wide angles through the introduction of additional sources away from the system's object plane, additional imaging surfaces, and/or by altering ray paths.

    摘要: Lightguides and methods for making and using the same are disclosed. A structured layer is provided with light extractors formed on a structured surface thereof. In some cases, the structured layer is removably laminated onto a substrate to provide uniform light extraction. In some cases, indicia are cut out of the structured layer and laminated onto the substrate. In some cases, the structured surface of the structured layer is selectively filled to form a pattern for light extraction. In some cases, a tool for producing a structured layer has a region of structures selectively filled to form a pattern for light extraction on the produced structured layer.
