    摘要: Optical films are disclosed, which have a structured surface including a plurality of concave pyramid-shaped structures, each structure having a base including at least two first sides and at least two second sides. In addition, optical devices are disclosed that incorporate the optical films, for example, such that a first surface of the optical film is disposed to receive light from a light source and the structured surface faces away from the light source.

    摘要: A light guide including a light guide body having a light re-directing side positioned opposite from a light output side. A plurality of elongate prisms are located adjacent the light output side of the light guide body. The prisms extend side-by-side relative to one another along lengths. The prisms include upper edges defining heights of the prisms. The upper edges extend along the lengths of the prisms. Each upper edge includes a plurality of edge segments having different magnitudes of slope. The light guide also includes a plurality of light extraction structures located adjacent the light re-directing side of the light guide body for reflecting light toward the light output side. The light extraction structures include elongated projections each having a plateau segment and first and second facets. The elongated projections are separated by lands that are recessed relative to the plateau segments. The first and second facets extend from the plateau segments to the lands.

    摘要: An optical film having a substrate and microreplicated features on a major surface of the substrate. The features include microreplicated macro-scale features and one or more microreplicated diffractive features on the macro-scale features. The films can be made from work pieces machined with tool tips having diffractive features. The tool tip forms both the macro-scale features and diffractive features while machining the work piece. A coating process can then be used to make the optical films from the machined work piece.

    摘要: The present disclosure is directed to backlighting systems, which include first and second lightguides, at least one light source optically connected to an edge of the first lightguide and at least one light source optically connected to an edge of the second lightguide for supplying light into their respective interiors. In the appropriate exemplary embodiments, the backlighting systems of the present disclosure include an extractor disposed at a surface of the second lightguide for diffuse extraction of light from the interior of the second lightguide. In such exemplary embodiments, at least a portion of the light supplied into the interior of the second lightguide and then diffusely extracted therefrom enters the interior of the first lightguide through a substantially optically clear surface. In some exemplary embodiments, the backlighting systems of the present disclosure include recycling enhancement structures, which may be attached to the first lightguide.
