    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 illumination system includes a light guide for distributing light. Extraction structures are provided to uniformly extract light from the light guide. The structures extract more light out of the light guide when light is propagating in the light guide in a direction toward the light input area than when light is propagating in the light guide in a direction away from the light input area.

    摘要: Methods for fabricating an optical film characterizable by a relationship between gain and thickness to prism pitch ratio (S/p) that varies cyclically are described. The thickness and the prism pitch of the optical film are selected based on the relationship between gain and S/p ratio, to obtain a desired gain. The optical film is formed having the S/p ratio that provides the desired gain.
