    Abstract: An optic having a first optic portion located on a first side of the optic and a second optic portion formed integrally with the first optic portion and located on a second side of the optic. A first cavity is defined by a first cavity inner surface in the first optic portion, the first optic portion being configured to refract light rays emitted by at least one light source. The second optic portion includes at least one total internal reflection surface and a second cavity defined at least partially by a second cavity rear surface that extends at an angle between 20° and 60°, inclusive, relative to an axis defining the height the of the optic. The second cavity rear surface is configured to refract other light rays toward the at least one total internal reflection surface, and the at least one internal reflection surface is configured to reflect the light rays toward the first side of the optic.

    Abstract: FIG. 1 is an isometric view, as seen from a first angle, of an optical cover with faceted surface;
    FIG. 2 is an isometric view, as seen from a second angle, of the optical cover with faceted surface of FIG. 1;
    FIG. 3 is an end elevation of the optical cover with faceted surface of FIG. 1, an opposing end elevation thereof being identical;
    FIG. 4 is a front elevation of the optical cover with faceted surface of FIG. 1, a rear elevation thereof being identical;
    FIG. 5 is a cross-sectional view of the optical cover with faceted surface of FIG. 1, taken at cross-sectional plane 5-5′ indicated in FIG. 4; and,
    FIG. 6 is a bottom plan view of the optical cover with faceted surface of FIG. 1.
    Bold broken lines indicate the bounds of the claim. Light weight broken lines illustrate portions of the optical cover with faceted surface; all broken lines form no part of the claimed design.

    Abstract: An optic for aisle lighting includes a portion of an optical material defined by a length and a cross-sectional profile. The cross-sectional profile is characterized by a cavity within the optical material, two upwardly-facing surfaces of the optical material on opposite sides of the cavity from one another, and downwardly-facing surfaces of the optical material. The cavity is bounded by an upward facing aperture, and at least three faces of the optical material that meet at interior angles. Light received through the upward facing aperture is separated at the interior angles, and refracted by the faces of the optical material, into separate light beams equal in number to the faces. The two upwardly-facing surfaces internally reflect the separate light beams downwardly. The downwardly-facing surfaces intercept respective portions of the separate light beams, and refract the portions as they exit the optic.

    Abstract: A light fixture for lighting a surface includes a housing, a plurality of light sources, and a molded optic through which light from the light sources is directed. The molded optic further includes a plurality of concave aspheric optical surfaces in a first side of the molded optic, each of the concave aspheric optical surfaces partially enclosing one or more of the plurality of light sources, wherein the aspheric concave optical surfaces receive light directly from the respective light sources, and a plurality of convex aspheric optical surfaces disposed respectively opposite the plurality of concave aspheric optical surfaces on a second side of the molded optic, opposite the first side. The light sources and the aspheric optical surfaces cooperate to direct light onto the surface in an illumination field that is generally rectangular.
