Zusammenfassung: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.
