Energy reduction optics

A light fixture for lighting a surface, the light fixture comprising:

• a housing;
• a plurality of light sources;
• and
• a molded optic through which light from the light sources is directed, the molded optic further comprising:
• 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 enclosed 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;
• wherein the light sources, the concave aspheric optical surfaces, and the convex aspheric optical surfaces cooperate to direct light produced by the light sources onto the surface in an illumination field that is generally rectangular;
• and wherein the molded optic comprises a textured surface on the second side of the molded optic, between at least some of the convex aspheric optical surfaces.

A molded optic, comprising:

• a plurality of concave aspheric optical surfaces in a first side of the molded optic;
• 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, wherein the convex optical surfaces are at least partially briquette-shaped, having a rounded profile with extended rounded corners;
• and
• a smooth surface on the first side of the molded optic, between at least some of the concave aspheric optical surfaces, wherein the smooth surface is smooth enough that light encountering the smooth surface reflects from the smooth surface by total internal reflection;
• wherein each of the concave aspheric optical surfaces cooperates with its respective convex aspheric optical surface to direct light produced by a light source at least partially enclosed by the concave aspheric optical surface onto a surface in an illumination field that is generally rectangular but has lobes of illumination at the corners extending beyond the boundaries of the otherwise-rectangular field shape.
