Abstract: An area optical cover for a linear light source extends along an axial direction. The optical cover includes a portion of an optical material that forms a constant cross-section transverse to the axial direction. An outer surface of the cross-section is substantially planar, and an inner surface of the cross-section forms a plurality of facets. Each of the facets forms a refractive surface that is configured to refract a corresponding portion of light from the light source, and a return surface that connects the refractive surface with a refractive surface of an adjacent facet. When the outer surface is oriented horizontally on a lower side of the portion of the optical material, and the linear light source is positioned at an installation height above the inner surface, all facets within at least 30 degrees of nadir from the light source are optimized to provide a selected light distribution.
