Abstract
An optical cover for a linear light source includes a portion of an optical material that forms a cross-section transverse to an axial direction. The cross-section curves so that its inner surface is substantially concave and its outer surface is substantially convex. The outer surface is substantially smooth, and the inner surface forms facets. Each of the facets refracts light, and connects with an adjacent facet. Each of the facets defines a peak height from the outer surface, and each pair of adjacent facets defines a valley height from the outer surface. The peak heights of all facets exceed the valley heights between adjacent pairs of facets, and the peak height of each selected facet does not exceed twice the valley height between the selected facet and a facet adjacent to the selected facet.
