Abstract
A transparent shallow gently bulging substantially spherical segmental shield formed of polycarbonate resin protects a planar lens mounted in an aperture in a door of a conventional low profile streetlight. The shield shell is generally of the shape of a convex spherical segment with an altitude between one-eighth and one-fourth of the length of its base chord and has an external marginal flange. The curvature of the shell may be sharper adjacent to its margin than at its center. The shell may include a vent aperture to drain condensate liquid from the interior of the streetlight.
