Abstract
The light source of an area light or streetlight mounted on a lamppost is enclosed by a lower upwardly flaring bowl having its upper end closed by a generally conical cap. The cap and bowl are made of polycarbonate pigmented by titanium dioxide so that the cap emits only light sufficient to enable its shape to be seen in darkness and the bowl is much more translucent to emit adequate light for illumination.
