Abstract
A lamp assembly includes a light source, a lamp shade arranged to transmit light from the light source, and a casing arranged to accommodate the lamp shade, the casing and lamp shade substantially surrounding the light source. Although arranged to appear opaque when the light source is not illuminated, the casing is arranged to at least partially transmit light upon illumination of the light source so as to reduce shadows that would otherwise be cast by the casing.
