Abstract
A recessed exit sign includes an electrical component housing, a plaster ring, and an illuminated message panel. The lighting assembly includes an electrical component assembly, an internal power source housed within the electrical component assembly, a light source housed within the electrical component assembly, and a lens. The power source is electrically coupled to the light source. A portion of the lens is inserted into an opening formed within the electrical component assembly and coupled to the electrical component assembly. The lens extends from within the electrical component assembly to a location outside the electrical component assembly. A portion of the lighting assembly is slidably inserted through the plaster ring and into the electrical component housing. When plaster is applied over the plaster ring the lens appears to simply enter a hole in the ceiling with not additional features visible on the ceiling surface to cause a distraction.
