Abstract
A commercial refrigerator cabinet is illuminated by fluorescent lamps which are located closely behind insulated glass doors for closing the cabinet. Each lamp is located behind a reflector and is at least partially enclosed by a clear plastic lens having multiple facets on its inner side. The reflector and the lens cause the light emitted from the lamp to reflect and refract in such a manner as to distribute the light substantially uniformly on products located at various distances from the lamp and to reduce glare in the immediate vicinity of the lamp.
