Abstract
A space at least partly enclosed by an appliance housing can be illuminated by utilizing at least one lamp outside that space and coupling a light pipe system to that lamp so that light can be conducted into the space by a light-transmission system. Within the space light is emitted from one or more light extractors optically coupled to the light-transmission system. The light extractors are in the form of wave guides provided along a surface with formations or the like from which light is emitted.
