    Abstract: A decorative illumination setup designed to be used on wall surfaces of a room includes two background boards at different angles to a surface glass plate so as to create a three dimensional impression. A silhouetted picture is fitted in front of the background boards and an illumination apparatus is placed behind the silhouette. The illumination apparatus directs light onto the background boards from where the light is reflected into the room. Scenery may be placed on the background boards and/or the surface plate. The silhouetted picture is seen from the room as a silhouette with light passing through its outlines and openings.
