ABSTRACT The illuminated board consists of a rectangular transparent wedge-formed slab which at one face is covered by an opalescent front panel and at the other face by a reflecting, preferably white, rear panel. When the broad end face on the wedge is illuminated all light will, in an evenly distributed fashion, be directed to the front panel which has a low degree of opalescence and therefore presents itself as a brilliantly illuminated surface. The construction makes for a lower energy consumption and a less bulky construction than coventional illuminated boards used as sign boards and as illuminated tables in the graphic industries and in draftsmen's offices.
