Abstract
An edgelit illuminated display system has a transparent medium having first and second opposing surfaces and at least one edge operable with a light source for illuminating the first and second surfaces. A matrix of dots on each of the surfaces is arranged to allow interaction of light between the surfaces. The matrix of dots on at least one of the surfaces substantially covers the entire surface for providing an even increased illumination throughout the surface, wherein when a graphic image is supported over the surface the graphic image is evenly illuminated.
Claims2
An edgelit luminaire comprising:
- a housing having an opening, a display panel having an upper edge and at least one surface carrying a layer having sections of differing transparency forming a graphic symbol, a source of illumination arranged in the housing and located substantially adjacent to the upper edge of said display panel, said display panel attached to the housing such that the panel extends from the opening in the housing and an array of dots on substantially the entire said one surface including said layer of differing transparency, said array of dots having a luminous quality affected by said source of illumination to spread light throughout the entire surface of said display panel thereby greatly enhancing illumination of said graphic symbol.
An edgelit luminaire comprising:
- a housing having an opening, a display panel having an upper edge;
- a source of illumination arranged adjacent to the upper edge of said display panel;
- and a graphic symbol, said display panel attached to the housing such that the panel extends from the opening therein, the display panel consists of two sheets of transparent material of substantially identical dimensions, each of said sheets carries an array of luminous dots on one surface and at least one of said sheets carries said graphic symbol, said array of luminous dots being on substantially the entire panel surface including the graphic symbol for ensuring an even distribution of light throughout the entire surface of the panel.
