Flat light device, e.g. illuminated advertising panel, has light output coupling points on side of light conducting panel facing away from observer, forming sub-areas of light conducting panel

摘要

The device has a light conducting panel (3) with a number of light output coupling points, a light source parallel to the edge of the panel and preferably a diffusing panel at a distance from the light conducting panel. The output coupling points are arranged on the side of the light conducting panel facing away from the observer and form sub-areas (4) of the light conducting panel.
