Abstract
A sign apparatus includes a sign cabinet with a window (4) inclined towards the observation plane. Inside the window, which is a color filter, there is arranged a panel (5) with electrically driven character elements (7). The angle of inclination (.beta.) of the panel is equal to, or less than, the angle of inclination (.alpha.) of the window. Each character element is formed by obliquely disposed rows of light emitting diodes.
Claims6
Sign apparatus intended for text and/or numerical display outdoors and including electrically driven character elements (7) each comprising rows of LED's defining a dot raster surface disposed on a panel (5), the former being illuminable and extinguishable from a remotely placed operating unit, and grouped such that different illuminated combinations form different characters, characterized in that the panel (5) is mounted inside a sign cabinet formed with a roof (1), intended for erection at a relatively great height above the observation plane where the observer stands, and has a window (4) comprising a color filter at a distance in front of the panel (5), said window (4) being disposed at a predetermined angle (.alpha.) of approximately twenty to thirty degrees to the vertical, so that the surface of the window is inclined towards the observation plane, the panel (5) being disposed inside the window at an angle (.beta.) of approximately fifteen degrees to the vertical and being mounted for pivotal movement to adjust said angle of inclination (.beta.).
