CA 2254546
In order to make traffic signs, information signs or advertising signs sufficiently visible in poor lighting conditions, a self-illuminated system with a fiber optic lighting device is provided. The signs and billboards to be illuminated include one or more preferably plastic panels functioning as a display device arranged over each other, in which light is propagated from the fiber-optic device parallel to a display plane. Transparent information or signaling entities are provided on or in the panel or panels. In order to improve the quality of the illumination and to lower the manufacturing costs, the fiber-optic device is assembled in a modular manner from a plurality of standardized parts for standard fiber-optic systems according to display system requirements and includes multi-arm light guides, light outlet bodies for the multi-arm light guides acting as optical attachments for adjusting propagation angles for the light so that light intensities over the entire angular range are uniform.
