The invention relates to optical displays containing one or more shaped bodies (41) and a light source (43). The shaped bodies (41) consist of a transparent or semi-transparent plastic. This plastic contains one or more fluorescent substances. One or more light sources (43) are arranged in such a way that their light is directed into the shaped body (41) in particular areas of its surface and transmitted in said shaped body. The shaped body contains means for coupling out the light in a specific manner so that the light is specifically coupled out of the shaped body (41) in very specific areas (45) of its surface.
L'invention concerne des indicateurs visuels contenant au moins un corps moulé (41) et une source lumineuse (43). Les corps moulés (41) sont composés d'une matière plastique transparente ou semitransparente. La matière plastique contient au moins une substance fluorescente. Au moins une source lumineuse (43) est placée de telle façon qu'au niveau de certaines zones superficielles du corps moulé (41), sa lumière entre dans ce corps moulé et soit réémise dans le corps moulé. Le corps moulé contient des moyens permettant le prélèvement ciblé de la lumière de telle façon que dans certaines zones (45) bien précises de la surface du corps moulé (41), la lumière soit prélevée de façon ciblée du corps moulé (41).
