CA 2333500

The invention relates to an illuminated indication device for road traffic. A number of indicating points are formed with indicating lenses (1) in or on an indicating surface. Said indicating lenses have a light entry surface (9) and a light exit surface (8) and are illuminated by the rear face of the indicating surface, which consists of individually allocated light-emitting elements with a small diameter. The aim of the invention is to make the indication device easier to read. To this end, the light entry surface (9) and/or the light exit surface (8) is/are shaped in such a way that the distribution of light intensity on the indicator surface extends further in a horizontal direction than in a vertical direction.

L'invention concerne un système de signalisation lumineuse pour la circulation routière, selon lequel une pluralité de points d'affichage sont formés dans ou sur une surface d'affichage, avec des lentilles d'affichage présentant une surface d'entrée de la lumière (9) et une surface de sortie de la lumière (8), lesdites lentilles d'affichage étant éclairées depuis la face arrière de la surface d'affichage à l'aide, dans chaque cas, d'éléments lumineux correspondants, de diamètre plus réduit. On parvient à une meilleure lisibilité de l'affichage, du fait que la surface d'entrée de la lumière (9) et/ou la surface de sortie de la lumière (8) est/sont formée(s) de manière que la répartition de l'intensité lumineuse sur la face d'affichage présente une plus forte extension dans le sens horizontal que dans le sens vertical.
