Abstract

L’invention concerne un dispositif de signalisation lumineux offrant des effets dynamiques originaux. Selon l’invention, le dispositif de signalisation lumineux (2) comprend une source lumineuse (4) pilotée par une unité de commande (10). Un guide de lumière (14) est éclairé par la source lumineuse (4). Le guide de lumière (12) comprend un chanfrein (24) permettant au faisceau lumineux (8) émis par la source de lumière d’éclairer une zone A, au moins dix fois plus intensément qu’une zone B éclairée par des éléments diffusants (26) présents dans le guide de lumière. Les zones A et B sont présentes au niveau d’une face avant (20) du guide de lumière. L’unité de commande (10) est configurée pour faire varier l’intensité lumineuse du faisceau lumineux (8) émis par la source lumineuse (4) de manière à créer des effets dynamiques originaux au niveau des zones A et B. Figure 1The invention relates to a luminous signaling device offering original dynamic effects. According to the invention, the light signaling device (2) comprises a light source (4) controlled by a control unit (10). A light guide (14) is illuminated by the light source (4). The light guide (12) comprises a chamfer (24) allowing the light beam (8) emitted by the light source to illuminate an area A, at least ten times more intensely than an area B illuminated by diffusing elements ( 26) present in the light guide. Zones A and B are present at a front face (20) of the light guide. The control unit (10) is configured to vary the light intensity of the light beam (8) emitted by the light source (4) so as to create original dynamic effects in zones A and B. Figure 1
