Abstract

Titre : Module lumineux pour dispositif d’éclairage et/ou de signalisation La présente invention concerne un module lumineux (2) comprenant au moins une source lumineuse (3) et un écran (5) au moins partiellement transparent, l’écran (5) présentant une première face (53) et une deuxième face (54) opposée et définissant entre elles l’épaisseur de l’écran bi-matière (5), la source lumineuse (3) étant configurée pour émettre une pluralité de rayons lumineux (9) au sein de l’écran (5) selon une première direction d’émission principale sensiblement parallèle aux faces (53, 54) de l’écran, caractérisé en ce que l’écran (5) est un écran bi-matière comprenant deux matériaux dont les taux de voile sont différents et parmi lesquels un premier matériau (6), présentant un premier taux de voile et formant un matériau de base de l’écran, et un deuxième matériau (7), présentant un deuxième taux de voile supérieur au premier taux de voile et disposé partiellement dans l’épaisseur de l’écran bi-matière (5), le deuxième matériau (7) étant configuré pour dévier les rayons lumineux selon une deuxième direction d’émission en direction de la première face (53) ou de la deuxième face (54). L’invention couvre également un dispositif d’éclairage et/ou de signalisation comprenant un tel module lumineux (2). Figure pour l’abrégé : Fig 2Title: Light module for lighting and/or signaling device The present invention relates to a light module (2) comprising at least one light source (3) and an at least partially transparent screen (5), the screen (5) having a first face (53) and a second opposite face (54) and defining between them the thickness of the bi-material screen (5), the light source (3) being configured to emit a plurality of light rays (9 ) within the screen (5) along a first main emission direction substantially parallel to the faces (53, 54) of the screen, characterized in that the screen (5) is a bi-material screen comprising two materials whose haze rates are different and among which a first material (6), having a first haze rate and forming a base material of the screen, and a second material (7), having a second higher haze rate at the first rate of haze and placed partially in the thickness of the bi-material screen (5), the second material (7) being configured to deflect the light rays in a second direction of emission towards the first face (53) or the second face (54). The invention also covers a lighting and/or signaling device comprising such a light module (2). Figure for abstract: Fig 2
