Title (EN) LIGHTING AND/OR SIGNALLING DEVICE, IN PARTICULAR FOR AN AUTOMOTIVE VEHICLE
(FR) DISPOSITIF D'ÉCLAIRAGE ET/OU DE SIGNALISATION, NOTAMMENT POUR VÉHICULE AUTOMOBILE
Abstract:
(EN) The invention relates to a signalling and/or lighting device, in particular for an automotive vehicle, comprising: means for emitting a light beam, referred to as the primary beam (100), including a light source (1), a diffusion element (3) and controlled transmission means that are interposed between the emission means and the diffusion element (3), the controlled transmission means being controlled so as to selectively transmit at least a portion of the primary beam (100) in the direction of the diffusion element (3) in order to form a beam, referred to as the secondary beam (200), according to at least two different light distributions, characterized in that the controlled transmission means comprise at least one liquid-crystal screen (2) that is arranged at a distance from the diffusion element (3), an image of the liquid-crystal screen (2) being formed on the diffusion element (3). The invention also relates to a lighting module for an automotive vehicle comprising such a device.
(FR) L'invention concerne un dispositif de signalisation et/ou d'éclairage, notamment pour véhicule automobile, comprenant: des moyens d'émission d'un faisceau lumineux, dit faisceau primaire (100), comportant une source lumineuse (1), un élément de diffusion (3) et des moyens de transmission commandés interposés entre les moyens d'émission et l'élément de diffusion (3), les moyens de transmission commandés étant commandés pour transmettre sélectivement au moins une partie du faisceau primaire (100) vers l'élément de diffusion (3) afin de former un faisceau, dit faisceau secondaire (200), selon au moins deux distributions différentes de la lumière, caractérisé en ce que les moyens commandés de transmission comprennent au moins un écran à cristaux liquides (2) agencé à distance de l'élément de diffusion (3), une image de l'écran à cristaux liquides (2) étant formée sur l'élément de diffusion (3). L'invention concerne encore un module d'éclairage pour véhicule automobile comprenant un tel dispositif.
