Title
(EN) DEVICE FOR SIMULTANEOUSLY PROJECTING IMAGES AND ILLUMINATING THE AMBIENT
(FR) DISPOSITIF PERMETTANT SIMULTANEMENT DE PROJETER DES IMAGES ET D'EMETTRE UNE LUMIERE D'AMBIANCE
Abstract
(EN) A device (1) for projecting images (2) onto a projection surface (3), having an electro-optical arrangement (29) for generating and emitting light on the basis of image data, and having an optical system (9) for directing the light onto the projection surface (3), which optical system (9) has a movable redirecting mechanism (8') for the light, which redirecting mechanism (8') includes a redirecting part (8a) for the image projection and a separate light­transmitting part (8b) for selective ambience light projection.
(FR) Dispositif (1) de projection d'images (2) sur une surface de projection (3), présentant un agencement électro-optique (29) destiné à générer et à émettre de la lumière en fonction de données d'image, ainsi qu'un système optique (9) pour diriger la lumière sur la surface de projection (3). Ce système optique (9) comprend un mécanisme mobile de réorientation (8') de la lumière, doté d'une partie de réorientation (8a) destinée à la projection d'images et d'une partie d'émission de lumière séparée (8b) destinée à la projection sélective d'une lumière d'ambiance.
