Abstract

L'addition concerne notamment l'extension à divers appareils tels qu'appareils de signalisation de circulation tableaux de bord ou de commande, récepteurs de télévision, du dispositif anti-éblouissant selon le brevet principal consistant en ce que l'objectif tel que le tube cathodique 15 G est placé dans un renoncement 11 G du boîtier du coffret 10 G et incliné d'un angle tel que les réflexions de la lumière ambiante par l'objectif ne sont pas renvoyées à l'observateur; elle concerne en outre une disposition relative des fenêtres transparentes spéculaires et des tableaux lumineux appropriés pour empêcher les réflexions de la lumière ambiante vers l'observateur.The addition relates in particular to the extension to various devices such as traffic signaling devices, dashboards or control panels, television receivers, of the anti-glare device according to the main patent consisting in that the lens such as the tube cathode 15 G is placed in a recess 11 G of the housing of the cabinet 10 G and tilted at an angle such that reflections of ambient light by the objective are not returned to the observer; it further relates to a relative arrangement of the specular transparent windows and appropriate light boards to prevent reflections of ambient light towards the viewer.
