Abstract

L’invention concerne un dispositif lumineux (1) d’un véhicule automobile, comportant une source de lumière (2) et un collimateur (4), le collimateur comportant une portion centrale (7) entourée par une portion périphérique (8), la portion centrale comprenant une lentille (72) comportant une surface d’entrée (71) et une surface de sortie (73), caractérisé en ce que la surface d’entrée est agencée pour que le cône de lumière (C1) émis par la source de lumière et capté par l’intégralité de la surface d’entrée soit dévié par la surface d’entrée sur l’intégralité de la surface de sortie, la surface de sortie étant plus grande que la surface d’entrée et la surface de sortie étant agencée pour collimater ledit cône de lumière dévié par la surface d’entrée. Figure pour l’abrégé : Fig. 2The invention relates to a light device (1) of a motor vehicle, comprising a light source (2) and a collimator (4), the collimator comprising a central portion (7) surrounded by a peripheral portion (8), the central portion comprising a lens (72) having an entrance surface (71) and an exit surface (73), characterized in that the entrance surface is arranged so that the light cone (C1) emitted by the source of light and captured by the entire entrance surface is deflected by the entrance surface over the entire exit surface, the exit surface being larger than the entrance surface and the exit surface being arranged to collimate said cone of light deflected by the entrance surface.
