Abstract

L'invention concerne une lentille optique pour dispositif d'éclairage notamment de véhicule automobile, comportant un dioptre d'entrée et un dioptre de sortie et configurée pour permettre l'émission d'un faisceau lumineux de sortie suivant un axe optique par le dioptre de sortie à réception d'un flux lumineux d'entrée par le dioptre d'entrée, le dioptre de sortie présentant un profil convexe suivant un premier plan parallèle à l'axe optique, caractérisée en ce que le profil convexe est une portion d'une pseudo-ellipse ayant un grand axe parallèle à l'axe optique (7) et un petit axe (16) sécant avec le grand axe, la pseudo ellipse différant d'une ellipse au moins en ce que ledit grand axe coupe ledit petit axe en un point différent du milieu du petit axe (16).The invention relates to an optical lens for a lighting device, in particular a motor vehicle, comprising an input diopter and an output diopter and configured to allow the emission of an output light beam along an optical axis through the diopter of output on reception of an input luminous flux by the input diopter, the output diopter having a convex profile in a first plane parallel to the optical axis, characterized in that the convex profile is a portion of a pseudo-ellipse having a major axis parallel to the optical axis (7) and a minor axis (16) intersecting with the major axis, the pseudo-ellipse differing by at least one ellipse in that said major axis intersects said minor axis by a different point of the middle of the minor axis (16).
