The invention relates to an optical glare limiter (16) which uses an electrical power source and which can, in particular, be used in motor vehicles. Said optical glare limiter is comprised of a light receiver module (4) and of a light source (2). The incident luminous radiation of the light source of the glare limiter on a reflective surface can be regulated according to the intensity of the incident luminous radiation of an external glare source (18) on the light receiver module. Said incident luminous radiation of the light source can be regulated by an electronic control device (6) in such a way that the light in the visual field of the vehicle driver has approximately homogeneous and wide area contrast ratios with a diminished glare effect.

L'invention concerne un limiteur d'éblouissement optique (16) qui fait appel à l'utilisation d'une source de courant et s'utilise notamment dans des automobiles. Ce limiteur d'éblouissement comprend un module récepteur de lumière (4) et une source de lumière (2). Le faisceau lumineux de la source de lumière du limiteur d'éblouissement qui arrive sur une surface réfléchissante peut être ajusté en fonction de l'intensité du faisceau lumineux qui arrive sur le module récepteur de lumière et provient d'une source d'éblouissement (18) extérieure, au moyen d'une commande (6) électronique, de manière que la lumière présente dans le champ de vision du conducteur des rapports de contraste approximativement homogènes et larges plats avec un effet éblouissant réduit.
