Abstract

L'invention concerne les blocs optiques pour véhicules automobiles. Elle propose un bloc optique à contour d'ouverture non circulaire, caractérisé : a. par un réflecteur limité à la surface parabolique optiquement utile correspondant au contour d'ouverture choisi, b. par une glace de forme enveloppante comportant une face frontale et des parties de raccordement réunissant la face frontale au bord externe du réflecteur. Avantages de fabrication et de constitution.
