Abstract
L'invention concerne une optique de collimation (10) comprenant un corps (100) en matériau transparent comportant au moins une cavité (101) recevant une diode électroluminescente (11) et définie par une surface centrale (102) et une surface latérale (103), une surface de réflexion interne totale (104) entourant chaque cavité et une surface de sortie (105). La surface de réflexion interne totale réfléchit totalement les rayons lumineux réfractés à l’intérieur du corps par les surfaces centrale et latérale de la cavité et les dirige vers la surface de sortie parallèlement à une direction de collimation. La surface de sortie (105) présente au moins une zone de diffraction texturée (106) dans son épaisseur dont la géométrie est conformée de sorte que les rayons lumineux réfractés à l’intérieur du corps par la cavité sont diffractés à l’extérieur du corps par la zone de diffraction texturée suivant un faisceau lumineux présentant une photométrie et une forme déterminées.
