Abstract

L’invention concerne une pièce optique avec une portion de guidage (10) de la lumière par réflexion interne totale et comprenant: - un dioptre d'entrée (2), - une surface de renvoi (4), - un bord de coupure (6), - une première surface de réflexion (11) en aval du bord de coupure, - une deuxième surface de réflexion (21), - un dioptre de sortie (9) qui image une ligne de foyers agencée sur le bord de coupure (6),la surface de renvoi renvoyant les rayons lumineux (r1, r2) entrant vers la ligne de foyers,des premiers rayons (r1) passent à côté du bord de coupure (6) et atteignent ladite première surface de réflexion (11), ladite première surface de réflexion réfléchissant ces premiers rayons vers ladite deuxième surface de réflexion (21), qui les réfléchit ensuite vers le dioptre de sortie (9).
