Abstract

L'invention concerne un élément optique (1) monobloc comprenant une première extrémité (4) comportant une pluralité d'entrées de lumière (10) distinctes les unes des autres par lesquelles des rayons lumineux entrent dans l'élément optique (1), l'élément optique (1) comprenant une deuxième extrémité (5) par laquelle sortent de manière commune les rayons lumineux, la deuxième extrémité (5) étant configurée pour mettre en forme un faisceau lumineux externe à l'élément optique (1), l'élément optique (1) étant défini par un axe (O) passant au moins par la première extrémité (4) et par la deuxième extrémité (5), caractérisé en ce que l'élément optique (1) comprend au moins une première zone de contact (11) dédiée à son référencement mécanique le long de l'axe (O) et au moins une deuxième zone de contact (12) dédiée à son référencement mécanique le long d'une direction (D1) transversale à l'axe (O), la deuxième zone de contact (12) étant plus proche de la deuxième extrémité (5) que de la première extrémité (4).
