Abstract

Titre de l’invention : Bloc optique d’un module d’éclairage et de signalisation lumineuse La présente invention concerne un bloc optique (1) d’un module d’éclairage et de signalisation lumineuse de véhicule, destinée à être traversée par des rayons lumineux, comprenant une première portion (6) dédiée à une première fonction lumineuse et une deuxième portion (8) dédiée à une deuxième fonction lumineuse, différente de la première fonction lumineuse. Selon l’invention, le bloc optique (1) comporte des éléments de support (36, 36A, 36B) qui relient la première portion (6) et la deuxième portion (8), une fenêtre (38) s’étendant entre les éléments de support (36, 36A, 36B). Figure de l’abrégé : Figure 1Title of the invention: Optical unit of a lighting and light signaling module The present invention relates to an optical unit (1) of a vehicle lighting and light signaling module, intended to be traversed by light rays, comprising a first portion (6) dedicated to a first light function and a second portion (8) dedicated to a second light function, different from the first light function. According to the invention, the optical unit (1) comprises support elements (36, 36A, 36B) which connect the first portion (6) and the second portion (8), a window (38) extending between the support elements (36, 36A, 36B).
