Abstract

L’invention concerne un dispositif lumineux (1) pour véhicule (2) comprenant un générateur de lumière (10) transparent avec une face avant (10.1) et configuré pour générer un faisceau lumineux (Lx), caractérisé en ce qu’il  comprend en outre :- une pièce opaque (11) disposée directement en regard de la face arrière (10.2) dudit générateur de lumière (10) de sorte à être visible à travers lui, la pièce opaque (11) présentant sur une face (11.1) orientée vers ledit générateur de lumière (10) une première couleur (c1), et- une pièce extérieure (12) comprenant une portion transparente (12.a) disposée en regard de ladite pièce opaque (11) et configurée pour laisser sortir du dispositif lumineux (1) ledit faisceau lumineux (Lx) généré par ledit générateur de lumière (10), et comprenant une autre portion (12.b) différente de ladite portion transparente (12.a) et présentant une deuxième couleur (c2) similaire à ladite première couleur (c1). Figure pour l’abrégé: figure 1The invention relates to a light device (1) for a vehicle (2) comprising: a transparent light generator (10) with a front face (10.1) and configured to generate a light beam (Lx), characterized in that it: comprises in in addition:- an opaque part (11) placed directly opposite the rear face (10.2) of said light generator (10) so as to be visible through it, the opaque part (11) having on one face (11.1) oriented towards said light generator (10) a first color (c1), and - an external part (12) comprising a transparent portion (12.a) placed opposite said opaque part (11) and configured to let out of the light device (1) said light beam (Lx) generated by said light generator (10), and comprising another portion (12.b) different from said transparent portion (12.a) and having a second color (c2) similar to said first color (c1).
