Abstract

L'invention concerne un dispositif d'éclairage et/ou de signalisation, notamment de véhicule automobile, présentant un axe optique (Z-Z') et agencé pour produire :
- un premier faisceau élémentaire (20) présentant, sur un écran perpendiculaire à l'axe optique (Z-Z'), une coupure (21) comportant une première branche nette (21 B) et une seconde branche floue (21A), et
- un second faisceau élémentaire de préférence présentant, sur un écran perpendiculaire à l'axe optique (Z-Z'), une coupure,
caractérisé en ce que la branche floue (21A) de la coupure (21) du premier faisceau élémentaire (20) est au moins partiellement incluse dans le second faisceau élémentaire.

Figure imgaf001
The invention relates to a lighting and / or signaling device, in particular a motor vehicle, having an optical axis (Z-Z ') and arranged to produce:
a first elementary beam (20) having, on a screen perpendicular to the optical axis (Z-Z '), a cutoff (21) comprising a first net branch (21 B) and a second fuzzy branch (21A), and
a second elementary beam preferably having, on a screen perpendicular to the optical axis (Z-Z '), a cutoff,
characterized in that the fuzzy branch (21A) of the cutoff (21) of the first elementary beam (20) is at least partially included in the second elementary beam.
