Abstract

La présente invention concerne un projecteur (10) pour véhicule automobile, comprenant une source lumineuse (16), un réflecteur (14) du type elliptique dont un premier foyer est situé au voisinage de la source (16), une lentille convergente (18) dont un plan focal passe au voisinage d'un second foyer du réflecteur (14), un premier (24) et un deuxième (26) caches qui sont intercalés axialement, suivant l'axe optique (A-A) du projecteur (10), entre le réflecteur (14) et la lentille (18), du type dans lequel le premier cache (24) est monté pivotant autour d'un axe (A1) sensiblement transversal entre deux positions extrêmes.The present invention relates to a projector (10) for a motor vehicle, comprising a light source (16), a reflector (14) of the elliptical type of which a first focus is located in the vicinity of the source (16), a converging lens (18) a focal plane passes in the vicinity of a second focus of the reflector (14), a first (24) and a second (26) covers which are interposed axially, along the optical axis (AA) of the projector (10), between the reflector (14) and the lens (18), of the type in which the first cover (24) is pivotally mounted about an axis (A1) substantially transverse between two extreme positions.

Selon la présente invention, le second cache (26) est monté à pivotement autour d'un second axe de pivotement (A2) agencé sur le premier cache (24), le premier cache (24) est globalement rectangulaire, et le second axe de pivotement (A2) est agencé le long du bord transversal supérieur du premier cache (24).

Figure imgaf001
According to the present invention, the second cover (26) is pivotally mounted about a second pivot axis (A2) arranged on the first cover (24), the first cover (24) is generally rectangular, and the second cover is pivoting (A2) is arranged along the upper transverse edge of the first cover (24).
