Abstract
The present invention concerns a lighting device for an automobile, comprising a light source situated at the first focus of a reflector of the elliptical type, a convergent lens being disposed in front of the light source so that the second focus of the elliptical reflector is contained in the object focal plane of the convergent lens, the first and second foci of the elliptical reflector defining an optical axis of the lighting device. According to the present invention, an obscuring element is disposed substantially perpendicular to the optical axis and at a distance from the object focal plane of the convergent lens.
