Abstract: The invention relates to an optical module intended to project a final light beam having a profiled cutoff having at least one horizontal segment, including a controlled light source emitting an initial beam, and optical cutting-off means for converting the initial beam into an intermediate cutoff beam containing a cutoff, in which beam the light rays are distributed vertically below the profiled cutoff. The optical module includes horizontally focusing optical means for focusing the intermediate cutoff beam toward a substantially vertical line of focus, and an exit lens having a vertical focal line that is coincident with the line of focus in order to convert the intermediate cutoff beam into the final beam.

Abstract: The invention relates to a light-emitting module including a light source capable of emitting light rays, a collector with a reflective surface, an optical system configured to project a light beam by imaging a portion of the reflective surface located behind the light source, a screen located in front of the light source, with a rear face arranged so as to gather light rays which are emitted forward by the light source and are not reflected by the reflective surface. The screen includes an end face, adjacent to the rear face and facing the reflected light rays, which is configured to avoid and/or to absorb the reflected light rays.
