Abstract (en)
[origin: US2018119899A1] 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.
