  • Publication number: 20220282846
    Abstract: A system includes a first primary optics that receives light from a first light source and projects it onto a transparent shutter and a secondary optics. A second primary optics receives light from the second light source and projects it onto the transparent shutter. The transparent shutter receives light from the first light source via the first primary optics and prevents a lower part of it from entering the secondary optics. The transparent shutter further receives light from the second light source via the second primary optics and projects it onto the secondary optics. The secondary optics receives light from the first primary optics and the transparent shutter and projects it onto a road in front of the vehicle. The transparent shutter includes an air-exposed slit that redirects the light received by the transparent shutter from the second light source toward a middle axis of the transparent shutter.
