Abstract

A front-lighting system for a vehicle has: a first light source, a second light source, a first primary optics, a second primary optics, a transparent shutter, and a secondary optics. The first primary optics receives light from the first light source and projects it onto the transparent shutter and the secondary optics. The 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 primary optics and prevents a lower part of it from entering the secondary optics, receives light from the second primary optics and projects it onto the secondary optics, and has a light out-coupling surface and micro-optical structures on a bordering surface. 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.
