Abstract

An optical system includes optical fibers, a decoupling surface, an intersecting surface and a connecting portion. The optical fibers are arranged in at least one row. Each of the optical fibers includes a coupling surface onto which light from a light source is received. Light is directed through the optical fibers along an optical main axis. Light emitted from the optical fibers is directed onto a decoupling surface. The connecting portion is planar and is disposed between the decoupling surface and the optical fibers. The intersecting surface bounds the decoupling surface and is parallel to the optical main axis. Each of the optical fibers has an intersecting face oriented parallel to the optical main axis and parallel to the intersecting surface. The intersecting surface and the intersecting faces of the optical fibers generate a sharp outer edge of a light pattern formed by light emitted from the optical system.
