Lighting device e.g. navigation light, for use in headlamp of e.g. motor vehicle, has reflector formed such that ring-shaped focal line is formed in area of ring-shaped light-injecting surface for injecting light beam into injecting surface

摘要

The device has a light guiding device (3) transferring a light beam (6) to a downstream light-decoupling device,. The light-guiding device has a funnel-shaped light guiding unit (8), which is tapered in a main direction of emission (2). An edge-sided front surface of the light-guiding device facing a reflector (5) forms a ring-shaped light-injecting surface. The reflector is formed such that a ring-shaped focal line (7) is formed in an area of the ring-shaped light-injecting surface for injecting the light beam into the injecting surface.
