  • Patent number: 9879836
    Abstract: The present invention is directed toward a lighting device in a motor vehicle that includes a first light conductor and at least one second light conductor. The first light conductor propagates light by total internal reflection which impacts on a light coupling-out area of light conductor and is at least partially reflected toward and emits from an opposite light output area.

Light is coupled such that it has a lower divergence in the second layers than in the first layers. There is a first deflection area between the input coupler and the light emitting area, which redirects light emitted from the input coupler incident on it in an angle bigger than the double of the critical angle of the total internal reflection. Further deflection areas are illuminated with light emitted from the first deflection area and direct the incident light into a preferred common direction for the further deflection areas.
