Abstract

An illumination device for producing a light strip along a predetermined distance includes light sources and light conductors, wherein light of a first one of the light sources is distributable along a first section of the distance by a first one of the light conductors up to an end region of the first light conductor, wherein light of a second one of the light sources is distributable along a second section of the distance by a second one of the light conductors up to an end region of the second light conductor, and wherein the end region of the first light conductor and the end region of the second light conductor are arranged adjacent one another along the distance.

First claim

What is claimed is:

1. An illumination device for generating a light strip along a predetermined distance, comprising:
first and second light sources; and
first and second light conductors, wherein the first light source is arranged at a first light entry point of the first light conductor and the second light source is arranged at a second light entry point of the second light conductor, said first light conductor conducting light of the first light source from the first light entry point of the first light conductor to a terminus of the first light conductor opposite the first light entry point along a first section of the predetermined distance, said second light conductor conducting light of the second light source from the second light entry point of the second light conductor to a terminus of the second light conductor opposite the second light entry point along a second section of the distance, wherein the terminus of the first light conductor and the terminus of the second light conductor cross over along a course of the predetermined distance, and wherein the first and the second section are each defined by an axis and are arranged coaxial to each other.

2. The illumination device of claim 1 , wherein the terminus of the first light conductor and the terminus of the second light conductor are supported for movement relative to one another in a direction of extension of the predetermined distance.

3. The illumination device of claim 1 , wherein the first light source and the second light source are arranged in relation to the first and second light conductors so that light emitted by the first and second light sources is guided in the first and second light conductors in opposite directions along the predetermined distance.

4. The illumination device of claim 1 , further comprising an at least partially transparent receiving device extending along the first and second sections of the distance, wherein the first and second light conductors are arranged in the receiving device so as to be movable relative to the receiving device in a direction of extension of the predetermined distance.

5. The illumination device of claim 1 , wherein one of the first and second light conductors has a bent shape in a region of the terminus of the first light conductor or in a region of the terminus of the second light conductor.

6. The illumination device of claim 1 , wherein at least the first light conductor is configured in the shape of an L and having a coupling-in region arranged in a corner of the L for coupling the light of the first light source into the first light conductor.

7. The illumination device of claim 1 , further comprising a further light source arranged in relation to the first light conductor so that light emitted by the first light source is conducted in the first light conductor along a third section of the predetermined distance up to another terminus of the first light conductor.

8. A motor vehicle, comprising:
at least one illumination device for generating a light strip along a predetermined distance, said at least one illumination device comprising
first and second light sources; and
first and second light conductors, wherein the first light source is arranged at a first light entry point of the first light conductor and the second light source is arranged at a second light entry point of the second light conductor, said first light conductor conducting light of the first light source from the first light entry point of the first light conductor to a terminus of the first light conductor opposite the first light entry point along a first section of the predetermined distance, said second light conductor conducting light of the second light source from the second light entry point of the second light conductor to a terminus of the second light conductor opposite the second light entry point along a second section of the distance, and wherein the terminus of the first light conductor and the terminus of the second light conductor cross over along a course of the predetermined distance, and wherein the first and the second section are each defined by an axis and are arranged coaxial to each other.

9. The motor vehicle of claim 8 , wherein a closable opening is surrounded by the at least one illumination device.

10. The motor vehicle of claim 8 , further comprising a sunroof encased by an encasement, wherein the at least one illumination device is arranged in the encasement.

11. The motor vehicle of claim 8 , wherein the at least one illumination device further comprises multiple of said first and second light sources and multiple of said first and second light conductors, wherein the multiple first and second light sources are arranged in respective corner regions of the distance and the end regions of the multiple first and second light conductors are arranged in a straight section of the distance.
