Abstract

Various implementations of an illumination system include a light guide, a housing having a ceiling and defining a window, and a base coupled to the housing. The light guide is supported between the base and the ceiling. At least one light source is disposed adjacent a first end of the light guide. The light guide transmits the light from the light source through at least a portion of the outer surface of the light guide and the window. One or more tabs extending from the base each define at least one opening, and the at least one opening defined by each tab is alignable with an opening in a spoke portion of a frame. The openings receive a fastener to couple the base to the spoke portion. The housing may be integrally formed with a trim cover coupled to the frame.

First claim

What is claimed is:

1. An illumination system within a vehicle, the illumination system comprising:
a light guide having an outer surface and an inner surface that extend between a first end and a second end of the light guide;
a visible light source disposed adjacent the first end of the light guide, the visible light source emitting visible light into the first end of the light guide;
an infrared light source disposed adjacent the inner surface of the light guide, the infrared light source emitting infrared light into the inner surface of the light guide; and
a lens having an inner surface and an outer surface, the inner surface of the lens being disposed adjacent the outer surface of the light guide;
wherein the light guide transmits visible light from the visible light source and infrared light from the infrared light source through at least a portion of the outer surface of the light guide, and the visible light and the infrared light from the outer surface of the light guide passes through the lens, and
wherein the illumination system is coupled to a rim of a steering assembly, and the light guide and the lens have an arcuate shape corresponding to a radius of curvature of the rim of the steering assembly.

2. The illumination system of claim 1 , wherein the visible light source is a visible light emitting diode (LED).

3. The illumination system of claim 1 , wherein the visible light source comprises a first visible light source adjacent the first end of the light guide and a second visible light source adjacent the second end of the light guide.

4. The illumination system of claim 3 , wherein the first visible light source emits a first color of light and the second visible light source emits a second color of light.

5. The illumination system of claim 4 , wherein the first color and the second color are the same.

6. The illumination system of claim 4 , wherein the first color and the second color are different.

7. The illumination system of claim 3 , wherein the infrared light source comprises a first infrared light source adjacent the inner surface of the light guide adjacent the first end of the light guide and a second infrared light source adjacent the inner surface of the light guide adjacent the second end of the light guide.

8. The illumination system of claim 7 , wherein the outer surface of the lens comprises an opaque cover defining a transparent and/or translucent portion.

9. The illumination system of claim 8 , wherein the visible light from the first visible light source and the second visible light source passes through the transparent and/or translucent portion of the opaque cover.

10. The illumination system of claim 9 , wherein the outer surface of the lens further comprises a first infrared transmissive portion and a second infrared transmissive portion, wherein infrared light from the first infrared light source passes through the first infrared transmissive portion and infrared light from the second infrared light source passes through the second infrared transmissive portion.

11. The illumination system of claim 1 , wherein the outer surface and the inner surface of the light guide are arcuate-shaped between the first end and the second end of the light guide and are spaced apart and opposite each other relative to a plane that extends through the first end and the second end of the light guide and is parallel to the outer surface and the inner surface of the light guide.

12. The illumination system of claim 1 , wherein the infrared light source is an infrared light emitting diode (LED).

13. The illumination system of claim 1 , wherein the outer surface of the lens comprises an opaque cover defining a transparent and/or translucent portion.

14. The illumination system of claim 13 , wherein the visible light from the visible light source passes through the transparent and/or translucent portion of the opaque cover.

15. The illumination system of claim 14 , wherein the outer surface of the lens further comprises an infrared transmissive portion, wherein infrared light from the infrared light source passes through the infrared transmissive portion.

16. The illumination system of claim 1 , wherein the infrared light source comprises a first infrared light source adjacent the inner surface of the light guide adjacent the first end of the light guide and a second infrared light source adjacent the inner surface of the light guide adjacent the second end of the light guide.

17. The illumination system of claim 16 , wherein the outer surface of the lens further comprises a first infrared transmissive portion adjacent the first end of the light guide and a second infrared transmissive portion adjacent the second end of the light guide.

18. The illumination system of claim 1 , wherein the lens comprises micro-lenses.

19. The illumination system of claim 18 , wherein a density of the micro-lenses increases as a distance from the visible light source increases.
