Abstract

A lighting device (10) for a vehicle comprising: an array of optical fibers (28), at least a portion of said array of optical fibers being arranged in at least one predetermined form (32); at least one light source (20) for generating light to be transmitted through said array of optical fibers (28); and at least one support or frame (16) comprising a receiving area adapted to receive said at least one predetermined form; said at least one support or frame (16) being adapted for use on the vehicle to provide a lighting function on the vehicle. Furthermore, a lighting device (10) for a vehicle comprising: a housing (12); a plurality of support frames (16) located in said housing (12); and a plurality of fiber optic light panels (32) received in one of said plurality of support frames (16), each of said plurality of fiber optic light panels (32) comprising a plurality of optical fibers (28); said plurality of fiber optic panels (32) being adapted to receive light from at least one light source (20) to perform at least one lighting function.

Claims

1. A lighting device for a vehicle comprising:

a housing;

an array of optical fibers, at least a portion of said array of optical fibers being arranged in at least one predetermined form;

at least one light source to generate light to be transmitted through said array of optical fibers; and

at least one support or frame disposed within said housing, said at least one support or frame comprising a receiving area to receive said at least one predetermined form, and said at least one support or frame providing a lighting function on the vehicle, wherein

said housing further comprises a surface that includes a conduit that defines a passageway to receive said array of optical fibers, and

said at least one predetermined form includes at least one panel, said at least one support or frame defines a frame that includes an aperture, and said at least one panel is received in and framed by said frame such that light from said at least one panel passes through said aperture.

2. The lighting device as recited in claim 1, wherein said lighting device comprises at least one of optics or a mask situated in said at least one support or frame in operative relationship with said predetermined form in order to create a desired light pattern.

3. The lighting device as recited in claim 2, wherein said at least one of optics or said mask comprises at least one lens situated in operative relationship with said at least a portion of said array of optical fibers in order to generate said desired light pattern.

4. The lighting device as recited in claim 1, wherein said aperture is disposed on an outermost face of said frame relative to said vehicle.

5. The lighting device as recited in claim 1, wherein said lighting device comprises a driver to drive said at least one panel from a first position to a second position.

6. The lighting device as recited in claim 1, wherein said array of optical fibers defines a plurality of panels to be received and supported in said at least one support or frame, said plurality of panels cooperating to generate a desired visual effect.

7. The lighting device as recited in claim 6, wherein said lighting device comprises a plurality of light sources associated with said plurality of panels, respectively, said plurality of panels being arranged such that said lighting device performs a plurality of different light functions.

8. The lighting device as recited in claim 7, wherein said plurality of different light functions comprises at least one of a stop light function, a park light function, a daytime running light function, a tail light function or a turn signal function.

9. The lighting device as recited in claim 8, wherein said plurality of different light functions comprises different colors that include at least one of amber or red.

10. The lighting device as recited in claim 1, wherein said at least one light source generates a plurality of different colors, and said at least one light source is under control of a controller so that said at least one panel emits light of different colors to perform different lighting functions.

11. A lighting device for a vehicle comprising:

a housing;

a plurality of support frames located in said housing; and

a plurality of fiber optic light panels received in said plurality of support frames, each of said plurality of fiber optic light panels comprising a plurality of optical fibers, and said plurality of fiber optic panels to receive light from at least one light source to perform at least one lighting function, wherein

each of said plurality of support frames receives a different fiber optic light panel of said plurality of fiber optic light panels, and

each of said plurality of support frames receives more than one of said plurality of fiber optic light panels.

12. The lighting device as recited in claim 11, wherein each of said plurality of support frames comprises a plurality of frame walls that are fastened together to house at least one of said plurality of optic light panels.

13. The lighting device as recited in claim 11, wherein lighting device further comprises at least one of a mask or optics placed in or on one of said plurality of support frames in operative relationship with respect to at least one of said plurality of fiber optic panels.

14. The lighting device as recited in claim 11, wherein each of said plurality of fiber optic light panels has at least one light source associated therewith.

15. The lighting device as recited in claim 11, wherein said plurality of fiber optic panels comprises at least a first panel and a second panel, at least one of said plurality of support frames comprises a first aperture and a second aperture to house both said first panel and said second panel back-to-back so that light from said first panel is emittable through said first aperture and light from said second panel is emittable through said second aperture.

16. The lighting device as recited in claim 15, wherein said at least one lighting function comprises a first light function and a second light function and wherein the light from the first panel is of a first color to perform said first light function and light from said second panel is of a second color to perform said second light function which is different from said first light function.

17. The lighting device as recited in claim 16, wherein said first light function comprises:

a stop light function, a turn signal function, a daytime running light function, a headlamp function or a tail lamp function,

said second light function is a different one of said stop light function, turn signal function, daytime running light function, headlamp function or tail lamp function.

18. The lighting device as recited in claim 11, wherein said lighting device further comprises a plurality of couplers associated with a plurality of lighting devices, respectively, each of said plurality of couplers comprising:

a coupling sleeve to receive a bundle of said plurality of optical fibers; and

a light guide coupled to said coupling sleeve to guide light from at least one of said plurality of light sources to said bundle of said plurality of optical fibers.
