Abstract

A light system for a vehicle is provided herein. The light system includes a trim member defining an aperture. A light guide is disposed within the aperture. The light guide has a proximal portion operably coupled with a light source. A lens is integrally formed with the light guide and is disposed at a distal portion of the light guide. A deformable attachment mechanism is integrally formed on the light guide between the proximal and the distal portions of the light guide. The light guide is compressively retained within the aperture by a forward portion of the attachment mechanism and a rearward portion of the lens.

First claim

What is claimed is:

1. A light system for a vehicle, comprising:
a trim member defining an aperture;
an optical fiber light guide disposed within the aperture, the optical fiber light guide having a proximal portion operably coupled with a light source;
a lens integrally formed with the optical fiber light guide and disposed at a distal portion of the optical fiber light guide; and
a deformable attachment mechanism integrally formed on a center axis of the optical fiber light guide between the proximal and the distal portions of the optical fiber light guide, wherein the optical fiber light guide is compressively retained within the aperture by a forward portion of the attachment mechanism on a first side of the trim member and a rearward portion of the lens on a second side of the trim member such that the lens and the attachment mechanism are spaced apart along the optical fiber light guide at a predefined distance, and wherein the deformable attachment mechanism defines an orifice on the center axis of the optical fiber light guide, the deformable attachment mechanism configured to deform into the orifice when the deformable attachment mechanism moves through the aperture.

2. The light system for a vehicle of claim 1 , wherein the optical fiber light guide is formed from a flexible material, and wherein the flexible material is silicone.

3. The light system for a vehicle of claim 1 , wherein the optical fiber light guide, the lens, and the attachment mechanism are all formed from a common material.

4. The light system for a vehicle of claim 3 , wherein the optical fiber light guide is integrally formed with the lens and attachment mechanism in a single manufacturing process.

5. The light system for a vehicle of claim 1 , wherein the trim member is disposed on a door panel within the vehicle and the predefined distance is equal to a thickness of the trim member.

6. The light system for a vehicle of claim 1 , wherein the lens is configured to direct light emitted by the light source within a void defined between an armrest and a door panel.

7. The light system for a vehicle of claim 1 , wherein a proximal portion of the optical fiber light guide is disposed within a light source housing and a distal portion of the optical fiber light guide terminates proximately to an A-surface of the trim member.

8. A light system, comprising:
a light guide configured as an optical fiber strand comprising a proximal portion configured to accept light emitted from a light source therethrough and a distal portion;
a lens integrally formed with the distal portion of the optical fiber strand and configured to output light emitted from the light source; and
an integrally formed deformable attachment mechanism formed on a center axis of the distal portion of the optical fiber strand and proximately disposed to the lens, wherein the light guide is maintained in a predefined position by the lens and attachment mechanism, the attachment mechanism comprising a rearward portion having a smaller diameter than a forward portion, wherein the light guide and the attachment mechanism are constructed of silicone.

9. The light system of claim 8 , wherein the light source is a laser diode optically coupled to the optical fiber strand.

10. The light system of claim 8 , wherein the light source is disposed within a light source housing.

11. The light system of claim 10 , wherein the light source housing includes a compression clip configured to maintain the housing in a substantially constant position and a light output window, and wherein the proximal portion of the light guide is disposed in the light output window.

12. The light system of claim 8 , wherein the lens comprises a concave lens structure.

13. The optical fiber light guide of claim 8 , wherein the deformable attachment mechanism defines an orifice on the center axis of the light guide, the deformable attachment mechanism configured to deform into the orifice as the light guide is inserted through an aperture of a trim panel.

14. An optical fiber light guide, comprising:
a proximal portion configured to accept light emitted from a light source therethrough;
a distal portion having an integrally formed lens configured to output light emitted from the light source; and
an integrally formed deformable attachment mechanism formed on a center axis of the distal portion disposed proximately to the lens, the deformable attachment mechanism defining an orifice on the center axis of said optical fiber light guide, the attachment mechanism configured to deform into the orifice, wherein the light guide, the lens, and the attachment mechanism are all formed from a silicone material, and wherein a rearward portion of the attachment mechanism has a smaller diameter than a forward portion of the attachment mechanism and a larger diameter than the distal portion.

15. The optical fiber light guide of claim 14 , wherein the light guide is configured to be inserted through an aperture defined by a trim member of a vehicle.

16. The optical fiber light guide of claim 15 , wherein the attachment mechanism deforms as the attachment mechanism is pulled through the aperture.

17. The optical fiber light guide of claim 15 , wherein the light guide is maintained in a constant position through a compressive force that is formed by the lens and attachment mechanism acting on the trim member.

18. The optical fiber light guide of claim 14 , wherein a connector maintains the proximal portion of the light guide within a light output window of a light source housing.

19. The optical fiber light guide of claim 14 , further comprising:
a trim member defining an aperture having a varied width that corresponds to the rearward portion of the lens, wherein the lens is substantially flush with an A-surface of the trim member in an installed position.
