Abstract

A vehicle light system is provided herein. The vehicle light system includes a seal including an engagement member having first and second portions defining a channel and a cavity. The cavity is separated from the channel by the first portion. The first and second portions have varied opacities. A light guide is disposed within the cavity. A light source is operably coupled with the light guide.

First claim

What is claimed is:

1. A vehicle light system comprising:
a seal including an engagement member configured to engage a vehicle door, the engagement member having first and second portions, the first and second portions of the engagement member defining a channel and a cavity, wherein the cavity is separated from the channel by the first portion, and wherein the first portion is positioned between an attachment member of the seal and the second portion, the first and second portions having varied opacities;
a light guide disposed within the cavity, wherein the light guide is formed from a flexible material configured to accept repetitive deformation with minimized structural degradation of the light guide; and
a light source operably coupled with the light guide.

2. The vehicle light system of claim 1 , wherein the flexible material of the light guide has a Durometer hardness of less than about 110 Shore A.

3. The vehicle light system of claim 1 , wherein the seal is disposed proximate an opening of a vehicle that is defined by one or more vehicle body panels.

4. The vehicle light system of claim 2 , wherein the light source is disposed within a housing, the housing disposed on an opposing side of the body panel from the seal.

5. The vehicle light system of claim 1 , wherein the first portion is opaque and the second portion is translucent.

6. The vehicle light system of claim 1 , wherein the first and second portions of the seal are integrally coupled with one another through an extrusion process.

7. The vehicle light system of claim 1 , wherein the light guide fills a portion of the cavity.

8. The vehicle light system of claim 1 , wherein the second portion of the engagement member defines an integrally formed lens to direct light in a desired direction.

9. The vehicle light system of claim 1 , further comprising:
a tapered core within the light guide to direct light emitted from the light source outwardly from the light guide.

10. The vehicle light system of claim 1 , further comprising:
a retainer disposed through the second portion of the engagement member and coupled with a retaining portion of the light guide.

11. The vehicle light system of claim 1 , further comprising:
one or more optical fiber strands within the light guide.

12. The vehicle light system of claim 1 , further comprising:
a luminescent structure disposed on a portion of the seal and configured to luminesce in response to light emitted from the light source.

13. A vehicle light system comprising:
a seal including an attachment member for coupling the seal with a side of a vehicle body and an engagement member for engaging with a vehicle door, the engagement member defining both a channel and a separate cavity extending within the length of the engagement member, and further wherein the cavity is defined outboard of the channel and the attachment member;
a light guide disposed within the cavity; and
a light source operably coupled with the light guide, the light source on an opposing side of the vehicle body panel from the seal.

14. The vehicle light system of claim 13 , wherein a first portion of the engagement member has a first transparency and a second portion of the engagement member has a second transparency that is different from the first transparency.

15. The vehicle light system of claim 13 , wherein the light guide is formed from one or more optical fiber strands.

16. The vehicle light system of claim 13 , further comprising:
a tapered core within the light guide.

17. A vehicle light system comprising:
a seal extending about a periphery of a vehicle body panel and including:
an attachment member configured to couple the seal with the vehicle body panel; and
an engagement member having a translucent portion, wherein the engagement member is positioned outboard of the attachment member, and wherein the engagement member is configured to be deformed when contacted by a door;

a light guide disposed within a channel defined by, and deformable with, the engagement member; and
a light source operably coupled with the light guide.

18. The vehicle light system of claim 17 , wherein the light guide defines a retaining portion.

19. The vehicle light system of claim 18 , further comprising:
a retainer configured to operably couple the retaining portion of the light guide to the engagement member.

20. The vehicle light system of claim 17 , wherein the light guide is disposed within a housing, the housing disposed on an opposing side of a body panel from the engagement member.
