Abstract

A lighted exterior mirror system for a vehicle includes an exterior mirror assembly having a mountain portion, an exterior mirror housing and a reflective element. A signal light assembly is disposed at the exterior mirror housing and includes at least one light emitting source and a light conduiting element, which has a body portion having a plurality of light conduiting portions established therein. Each of the light conduiting portions has a light receiving end and a light emitting end. The light conduiting members are arranged in a generally radial fashion so that the light emitting ends are arranged to follow an exterior contour of the exterior mirror housing. The light emitted by the light emitting source is received at the light receiving ends and is emitted from the light emitting ends along the exterior contour of the exterior mirror housing at which the light conduiting element is disposed.

Claims

1. A lighted exterior mirror system for a vehicle comprising:

an exterior mirror assembly comprising a mounting portion configured for mounting at a vehicle equipped with said lighted exterior mirror system, an exterior mirror housing, and a reflective element;

wherein said reflective element comprises a substrate having a reflective coating on a surface thereof;

an actuator disposed at said exterior mirror housing and operable to adjust the rearward field of view of said reflective element when said exterior mirror assembly is mounted at the equipped vehicle;

a signal light assembly disposed at said exterior mirror housing of said exterior mirror assembly and unaffected by adjustment of the rearward field of view of said reflective element by operation of said actuator;

wherein said signal light assembly comprises at least one light emitting source and a light conduiting element;

wherein said light conduiting element comprises a body portion having a plurality of light conduiting portions established therein, and wherein each of said light conduiting portions comprises a light receiving end proximate to said at least one light emitting source and a light emitting end distal from said light receiving end;

wherein said plurality of light conduiting members are arranged in a generally radial fashion so that said light emitting ends are arranged to follow an exterior contour of said exterior mirror housing; and

wherein light emitted by said at least one light emitting source is received at said light receiving ends of said plurality of said light conduiting portions and is emitted from said light emitting ends of said plurality of said light conduiting portions along the exterior contour of said exterior mirror housing at which said light conduiting element is disposed.

2. The lighted exterior mirror system of claim 1, wherein each of said light conduiting portions comprises at least one light reflecting surface to reflect light emitted by said at least one light emitting source along said light conduiting portion toward said light receiving end.

3. The lighted exterior mirror system of claim 2, wherein said light reflecting surfaces terminate before said light emitting surfaces and within said body portion of said light conduiting element.

4. The lighted exterior mirror system of claim 2, wherein said light reflecting surfaces terminate at said light emitting surfaces.

5. The lighted exterior mirror system of claim 1, wherein said at least one light emitting source comprises a plurality of light emitting sources.

6. The lighted exterior mirror system of claim 5, wherein said light receiving end of each of said light conduiting portions receives light emitted by a respective one of said plurality of light emitting sources.

7. The lighted exterior mirror system of claim 6, wherein each of said light emitting sources is optically coupled with a respective one of said light receiving ends of said light conduiting portions.

8. The lighted exterior mirror system of claim 1, wherein said light conduiting element is disposed at a lower region of said mirror casing and wherein said light emitting ends of said plurality of said light conduiting portions are arranged along the exterior contour of an outboard side region of said exterior mirror housing.

9. The lighted exterior mirror system of claim 1, wherein said light conduiting element is removably received in a slot established at a lower region of said exterior mirror housing.

10. The lighted exterior mirror system of claim 9, wherein said body portion comprises an electrical connector for electrically connecting said at least one light emitting source to an electrical system of the equipped vehicle when said light conduiting element is received in said slot.

11. The lighted exterior mirror system of claim 1, wherein said body portion of said light conduiting element comprises a lower body portion and an upper body portion and wherein said lower and upper body portions are attachable together to assemble said body portion with said at least one light emitting source disposed therein.

12. The lighted exterior mirror system of claim 1, wherein said body portion of said light conduiting element comprises a polymeric body portion.

13. The lighted exterior mirror system of claim 1, wherein said body portion of said light conduiting element comprises at least one of (a) a light transmitting plastic material, (b) a light transmitting polycarbonate material and (c) a light transmitting acrylic material.

14. The lighted exterior mirror system of claim 1, wherein said body portion of said light conduiting element is substantially rigid.

15. The lighted exterior mirror system of claim 1, wherein said at least one light emitting source comprises at least one light emitting diode.

16. The lighted exterior mirror system of claim 1, wherein said at least one light emitting source comprises at least one laser diode.

17. The lighted exterior mirror system of claim 1, wherein said exterior mirror housing is movably connected to said mounting portion by a connection chosen from at least one of a break-away connection and a power-fold connection.

18. The lighted exterior mirror system of claim 1, wherein said reflective element comprises a non-electro-optic reflective element.

19. The lighted exterior mirror system of claim 1, wherein said reflective element comprises an electrochromic reflective element.

20. The lighted exterior mirror system of claim 1, wherein said reflective element is supported on a reflective element support member, said reflective element support member mounting to said actuator.
