Abstract

A mirror assembly for a vehicle with a light is provided. The mirror assembly includes an exterior mirror assembly that is attached to the vehicle. A light source is removably positioned inside the exterior mirror assembly. A waveguide is positioned to transmit light from the light source to a location outside the exterior mirror assembly. The light source is secured to a light holder which is positioned inside and attached to the exterior mirror assembly. The light holder is configured to efficiently couple light from the light source to the waveguide.

Claims

1. A mirror assembly for a vehicle comprising:

a mirror housing having an opening located at a lower portion of the housing;

a mirror secured to the mirror housing;

a light source mounted within the mirror housing; and

a waveguide mounted within the mirror housing and extending through the housing from an input end to an output end, wherein the input end is oriented proximate the light source to receive light emanating from the light source and the output end is located within the opening in the mirror housing such that the output end forms both a lower, exterior surface portion of the mirror housing and a front, exterior surface portion of the mirror housing, and wherein light entering the input end of the waveguide from the light source is conducted by internal reflection within the waveguide and exits the mirror housing through the output end of the waveguide.

2. The mirror assembly of claim 1, further comprising a light holder, positioned inside and attached to the mirror assembly,

wherein the light source is secured to the light holder.

3. The mirror assembly of claim 2, wherein the light holder is configured to efficiently couple light from the light source to the waveguide.

4. The mirror assembly of claim 1, wherein the waveguide is configured to focus light at a location outside the mirror housing.

5. The mirror assembly of claim 1, wherein the waveguide is configured to diffuse light at a location outside the mirror housing.

6. The mirror assembly of claim 1, wherein a core of the waveguide is formed of plastic.

7. The mirror assembly of claim 6, wherein a cladding of the waveguide is air surrounding the waveguide.

8. The mirror assembly of claim 6, wherein a cladding of the waveguide is formed by coating the waveguide with a material that has a lower refractive index than a refractive index of the plastic.

9. The mirror assembly of claim 8, wherein the coating is used to secured the waveguide to the exterior mirror housing.

10. The mirror assembly of claim 6, wherein the waveguide is formed as a part of the mirror housing.

11. The mirror assembly of claim 1, wherein the exterior mirror housing comprises a slot which receives the light source and waveguide.

12. The mirror assembly of claim 1, wherein the waveguide includes an outer reflective layer positioned at an end of the waveguide.

13. The mirror assembly of claim 1, wherein the transmitted light is polarized.

14. The mirror assembly of claim 1, wherein the transmitted light is a color chosen to depend on light source usage.

16. The mirror assembly of claim 1, wherein the waveguide has a rectangular cross sectional area perpendicular to a direction of the light.

17. The mirror assembly of claim 1, wherein the waveguide comprises an outer surface that transmits light at a direction dependent on a normal angle to the outer surface.

15. A mirror assembly for a vehicle comprising:

a mirror housing having an opening located at a lower portion of the housing;

a mirror secured to the mirror housing;

a light source mounted within the mirror housing; and

a waveguide mounted within the mirror housing and extending through the housing from an input end to an output end, wherein the input end is oriented relative to the light source to receive light emanating from the light source and the output end is located within the opening in the mirror housing such that the output end forms both a lower, exterior surface portion of the mirror housing and a front, exterior surface portion of the mirror housing, and wherein light entering the input end of the waveguide from the light source is conducted by internal reflection within the waveguide and exits the mirror housing through the output end of the waveguide;

wherein the waveguide is attached to the mirror housing.

18. A mirror assembly for a vehicle comprising:

a mirror housing having an opening located at a lower portion of the housing;

a mirror secured to the mirror housing;

a light source mounted within the mirror housing; and

a waveguide mounted within the mirror housing and extending through the housing from an input end to an output end, wherein the input end is oriented relative to the light source to receive light emanating from the light source and the output end is located within the opening in the mirror housing such that the output end forms both a lower, exterior surface portion of the mirror housing and a front, exterior surface portion of the mirror housing, and wherein light entering the input end of the waveguide from the light source is conducted by internal reflection within the waveguide and exits the mirror housing through the output end of the waveguide;

wherein the waveguide has a cylindrical cross sectional area perpendicular to a direction of the light.

19. A mirror assembly for a vehicle comprising:

a mirror housing;

a mirror secured to the mirror housing;

a bulb holder positioned inside the mirror housing, the bulb holder having an opening through which light exits the bulb holder;

a light source located within the bulb holder;

a waveguide having a first end located within the opening in the bulb holder and conforming in shape to said opening so that substantially all of the light exiting the bulb holder enters the waveguide, the waveguide further including a second end located near an opening in the mirror housing to transmit the light out of the mirror housing;

wherein light entering the first end of the waveguide is conducted by internal reflection within the waveguide and exits through the opening in the mirror housing via the second end of the waveguide.

20. The mirror assembly of claim 19, wherein the second end of the waveguide fits within the opening in the mirror housing and forms an exterior surface of the mirror housing.

21. The mirror assembly of claim 19, wherein the opening in the mirror housing comprises a slot in the mirror housing and wherein the second end of the waveguide is configured to direct light rearwardly from the mirror housing.

22. The mirror assembly of claim 21, wherein the waveguide is further configured to direct light downwardly from the mirror housing.

23. A mirror assembly for a vehicle comprising:

a mirror housing having an opening located at a lower portion of the housing;

a mirror secured to the mirror housing;

a light source mounted within the mirror housing;

a waveguide mounted within the mirror housing and being arranged within the housing to receive light from the light source and conduct the light to the opening in the housing, wherein the waveguide directs the received light both downwardly and rearwardly from the opening to thereby provide both ground and rearwardly-directed illumination from the mirror housing.

24. The mirror assembly of claim 23, wherein a portion of the waveguide fits within the opening in the mirror housing and forms an exterior surface of the mirror housing.
