Abstract

An exterior rear view mirror assembly for a motor vehicle has a reflecting element, a clamping plate, a first adhesive element fixing the reflective element to the clamping plate, and a watertight illumination module. The watertight illumination module has a printed circuit board arranged within the watertight illumination module at an angle of 1 to 90 degrees relative to the clamping plate, at least one light emitting diode arranged on the printed circuit board, an inner reflective surface having a reflectivity coefficient of at least 30% and at least partially exposed to the light emitted by the at least one light emitting diode, and an outer portion with at least one hole with a sealing element engaged therein.

Claims

1. An exterior rear view mirror assembly for a motor vehicle comprising:

a reflecting element with a multidimensional image;

a clamping plate;

a first adhesive element fixing the reflective element to the clamping plate; and

a watertight illumination module;

wherein the watertight illumination module is detachably attached to the first adhesive element and wherein the watertight illumination module further comprises;

an inner portion with an inner reflective surface with a reflectivity coefficient of at least 30%, the inner reflective surface at least partially exposed to the light emitted by the at least one light emitting diode,

a printed circuit board arranged within the inner portion at an angle of 1 to 90 degrees relative to the clamping plate,

at least one light emitting diode arranged on the printed circuit board, and an outer portion with at least one hole with a sealing element engaged therein.

2. The exterior rear view mirror assembly as claimed in claim 1, wherein the printed circuit board is arranged in an outermost part of the inner portion and the inner reflective surface is comprised in an innermost part of the inner portion.

3. The exterior rear view mirror assembly as claimed in claim 1, wherein the reflecting element has a metalized first surface.

4. The exterior rear view mirror assembly as claimed in claim 1, wherein the reflecting element has a metalized second surface.

5. The exterior rear view mirror assembly as claimed in claim 1, wherein the watertight illumination module is detachably attached to the first adhesive element by a second adhesive element.

6. The exterior rear view mirror assembly as claimed in claim 1, wherein the first adhesive element is of the heating type.

7. The exterior rear view mirror assembly as claimed in claim 1, wherein the inner reflective surface of the watertight illumination module is provided with a random structure.

8. The exterior rear view mirror assembly as claimed in claim 1, wherein the inner reflective surface of the watertight illumination module is provided with a textured structure.

9. The exterior rear view mirror assembly as claimed in claim 1, wherein the inner reflective surface is a metalized surface.

10. The exterior rear view mirror assembly as claimed in claim 1, wherein the sealing element is a plastic grommet.

11. The exterior rear view mirror assembly as claimed in claim 1, wherein the multidimensional image is provided on the second surface of the reflective element.

12. The exterior rear view mirror assembly as claimed in claim 1, wherein the multidimensional image is provided on the first surface of the reflective element.

13. The exterior rear view mirror assembly as claimed in claim 1, further comprising a light diffusing film disposed between the reflective element and the watertight illumination module.

14. The exterior rear view mirror assembly as claimed in claim 1, further comprising a reflective layer opaque to ambient light but transmissive to the light emitted by the watertight illumination module, having a thickness comprised between 1 nm and 1 μ

m and located between the multidimensional image and the watertight illumination module.

15. The exterior rear view mirror assembly as claimed in claim 14, wherein the reflecting layer is monolayer.

16. The exterior rear view mirror assembly as claimed in claim 14, wherein the reflective layer is multilayer.

17. The exterior rear view mirror assembly as claimed in claim 14, wherein the multidimensional image is provided on the first surface of the reflective element, and the reflective layer is provided at least partially on the second surface of the reflective element.

18. The exterior rear view mirror assembly as claimed in claim 14, further comprising a light diffusing film disposed between the reflective element and the watertight illumination module, wherein the reflective layer is provided on the light diffusing film.

19. The exterior rear view mirror assembly as claimed in claim 1, wherein the watertight illumination module emits light indirectly through a reflective element by means of the at least one light emitting diode.

20. The exterior rear view mirror assembly as claimed in claim 1, wherein the watertight illumination module has at least one cable connecting the printed circuit board with a connector, the at least one cable traversing the sealing element.

21. The exterior rear view mirror assembly as claimed in claim 20, wherein the at least one cable is fixed to the clamping plate by at least one clip.

22. The exterior rear view mirror assembly as claimed in claim 1, wherein the watertight illumination module has an integrated connector.
