Abstract

A rearview mirror assembly includes a reflective mirror element and a blind spot indicator system in optical communication with the reflective mirror element and configured to receive an input from a blind spot detector system, wherein the blind spot indicator system includes a first indicator assembly and a second indicator assembly each having a light source and an optic, the optic is in optical communication with the light source. The light sources are configured to emit light that at least partially propagates through the optics and the reflective mirror element if the input received from the blind spot detector indicates the blind spot detector is active or an object is detected in the blind spot.

Claims

1. A rearview mirror assembly in communication with a blind spot detector system, said rearview mirror assembly comprising:

a reflective mirror element; and

a blind spot indicator system in optical communication with said reflective mirror element, and configured to receive an input from the blind spot detector system, wherein said blind spot indicator system comprises;

a first indicator assembly comprising;

a first light source;

a high intensity optic in optical communication with said first light source; and

wherein said first light source is configured to emit light that at least partially propagates through said high intensity optic and said reflective mirror element if the input is received from the blind spot detector system indicating an object is detected; and

a second indicator assembly comprising;

a second light source;

a diffuser optic in optical communication with said second light source; and

wherein said second light source is configured to emit light that at least partially propagates through said diffuser optic and said reflective mirror element if the input is received from the blind spot detector system indicating the blind spot detector is active.

2. The rearview mirror assembly of claim 1, wherein said light emitted from said first light source and viewed through said reflective element is brighter than said light emitted from said second light source and viewed through said reflective element.

3. The rearview mirror assembly of claim 1, wherein said first indicator assembly and said second indicator assembly are illuminated approximately simultaneously.

4. The rearview mirror assembly of claim 1, wherein at least one of said first light source and said second light source comprises at least one light emitting diode.

5. The rearview mirror assembly of claim 1, wherein said reflective element is at least one of an electro-optic reflective element and an electrochromic reflective element.

6. The rearview mirror assembly of claim 1, wherein said reflective element is an exterior rearview element.

7. The rearview mirror assembly of claim 1 further comprising an indicia in optical communication with said second light source, wherein said indicia defines an automobile icon.

8. The rearview mirror assembly of claim 7 further comprising an indicia in optical communication with the first light source, wherein said indicia defines at least one headlight of said automobile icon.

9. The rearview mirror assembly of claim 1 further comprising a reflective coating on a surface of said reflective element, wherein said reflective coating defines an icon in optical communication with at least one of said first light source and said second light source.

10. The rearview mirror assembly of claim 1 further comprising a transflective coating on a surface of said reflective element.

11. The rearview mirror assembly of claim 1, wherein at least one of said first light source and said second light source comprise a light pipe.

12. A rearview mirror assembly in communication with a blind spot detector system, said rearview mirror assembly comprising:

a reflective mirror element; and

a blind spot indicator system in optical communication with said reflective mirror element, and configured to receive an input from the blind spot detector system, wherein said blind spot indicator system comprises;

a first indicator assembly comprising;

a first light source;

a high intensity optic in optical communication with said first light source; and

wherein said first light source is configured to emit light that at least partially propagates through said high intensity optic and said reflective mirror element if the input received from the blind spot detector system indicates an object is detected in the blind spot;

a second indicator assembly comprising;

a second light source;

a diffuser optic in optical communication with said second light source; and

wherein said second light source is configured to emit light that at least partially propagates through said diffuser optic and said reflective mirror element if the input received from the blind spot detector system indicates the blind spot detector is active; and

an indicia in optical communication with at least one of said first and second light sources, wherein said indicia is configured to block at least a portion of light emitted from at least one of said first light source and said second light source and said indicia is viewable through said reflective mirror element.

13. The rearview mirror assembly of claim 12, wherein said indicia is on at least one of the first surface and the second surface of a substrate of said reflective mirror element.

14. The rearview mirror assembly of claim 12, wherein said reflective mirror element is at least one of an electro-optic reflective element and an electrochromic reflective mirror element.

15. The rearview mirror assembly of claim 12, wherein the outline of said indicia is configured to be illuminated when said light is emitted from said second light source and at least partially propagates through said diffuser optic and wherein a portion of said indicia is configured to be illuminated at a higher intensity then said outline when said light is emitted from said first light source and at least partially propagates through said high intensity optic.

16. A rearview mirror assembly in communication with a blind spot detector system for a vehicle, said rearview mirror assembly comprising:

a reflective mirror element; and

a blind spot indicator system in optical communication with said reflective mirror element, and configured to receive an input from the blind spot detector system, wherein said blind spot indicator system comprises;

a first indicator assembly comprising; and

a first light source;

a high intensity optic in optical communication with said first light source; and

wherein said first light source is configured to emit light that at least partially propagates through said high intensity optic and said reflective mirror element if the input is received from the blind spot detector system indicating an object is detected in a first area with respect to the vehicle;

a second indicator assembly comprising;

a second light source;

a diffuser optic in optical communication with said second light source; and

wherein said second light source is configured to emit light that at least partially propagates through said diffuser optic and said reflective mirror element if the input is received from the blind spot detector system indicating an object is detected in a second area with respect to the vehicle.

17. The rearview mirror assembly of claim 16, wherein said reflective mirror element is at least one of an electro-optic reflective element and an electrochromic reflective mirror element.

18. The rearview mirror assembly of claim 16, wherein said first light source and said second light source comprise at least one light emitting diode.
