Abstract

A mirror assembly includes a frame, a mirror platform, a light emitting element, a light guide, an interior reflective surface, and a back plate. The mirror platform includes a central reflective portion and a translucent portion. The light emitting element is retained within the frame and driven by a driver. The light guide plate is disposed adjacent the light emitting element and includes two opposed major surfaces that propagate light along the light guide plate. The interior reflective surface is disposed adjacent a rear major surface of the light guide plate. The back plate is affixed to the frame, securing the mirror platform, the light emitting element, the driver, the light guide, and the interior reflective surface therebetween.

First claim

What is claimed is:

1. A mirror assembly, comprising:
a frame;
a mirror platform including a central reflective portion and a translucent portion;
a light emitting element retained within the frame;
a driver configured to drive the light emitting element, the driver retained within the frame;
a light guide plate adjacent to the light emitting element, the light guide plate including two opposed major surfaces that propagate light along the light guide plate;
a reflective surface adjacent a rear major surface of the light guide plate; and
a back plate.

2. The mirror assembly of claim 1 , further comprising:
a front reflective surface facing inwardly and disposed on a surface opposite the central reflective portion.

3. The mirror assembly of claim 2 , wherein the front reflective surface is at least partially-reflective.

4. The mirror assembly of claim 1 , wherein the light emitting element is configured to produce white light.

5. The mirror assembly of claim 1 , wherein an outer dimension of the light guide plate is less than an outer dimension of the reflective surface.

6. The mirror assembly of claim 1 , wherein an overall thickness of the mirror assembly is less than one inch.

7. The mirror assembly of claim 1 , wherein the translucent portion is configured as a single continuous portion surrounding the central reflective portion.

8. The mirror assembly of claim 1 , wherein the light emitting element includes at least one LED.

9. The mirror assembly of claim 1 , wherein the light guide plate includes a plurality of minor surfaces which bound the two opposed major surfaces.

10. The mirror assembly of claim 9 , further comprising
a second light emitting element,
wherein the first light emitting element and the second light emitting element are disposed proximate respective minor surfaces.

11. A mirror assembly, comprising:
a frame;
an internal mirror platform including a central reflective portion and a translucent portion;
an external mirror platform including a central reflective portion and a translucent portion;
a light emitting element retained within the frame;
a driver configured to drive the light emitting element, the driver retained within the frame;
a light guide plate adjacent to the light emitting element, the light guide plate including two opposed major surfaces that propagate light along the light guide plate;
a reflective surface adjacent a rear major surface of the light guide plate; and
a back plate.

12. The mirror assembly of claim 11 , wherein the central reflective portion of the internal mirror platform and the central reflective portion of the external mirror platform are coextensive.

13. The mirror assembly of claim 11 , further comprising:
a front reflective surface facing inwardly and disposed on a surface opposite the central reflective portion of the internal mirror platform.

14. The mirror assembly of claim 13 , wherein the front reflective surface is at least partially-reflective.

15. The mirror assembly of claim 11 , wherein the light emitting element is configured to produce white light.

16. The mirror assembly of claim 11 , wherein an outer dimension of the light guide plate is less than an outer dimension of the reflective surface.

17. The mirror assembly of claim 11 , wherein an overall thickness of the mirror assembly is less than one inch.

18. The mirror assembly of claim 11 , wherein the translucent portion of the internal mirror platform is configured as a single continuous portion surrounding the central reflective portion of the internal mirror platform, and wherein the translucent portion of the external mirror platform is configured as a single continuous portion surrounding the central reflective portion of the external mirror platform.

19. The mirror assembly of claim 11 , wherein the light guide plate includes a plurality of minor surfaces which bound the two opposed major surfaces.

20. The mirror assembly of claim 19 , further comprising
a second light emitting element,
wherein the first light emitting element and the second light emitting element are disposed proximate respective minor surfaces.
