Dust cover assembly with edge light
First Claim
1. A window assembly comprising:
- a pressure pane;
a bezel proximate a periphery of the pressure pane and defining an inner opening, the bezel including an inner wall with a channel;
an electro-optic element disposed in the inner opening and received in the channel of the inner wall, the electro-optic element operating between a transmissive condition and a dimmed condition, a surface of the electro-optic element exhibiting a first level of spectral reflectivity at least when in the dimmed condition; and
a dust cover assembly proximate the bezel, the dust cover assembly including a light transmitting sheet and a plurality of light sources disposed at edges of the light transmitting sheet and to emit light into the edge of the light transmitting sheet to illuminate a surface of the light transmitting sheet extending between the edges with a diffuse light having a uniform appearance over the surface.

Abstract
A window assembly includes a pressure pane and a bezel proximate a periphery of the pressure pane and defining an inner opening. The bezel includes an inner wall with a channel. An electro-optic element is disposed in the inner opening and is received in the channel of the inner wall. The electro-optic element operates between a transmissive condition and a dimmed condition. A surface of the electro-optic element exhibits a first level of spectral reflectivity at least when in the dimmed condition. The assembly further includes a dust cover assembly proximate the bezel. The dust cover assembly including a light transmitting sheet and a plurality of light sources disposed at edges of the light transmitting sheet and to emit light into the light transmitting sheet to illuminate the light transmitting sheet with a diffuse light.

9. A window assembly comprising:
-
an electro-optic element operating between a transmissive condition and a dimmed condition; a dust cover assembly proximate the electro-optic element and including a light transmitting sheet and a plurality of light sources disposed at edges of the light transmitting sheet to emit light into the edges of the light transmitting sheet to illuminate a surface of the light transmitting sheet extending between the edges with a diffuse light dispersed with a uniform appearance over the surface according to one of;
a predetermined color, a predetermined intensity, and a combined predetermined color and intensity; anda control system coupled with the light sources of the dust cover assembly to control the illumination of the light transmitting sheet. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method for controlling a perceived level of reflectivity of a window assembly, comprising:
-
determining a perceivable level of ambient light reflected by a surface of an electro-optic element within the window assembly; and illuminating a plurality of light sources disposed at edges of a light transmitting sheet adjacent the electro-optic element to cause the light sources to emit light into the edges of the light transmitting sheet, such light being uniformly directed outwardly from the light transmitting sheet toward the cabin to illuminate the light transmitting sheet with a diffuse light at a level greater than the perceivable level of ambient light reflected from the surface of the electro-optic element. - View Dependent Claims (16, 17, 18, 19, 20)
