Abstract
An inside non-planar electrochromic mirror includes front and rear non-planar elements, a layer of transparent conductive material, a reflector and a perimeter sealing member which bonds the front and rear non-planar elements in a spaced apart relationship. The front and rear non-planar elements each include front and rear surfaces. A layer of transparent conductive material is disposed on the rear surface of the front non-planar element. The reflector can be disposed on either side of the rear non-planar element. When the reflector is on the rear surface of the rear non-planar element then the front surface of the rear non-planar element contains a layer of transparent conductive material. When the reflector is on the front surface of the rear element it must be constructed of conductive material. The perimeter sealing member bonds the front and rear non-planar elements and defines a chamber therebetween. The chamber contains at least one electrochromic material. The reflector is effective to reflect light through the chamber and the front non-planar element when light reaches the reflector after passing through the front non-planar element and the chamber.
