Variable reflectance mirror
First Claim
1. A variable reflectance mirror, comprising:
- a color layer that can develop color by binding with hydrogen or lithium;
a transparent substrate having one surface formed directly in contact with one surface of the color layer, and an opposite surface that contacts ambient air;
a light-reflecting layer formed on the side of the color layer opposite to the surface thereof on which the transparent substrate is in direct contact with, which allows transmission of hydrogen or lithium; and
a supplying device for supplying hydrogen or lithium to the color layer,wherein a transparent intermediate layer, which allows transmission of hydrogen or lithium and which has a refractive index smaller than that of the color layer, is formed between the color layer and the light-reflecting layer to increase the reflectivity of the resulting variable reflectance mirror, said layer having one surface in direct contact with the side of the color layer opposite to the surface thereof on which the transparent substrate is in direct contact with, and an opposite surface in direct contact with said light-reflecting layer.

Abstract
The present invention provides a variable reflectance mirror, comprising a color layer that develops color by binding to hydrogen or lithium, a transparent substrate formed on or above one surface of the color layer, a light-reflecting layer which allows transmission of hydrogen or lithium provided on the side of the color layer opposite to the surface thereof on which the transparent substrate is formed, and a supplying device for supplying hydrogen or lithium to the color layer, wherein a transparent intermediate layer which allows transmission of hydrogen or lithium and having a refractive index smaller than that of the color layer is formed between the color layer and the light-reflecting layer.

13. A variable reflectance mirror, comprising:
-
a color layer that can develop color by binding with hydrogen or lithium; a transparent substrate having one surface formed directly in contact with one surface of the color layer, and an opposite surface that contacts ambient air; a light-reflecting layer formed on the side of the color layer opposite to the surface thereof on which the transparent substrate is in direct contact with, which allows transmission of hydrogen or lithium; and a supplying device for supplying hydrogen or lithium to the color layer including an electrode layer, a cell structure containing an electrolytic fluid, and a power supply unit, wherein a transparent intermediate layer having a thickness of less than 15 nm, which allows transmission of hydrogen or lithium and having a refractive index smaller than that of the color layer, is formed between the color layer and the light-reflecting layer to increase the reflectivity of the resulting variable reflectance mirror, and has one surface in direct contact with the side of the color layer opposite to the surface thereof on which the transparent substrate is in direct contact with, and an opposite surface in direct contact with said light-reflecting layer.

14. A method for making variable reflectance mirror that comprises the steps of:
-
providing a color layer that can develop color by binding with hydrogen or lithium; forming one surface of a transparent substrate directly in contact with one surface of the color layer; forming a light-reflecting layer which allows transmission of hydrogen or lithium on the side of the color layer opposite to the surface thereof on which the transparent substrate is formed; providing a supplying device for supplying hydrogen or lithium to the color layer that includes a cell structure containing an electrolytic fluid, and forming a transparent intermediate layer, which allows transmission of hydrogen or lithium and having a refractive index smaller than that of the color layer, between the color layer and the light-reflecting layer one surface in direct contact with the side of the color layer opposite to the surface thereof on which the transparent substrate is in direct contact with, and an opposite surface in direct contact with said light-reflecting layer, wherein both the color layer and the light-reflecting layer have microscopic undulating surface irregularities which are substantially uniform, and wherein a thickness of the intermediate layer is selected to be a distance between the highest and lowest edges of the irregularities.
