Abstract
An electrochromic variable reflectance mirror for automotive vehicles is provided. The mirror has front and rear spaced elements, each having front and rear surfaces. The rear surface of the front element has a layer of transparent conductive material disposed thereon. The front surface of the rear element has a reflector/electrode including at least a layer of highly reflective material and a flash over-coat layer. The front and rear spaced elements are sealably bonded together in a spaced-apart relationship to define a chamber. The chamber contains at least one solution-phase electrochromic material in contact with the flash layer. The reflector/electrode is effective to reflect light through the medium and the front element when the light reaches the reflector/electrode after passing through the front element and the at least one electrochromic material. The reflector/electrode is constructed such that the electrochromic variable reflectance mirror exhibits a reflectance of at least 70%.
Claims (7)
1. An electrochromic variable reflectance mirror for automotive vehicles, comprising front and rear spaced elements, each having front and rear surfaces, said rear surface of said front element having a layer of transparent conductive material disposed thereon, said front surface of said rear element having a reflector/electrode including at least a layer of highly reflective material and a flash over-coat layer, where said front and rear spaced elements are sealably bonded together in a spaced-apart relationship to define a chamber, where said chamber contains at least one solution-phase electrochromic material in contact with said flash over-coat layer, and where said reflector/electrode is effective to reflect light through said at least one solution-phase electrchromic material and said front element when said light reaches said reflector/electrode after passing through said front element and said at least one electrochromic material, wherein said reflector/electrode is constructed such that the electrochromic variable reflectance mirror exhibits a reflectance of at least 70%.
2. The mirror according to claim 1, where said highly reflective material is a material selected from the group consisting of silver and silver alloys, where the silver alloy is a combination of silver and an element selected from the group consisting essentially of gold, platinum, rhodium, and palladium.
3. The mirror according to claim 2, where said reflector/electrode further includes a base layer disposed beneath said highly reflective alloy.
4. The mirror according to claim 3, where said base layer comprises a material selected from the group consisting essentially of: chromium; chromium-molybdenum-nickel alloys; nickel-iron-chromium alloys; stainless steel; and titanium.
5. The mirror according to claim 2, where said reflector/electrode further includes at least one intermediate layer disposed between said highly reflective alloy and said base layer, where said intermediate layer comprises a material selected from the group consisting essentially of: molybdenum; rhodium; stainless steel; and titanium.
6. The mirror according to claim 1, where said flash over-layer comprises a material selected from the group consisting essentially of: rhodium, molybdenum, and platinum.
7. The mirror according to claim 1, wherein said flash over-coat layer is sufficiently thin to allow said layer of highly reflective material to contribute to the reflectivity of the mirror.
