Abstract
The present invention relates to improved electro-optic rearview mirror elements and assemblies incorporating the same.
Claims16
A variable reflectance mirror element, comprising:
- an at least partially reflective coating proximate a first substantially transparent substrate comprising a first periphery area;
- a second substantially transparent substrate secured in a spaced apart relation with respect to said first substantially transparent substrate, said second substantially transparent substrate comprising a second periphery area;
- and a curable plug material positioned between said first substantially transparent substrate and said second substantially transparent substrate such that radiation directed toward said plug material from said first substantially transparent substrate through said at least partially reflective material is attenuated more than radiation directed toward said plug material from said second substantially transparent substrate, wherein said mirror element is configured within a rearview mirror assembly for a motor vehicle and further comprising a light source positioned to project light from said second substrate through said first substantially transparent substrate.
