Abstract:
1. A window for an enclosed region, comprising: a transparent panel covering a part of the enclosed region and having one side facing an interior of the enclosed region and another side facing an exterior of the enclosed region; at least one flat electroluminescent light element with plural layers and including a transparent electrode provided at said transparent panel at a side of the electroluminescent light element facing the interior of the enclosed region and another electrode provided at said transparent pane at a side of the electroluminescent light element facing the exterior of the enclosed region; an opaque element provided at said transparent panel to be separate from, exterior to, and in addition to, said another electrode such that said panel has both an opaque surface portion and a surface portion allowing light to pass therethrough; wherein said at least one flat electroluminescent light element is positioned relative to said opaque surface portion such that the passage of light from said at least one flat electroluminescent light element to the exterior of the enclosed region is substantially obstructed by said opaque surface portion, and the passage of light from said at least one flat electroluminescent light element to the interior of the enclosed region is substantially unobstructed by said opaque surface portion; and an electrical supply voltage connectable to the transparent electrode.
