WINDOW WITH SHADE

摘要

A window assembly includes an outer window panel, an inner window panel, a conductive layer disposed at an inner surface of the inner window panel, a spacer element, and a roller shade disposed within an interpane cavity established between the inner and outer window panels by the spacer element. The roller shade has an end fixedly attached at an anchor stop along a perimeter portion of the spacer element. A dielectric layer is disposed between the roller shade and the conductive layer. The roller shade is electrically deployable to coil and uncoil between a coiled light transmitting condition and an at least partially uncoiled light attenuating condition. The roller shade is electrically operable via applying a voltage at the transparent conductive layer and at the anchor stop to uncoil the roller shade from the coiled light transmitting condition to the at least partially uncoiled light attenuating condition.

1. A window assembly comprising:
an outer window panel; an inner window panel; a conductive layer disposed at an inner surface of said inner window panel; a spacer element disposed between said inner and outer window panels to establish an interpane cavity between said inner and outer window panels; a roller shade disposed within said interpane cavity, wherein said roller shade has an end fixedly attached at an anchor stop along a perimeter portion of said spacer element; a dielectric layer disposed between said roller shade and said conductive layer; wherein said roller shade is electrically deployable to coil and uncoil between a coiled light transmitting condition, where said roller shade is coiled along said perimeter portion of said spacer element and functions to substantially allow light transmission through said window assembly, and an at least partially uncoiled light attenuating condition, where said roller shade is uncoiled to at least partially cover a surface of said inner window panel and functions to at least partially attenuate light transmission through said window assembly; wherein said roller shade is electrically operable via applying a voltage at said transparent conductive layer and at said anchor stop to uncoil said roller shade from said coiled light transmitting condition to said at least partially uncoiled light attenuating condition, and wherein electrical connection is made between said roller shade and a power source to provide electrical power to said roller shade; and wherein said roller shade comprises a laminate material comprising a dielectric material or layer, a conductive material or layer and an ink or opaque material or layer, and wherein said conductive layer is disposed at a lower portion of said dielectric layer and said ink or opaque layer is disposed at a lower surface of said conductive layer.
