Insulated glazing unit and controller providing energy savings and privacy

摘要

An insulated glazing unit includes a spacer defining a framed area, first and second glazing panes attached to the spacer, a pane conductive layer on an inner surface of the first glazing pane, and a dielectric layer disposed on the pane conductive layer. A shade for use with the insulated glazing unit is affixed to the first glazing pane. The shade includes one or more layers selected from a resilient layer, a substantially transparent shade conductive layer, and an opaque shade conductive layer. When an electric drive is applied between the pane conductive layer and the shade conductive layer, a potential difference between the pane conductive layer and the shade conductive layer causes the shade to extend from a retracted configuration to an extended configuration. The shade can further include at least one ink coating layer including pigments that selectively reflect or absorb certain visible colors and infrared.

1. An insulated glazing unit having controllable radiation transmittance, said insulated glazing unit comprising:
a spacer defining a framed area capable of allowing radiation transmission therethrough; a first glazing pane attached to said spacer; a second glazing pane attached to said spacer, said glazing panes arranged such that an inner surface of said first glazing pane and an inner surface of said second glazing pane face each other and are spaced apart from each other; a pane conductive layer disposed on said inner surface of said first glazing pane; a dielectric layer disposed on said pane conductive layer; a shade affixed to said first glazing pane, said shade including a resilient layer and a substantially transparent shade conductive layer, wherein said shade is adapted to extend along a length of the framed area from a retracted configuration having a first surface area substantially permitting radiation transmission through said framed area to an extended configuration having a second surface area substantially controlling radiation transmission through said framed area; and a controller operable to apply and remove an electric drive of voltage or current between said pane conductive layer and said substantially transparent shade conductive layer, whereby, when an electric drive of voltage or current is applied between said pane conductive layer and said substantially transparent shade conductive layer a potential difference between said pane conductive layer and said substantially transparent shade conductive layer causes said shade to extend from said retracted configuration to said extended configuration.
