ELECTRONICALLY CONTROLLED INSULATED GLAZING UNIT PROVIDING ENERGY SAVINGS AND PRIVACY

摘要

An insulated glazing unit (100) includes a spacer (150) defining a framed area, first and second glazing panes (320) attached to the spacer (150), a pane conductive layer (322) on an inner surface of the first glazing pane (320), and a dielectric layer (324) disposed on the pane conductive layer (322). A shade (310) for use with the insulated glazing unit (100) is affixed to the first glazing pane (320). The shade (310) includes one or more layers selected from a resilient layer (316), a substantially transparent shade conductive layer (318), and an opaque shade conductive layer (325). When an electric drive is applied between the pane conductive layer (322) and the shade conductive layer (318, 325), a potential difference between the pane conductive layer (322) and the shade conductive layer (318, 325) causes the shade (310) to extend from a retracted configuration to an extended configuration. The shade (310) can further include at least one ink coating layer (340) including pigments that selectively reflect or absorb certain visible colors and infrared.
