LOW COST DYNAMIC INSULATED GLAZING UNIT

摘要

An insulated glazing unit (100) has controllable radiation transmittance. Peripheries of first and second glazing panes (120) are attached and spaced apart facing each other and then attached to a supporting structure (102). A conductive layer (322) is disposed atop the first glazing pane (320) inner surface as a fixed position electrode. A dielectric (324) is located atop the conductive layer. A coiled spiral roll, variable position electrode (310) is between the first and second glazing panes, a width of its outer edge attached to the dielectric. A first electrical lead (132) is connected to the variable position electrode's conductive layer. A second electrical lead (134) is connected to the conductive layer atop the first glazing pane. Applied voltage between the first and second electrical leads creates a predetermined potential difference between the electrodes, and the variable position electrode unwinds and rolls out to at least partially cover the first glazing pane, at least reducing the intensity of passing radiation.
