Abstract

Methods and devices are provided for selectively allowing light to pass through a substantially transparent substrate or blocking the light, at least to some degree. Some embodiments provide a plurality of reflective vanes that can be positioned in at least two positions. According to some such implementations, when the vanes are in an open position, incident light is allowed to pass through the window. The light may reflect from two or more vanes before passing through the window. When a sufficient voltage is applied between vane electrodes and other electrodes, the vanes are pulled down, reflecting back at least some of the incident light. The voltage may be controlled according to detected temperature, ambient light intensity, etc.
