Local light attenuation for improving reliability of electronic dimmable windows

摘要

A window system and method of attenuating light in a window system for improving usefulness and reliability of an electronic dimmable window in the window system. An automatically adjusting photochromatic material is integrated into a window pane of the window system such that the electronic dimmable window is positioned between the automatically adjusting photochromatic material in the window pane and a dust cover of the window system. The automatically adjusting photochromatic material is formulated to attenuate incoming light in a local area of the photochromatic material in response to a solar flux intensity of the incoming light in the local area being greater than or equal to a threshold intensity while areas outside the local area of the photochromatic material that are subjected to solar flux intensity less than the threshold intensity do not attenuate incoming light.

1. A window system comprising:
a window pane comprising an automatically adjusting photochromatic material formulated to attenuate incoming light in a local area of the photochromatic material in response to a solar flux intensity of the incoming light in the local area being greater than or equal to a threshold intensity while areas outside the local area of the photochromatic material that are subjected to solar flux intensity less than the threshold intensity do not attenuate incoming light; an electronic dimmable window; and a dust cover positioned such that the electronic dimmable window is between the automatically adjusting photochromatic material in the window pane and the dust cover.
