SWITCHABLE ELECTROCHROMIC DEVICES WITH EVEN SWITCHING AND SHADOWING OF PREFERABLE AREAS Russian patent published in 2005 - IPC

FIELD: electrochromic devices.

SUBSTANCE: system includes multiple first means positioned at a distance from one another, being in contact with conductive covering and made with possible feeding of electric current to first conductive covering, and multiple second means positioned at a distance from one another, being in contact with second conductive covering and made with possible feeding of electric current to second conductive covering. Multiple first means distanced from one another and multiple second means distanced from one another are positioned along perimeter of window assembly. In addition, window assembly can include controller, made with possible control of feeding of electric current to selected means from multiple first means positioned at a distance from one another and to selected means from multiple second means positioned at a distance from one another, so that coefficient of light penetration through first portion of electrochromic environment is different from coefficient of light penetration through second portion of electrochromic environment.

EFFECT: higher efficiency, simplified construction.
