Abstract

An electrical control system is disclosed for controlling a plurality of variable transmittance windows. The electrical control system comprises a master control circuit and user input circuits for supplying control signals representing transmittance levels for the variable transmission windows, and a plurality of slave window control circuits coupled to the master control circuit, user input circuits and the variable transmittance windows. Each slave window control circuit controls the transmittance of at least one of the variable transmission windows in response to control signals received from the master control circuit and / or user input circuits. Also disclosed are novel methods for the manufacture of an electrochromic device used in variable transmittance windows. Novel structural features for improving heat transfer away from the windows, shielding the window from external loads, and improving the electrical performance of the windows are also disclosed.

Description

technical field [0001] The present invention generally relates to variable transmission windows. More particularly, the present invention relates to control systems for controlling transmission of variable transmission windows, and to various configurations of variable transmission windows and methods for manufacturing variable transmission windows. Background technique [0002] Variable transmittance optical filters, such as electrochromic optical filters, have been proposed for building windows, sunroofs and windows, convertible tops and rear view mirrors of automobiles. The variable transmittance light filter reduces the transmittance of direct or reflected sunlight through the window during the day without reducing such transmittance at night. This way the light filter not only reduces annoying glare and ambient brightness, but also reduces fading and heat generation caused by the transmission of daylight through the window. [0003] Variable transmission windows have ...
