Abstract
An automated ganged louver assembly is adjusted in orientation by an actuator in the louver header that suspends or supports the louver rotation mechanism. The actuator is energized in response to a determination of solar elevation, which is optionally from a light sensor output via a controller. The light sensor employs an optical element to detect at least one of the sun elevation and azimuth, as well as general exterior light levels. The solar elevation and azimuth can also be determined by calculations from the window orientation and latitude. The optical elements and the controller are coupled to at least one of the louvers or the louver header to provide a self contained system that does not require exterior power or controls, unless desired.
