ABSTRACT:
A window device for controlling the transmission of solar radiation therethrough, having a first diffuser means forming the exterior of the device for diffusing incoming solar radiation, a second diffuser means spaced interiorly from the first diffuser means for further diffusing the incoming solar radiation, a plurality of substantially planar vanes situated between the first and second diffuser means, with each of the vanes having reflective surfaces and being pivotal about an axis passing through its center of gravity, the vanes being interconnected to move substantially in unison, means for automatically controlling the inclination of the vanes about their respective axes in response to the amount of solar radiation transmitted past the vanes, a plurality of substantially planar insulating panels spaced interiorly from the second diffuser means, with each of the panels being pivotable about an axis passing through its center of gravity and being interconnected to move substantially in unison, and means for automatically controlling the inclination of the panels about their respective axes in response to the amount of solar radiation transmitted past the vanes, whereby the amount of solar radiation transmitted through the window is controlled. Also, active and passive solar collection systems employing such a window device.
