Patent ID: 7995277

Claim:
An apparatus for controlling energy from a skylight of a structure, the structure having a ceiling and a floor, the apparatus comprising: a plurality of vanes positionable beneath the skylight and angularly adjustable to control solar radiation entering the structure through the skylight, the vanes having a skylight side and a structure side, and the vanes having a first continuously smooth, S-shaped surface extending from one end of the vane to an opposite end of the vane and a second continuously smooth, S-shaped surface extending from the end of the vane to the opposing end of the vane; a first light sensor disposed proximate the skylight side of the vanes for providing a signal over time representative of changing incident solar radiation at the skylight side of the vanes; a second light sensor disposed proximate the structure side of the vanes for providing a signal over time representative of changing incident solar radiation at the structure side of the vanes; and means operably connected to the vanes for automatically controlling the angle of each of the vanes in response to the signals of the first and second light sensors which signals vary due to changes in incident solar radiation over time.
