ABSTRACT:
An apparatus for controlling energy from a skylight of a structure including a plurality of vanes positioned beneath the skylight and angularly adjustable to control solar radiation entering the structure through the skylight. The vanes are substantially S-shaped. A first light sensor is 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, and a second light sensor disposed proximate the structure side the vanes for providing a signal over time representative of changing incident solar radiation at the structure side of the vanes. A control assembly is 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. A light deflecting member is positioned below the vanes a selected distance so as to cause a first portion of the light that passes through the vanes to be reflected toward the ceiling of the structure and a second portion of the light to pass directly toward the floor of the structure.
