Abstract
Each light slat of the Mini-Optical Light Shelf daylighting system consists of a light reflecting segment that comprises the top surface of the light slat. A light shading segment and a light redirecting segment comprise the bottom surface of the light slat. The daylight incident on the daylight collection section of the glazing is collected by the optically shaped light reflecting segment of the light slats and redirected onto the ceiling plane of the room in a glare free, uniform manner. In addition, the light redirecting segment of each light slat functions to redirect incident daylight, that is reflected off the light reflecting segment of the adjacent light slat at angles above a predetermined threshold, onto the ceiling plane of the room. The light shading segment functions to block low altitude components of incident daylight from entering the room.
