ABSTRACT:
The Invention is a window blind with an integral, adjustable light shelf to control the entry of light into a room through a window. The blind may be a roller blind or any other suitable blind and controls entry of light through a lower portion of the window. The light shelf controls entry of light through an upper portion of the window and may be adjusted to reflect incident sunlight onto the ceiling of the room to provide indirect lighting to the room. The light shelf may be adjusted to substantially or partially exclude light from the room.
