PURPOSE: A blind for lighting is provided to allow more sunlight to penetrate deeply to an interior space by individually regulating the angles of slats installed in three stages. CONSTITUTION: A blind for lighting comprises a first frame(10), slats(30), a bottom bar(20), a tilting line(40), an elevation control line(70), and an angle control unit. The first frame is fixed to a ceiling. The slats are arranged at regular intervals in a vertical direction under the first frame and installed in three stages by being in contact with each other in a back-and-forth direction. The bottom bar is located at the bottom of the slats in order to make the slats spread down. The tiling line comprises two or more horizontal ropes(42a~42c) supporting the bottoms of the slats and four vertical ropes(41a~41d) which are connected to the horizontal ropes and vertically placed between the adjacent slats. The tops of the vertical ropes are located inside the first frame. One side of the elevation control line is located inside the first frame and passes through the slats while the other side is connected to the bottom bar so that the slats and the bottom bar can be moved up and down using the elevation control line. The angle control unit controls the slope of each slat to regulate the amount and reflective direction of light penetrating through a window. |
