PROBLEM TO BE SOLVED: To control transmitted light by rockably suspending multiple shielding sheets from a translucent roof, and feeding cross air flow to the faces of the shielding sheets to change the suspension angles of the shielding sheets. SOLUTION: Rings are fitted to the tips of shielding sheets 5 made of a fabric, the rings are hooked on a rocking shaft provided on a support rod 11, and the shielding sheets 5 are arranged on a circular translucent roof. Cross air flow 7 is fed to the faces of the shielding sheets 5 suspended from the support rod 11 by a blast device constituted of a blower 6 and a duct, then the shielding sheets 5 are pushed by the air flow 7 and are shifted from the vertical state to the inclined state to shield sunlight 2, and the blowout position and blowout angle are adjusted by the duct. The load applied to a roof is reduced, resources can be saved, and uniform sunlight collection can be made. |
