LUMINOUS INTENSITY DISTRIBUTION CONTROL DEVICE, LUMINOUS FLUX DENSITY CONTROL DEVICE AND PARTITION METHOD

摘要

PROBLEM TO BE SOLVED: To reduce the shade or light quantity insufficient section by arranging a film-like or fabric transparent body having a number of protruding parts on the surface for diffusing, collecting and refracting light in a prescribed position of a building, and guiding the sunlight to the shade part or the like. ;SOLUTION: A flat or film-like transparent body 5 having a number of protruding part having circular, mountain-like, corrugated cross section on at least one side is set above two buildings 2. As the transparent body 5, a fabric having a number of monofilaments or bar bodies woven therein can be also used. The setting position of the transparent body 5 can be variously changed according to the form or arrangement of building and use. The diffused light or refracted light by the transparent body 5 is introduced to shade areas 3, 4 to significantly reduce the shade area. Further, the water surface of a culture pond or the like is covered with the transparent body 5 to enhance the lighting rate to the water, or the light can be converged to a solar battery panel to enhance the generating efficiency. Accordingly, sufficient light can be introduced to a light quantity insufficient section.;COPYRIGHT: (C)2000,JPO
