Device for controlling the light intensity distribution, an apparatus for controlling the light flux density and division method

摘要

A luminous intensity distribution control device and a luminous flux density control device capable of applying sufficient rays of light to shadowed or poorly illuminated regions or portions because of structures and other objects by means of luminous intensity distribution control or luminous flux density control including light diffusion, refraction and splitting, wherein sunbeams are diffused by transparent bodies installed above two buildings and allowed to reach regions or portions that have conventionally been shadowed.
