The device described consists of a vertically adjustable panel (6) to be mounted in an inclined position outside a window (14), meant to convey the daylight toward the ceiling of the room onto which the window opens, so as to diffuse this light toward the work surface from a direction almost equal to that of artificial light, and a multi-chamber refracting and reflecting diffusion screen (14), made up of a multitude of transparent glass hollow bars (16) or tubular elements, lying horizontally, the horizontal supporting base of which is sanded on the internal face. The bars (16) are placed one over the other up to the desired height in a rigid frame which is mounted to slide in front of the window pane, in a lower position than the adjustable panel (6). |
