TLDR
In this paper, a light box contains at least one surface of an optically diffuse plate, which is subjected to light from within in the region of the desired light field, and the surface of a diffusely reflecting plate is arranged in the light box at a distance from and parallel to the diffuse plate.Abstract:
The light box (10) contains at least one surface of an optically diffuse plate (15) which is subjected to light from within in the region of the desired light field. The surface of a diffusely reflecting plate (17) is arranged in the light box at a distance from and parallel to the diffuse plate essentially corresponding to a surface of the desired light field.The facing surfaces of the diffuse plate and diffusely reflecting plate are associated with sections (16a,16b) of transparent foil with one smooth side and a prismatic structure on the other. The foil sections are oriented so that their prismatic structures lie parallel and facing one or other plate. At least one rod-shaped light source emits light laterally into the space between the foil sections in the prism direction.read more
