ABSTRACT:
An illuminating apparatus wherein light which is emitted by one or more projectors is divided into light beams by reflectors or lenses and is directed against the surface to be illuminated by an array of neighboring luminant spots in such a way that the eye of an observer looking at the spots from the surface to be illuminated is not affected by glare, that the surface is adequately illuminated, and that the eye can discern discrete luminant spots. This is accomplished by causing several light beams to impinge upon each unit area of the surface to be illuminated and by appropriate selection of the distance of the surface to be illuminated from the luminant spots as well as by appropriate selection of maximum dimensions of the spots and their mutual spacing in the array.
