摘要： Method, devices and systems are disclosed which provide for the indirect, substantially glare-free, directional lighting of three-dimensional objects, by which artificial light is generated at a central point which is recessed, in close proximity to, and below the object to be illuminated, said light being directed downwardly against a reflective surface and then upwardly in the direction of such object in the shape of a predetermined light mantle substantially enveloping the object without significant scattering of light. Shielding means above the light source protect the eyes of observers from direct view of the light. The upwardly reflected light is centripetally and indirectly visible without glare by its reflections from the illuminated object. The disclosed arrangement of components permits multi-directional centripetal viewing, including particularly the glare-free viewing by a plurality of observers, for instance persons grouped around the illuminated object in a circle, irrespective of the direction of the light source relative to the eyes of observers.
