Abstract: Devices and methods 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 the object to be illuminated. Said light enters light-conductive means throught an optical interface and is conducted towards and projected in the direction of such object in the shape of a predetermined light beam or mantle substantially enveloping or highlighting selected surfaces of the object without significant scattering of light. Shielding means protect the eyes of observers from direct view of the light source. The arrangement of components permits multi-directional, centripetal, substantially glare-free viewing by a plurality of observers grouped around the illuminated object.

Abstract: Three dimensional objects such as plants, are illuminated with indirect, substantially glare-free, directional lighting. Artificial light is generated at a central point which is recessed in close proximity to and below the objects to be illuminated. The light enters light-conductors through an optical interface and is conducted towards and projected in the direction of the interior of the foliage of plants or of other objects. The light is reflected from such objects thereby creating substantially glare-free viewing from any position around the illuminated object.

Abstract: 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.
