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 through 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.
