ABSTRACT:
An illumination system includes an artificial radiant source that emits energy in the visible and infrared regions of the spectrum. A radiation splitter splits the majority of the visible energy from the majority of the infrared energy to form an illumination beam and a heating beam. A light conductor conducts portions of the visible light to at least one area to be illuminated, and a heat recovery system recovers energy from the heating beam and provides it at an energy output. A solar collector may direct a solar beam on the radiation splitter to supplement the artificial source beam. A supporting portion may support a lighting fixture. An artificial illumination source is placed at a position that is unsupported by the supporting portion, and a light conductor provides an optical path for radiation produced by the source to the fixture.
