Abstract:
1. An illumination system using filament lamps comprising: a first reflector comprising a first reflector portion with a first focal point, and second reflector portion with a second focal point; a filament lamp comprising a filament, disposed proximate to said first focal point of said first reflector, for emitting rays of electromagnetic radiation that reflect from said first reflector portion and said second reflector portion to converge substantially at said second focal point of said second reflector portion; a second reflector arranged to reflect at least part of a portion of the electromagnetic radiation that does not impinge directly on said first reflector toward said filament lamp; and wherein said filament substantially blocks and absorbs said portion of the electromagnetic radiation, thereby heating said filament of said filament lamp to increase said electromagnetic radiation output of said filament lamp.
