Illumination system using filament lamps
First Claim
1. An illumination system using filament lamps comprising:
- a filament lamp;
a first reflector structure having a first reflector portion with a first focal point, and second reflector portion with a second focal point;
said filament lamp disposed proximate to said first focal point of said first reflector structure to emit rays of electromagnetic radiation that reflect from said first reflector portion to said second reflector portion and then converge substantially at said second focal point;
wherein a portion of the electromagnetic radiation emitted by said filament lamp impinges directly on said first reflector structure and a portion of the electromagnetic radiation does not impinge directly on said first reflector structure and wherein said system further comprises an additional reflector constructed and arranged to reflect at least part of the portion of the electromagnetic radiation that does not impinge directly on said first reflector structure toward said first reflector structure.

Abstract
An illumination system using filament lamps including a filament lamp, a reflector having a first and second focal points, the filament lamp disposed proximate to the first focal point of the reflector to emit rays of electromagnetic radiation that reflect from the reflector and converge substantially at the second focal point, wherein a portion of the electromagnetic radiation emitted by the filament lamp impinges directly on the reflector and a portion of the electromagnetic radiation does not impinge directly on the reflector and wherein the system further includes an additional reflector constructed and arranged to reflect at least part of the portion of the electromagnetic radiation that does not impinge directly on the reflector toward the reflector through the first focal point of the reflector.

28. A method of illumination comprising the steps of:
-
positioning a filament lamp at a first focal point of a first reflector structure;
producing rays of radiation by said filament lamp;
reflecting a portion of said rays of radiation by said first reflector structure toward a second focal point, wherein said first reflector structure has a first reflector portion with said first focal point, and a second reflector portion with said second focal point, wherein said rays reflect from said first reflector portion to said second reflector portion and then said rays converge substantially at said second focal point;
reflecting at least part of a portion of the rays of radiation that do not impinge directly on said first reflector structure toward said first reflector structure;
positioning an output light pipe having an input surface and an output surface so said input surface is substantially proximate to said second focal point;
collecting said rays of radiation at said input surface;
passing said rays of radiation through said output light pipe; and
outputting rays of radiation from said output surface of said output light pipe. - View Dependent Claims (29, 30, 31, 32, 33, 35, 37)
