20130120849 | OPTICAL PHASE SPACE COMBINER - An optical component called the Phase Space Combiner (PSC) is designed to join several bundles of rays. The bundles of rays, when represented in ray phase-space, occupy non-connected regions before passing through the PSC, while their representation in ray phase space occupies a single simply connected region (without holes) after passing through the PSC. Obviously, when used in reverse way it splits one bundle in several parts. We present herein the idea of using Multiple Individual Optics, MIO, not for collimating the light from the LEDs but as a PSC. Then a Single Common Optics, SCO, which can be an optical train, is used to get the desired intensity pattern. This hybrid SCO and MIO strategy combines most of the advantages of both approaches. | 05-16-2013 |
