| Title: |
LED Luminance-Enhancement and Color-Mixing by Rotationally Multiplexed Beam-Combining |
| Abstract: |
The present embodiments provide methods and systems for use in providing
enhanced illumination. Some embodiments include at least two light
sources and one or more smoothly rotating wheels, where the one or more
wheels comprises at least one mirror sector, the circumferential portion
of the mirror sector is the inverse of the number of said sources, a
first source of the sources is so disposed that the mirror sector
