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 reflects light from the first source into a common output path, where the first source pulsing such that a duty cycle of the first source corresponds to a time the mirror sector reflects light from the first source into the common output path.
