Abstract
A system including rotationally static light emitting material with rotating optics is provided. The system comprises: a heatsink; at least one light emitting material on the heatsink, at least a portion of the light emitting material being circularly symmetrical around an axis, the heatsink and the light emitting material being rotationally fixed; optics configured to rotate relative to the at light emitting material around a rotational axis that is coaxial with the axis of the light emitting material, the optics configured to: receive excitation light along the rotational axis; convey the excitation light to one or more locations on the light emitting material as the optics are rotating; collect light emitted from the one or more locations on the light emitting material excited by the excitation light; and, convey the light collected from the at least one light emitting material to the rotational axis for emission there along.
