Abstract
A system including a rotationally static light emitting material with rotating optics is provided. The system comprises: the material on a heatsink being circularly symmetrical around an axis, and rotationally fixed; a stationary light source configured to generate excitation light, the excitation light configured to excite the material producing emitted light, an incoming path of the excitation light forming a first angle, with the axis greater than 0° and less than 90°; and, optics, configured to rotate relative to the material around the axis, comprising: a first mirror on the axis and forming a second angle with the axis greater than 0° and less than 90°, the first mirror located on the incoming path; and a second mirror parallel to the first mirror, the first mirror configured to reflect the excitation light towards the second mirror, and the second mirror configured to reflect the excitation light towards the material.
