OPTICAL FIBER LIGHTING DEVICE AND METHOD

摘要

A lighting device is provided that includes a plurality of laser diodes (14A-14C) each producing light in respective beams and a plurality of collimating lenses (22A-22C) optically aligned with respective beams of the plurality of laser diodes. The lighting device also includes a field lens (24) optically aligned to receive the laser light emitted by each of the plurality of laser diodes and directed thereto by the plurality of collimating lenses. The lighting device further has a light diffusing fiber (30) having a terminal end located near a focal point of the field lens to receive the laser light, wherein the light diffusing fiber emits light from a side wall.
