LIGHT SOURCE SYSTEM WITH UNIFORMING DEVICE FOR OPTICAL FIBER TYPE LIGHTGUIDE

摘要

An optical system having a light source, a uniforming device and an optical fiber type lightguide, wherein the uniforming device comprises a first optical transmission portion connected to the lightguide and a second optical transmission portion connected to the first optical transmission portion including a plurality of optical fibers stretching across the inside thereof which are arranged in such a manner that a light-receiving end of each of the optical fibers is placed at a randomly assigned position on a light-receiving end of the second optical transmission portion and on the other hand a light-emitting end of each of the optical fibers is placed at a randomly assigned position on a light-emitting end of the second optical transmission portion, thereby uniforming the distribution of the quantity of light emitted therefrom.
