ABSTRACT:
A fiber optics illuminator is described consisting of a light bulb having a fiber optics coupler or coupling means integral with the bulb envelope. The bulb is provided with a combination of ellipsoidal and spherical mirrors which together direct all light emitted from the filiment through a small optical window located at the rear of said coupler or coupling means. To facilitate trapping of the light in the optical fibers, the light is made to emerge from the optical window at angles equal to or less than the critical angle of the fibers. This invention is intended for use as a primary light source for most applications involving illumination wherein visible or infra-red or ultraviolet electromagnetic radiation is channeled by optical fibers to illuminate a specific environment.
