Abstract

A converter plate includes an array of optical fibers arranged axially parallel to each other. The optical fibers have optical properties selected to convert light from a light-emitting diode entering the optical fibers from one end of the array of optical fibers to light of a different wavelength exiting the fibers from another end of the array of optical fibers. The optical properties of some of the optical fibers differ from the optical properties of others of the optical fibers such that the light exiting the some of the optical fibers has a wavelength different from that of the light exiting the others of the optical fibers. The converter plate is manufactured by providing the optical fibers and combining the optical fibers into a bundle, the optical fibers being arranged axially parallel to each other. The bundle of optical fibers is drawn to attenuate the bundle of fibers into a secondary fiber having a reduced cross section. The secondary fiber is wafered into a converter plate that includes an array of the optical fibers arranged axially parallel to each other.
