Abstract: A multi input fiber optic apparatus for cooperating with a plurality of sources, the apparatus having output ends of the individual fiber optics disposed in a random pattern, wherein a dimension of the linear array is broken into sub-lengths and each sub-length has a number of input bundles corresponding to the number of inputs for the apparatus. The input bundles are randomized at the output ends within each sub-length. The apparatus includes a housing for supporting a plurality of randomized sub lengths disposed adjacent each other within the housing, wherein each sub length includes a plurality of sub-bundles, the number of sub-bundles equaling or corresponding to the number of sources, and a plurality of inputs optical connected to the sub lengths, each of the inputs including a sub-bundle from each sub-length.

Abstract: A light emitting panel backlighted by an optical fiber assembly is provided in which the individual optical fibers are positioned in parallel across the bottom of a frame and transverse notches are scored in the cladding so as to permit lateral emission of light along the length of the fibers. The lateral emissions impinge on an emitter and are projected onto a diffusing plate mounted in the top of the frame to provide uniform illumination throughout the entire area of the light emitting panel. Increased light throughput is obtained by inducing air flow at the end of the optical fiber bundle to keep the end surface cool by removing the heat from light energy impinging upon the end.
