Abstract
Abstract A centralized lighting system having a plurality of output ports includes a high brightness light source disposed at the optical focal point of a parabolic reflector. The light source and reflector configuration deliver light output in an essentially parallel manner to a plurality of lens members effective for focussing the light output into a plurality of spatially separate light spots. The spatially separate light spots are input to optical fibers without experiencing packing fraction losses. The plurality of lens members are disposed equidistantly along radii formed relative to the reflector but at a spaced apart relation to the reflector. In this manner, the lens members provide the spatially separate light spots which are essentially equal in terms of color and intensity to one another.
