MULTIPLE-PORT HIGH-BRIGHTNESS CONCENTRATING ILLUMINATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a centralized lighting system having a plurality of output ports whose light outputs are identical for improved packing fraction characteristic. SOLUTION: Light output is delivered in an essentially parallel manner to a plurality of lens members 16, 18 from a light source-reflecting member assembly having a high brightness light source 12 disposed at the optical focal point of a parabolic reflecting member 14 and is focused into a plurality of spatially separate light spots by the plurality of lens members. The spatially separate light spots are input to optical fibers 22 without experiencing packing fraction losses. The plurality of lens members are disposed equidistantly along radii formed relative to the reflecting member and in a spaced relation to the reflecting member, so that the lens members provide the spatially separate light spots which are equal in terms of color and intensity to one another.
