PROBLEM TO BE SOLVED: To provide an apparatus for lighting a plurality of separate illumination elements by using a single light source to achieve saving of electrical energy, reduction of running cost, and elimination of short circuit or electric leakage. SOLUTION: The light of a single light source is divided into a plurality of optical fibers. The light is transferred through branched wave-guides to the leading ends of the optical fibers providing illumination. |
