Abstract

PURPOSE:To lead LED light efficiently to optical fibers and thus to improve reliability of a general ignition system by arranging a band fiber consisting of plural optical fibers along an optical axis of the beam of light emitted from LED. CONSTITUTION:One end of a bundling optical fiber 30 which corresponds to an LED luminous face is arranged along an optical axis 200 of the beam of light emitted from the luminous face and also arranged so as to correspond to the major part of the luminous face. The fiber 30 branches to plural fibers on the way, and the branching fibers correspond to a light receiving part of each light driving thyristor.
