Abstract
Description
上記構成によれば、主面に垂直に入射する光に平行な光であって、反射部に入射する光を反射部が傾斜端面に向けて反射する。従って、複数の光ファイバケーブルを主面に垂直な方向に出射するように配設することができ、光ファイバケーブルの曲げが不要なので、光ファイバケーブルの接続が容易になると共にコンパクトに接続することができる。
上記構成によれば、反射部を一定の傾斜角で平坦に形成できるので、傾斜端面における高い入射位置精度を確保し且つ高い反射率を有する反射部を形成することができる。従って、高い反射率の反射部で反射した光を高精度で受光部に入射させることができるので、光給電コンバータを大型化せずに複数の光ファイバケーブルから出射される光を受けて給電することができる。
光給電コンバータ1A〜1Cは、主面10aに垂直に入射した光と傾斜端面10c等に入射した光を受光部15に重ねて入射させ、受光部15で電流に変換して外部に供給する。従って、光給電コンバータ1A〜1Cを大きくすることなく、複数の光ファイバケーブルから出射される光を受けて給電することができる。
