Claims (1)
- 指標を指示する棒状の指針先端部、及び、入射面から入射された光を前記指針先端部側に反射する反射面が設けられた前記指針先端部よりも幅広の指針後端部、から構成された指針部材と、前記指針部材の回転軸を囲むように配置されていて前記指針部材の入射面に入射する光を出射する複数の光源と、を備え、前記指針部材の回転軸よりも先端側及び後端側の両側に前記反射面が設けられ、前記指針部材の全回転範囲において複数の光源全部からの光が前記指針部材の反射面で反射される指針照明装置において、
前記光源の中心軸から出射される光が前記反射面において前記指針先端部の中心軸と重なる位置で反射されるとき輝度が最小となり、前記光源の中心軸から出射される光の前記反射面での反射位置が前記指針先端部の中心軸と重なる位置から離れるに従って輝度が大きくなるように、前記指針部材の回転に応じて前記光源の輝度を制御する輝度制御手段を
有することを特徴とする指針照明装置。
