Claims (9)
- 照射開口部とこの照射開口部に対向する反射面を有する器具本体と、
前記照射開口部から直接光が出射され、かつ、前記反射面に直接光が照射されないように前記照射開口部に対向して前記器具本体に配置されたLEDからなる複数の点光源と、
前記器具本体に配置され、前記点光源の点灯時、前記点光源の近傍の反射面を直接照射する、指向性を有するLEDからなる第2の光源と、
前記点光源及び前記第2の光源を点灯制御する点灯回路と、
を具備したことを特徴とする照明器具。 - 前記第2の光源を照射開口部側から視認されないようにする遮蔽部を備え、点光源としてのLEDは複数配設され、光軸がこのLEDの間になるように前記第2の光源が配設されたことを特徴とする請求項1記載の照明器具。
- 前記点光源は前記器具本体に複数が所定間隔を有して配設され、前記所定間隔を有して配設された複数の点光源は中央部にいくに従って光出力が小さく設定され、前記第2の光源は前記複数の点光源の周囲から前記複数の点光源が配設される領域の中央部に向かって前記点光源の近傍を照射することを特徴とする請求項1または2記載の照明器具。
- 前記点光源の出射光が照射される領域と前記第2の光源から照射した光が前記点光源の近傍で反射した反射光が照射される領域とが重なっていることを特徴とする請求項1ないし3のいずれか一記載の照明器具。
- 前記点光源のLEDが配設される基板の表面は拡散性を有する反射面であることを特徴とする請求項1ないし4のいずれか一記載の照明器具。
- 前記第2の光源の1つが少なくとも隣接する2つの前記点光源の近傍を照射することを特徴とする請求項1ないし5のいずれか一記載の照明器具。
- 前記点光源の配置間隔よりも前記第2の光源の配置間隔の方がより密になっていることを特徴とする請求項1ないし6のいずれか一記載の照明器具。
- 前記点灯回路は、入力される調光信号が所定の調光度以上のときは前記点光源のみを調光し、入力される調光信号が所定の調光度未満のときは前記点光源を消灯し、かつ、前記第2の光源を調光することを特徴とする請求項1ないし7のいずれか一記載の照明器具。
- 前記点灯回路は、入力される調光信号の調光度に対し、前記第2の光源の光出力の変化率が前記点光源の光出力の変化率よりも小さくなるように調光することを特徴とする請求項1ないし7のいずれか一記載の照明器具。
