具体的には、100人の被験者に、LED光源による単色光(半値幅20~40nm)の緑色光を照射した場合に睡眠誘導効果が得られた者は40人弱であったが、半値幅10ナノメートル以下の超狭帯域な緑色光を所定の照度で顔の眼の位置に照射した場合に、睡眠誘導効果が得られた者は60人以上であった。
ここで、青色光の場合、特に、50~250ルクスの範囲に調整するのが好ましいという知見を実験により得ている。
超狭帯域光照射手段は、
ピーク波長域が430nm~500nmであって、半値幅10nm以下の青色の超狭帯域光を発生させる第1超狭帯域光照射手段、
ピーク波長域が500nm~550nmであって、半値幅10nm以下の緑色の超狭帯域光を発生させる第2超狭帯域光照射手段、
第1超狭帯域光照射手段と第2超狭帯域光照射手段とを切り替える光源切替手段と、
光源切替手段に切り替え信号を出力する制御手段と、
を更に備える構成とされる。
上記の制御手段は、第1の超狭帯域光照射手段と第2の超狭帯域光照射手段に所定の時間間隔をあけて、交互に出力信号を出すのが好ましい。緑色、青色それぞれのLEDから発生する光を交互に顔全体に照射することで深い睡眠へと導いていけるからである。所定時間は1分程度であり、全体では、約10分程度で睡眠誘導効果が現れる。
ここで、光量の減衰を最小限に抑える観点から拡散レンズが好適に用いることができる。
なお、シリンドリカルレンズを拡散手段に用いて、さらに拡散レンズ、拡散板などを併用してもかまわない。
すなわち、上記の本発明の安眠誘導装置を病室の照明に用い、患者ベッドに横たわる患者の顔の付近の照度を調整して、就寝時刻後に患者を安眠させるのである。就寝時刻後に消灯するのはなく、青~緑の光を照らすことにより、ベッドの周囲の見通しがよくなり、安全性も向上する。
また、寝具用ベッドに取り付ける場合は、超狭帯域光照射手段に通常のスタンド型照明と同様にハウジングで超狭帯域光の照射範囲を制御することも可能である。患者の顔の部位にのみ照射させることで、電気をつけた状態や昼間の明るい状況においても、患者を安眠に誘導できるのである。
本発明の安眠誘導方法は、ピーク波長域が430~550nmであって、半値幅10nm以下の青色~緑色の超狭帯域光を、拡散させて人の顔全体に照射し、かつ、顔の眼の位置における照度を20~250ルクスに調整するものである。
かかる方法によれば、優れた睡眠誘導効果が得られる。
第1超狭帯域光は、ピーク波長域が430nm~500nmであって半値幅10nm以下の青色の超狭帯域光であり、第2超狭帯域光は、ピーク波長域が500nm~550nmであって、半値幅10nm以下の緑色の超狭帯域光である。
かかる方法によれば、強い睡眠誘導効果を有する青色の超狭帯域光と、リラックスでき睡眠誘導効果を有する緑色の超狭帯域光を、交互に使用して、睡眠誘導を穏やかに行うことができる。
安眠誘導装置1は、青色~緑色の特定波長の超狭帯域光20を所定の照度範囲で人の顔21全体に照射することで、睡眠誘導させるものである。
安眠誘導装置1は、筒状本体2の底部に取り付けられた半値幅が20nm~40nmの青色もしくは緑色のLED光源7と、LED光源7から出射された光の波長帯域を絞るバンドパスフィルター13と、バンドパスフィルター13を透過した半値幅が10nm以下の超狭帯域の光を拡散させる拡散レンズ12から構成される。LED光源7は、ON/OFF信号と電源は、信号・電源ケーブル14を介して供給される。バンドパスフィルター13と拡散レンズ12は筐体フレーム15に取り付けられており、筒状本体2と脱着可能になっている。バンドパスフィルター1を取り替えることにより、所望の半値幅の超狭帯域の光を作り出すことができる。また、拡散レンズ12を取り替えることにより、照射面積を調整することができる。
また、安眠誘導装置1に照度センサーを内蔵させて、顔表面にミラーを置き、ミラーで反射した光を安眠誘導装置1に内蔵した照度センサーで計測させて、自動的に超狭帯域光の光源の強度を調整させることも可能である。
以下に説明する実施例の測定に用いた照度計は、TOPCOM(登録商標)照度計IM-5である。
青色の超狭帯域光は、中心波長(ピーク波長)が460nmであり、半値幅が10nmである。また、緑色の超狭帯域光は、中心波長(ピーク波長)が530nmであり、半値幅が10nmである。
