【発明の実施の形態】
(第1実施形態)
図1は本発明に係る第1実施形態の照明装置の構成図、図2は同照明装置の構造を示す図、図3は同照明装置用のリモコンを示す図、図4は同照明装置の制御部による制御内容の説明図である。
【0017】
第1実施形態の照明装置は、図2,図3に示すように、天井に取り付けられる照明器具本体1と、この照明器具本体1を覆うドーム状のシェード2とにより構成され、リモコン3が別に設けられるようになっている。
【0018】
照明器具本体1は、図1,図2に示すように、発光色の異なる複数種類(第1実施形態では2種類)の環状蛍光灯11A,11Bと、これら複数種類の環状蛍光灯11A,11Bをそれぞれ個別に点灯する複数の点灯回路部12A,12Bと、これらの入力側にそれぞれ設けられる複数のインターフェース13A,13Bと、リモコン3から所定操作による所定入力情報(コマンド)を受信するリモコン受信部14と、このリモコン受信部14で受信された入力情報に従って、複数のインターフェース13A,13Bを介して複数の点灯回路部12A,12Bを制御(例えば点滅または調光制御)することにより、複数種類の環状蛍光灯11A,11Bから放射される全光束および全放射光の色温度を連動させながら連続的に変化させる制御部10とを備えている。
【0019】
第1実施形態では、環状蛍光灯11Aには昼光色蛍光灯が使用され、環状蛍光灯11Bには電球色蛍光灯が使用される。
【0020】
そして、制御部10は、リモコン3から、全光束の増加(照度アップ)調節操作として「明」ボタン31を押す操作による入力情報をリモコン受信部14で受信すると、その入力情報に従って、上記全光束を連続的に増加させるとともに上記全放射光の色温度を連続的に高くする制御を実行する。また、制御部10は、リモコン3から、全光束の減少(照度ダウン)調節操作として「暗」ボタン32を押す操作による入力情報をリモコン受信部14で受信すると、その入力情報に従って、上記全光束を連続的に減少させるとともに上記全放射光の色温度を連続的に低くする制御を実行する。
【0021】
これらいずれの場合も、全光束とともに環状蛍光灯11A,11Bの各々の光束が調節制御される。つまり、全光束の変化に連動して、環状蛍光灯11A,11Bの光束値が個別に調節されるのであるが、第1実施形態では、図4に示すように、照度と色温度の変化に関する制御線に沿って、上記全光束および全放射光の色温度が連動して連続的に変化するように、制御部10による制御が実行される。図4に示す制御線は、照度[lx]を指数目盛、色温度[K]を等分目盛としたとき、制御直線L1となり、これは全光束(照度)と全放射光の色温度とを変数とする一次関数である。
【0022】
このように構成される照明装置では、「明」ボタン31を押す操作が行われ、その操作による入力情報がリモコン3から送信されてリモコン受信部14で受信されると、その入力情報に従って、照明装置の全光束および全放射光の色温度が連動して図4に示す制御直線L1に沿って連続的に右方に変化するように、制御部10が点灯回路部12A,12Bを制御する。これにより、照明装置の全光束および全放射光の色温度が図4に示す制御直線L1に沿って連続的に右方に変化する。
【0023】
一方、「暗」ボタン32を押す操作が行われ、その操作による入力情報がリモコン3から送信されてリモコン受信部14で受信されると、その入力情報に従って、照明装置の全光束および全放射光の色温度が連動して図4に示す制御直線L1に沿って連続的に左方に変化するように、制御部10が点灯回路部12A,12Bを制御する。これにより、照明装置の全光束および全放射光の色温度が図4に示す制御直線L1に沿って連続的に左方に変化する。
【0024】
第1実施形態によれば、点灯回路部12A,12Bを制御することにより、環状蛍光灯11A,11Bから放射される全光束および全放射光の色温度を連動させながら連続的に変化させるので、照明の演出範囲を限定することなく色温度を変化させることができる。
【0025】
また、全光束の調節入力情報に従って、全光束を連続的に変化させるとともに全放射光の色温度を連続的に変化させるので、照明に関する専門的な知識を必要とせずに、簡単な調節により色温度を変化させることができる。
【0026】
これらの効果は、少なくとも1つのコンセント受け部を電気スタンドに設けることにより確認することができる。
【0027】
(第2実施形態)
図5は本発明に係る第2実施形態の照明装置の制御部による制御内容の説明図である。
【0028】
第2実施形態の照明装置は、制御線が第1実施形態の制御線と相違する以外は第1実施形態の照明装置と同様に構成される。すなわち、第2実施形態の制御線は、照度[lx]を指数目盛、色温度[K]を等分目盛としたとき、図5に示すように、高照度ほど色温度の変化率の値が大きい制御曲線L2になっている。この制御曲線L2は、全光束(照度)と全放射光の色温度とを変数とし、n次関数またはn次関数の組合わさった関数である。
【0029】
このような第2実施形態でも、第1実施形態と同様の効果が得られる。
【0030】
(第3実施形態)
図6は本発明に係る第3実施形態の照明装置の制御部による制御内容の説明図である。
【0031】
第3実施形態の照明装置は、制御線が第1実施形態の制御線と相違する以外は第1実施形態の照明装置と同様に構成される。すなわち、第3実施形態の制御線は、照度[lx]を指数目盛、色温度[K]を等分目盛としたとき、図6に示すように、低照度ほど色温度の変化率の値が大きい制御曲線L3になっている。この制御曲線L3は、全光束(照度)と全放射光の色温度とを変数とし、n次関数またはn次関数の組合わさった関数である。
【0032】
このような第3実施形態でも、第1実施形態と同様の効果が得られる。
【0033】
(第4実施形態)
図7は本発明に係る第4実施形態の照明装置の制御部による制御内容の説明図である。
【0034】
第4実施形態の照明装置は、制御線が第1実施形態の制御線と相違する以外は第1実施形態の照明装置と同様に構成される。すなわち、第4実施形態の制御線は、図7に示すように、高照度ほど色温度の変化率の値が大きい制御曲線L4になっている。この制御曲線L4は、照度と色温度の変化に関する官能評価により導かれたものである。官能評価項目のうち、「落ち着く」と「爽やか」に関して指標とし、低照度・低色温度領域においては「落ち着く」評価が有意に高い部分に制御曲線L4を設定し、高照度・高色温度領域においては「爽やか」評価が有意に高い部分に制御曲線L4が重なるように設定してある。そして、それらのポイントを滑らかにつないだ曲線を制御曲線L4に設定してある。
【0035】
このような第3実施形態でも、第1実施形態と同様の効果が得られる。また、照度と色温度の変化に関する官能評価により導かれた「落ち着き」と「爽やか」の領域をトレースするように、照明装置の全光束および全放射光の色温度を連動させながら連続的に変化させるので、使う人にとって心地よい照明空間を簡単に提供できる。
【0036】
なお、上記各実施形態では、複数の光源として環状蛍光灯11A,11Bが使用される構成になっているが、これに限らず、複数の光源のうち少なくとも1つの光源は、白熱電球、直管蛍光灯、発光ダイオード、または発光ダイオードの集合体である構成でもよい。

In the first embodiment, a daylight fluorescent lamp is used as the annular fluorescent lamp 11A, and a bulb fluorescent lamp is used as the annular fluorescent lamp 11B.
[0020]
Then, when the remote controller 3 receives, from the remote controller 3, input information on the operation of pressing the “bright” button 31 as an operation for increasing the total luminous flux (increase of illuminance), the remote controller receiver 14 receives the input information based on the input information. And the color temperature of the total emitted light is continuously increased. Further, when the remote controller 3 receives, from the remote controller 3, the input information of the operation of pressing the “dark” button 32 as the adjustment operation of the total luminous flux reduction (illuminance down), the remote control receiver 14 receives the input information according to the input information. And the color temperature of the total emitted light is continuously reduced.
[0021]
In each case, the luminous flux of each of the annular fluorescent lamps 11A and 11B is adjusted and controlled together with the total luminous flux. That is, the luminous flux values of the annular fluorescent lamps 11A and 11B are individually adjusted in conjunction with the change of the total luminous flux. However, in the first embodiment, as shown in FIG. The control by the control unit 10 is performed such that the color temperature of the total light flux and the total radiation light continuously changes in conjunction with the control line.
