　［光源部の制御］
　次に、照明器具１０における光源部１１の光源光の発光状態の制御について説明する。 [Control of light source]
Next, the control of the light emitting state of the light source light of the light source unit 11 in the luminaire 10 will be described.
　照明器具１０は、電力が供給されると、光源制御部１２による制御に基づいて光源部１１の複数の光源が発光する。 When power is supplied to the luminaire 10, a plurality of light sources of the light source unit 11 emit light based on control by the light source control unit 12.
　光源制御部１２は、第１光源１１ａ、第２光源１１ｂ、第３光源１１ｃ及び第４光源１１ｄへの電流量を個別に調整し、第１光源１１ａ、第２光源１１ｂ、第３光源１１ｃ及び第４光源１１ｄそれぞれの光量を時間的に変化させることで、光源光を調光及び調色する。これにより、光源光の発光状態が時間的に変化するように、光源部１１が光源制御部１２に制御される。なお、光源制御部１２は、目的の光色によって、電力を供給させない光源があってもよい。光源制御部１２は、第１照明シーンと第２照明シーンとを切り替えるように光源部１１を制御する。 The light source control unit 12 individually adjusts the amounts of current to the first light source 11a, the second light source 11b, the third light source 11c, and the fourth light source 11d, and adjusts the amounts of current to the first light source 11a, the second light source 11b, the third light source 11c, and the fourth light source 11d. The light source light is dimmed and toned by changing the amount of light of each of the fourth light sources 11d with time. As a result, the light source unit 11 is controlled by the light source control unit 12 so that the light emission state of the light source light changes with time. The light source control unit 12 may have a light source that does not supply electric power depending on the target light color. The light source control unit 12 controls the light source unit 11 so as to switch between the first lighting scene and the second lighting scene.
　ここで、第１照明シーン及び第２照明シーンについて、詳細に説明する。 Here, the first lighting scene and the second lighting scene will be described in detail.
　図３及び図４は、光源部１１が発する光源光の発光状態の時間変化の例を示す図である。図３及び図４に示されるように、光源制御部１２は、第１照明シーンと第２照明シーンとを切り替えるように光源部１１を制御する。光源制御部１２は、例えば、第２照明シーンにした後に、第１照明シーンに切り替えるように光源部１１を制御する。 3 and 4 are diagrams showing an example of the time change of the light emitting state of the light source light emitted by the light source unit 11. As shown in FIGS. 3 and 4, the light source control unit 12 controls the light source unit 11 so as to switch between the first lighting scene and the second lighting scene. The light source control unit 12 controls the light source unit 11 so as to switch to the first lighting scene after the second lighting scene, for example.
　第１照明シーンは、ユーザにリラックスを促す照明シーンである。具体的には、図３及び図４に示されるように、第１照明シーンでは、光源制御部１２は、光源光の発光状態を、第１発光状態と第１発光状態よりも刺激純度及び光量の少なくとも一方が小さい第２発光状態との間で、第１周期で反復して変化させるように光源部１１を制御する。このように、第１照明シーンでは、光源光の刺激純度及び光量のうち少なくとも一方を一定の周期で連続的に変動させて、一定の周期でユーザに呼吸をするように誘導する。これにより、ユーザにリラックスを促すことができる。 The first lighting scene is a lighting scene that encourages the user to relax. Specifically, as shown in FIGS. 3 and 4, in the first lighting scene, the light source control unit 12 sets the light source light emission state to be more stimulating purity and light intensity than the first light emission state and the first light emission state. The light source unit 11 is controlled so as to repeatedly change in the first cycle from the second light emitting state in which at least one of the two is small. As described above, in the first lighting scene, at least one of the stimulus purity and the amount of light of the light source is continuously changed at a fixed cycle to induce the user to breathe at a fixed cycle. This can encourage the user to relax.
　第２発光状態は、第１発光状態よりも、刺激純度のみが小さい発光状態であってもよく、光量のみが小さい発光状態であってもよく、刺激純度及び光量のいずれもが小さい発光状態であってもよい。これらの中でも、発光状態の変化量を増やしてユーザに呼吸を誘導する効果を高める観点からは、第２発光状態は、第１発光状態よりも刺激純度及び光量のいずれもが小さい発光状態であってもよい。なお、図３及び図４に示される例では、第１発光状態及び第２発光状態の刺激純度及び光量は、時間と共に変化していないが、第２発光状態が、第１発光状態の刺激純度及び光量以上にならない範囲で変化してもよい。また、第１発光状態から第２発光状態への刺激純度及び光量の変化は、図示されるような線形的な変化だけでなく、指数関数的な変化、又は、ステップ状の変化等であってもよい。 The second light emitting state may be a light emitting state in which only the stimulation purity is smaller than that in the first light emitting state, or may be a light emitting state in which only the amount of light is smaller, and the light emitting state in which both the stimulation purity and the amount of light are smaller. There may be. Among these, from the viewpoint of increasing the amount of change in the light emitting state and enhancing the effect of inducing respiration to the user, the second light emitting state is a light emitting state in which both the stimulation purity and the amount of light are smaller than those of the first light emitting state. You may. In the examples shown in FIGS. 3 and 4, the stimulation purity and the amount of light in the first light emitting state and the second light emitting state do not change with time, but the second light emitting state is the stimulation purity in the first light emitting state. And may change within a range that does not exceed the amount of light. Further, the change in the stimulus purity and the amount of light from the first light emitting state to the second light emitting state is not only a linear change as shown in the figure, but also an exponential change, a step-like change, or the like. May be good.
　第１発光状態と第２発光状態との刺激純度及び光量の差は、ユーザの属性、照明器具１０が設置される環境等に応じて、ユーザが発光状態の変化を認識できる程度以上に設定される。 The difference in stimulus purity and light intensity between the first light emitting state and the second light emitting state is set to a extent that the user can recognize the change in the light emitting state according to the attributes of the user, the environment in which the lighting fixture 10 is installed, and the like. NS.
　光源制御部１２は、例えば、光源光の刺激純度を小さくしていく場合、光源部１１を構成する複数の光源のうち、刺激純度の高い光源の光量を減らしていくと同時に、刺激純度の低い光源の光量を増やしていくように制御する。また、光源光の刺激純度を大きくしていく場合には、刺激純度を小さくする場合と逆の制御を行う。 For example, when the stimulus purity of the light source light is reduced, the light source control unit 12 reduces the amount of light of the light source having a high stimulus purity among the plurality of light sources constituting the light source unit 11, and at the same time, the stimulus purity is low. Control to increase the amount of light from the light source. Further, when increasing the stimulation purity of the light source light, the control opposite to the case of decreasing the stimulation purity is performed.
　光源制御部１２は、図３に示されるように、第２発光状態で第１照明シーンを開始するように光源部１１を制御してもよく、図４に示されるように、第１発光状態で第１照明シーンを開始するように光源部１１を制御してもよい。また、光源制御部１２は、第１発光状態と第２発光状態の間の刺激純度及び光量の発光状態で第１照明シーンを開始するように光源光を制御してもよい。 The light source control unit 12 may control the light source unit 11 so as to start the first lighting scene in the second light emitting state as shown in FIG. 3, and the light source control unit 12 may control the light source unit 11 so as to start the first lighting scene in the second light emitting state. The light source unit 11 may be controlled so as to start the first illumination scene. Further, the light source control unit 12 may control the light source light so as to start the first illumination scene in the light emitting state of the stimulus purity and the amount of light between the first light emitting state and the second light emitting state.
　第１周期は、後述する動作例で説明するように、操作器２０のユーザの操作等に基づいて決定されてもよいが、あらかじめ設定されていてもよい。第１周期があらかじめ設定されている場合、第１周期は、例えば、周波数が４．５ｃｙｃｌｅ／ｍｉｎ以上７ｃｙｃｌｅ／ｍｉｎ以下の周期である。このような第１周期は、人の血圧の変動の周期と同程度であり、この第１周期に合わせてユーザの呼吸を誘導することで、ユーザの心拍変動にメリハリがつき、ユーザのリラックス度を高めることができる。 The first cycle may be determined based on the operation of the user of the actuator 20 or the like, as will be described in the operation example described later, but may be set in advance. When the first cycle is preset, the first cycle is, for example, a cycle having a frequency of 4.5 cycles / min or more and 7 cycles / min or less. Such a first cycle is about the same as the cycle of fluctuations in a person's blood pressure, and by inducing the user's breathing in accordance with this first cycle, the user's heart rate variability becomes sharp and the user's degree of relaxation Can be enhanced.
　また、図３及び図４に示されるように、例えば、第１周期内での、第２発光状態から第１発光状態へ変化する時間Ｔ１は、第１発光状態から第２発光状態へ変化する時間Ｔ２よりも短い。つまり、第２発光状態から第１発光状態へ変化する速度が、第１発光状態から第２発光状態へ変化する速度よりも速い。このように、刺激純度及び光量の少なくとも一方が比較的大きい第１発光状態への変化を速くすることで、ユーザが発光状態の変化に気づきやすくなり、ユーザが呼吸をするようにより誘導しやすくなる。また、時間Ｔ１と時間Ｔ２との比率は、例えば、およそ４：６である。ユーザを、この比率に合わせた呼気と吸気との呼吸に誘導することで、呼気より吸気が適度に長くなるため、よりユーザのリラックス度を高めることができる。なお、時間Ｔ１と時間Ｔ２とは同じであってもよく、時間Ｔ１の方が時間Ｔ２よりも長くてもよい。 Further, as shown in FIGS. 3 and 4, for example, the time T1 during the first cycle of changing from the second light emitting state to the first light emitting state changes from the first light emitting state to the second light emitting state. Shorter than time T2. That is, the speed at which the second light emitting state changes to the first light emitting state is faster than the speed at which the first light emitting state changes to the second light emitting state. In this way, by accelerating the change to the first luminescence state in which at least one of the stimulus purity and the amount of light is relatively large, the user can easily notice the change in the luminescence state, and the user can be more easily guided to breathe. .. The ratio of time T1 to time T2 is, for example, about 4: 6. By inducing the user to breathe between exhalation and inspiration according to this ratio, the inspiration becomes moderately longer than the exhalation, so that the degree of relaxation of the user can be further enhanced. The time T1 and the time T2 may be the same, and the time T1 may be longer than the time T2.
　第２照明シーンは、ユーザを知的作業に集中させる照明シーンである。具体的には、図３及び図４に示されるように、第２照明シーンでは、光源制御部１２は、例えば、光源光の発光状態、つまり、刺激純度（より具体的には色度）及び光量を一定にするように光源部１１を制御する。第２照明シーンにおける光源光の発光状態は、図３に示されるように、第１照明シーンにおける第２発光状態の刺激純度及び光量であってもよく、図４に示されるように、第１照明シーンにおける第２発光状態の刺激純度及び光量より大きい発光状態であってもよい。また、第２照明シーンにおける光源光の発光状態は、第１照明シーンにおける第２発光状態の刺激純度及び光量より小さい発光状態であってもよい。また、第１照明シーンと第２照明シーンとで、光源光の色度は同じであってもよく、異なっていてもよい。 The second lighting scene is a lighting scene that concentrates the user on intellectual work. Specifically, as shown in FIGS. 3 and 4, in the second lighting scene, the light source control unit 12 has, for example, the light source light emission state, that is, the stimulus purity (more specifically, the chromaticity) and The light source unit 11 is controlled so that the amount of light is constant. As shown in FIG. 3, the light emitting state of the light source light in the second lighting scene may be the stimulation purity and the amount of light in the second light emitting state in the first lighting scene, and as shown in FIG. 4, the first The light emitting state may be larger than the stimulation purity and the amount of light of the second light emitting state in the lighting scene. Further, the light emitting state of the light source light in the second lighting scene may be a light emitting state smaller than the stimulation purity and the amount of light of the second light emitting state in the first lighting scene. Further, the chromaticity of the light source light may be the same or different between the first lighting scene and the second lighting scene.
　また、図５は、光源部１１が発する光源光の発光状態の、第２照明シーンにおける時間変化の例を示す図である。図５に示されるように、第２照明シーンでは、光源制御部１２は、光源光の発光状態を、第１発光状態と第２発光状態との間で、第１周期よりも長い第２周期で反復して変化させるように光源部１１を制御してもよい。第２周期は、例えば、第１周期の１．５倍以上であり、ユーザが光源光の発光状態の変化を気づきにくい周期に設定される。このように、第２照明シーンでは、光源光の発光状態の変化を少なくする又は無くすことで、ユーザを知的作業に集中させる照明環境を演出する。第２照明シーンにおける光源光の発光状態は、操作器２０のユーザの操作等に基づいて決定されてもよく、あらかじめユーザが知的作業に集中しやすい色度及び光量に設定されていてもよい。 Further, FIG. 5 is a diagram showing an example of a time change in the light emitting state of the light source light emitted by the light source unit 11 in the second lighting scene. As shown in FIG. 5, in the second lighting scene, the light source control unit 12 sets the light source light emission state between the first light emission state and the second light emission state in a second cycle longer than the first cycle. The light source unit 11 may be controlled so as to repeatedly change the light source unit 11. The second cycle is, for example, 1.5 times or more of the first cycle, and is set to a cycle in which the user does not easily notice the change in the light emission state of the light source light. In this way, in the second lighting scene, by reducing or eliminating the change in the light emission state of the light source light, a lighting environment that concentrates the user on intellectual work is produced. The light emitting state of the light source light in the second lighting scene may be determined based on the operation of the user of the actuator 20 or the like, or may be set in advance to a chromaticity and a light amount that make it easy for the user to concentrate on intellectual work. ..
　光源制御部１２は、例えば、所定の時間、第２照明シーンにした後、第１照明シーンに切り替えることを少なくとも１回以上繰り返すように光源部１１を制御する。これにより、ユーザが知的作業に集中できる第１照明シーンの後に、ユーザがリラックスできる第２照明シーンとなる照明環境が繰り返されるため、一定の間隔でユーザがリラックスすることができる。このように、知的作業中にユーザがリラックスして休憩することで、ユーザの集中力の低下を抑制できるため、知的作業中のユーザの集中力を持続させ、知的生産性を向上させることができる。 The light source control unit 12 controls the light source unit 11 so as to repeat switching to the first lighting scene at least once after setting the second lighting scene for a predetermined time, for example. As a result, the lighting environment that becomes the second lighting scene in which the user can relax is repeated after the first lighting scene in which the user can concentrate on the intellectual work, so that the user can relax at regular intervals. In this way, by allowing the user to relax and take a break during intellectual work, it is possible to suppress a decrease in the user's concentration, so that the user's concentration during intellectual work is maintained and intellectual productivity is improved. be able to.
　第１照明シーン及び第２照明シーンの継続時間、並びに、第１照明シーンと第２照明シーンとの切り替えタイミングは、後述する動作例で説明するように、操作器２０のユーザの操作等に基づいて決定されてもよいが、あらかじめ設定されていてもよい。第１照明シーンの継続時間があらかじめ設定されている場合、第１照明シーンの継続時間は、例えば、５分以上２０分以下である。これにより、ユーザを適度にリラックスさせ、ユーザが再び知的作業を行う際の集中力を効果的に高めることができる。また、第２照明シーンの継続時間があらかじめ設定されている場合、第２照明シーンの継続時間は、例えば、３０分以上１２０分以下である。この範囲の時間、第２照明シーンが継続してから第１照明シーンに切り替えられることで、ユーザの集中力が低下する前にユーザにリラックスを促すことができ、ユーザの集中力の低下を抑制できる。 The duration of the first lighting scene and the second lighting scene, and the switching timing between the first lighting scene and the second lighting scene are based on the operation of the user of the actuator 20 and the like as described in the operation example described later. It may be determined by, but it may be set in advance. When the duration of the first lighting scene is preset, the duration of the first lighting scene is, for example, 5 minutes or more and 20 minutes or less. This makes it possible to moderately relax the user and effectively increase the concentration of the user when performing intellectual work again. When the duration of the second lighting scene is set in advance, the duration of the second lighting scene is, for example, 30 minutes or more and 120 minutes or less. By switching to the first lighting scene after the second lighting scene continues for a period of time within this range, it is possible to encourage the user to relax before the user's concentration decreases, and the decrease in the user's concentration can be suppressed. can.
　また、光源制御部１２は、第１照明シーンにおいて、第１照明シーンの開始から終了にかけて、第１発光状態又は第２発光状態の光源光の光色が変化するように、光源部１１を制御してもよい。以下では、第１発光状態の光源光の光色が変化する場合の例について説明する。なお、第２発光状態の光源光の光色が、以下の説明と同様に変化してもよい。 Further, the light source control unit 12 controls the light source unit 11 so that the light color of the light source light in the first light emitting state or the second light emitting state changes from the start to the end of the first lighting scene in the first lighting scene. You may. Hereinafter, an example in which the light color of the light source light in the first light emitting state changes will be described. The light color of the light source light in the second light emitting state may change in the same manner as described below.
　図６は、第１照明シーンにおける第１発光状態の光色の変化を説明するためのＣＩＥ１９３１色空間のｘｙ色度図である。 FIG. 6 is an xy chromaticity diagram of the CIE 1931 color space for explaining the change in the light color of the first light emitting state in the first lighting scene.
　図６に示されるように、光源制御部１２は、第１照明シーンにおける第１発光状態の光源光の光色が、例えば、第１照明シーンの開始から終了にかけて、色度座標Ｃ１の第１光色から色度座標Ｃ３の第３光色を経由して色度座標Ｃ２の第２光色へ変化するように、光源部１１を制御する。第１光色と第２光色と第３光色とは、それぞれＪＩＳ　Ｚ８１１０－１９９５で定義される色名が異なる光色である。なお、光源制御部１２は、第１照明シーンにおける第１発光状態の光源光の光色が、第１照明シーンの開始から終了にかけて、第３光色を経由せずに第１光色から第２光色に変化するように、光源部１１を制御してもよい。また、この場合の第１光色及び第２光色の色度座標は、例えば、色度座標Ｃ１、Ｃ２及びＣ３のいずれの２つの組み合わせであってもよい。 As shown in FIG. 6, in the light source control unit 12, the light color of the light source light in the first light emitting state in the first lighting scene is, for example, the first of the chromaticity coordinates C1 from the start to the end of the first lighting scene. The light source unit 11 is controlled so as to change from the light color to the second light color of the chromaticity coordinate C2 via the third light color of the chromaticity coordinate C3. The first light color, the second light color, and the third light color are light colors having different color names defined in JIS Z8110-1995, respectively. In the light source control unit 12, the light color of the light source light in the first light emitting state in the first lighting scene changes from the first light color to the first light color from the start to the end of the first lighting scene without passing through the third light color. The light source unit 11 may be controlled so as to change to two light colors. Further, the chromaticity coordinates of the first light color and the second light color in this case may be, for example, a combination of any two of the chromaticity coordinates C1, C2, and C3.
　このように、第１照明シーンの開始時と終了時とで、光源光の光色が変化し、ユーザに与える光源光の印象が変化することで、ユーザに飽きを感じさせずに呼吸を誘導することができる。また、第１照明シーンの終了時の光色を、知的作業の性質及び重要度等に応じた心理生理的効果を与えることができる光色に設定することができる。また、光源光の光色が、第１光色から第２光色へ変化するまでに第３光色を経由することで、より光色の変化が増えるため、さらにユーザに飽きを感じさせずに呼吸を誘導することができる。 In this way, the light color of the light source light changes at the start and end of the first lighting scene, and the impression of the light source light given to the user changes, thereby inducing breathing without making the user feel bored. can do. Further, the light color at the end of the first lighting scene can be set to a light color that can give a psychophysiological effect according to the nature and importance of the intellectual work. In addition, the change in the light color increases by passing through the third light color until the light color of the light source light changes from the first light color to the second light color, so that the user does not feel bored. Can induce breathing.
　また、図６に示されるように、ＣＩＥ１９３１色空間における等エネルギー白色点ＣＷからｘ軸正方向側に延び、かつ、ｘ軸に平行な直線Ｌ０に対して、等エネルギー白色点ＣＷと第１光色の色度座標Ｃ１とを通る直線Ｌ１が成す角度をθ１とする。また、直線Ｌ０に対して、等エネルギー白色点ＣＷと第２光色の色度座標Ｃ２とを通る直線Ｌ２が成す角度をθ２とする。また、直線Ｌ０に対して、等エネルギー白色点ＣＷと第３光色の色度座標Ｃ３とを通る直線Ｌ３が成す角度をθ３とする。θ１、θ２及びθ３は、直線Ｌ０に対して、時計回り方向が正の値になる角度であり、－１８０度から＋１８０度の範囲である。この場合に、例えば、θ１とθ２とθ３とは、それぞれ異なる。これにより、第１照明シーンにおける光源光の光色の色相が変化し、ユーザに与える印象が変化しやすい光色の変化となるため、よりユーザが飽きることを抑制できる。 Further, as shown in FIG. 6, the iso-energy white point CW and the first light with respect to the straight line L0 extending in the positive direction of the x-axis from the iso-energy white point CW in the CIE1931 color space and parallel to the x-axis. Let θ1 be the angle formed by the straight line L1 passing through the color chromaticity coordinates C1. Further, the angle formed by the straight line L2 passing through the equal energy white point CW and the chromaticity coordinate C2 of the second light color with respect to the straight line L0 is defined as θ2. Further, the angle formed by the straight line L3 passing through the equal energy white point CW and the chromaticity coordinate C3 of the third light color with respect to the straight line L0 is defined as θ3. θ1, θ2, and θ3 are angles at which the clockwise direction becomes a positive value with respect to the straight line L0, and are in the range of −180 degrees to +180 degrees. In this case, for example, θ1, θ2, and θ3 are different from each other. As a result, the hue of the light color of the light source light in the first lighting scene changes, and the impression given to the user changes easily, so that it is possible to further suppress the user from getting bored.
　また、第１光色は、ＣＩＥ１９３１色空間において、色度座標（０．３０１６，０．６９２４）（図６で示される色度座標範囲外）と等エネルギー白色点ＣＷとを通る直線Ｌ１０よりｘ軸正方向側に位置する色度座標Ｃ１である。また、第２光色は、ＣＩＥ１９３１色空間において、直線Ｌ１０よりｘ軸負方向側に位置する色度座標Ｃ２である。直線Ｌ１０よりｘ軸正方向側に位置する色度座標は、暖色系の光色の色度座標であり、直線Ｌ１０よりｘ軸負方向側に位置する色度座標は、寒色系の光色の色度座標である。また、暖色系の光色は、人をリラックスさせる心理生理的効果が高く、寒色系の光色は、人を覚醒させる心理生理的効果が高い。そのため、光源制御部１２は、第１照明シーンを暖色系の第１光色で開始し、寒色系の第２光色で終了するように光源部１１を制御することで、暖色系の光色でユーザを効果的にリラックスさせつつ、寒色系の光色で覚醒させ、休憩から作業への切り替えを容易にできる。 Further, the first light color is x from the straight line L10 passing through the chromaticity coordinates (0.3016,0.6924) (outside the chromaticity coordinate range shown in FIG. 6) and the equal energy white point CW in the CIE1931 color space. The chromaticity coordinate C1 is located on the positive direction side of the axis. The second light color is the chromaticity coordinate C2 located on the negative direction side of the x-axis from the straight line L10 in the CIE1931 color space. The chromaticity coordinates located on the x-axis positive direction side of the straight line L10 are the chromaticity coordinates of the warm color system, and the chromaticity coordinates located on the x-axis negative direction side of the straight line L10 are the chromaticity coordinates of the cold color system. It is a chromaticity coordinate. In addition, warm-colored light colors have a high psychophysiological effect of relaxing a person, and cool-colored light colors have a high psycho-physiological effect of awakening a person. Therefore, the light source control unit 12 controls the light source unit 11 so that the first lighting scene starts with the first light color of the warm color system and ends with the second light color of the cold color system, so that the light color of the warm color system is used. While effectively relaxing the user, it is possible to awaken with cold light colors and easily switch from break to work.
　また、第１発光状態の光色を変化させる際、第２発光状態の光色は、等エネルギー白色点ＣＷ近傍の光色で一定であってもよい。また、第２発光状態の光色は、色度座標Ｃ１と等エネルギー白色点ＣＷとの間の光色から、色度座標Ｃ３と等エネルギー白色点ＣＷとの間の光色を経由して、色度座標Ｃ２と等エネルギー白色点ＣＷとの間の光色に変化してもよい。 Further, when changing the light color in the first light emitting state, the light color in the second light emitting state may be constant at the light color near the isoenergy white point CW. Further, the light color in the second light emitting state is transmitted from the light color between the chromaticity coordinates C1 and the equal energy white point CW to the light color between the chromaticity coordinates C3 and the equal energy white point CW. It may change to a light color between the chromaticity coordinate C2 and the equal energy white point CW.
　上述のように第１照明シーンにおいて光色を変化させる場合、例えば、光源部１１は、第１光源１１ａと第２光源１１ｂと第３光源１１ｃと第４光源１１ｄとで構成される。例えば、各光源として、第１光源１１ａには、等エネルギー白色点近傍の光色（例えば、ＪＩＳ　Ｚ８１１０－１９９５で定義される白色の基本色名領域円の内側の光色）の第１光を発する光源を用いる。また、第２光源１１ｂには、第１光色の第２光を発する光源を用いる。また、第３光源１１ｃには、第２光色の第３光を発する光源を用いる。また、第４光源１１ｄには、第３光色の第４光を発する光源を用いる。このような光源部１１の構成により、光源光における、第１発光状態と第２発光状態との変化、及び、第１照明シーンの開始から終了にかけての光色の変化が、細やかで自然な変化となる。また、第１照明シーンにおける第１発光状態の光源光の光色が、第１照明シーンの開始から終了にかけて、第３光色を経由せずに第１光色から第２光色に変化する場合には、光源部１１は、上述の構成のうち第１光源１１ａ、第２光源１１ｂ及び第３光源１１ｃとで構成される。 When changing the light color in the first lighting scene as described above, for example, the light source unit 11 is composed of a first light source 11a, a second light source 11b, a third light source 11c, and a fourth light source 11d. For example, as each light source, the first light source 11a is provided with the first light having a light color near the equal energy white point (for example, the light color inside the white basic color name region circle defined in JIS Z8110-1995). Use a light source that emits light. Further, as the second light source 11b, a light source that emits the second light of the first light color is used. Further, as the third light source 11c, a light source that emits the third light of the second light color is used. Further, as the fourth light source 11d, a light source that emits the fourth light of the third light color is used. With such a configuration of the light source unit 11, the change between the first light emitting state and the second light emitting state and the change in the light color from the start to the end of the first lighting scene in the light source light are delicate and natural changes. It becomes. Further, the light color of the light source light in the first light emitting state in the first lighting scene changes from the first light color to the second light color from the start to the end of the first lighting scene without passing through the third light color. In this case, the light source unit 11 is composed of the first light source 11a, the second light source 11b, and the third light source 11c in the above configuration.
　光源制御部１２は、例えば、第１照明シーンの開始時には、第１光源１１ａと第２光源１１ｂとの光量を調整することで、第１発光状態と第２発光状態との間で反復して変化させる。具体的には、光源制御部１２は、光源光を第１発光状態にする場合、第２光源１１ｂの光量が第１光源１１ａの光源よりも多くなるように、若しくは、第２光源１１ｂのみを発光させるように制御する。時間が経過するにつれて、光源制御部１２は、光源光を第１発光状態にする場合に、第４光源１１ｄも発光させ、第２光源１１ｂと第４光源１１ｄとの光量を調整することで、第１発光状態の光色を第１光色から第３光色に変化させる。さらに、光源制御部１２は、第１発光状態の光色が第３光色になった場合には、第２光源１１ｂを発光させず、第３光源１１ｃを発光させ、第４光源１１ｄと第３光源１１ｃとの光量を調整することで、第１発光状態の光色を第３光色から第２光色に変化させる。また、光源制御部１２は、光源光を第２発光状態にする場合、第１光源１１ａの光量が第２光源１１ｂ、第３光源１１ｃ、第４光源１１ｄのいずれの光源よりも多くなるように、若しくは、第１光源１１ａのみを発光させるように制御する。このように光源制御部１２が光源部１１を制御することで、上述のような第１照明シーンにおける光色及び発光状態の変化が実現できる。 For example, at the start of the first lighting scene, the light source control unit 12 repeats between the first light emitting state and the second light emitting state by adjusting the amount of light between the first light source 11a and the second light source 11b. Change. Specifically, when the light source light is brought into the first light emitting state, the light source control unit 12 makes the amount of light of the second light source 11b larger than that of the light source of the first light source 11a, or sets only the second light source 11b. Control to emit light. As time elapses, the light source control unit 12 also causes the fourth light source 11d to emit light when the light source light is brought into the first light emitting state, and adjusts the amount of light between the second light source 11b and the fourth light source 11d. The light color in the first light emitting state is changed from the first light color to the third light color. Further, when the light color in the first light emitting state becomes the third light color, the light source control unit 12 does not emit the second light source 11b, but causes the third light source 11c to emit light, and the fourth light source 11d and the third light source 12d. By adjusting the amount of light with the three light sources 11c, the light color in the first light emitting state is changed from the third light color to the second light color. Further, when the light source light is brought into the second light emitting state, the light source control unit 12 makes the amount of light of the first light source 11a larger than that of any of the second light source 11b, the third light source 11c, and the fourth light source 11d. Or, control is performed so that only the first light source 11a emits light. By controlling the light source unit 11 by the light source control unit 12 in this way, it is possible to realize changes in the light color and the light emitting state in the first lighting scene as described above.
　図７Ａは、第１照明シーンにおいて、第１発光状態と第２発光状態との間で反復して変化させる１回の周期における光色の変化を説明するためのＣＩＥ１９７６　ＵＣＳ色度図である。また、図７Ｂは、第１照明シーンにおいて、第１発光状態と第２発光状態との間で反復して変化させる１回の周期における光色の変化を説明するための周期と色相角の関係を示す図である。 FIG. 7A is a CIE1976 UCS chromaticity diagram for explaining a change in light color in one cycle of repeatedly changing between a first light emitting state and a second light emitting state in a first lighting scene. Further, FIG. 7B shows the relationship between the cycle and the hue angle for explaining the change in light color in one cycle of repeatedly changing between the first light emitting state and the second light emitting state in the first lighting scene. It is a figure which shows.
　図７Ａ及び図７Ｂに示されるように、第１照明シーンにおいて、ＣＩＥ１９７６　ＵＣＳ色度図における、第１発光状態と第２発光状態との間で反復して変化させる１回の周期の開始時における光色の色度座標ａとし、当該１回の周期の終了時における光色を色度座標ｂとする。光源制御部１２は、例えば、第１照明シーンにおいて、色度座標ａと色度座標ｂとがなす色相角の大きさθ４が２５°以下になるように光源部１１を制御する。 As shown in FIGS. 7A and 7B, in the first lighting scene, at the start of one cycle of repeatedly changing between the first light emitting state and the second light emitting state in the CIE1976 UCS chromaticity diagram. Let the chromaticity coordinate a of the light color be, and let the chromaticity coordinate b be the light color at the end of the one cycle. For example, in the first lighting scene, the light source control unit 12 controls the light source unit 11 so that the magnitude θ4 of the hue angle formed by the chromaticity coordinates a and the chromaticity coordinates b is 25 ° or less.
　２つの光色の色相角が２５°以下である場合、人は同一色又は同系色に見えるとされている変化であるため、第１照明シーンにおいて、第１発光状態又は第２発光状態の光色が変化する場合であっても、ユーザに違和感を感じさせにくい。よって、このようにθ４が２５°以下になるように光源部１１が制御されることで、ユーザに飽きを感じさせず、且つ、ユーザに違和感を感じさせずに呼吸を誘導することができる。 When the hue angle of the two light colors is 25 ° or less, it is a change that a person looks like the same color or a similar color. Therefore, in the first lighting scene, the light in the first light emitting state or the second light emitting state. Even when the color changes, it is difficult for the user to feel a sense of discomfort. Therefore, by controlling the light source unit 11 so that θ4 is 25 ° or less in this way, it is possible to induce respiration without making the user feel bored and the user does not feel discomfort.
　なお、第１照明シーンにおける光源光の光色は、上記説明のような変化に限らない。第１光色、第２光色及び第３光色は、それぞれ、ＪＩＳ　Ｚ８１１０－１９９５で定義される色名が異なる光色であれば、どのような色度を有していてもよい。第１光色、第２光色及び第３光色は、上記説明のような光色にあらかじめ設定されていてもよく、操作器２０のユーザの操作等に基づいて決定されてもよい。光色が操作器２０のユーザの操作等に基づいて決定される場合、例えば、光源部１１は、赤色、緑色及び青色の組み合わせとなる第１光、第２光及び第３光を発する第１光源１１ａ、第２光源１１ｂ及び第３光源１１ｃで構成される。 The light color of the light source light in the first lighting scene is not limited to the change as described above. The first light color, the second light color, and the third light color may have any chromaticity as long as they have different light colors defined in JIS Z8110-1995. The first light color, the second light color, and the third light color may be preset to the light colors as described above, or may be determined based on the operation of the user of the actuator 20 or the like. When the light color is determined based on the operation of the user of the operator 20, for example, the light source unit 11 emits the first light, the second light, and the third light which are a combination of red, green, and blue. It is composed of a light source 11a, a second light source 11b, and a third light source 11c.
　［動作例］
　次に、照明システム１における動作例について説明する。 [Operation example]
Next, an operation example in the lighting system 1 will be described.
　まず、照明システム１の動作例１について説明する。動作例１は、ユーザの操作によって第１周期が設定される場合の動作例である。図８は、照明システム１の動作例１のフローチャートである。 First, operation example 1 of the lighting system 1 will be described. The operation example 1 is an operation example when the first cycle is set by the operation of the user. FIG. 8 is a flowchart of an operation example 1 of the lighting system 1.
　まず、操作器２０の第１入力部２１は、第１周期を示す第１操作情報を入力する操作をユーザから受け付ける（ステップＳ１１）。操作器２０の制御部２４は、ユーザから入力を受け付けた第１操作情報を、照明器具１０へ通信部２５に送信させる。次に、光源制御部１２は、ユーザの操作により入力された第１操作情報を、通信部１８を介して取得する（ステップＳ１２）。そして、光源制御部１２は、第１照明シーンにおいて、光源光の発光状態を、第１発光状態と第２発光状態との間で、取得した第１操作情報が示す第１周期で反復して変化させるように光源部１１を制御する（ステップＳ１３）。これにより、光源部１１は、ユーザが入力した第１周期で第１照明シーンの発光状態が制御された光源光を照射する。 First, the first input unit 21 of the actuator 20 receives an operation for inputting the first operation information indicating the first cycle from the user (step S11). The control unit 24 of the operation device 20 causes the lighting equipment 10 to transmit the first operation information received from the user to the communication unit 25. Next, the light source control unit 12 acquires the first operation information input by the user's operation via the communication unit 18 (step S12). Then, in the first lighting scene, the light source control unit 12 repeats the light source light emission state between the first light emission state and the second light emission state in the first cycle indicated by the acquired first operation information. The light source unit 11 is controlled so as to be changed (step S13). As a result, the light source unit 11 irradiates the light source light whose light emission state of the first lighting scene is controlled in the first cycle input by the user.
　これにより、ユーザが任意で第１周期を設定できるため、光源部１１は、ユーザの知的作業時の体調及び気分等に応じた第１周期で呼吸を誘導するための光源光を発することができる。よって、第１照明シーンにおいて、より効果的にユーザをリラックスさせることで、ユーザの知的生産性を向上させることができる。 As a result, the user can arbitrarily set the first cycle, so that the light source unit 11 emits light source light for inducing respiration in the first cycle according to the physical condition and mood of the user during intellectual work. can. Therefore, in the first lighting scene, the intellectual productivity of the user can be improved by relaxing the user more effectively.
　次に、照明システム１の動作例２について説明する。動作例２は、ユーザの操作によって、第１照明シーンと第２照明シーンとの切り替えが行われる動作例である。図９は、照明システム１の動作例２のフローチャートである。 Next, operation example 2 of the lighting system 1 will be described. The operation example 2 is an operation example in which the first lighting scene and the second lighting scene are switched by the user's operation. FIG. 9 is a flowchart of an operation example 2 of the lighting system 1.
　まず、操作器２０の第２入力部は、第１照明シーンと第２照明シーンとの切り替えタイミング、並びに、第１照明シーン及び第２照明シーンの継続時間の少なくとも一方を示す第２操作情報を入力する操作をユーザから受け付ける（ステップＳ２１）。操作器２０の制御部２４は、ユーザから入力を受け付けた第２操作情報を、照明器具１０へ通信部２５に送信させる。次に、光源制御部１２は、ユーザの操作により入力された第２操作情報を、通信部１８を介して取得する（ステップＳ２２）。そして、光源制御部１２は、取得した第２操作情報に基づいて第１照明シーンと第２照明シーンとを切り替えるように光源部１１を制御する（ステップＳ２３）。 First, the second input unit of the controller 20 provides second operation information indicating at least one of the switching timing between the first lighting scene and the second lighting scene and the duration of the first lighting scene and the second lighting scene. The operation to be input is accepted from the user (step S21). The control unit 24 of the operation device 20 causes the lighting fixture 10 to transmit the second operation information received from the user to the communication unit 25. Next, the light source control unit 12 acquires the second operation information input by the user's operation via the communication unit 18 (step S22). Then, the light source control unit 12 controls the light source unit 11 so as to switch between the first lighting scene and the second lighting scene based on the acquired second operation information (step S23).
　例えば、第２操作情報が第１照明シーンと第２照明シーンとの切り替えタイミングを示す情報の場合、光源制御部１２は、第１照明シーン又は第２照明シーンで光源部１１を制御している際に、第２操作情報を取得する。そして、光源制御部１２は、第２操作情報が示すタイミングで、第１照明シーンと第２照明シーンとを切り替えるように光源部１１を制御する。例えば、この場合の第２操作情報は、第１照明シーンと第２照明シーンとの切り替えを即時に実施させるトリガを示す情報であり、光源制御部１２が第２操作情報を取得してすぐに第１照明シーンと第２照明シーンとが切り替わる。また、第２操作情報は、第１照明シーンと第２照明シーンとの切り替え時刻、又は、第１照明シーン及び第２照明シーンの開始及び終了の時刻を示す情報であってもよい。 For example, when the second operation information is information indicating the switching timing between the first lighting scene and the second lighting scene, the light source control unit 12 controls the light source unit 11 in the first lighting scene or the second lighting scene. At that time, the second operation information is acquired. Then, the light source control unit 12 controls the light source unit 11 so as to switch between the first lighting scene and the second lighting scene at the timing indicated by the second operation information. For example, the second operation information in this case is information indicating a trigger for immediately switching between the first lighting scene and the second lighting scene, and the light source control unit 12 immediately acquires the second operation information. The first lighting scene and the second lighting scene are switched. Further, the second operation information may be information indicating the switching time between the first lighting scene and the second lighting scene, or the start and end times of the first lighting scene and the second lighting scene.
　また、例えば、第２操作情報が第１照明シーン及び第２照明シーンの継続時間を示す情報の場合、光源制御部１２は、光源部１１の制御を開始する前に、第２操作情報を取得する。そして、光源制御部１２は、光源部１１の制御を開始し、第２操作情報が示す継続時間が経過した時点で、第１照明シーンと第２照明シーンとを切り替えるように光源部１１を制御する。 Further, for example, when the second operation information is information indicating the duration of the first lighting scene and the second lighting scene, the light source control unit 12 acquires the second operation information before starting the control of the light source unit 11. do. Then, the light source control unit 12 starts controlling the light source unit 11, and controls the light source unit 11 so as to switch between the first lighting scene and the second lighting scene when the duration indicated by the second operation information has elapsed. do.
　これにより、ユーザが任意のタイミングで第１照明シーンと第２照明シーンとを切り替えられるため、光源制御部１２は、ユーザの知的作業時の体調及び気分等に応じたタイミングで第１照明シーンと第２照明シーンとを切り替えることができる。よって、より効果的なタイミングでユーザをリラックスさせるシーンと知的作業に集中させるシーンとを切り替えることができるため、ユーザの知的生産性を向上させることができる。 As a result, the user can switch between the first lighting scene and the second lighting scene at an arbitrary timing, so that the light source control unit 12 can switch the first lighting scene at a timing according to the physical condition and mood of the user during intellectual work. And the second lighting scene can be switched. Therefore, it is possible to switch between a scene in which the user is relaxed and a scene in which the user is focused on intellectual work at a more effective timing, so that the intellectual productivity of the user can be improved.
　次に、照明システム１の動作例３について説明する。動作例３は、照明器具１０が音響装置３０と連動して、光源部１１の光源光の発光状態を制御する場合の動作例である。図１０は、照明システム１の動作例３のシーケンス図である。 Next, operation example 3 of the lighting system 1 will be described. The operation example 3 is an operation example in which the luminaire 10 controls the light emission state of the light source light of the light source unit 11 in conjunction with the audio device 30. FIG. 10 is a sequence diagram of an operation example 3 of the lighting system 1.
　まず、最初、ユーザによって照明器具１０の点灯操作が行われ、照明器具１０の光源制御部１２は、光源部１１の制御を開始する。その際、照明器具１０の光源制御部１２は、第２照明シーンで光源部１１の光源光の発光状態を制御する（ステップＳ３１）。次に、音響装置３０の操作部３２は、ユーザから楽曲再生部３１に再生させる楽曲の選択を受け付ける（ステップＳ３２）。そして、制御部３３は、ユーザが選択した楽曲に関する楽曲情報を通信部３５に送信させる（ステップＳ３３）。照明器具１０の楽曲解析部１４は、通信部１８を介して、音響装置３０からの楽曲情報を取得する。つまり、楽曲解析部１４は、照明システム１が設置されている空間に流れる楽曲に関する楽曲情報を取得する。 First, the user performs a lighting operation of the lighting fixture 10, and the light source control unit 12 of the lighting fixture 10 starts controlling the light source unit 11. At that time, the light source control unit 12 of the lighting fixture 10 controls the light emission state of the light source light of the light source unit 11 in the second lighting scene (step S31). Next, the operation unit 32 of the audio device 30 accepts the selection of the music to be reproduced by the music reproduction unit 31 from the user (step S32). Then, the control unit 33 causes the communication unit 35 to transmit music information related to the music selected by the user (step S33). The music analysis unit 14 of the lighting fixture 10 acquires music information from the audio device 30 via the communication unit 18. That is, the music analysis unit 14 acquires music information related to the music flowing in the space where the lighting system 1 is installed.
　そして、楽曲解析部１４は、取得した楽曲情報における楽曲の特徴に基づいて、第１周期を示す周期情報を生成する（ステップＳ３４）。具体的には、楽曲解析部１４は、例えば、公知のテンポ解析手法等を用いて、取得した楽曲情報における楽曲の特徴として楽曲のＢＰＭ（Ｂｅａｔｓ　Ｐｅｒ　Ｍｉｎｕｔｅ）を取得する。そして、楽曲解析部１４は、楽曲のＢＰＭに基づいて、第１周期を決定する。楽曲解析部１４は、例えば、第１周期が、周波数が４．５ｃｙｃｌｅ／ｍｉｎ以上７ｃｙｃｌｅ／ｍｉｎ以下の周期、且つ、ＢＰＭの逆数である楽曲の拍間隔の整数倍の周期になるように、第１周期を決定し、決定した第１周期を示す周期情報を生成する。楽曲解析部１４は、生成した周期情報を光源制御部１２に送信する。 Then, the music analysis unit 14 generates cycle information indicating the first cycle based on the characteristics of the music in the acquired music information (step S34). Specifically, the music analysis unit 14 acquires the BPM (Beats Per Minute) of the music as a feature of the music in the acquired music information by using, for example, a known tempo analysis method or the like. Then, the music analysis unit 14 determines the first cycle based on the BPM of the music. For example, the music analysis unit 14 has a first period such that the frequency is 4.5 cycles / min or more and 7 cycles / min or less, and is an integral multiple of the beat interval of the music, which is the reciprocal of BPM. One cycle is determined, and cycle information indicating the determined first cycle is generated. The music analysis unit 14 transmits the generated periodic information to the light source control unit 12.
　次に、光源制御部１２は、第１照明シーンの開始のタイミングで、楽曲再生部３１に楽曲を再生させるための再生タイミングを示す再生情報を、通信部３５を介して音響装置３０に送信する（ステップＳ３５）。制御部３３は、通信部３５を介して、送信された再生情報を取得する。ステップＳ３５での再生情報の送信した後、光源制御部１２は、第２照明シーンでの光源部１１の制御を終了し、第１照明シーンでの光源部１１の制御を開始する（ステップＳ３６）。また、光源制御部１２は、第１照明シーンにおいて、光源光の発光状態を、第１発光状態と第２発光状態との間で、周期情報が示す第１周期で反復して変化させるように光源部１１を制御する（ステップＳ３７）。また、音響装置３０の楽曲再生部３１は、光源制御部１２による第１照明シーンの開始のタイミングと同期して、ステップＳ３２によってユーザにより選択された楽曲を再生する（ステップＳ３８）。具体的には、制御部３３は、取得した再生情報に基づいて、光源制御部１２による第１照明シーンの開始のタイミングと同期して、楽曲再生部３１に楽曲を再生させる。これにより、光源制御部１２が第１照明シーンで光源部１１を制御している間、照明システム１が設置されている空間で楽曲が再生される。 Next, at the start timing of the first lighting scene, the light source control unit 12 transmits the reproduction information indicating the reproduction timing for causing the music reproduction unit 31 to reproduce the music to the sound device 30 via the communication unit 35. (Step S35). The control unit 33 acquires the transmitted reproduction information via the communication unit 35. After transmitting the reproduction information in step S35, the light source control unit 12 ends the control of the light source unit 11 in the second lighting scene and starts the control of the light source unit 11 in the first lighting scene (step S36). .. Further, the light source control unit 12 repeatedly changes the light source light emission state between the first light emission state and the second light emission state in the first cycle indicated by the cycle information in the first lighting scene. The light source unit 11 is controlled (step S37). Further, the music reproduction unit 31 of the audio device 30 reproduces the music selected by the user in step S32 in synchronization with the start timing of the first lighting scene by the light source control unit 12 (step S38). Specifically, the control unit 33 causes the music reproduction unit 31 to reproduce the music based on the acquired reproduction information in synchronization with the start timing of the first lighting scene by the light source control unit 12. As a result, while the light source control unit 12 controls the light source unit 11 in the first lighting scene, the music is reproduced in the space where the lighting system 1 is installed.
　これにより、第１照明シーンでユーザに呼吸を誘導する際に、楽曲の特徴と第１照明シーンにおける光源光の変動の周期とがあった環境にできるため、ユーザに呼吸をより誘導しやすくなる。その結果、より効果的にユーザをリラックスさせることができる。 As a result, when inducing the user to breathe in the first lighting scene, it is possible to create an environment in which the characteristics of the music and the period of fluctuation of the light source light in the first lighting scene are present, so that it becomes easier to induce the user to breathe. .. As a result, the user can be relaxed more effectively.
　なお、ステップＳ３２でのユーザからの楽曲の選択が行われず、楽曲再生部３１は、あらかじめ定められた楽曲を再生してもよい。この場合、ステップＳ３３では、制御部３３は、あらかじめ定められた楽曲に関する楽曲情報を通信部３５に送信させる。 Note that the music is not selected by the user in step S32, and the music reproduction unit 31 may reproduce a predetermined music. In this case, in step S33, the control unit 33 causes the communication unit 35 to transmit music information related to the predetermined music.
　また、ステップＳ３５において、光源制御部１２が音響装置３０に再生情報を送信したが、制御部３３が楽曲再生部３１に楽曲を再生させるタイミングを示す情報を光源制御部１２に送信してもよい。この場合、光源制御部１２が、楽曲再生部３１による楽曲の再生のタイミングに合わせて、第１照明シーンでの光源部１１の制御を開始することで、楽曲再生部３１が、光源制御部１２による第１照明シーンの開始のタイミングと同期して、楽曲を再生する。 Further, in step S35, the light source control unit 12 transmits the reproduction information to the audio device 30, but the control unit 33 may transmit the information indicating the timing for causing the music reproduction unit 31 to reproduce the music to the light source control unit 12. .. In this case, the light source control unit 12 starts controlling the light source unit 11 in the first lighting scene in accordance with the timing of playing the music by the music reproduction unit 31, so that the music reproduction unit 31 can perform the light source control unit 12. The music is played in synchronization with the start timing of the first lighting scene by.
　また、動作例３において、楽曲再生部３１は、光源制御部１２による第１照明シーンの開始のタイミングと同期して、楽曲を再生したが、これに限らない。楽曲再生部３１は、常時、照明システム１が設置されている空間に楽曲を流していてもよい。この場合、楽曲解析部１４は、光源制御部１２による第１照明シーンの制御の開始前に、照明システム１が設置されている空間に流れている楽曲に関する楽曲情報を取得し、取得した楽曲情報に基づいて周期情報を生成する。つまり、動作例３におけるステップＳ３２、Ｓ３５及びＳ３８が省略されてもよい。 Further, in the operation example 3, the music reproduction unit 31 reproduces the music in synchronization with the start timing of the first lighting scene by the light source control unit 12, but the present invention is not limited to this. The music reproduction unit 31 may constantly play music in the space where the lighting system 1 is installed. In this case, the music analysis unit 14 acquires music information related to the music flowing in the space where the lighting system 1 is installed before the start of control of the first lighting scene by the light source control unit 12, and the acquired music information. Periodic information is generated based on. That is, steps S32, S35 and S38 in the operation example 3 may be omitted.
　また、楽曲解析部１４は、マイク等の集音装置を介して、照明システム１が設置されている空間に流れている楽曲に関する楽曲情報を取得してもよい。 Further, the music analysis unit 14 may acquire music information about the music flowing in the space where the lighting system 1 is installed via a sound collecting device such as a microphone.
　次に、照明システム１の動作例４について説明する。動作例４は、センサ４０から取得した情報に基づいて、光源制御部１２が光源部１１を制御する場合の動作例である。図１１は、照明システム１の動作例４のフローチャートである。動作例４では、センサ４０がイメージセンサである場合について説明するが、センサ４０は他の種類のセンサであってもよい。 Next, operation example 4 of the lighting system 1 will be described. The operation example 4 is an operation example in which the light source control unit 12 controls the light source unit 11 based on the information acquired from the sensor 40. FIG. 11 is a flowchart of an operation example 4 of the lighting system 1. In the operation example 4, the case where the sensor 40 is an image sensor will be described, but the sensor 40 may be another type of sensor.
　まず、照明器具１０のセンシング部１５は、センサ４０から取得した情報に基づいて、照明器具１０の光源光の照射範囲の周囲の人（例えば、知的作業を行うユーザ）の存在を特定する（ステップＳ４１）。例えば、センシング部１５は、センサ４０が取得した画像から、照明器具１０の周囲に人が存在するかどうかを特定する。また、例えば、センサ４０が人感センサ又は着座センサ等のセンサである場合は、センサの人の検知結果又は着座の検知結果から、センシング部１５は、照明器具１０の周囲に人が存在するかどうかを特定する。 First, the sensing unit 15 of the lighting fixture 10 identifies the existence of a person (for example, a user who performs intellectual work) around the irradiation range of the light source light of the lighting fixture 10 based on the information acquired from the sensor 40 (for example, the user who performs intellectual work). Step S41). For example, the sensing unit 15 identifies whether or not a person exists around the lighting fixture 10 from the image acquired by the sensor 40. Further, for example, when the sensor 40 is a sensor such as a motion sensor or a seating sensor, whether there is a person around the lighting fixture 10 in the sensing unit 15 based on the human detection result of the sensor or the seating detection result. Identify if.
　そして、光源制御部１２は、センシング部１５が人の存在を特定したタイミングで、第２照明シーンでの光源部１１の制御を開始する（ステップＳ４２）。具体的には、センシング部１５は、人の存在を特定した場合に、光源部１１の制御を開始させる制御信号を光源制御部１２に送信し、光源制御部１２は、制御信号を受け取ったタイミングで、第２照明シーンでの光源部１１の制御を開始する。 Then, the light source control unit 12 starts controlling the light source unit 11 in the second lighting scene at the timing when the sensing unit 15 identifies the existence of a person (step S42). Specifically, when the sensing unit 15 identifies the existence of a person, the sensing unit 15 transmits a control signal for starting the control of the light source unit 11 to the light source control unit 12, and the light source control unit 12 receives the control signal at the timing. Then, the control of the light source unit 11 in the second lighting scene is started.
　次に、センシング部１５は、センサ４０から取得した情報に含まれる生体情報に基づいて、人の状態を特定する（ステップＳ４３）。例えば、センシング部１５は、一定時間ごとに、センサから取得した画像から、生体情報として、人の瞳孔の様子、視線、表情及びポーズ等に関する情報を取得する。センシング部１５は、例えば、公知のアイトラッキング手法又は画像解析手法を用いて生体情報を取得する。また、例えば、生体情報と人の疲労度との関係性を示す情報が記憶部１６に記憶されており、センシング部１５は、記憶部１６の情報を参照することで、取得した生体情報に基づいて、人の状況として人の疲労度を決定する。また、センシング部１５は、生体情報として、視線に関する情報を取得する場合、例えば、視線の移動度が小さいほど疲労度が低く、視線の移動度が大きいほど疲労度が高いとして、人の疲労度を決定する。そして、センシング部１５は、一定時間ごとに、決定した人の疲労度を、記憶部１６に記憶させる。 Next, the sensing unit 15 identifies the state of a person based on the biometric information included in the information acquired from the sensor 40 (step S43). For example, the sensing unit 15 acquires information on the state of the human pupil, the line of sight, the facial expression, the pose, and the like as biological information from the image acquired from the sensor at regular intervals. The sensing unit 15 acquires biometric information using, for example, a known eye tracking method or image analysis method. Further, for example, information indicating the relationship between the biological information and the degree of human fatigue is stored in the storage unit 16, and the sensing unit 15 refers to the information in the storage unit 16 based on the acquired biological information. Therefore, the degree of fatigue of a person is determined as the situation of the person. Further, when the sensing unit 15 acquires information about the line of sight as biological information, for example, it is assumed that the smaller the mobility of the line of sight is, the lower the fatigue level is, and the greater the mobility of the line of sight is, the higher the fatigue level is. To determine. Then, the sensing unit 15 stores the determined person's fatigue level in the storage unit 16 at regular time intervals.
　次に、光源制御部１２は、センシング部１５が特定した人の状況の変化に基づいたタイミングで、光源部１１の制御を、第２照明シーンから第１照明シーンに切り替えるように光源部１１を制御する（ステップＳ４４）。例えば、光源制御部１２は、特定した人の状況として記憶部１６に記憶された人の疲労度を参照する。そして、光源制御部１２は、第２照明シーンの開始時の人の疲労度と比較して、疲労度が所定の値以上上昇した場合に、第２照明シーンから第１照明シーンに切り替えるように光源部１１を制御する。 Next, the light source control unit 12 switches the light source unit 11 so as to switch the control of the light source unit 11 from the second lighting scene to the first lighting scene at a timing based on the change in the situation of the person specified by the sensing unit 15. Control (step S44). For example, the light source control unit 12 refers to the degree of fatigue of a person stored in the storage unit 16 as the situation of the specified person. Then, the light source control unit 12 switches from the second lighting scene to the first lighting scene when the fatigue level rises by a predetermined value or more as compared with the fatigue level of the person at the start of the second lighting scene. The light source unit 11 is controlled.
　このように、センシング部１５が、人の状況を特定して、光源制御部１２が、例えば人の疲労度等の人の状況の変化に応じたタイミングで第２照明シーンから第１照明シーンに切り替えるように光源部１１を制御する。そのため、例えば、知的作業を行うユーザが疲れたタイミングで、ユーザにリラックスを促す第１照明シーンに切り替えることができるため、効果的にユーザをリラックスさせることができる。 In this way, the sensing unit 15 identifies the human situation, and the light source control unit 12 changes from the second lighting scene to the first lighting scene at a timing corresponding to a change in the human situation such as the degree of fatigue of the person. The light source unit 11 is controlled so as to switch. Therefore, for example, when the user performing the intellectual work is tired, the user can be switched to the first lighting scene that encourages the user to relax, so that the user can be effectively relaxed.
　なお、動作例４において、光源制御部１２は、ステップＳ４２の後、所定の時間後に第２照明シーンから第１照明シーンに切り替えてもよい。所定の時間として、あらかじめ人の集中力の継続時間に応じた時間が設定されていてもよく、動作例２のように、光源制御部１２が、第２操作情報に基づいて、第２照明シーンから第１照明シーンに切り替えてもよい。 In operation example 4, the light source control unit 12 may switch from the second lighting scene to the first lighting scene after a predetermined time after step S42. As a predetermined time, a time corresponding to the duration of the concentration of a person may be set in advance, and as in the operation example 2, the light source control unit 12 determines the second lighting scene based on the second operation information. May switch to the first lighting scene.
　また、ステップＳ４１におけるセンサ４０と、ステップＳ４３におけるセンサ４０とは、同一のセンサであってもよく、異なるセンサであってもよい。 Further, the sensor 40 in step S41 and the sensor 40 in step S43 may be the same sensor or different sensors.
　次に、照明システム１の動作例５について説明する。動作例５は、ユーザのスケジュールに応じた光色で、光源制御部１２が光源部１１を制御する場合の動作例である。図１２は、照明システム１の動作例５のフローチャートである。 Next, operation example 5 of the lighting system 1 will be described. The operation example 5 is an operation example in which the light source control unit 12 controls the light source unit 11 with a light color according to the user's schedule. FIG. 12 is a flowchart of an operation example 5 of the lighting system 1.
　まず、光源制御部１２は、ユーザの予定を示すスケジュール情報を取得する（ステップＳ５１）。スケジュール情報は、例えば、操作器２０の第３入力部２３を操作することでユーザから入力されたスケジュール情報である。光源制御部１２は、操作器２０からスケジュール情報を取得する。また、光源制御部１２は、通信部１８を介して、クラウドサーバ等に記憶されているスケジュール情報を取得してもよい。次に、光源制御部１２は、スケジュール情報に基づいて、ユーザの予定の重要度を特定する（ステップＳ５２）。例えば、ユーザの予定と予定の重要度との関係性を示す情報が記憶部１６に記憶されており、光源制御部１２は、記憶部１６の情報を参照することで、ユーザの予定の重要度を特定する。また、スケジュール情報に、ユーザの予定の重要度を示す情報が含まれていてもよい。 First, the light source control unit 12 acquires schedule information indicating the user's schedule (step S51). The schedule information is, for example, the schedule information input by the user by operating the third input unit 23 of the actuator 20. The light source control unit 12 acquires schedule information from the actuator 20. Further, the light source control unit 12 may acquire the schedule information stored in the cloud server or the like via the communication unit 18. Next, the light source control unit 12 identifies the importance of the user's schedule based on the schedule information (step S52). For example, information indicating the relationship between the user's schedule and the importance of the schedule is stored in the storage unit 16, and the light source control unit 12 refers to the information in the storage unit 16 to obtain the importance of the user's schedule. To identify. In addition, the schedule information may include information indicating the importance of the user's schedule.
　次に、光源制御部１２は、第１照明シーンでの光源部１１の制御を開始する際、当該第１照明シーンでの制御後の予定の重要度に基づいて、第１照明シーンにおける光色を決定する（ステップＳ５３）。そして、光源制御部１２は、決定した光色で、第１照明シーンでの光源部１１の制御を開始する（ステップＳ５４）。例えば、光源制御部１２は、当該第１照明シーンでの制御後の予定の重要度が一定以上高い場合、第１発光状態における光色を、第１照明シーンの開始時に暖色系の光色とし、第１照明シーンの終了時に寒色系の光色になるように変化させて光源部１１を制御する。これにより、第１照明シーンが覚醒度を高めやすい寒色系の光色で終了し、ユーザが重要な予定へ移行しやすくなる。また、例えば、光源制御部１２は、当該第１照明シーンでの制御後の予定の重要度が一定以上高くない場合、第１発光状態における光色を、暖色系の光色のままで変化させずに光源部１１を制御する。これにより、第１照明シーンにおいて、ユーザをリラックスさせる効果を高め、知的作業中のユーザの集中力をより持続させる。 Next, when the light source control unit 12 starts controlling the light source unit 11 in the first lighting scene, the light color in the first lighting scene is based on the importance of the schedule after the control in the first lighting scene. Is determined (step S53). Then, the light source control unit 12 starts controlling the light source unit 11 in the first lighting scene with the determined light color (step S54). For example, when the importance of the planned after control in the first lighting scene is higher than a certain level, the light source control unit 12 sets the light color in the first light emitting state as a warm color at the start of the first lighting scene. At the end of the first lighting scene, the light source unit 11 is controlled by changing the light color so that it becomes a cold light color. As a result, the first lighting scene ends with a cool light color that tends to increase the arousal level, and it becomes easy for the user to shift to an important schedule. Further, for example, when the importance of the planned after control in the first lighting scene is not higher than a certain level, the light source control unit 12 changes the light color in the first light emitting state with the light color of the warm color system as it is. The light source unit 11 is controlled without the need for control. As a result, in the first lighting scene, the effect of relaxing the user is enhanced, and the concentration of the user during intellectual work is further maintained.
　［効果等］
　以上説明したように、本実施の形態に係る照明システム１は、第１光を発する第１光源１１ａ及び第１光と異なる色度を有する第２光を発する第２光源１１ｂを含む光源部１１と、光源部１１が発する光源光の発光状態を制御する光源制御部１２とを備える。光源制御部１２は、第１照明シーンと第２照明シーンとを切り替えるように光源部１１を制御する。第１照明シーンでは、光源制御部１２は、光源光の発光状態を、第１発光状態と第１発光状態よりも刺激純度及び光量の少なくとも一方が小さい第２発光状態との間で、第１周期で反復して変化させるように光源部１１を制御する。第２照明シーンでは、光源制御部１２は、光源光の発光状態を一定にする、又は、光源光の発光状態を、第１発光状態と第２発光状態との間で、第１周期よりも長い第２周期で反復して変化させるように光源部１１を制御する。 [Effects, etc.]
As described above, the lighting system 1 according to the present embodiment includes a first light source 11a that emits the first light and a second light source 11b that emits the second light having a chromaticity different from that of the first light. And a light source control unit 12 that controls the light emission state of the light source light emitted by the light source unit 11. The light source control unit 12 controls the light source unit 11 so as to switch between the first lighting scene and the second lighting scene. In the first lighting scene, the light source control unit 12 sets the light source light emission state between the first light emission state and the second light emission state in which at least one of the stimulus purity and the amount of light is smaller than the first light emission state. The light source unit 11 is controlled so as to be repeatedly changed in a cycle. In the second lighting scene, the light source control unit 12 makes the light source light emission state constant, or sets the light source light emission state between the first light emission state and the second light emission state from the first cycle.

Therefore, it becomes easier to induce the user to breathe. As a result, the intellectual productivity of the user can be improved by relaxing the user more effectively.
　また、光源制御部１２は、ユーザの操作により入力された、第１照明シーンと第２照明シーンとの切り替えタイミング、並びに、第１照明シーン及び第２照明シーンの継続時間の少なくとも一方を示す第２操作情報を取得する。光源制御部１２は、第２操作情報に基づいて第１照明シーンと第２照明シーンとを切り替えるように光源部１１を制御する。 Further, the light source control unit 12 indicates at least one of the switching timing between the first lighting scene and the second lighting scene and the duration of the first lighting scene and the second lighting scene, which are input by the user's operation. 2 Acquire operation information. The light source control unit 12 controls the light source unit 11 so as to switch between the first lighting scene and the second lighting scene based on the second operation information.
　これにより、ユーザが任意のタイミングで第１照明シーンと第２照明シーンとを切り替えられるため、光源制御部１２は、ユーザの知的作業時の体調及び気分等に応じたタイミングで第１照明シーンと第２照明シーンとを切り替えることができる。よって、より効果的なタイミングでユーザをリラックスさせるシーンと知的作業に集中させるシーンとを切り替えることができるため、ユーザの知的生産性を向上させることができる。 As a result, the user can switch between the first lighting scene and the second lighting scene at an arbitrary timing, so that the light source control unit 12 can switch the first lighting scene at a timing according to the physical condition and mood of the user during intellectual work. And the second lighting scene can be switched. Therefore, it is possible to switch between a scene in which the user is relaxed and a scene in which the user is focused on intellectual work at a more effective timing, so that the intellectual productivity of the user can be improved.
　また、照明システム１は、第２操作情報を入力する操作をユーザから受け付ける第２入力部２２をさらに備える。光源制御部１２は、第２入力部２２においてユーザの操作により入力された、第２操作情報を取得し、取得した第２操作情報に基づいて第１照明シーンと第２照明シーンとを切り替えるように光源部１１を制御する。 Further, the lighting system 1 further includes a second input unit 22 that receives an operation for inputting the second operation information from the user. The light source control unit 12 acquires the second operation information input by the user's operation in the second input unit 22, and switches between the first lighting scene and the second lighting scene based on the acquired second operation information.

　また、照明システム１は、センサ４０から取得した情報に基づいて、光源光の照射範囲の周囲の人の存在を特定するセンシング部１５をさらに備える。光源制御部１２は、センシング部１５が、人の存在を特定したタイミングで、第２照明シーンでの光源部１１の制御を開始する。 Further, the lighting system 1 further includes a sensing unit 15 that identifies the presence of a person around the irradiation range of the light source light based on the information acquired from the sensor 40. The light source control unit 12 starts controlling the light source unit 11 in the second lighting scene at the timing when the sensing unit 15 identifies the existence of a person.
　これにより、ユーザ等の人が操作することなく、第２照明シーンが開始することで、ユーザの知的生産性を向上させることができる照明環境が自動的に整えられる。 As a result, the lighting environment that can improve the intellectual productivity of the user is automatically prepared by starting the second lighting scene without any operation by the user or the like.
