[2. Lighting Control Procedure] Next, a lighting control procedure as an example of the control procedure of the lighting system 10 according to the present embodiment will be described with reference to the drawings.

FIG. 4 is a flowchart showing a lighting control procedure according to the present embodiment. FIG. 5 is a graph showing an example of the time waveform of the illuminance of the first lighting fixture 31 and the second lighting fixture 32 in the lighting control sequence according to the present embodiment. Graphs (a) and (b) show the time waveforms of the illuminance of the first lighting fixture 31 and the second lighting fixture 32, respectively.

As shown in FIG. 4 , the lighting control sequence includes a first lighting operation S11 and a second lighting operation S12. The first sound operation S13 may be included in the lighting control sequence.

In the lighting control sequence, the first lighting operation S11 is first performed. The first lighting operation S11 is an operation of gradually increasing the illuminance of the second lighting fixture 32 to a predetermined first lighting illuminance. In the present embodiment, by the second control circuit 22, the illuminance of the second lighting fixture 32 linearly increases to the first lighting illuminance during the first lighting time from time T11 to time T12. Moreover, when the lighting system 10 is equipped with the some 2nd lighting fixture 32, in the 1st lighting operation S11, the some 2nd lighting fixture 32 is controlled simultaneously. There is no particular limitation on the manner of increasing the illuminance of the second lighting fixture 32 . The way of increasing the illuminance of the second lighting fixture 32 may be, for example, a substantially continuous increase or a stepwise increase. In addition, the rising mode of the illuminance of the second lighting fixture 32 may not be linear, but may be curved. In addition, the first lighting illuminance may be 100% of the rated illuminance of the second lighting fixture 32, or may be less than 100%.

As the second lighting fixture 32 , for example, when a lighting fixture arranged around the bed 95 is used, the illuminance can be increased while suppressing strong stimulation to the user sleeping on the bed 95 . Therefore, the user can be awakened while suppressing an uncomfortable feeling to the user.

At time T13 when the first standby time elapses from time T12 when the first lighting operation S11 ends, the second lighting operation S12 is performed. Here, the first standby time can be appropriately set so that the user can be prevented from feeling abruptly brightened when the second lighting operation S12 starts. For example, the first standby time may be greater than zero and less than or equal to about 10 minutes, and may also be zero when the stimulation to the user is sufficiently small when the second lighting operation S12 starts. In addition, as the first lighting time and the second lighting time described later are longer, the illuminance of the first lighting fixture 31 and the second lighting fixture 32 can be gradually increased. Therefore, the longer the first lighting time and the second lighting time are, the shorter the first standby time is. In addition, the first standby time may be set to a desired time by the user.

The second lighting operation S12 is an operation of gradually increasing the illuminance of the first lighting fixture 31 to a predetermined second lighting illuminance. In the present embodiment, the illuminance of the first lighting fixture 31 is increased in a curve shape to the second lighting illuminance by the first control circuit 21 during the second lighting time from time T13 to time T14. Moreover, when the lighting system 10 is provided with the some 1st lighting fixture 31, in the 2nd lighting operation S12, the some 1st lighting fixture 31 is controlled simultaneously. The manner of increasing the illuminance of the first lighting fixture 31 is not particularly limited. The way of increasing the illuminance of the first lighting fixture 31 may be, for example, a substantially continuous increase or a stepwise increase. In addition, the way of increasing the illuminance of the first lighting fixture 31 may not be a curve, but a straight line.

As the first lighting fixture 31 , for example, when a lighting fixture disposed directly above or near the bed 95 is used, the user who falls asleep on the bed 95 is strongly stimulated. Even in such a case, by gradually increasing the illuminance of the first lighting fixture 31, it is possible to wake up the user while suppressing discomfort to the user.

Therefore, in the lighting system 10, the illuminance of the first lighting fixture 31 and the second lighting fixture 32, which stimulate the user who is falling asleep, can be increased, respectively. Therefore, it is possible to realize a wake-up function that suppresses discomfort to the user. Furthermore, in the present embodiment, the first lighting fixture 31 and the second lighting fixture 32 may not be included in the same housing. Therefore, the degree of freedom of adjustment for the light stimulation to the user is increased, so that more Comfortable wake-up function.

In the lighting system 10 according to the present embodiment, when the second lighting operation S12 is started, that is, when the first lighting fixture 31 is turned on, the light stimulus rapidly rises, which appears to the user. Situations that cause discomfort. Therefore, in the present embodiment, the first lighting fixture 31 performs lighting control so as to suppress discomfort to the user. This lighting control will be described with reference to the drawings.

FIG. 6 is an enlarged view around time T13 of the graph shown in FIG. 5 . As shown in FIG. 6 , in the second lighting operation, the illuminance at the moment when the first lighting fixture 31 is initially turned on is set as the minimum illuminance. After time T13 , the illuminance of the first lighting fixture 31 is increased according to the time resolution ΔT of the first control circuit 21 .

In the present embodiment, in the second lighting operation S12, the total illuminance of the first lighting fixture 31 and the second lighting fixture 32 when the first lighting fixture 31 is lit at the minimum illuminance is greater than or equal to the first lighting illuminance 97% and less than or equal to 103%. In the example shown in FIG. 6 , the minimum illuminance of the first lighting fixture 31 is less than or equal to 3% of the first lighting illuminance. Thereby, the change in the illuminance of the light emitted from the entire lighting system 10 at the moment when the first lighting fixture 31 is turned on with the minimum illuminance can be suppressed very small. Therefore, discomfort to the user can be suppressed.

In the example shown in FIG. 6 , the minimum illuminance of the first lighting fixture 31 is less than or equal to 3% of the first lighting illuminance, and the illuminance of the second lighting fixture 32 when the first lighting fixture 31 is lit with the minimum illuminance is First light illumination.

In addition, in the example shown in FIG. 6, although the illuminance of the 2nd illuminator 32 is maintained at the state of the 1st lighting illuminance and the 1st illuminator 31 is turned on, but the 1st illuminator may be made 31 When lighting is performed, the illuminance of the second lighting fixture 32 is reduced to be lower than the first lighting illuminance. Such an operation example will be described with reference to the accompanying drawings.

FIG. 7 is a graph showing another example of the time waveform of the illuminance of the first lighting fixture 31 and the second lighting fixture 32 in the lighting control sequence according to the present embodiment. FIG. 7 shows an enlarged view of the graph in the vicinity of time T13 when the first lighting fixture 31 is turned on. The enlarged view (a) and the enlarged view (b) show the time waveforms of the illuminance of the first lighting fixture 31 and the second lighting fixture 32, respectively.

In the example shown in FIG. 7 , in the second lighting operation S12, when the first lighting fixture 31 is turned on with the minimum illuminance, the illuminance of the second lighting fixture 32 is decreased at the minimum illuminance almost at the same time. . Even in this example, the first lighting fixture 31 and the second lighting fixture 32 are controlled to be the first lighting fixture 31 and the second lighting fixture 31 when the first lighting fixture 31 is lit with the minimum illuminance in the second lighting operation S12. The total illuminance of the two lighting fixtures 32 is greater than or equal to 97% and less than or equal to 103% of the first lighting illuminance. Thereby, the change in the illuminance of the light emitted from the entire lighting system 10 at the moment when the first lighting fixture 31 is turned on with the minimum illuminance can be suppressed very small. Therefore, discomfort to the user can be suppressed.

Returning to FIG. 4 , after the first lighting operation S11 is completed, the first sound operation S13 may be performed in parallel with the second lighting operation S12 . The first audio operation S13 is an operation of gradually increasing the volume output from the audio device 33 from zero to a predetermined first volume. In the present embodiment, by the sound control circuit 23, the sound volume of the sound equipment 33 is gradually increased to the first sound volume at the second lighting time from the time T13 to the time T14. The sound output from the audio equipment 33 is not particularly limited. In the first audio operation S13 , music may also be output from the audio equipment 33 . The type of music may be appropriately set by the user, or may be predetermined music. As the music output in the first sound operation S13, for example, cheerful music can be used to wake up the user from sleep in a pleasant mood. In addition, the volume output from the audio device 33 when the first audio operation starts may not be zero, but may be a volume lower than the first volume.

In addition, in the first lighting operation S11 and the second lighting operation S12, the color temperature of each lighting fixture may be gradually changed. For example, the color temperature of each lighting fixture can also be gradually increased. Accordingly, a more comfortable awakening can be achieved.

[3. Lighting-off control procedure] Next, a light-off control procedure of another example of the control procedure of the lighting system 10 according to the present embodiment will be described with reference to the drawings.

FIG. 8 is a flowchart showing a light-off control procedure according to the present embodiment. FIG. 9 is a graph showing an example of the time waveform of the illuminance of the first lighting fixture 31 and the second lighting fixture 32 in the turn-off control sequence according to the present embodiment. Graphs (a) and (b) show the time waveforms of the illuminance of the first lighting fixture 31 and the second lighting fixture 32, respectively.

As shown in FIG. 8 , the light-off control sequence includes a first light-off operation S21 and a second light-off operation S22. In addition, the second sound operation S23 may be included in the light-off control sequence.

In the light-off control sequence, the first light-off operation S21 is first performed. The first turn-off operation S21 is an operation of gradually reducing the illuminance of the first lighting fixture 31 to a predetermined first turn-off illuminance. In the present embodiment, by the first control circuit 21, the illuminance of the first lighting fixture 31 decreases to the first turn-off illuminance in a curve shape during the first turn-off time from time T21 to time T22. Moreover, when the lighting system 10 is provided with the some 1st lighting fixture 31, in the 1st light-off operation S21, the some 1st lighting fixture 31 is controlled simultaneously. The method of reducing the illuminance of the first lighting fixture 31 is not particularly limited. The reduction method of the illuminance of the first lighting fixture 31 may be, for example, a substantially continuous reduction, or a stepwise reduction. In addition, the way of reducing the illuminance of the first lighting fixture 31 may not be a curve, but a straight line. In the present embodiment, although the first turn-off illuminance is greater than zero, the first turn-off illuminance may also be zero.

As the first lighting fixture 31 , when, for example, a lighting fixture disposed directly above or near the bed 95 is used, in the first light-off operation S21 , the user who is falling asleep on the bed 95 can gradually Slowly weaken stronger stimuli. Therefore, it is possible to suppress the uncomfortable feeling given to the user, and to gradually induce the user to fall asleep.

The second sound operation S23 may also be performed in parallel with the first light-off operation S21. The second audio operation S23 is an operation of gradually reducing the volume output from the audio device 33 to a predetermined second volume. In the present embodiment, by the audio control circuit 23, the volume of the audio equipment 33 is gradually decreased in the first light-off time from the time T21 to the time T22. The sound output from the audio equipment 33 is not particularly limited. In the second audio operation S23 , music may also be output from the audio device 33 . The type of music may be appropriately set by the user, or may be predetermined music. As the music to be output in the second sound operation S23, for example, quiet music that can urge the user to fall asleep in a pleasant mood can be used. In addition, in the present embodiment, the volume of the audio device 33 is set to zero at time T22, but the volume may not be zero as long as sleep can be promoted.

At time T23 when the second standby time elapses from time T22 when the first light-off operation S21 and the second sound operation S23 end, the second light-off operation S22 is performed. Here, the second standby time can be appropriately set so that the user can be prevented from feeling abruptly darkened when the second light-off operation S22 starts. For example, the second standby time may be greater than zero and less than 10 minutes, and may also be zero when the stimulation to the user is sufficiently small when the second light-off operation S22 starts. In addition, as the first light-off time and the second light-off time described later are longer, the illuminance of the first lighting fixture 31 and the second lighting fixture 32 can be gradually decreased. Therefore, the longer the first turn-off time and the second turn-off time are, the shorter the second standby time is. In addition, the second standby time may be set by the user to a desired time.

The second light-off operation S22 is an operation for gradually reducing the illuminance of the second lighting fixture 32 from the predetermined second light-off illuminance. In this embodiment, the illuminance of the second lighting fixture 32 decreases linearly from the second light-off illuminance during the second light-off time from the time T23 to the time T24 by the second control circuit 22 . In the present embodiment, the second light-off illuminance is zero. Moreover, when the lighting system 10 is provided with the some 2nd lighting fixture 32, in the 2nd light-off operation S22, the some 2nd lighting fixture 32 is controlled simultaneously. The method of reducing the illuminance of the second lighting fixture 32 is not particularly limited. The way of reducing the illuminance of the second lighting fixture 32 may be, for example, a substantially continuous decrease or a stepwise decrease. In addition, the decreasing manner of the illuminance of the second lighting fixture 32 may not be linear, but may be curvilinear.

As the second lighting fixture 32, for example, when a lighting fixture arranged around the bed 95 is used, a relatively weak stimulus to the user who is about to fall asleep on the bed 95 can be gradually weakened. Therefore, by gradually decreasing the illuminance, the user can be urged to sleep while suppressing discomfort to the user.

Therefore, the illuminance of the first lighting fixture 31 and the second lighting fixture 32, which stimulate the user who is about to fall asleep, can be reduced, respectively. Therefore, it is possible to realize a sleep-onset function that suppresses discomfort to the user. Furthermore, in the present embodiment, the first lighting fixture 31 and the second lighting fixture 32 may not be included in the same housing, and since the user has a high degree of freedom in adjusting the light stimulation, it is possible to achieve a more comfortable sleep. Features.

In the lighting system 10 according to the present embodiment, when the second light-off operation S22 is started, that is, when the light-off of the second lighting fixture 32 is started, there is a sudden change in the stimulus of light, and the use of cause discomfort. Therefore, in the present embodiment, the second lighting fixture 32 is controlled to be turned off in order to suppress discomfort to the user. This light-off control will be described with reference to the drawings.

FIG. 10 is an enlarged view around time T23 of the graph shown in FIG. 9 . The enlarged view (a) and the enlarged view (b) show the time waveforms of the illuminance of the first lighting fixture 31 and the second lighting fixture 32, respectively.

As shown in FIG. 10 , in the second light-off operation S22 , the amount of change in the illuminance at the moment when the illuminance of the second lighting fixture 32 is first decreased is set as the minimum amount of change. After time T23 , the illuminance of the second lighting fixture 32 is decreased according to the time resolution ΔT of the second control circuit 22 . In addition, the time resolution ΔT of the second control circuit 22 may be the same as the time resolution ΔT of the first control circuit 21 or may be different.

In the present embodiment, in the second light-off operation S22, the total illuminance of the first lighting fixture 31 and the second lighting fixture 32 when the illuminance of the second lighting fixture 32 is reduced by the minimum change amount is equal to or greater than the first light-off 97% and less than or equal to 103% of the total illuminance of the lamp illuminance and the second light-off illuminance. In the example shown in FIG. 10 , the minimum change amount of the second lighting fixture 32 is less than or equal to 3% of the total illuminance of the first turn-off illuminance and the second turn-off illuminance. According to this, the change in the illuminance of the light emitted from the entire lighting system 10 at the moment when the illuminance of the second lighting fixture 32 decreases by the smallest amount of change can be suppressed very small. Therefore, discomfort to the user can be suppressed.

In the example shown in FIG. 10 , the minimum change amount of the second lighting fixture 32 is less than or equal to 3% of the total illuminance of the first light-off illuminance and the second light-off illuminance, and the illuminance of the second lighting fixture 32 is changed to the minimum The illuminance of the first lighting fixture 31 when the amount decreases is the first light-off illuminance.

Furthermore, in the example shown in FIG. 10 , the illuminance of the second lighting fixture 32 is decreased while the illuminance of the first lighting fixture 31 is maintained at the first light-off illuminance, but the second lighting fixture 32 may be When the illuminance decreases, the illuminance of the first lighting fixture 31 is made higher than the first light-off illuminance. Even in this case, in the second light-off operation S22, the first lighting fixture 31 and the second lighting fixture 32 are controlled to be the first lighting fixture 32 when the illuminance of the second lighting fixture 32 is reduced by the minimum change amount. The total illuminance of the lighting fixture 31 and the second lighting fixture 32 is greater than or equal to 97% and less than or equal to 103% of the total illuminance of the first light-off illuminance and the second light-off illuminance. Thereby, the change in the illuminance of the light emitted from the entire lighting system 10 at the moment when the first lighting fixture 31 is turned on with the minimum illuminance can be suppressed very small. Therefore, discomfort to the user can be suppressed.

In addition, in the first turning-off operation S21 and the second turning-off operation S22, the color temperature of each lighting fixture may be gradually changed. For example, the color temperature of each lighting fixture can also be gradually decreased. Therefore, it is possible to promote more comfortable sleep.
