[2. Lighting control sequence] Next, the lighting control sequence as an example of the control sequence 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 a 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 lighting control sequence may include a first acoustic operation S13.

In the lighting control sequence, the first lighting operation S11 is performed first. The first lighting operation S11 is an operation for gradually increasing the illuminance of the second lighting fixture 32 to a predetermined first lighting illuminance. In this embodiment, by the second control circuit 22, the illuminance of the second lighting fixture 32 rises linearly to the first illuminance during the first lighting time from time T11 to time T12. When the lighting system 10 includes a plurality of second lighting fixtures 32, the plurality of second lighting fixtures 32 are simultaneously controlled in the first lighting operation S11. 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 rise or a stepwise rise. In addition, the manner of increasing 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% or less than 100% of the rated illuminance of the second lighting fixture 32.

As the second lighting fixture 32, for example, when a lighting fixture arranged around the bed 95 is used, it is possible to increase the illuminance while suppressing strong stimulation to a user sleeping on the bed 95. Therefore, it is possible to both suppress the discomfort to the user and wake the user.

At the time T13 when the first standby time elapses from the 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 restrained from feeling a sudden brightening at the start of the second lighting operation S12. The first standby time may be, for example, a time greater than zero and about 10 minutes or less. In a case where the stimulation to the user is sufficiently small at the start of the second lighting operation S12, the first standby time may also be zero. In addition, the longer the first lighting time and the second lighting time described later, the illuminance of the first lighting fixture 31 and the second lighting fixture 32 can gradually rise. Therefore, the longer the first lighting time and the second lighting time, the shorter the first standby time becomes. The first standby time may be set to a desired time by the user.

The second lighting operation S12 is an operation for 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 device 31 rises in a curve to the second lighting illuminance during the second lighting time from time T13 to time T14 by the first control circuit 21. When the lighting system 10 includes a plurality of first lighting fixtures 31, the plurality of first lighting fixtures 31 are simultaneously controlled in the second lighting operation S12. 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 rise or a step-like rise. In addition, the manner of increasing the illuminance of the first lighting fixture 31 may not be a curved shape, but may be a linear shape.

As the first lighting device 31, for example, when a lighting device arranged directly above or in the vicinity of the bed 95 is used, a strong stimulus will be given to a user who sleeps on the bed 95. Even in this case, it is possible to wake up the user while suppressing discomfort to the user by gradually increasing the illuminance of the first lighting fixture 31.

Therefore, in the lighting system 10, it is possible to increase the illuminance of the first lighting fixture 31 and the second lighting fixture 32, which stimulate the user who is sleeping. Therefore, a wake-up function that suppresses discomfort to the user can be realized. Furthermore, in this embodiment, the first lighting fixture 31 and the second lighting fixture 32 may not be included in the same frame. Therefore, for the light stimulus provided to the user, the degree of freedom of adjustment 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, it will appear to the user as the stimulus of light rises sharply. Conditions 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 near 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 first turned on is set to the minimum illuminance. After time T13, the illuminance of the first lighting fixture 31 is increased in accordance with the time resolution ΔT of the first control circuit 21.

In this 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 equal to or greater than 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 illuminance of the first lighting. Accordingly, it is possible to suppress a change in the illuminance of the light emitted from the entire lighting system 10 at the moment when the first illuminating device 31 is lit at the minimum illuminance. Therefore, it is possible to suppress discomfort to the user.

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 lighting is The first point of illumination.

In the example shown in FIG. 6, although the first lighting fixture 31 is turned on while the illuminance of the second lighting fixture 32 is maintained at the first lighting illuminance, the first lighting fixture may be turned on. When lighting 31, the illuminance of the second lighting fixture 32 is reduced to be less than the first lighting illuminance. This operation example will be described with reference to the drawings.

FIG. 7 is a graph showing another example of time waveforms 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 is an enlarged view of a graph around time T13 when the first lighting fixture 31 is turned on. The enlarged view (a) and the enlarged view (b) show 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 reduced at the same time with the minimum illuminance. . Even in this example, the first lighting fixture 31 and the second lighting fixture 32 are controlled so that in the second lighting operation S12, the first lighting fixture 31 and the first lighting fixture 31 when the first lighting fixture 31 is lit with the minimum illuminance The total illuminance of the two lighting appliances 32 is greater than or equal to 97% and less than or equal to 103% of the first lighting illuminance. Accordingly, it is possible to suppress a 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. Therefore, it is possible to suppress discomfort to the user.

Returning to FIG. 4, after the first lighting operation S11 is completed, the first acoustic operation S13 may also be performed in parallel with the second lighting operation S12. The first sound operation S13 is an operation of gradually increasing the volume output from the sound device 33 from zero to a predetermined first volume. In the present embodiment, the volume of the audio device 33 is gradually increased to the first volume by the audio control circuit 23 during the second lighting time from time T13 to time T14. The sound output from the audio equipment 33 is not particularly limited. In the first audio operation S13, music can 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 output in the first audio operation S13, for example, cheerful music may be used to make the user wake up from sleep happily. In addition, the volume output from the audio device 33 when the first audio operation is started 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 device may be gradually changed. For example, the color temperature of each lighting device can also be gradually increased. Accordingly, a more comfortable wake-up can be achieved.

[3. Light-off control sequence] Next, the light-off control sequence of another example of the control sequence 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 sequence according to the present embodiment. FIG. 9 is a graph showing an example of a time waveform of the illuminance of the first lighting fixture 31 and the second lighting fixture 32 in the light-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 first light-off operation S21 and the second light-off operation S22 are included in the light-off control sequence. 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 performed first. The first light-off operation S21 is an operation of gradually reducing the illuminance of the first lighting fixture 31 to a predetermined first light-off illuminance. In this embodiment, by the first control circuit 21, the illuminance of the first lighting fixture 31 is reduced to a first extinguished illuminance in a curve shape during a first extinguished time from time T21 to time T22. When the lighting system 10 includes a plurality of first lighting fixtures 31, the plurality of first lighting fixtures 31 are simultaneously controlled in the first light-off operation S21. The manner of reducing the illuminance of the first lighting fixture 31 is not particularly limited. The method for reducing the illuminance of the first lighting fixture 31 may be, for example, a substantially continuous decrease or a stepwise decrease. In addition, the manner of reducing the illuminance of the first lighting fixture 31 may not be curved, but may be linear. In this embodiment, although the first light-off illuminance is greater than zero, the first light-off illuminance may be zero.

As the first lighting fixture 31, for example, in the case where a lighting fixture arranged directly above or near the bed 95 is used, in the first light-off operation S21, the user who is sleeping on the bed 95 can gradually The ground slowly weakens the stronger stimulus. Therefore, it is possible to suppress discomfort to the user, and to gradually urge 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 sound operation S23 is an operation of gradually reducing the volume output from the sound device 33 to a predetermined second volume. In this embodiment, the volume of the audio device 33 is gradually reduced by the audio control circuit 23 during the first light-off time from time T21 to time T22. The sound output from the audio equipment 33 is not particularly limited. In the second audio operation S23, music can 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 output in the second audio operation S23, for example, quiet music that can urge the user to sleep happily can be adopted. In addition, in this embodiment, although the volume of the audio device 33 is set to zero at time T22, the volume may not be zero as long as it can promote sleep.

At the time T23 when the second standby time has elapsed since the time T22 when the first light-off operation S21 and the second sound operation S23 are completed, the second light-off operation S22 is performed. Here, the second standby time can be appropriately set so that the user can be suppressed from feeling a sudden darkening at the start of the second light-off operation S22. The second standby time may be, for example, a time greater than zero and less than about 10 minutes. In a case where the stimulation to the user is sufficiently small at the start of the second light-off operation S22, the second standby time may also be zero. In addition, the longer the first light-off time and the second light-off time to be described later, the illuminance of the first lighting device 31 and the second lighting device 32 can be gradually reduced. Therefore, the longer the first light-off time and the second light-off time, the shorter the second standby time can be. The second standby time may be set to a desired time by the user.

The second light-off operation S22 is an operation for gradually reducing the illuminance of the second lighting fixture 32 from a predetermined second light-off illuminance. In this embodiment, the illuminance of the second lighting fixture 32 decreases linearly from the second extinguished illuminance during the second extinguished time from the time T23 to the time T24 by the second control circuit 22. In this embodiment, the second light-off illuminance is zero. When the lighting system 10 includes a plurality of second lighting fixtures 32, the plurality of second lighting fixtures 32 are simultaneously controlled in the second light-off operation S22. The manner of reducing the illuminance of the second lighting fixture 32 is not particularly limited. The method for reducing the illuminance of the second lighting fixture 32 may be, for example, a substantially continuous decrease or a stepwise decrease. The method of decreasing the illuminance of the second lighting fixture 32 may not be linear, but may be curved.

As the second lighting fixture 32, for example, when a lighting fixture arranged around the bed 95 is used, a relatively weak stimulus for a user who is going to sleep on the bed 95 can be gradually weakened. Therefore, by gradually reducing the illuminance, it is possible to urge the user to go to sleep while suppressing discomfort to the user.

Therefore, the illuminance of the first luminaire 31 and the second luminaire 32 which provide stimulation to a user who is about to fall asleep can be reduced, respectively. Therefore, a sleep function that suppresses discomfort to the user can be achieved. Moreover, in the present embodiment, the first lighting device 31 and the second lighting device 32 may not be included in the same frame, and since the degree of freedom of adjustment that brings light stimulation to the user is high, it is possible to achieve 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, a sudden change in the light stimulus will occur for use. The situation that the person brings discomfort. Therefore, in the present embodiment, the second lighting fixture 32 performs a light-off control so as to suppress discomfort to the user. The light-off control will be described with reference to the drawings.

FIG. 10 is an enlarged view near time T23 of the graph shown in FIG. 9. The enlarged view (a) and the enlarged view (b) show 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 luminaire 32 is first reduced is set to the minimum amount of change. After time T23, the illuminance of the second luminaire 32 is reduced in accordance with the time resolution ΔT of the second control circuit 22. The time resolution ΔT of the second control circuit 22 may be the same as or different from the time resolution ΔT of the first control circuit 21.

In the present embodiment, in the second light-off operation S22, when the illuminance of the second luminaire 32 is reduced by a minimum change amount, the total illuminance of the first luminaire 31 and the second luminaire 32 is greater than or equal to the first extinguishment The total illuminance of the lamp illuminance and the second extinguished illuminance is 97% to 103%. 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 extinguished illuminance and the second extinguished illuminance. According to this, it is possible to suppress a 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 with a minimum change amount to be very small. Therefore, it is possible to suppress discomfort to the user.

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 lighting-off illuminance and the second lighting-off illuminance. The illuminance of the first lighting fixture 31 when the amount is reduced is the first extinguished illuminance.

In the example shown in FIG. 10, although the illuminance of the first luminaire 31 is maintained at the first extinguished illuminance and the illuminance of the second luminaire 32 is decreased, the second luminaire 32 may be reduced. When the illuminance decreases, the illuminance of the first lighting fixture 31 is higher than the first extinguished 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 so that the first time when the illuminance of the second lighting fixture 32 is reduced by a minimum change amount. The total illuminance of the lighting device 31 and the second lighting device 32 is greater than or equal to 97% and less than or equal to 103% of the total illuminance of the first extinguished illuminance and the second extinguished illuminance. Accordingly, it is possible to suppress a 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. Therefore, it is possible to suppress discomfort to the user.

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