Japanese Unexamined Patent Publication No. 5-3874

However, in the conventional control system as a biological rhythm adjusting device, even if the biological rhythm can be adjusted according to the change of the environmental information, the living rhythm cannot be adjusted if the user's condition and lifestyle change. There is a fear. Therefore, even if it can be set according to the state of the user and the lifestyle, it takes time and effort to set it.

Therefore, it is an object of the present disclosure to provide a control system and a lighting system that can easily set supplementary light conditions according to a user's condition and lifestyle.

(Knowledge that led to the invention)
In recent years, it is known that biological rhythms are synchronized with the amount of light received by bath light. For example, biological rhythms include circadian rhythms with a cycle of about one day. Circadian rhythms include fluctuations in body temperature, sleep-wake cycles, and fluctuations in hormone secretion.

For example, users living in facilities for the elderly, etc., go outdoors less frequently, so the chances of being exposed to natural light during the day are reduced, and the amount of light received per day tends to be insufficient. In this case, the circadian rhythm with a cycle of about one day may not be adjusted, and good quality sleep may not be obtained at night.

It has been reported that the prevalence and symptoms of dementia worsen if good sleep is not obtained. Therefore, it is very important to illuminate the user and adjust the circadian rhythm by installing a lighting device in such a facility for the elderly in order to improve the quality of life of the user.

Generally, it is useful to expose the user to light with a higher illuminance than normal lighting as supplementary light. For example, the supplementary light can be considered based on the amount of received light obtained by multiplying the intensity of the light and the time, but the general supplementary light for the elderly is often 10,000 lpxH or more. However, this is just a guide, and originally, a specialist in sleep and psychiatry, or a specialist who has correct knowledge about supplementation, sets the ideal supplementation conditions according to the living environment of the user. There is a need. However, there are few specialists who have correct knowledge, and those who care for the elderly have a heavy burden on the care itself, and it is difficult to consider the conditions for supplementation according to the user's condition. Further, when the user is individually supplemented with light, it is assumed that the user is used in a living room or the like, but the time spent in the room and the lighting time during which the light can be supplemented differ depending on the lifestyle of each user. It is possible to set the supplementary light according to the user's condition and lifestyle, but it takes time and effort to set the supplementary light.

Therefore, the present disclosure provides a control system and a lighting system that can easily set the supplementary light conditions according to the user's condition and lifestyle.

Hereinafter, embodiments will be described with reference to the drawings. It should be noted that all of the embodiments described below show comprehensive or specific examples. Numerical values, shapes, materials, components, arrangement positions and connection forms of components, steps, order of steps, etc. shown in the following embodiments are examples, and are not intended to limit the present disclosure. Further, among the components in the following embodiments, the components not described in the independent claims will be described as arbitrary components.

Note that each figure is a schematic diagram and is not necessarily exactly illustrated. Further, in each figure, substantially the same configuration may be designated by the same reference numerals, and duplicate description may be omitted or simplified.

Hereinafter, the control system and the lighting system according to the embodiment of the present disclosure will be described.

(Embodiment 1)
<Configuration: Lighting system 10>
FIG. 1 is a schematic view showing the lighting system 10 according to the first embodiment.

As shown in FIG. 1, in the lighting system 10, a user who needs supplementary light is exposed to light as supplementary light in addition to the light normally received, so that the user secures the amount of light received per day. Here, supplementary light is an illuminance 1.2 times or more the general illuminance (illuminance recommended by JIS Z 9110: 2011 general rules of lighting standards, etc.) in order to maintain and promote biological rhythm. It is to expose the user to the light of.

For example, in order to supplement the amount of received light that is less than the amount of received light required for one day, the user is exposed to light having an illuminance of 1.2 times or more the general illuminance. Specifically, when the lighting device 30 installed in the room is normally lit, the control system 20 has an illuminance 1.2 times or more higher than the illuminance value at the time of normal lighting. Is lit, or another illuminating device 30 is further lit. As a result, the user is exposed to light as supplementary light. When the lighting device 30 is not lit, the lighting system 10 turns on the lighting device 30 to expose the user to light as supplementary light.

Elderly people tend to sleep in bed for a longer period of time. Therefore, when the lighting system 10 is applied to a facility for the elderly or the like, the general illuminance is horizontal illuminance, so it is necessary to replace it with vertical illuminance. For example, if the horizontal illuminance of a dining room in a medical facility is 300 lpx, it becomes 150 lpx when replaced with the vertical illuminance. If the horizontal illuminance of the hospital room is 100 lpx, it becomes 50 lpx when replaced with the vertical illuminance. Therefore, even if the user is exposed to light as supplementary light based on the horizontal illuminance, the user may not have enough light received per day. Therefore, when the user is an elderly person, the supplementary light condition is considered based on the vertical illuminance.

FIG. 2 is a block diagram showing the lighting system 10 according to the first embodiment.

As shown in FIG. 2, the lighting system 10 includes a control system 20 and a lighting device 30.

[Control system 20]
The control system 20 controls the lighting mode of one or more lighting devices 30 in order to expose the user to light as supplementary light. The control system 20 includes a measuring device 21, a processing unit 22, and a control unit 23. In the present embodiment, the control system 20 has the measuring device 21, but it is not an essential configuration requirement and does not have to have the measuring device 21. The measuring device 21, the processing unit 22, and the control unit 23 may be separate bodies or integrated devices.

The measuring device 21 has a first measuring unit 21a.

The first measurement unit 21a is, for example, an electroencephalograph, a heart rate monitor, a sphygmomanometer, an eye movement measurement device 21, an imaging device, or the like. The first measurement unit 21a measures the user's body. The user's body (that is, user information) is the user's brain wave, heart rate, blood pressure, eye movement, and the like. The first measurement unit 21a can communicate with the determination unit 22a by wire or wirelessly. The first measurement unit 21a outputs the measured user information about the user's body to the determination unit 22a.

The processing unit 22 is one microcontroller having a determination unit 22a and a setting unit 22b. The determination unit 22a and the setting unit 22b may be realized by separate microcontrollers.

The determination unit 22a acquires user information about the user's body measured by the measuring device 21, and determines the user's state based on the acquired user information. The user's state is a state of good sleep, a state of poor sleep, a state of depression, and the like. In the present embodiment, as the user's state, a state of good sleep and a state of poor sleep will be mainly described. The determination unit 22a outputs the determination result of determining the user's state to the setting unit 22b.

The setting unit 22b sets the supplementary light condition according to the user's state based on the determination result determined by the determination unit 22a.

Specifically, when the determination result determined by the determination unit 22a is a state of good sleep, the setting unit 22b sets a supplementary light condition suitable for the state of good sleep. For example, when the amount of light received is less than the amount required for one day, the setting unit 22b raises the illuminance of the lighting device 30 so as to be 1.2 times or more the normal lighting. When the amount of light received per day is satisfied, the illuminance of the lighting device 30 is lowered or the lighting device 30 is turned off. The setting unit 22b may simply cause the lighting device 30 to perform normal illumination when the amount of light received per day is satisfied.

Further, when the determination result determined by the determination unit 22a is a sleep deterioration state, the setting unit 22b sets a supplementary light condition suitable for the sleep deterioration state. For example, the setting unit 22b raises the illuminance of the lighting device 30 according to the supplementary light condition so as to satisfy the amount of light received required for one day. Here, the condition of the supplementary light is the lighting time, the lighting time, the illuminance, the hue of the light by adjusting the toning or the wavelength, and the combination thereof as the light emitted by the lighting device 30.

The setting unit 22b sets the lighting time of the supplementary light by the lighting device 30 to 7 hours or more in a day (or 24 hours) as a condition of the supplementary light. "7 hours or more" may be a continuous time or a discrete integrated time. In particular, the setting unit 22b preferably sets the lighting time zone of the supplementary light to 10 hours or more.

Further, the setting unit 22b sets the lighting time zone of the supplementary light so as to include one hour or more of the time zone after 17:00 as a condition of the supplementary light. Specifically, the setting unit 22b sets at least one hour out of "7 hours or more" which is a condition for supplementary light between 17:00 and 24:00.

Further, it is preferable that the setting unit 22b sets the illuminance due to the supplementary light to 120 lpx or more as a condition for the supplementary light. As a condition of supplementary light, the setting unit 22b may set the illuminance to be 1.2 times or more the predetermined illuminance standard when the general illuminance of the living room is 100 lpx, or the supplementary light lighting time of 7 hours or more. preferable. The predetermined illuminance standard is, for example, the general illuminance of the living room of 100 lpx, but for example, it may be the general illuminance recommended by JIS Z 9110: 2011 general rules of lighting standards, etc. Not done. Further, the supplementary light lighting time is a time for lighting under the supplementary light condition, and indicates 7 hours or more. For example, the supplementary light lighting time means that the light is lit for 7 hours or more at an illuminance 1.2 times or more the predetermined illuminance standard. The setting unit 22b can communicate with the control unit 23 by wire or wirelessly. The setting unit 22b outputs the set supplementary light conditions to the control unit 23.

The control unit 23 controls the light emitted by the lighting device 30 based on the supplementary light conditions according to the user's condition. That is, when the control unit 23 acquires the supplementary light condition from the setting unit 22b, the control unit 23 controls the lighting device 30 by outputting an instruction according to the acquired supplementary light condition to the lighting device 30.

[Lighting device 30]
The lighting device 30 can illuminate the surroundings and is installed on a construction material such as a ceiling or a wall. The lighting device 30 is connected to the control system 20 by wire or wireless communication, and emits light according to an instruction output from the control unit 23 to illuminate the surroundings and expose the user to light as supplementary light. Further, the lighting device 30 can also illuminate the surroundings by normal lighting.

<Processing>
Next, the processing of the control system 20 and the lighting system 10 in the present embodiment will be described.

FIG. 3 is a flowchart showing the operation of the lighting system 10 in the first embodiment.

First, the first measurement unit 21a measures the user's body (S11). The first measurement unit 21a outputs the measured user information about the user's body to the determination unit 22a.

Next, the determination unit 22a acquires user information about the user's body measured by the measurement unit, and determines the user's state based on the acquired user information (S12). The determination unit 22a outputs the determined determination result to the setting unit 22b.

For example, when the user information is a heart rate, the determination unit 22a determines whether or not the acquired heart rate has increased by a predetermined amount in a predetermined period, or determines whether or not there is irregularity. When the heart rate increases by a predetermined amount within a predetermined period, or when there is irregularity within the predetermined period, the determination unit 22a determines that the user's state is a sleep deterioration state. Further, the determination unit 22a determines that the user's state is a good sleep state, such as when the heart rate does not increase by a predetermined amount within a predetermined period or when there is no irregularity.

The setting unit 22b sets the supplementary light condition according to the user's state based on the determination result determined by the determination unit 22a (S13). The setting unit 22b sets the lighting time of the supplementary light by the lighting device 30 to 7 hours or more in one day (or 24 hours) as a condition of the supplementary light. Further, the setting unit 22b sets the supplementary light condition so as to include at least one hour between 17:00 and 24:00 out of the set time of 7 hours or more. The setting unit 22b outputs the set supplementary light conditions to the control unit 23. The control unit 23 controls the lighting device 30 according to the supplementary light conditions acquired from the setting unit 22b. As a result, the lighting device 30 exposes the user to light as supplementary light. Then, the lighting system 10 ends the process.

<Experimental results>
FIG. 4A is a diagram showing the relationship between the dimming rate and the lighting time, and the color temperature and the lighting time. In FIG. 4A, the horizontal axis represents the time, the left vertical axis represents the dimming rate, and the right vertical axis represents the color temperature. Further, FIG. 4B is a diagram showing the sleep efficiency before supplementary light in the main sleep and the sleep efficiency in the main sleep after being exposed to the light by the supplementary light under the conditions of FIG. 4A.

In FIG. 4A, the dimming rate in the time zone from 6:00 to 14:00 is increased by 4 to 10 times as compared with the dimming rate in other time zones, and the color temperature is increased by 1.2 times as compared with the other time zones. I increased it more than twice. In this case, as shown in FIG. 4B, it was found that the sleep efficiency in the main sleep was higher after the supplementary light than before the supplementary light.

FIG. 4C is a diagram showing the relationship between the dimming rate and the lighting time, which are different from those in FIG. 4A, and the color temperature and the lighting time. In FIG. 4C, the horizontal axis represents the time, the left vertical axis represents the dimming rate, and the right vertical axis represents the color temperature. Further, FIG. 4D is a diagram showing the sleep efficiency before supplementary light in the main sleep and the sleep efficiency in the main sleep after being exposed to the light by the supplementary light under the conditions of FIG. 4C.

In FIG. 4C, in the time zone from 6:00 to 20:00, the dimming rate is increased by 4 to 10 times as compared with the other time zones, and the color temperature is increased by 1.2 times or more as compared with the other time zones. rice field. Even in this case, as shown in FIG. 4D, it was found that the sleep efficiency in the main sleep was higher after the supplementary light than before the supplementary light.

From these facts, as the condition of the supplementary light, the illuminance at the time of normal lighting is set to 1.2 times or more, and the lighting time of the supplementary light by the lighting device 30 is set to 7 hours or more in a day, preferably 10 hours. I decided to set it above. In addition, as a condition of supplementary light, it may be set to twice or more the illuminance at the time of normal lighting. Further, as a condition of supplementary light, the lighting time zone of supplementary light was set to include one hour or more in the time zone after 17:00. Further, as a condition of supplementary light, the illuminance by supplementary light is set to 120 lpx or more (for example, 1.2 times the general illuminance of 100 lpx in the living room) so that it becomes 840 lpx · h or more, which is the product of 7 hours and 120 lpx. I set it. As a condition for supplementary light, the illuminance due to supplementary light may be set to 650 lx or more, and may be set to be 4500 lx · h or more, which is the product of 7 hours and 650 lx.

<Effect>
Next, the operation and effect of the control system 20 in the present embodiment will be described.

As described above, the control system 20 in the present embodiment acquires the user information about the user's body measured by the measuring device 21, and based on the acquired user information, determines the user's state and the determination unit 22a. A setting unit 22b that sets supplementary light conditions according to the user's state based on the determination result determined by the determination unit 22a, and a control unit that controls the light emitted by the lighting device 30 based on the supplementary light conditions. 23 and. Then, the setting unit 22b sets the lighting time of the supplementary light to 7 hours or more as the light emitted by the lighting device 30 as a condition of the supplementary light.

By determining the user's condition in this way, it is possible to automatically set the supplementary light condition without inputting the supplementary light condition suitable for each user's condition. As a result, in the control system 20, in addition to the normal amount of light received by the user, the user can be exposed to light according to the supplementary light condition.

Therefore, the control system 20 can easily set the supplementary light conditions according to the user's condition and lifestyle. In this control system 20, the function of the user's biological rhythm can be maintained or improved even if the user who receives less than the amount of light received per day does not change his / her lifestyle.

Further, the lighting system 10 in the present embodiment includes a control system 20 and a lighting device 30 that illuminates the surroundings as supplementary light to the user by being controlled by the control system 20.

The lighting system 10 also has the same effect as described above.

Further, in the control system 20 according to the present embodiment, the setting unit 22b sets the illuminance as 1.2 times or more the illuminance with respect to the predetermined illuminance reference, or the illuminance lighting time of 7 hours or more as the condition of the supplementary light. do.

According to this, it is possible to further maintain or improve the user's biological rhythm function without changing the lifestyle of the user.

Further, in the control system 20 of the present embodiment, the setting unit 22b sets the lighting time zone of the supplementary light to include one hour or more of the time zone after 17:00 as a condition of the supplementary light.

According to this, since improvement of sleep efficiency can be expected as shown in FIGS. 4C and 4D, it is possible to more reliably maintain or improve the biological rhythm function of the user.

Further, in the control system 20 according to the present embodiment, the setting unit 22b sets the lighting time zone of the supplementary light to 10 hours or more.

(Modified Example of Embodiment 1)
The control system 20 of this modification will be described.

This modified example differs from the control system 20 of the first embodiment in that the light is supplemented for 7 hours or more after 10 o'clock in the morning.

Unless otherwise specified, the configuration of the control system 20 of this modification is the same as that of the first embodiment, and the same configuration is designated by the same reference numerals and detailed description of the configuration will be omitted.

In this modification, the setting unit 22b sets the lighting time of the supplementary light to 7 hours or more in the time zone after 10:00 in the morning. That is, the setting unit 22b sets the lighting time of the supplementary light to any 7 hours or more in the time zone from 10:00 to 19:00. Preferably, the setting unit 22b sets the lighting time of the supplementary light to any 7 hours or more in the time zone from 11:00 to 19:00.

FIG. 5A is a diagram showing the relationship between the dimming rate and the lighting time, and the color temperature and the lighting time. In FIG. 5A, the horizontal axis represents the time, the left vertical axis represents the dimming rate, and the right vertical axis represents the color temperature. Further, FIG. 5B is a diagram showing the sleep efficiency before supplementary light in the main sleep and the sleep efficiency in the main sleep after being exposed to the light by the supplementary light under the condition of FIG. 5A.

As shown in FIG. 5A, the color temperature is increased by about 1.2 times in the time zone from 5:30 to 19:00 as compared with other time zones, and in the time zone from 11:00 to 19:00, other times. The dimming rate was increased from 4 times to 10 times compared to the band. In this case, as shown in FIG. 5B, it was found that the sleep efficiency in the main sleep was higher after the supplementary light than before the supplementary light.

In such a control system 20 in this modification, the setting unit 22b sets the lighting time zone of the supplementary light to any 7 hours or more in the time zone from 10:00 to 19:00.

According to this, it is possible to expose a user who does not receive enough light per day to a large amount of light in the time zone around the evening. Therefore, the user is less likely to suffer from drowsiness in the evening and can sleep at night. Therefore, taking a nap in the evening can be expected to have an effect of improving the biological rhythm function for a user whose sleep state is not good at night.

This modified example also has the same effect as that of the first embodiment described above.

(Embodiment 2)
The control system 20 of the present embodiment will be described.

The present embodiment is different from the control system 20 of the first embodiment in that the control system 20 has a display unit 26 and the like.

FIG. 6 is a block diagram showing the lighting system 10 according to the second embodiment.

Unless otherwise specified, the configuration of the control system 20 of the present embodiment is the same as that of the first embodiment, and the same configuration is designated by the same reference numerals and detailed description of the configuration is omitted.

As shown in FIG. 6, the control system 20 includes a storage unit 25 and a display unit 26 in addition to the measuring device 121, the processing unit 22, and the control unit 23.

The measuring device 121 measures the user's daily sleep time. The measuring device 121 outputs the measured information indicating the daily sleep time of the user to the storage unit 25 via the determination unit 22a and the setting unit 22b.

The storage unit 25 is a semiconductor memory, a hard disk drive, or the like. The storage unit 25 periodically acquires and stores the information output by the measuring device 121 indicating the sleep time of the user.

The processing unit 22 reads out the information indicating the user's sleep time stored in the storage unit 25, and causes the display unit 26 to display the sleep-related information regarding the user's sleep based on the information indicating the sleep time. The sleep-related information is, for example, the user's sleep time, sleep efficiency, etc. in a predetermined period. The predetermined period is, for example, evening, night, and the like.

For example, the processing unit 22 calculates the sleep efficiency of the user based on the sleep time shown in the sleep-related information. Specifically, the processing unit 22 calculates the sleep efficiency of the latest one week or the latest two weeks as the latest predetermined period. More specifically, the processing unit 22 calculates the sleep efficiency in the evening and at night as a predetermined period. In the present embodiment, the processing unit 22 calculates the nighttime sleep efficiency as a predetermined period. The processing unit 22 outputs the calculated sleep efficiency and sleep time to the display unit 26.

The nighttime sleep efficiency may be calculated based on the main sleep, which has the longest sleep time in the nighttime zone, or may be the sleep time at a preset time, and the user's awakening time and getting out of bed may be calculated. It may be calculated based on time.

The display unit 26 is, for example, a monitor such as a liquid crystal panel or an organic EL panel. When the display unit 26 acquires the sleep-related information from the processing unit 22, the display unit 26 displays the acquired sleep-related information. For example, as shown in FIG. 7, as sleep-related information, the sleep efficiency of the last week and the sleep efficiency of the last two weeks at night, the sleep time of the main sleep of the last week in the evening, and the main sleep of the last two weeks. Display the sleep time of sleep. FIG. 7 is a schematic diagram showing sleep-related information displayed on the display unit 26 of the control system 20 according to the second embodiment.

As described above, in the control system 20 of the present embodiment, the setting unit 22b causes the display unit 26 to display sleep-related information regarding the user's sleep in the evening and at night.

According to this, as sleep-related information, for example, the user can recognize his / her own sleep time zone, so that he / she can recognize the state of sleep deterioration. By referring to sleep-related information in setting the conditions for supplementary light, it can be useful for maintaining or improving the biological rhythm function of the user.

The present embodiment also has the same effect as that of the above-described first embodiment.

(Modification 1 of Embodiment 2)
The control system 20 of this modification will be described.

As shown in FIG. 8, the present modification differs from the control system 20 of the second embodiment in that the display unit 26 displays at least one or more of sleep-related information, lighting-related information, and occupancy-related information. do. FIG. 8 is a schematic diagram showing sleep-related information, lighting-related information, and occupancy-related information displayed on the display unit 26 of the control system 20 in the modified example of the second embodiment.

Unless otherwise specified, the configuration of the control system 20 of this modification is the same as that of the second embodiment, and the same configuration is designated by the same reference numerals and detailed description of the configuration is omitted.

In this modification, the setting unit 22b causes the display unit 26 to display at least one or more of sleep-related information, lighting-related information, and occupancy-related information.

The lighting-related information is information regarding the lighting time of the lighting device 30. That is, the lighting-related information is information indicating the lighting time at a predetermined time (for example, daytime, evening, nighttime, etc.), the lighting condition set for supplementing the user, and the like.

The occupancy-related information is information regarding the existence of the user in the room where the lighting device 30 is arranged. That is, the occupancy-related information is information indicating the time or time zone in which the user is staying in the room, whether or not the user is staying in the room, and the like.

In such a control system 20 in this modification, the setting unit 22b has sleep-related information regarding the user's sleep, occupancy-related information regarding the presence of the user in the room where the lighting device 30 is arranged, and the lighting device 30. At least one or more of the lighting-related information regarding the lighting time is displayed on the display unit 26.

According to this, the user can recognize the sleep-related information, the occupancy-related information, and the lighting-related information displayed on the display unit 26 as his / her own state.

This modified example also has the same effect as that of the second embodiment described above.

(Modification 2 of Embodiment 2)
The control system 20 of this modification will be described.

This modification is different from the control system 20 of the second embodiment in that the display unit 26 displays the determination result as shown in FIG.

FIG. 9 is a schematic diagram showing a state of poor sleep and a state of good sleep on the display unit 26 of the control system 20 in the second modification of the second embodiment.

In this modification, as shown in FIG. 9, the determination unit 22a causes the display unit 26 to display the determination result. That is, the determination unit 22a outputs the determined state of the user to the display unit 26 via the setting unit 22b based on the user information. As a result, the display unit 26 displays the user's status. As a determination result, the display unit 26 shows, for example, the time zone between the sleep state one day before (indicated by hatching of diagonal lines) and the wakefulness state one day before (indicated by hatching of dots), the latest one week or the latest two weeks. Whether or not there is a state of good sleep and whether or not there is a state of worsening sleep.

The case of improvement from a state of poor sleep to a state of good sleep will be described with reference to FIG.

FIG. 10 is a diagram showing changes in the user's state when the control system 20 in the second modification of the second embodiment lights up at predetermined lighting periods under the condition of supplementary light. In FIG. 10, as a predetermined lighting period, the lighting period for performing supplementary light is set to 2 weeks, and as the next period, the lighting period for determining the state of the user is set to 1 week. In the present embodiment, the two weeks and the one week were repeated.

As shown in FIG. 10, since the user was in a state of sleep deterioration in the first two weeks, light was irradiated as a light irradiation condition according to the supplementary light condition for the sleep worsening person. In the next week, the state of the user was determined while irradiating light according to the supplementary light conditions for the sleep-impaired person. In FIG. 10, since the user was in a state of sleep deterioration as a determination result, the user was irradiated with light according to the supplementary light conditions for the sleep worsening person for another two weeks. Further, in the next week, the state of the user was determined while irradiating light according to the supplementary light condition for the sleep-impaired person. In FIG. 10, since the user improved from a state of poor sleep to a state of good sleep, in the next two weeks, normal light for a person with good sleep was irradiated as a light irradiation condition. Ordinary light is merely lighting by the lighting device 30, not light by supplementary light. In addition, in the next week, the state of the user was judged while irradiating normal light for a person with good sleep. Hereinafter, the same process is repeated. Even a person with good sleep may be irradiated with light as supplementary light.

In such a control system 20 in this modification, the determination unit 22a causes the display unit 26 to display the determination result.

According to this, the user can recognize his / her sleeping state. By referring to this information in setting the conditions for supplementary light, it can be useful for maintaining or improving the biological rhythm function of the user.

(Modification 3 of Embodiment 2)
The control system 20 of this modification will be described.

As shown in FIG. 11, this modified example differs from the control system 20 of the second embodiment in that the display unit 26 displays the period during which the light is supplemented.

FIG. 11 is a schematic diagram showing a state of poor sleep, a state of good sleep, and a lighting period of light on the display unit 26 of the control system 20 in the third modification of the second embodiment.

In this modification, the setting unit 22b causes the display unit 26 to display the period for performing the supplementary light included in the supplementary light condition. When the setting unit 22b sets the supplementary light condition, the setting unit 22b outputs the set supplementary light condition to the display unit 26. As a result, the display unit 26 displays the supplementary light conditions set by the setting unit 22b.

The display unit 26 displays the lighting period for performing supplementary light as a condition for supplementary light set by the setting unit 22b. The lighting period for supplementing the light is a preset period according to the conditions for supplementing the light. For example, if the user is in a state of poor sleep in the last week, the setting unit 22b sets the normal type, and the display unit 26 displays the normal type. In the normal type, the light is supplemented only during the first lighting period (for example, one week or two weeks).

Further, for example, when the storage unit 25 has a history of changes from a good sleep state to a poor sleep state in the last week, the setting unit 22b sets and displays an extended type in addition to the normal type. It is also displayed that the unit 26 is an extension type as a condition of supplementary light. The extended type means that the first lighting period is further extended by a predetermined period.

Further, the setting unit 22b does not have to set the supplementary light condition, for example, if the sleep is always good in the last two weeks. Further, even if the user who was in a state of poor sleep between the last 3 weeks and the last week before becomes a state of good sleep in the last week, the setting unit 22b is a normal type. You may set the condition of the supplementary light of. Further, if the user is in a state of sleep deterioration continuously in the last two weeks, the setting unit 22b sets the deterioration type in which the amount of light as supplementary light is increased as compared with the normal type as the condition of supplementary light. May be good. In the aggravated type, the light may be supplemented only for a second lighting period longer than the first lighting period.

A case where a user who has improved from a state of poor sleep to a state of good sleep transitions to a state of poor sleep again will be described with reference to FIG.

FIG. 12 is a diagram showing changes in the user's state when the control system 20 in the third modification of the second embodiment lights up at predetermined lighting periods according to the supplementary lighting conditions. In FIG. 12, as a predetermined lighting period, the lighting period (replenishment period) for performing supplementary light is set to 2 weeks, and then the lighting period (judgment period) for determining the user's state is set to 1 week. .. In the present embodiment, the supplementary lighting period and the determination period are repeatedly executed.

As shown in FIG. 12, since the user was in a state of sleep deterioration in the first two weeks, light was irradiated as a light irradiation condition according to the supplementary light condition for the sleep worsening person. In the next week, the state of the user was determined while irradiating light according to the supplementary light conditions for the sleep-impaired person. In FIG. 12, as a result of the determination, the user was improved from a state of poor sleep to a state of good sleep. Therefore, in the next two weeks, normal light was irradiated as a light irradiation condition for a person with good sleep. In addition, in the next week, the state of the user was judged while irradiating normal light for a person with good sleep. As a result of the determination, since the user has returned from a good sleep state to a poor sleep state, the lighting period for emitting light according to the supplementary light condition is extended for the sleep worsened person. Persons with poor sleep who have been extended are eligible for extension. In FIG. 12, the next lighting period was extended from 2 weeks to 6 weeks, and in these 6 weeks, the sleep-deteriorated person was irradiated with light according to the supplementary light condition for the sleep-deteriorated person as the light irradiation condition. Hereinafter, the same process is repeated.

<Processing>
Next, the processing of the control system 20 in this modification will be described.

FIG. 13 is a flowchart showing the operation of the control system 20 in the third modification of the second embodiment.

As shown in FIG. 13, the first measurement unit 21a measures the user's body (S11), and the determination unit 22a determines the user's state based on the user information regarding the user's body (S12).

The determination unit 22a determines whether or not the user's state is a state of poor sleep (S31).

When the user's state is a sleep deterioration state (YES in S31), the setting unit 22b determines whether or not the storage unit 25 has a history of changing from a sleep good state to a sleep deterioration state within a specified period. Judgment (S32). The specified period referred to here is a period in which the setting can be arbitrarily changed, and is, for example, several weeks to several months.

When there is a history of change from a good sleep state to a poor sleep state (YES in S32), the setting unit 22b adds an extended type to the supplementary light condition (S33).

If the user's state is not a state of poor sleep (NO in S31), the determination unit 22a ends the process. Further, the setting unit 22b also ends the process even when there is no history of change from the state of good sleep to the state of poor sleep (NO in S32).

In such a control system 20 in this modification, the setting unit 22b causes the display unit 26 to display the period for performing the supplementary light included in the supplementary light condition.

As a result, for example, when the amount of light received by the user decreases due to changes in the supplementary light conditions, the amount of light received per day is insufficient for the user who has changed from a good sleep state to a poor sleep state. You can recognize that. Therefore, when the user receives the supplementary light again, it can be useful for maintaining or improving the biological rhythm function of the user.

(Modification 4 of Embodiment 2)
The control system 20 of this modification will be described.

As shown in FIG. 14, this modified example differs from the control system 20 of the second embodiment in that the measuring device 121 measures at least one of the user's room time and lighting time.

FIG. 14 is a schematic view showing lighting-related information, occupancy-related information, and a person who is applicable to use, which is displayed on the display unit 26 of the lighting system 10 in the fourth modification of the second embodiment.

In this modification, the measuring device 121 measures at least one of the time the user is in the room where the lighting device 30 is arranged and the lighting time when the lighting device 30 is lit.

The measuring device 121 has a second measuring unit 21b in addition to the first measuring unit 21a.

The second measurement unit 21b measures at least one of the time the user is in the room where the lighting device 30 is arranged and the lighting time when the lighting device 30 is lit. In the present embodiment, the second measuring unit 21b measures the occupancy time and the lighting time. The second measuring unit 21b has at least one of a time measuring unit such as a motion sensor and a timer sensor. The second measurement unit 21b can communicate with the determination unit 22a by wire or wirelessly.

For example, the motion sensor detects the presence or absence of the user in the room where the lighting device 30 is arranged. In addition, the motion sensor measures the staying time of the user existing in the room. The motion sensor has a time measuring unit such as a timer. When the motion sensor measures the occupancy time of the user existing in the room, the motion sensor outputs information indicating the occupancy time, which is the result of the measurement, to the determination unit 22a.

In addition, the timer sensor detects whether or not the lighting device 30 arranged in the room is lit. The timer sensor also measures the lighting time of the lighting device 30. When the timer sensor measures the lighting time of the lighting device 30 in the room, the timer sensor outputs information indicating the lighting time, which is the measurement result, to the determination unit 22a.

The determination unit 22a outputs the user information of the user who is the target of the set supplementary light condition to the display unit 26, so that the display unit 26 displays the user information. The user information further includes information indicating whether the user is a applicable person or a non-applicable person, and information indicating the age of the user. The relevant person indicates a user who has been in the room for a predetermined time or longer. The non-applicable person indicates a user who has been in the room for less than a predetermined time. If the user is a person concerned, the lighting device 30 can be expected to maintain or improve the biological rhythm function of the user by lighting according to the supplementary light condition. However, if the user is a non-applicable person, even if the lighting device 30 normally lights up, the lighting device 30 does not light up according to the supplementary light condition, so that the user's biological rhythm function cannot be expected to be maintained or improved.

The determination unit 22a may display at least one of the user information, the measured occupancy time, and the lighting time on the display unit 26, and display all of them on the display unit 26 as in the present embodiment. It does not have to be.

FIG. 15 is a schematic diagram showing physical information, mental information, and behavioral information displayed on the display unit 26 of the lighting system 10 in the modified example 4 of the second embodiment.

In FIG. 15, the determination unit 22a causes the display unit 26 to display information on the user's heart rate as physical information. For example, the determination unit 22a determines whether or not there is an increase of the threshold value or more based on the degree of change in the heart rate of the user in the most recent week. As a result of the determination, the determination unit 22a displays an increase / decrease in the heart rate (an example of information on the heart rate) in the last week. Further, for example, the determination unit 22a determines whether or not there is irregularity based on the degree of change in the heart rate of the user in the most recent week. As a result of the determination, the determination unit 22a displays the presence or absence of irregularity in the heart rate for the last week (an example of information on the heart rate). Heart rate irregularity is indicated by the difference between the maximum and minimum values per unit time.

Further, the determination unit 22a causes the display unit 26 to display the degree of depression of the user as mental information. The determination unit 22a appropriately determines the degree of depression of the user based on, for example, the depression scale.

Further, the determination unit 22a causes the display unit 26 to display the presence / absence of medication and the amount of activity of the user as action information. For example, the determination unit 22a determines whether or not the number of types of medicines to be taken by the user is equal to or greater than the threshold value, and displays the determination result on the display unit 26. Further, the determination unit 22a determines whether or not there is a decrease of the user's activity amount by the threshold value or more based on the activity amount in the most recent week, and displays the determination result on the display unit 26.

Such a control system 20 in this modification includes a measuring device 121 that outputs user information about the user's body by measuring the user's body. Further, the measuring device 121 measures at least one of the time when the user is present in the room where the lighting device 30 is arranged and the lighting time when the lighting device 30 is lit. Then, the determination unit 22a causes the display unit 26 to display at least one of the user information subject to the set supplementary light condition, the measured occupancy time, and the lighting time.

As a result, it can be recognized that the relevant person can be expected to maintain or improve the biological rhythm function of the user depending on the conditions of supplementary light. In addition, it can be recognized that the non-applicable person cannot be expected to maintain or improve the biological rhythm function of the user due to the supplementary light condition. In this case, a means other than the supplementary light can be used as a guide as to whether or not the non-applicable user needs a means other than the supplementary light.

In such a control system 20 in this modification, the user information includes the age of the user.

According to this, considering that the sleep time changes according to the age and the sleep time tends to decrease with aging, the sleep efficiency of the user can be accurately determined.

In such a control system 20 in this modification, the determination unit 22a uses at least one of physical information indicating the user's body, mental information indicating the user's spirit, and behavior information indicating the user's behavior as user information. The above information is displayed on the display unit 26.
