First, the configuration of the rest room 1 of the present embodiment will be described.

Fig. 1 is a perspective view showing an external appearance of a rest room 1 according to the embodiment.

As shown in fig. 1, the resting room 1 is formed with an indoor space R accommodating a bed 30 for a user to sleep or rest. The user can reduce drowsiness or eliminate fatigue by making a nap, sleep or rest in the indoor space R. That is, in the resting room 1, the user can nap or sleep, or the user can take a rest. Here, in the present embodiment, the nap is a sleep for a short time, specifically, a sleep for a short time with a use time of less than 30 minutes. Here, in the present embodiment, sleep refers to sleep for a long period of time, which is 30 minutes or longer. Here, the use time is a period of use of the restroom desired by the user, and is a period from the time when the instruction to start use of the restroom is input to the input unit 91 to the time when the control of the lighting system 3 is finished.

In addition, the reason why less than 30 minutes is defined as nap and 30 minutes or more is defined as sleep is that the sleep is more effective in terms of "psychophysiology \1239225 (1): 45-59, 2007 collected sleep science 12408, lying in later noon, lying towards 1239275, lying in a short school of the university of islands: 322076, respectively, the science research academy of the groba university forest, 10, horiba loyalty, etc. (physiology and psychology 25 (1): 45-59, 2007 collected the contribution of psychology to sleep as a measure for afternoon sleepiness, disclosing that the people in short time of less than 30 minutes wondered comfortably, and the sleepiness in more than 30 minutes became deeper sleep for the slow wave sleep.

Further, the rest room 1 can illuminate the indoor space R. For example, when the user uses the device as a sleeping room, when the use time is set, the device performs lighting for making the user fall asleep, lighting for waking up (waking up) the user in a sleeping state, and the like. In addition, when the user uses the room as the rest room 1, the interior space R can be illuminated.

In the present embodiment, the suction port 20b is disposed to face the blower 62 so as to communicate the outside space with the 3 rd space R3.

[ Lighting System 3]

As shown in fig. 1 and 2, when the user inputs the use time via the input unit 91, the lighting system 3 illuminates the surface of the bed 30 where the user is sleeping, and performs a lighting mode for making the user fall asleep at the start of the use time, a lighting mode for making the user fall asleep, a lighting mode for making the user wake up at the end of the use time, and the like. That is, the lighting system 3 executes each lighting mode, thereby providing an environment for supporting the user to fall asleep and for the user who has fallen asleep to wake up.

Specifically, the lighting system 3 includes the bed 30, the operation device 40, the control device 60, the lighting fixture 71, the light shielding portion 11f3, the input portion 91, the arithmetic portion 92, the sound device 61, the blower 62, the fragrance unit 63, and the power supply portion 80. The lighting system 3 may be provided with at least 1 of the sound device 61, the blower 62, and the fragrance unit 63, instead of all of them.

The bed 30 can be used for seating and sleeping. Further, the bed 30 is elongated in the X-axis direction in the 1 st space R1. The bed 30 of the present embodiment is supported by the plurality of columns 11c, but may be placed on the base 11a and the plurality of joists 11a1.

The bed 30 is set such that the head of the user is positioned on the positive X-axis side of the bed 30 and the feet are positioned on the negative X-axis side of the bed 30.

The bed 30 of the present embodiment functions as a bed by deforming the chair. Specifically, the bed 30 may include a seat portion on which the user sits, a footrest portion rotatably coupled to the seat portion, a backrest portion rotatably coupled to the seat portion, and a headrest coupled to the backrest portion. In this case, the chair may function as a bed in which the leg rest portion, the seat portion, the backrest portion, and the headrest are arranged in a linear array. The bed 30 of the present embodiment may be inclined or may be deformed like a chair. In the case of a chair, the illuminance on the surface of the backrest portion and the illuminance on the surface of the headrest when the user leans against the backrest portion and puts the head on the headrest correspond to the illuminance on the floor surface.

The operation device 40 is disposed on the positive X-axis direction side of the bed 30 in the 1 st space R1. That is, when the user is sleeping on the bed 30, the operation device 40 is disposed near the head. The operation device 40 may be disposed in 1 or more of the 1 st space R1, the 2 nd space R2, and the 3 rd space R3. That is, a plurality of the operating devices 40 may be provided in the rest room 1.

The operating device 40 can be operated by the user independently of the acoustic device 61, the blower 62, and the fragrance unit 63. That is, the operation device 40 outputs an instruction of the user operation to the control device 60, and the operation device 60 drives or stops the sound device 61, the blower 62, and the fragrance unit 63, respectively. The operating device 40 may be configured to be able to operate only at least 1 of the sound device 61, the blower 62, and the fragrance unit 63. The operating device 40 can also operate the lighting fixture 71.

The control device 60 can control the sound device 61, the blower 62, and the fragrance unit 63, respectively, in accordance with instructions from the operation device 40. The control device 60 may control only at least 1 of the sound device 61, the blower 62, and the fragrance unit 63. The control device 60 can also control the lighting fixture 71.

Here, the control of the sound device 61, the blower 62, and the fragrance unit 63 by the control device 60 will be described.

For example, when the user operates operation device 40 to input an instruction, control device 60 instructs sound device 61 to play music in accordance with the instruction acquired from operation device 40. Thereby, the music is played by the acoustic device 61, and the played music is output into the indoor space R. Further, the control device 60 can change the music played by the acoustic device 61 or control the volume of the music output by the acoustic device 61 by receiving an instruction from the operation device 40.

When the user operates the operation device 40 and inputs an instruction to turn the blower 62 from the off state to the on state, the control device 60 turns on the power of the blower 62 in accordance with the instruction obtained from the operation device 40. Thereby, the blower 62 is driven, and the air in the external space is taken into the indoor space R of the room 10. The control device 60 can control the output of the blower 62, that is, the rotation speed of the fan of the blower 62 by receiving an instruction from the operation device 40.

When the user operates the operation device 40 to input an instruction to turn the fragrance unit 63 from the off state to the on state, the control device 60 turns on the power of the fragrance unit 63 in accordance with the instruction received from the operation device 40. As a result, the fragrance dispenser 63 is driven, and the fragrance of the fragrance dispenser 63 is introduced into the air in the indoor space R. Further, the control device 60 can control the output of the fragrance dispenser 63, that is, the amount of the aromatic agent introduced into the indoor space R by receiving an instruction from the operation device 40.

The lighting fixture 71 can illuminate the indoor space R. The lighting fixture 71 has a light control function of changing the amount of light. Therefore, the lighting fixture 71 can change the light output by receiving the lighting control instruction from the arithmetic unit 92. For example, the lighting fixture 71 obtains a lighting control instruction corresponding to the usage time from the arithmetic unit 92, and executes the dimming control. This enables the lighting fixture 71 to change the brightness (brightness) during the use time.

The lighting fixture 71 may perform dimming and color adjustment in response to a direct instruction from the operation device 40.

The lighting fixture 71 is provided on the foot side of the user when sleeping on the bed 30. Specifically, the lighting fixture 71 is disposed in the 3 rd space R3. In addition, a plurality of lighting fixtures 71 may be provided in the 3 rd space R3. The lighting device 71 may be embedded in the light shielding portion 11f3.

In addition, a plurality of lighting fixtures 71 may be provided. Specifically, the lighting fixture 71 may be further provided on the top plate 13. In this case, the lighting fixture 71 is disposed vertically above the upper body when the user is sleeping on the bed 30. The lighting fixture 71 may be disposed such that the distance between the lighting fixture 71 and the head region R1a, which is the region where the head of the user is disposed when the user is sleeping on the bed 30, is 1.5m or less.

As shown in fig. 1 and 3, the light shielding portion 11f3 is disposed between the lighting fixture 71 and the head region R1 a. Specifically, the light shielding portion 11f3 is disposed on the foot side of the user when sleeping on the bed 30 and at the boundary between the 1 st space R1 and the 3 rd space R3. Therefore, the light blocking portion 11f3 is substantially parallel to the YZ plane, and can block light emitted from the lighting fixture 71 so that the light does not directly irradiate the head of the user when the user is sleeping on the bed 30. The light shielding portion 11f3 may be an example of the wall portion 11f.

The light shielding portion 11f3 is disposed to face the second wall portion 11f2 with the lighting fixture 71 interposed therebetween. Therefore, the light shielding portion 11f3 forms an opening 11h through which light irradiated by the lighting fixture 71 passes, together with the 2 nd wall portion 11f 2. Thus, when the lighting fixture 71 is turned on, the light emitted from the lighting fixture 71 is reflected by the light shielding portion 11f3 and the second wall portion 11f2, is emitted from the opening 11h, is further reflected by the wall portion 11f of the room 10, the bed 30, and the like, and is irradiated to the head region R1 a.

The input unit 91 can receive an input from a user. Specifically, when the user inputs the use time to the input unit 91, the input unit 91 outputs the use time information, which is information indicating the use time input by the user, to the calculation unit 92.

The input unit 91 is disposed on the opposite side of the bed 30 in the longitudinal direction from the side on which the lighting fixture 71 is disposed. That is, the input unit 91 is disposed on the head side of the user when sleeping on the bed 30. Therefore, the user can lie on the operation input portion 91.

The input unit 91 may be integrally formed with the operation device 40. The input unit 91 may be configured separately from the operation device 40.

The use time includes an illumination fixed interval, a1 st illumination control interval, and a 2 nd illumination control interval. The 1 st illumination control section, the illumination fixed section, and the 2 nd illumination control section are arranged in this time-series order.

The illumination fixed section is a section in which the light output of the illumination fixture 71 is substantially fixed, and is a section in which the user falls asleep. The length of the illumination fixed interval is 20% or more of the length of the use time. In addition, the maximum value of the illuminance of the surface of the bed 30 in the illumination fixed interval, that is, the bed surface illuminance, is always less than 50lx. In addition, the maximum value of the bed surface illumination intensity can be less than 40lx, less than 30lx, less than 20lx and less than 10lx in total.

Here, the light output is substantially constant, and means, for example, that the brightness does not change for about 60 seconds on the bed surface or that the brightness does not change to the extent that the user does not feel the change in brightness. The change in brightness is, for example, within ± 10lx in 60 seconds. If the brightness changes to this degree, the user is less likely to be disturbed from sleeping.

Here, the bed surface illuminance is the illuminance of the surface of the bed 30 when at least one of the lighting fixtures 71 is lit. In particular, the maximum value of the floor illuminance of less than 50lx is the floor illuminance in the head region R1 a. The bed surface illuminance in the head region R1a is the illuminance of the surface of the bed 30 on which the head is disposed when the user is sleeping on the bed 30. In the present embodiment, the illuminance on the bed surface in the head region R1a is assumed to be the same as the illuminance on the face, which is the illuminance on the head of the user who is sleeping on the bed 30.

The 1 st illumination control section is a section before the illumination fixed section and is a section for prompting the user to fall asleep. The 1 st illumination control section includes a section in which the bed surface illuminance, which is the illuminance on the surface of the bed 30, is increased by 0.03lx or more for 5 seconds and a section in which the bed surface illuminance is decreased by 0.03lx or more for 5 seconds. That is, the fluctuation (fluctuation) of light such as the brightness or the dimming of the indoor space is periodically repeated in the 1 st illumination control section.

The average illuminance in the 1 st illumination control section is 1.5 times or more the average illuminance in the illumination fixed section. That is, since the section (illumination constant section) in which the user sleeps is darker than the section (1 st illumination control section) in which the user is encouraged to sleep, the rest room 1 is a suitable sleeping environment for the user.

The 2 nd illumination control interval is an interval behind the illumination fixed interval and is an interval for prompting the user to wake up. The 2 nd illumination control interval includes an interval in which the bed surface illuminance is increased by 10lx or more for 10 seconds. The length of the 2 nd lighting control section is 35% or less of the length of the use time.

The end point of the 2 nd illumination control interval substantially coincides with the end point of the usage time. That is, by arranging the 2 nd illumination control interval for waking up the user in the latter half of the usage time, the user can obtain an efficient rest.

The sum of the length of the 1 st illumination control section and the length of the illumination fixed section is longer than the length of the 2 nd illumination control section. In this case, the 1 st illumination control section as the section for prompting the user to fall asleep and the illumination fixed section as the section for the user to fall asleep can ensure a long fall asleep time of the user. Therefore, the user can take a nap time as long as possible even when the nap time is short, and can take a rest.

The length of the illumination fixed section is longer than that of the 1 st illumination control section. Since the illumination fixed interval is a period during which the user falls asleep, the arithmetic unit 92 sets the illumination fixed interval to be longer than the 1 st illumination control interval. This allows the user to take a nap for as long as possible even when the user has a short period of use, and thus can take a rest.

The calculation unit 92 acquires the use time information from the input unit 91, generates an illumination control instruction based on the acquired use time information, and outputs the generated illumination control instruction to the illumination fixture 71. Specifically, the calculation unit 92 changes the length of the illumination fixed section in accordance with the length of the use time indicated by the acquired use time information, and outputs an illumination control instruction corresponding to the changed illumination fixed section to the illumination fixture 71, thereby controlling the illumination fixture 71.

The arithmetic unit 92 outputs a lighting control instruction corresponding to the 1 st lighting control section to the lighting fixture 71, and controls the lighting fixture 71. Specifically, the calculation unit 92 changes the length of the 1 st illumination control section in accordance with the length of the use time indicated by the obtained use time information, and outputs an illumination control instruction corresponding to the changed length of the 1 st illumination control section to the illumination fixture 71, thereby controlling the illumination fixture 71.

The arithmetic unit 92 outputs an illumination control instruction corresponding to the 2 nd illumination control section to the illumination fixture 71, thereby controlling the illumination fixture 71. Specifically, the calculation unit 92 changes the length of the 2 nd illumination control section in accordance with the length of the use time indicated by the obtained use time information, and outputs an illumination control instruction corresponding to the changed length of the 2 nd illumination control section to the illumination fixture 71, thereby controlling the illumination fixture 71.

When the usage time is less than 30 minutes, the arithmetic unit 92 changes the length of the 1 st illumination control section so that the 1 st illumination control section is less than 5 minutes, and changes the length of the 2 nd illumination control section so that the 2 nd illumination control section is less than 5 minutes. The calculation unit 92 outputs the illumination control instruction corresponding to the changed length of the 1 st illumination control section and the changed length of the 2 nd illumination control section to the illumination fixture 71, thereby controlling the illumination fixture 71.

When the usage time is 30 minutes or longer, the arithmetic unit 92 changes the length of the 1 st illumination control section so that the 1 st illumination control section is 5 minutes or longer, and changes the length of the 2 nd illumination control section so that the 2 nd illumination control section is 5 minutes or longer. The calculation unit 92 outputs the illumination control instruction corresponding to the changed length of the 1 st illumination control section and the changed length of the 2 nd illumination control section to the illumination fixture 71, thereby controlling the illumination fixture 71.

The calculation unit 92 may change the length of the 1 st illumination control interval so that the 1 st illumination control interval is less than 5 minutes when the usage time is less than 30 minutes, and change the length of the 1 st illumination control interval so that the 1 st illumination control interval is 5 minutes or more when the usage time is 30 minutes or more. In this case, the change of the 1 st illumination control section when the 1 st illumination control section is less than 5 minutes and the change of the 1 st illumination control section when the 1 st illumination control section is 5 minutes or more may be a change in which the arithmetic unit 92 temporally expands and contracts the 1 st illumination control section in the time axis direction according to the length of the usage time. In this way, when the usage time is less than 30 minutes or the usage time is 30 minutes or more, the arithmetic unit 92 can set the 1 st illumination control section to be thin by temporally extending or contracting the 1 st illumination control section, so that there is continuity in the change of the brightness and a rapid change of the brightness is suppressed. This can suppress the user from feeling uncomfortable when waking up.

The calculation unit 92 may change the length of the 2 nd illumination control section so that the 2 nd illumination control section is smaller than 5 minutes when the usage time is shorter than 30 minutes, and change the length of the 2 nd illumination control section so that the 2 nd illumination control section is 5 minutes or longer when the usage time is 30 minutes or longer. In this case, the change of the 2 nd illumination control section when the 2 nd illumination control section is less than 5 minutes and the change of the 2 nd illumination control section when the 2 nd illumination control section is 5 minutes or more may be changes in which the 2 nd illumination control section is mutually expanded and contracted in time in the time axis direction. In this way, when the usage time is less than 30 minutes or the usage time is 30 minutes or more, the arithmetic unit 92 extends and contracts the 2 nd illumination control section in time, thereby providing continuity in the change of the brightness and suppressing a sudden change in the brightness. This can suppress the user from feeling uncomfortable when waking up.

Further, the change of the 2 nd illumination control interval when the 2 nd illumination control interval is less than 5 minutes may not have a relationship such as temporal expansion and contraction or similarity with the change of the 2 nd illumination control interval when the 2 nd illumination control interval is 5 minutes or more. In this way, in the 2 nd illumination control interval, different illumination controls may be performed when the 2 nd illumination control interval is less than 5 minutes and when it is 5 minutes or more. Since the way of going to nap varies depending on the user, the user can be prevented from feeling uncomfortable when waking up by changing the method of waking up the user.

The calculation unit 92 may set the driving of the lighting fixture 71 in any one of the 1 st lighting control interval and the 2 nd lighting control interval to the off state. For example, when the use time is too short, the user may be assured of a nap time by omitting one of the 1 st lighting control section and the 2 nd lighting control section.

By playing music to room 10, sound device 61 can provide the user with music having a sleep-in effect or with music having a wake-up effect. Sound device 61 is housed in room 10, and is disposed in indoor space R, for example. Sound device 61 can change the music played in indoor space R or adjust the volume by operating operation device 40 by the user.

The blower 62 is disposed in the room 10, sucks air from the suction port 20b provided in the room 10, and blows air from the discharge port 20a provided in the indoor space R, thereby generating an airflow in the indoor space R. The blower 62 is driven to take in air in the external space, and thereby the temperature, humidity, and the like of the air in the indoor space R can be adjusted.

Accordingly, the blower 62 is driven in a state of being disposed on the side of the suction port 20b of the duct 20, and can generate an airflow from the suction port 20b toward the discharge port 20a. Further, since the air blower 62 can blow air from the air outlet 20a, the air blown to the user who is sleeping on the bed 30 can be intensified or not blown. The output of such a blower 62 can be adjusted by the operation device 40.

The blower 62 is disposed on the foot side of the user when sleeping on the bed 30. The blower 62 is disposed in the flow path of the duct 20. In the present embodiment, the blower 62 is located at the same height as the suction port 20b so as to face the suction port 20b in the 3 rd space R3, and is disposed on the top plate 13 side of the bed 30 so as to be distant from the head of the user.

The fragrance unit 63 is disposed in the room 10, and can adjust the amount of the fragrance in the indoor space R by introducing the fragrance into the air blown out from the air outlet 20a. For example, the air blower 62 is driven under the control of the control device 60, and the fragrance applicator 63 causes the air flowing from the suction port 20b toward the discharge port 20a to contain the fragrance. That is, the aromatic agent is guided to the indoor space R by riding on the airflow from the suction port 20b toward the discharge port 20a. This enables the indoor space R to be filled with the fragrance preferred by the user. The output of such a fragrance means 63 can be regulated by the operating means 40.

In addition, the fragrance unit 63 can introduce the fragrance into the indoor space R without driving the blower 62. That is, the fragrance dispenser 63 can fill the indoor space R with fragrance of the aromatic agent only by being disposed in the indoor space R.

The fragrance unit 63 is disposed on the foot side of the user when the user is sleeping on the bed 30. Specifically, the fragrance unit 63 is disposed in the flow path of the duct 20 or the 3 rd space R3. In the present embodiment, the fragrance unit 63 is disposed on the top plate 13 side of the air blower 62 on the downstream side (the air outlet 20a side) of the air blower 62 and away from the head of the user.

In the present embodiment, the blower 62 and the fragrance applicator 63 are located on the Z-axis negative side (lower side) of the top plate 13, but the present invention is not limited to this. Only the blower 62 may be positioned on the Z-axis negative side with respect to the top plate 13. In the present embodiment, the blower 62 and the fragrance unit 63 are disposed on the foot side of the user when the user is sleeping on the bed 30, but the present invention is not limited thereto. Only the blower 62 may be disposed on the foot side of the user when sleeping on the bed 30. In these cases, the fragrance applicator 63 may be disposed on the top plate 13 or may be disposed near the outlet 20a of the duct 20.

The power supply unit 80 controls the output of light by supplying power to the lighting apparatus 71, or controls the output by supplying power to the sound device 61, the blower 62, and the fragrance unit 63. That is, the power supply unit 80 generates drive power for driving the lighting fixture 71, the sound device 61, the blower 62, and the fragrance unit 63, and supplies the drive power to the lighting fixture 71, the sound device 61, the blower 62, and the fragrance unit 63, respectively.

[ regarding 1 st illumination control interval ]

The lighting fixture 71 may perform lighting control at a constant cycle in the 1 st lighting control interval. That is, the lighting fixture 71 may alternately repeat the magnitude of the light output in a pulsating manner in the 1 st lighting control section by acquiring the lighting control instruction from the arithmetic unit 92. In this case, the light fluctuation is periodically repeated on the bed surface in the 1 st illumination control section so that the indoor space becomes bright or dark. The length of the 1 st illumination control section may be set to be substantially an integer multiple of a constant period.

Here, the brightness in the case where the illumination control is performed at a constant cycle in the 1 st illumination control section is described as an example in fig. 4A to 4E. Fig. 4A to 4E illustrate the bed illuminance, for example.

First, fig. 4A shows a case where the light fluctuation is periodically repeated when the 1 st illumination control interval is less than 5 minutes. As shown in fig. 4A, when the 1 st illumination control interval is short such as less than 5 minutes, the illumination device 71 may illuminate the bed surface so as to repeatedly turn on or off. Fig. 4A shows the light fluctuation of 5 cycles of 40 seconds per 1 cycle.

Next, fig. 4B is a diagram showing a case where the light fluctuation is periodically repeated when the 1 st illumination control interval is 5 minutes or more. As shown in fig. 4B, when the 1 st illumination control interval is long such as 5 minutes or longer, the illumination device 71 may illuminate the bed surface so as to repeatedly turn on or off. The variation of 23 periods of light for 40 seconds per 1 period is illustrated in fig. 4B.

Next, fig. 4C is another diagram showing a case where the light fluctuation is periodically repeated when the 1 st illumination control interval is less than 5 minutes. As shown in fig. 4C, when the 1 st illumination control section is short such as less than 5 minutes, the illumination apparatus 71 may illuminate the bed surface repeatedly in bright or dark states and the light fluctuation range may gradually decrease with the passage of time. The variation of light for 5 periods of 40 seconds per 1 period is illustrated in fig. 4C.

Next, fig. 4D is another diagram showing a case where the light fluctuation is periodically repeated when the 1 st illumination control interval is 5 minutes or more. As shown in fig. 4D, when the 1 st illumination control section is long as 5 minutes or longer, the illumination device 71 may illuminate the bed surface repeatedly to be bright or dark, and the light fluctuation range may gradually decrease with the passage of time. The variation of 23 periods of light for 40 seconds per 1 period is illustrated in fig. 4D.

When the user stays in a dark place such as the rest room 1 as shown in fig. 4C and 4D, the user does not feel that the fluctuation is too bright and the user is less likely to get in the sleep even in so-called dark adaptation in which the sensitivity of the eyes to the brightness increases.

Next, fig. 4E is another diagram showing a case where the light fluctuation is periodically repeated when the 1 st illumination control interval is 5 minutes or more. As shown in fig. 4E, when the 1 st illumination control interval is long such as 5 minutes or longer, the illumination device 71 may illuminate the bed surface so as to repeatedly turn on or off. As shown in fig. 4E, the time per 1 cycle may be longer than those in fig. 4A to 4D. Although not shown, the time per 1 cycle may be shorter than that in fig. 4A to 4D. The variation of light for 5 periods of 180 seconds per 1 period is illustrated in fig. 4E.

Fig. 4A to 4E show examples of the 1 st illumination control section, and the 1 st illumination control section is not limited to fig. 4A to 4E. The time and the number of cycles per 1 cycle are not limited to those in the present embodiment.

[ regarding the 2 nd illumination control section ]

Here, the illuminance of the floor surface in the 2 nd illumination control section is exemplified by fig. 5A to 5F.

The 2 nd illumination control section in fig. 5A to 5C, 5E, and 5F is illustrated as being longer than the 2 nd illumination control section in fig. 5D, and fig. 5D illustrates the 2 nd illumination control section as being shorter. The illumination control in fig. 5A to 5F is merely an example, and the illumination system 3 is not limited to the one described in fig. 5A to 5F.

First, fig. 5A is a view showing the illuminance on the floor surface in the 2 nd illumination control zone when the 2 nd illumination control zone is long. As shown in fig. 5A, when the 2 nd illumination control section is long, the illumination fixture 71 illuminates so as to increase the illuminance of the bed surface with the passage of time.

Next, fig. 5B is another diagram showing the floor surface illuminance of the 2 nd illumination control section in the case where the length of the 2 nd illumination control section is medium. As shown in fig. 5B, when the length of the 2 nd illumination control section is medium, the illumination fixture 71 performs illumination such that the bed surface illuminance rises with time at a steeper gradient (inclination) than that in fig. 5A.

Next, fig. 5C is another graph showing the floor surface illuminance in the 2 nd illumination control section in the case where the 2 nd illumination control section is short. As shown in fig. 5C, when the 2 nd illumination control section is short, the illumination fixture 71 increases the bed surface illuminance with a steeper gradient than that in fig. 5B as time elapses.

Next, fig. 5D is another graph showing the illuminance on the floor surface in the 2 nd illumination control zone in the case where the 2 nd illumination control zone is very short. As shown in fig. 5D, when the 2 nd illumination control section is very short, the illumination fixture 71 illuminates the floor surface so that the illuminance on the floor surface rises with time at a steeper gradient than that in fig. 5C.

Next, fig. 5E is another diagram showing the floor surface illuminance of the 2 nd illumination control section in the case where the length of the 2 nd illumination control section is medium. As shown in fig. 5E, the 2 nd illumination control section may have a 2 nd-1 st section in which the floor surface illuminance is raised very gradually, and a 2 nd-2 nd section in which the floor surface illuminance is raised at a steeper gradient than the 2 nd-1 st section. In this case, the illumination device 71 illuminates, but in the 2 nd-1 th section, the floor surface illuminance is very low, that is, the floor surface is dark. In the 2 nd-2 nd section, the bed surface illuminance rises rapidly and becomes bright.

Next, fig. 5F is another view showing the illuminance on the floor surface in the 2 nd illumination control zone when the 2 nd illumination control zone is long. As shown in fig. 5F, the 2 nd illumination control section may include a 2 nd-1 st section in which the floor surface illuminance is gradually increased and a 2 nd-2 nd section in which the floor surface illuminance is increased more rapidly than in the 2 nd-1 st section. In this case, in the 2 nd-1 st interval, the illumination of the bed surface is low, i.e., the bed surface is dim. In the 2 nd-2 nd section, the bed surface illuminance rises rapidly and becomes brighter.

In fig. 5A to 5D, when the user has a short nap time, the user may want to ensure the nap time as long as possible. In this case, the user may set the illumination control period as shown in fig. 5A, or may select illumination control with a short illumination control period as shown in fig. 5B, 5C, or the like. In this way, the user can select the lighting control having the lighting control period shorter than that of fig. 5A according to his or her preference by operating the operation device 40.

In fig. 5E and 5F, the 1 st lighting control section is set to be long, and the 2 nd lighting fixture 72 irradiates light so that the illuminance of the head region R1a becomes low, so that it can be expected that the sleep of the user becomes shallow without waking up the user. Further, by making the illuminance of the head region R1a brighter in a short time after the user's sleep becomes lighter, it is possible to suppress the user's uncomfortable feeling when getting up. Therefore, it is difficult to cause a problem that the illuminance of the bed surface rapidly increases when the user is sleeping deeply, and the user feels an increased discomfort.

< processing action >

Fig. 6 is a flowchart showing the processing operation of the rest room 1 according to the embodiment.

First, as shown in fig. 6, the user inputs the use time to the input unit 91. The input unit 91 receives the use time input, and outputs use time information, which is information indicating the use time, to the calculation unit 92. Thereby, the calculation unit 92 obtains the usage time (S11).

Next, the arithmetic unit 92 sets a1 st illumination control section as a section for prompting the user to fall asleep, an illumination fixed section as a section for prompting the user to fall asleep, and a 2 nd illumination control section as a section for prompting the user to wake up (S12).

For example, the calculation unit 92 sets the length of the 1 st illumination control section, the length of the illumination fixed section, and the length of the 2 nd illumination control section, respectively, according to the use time, even if they are changed. Specifically, the arithmetic unit 92 sets the average illuminance in the 1 st illumination control section to be 1.5 times or more the average illuminance in the illumination fixed section. The calculation unit 92 sets the length of the illumination fixed section to 20% or more of the length of the use time. The calculation unit 92 sets the length of the 2 nd illumination control section to 35% or less of the length of the usage time. The arithmetic unit 92 sets the length of the illumination fixed section to be longer than the length of the 1 st illumination control section. The calculation unit 92 sets the sum of the length of the 1 st illumination control section and the length of the illumination fixed section to be longer than the length of the 2 nd illumination control section.

The arithmetic unit 92 sets the floor surface illuminance in the 1 st illumination control section, the floor surface illuminance in the illumination fixed section, and the floor surface illuminance in the 2 nd illumination control section, respectively. Specifically, in the 1 st illumination control section, the calculation section 92 is set to a section in which the bed surface illuminance is increased by 0.03lx or more in 5 seconds and a section in which the bed surface illuminance is decreased by 0.03lx or more in 5 seconds. The calculation unit 92 sets the maximum value of the illuminance on the floor surface in the illumination fixed interval to be less than 50lx in total. In addition, the calculation unit 92 is set in a section for increasing the floor surface illuminance by 10lx or more for 10 seconds in the 2 nd illumination control section.

In this way, the arithmetic unit 92 outputs the illumination control instructions to the illumination fixture 71 so that the set 1 st illumination control interval, illumination fixed interval, and 2 nd illumination control interval are in the time-series order.

Next, when the lighting control instruction corresponding to the 1 st lighting control section is acquired, the lighting fixture 71 is turned on in accordance with the lighting control corresponding to the lighting control instruction in the 1 st lighting control section (S13). In the 1 st illumination control section, the section in which the bed surface illuminance is increased by 0.03lx or more in 5 seconds and the section in which the bed surface illuminance is decreased by 0.03lx or more in 5 seconds are included, so that the user can easily fall asleep.

Next, when the lighting control instruction corresponding to the lighting fixed zone is acquired, the lighting fixture 71 is turned on in accordance with the lighting control corresponding to the lighting control instruction in the lighting fixed zone (S14). In a certain illumination interval, the maximum value of the bed surface illumination is always less than 50lx, so that a user can sleep in a dim environment.

Next, when the lighting control instruction corresponding to the 2 nd lighting control section is acquired, the lighting fixture 71 is turned on in accordance with the lighting control corresponding to the lighting control instruction in the 2 nd lighting control section (S15). In the 2 nd illumination control section, the illuminance on the bed surface is increased by 10lx or more for 10 seconds, and thus the user becomes accustomed to the light. Thus, the user in nap can wake up without much discomfort.

< Effect >

Next, the operation and effects of the rest room 1 of the present embodiment will be described.

As described above, the lighting system 3 according to the present embodiment is a lighting system 3 that illuminates the surface of the bed 30 in which the user is sleeping, and includes the input unit 91 that inputs the usage time, the calculation unit 92 that obtains the usage time information, which is information indicating the usage time, from the input unit 91, and the lighting fixture 71 that changes the light output by receiving the lighting control instruction from the calculation unit 92. The use time includes an illumination constant interval in which the light output of the lighting fixture 71 is substantially constant. The arithmetic unit 92 changes the length of the illumination fixed section in accordance with the length of the use time indicated by the acquired use time information, and outputs an illumination control instruction corresponding to the changed illumination fixed section to the illumination fixture 71. The length of the illumination fixed interval is 20% or more of the length of the use time. The maximum value of the bed surface illuminance, which is the illuminance on the surface of the bed 30 in the illumination fixed interval, is always less than 50lx.

Thus, the maximum value of the illumination intensity of the bed surface is always less than 50lx in the illumination fixed interval, so that a dark environment can be provided for the user. Thus, the user can take a nap. Further, by setting the illumination fixed interval to be 20% or more of the length of the use time, the user can secure a time for which he can take a nap in a dark environment.

Thus, the lighting system 3 is able to ensure a nap time for the user. As a result, the user can take a rest effectively.

In the illumination system 3 of the present embodiment, the use time includes the 1 st illumination control section which is a section before the illumination fixed section. The 1 st illumination control interval includes an interval in which the floor surface illuminance is increased by 0.03lx or more for 5 seconds and an interval in which the floor surface illuminance is decreased by 0.03lx or more for 5 seconds. Then, the arithmetic unit 92 outputs the illumination control instruction corresponding to the 1 st illumination control section to the illumination fixture 71.

Thus, in the 1 st illumination control interval, the variation of light such as the brightness around the user is periodically repeated, and the user can be drowsy. Therefore, the user can easily fall asleep, and can take a rest effectively.

In the lighting system 3 of the present embodiment, the arithmetic unit 92 changes the length of the 1 st lighting control section in accordance with the length of the use time indicated by the obtained use time information, and outputs a lighting control instruction corresponding to the changed length of the 1 st lighting control section to the lighting fixture 71.

Thus, the length of the 1 st illumination control section varies depending on the use time, and therefore, the time during which the user can take a nap can be ensured to be long. Therefore, the user can effectively take a rest.

In the illumination system 3 of the present embodiment, the use time includes the 2 nd illumination control section which is a section subsequent to the illumination fixed section. The 2 nd illumination control interval includes an interval in which the bed surface illuminance is increased by 10lx or more for 10 seconds. The length of the 2 nd illumination control section is 35% or less of the length of the use time. The arithmetic unit 92 outputs an illumination control instruction corresponding to the 2 nd illumination control section to the illumination fixture 71.

For example, if the 2 nd illumination control interval is too long, there is a case where the user wakes up early. In the present embodiment, the length of the 2 nd illumination control section is set to 35% or less of the length of the usage time, whereby the user's nap time can be ensured and early waking up of the user can be suppressed. In the 2 nd illumination control interval, the illuminance on the bed surface is increased by 10lx or more for 10 seconds, and the user in a nap can wake up slowly. Therefore, the user can effectively take a rest.

In the lighting system 3 of the present embodiment, the arithmetic unit 92 changes the length of the 2 nd lighting control section in accordance with the length of the use time, and outputs a lighting control instruction corresponding to the changed length of the 2 nd lighting control section to the lighting fixture 71.

Thus, the length of the 2 nd illumination control section changes according to the use time, and therefore, the time during which the user can fall asleep can be ensured to be long. Therefore, the user can effectively take a rest.

The lighting system 3 of the present embodiment includes an input unit 91 for inputting the usage time, a calculation unit 92 for acquiring usage time information, which is information indicating the usage time acquired from the input unit 91, and a lighting fixture 71 for changing the light output by receiving a lighting control instruction from the calculation unit 92. The use time includes an illumination fixed section which is a section in which the output of light from the lighting fixture 71 is substantially fixed, a1 st illumination control section which is a section before the illumination fixed section, and a 2 nd illumination control section which is a section after the illumination fixed section. The arithmetic unit 92 changes the length of the illumination fixed section in accordance with the length of the use time indicated by the acquired use time information, and outputs an illumination control instruction corresponding to the changed illumination fixed section to the lighting fixture 71. The sum of the length of the 1 st illumination control section and the length of the illumination fixed section is longer than the length of the 2 nd illumination control section.

Thus, even if the 1 st illumination control section, the illumination fixed section, and the 2 nd illumination control section are set during the use time, the total of the length of the 1 st illumination control section and the length of the illumination fixed section is longer than the length of the 2 nd illumination control section, and therefore, the period from the user's falling asleep to the end of the nap can be ensured to be as long as possible.

Thus, in this lighting system 3, the nap time of the user can be ensured. As a result, the user can take a rest effectively.

In the illumination system 3 of the present embodiment, the length of the illumination fixed section is longer than the length of the 1 st illumination control section.

Thus, the user can have a longer nap, and a more effective rest can be obtained.

In the illumination system 3 of the present embodiment, the 1 st illumination control section includes a section in which the bed surface illuminance, which is the illuminance on the surface of the bed 30, is increased by 0.03lx or more for 5 seconds, and a section in which the bed surface illuminance is decreased by 0.03lx or more for 5 seconds. The 2 nd illumination control section includes a section in which the bed surface illuminance is increased by 10lx or more for 10 seconds. The 1 st illumination control interval, the illumination fixed interval, and the 2 nd illumination control interval are arranged in this time-series order. The arithmetic unit 92 outputs an illumination control instruction corresponding to the 1 st illumination control section, the illumination fixed section, and the 2 nd illumination control section to the illumination fixture 71.

Thus, in the 1 st illumination control interval, the fluctuation (fluctuation) of light, such as the brightness of the surroundings of the user, is periodically repeated, and the user can be drowsy. In addition, in the illumination fixed interval, the maximum value of the bed surface illumination is always less than 50lx, so that a dark environment can be provided for the user, and the user can sleep. In the 2 nd illumination control interval, the illuminance on the bed surface is increased by 10lx or more for 10 seconds, and the user in a nap can wake up slowly. Therefore, the user can effectively take a rest.

In the lighting system 3 of the present embodiment, the average illuminance in the 1 st lighting control section is 1.5 times or more the average illuminance in the lighting fixed section.

Thus, the lighting fixed interval is darker than the 1 st lighting control interval, so that an environment that is easy to fall asleep can be provided to the user in the lighting fixed interval. Therefore, the user can take a rest efficiently.

In the lighting system 3 of the present embodiment, when the usage time is less than 30 minutes, the arithmetic unit 92 changes the length of the 1 st lighting control section so that the 1 st lighting control section is less than 5 minutes, changes the length of the 2 nd lighting control section so that the 2 nd lighting control section is less than 5 minutes, and outputs a lighting control instruction corresponding to the changed length of the 1 st lighting control section and the changed length of the 2 nd lighting control section to the lighting fixture 71.

For example, according to "physiopsychology \1239225 (1): 45-59, 2007 collected sleep science 12408, lying in later noon, lying towards 1239275, lying in a short school of the university of islands: 322076, science research academy Ling, horikoshi, respectively ("physiology psychology 25 (1): 45-59), 2007 collected the contribution of psychology to sleep as a measure for afternoon sleepiness, which disclosed that the study of science Lin, jing, yang was carried out in China (" physiology psychology 25 and psychology 25 (1)), and disclosed that the study of science Lin, horiko, etc., collected the contribution of psychology to sleep in less than 30 minutes, and the sleep in more than 30 minutes was slow and became deeper sleep. For example, in a short-time nap of less than 30 minutes, the time for lighting control is shortened, and the user may feel uncomfortable when waking up due to a rapid change in brightness.

Therefore, in the present embodiment, the user can be assured a nap time by setting the light control interval 1 and the light control interval 2 to be less than 5 minutes, with less than 30 minutes as a nap. Therefore, the user can take a rest efficiently.

In the lighting system 3 of the present embodiment, when the usage time is 30 minutes or longer, the arithmetic unit 92 changes the length of the 1 st lighting control section so that the 1 st lighting control section is 5 minutes or longer, changes the length of the 2 nd lighting control section so that the 2 nd lighting control section is 5 minutes or longer, and outputs a lighting control instruction corresponding to the changed length of the 1 st lighting control section and the changed length of the 2 nd lighting control section to the lighting fixture 71.

Psychophysiology 25 (1) according to "physiopsychology 12392: 45-59, 2007 collected sleep science 12408, lying in later noon, lying towards 1239275, lying in a short school of the university of islands: 322076, science research academy Ling, horikoshi, respectively ("physiology psychology 25 (1): 45-59), 2007 collected the contribution of psychology to sleep as a measure for afternoon sleepiness, which disclosed that the study of science Lin, jing, yang was carried out in China (" physiology psychology 25 and psychology 25 (1)), and disclosed that the study of science Lin, horiko, etc., collected the contribution of psychology to sleep in less than 30 minutes, and the sleep in more than 30 minutes was slow and became deeper sleep. For example, in a short-time nap of less than 30 minutes, the time for lighting control is shortened, and the user may feel uncomfortable when waking up due to a rapid change in brightness.

Therefore, in the present embodiment, the 1 st illumination control section and the 2 nd illumination control section are set to 5 minutes or longer, considering that not only a nap but also a sleep is made for 30 minutes or longer. Therefore, a sudden change in brightness when the user wakes up is suppressed, and therefore, a feeling of discomfort due to the light of the lighting fixture 71 can be suppressed.

In the lighting system 3 of the present embodiment, the lighting fixtures 71 perform lighting control at a constant cycle in the 1 st lighting control interval. The length of the 1 st illumination control section is substantially an integer multiple of a fixed period.

Thus, in the 1 st illumination control interval, the light fluctuation such as the indoor space brightness or dimming is periodically repeated around the user. Thus, since there is continuity in the change of the brightness of light and there is no abrupt change, the user does not feel uncomfortable and can easily fall asleep.

Further, since the lighting fixture 71 increases or decreases the light output only repeatedly, the control of the lighting fixture 71 is easy. Therefore, the handling of the illumination system 3 is not easily complicated.

In the lighting system 3 according to the present embodiment, the arithmetic unit 92 turns off the driving of the lighting fixture 71 in any one of the 1 st lighting control section and the 2 nd lighting control section.

Thus, when the lighting control in the 1 st lighting control section or the 2 nd lighting control section is not favorable, the user can stop the lighting control in any section. Therefore, the user can selectively use the preferred illumination control section. As a result, the convenience of the lighting system 3 becomes high.

The lighting system 3 of the present embodiment includes at least 1 of the sound device 61, the blower 62, and the fragrance unit 63, the control device 60 that controls at least 1 of the sound device 61, the blower 62, and the fragrance unit 63, and the operation device 40 that operates at least 1 of the sound device 61, the blower 62, and the fragrance unit 63.

This enables control of at least 1 of the acoustic device 61, the blower 62, and the fragrance unit 63, thereby providing a comfortable nap environment to the user.

The rest room 1 of the present embodiment further includes 1 or more wall portions 11f arranged around the bed 30, a ceiling 13, and an illumination system 3.

Thus, by using a kit in which a cell (room 10) including the wall portion 11f and the top plate 13 is combined with the lighting system 3, it is possible to easily set the bed surface illuminance, particularly, the bed surface illuminance in the head region R1a to a desired illuminance.

In the rest room 1 of the present embodiment, the outer dimensions of the rest room 1 are 1100mm or less, 2100mm or less, and 1950mm or less. The lower limit of the outer dimensions of the rest room 1 is 600mm to 1900mm to 1000 mm.

Thus, if the lobby 1 has such an outer dimension, the lobby 1 can be easily carried in and out because the lobby is of a size that allows the elevator to be ridden.

Further, the use space of the user in the indoor space R can be secured, and the enlargement of the lounge 1 can be suppressed to such an extent that the user does not feel oppressed. Specifically, the rest room 1 is set to be about 50cm or more in shoulder width of a person, further set to be capable of lying down by a person 190cm in height, and further set to be about 90cm or more in sitting height of a person. Therefore, a space in which the person can lie on his back for sleeping can be secured.

The rest room 1 of the present embodiment further includes a moving unit.

This makes it possible to provide a movable lounge 1 that can be freely moved.
