[0012] In the following embodiments, expressions such as substantially parallel are used. For example, substantially parallel or rectangular parallelepiped-shaped not only means being completely parallel or a rectangular parallelepiped, but also means being substantially parallel or a rectangular parallelepiped, that is, including an error of about several percent, for example. Also, substantially parallel or rectangular parallelepiped-shaped means parallel or a rectangular parallelepiped within the range where the effects according to the present disclosure can be achieved. The same applies to other expressions using "substantially" or "shaped".

[0013] In the following embodiments, the longitudinal direction of the bed is defined as the X-axis direction, the short-side direction of the bed is defined as the Y-axis direction, and the direction orthogonal to the X-axis direction and the Y-axis direction is defined as the Z-axis direction. Further, the head side of the user lying in the bed in the X-axis direction is defined as the positive X-axis direction side, the left hand side of the user lying on the back in the bed is defined as the positive Y-axis direction side, and the vertical direction side with respect to the user lying in the bed is defined as the positive Z-axis direction side.

[0014] Hereinafter, the embodiments will be specifically described with reference to the drawings.

[0015] (Embodiment) <Configuration: Rest Room 1> First, the configuration of Rest Room 1 in the present embodiment will be described.

[0016] FIG. 1 is a perspective view showing the appearance of Rest Room 1 according to the embodiment.

[0017] As shown in FIG. 1, Rest Room 1 forms an indoor space R in which a bed 30 for a user to sleep or rest is accommodated. The user can reduce drowsiness and relieve fatigue by sleeping or resting in the indoor space R.

[0018] In addition, in Rest Room 1, the indoor space R can be illuminated. For example, when the user uses it as a nap room, when setting the desired wake-up time, it can be set to start lighting from a time before the desired wake-up time. Also, when the user uses it as Rest Room 1, the indoor space R can be illuminated. In the present embodiment, waking up includes not only the user getting up from the bed but also simply waking up.

[0019] In addition, in Rest Room 1, the air quality of the indoor space R can be adjusted by taking in air from the external space or the like. The air quality refers to the temperature, humidity, amount of fragrance components, etc. of the air in the indoor space R.

[0020] In addition, the rest room 1 is provided with casters 12. Therefore, the rest room 1 can be freely moved by the rotation of the wheels of the casters 12. Also, the rest room 1 can be arranged in a non-movable state by locking the casters 12.

[0021] In addition, the rest room 1 is set to a size that can be placed in an elevator. Specifically, the outer dimensions of the rest room 1, that is, the length (width) along the Y-axis direction of the rest room 1 × the length along the X-axis direction of the rest room 1 × the length (height) along the Z-axis direction of the rest room 1 are 1100 mm or less × 2100 mm or less × 1950 mm or less.

[0022] Also, the rest room 1 is set to a size that allows a person to sleep in a normal standing position. Specifically, the lower limit values of the outer dimensions of the room Ⅰ, that is, the lower limit values of the length (width) along the Y-axis direction of the rest room 1 × the length along the X-axis direction of the rest room 1 × the length (height) along the Z-axis direction of the rest room 1 are 600 mm or more × 1900 mm or more × 1000 mm or more. That is, in the rest room 1, by setting the lower limit value of the width to 600 mm or more, it can be set to about 50 cm or more, which is the shoulder width of a person. Also, in the rest room 1, by setting the lower limit value of the length to 1900 mm or more, a person with a height of 190 cm can lie down in the rest room 1. Also, in the rest room 1, by setting the lower limit value of the height to 1000 mm or more, it can be set to about 90 cm or more, which is the sitting height of a person.

[0023] Hereinafter, the specific configuration of the rest room 1 will be described.

[0024] The rest room 1 includes a room 10, a duct 20, and a lighting system 3.

[0025] [Room 10] Room 10 is provided with an entrance / exit 19 through which users enter and exit. In the present embodiment, the entrance / exit 19 is provided on the minus Y-axis direction side in Room 10 and at the central portion in the X-axis direction of Room 10. In FIG. 1, although a door capable of opening and closing the entrance / exit 19 is not illustrated, the entrance / exit 19 may be provided with a door.

[0026] Further, Room 10 forms an indoor space R where users sleep. Since a long bed 30 is arranged in Room 10, the indoor space R is long along the X-axis direction according to the size of the bed 30.

[0027] FIG. 2 is a block diagram showing the rest room 1 according to the embodiment.

[0028] As shown in FIGS. 1 and 2, Room 10 is a rectangular parallelepiped-shaped housing formed in a size that allows users to sleep. Room 10 houses a bed 30, a duct 20, an operating device 40, a first lighting fixture 71, a second lighting fixture 72, a wake-up time setting unit 90, an audio device 61, a blower 62, an aroma diffuser 63, and a power supply unit 80. Note that for the audio device 61, the blower 62, and the aroma diffuser 63, at least one of the audio device 61, the blower 62, and the aroma diffuser 63 may be installed in Room 10.

[0029] FIG. 3 is a view showing the indoor space R of the rest room 1 according to the embodiment.

[0030] As shown in FIGS. 1 and 3, when the indoor space R of Room 10 is viewed from above along the minus Z-axis direction, the indoor space R includes a first space R1 for users to sleep, a second space R2 between the bed 30 and the long side of Room 10 on the entrance / exit 19 side, and a third space R3 between the bed 30 and the long side of Room 10 on the entrance / exit 19 side and located on the foot side when the user sleeps in the bed 30. The first space R1 is indicated by dot hatching, the second space R2 is indicated by diagonal hatching, and the third space R3 is indicated by grid hatching.

[0031] The second space R2 and the third space R3 are located on the minus Y-axis direction side with respect to the first space R1. Further, the third space R3 is located on the minus X-axis direction side with respect to the second space R2, and is located on the foot side when the user goes to bed on the bed 30. An operating device 40, a bed 30, etc. are arranged in the first space R1, the floor board 11b of the room 10 is arranged in the second space R2, and a blower 62, an aromatherapy device 63, a second lighting fixture 72, a power supply unit 80 shown in FIG. 2, etc. are arranged in the third space R3.

[0032] As shown in FIG. 1, the room 10 includes a plurality of frameworks 11, a plurality of casters 12, a plurality of wall portions 11f, and a ceiling 13.

[0033] The plurality of frameworks 11 include a frame-shaped base 11a, a floor board 11b, a plurality of columns 11c, and an upper frame 11d.

[0034] The base 11a is a rectangular frame body and is arranged vertically below the room 10 (in the minus Z-axis direction) so as to be substantially parallel to the XY plane. A plurality of casters 12 corresponding one-to-one to at least each corner portion are provided on the end surface on the minus Z-axis direction side of the base 11a. For this reason, the base 11a is arranged so as to face the ground via the casters 12.

[0035] The caster 12 can rotate the wheels when the room 10 moves with respect to the ground, or lock the wheels so that they do not rotate. The caster 12 is an example of a moving part.

[0036] A plurality of large pulls 11a1 are connected to the base 11a. A floor board 11b is provided on the base 11a and the plurality of large pulls 11a1. The floor board 11b is long along the X-axis direction. The floor board 11b is located between the bed 30 and the entrance 19 of the room 10, and is arranged on the base 11a and the plurality of large pulls 11a1 in the second space R2.

[0037] The plurality of columns 11c are elongated and extend along the Z-axis direction from respective corner portions of the base 11a, and support the upper frame 11d.

[0038] Also, some of the plurality of columns 11c are provided adjacent to each other to form the third space R3. Specifically, some of the columns 11c for forming the third space R3 are constituted by at least the first column 11c1, the second column 11c2, and the third column 11c3. The first column 11c1 is disposed at a corner portion that is an end portion in the minus X-axis direction and an end portion in the minus Y-axis direction of the base 11a. The second column 11c2 is adjacent to the first column 11c1 and is disposed in the plus X-axis direction with respect to the first column 11c1. The third column 11c3 is adjacent to the first column 11c1 and is disposed in the plus Y-axis direction with respect to the first column 11c1.

[0039] The plurality of wall portions 11f are partitions for defining the indoor space R. Some of the plurality of wall portions 11f are disposed between two adjacent columns 11c among the plurality of columns 11c.

[0040] In FIG. 1, illustration of the wall portion 11f is omitted except for the first wall portion 11f1 and the second wall portion 11f2. One or more wall portions 11f are disposed around the bed 30, and are disposed, for example, at least on any one of the front, rear, left, and right sides with respect to the bed 30.

[0041] Also, the first wall portion 11f1 and the second wall portion 11f2, which are some of the plurality of wall portions 11f, are disposed around the air blower 62, the aromatherapy device 63, and the like. The first wall portion 11f1 is disposed between the first column 11c1 and the second column 11c2. The second wall portion 11f2 is disposed between the first column 11c1 and the third column 11c3. Also, the first wall portion 11f1 and the second wall portion 11f2 constitute a part of the short side of the room 10 as an outer wall (outer shell) of the room 10. The first wall portion 11f1 and the second wall portion 11f2 are examples of the wall portion 11f.

[0042] Further, the second column 11c2 is connected to a light-shielding portion 11f3 that extends from the second column 11c2 along the positive Y-axis direction and is disposed between the second space R2 and the third space R3.

[0043] The upper frame 11d is a rectangular frame body and is disposed vertically above (in the positive Z-axis direction) the room 10 so as to be substantially parallel to the XY plane. The upper frame 11d corresponds to the base 11a and is supported by a plurality of columns 11c. In the present embodiment, two upper frames 11d are provided. Between the two upper frames 11d, the first lighting fixture 71 and the duct 20 are disposed.

[0044] The upper frame 11d is provided with a ceiling 13. The ceiling 13 is provided with the duct 20 and an air outlet 20a that is an opening of the duct 20. The duct 20 guides the air sucked from the suction port 20b to the air outlet 20a. That is, the duct 20 forms a flow path through which air flows by connecting the air outlet 20a and the suction port 20b.

[0045] The air outlet 20a blows out the air sucked from the suction port 20b and passed through the duct 20. The air outlet 20a is disposed on the upper body side or the lower body side when the user goes to bed on the bed 30. In the present embodiment, the air outlet 20a is attached to the ceiling 13 facing the bed 30 and is disposed at a position facing the lower body side when the user goes to bed on the bed 30.

[0046] Further, the air outlet 20a is disposed away from the suction port 20b and the blower 62. That is, the wall portion 11f (i.e., the ceiling 13) of the room 10 where the air outlet 20a is disposed and the wall portion 11f of the room 10 where the suction port 20b is disposed are separate wall portions 11f. In this way, by separating the air outlet 20a and the suction port 20b as much as possible, the sound and light entering from the suction port 20b are prevented from being transmitted to the air outlet 20a.

[0047] The suction port 20b is arranged on the foot side when the user goes to bed on the bed 30. Further, the suction port 20b is provided on the outer wall of the room 10 so as to face the external space of the room 10. Therefore, the suction port 20b can suck air from the external space of the room 10. In the present embodiment, the suction port 20b is arranged to face the blower 62 so as to communicate the external space with the third space R3.

[0048] [Lighting system 3] As shown in FIGS. 1 and 2, when the user sets the wake-up desired time, the lighting system 3 executes a mode for waking up the user in order to wake up the user at the wake-up desired time. The mode is a mode for waking up the user by turning on the first lighting fixture 71 and the second lighting fixture 72.

[0049] Specifically, the lighting system 3 includes a bed 30, an operating device 40, a control device 60, a first lighting fixture 71, a second lighting fixture 72, a light-shielding portion 11f3, a wake-up time setting portion 90, an acoustic device 61, a blower 62, an aromatherapy device 63, and a power supply portion 80. Note that the lighting system 3 may only include at least one of the acoustic device 61, the blower 62, and the aromatherapy device 63, and does not necessarily include all of these devices.

[0050] The bed 30 allows the user to sit and go to bed. Further, the bed 30 is elongated along the X-axis direction in the first space R1. The bed 30 of the present embodiment is supported by a plurality of columns 11c, but may be placed on a base 11a and a plurality of large draws 11a1.

[0051] In the bed 30, it is set such that the head of the user is located on the positive X-axis direction side of the bed 30 and the feet are located on the positive X-axis direction side of the bed 30.

[0052] In addition, the bed 30 of the present embodiment includes those that function as a bed when the chair is deformed. Specifically, the bed 30 may have a seat portion on which a user sits, a footrest rotatably connected to the seat portion, a backrest rotatably connected to the seat portion, and a headrest connected to the backrest. In this case, the chair may function as a bed in which the footrest, seat portion, backrest, and headrest are arranged in a straight line. Further, the bed 30 of the present embodiment can be inclined and may be deformed like a chair. In the case of a chair, when the user leans their back against the backrest and places their head on the headrest, the illuminance of the surface of the backrest and the illuminance of the surface of the headrest correspond to the illuminance of the bed surface in the head region R1a.

[0053] The operating device 40 is arranged on the positive X-axis side of the bed 30 in the first space R1. That is, when the user goes to bed on the bed 30, the operating device 40 is arranged near the head. The operating device 40 may be arranged in one or more of the first space R1, the second space R2, and the third space R3. That is, a plurality of operating devices 40 may be provided in the rest room 1.

[0054] In addition, the user can individually operate each of the audio device 61, the blower 62, and the aromatherapy device 63 with the operating device 40. That is, the operating device 40 outputs an instruction operated by the user to the control device 60, and the control device 60 drives or stops driving each of the audio device 61, the blower 62, and the aromatherapy device 63. The operating device 40 may only be able to operate at least one of the audio device 61, the blower 62, and the aromatherapy device 63. Further, the operating device 40 may be able to individually operate each of the first lighting fixture 71 and the second lighting fixture 72.

[0055] The control device 60 can control each of the audio device 61, the blower 62, and the aroma diffuser 63 according to an instruction from the operation device 40. Note that the control device 60 may only control at least one of the audio device 61, the blower 62, and the aroma diffuser 63. Further, the control device 60 may be able to control the first lighting fixture 71 and the second lighting fixture 72.

[0056] Here, control of the audio device 61, the blower 62, and the aroma diffuser 63 by the control device 60 will be described.

[0057] For example, when the user operates the operation device 40 to input an instruction, the control device 60 instructs the audio device 61 to play music according to the instruction acquired from the operation device 40. As a result, when the audio device 61 plays music, the reproduced music is output into the indoor space R. Further, by acquiring an instruction from the operation device 40, the control device 60 can change the music played by the audio device 61 or control the volume of the music output by the audio device 61.

[0058] Also, when the user operates the operation device 40 to input an instruction so that the blower 62 changes from the OFF state to the ON state, the control device 60 turns on the power of the blower 62 according to the instruction acquired from the operation device 40. As a result, when the blower 62 is driven, the air in the external space is taken into the indoor space R of the room 10. Further, by acquiring an instruction from the operation device 40, the control device 60 can control the output of the blower 62, that is, the rotation speed of the fan in the blower 62.

[0059] Also, when the user operates the operation device 40 to input an instruction so that the aroma diffuser 63 changes from the OFF state to the ON state, the control device 60 turns on the power of the aroma diffuser 63 according to the instruction acquired from the operation device 40. As a result, when the aroma diffuser 63 is driven, the fragrance of the aroma diffuser 63 is introduced into the air in the indoor space R. Further, by acquiring an instruction from the operation device 40, the control device 60 can control the output of the aroma diffuser 63, that is, the amount of fragrance introduced into the indoor space R.

[0060] The first lighting fixture 71 and the second lighting fixture 72 can illuminate the indoor space R. Also, the first lighting fixture 71 and the second lighting fixture 72 have a dimming function for changing the light quantity. For example, the first lighting fixture 71 and the second lighting fixture 72 execute dimming control by acquiring a dimming instruction from the wake-up time setting unit 90. Thereby, the first lighting fixture 71 and the second lighting fixture 72 can change the luminance (brightness) of the emitted light. Note that at least one of the first lighting fixture 71 and the second lighting fixture 72 may have a dimming function for changing the light quantity.

[0061] Also, the first lighting fixture 71 and the second lighting fixture 72 may be dimmed and color-adjusted according to a direct instruction from the operation device 40.

[0062] Also, the first lighting fixture 71 is disposed vertically above the upper body of the user when the user goes to bed on the bed 30. Specifically, the first lighting fixture 71 is provided on the ceiling 13. Also, the first lighting fixture 71 is disposed so as to be embedded in the ceiling 13. Note that the first lighting fixture 71 may be provided within the indoor space R. More specifically, as shown in FIG. 4, the first lighting fixture 71 may be disposed such that the distance from the head region R1a, which is the region where the head of the user is located when the user goes to bed on the bed 30, is 1.5 m or less. FIG. 4 is a diagram showing the distance between the head region R1a and the first lighting fixture 71 of the rest room 1 according to the embodiment. Here, the head region R1a is the region of the surface of the bed 30 where the head of the user is located when the user goes to bed on the bed 30.

[0063] The second lighting fixture 72 is installed on the foot side when the user goes to bed on the bed 30. Specifically, the second lighting fixture 72 is disposed in the third space R3. Also, a plurality of second lighting fixtures 72 may be provided in the third space R3. Also, the second lighting fixture 72 may be disposed so as to be embedded in the light shielding portion 11f3.

[0064] The light-shielding portion 11f3 is disposed between the second lighting fixture 72 and the head region R1a. Specifically, the light-shielding portion 11f3 is on the foot side when the user goes to bed on the bed 30, and is disposed at the boundary between the first space R1 and the third space R3. For this reason, the light-shielding portion 11f3 is substantially parallel to the YZ plane, and can shield the head of the user when the user goes to bed on the bed 30 from being directly irradiated with the light emitted from the second lighting fixture 72.

[0065] Further, the light-shielding portion 11f3 is disposed to face the second wall portion 11f2 via the second lighting fixture 72. For this reason, the light-shielding portion 11f3 forms an opening 11h through which the light irradiated by the second lighting fixture 72 passes together with the second wall portion 11f2. As a result, when the second lighting fixture 72 is lit, the light emitted from the second lighting fixture 72 is reflected by the light-shielding portion 11f3 and the second wall portion 11f2 and emitted from the opening 11h, and is further reflected by the wall portion 11f of the room 10, the bed 30, etc. and irradiated onto the head region R1a.

[0066] The wake-up time setting unit 90 has a switch, a touch panel, or the like that enables the user to set their wake-up time when going to bed on the bed 30. By setting the wake-up time, the wake-up time setting unit 90 controls the driving of the first lighting fixture 71 and the second lighting fixture 72. Specifically, when the wake-up time setting unit 90 receives an input of the desired wake-up time by the user's operation, it can change the light amount of at least one of the first lighting fixture 71 and the second lighting fixture 72 from t seconds before the desired wake-up time. More specifically, by outputting an instruction of the desired wake-up time input to the wake-up time setting unit 90, at least one of the first lighting fixture 71 and the second lighting fixture 72 is driven from t seconds before the desired wake-up time. Thereby, at least one of the first lighting fixture 71 and the second lighting fixture 72 starts lighting from t seconds before the desired wake-up time. Thus, the wake-up time setting unit 90 may have a lighting control unit that controls the driving of the first lighting fixture 71 and the second lighting fixture 72. Further, such a lighting control unit may be arranged separately and independently from the wake-up time setting unit 90, may be mounted on the control device 60, or may be mounted on each of the first lighting fixture 71 and the second lighting fixture 72.

[0067] Here, the t seconds is a preset time, but it is preferably 900 seconds or less, for example. This is because if the user uses the rest room 1 for a short nap and goes to bed, if t seconds becomes too long compared to 900 seconds, the user's short nap time will be shortened. Therefore, by setting the upper limit value of t seconds to 900 seconds, it is possible to ensure a sufficient short nap time for the user.

[0068] In addition, the wake-up time setting unit 90 changes the light amount of at least one of the first lighting fixture 71 and the second lighting fixture 72, and changes the bed surface illuminance, which is the illuminance of the surface of the bed 30 in the head region R1a, over time until the desired wake-up time. That is, at least one of the first lighting fixture 71 and the second lighting fixture 72 changes the light amount of the emitted light from t seconds before the desired wake-up time until the desired wake-up time, so that the bed surface illuminance changes over time. Here, changing over time means that there is a change of ±10 lx or more in 60 seconds in the bed surface illuminance. Note that it is preferable that the bed surface illuminance gradually increases over time.

[0069] Here, the bed surface illuminance is the illuminance of the surface of the bed 30 when at least one of the first lighting fixture 71 and the second lighting fixture 72 is lit. Therefore, the bed surface illuminance in the head region R1a is the illuminance of the surface of the bed 30 where the head is placed when the user goes to bed on the bed 30. In the present embodiment, the bed surface illuminance in the head region R1a is regarded as being equivalent to the illuminance of the head of the user who has gone to bed on the bed 30, that is, the face illuminance.

[0070] In addition, the wake-up time setting unit 90 is arranged on the side opposite to the side where the second lighting fixture 72 is arranged in the longitudinal direction of the bed 30. That is, the wake-up time setting unit 90 is arranged on the head side when the user goes to bed on the bed 30. Therefore, the user can operate the wake-up time setting unit 90 while lying in bed.

[0071] In addition, the wake-up time setting unit 90 may be integrally configured with the operation device 40. Further, the wake-up time setting unit 90 may be configured separately and independently from the operation device 40.

[0072] The audio device 61 can provide the user with music having a sleep-inducing effect or music having a wake-up effect by playing music in the room 10. The audio device 61 is housed in the room 10 and is arranged, for example, in the indoor space R. The audio device 61 can change the music played in the indoor space R or adjust the volume by the user operating the operating device 40.

[0073] The blower 62 is arranged in the room 10, sucks air from the suction port 20b provided in the room 10, and blows out air from the blowout port 20a provided in the indoor space R, thereby generating an air flow in the indoor space R. The blower 62 can adjust the temperature, humidity, etc. of the air in the indoor space R by driving to take in the air in the external space.

[0074] Thereby, the blower 62 can generate an air flow from the suction port 20b toward the blowout port 20a by driving in a state of being arranged on the suction port 20b side of the duct 20. Further, since the blower 62 can blow out air from the blowout port 20a, it is possible to strengthen or stop blowing the air against the user who has gone to bed on the bed 30. The output of the blower 62 can be adjusted by the operating device 40.

[0075] Further, the blower 62 is arranged on the foot side when the user goes to bed on the bed 30. Also, the blower 62 is arranged on the flow path in the duct 20. In the present embodiment, the blower 62 is at the same height as the suction port 20b so as to face the suction port 20b in the third space R3, and is arranged closer to the ceiling 13 than the bed 30 so as to be away from the user's head.

[0076] The aroma diffuser 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 aroma diffuser 63 can include the fragrance in the air flowing from the suction port 20b toward the air outlet 20a by driving the blower 62 under the control of the control device 60. That is, the fragrance is guided into the indoor space R by being carried on the air current flowing from the suction port 20b toward the air outlet 20a. Thereby, the indoor space R can be filled with a fragrance that the user enjoys. The output of such an aroma diffuser 63 can be adjusted by the operation device 40.

[0077] Note that the aroma diffuser 63 can introduce the fragrance into the indoor space R without driving the blower 62. That is, the aroma diffuser 63 can simply be disposed in the indoor space R and fill the indoor space R with the fragrance of the fragrance.

[0078] Also, the aroma diffuser 63 is disposed on the foot side when the user goes to bed on the bed 30. Specifically, the aroma diffuser 63 is disposed on the flow path in the duct 20 or in the third space R3. In the present embodiment, the aroma diffuser 63 is on the downstream side (the air outlet 20a side) of the blower 62 and is disposed closer to the ceiling 13 than the blower 62 so as to be away from the user's head.

[0079] Note that in the present embodiment, the blower 62 and the aroma diffuser 63 are located on the side in the negative Z-axis direction (downward side) from the ceiling 13, but it is not limited thereto. It is also possible that only the blower 62 is located on the side in the negative Z-axis direction from the ceiling 13. Note that in the present embodiment, the blower 62 and the aroma diffuser 63 are disposed on the foot side when the user goes to bed on the bed 30, but it is not limited thereto. It is also possible that only the blower 62 is disposed on the foot side when the user goes to bed on the bed 30. In these cases, the aroma diffuser 63 may be disposed above the ceiling 13 or may be disposed near the air outlet 20a of the duct 20.

[0080] The power supply unit 80 controls the light output by supplying power to the first lighting fixture 71 and the second lighting fixture 72, or controls the output by supplying power to the audio device 61, the blower 62, and the aroma diffuser 63. That is, the power supply unit 80 generates drive power for driving the first lighting fixture 71, the second lighting fixture 72, the audio device 61, the blower 62, and the aroma diffuser 63, and supplies this drive power to each of the first lighting fixture 71, the second lighting fixture 72, the audio device 61, the blower 62, and the aroma diffuser 63.

[0081] [Bed surface illuminance] Here, when the lighting system 3 executes the lighting mode for waking up the user, the bed surface illuminance in the head region R1a from t seconds before the desired wake-up time to the desired wake-up time will be described.

[0082] As shown in FIG. 5A, the section from t seconds before the desired wake-up time to t1 seconds before the desired wake-up time when more time has elapsed than t seconds is defined as the first section, and the section from t1 seconds to the desired wake-up time is defined as the second section. FIG. 5A is a diagram showing the bed surface illuminance from t seconds before the desired wake-up time to the desired wake-up time.

[0083] In the first section, the second lighting fixture 72 lights up so that the time average value of the bed surface illuminance in the head region R1a is less than 100 lx. Also, in the first section, when the second lighting fixture 72 lights up, the maximum value of the bed surface illuminance in the head region R1a becomes 1 lx or more. Also, in the first section, the first lighting fixture 71 is turned off. This is because if a sleeping user is suddenly exposed to bright light, the user will suddenly wake up and feel discomfort. Therefore, in the first section, the wake-up time setting unit 90 controls the second lighting fixture 72 so that the bed surface illuminance in the head region R1a is less than 100 lx and 1 lx or more, making it difficult to wake up the user, that is, making it dim, like a night light. Thereby, in the first section, the sleeping user can get used to the light of the second lighting fixture 72.

[0084] In the second period, at least the first lighting fixture 71 lights up so that the maximum value of the illuminance on the bed surface in the head region R1a is 100 lx or more. For example, in the second period, when only the first lighting fixture 71 lights up, the maximum value of the temporal illuminance on the bed surface in the head region R1a is 100 lx or more. Also, in the second period, mainly the first lighting fixture 71 is in the lit state, but the second lighting fixture 72 may also light up. In this case, in the second period, the first lighting fixture 71 may turn off when the illuminance of the head by the second lighting fixture 72 reaches a certain brightness. As a result, since it is difficult for the user to notice the turning off of the first lighting fixture 71, it is difficult for the user to feel a sense of discomfort due to the turning off. Consequently, an increase in power consumption in the lighting system 3 can be suppressed.

[0085] Here, the second period is preferably in the range of, for example, approximately 60 seconds to 600 seconds. By setting the upper limit value of the second period to 600 seconds, the time when the first lighting fixture 71 lights up and directly irradiates light on the user's head can be made as late as possible. Thereby, the user's dozing time can be ensured. Also, by setting the lower limit value of the second period from 60 seconds, it is possible to prevent the brightness of the light directly irradiating the user's head from changing abruptly due to the lighting of the first lighting fixture 71. Thus, it is possible not to give the user an uncomfortable feeling due to this abrupt change in brightness.

[0086] Also, in the second period, the maximum value of the temporal illuminance on the bed surface in the head region R1a is 700 lx or more. Specifically, in the second period, when the second - 1 period and the second - 2 period, which is a period after the second - 1 period, are set, in the second - 2 period, the maximum value of the temporal illuminance on the bed surface in the head region R1a is 700 lx or more. That is, in the second period, at a time close to the desired wake - up time, the maximum value of the temporal illuminance on the bed surface in the head region R1a is 700 lx or more. Specifically, at a later time close to the desired wake - up time, at least the first lighting fixture 71 irradiates high - intensity light so that the illuminance on the bed surface in the head region R1a is 700 lx or more. For this reason, the user can wake up.

[0087] Also, in the second - 1 section, the maximum value of the bed - surface illuminance in the head region R1a is 100 lx or more. That is, in the second - 1 section, in order to wake up the user, it is made brighter than the bed - surface illuminance in the head region R1a of the first section.

[0088] Also, the time when the bed - surface illuminance in the head region R1a is 700 lx or more is in the range of approximately 10 seconds to 60 seconds.

[0089] t seconds is set by the wake - up time setting unit 90 according to the length of the bedtime period, which is the period from the time when the user starts going to bed, that is, the time when the user sets the desired wake - up time in the wake - up time setting unit 90 to the desired wake - up time. That is, when the length of the bedtime period, which is the period from the time when the desired wake - up time is set to the desired wake - up time, becomes longer, the wake - up time setting unit 90 sets t seconds longer. On the other hand, when the length of the bedtime period, which is the period from the time when the desired wake - up time is set to the desired wake - up time, becomes shorter, the wake - up time setting unit 90 sets t seconds shorter.

[0090] Here, the lighting control period including the first section and the second section will be described with reference to FIGS. 5A to 5F.

[0091] The second sections of FIGS. 5A to 5C, 5E, and 5F illustrate the case where the second section is longer than the second section of FIG. 5D, and FIG. 5D illustrates the case where the second section is short. Note that the lighting control in FIGS. 5A to 5F is merely an example, and the lighting system 3 is not limited to FIGS. 5A to 5F.

[0092] For example, as shown in FIG. 5A, the first section may be set short and the second section may be set longer than the first section.

[0093] Next, FIG. 5B is another diagram showing the illuminance on the bed surface from t seconds before the desired wake-up time to the desired wake-up time. As shown in FIG. 5B, the first section may be set shorter and the second section may be set longer than the first section. Also, in the first section of FIG. 5B, the wake-up time setting unit 90 may set a period with a darker bed surface brightness than the first section of FIG. 5A to be longer, and in the second section of FIG. 5B, a period with a brighter bed surface brightness than the second section of FIG. 5A may be set shorter. Furthermore, in FIG. 5B, the period during which the bed surface illuminance reaches the maximum value may be set shorter than in FIG. 5A.

[0094] Next, FIG. 5C is another diagram showing the illuminance on the bed surface from t seconds before the desired wake-up time to the desired wake-up time. Also, as shown in FIG. 5C, the first section may be set longer and the second section may be set shorter than the first section. Also, in the first section of FIG. 5C, the wake-up time setting unit 90 may set a period with a darker bed surface brightness than the first section of FIG. 5B to be longer, and in the second section of FIG. 5C, a period with a brighter bed surface brightness than the second section of FIG. 5B may be set shorter. Furthermore, in FIG. 5C, the period during which the bed surface illuminance reaches the maximum value may be set shorter than in FIG. 5B.

[0095] Next, FIG. 5D is yet another diagram showing the illuminance on the bed surface from t seconds before the desired wake-up time to the desired wake-up time. Also, as shown in FIG. 5D, the first section may be set longer and the second section may be set shorter than the first section. Also, the wake-up time setting unit 90 may set a period with a darker bed surface brightness than the first section of FIG. 5C to be longer in the first section of FIG. 5D, and a period with a brighter bed surface brightness than the second section of FIG. 5C may be set shorter in the second section of FIG. 5D.

[0096] Next, FIG. 5E is a diagram showing a case where the illuminance on the bed surface is low from t seconds before the desired wake-up time to the desired wake-up time. Also, as shown in FIG. 5E, the wake-up time setting unit 90 may have a first section in which the bed surface illuminance increases very gently and a second section in which the bed surface illuminance increases more steeply than the first section. In this case, the second lighting fixture 72 illuminates, but in the first section, the bed surface illuminance is very low, that is, the bed surface is dark. Also, in the second section, the bed surface illuminance suddenly increases and becomes bright.

[0097] Next, FIG. 5F is another diagram showing a case where the illuminance on the bed surface is low from t seconds before the desired wake-up time to the desired wake-up time. Also, as shown in FIG. 5F, the wake-up time setting unit 90 may have a first section in which the illuminance on the bed surface is gradually increased and a second section in which the illuminance on the bed surface is increased more rapidly than in the first section. In this case, the second lighting fixture 72 illuminates, but in the first section, the illuminance on the bed surface is low, that is, the bed surface is dim. In the second section, the illuminance on the bed surface rapidly increases and becomes bright.

[0098] In FIGS. 5A to 5D, when the user's light sleep time is short, the user may want to secure as much light sleep time as possible. In this case, even if a lighting control period as shown in FIG. 5A is set, the user may select a lighting control with a shorter lighting control period such as in FIGS. 5B and 5C. In this way, the user may be able to select a lighting control with a shorter lighting control period than in FIG. 5A according to his or her preference by operating the operation device 40.

[0099] Also, in FIGS. 5E and 5F, by setting the first section long and irradiating the second lighting fixture 72 with light so that the illuminance in the head region R1a becomes low, it can be expected to make the user's sleep shallow so as not to wake up the user. Then, by making the illuminance in the head region R1a bright within a short time after the user's sleep becomes shallow, the discomfort at the time of the user's wake-up can be suppressed. For this reason, when the user is in a deep sleep, it is less likely to cause a problem that the user's discomfort increases due to the sudden increase in the illuminance on the bed surface.

[0100] <Processing operation> FIG. 6 is a flowchart showing the processing operation of the rest room 1 according to the embodiment.

[0101] First, the user inputs the desired wake-up time to the wake-up time setting unit 90. Thereby, as shown in FIG. 6, the wake-up time setting unit 90 obtains the desired wake-up time by accepting the input of the desired wake-up time (S11).

[0102] Next, the wake-up time setting unit 90 calculates a bedtime period, which is the period from the time when the desired wake-up time is set to the desired wake-up time. Then, the wake-up time setting unit 90 sets the time to start lighting the second lighting fixture 72 from a time before the desired wake-up time according to the length of the bedtime period. Specifically, the wake-up time setting unit 90 sets t seconds, which is the time for executing lighting by the first lighting fixture 71 and the second lighting fixture 72 to wake up the user (S12). That is, the wake-up time setting unit 90 sets the time t seconds before the desired wake-up time.

[0103] Next, the wake-up time setting unit 90 determines whether it is t seconds before the desired wake-up time (S13).

[0104] If the wake-up time setting unit 90 is not t seconds before the desired wake-up time (NO in S13), the processing operation returns to step S13.

[0105] On the other hand, if the wake-up time setting unit 90 is t seconds before the desired wake-up time (YES in S13), it starts lighting the second lighting fixture 72 (S14). That is, the lighting system 3 starts executing the lighting mode for waking up the user. Specifically, in the first section from t seconds before the desired wake-up time to t1 seconds before the desired wake-up time, the wake-up time setting unit 90 lights only the second lighting fixture 72 so that the maximum value of the bed surface illuminance in the head region R1a becomes 1 lx or more, and gradually increases the light amount of the second lighting fixture 72. The light emitted by the second lighting fixture 72 is blocked by the light shielding portion 11f3, so that the light is not directly irradiated on the user's head, and the bed surface in the head region R1a becomes dim.

[0106] Next, the wake-up time setting unit 90 determines whether it is t1 seconds before the desired wake-up time (S15).

[0107] If the wake-up time setting unit 90 is not t1 seconds before the desired wake-up time (NO in S14), the processing operation returns to step S14.

[0108] On the other hand, when it is t1 seconds before the desired wake-up time (YES in S14), the wake-up time setting unit 90 starts lighting at least the first lighting fixture 71 (S15). Specifically, in the second period from t1 seconds before the desired wake-up time to the desired wake-up time, in order to wake up the user, the wake-up time setting unit 90 lights at least the first lighting fixture 71 so that the maximum value of the bed surface illuminance in the head region R1a becomes 100 lx or more, preferably 700 lx or more, and gradually increases the light amount of the first lighting fixture 71. Since the light emitted by the first lighting fixture 71 is directly irradiated onto the user's head, the bed surface in the head region R1a becomes brighter.

[0109] In this way, by dimming the bed surface in the head region R1a so that the user's head is not directly irradiated with light in the first period, and brightening it so that the user's head is directly irradiated with light in the next second period, the user gets used to the light. For this reason, the user can wake up at the desired wake-up time with little discomfort.

[0110] <Function and Effect> Next, the function and effect of the rest room 1 in the present embodiment will be described.

[0111] As described above, the lighting system 3 of the present embodiment includes a bed 30 on which the user sleeps, a first lighting fixture 71, a second lighting fixture 72, and a light shielding portion 11f3. Further, at least one of the first lighting fixture 71 and the second lighting fixture 72 has a dimming function for changing the light amount. Also, the distance between the first lighting fixture 71 and the head region R1a, which is the region where the head is placed when the user goes to bed on the bed 30, is 1.5 m or less. Further, the second lighting fixture 72 is installed on the foot side when the user goes to bed on the bed 30. And the light shielding portion 11f3 is disposed between the second lighting fixture 72 and the head region R1a.

[0112] According to this, even when the second lighting fixture 72 emits light, since it is blocked by the light-shielding portion 11f3, it is possible to suppress the light emitted by the second lighting fixture 72 from being directly irradiated onto the head region R1a. That is, it becomes difficult for the light emitted by the second lighting fixture 72 to be directly irradiated onto the head of the user who goes to bed on the bed 30. As a result, the light of the second lighting fixture 72 becomes indirect lighting in which it is suppressed from being directly irradiated onto the user's eyes, so that the user can suppress the discomfort when getting up.

[0113] Also, for example, after the second lighting fixture 72 is turned on, when the first lighting fixture 71 is turned on, the head region R1a is illuminated, so that the first lighting fixture 71 can irradiate the user with bright light.

[0114] Therefore, in this lighting system 3, it is possible to suppress the discomfort of the user when getting up while maintaining a high arousal support effect.

[0115] Further, the lighting system 3 of the present embodiment further includes a wake-up time setting unit 90. When the wake-up time setting unit 90 receives an input of a desired wake-up time, it changes the light amount of at least one of the first lighting fixture 71 and the second lighting fixture 72 from t seconds before the desired wake-up time, thereby changing the bed surface illuminance, which is the illuminance of the surface of the bed 30 in the head region R1a, over time.

[0116] According to this, the bed surface illuminance in the head region R1a gradually changes from t seconds before the desired wake-up time. For example, since the head of the user who goes to bed on the bed 30 gradually becomes brighter, the user can wake up without feeling discomfort when getting up.

[0117] Further, the lighting system 3 of the present embodiment has, in a first section from t seconds before the desired wake-up time to t1 seconds before the desired wake-up time when more time has elapsed than t seconds before, the time average value of the bed surface illuminance in the head region R1a is less than 100 lx. And in a second section from t1 seconds to the desired wake-up time, the maximum value of the bed surface illuminance in the head region R1a is 100 lx or more.

[0118] According to this, by setting the bed surface illuminance in the head region R1a to less than 100 lx, in the first section, it is possible to prevent the user from being woken up by the light from the first lighting fixture 71 and the second lighting fixture 72. Also, in the second section after the first section, by setting the bed surface illuminance to 100 lx or more, the user can be woken up. In this way, in the first section, the head region R1a is slightly illuminated from t seconds before the desired wake-up time, and in the second section, the head region R1a is brightly illuminated from t1 seconds before the desired wake-up time, so that the bed surface illuminance of the head region R1a can be gradually increased. Therefore, with this lighting system 3, it is possible to further suppress the discomfort of the user at the time of waking up.

[0119] Also, in the lighting system 3 of the present embodiment, in the first section, the first lighting fixture 71 is turned off.

[0120] According to this, in the first section, since the first lighting fixture 71 is not lit, light is not directly irradiated onto the head of the user sleeping in the bed 30. Therefore, in the first section, since it is difficult to wake up the user, it is difficult to give discomfort to the user.

[0121] Also, in the lighting system 3 of the present embodiment, in the first section, when the second lighting fixture 72 is lit, the maximum value of the bed surface illuminance in the head region R1a is 1 lx or more.

[0122] For example, when a user is directly irradiated with light during sleep, the user will feel discomfort due to a sudden change in brightness.

[0123] However, according to the present embodiment, in the first section, it is possible to preliminarily brighten the entire space to a certain extent by indirect lighting so that light is not directly irradiated onto the head of the user. Therefore, in the second section, even when the head region R1a is gradually brightened while directly irradiating light onto the head of the user, since the user is accustomed to the light, it is difficult to feel a sudden change in brightness and it is difficult to feel discomfort.

[0124] Further, in the lighting system 3 of the present embodiment, in the second section, when only the first lighting fixture 71 is lit, the temporal maximum value of the bed surface illuminance in the head region R1a is 100 lx or more.

[0125] For example, in the second section, if the first lighting fixture 71 is not lit, the effect of awakening the sleeping user may be insufficient.

[0126] However, according to the present embodiment, by lighting the first lighting fixture 71 in the second section, it is possible to ensure that the bed surface illuminance in the head region R1a is 100 lx or more. Therefore, in the lighting system 3, the user can be awakened.

[0127] Further, in the lighting system 3 of the present embodiment, in the second section, the temporal maximum value of the bed surface illuminance in the head region R1a is 700 lx or more.

[0128] According to this, it is possible to ensure that the bed surface illuminance in the head region R1a is 700 lx or more in the second section. Therefore, in the lighting system 3, the user can be awakened more reliably. In particular, in the second section, by setting the bed surface illuminance to 700 lx or more at a time close to the desired wake-up time, the awakening effect on the user can be enhanced.

[0129] Further, in the lighting system 3 of the present embodiment, the time during which the bed surface illuminance in the head region R1a is 700 lx or more ranges from approximately 10 seconds to 60 seconds.

[0130] For example, if the irradiation time during which the bed surface illuminance in the head region R1a becomes 700 lx or more is short, the effect of awakening the user is reduced. On the other hand, if the irradiation time is long, the user feels discomfort due to glare.

[0131] However, according to the present embodiment, in the second section, by irradiating light with a bed surface illuminance of 700 lx or more in the head region R1a for 10 seconds or more, the effect of awakening the user can be ensured. Further, in the second section, by irradiating light with a bed surface illuminance of 700 lx or more in the head region R1a for a maximum of 60 seconds, the discomfort of the user can be suppressed.

[0132] Further, the lighting system 3 of the present embodiment includes at least one of the sound device 61, the blower 62, and the aromatherapy device 63, a control device 60 that controls at least one of the sound device 61, the blower 62, and the aromatherapy device 63, and an operation device 40 that operates at least one of the sound device 61, the blower 62, and the aromatherapy device 63.

[0133] According to this, since at least one of the sound device 61, the blower 62, and the aromatherapy device 63 can be controlled, a comfortable dozing environment can be provided for the user.

[0134] Further, the rest room 1 of the present embodiment further includes one or more wall portions 11f arranged around the bed 30, a ceiling 13, and a lighting system 3.

[0135] According to this, by combining the booth (room 10) having the wall portion 11f and the ceiling 13 with the lighting system 3, the bed surface illuminance, particularly the bed surface illuminance in the head region R1a, can be easily set to a desired illuminance.

[0136] Further, in the rest room 1 of the present embodiment, the outer dimensions of the rest room 1 are 1100 mm or less × 2100 mm or less × 1950 mm or less. And the outer dimensions of the rest room 1 have a lower limit value of 600 mm or more × 1900 mm or more × 1000 mm or more.

[0137] According to this, if the rest room 1 has these outer dimensions, it is of a size that can be placed in an elevator, so it becomes easy to carry the rest room 1 in and out.

[0138] In addition, it is possible to secure a user's usage space in the indoor space R and suppress the enlargement of the rest room 1 to such an extent that it does not give the user a feeling of oppression. Specifically, the rest room 1 is set to be about 50 cm or more, which is the shoulder width of a person, further set so that a person with a height of 190 cm can lie down, and further set to be about 90 cm or more, which is the sitting height of a person. For this reason, a space where a person can lie on their back and sleep can be secured.

[0139] In addition, the rest room 1 of the present embodiment further includes a moving part.

[0140] According to this, a portable rest room 1 that can be freely moved can be provided.

Note that at least one of the first lighting fixture and the second lighting fixture may have a color adjustment function for changing the light color.

[0145] In addition, the control device, the wake-up time setting unit, etc. included in the lighting system and the rest room according to the above embodiment are typically realized as an LSI which is an integrated circuit. These may be individually integrated into one chip, or may be integrated into one chip so as to include part or all of them.

[0146] In addition, the integration into an integrated circuit is not limited to an LSI, and it may be realized by a dedicated circuit or a general-purpose processor. An FPGA (Field Programmable Gate Array) that can be programmed after manufacturing the LSI, or a reconfigurable processor that can reconfigure the connection and setting of circuit cells inside the LSI may be used.

[0147] Note that in each of the above embodiments, each component may be configured by dedicated hardware, or may be realized by executing a software program suitable for each component. Each component may be realized by a program execution unit such as a CPU or a processor reading and executing a software program recorded in a storage medium such as a hard disk or a semiconductor memory.

[0148] In addition, all the numbers used above are for exemplification to specifically explain the present disclosure, and the embodiments of the present disclosure are not limited to the exemplified numbers.

[0149] Also, the division of functional blocks in the block diagram is an example, and a plurality of functional blocks may be realized as one functional block, one functional block may be divided into a plurality, or some functions may be transferred to other functional blocks. Further, the functions of a plurality of functional blocks having similar functions may be processed by a single piece of hardware or software in parallel or in time division.

[0150] Also, the order in which each step in the flowchart is executed is for illustration purposes to specifically describe the present disclosure, and may be an order other than the above. Also, some of the above steps may be executed simultaneously (in parallel) with other steps.

[0151] Note that forms obtained by applying various modifications that those skilled in the art can conceive to each of the above embodiments, and forms realized by arbitrarily combining the components and functions in each embodiment without departing from the spirit of the present disclosure are also included in the present disclosure.
