(Embodiment)
<Configuration: Rest Room 1>
First, the configuration of the rest room 1 in this embodiment will be described.

Figure 1 is a perspective view showing the exterior of a rest room 1 according to an embodiment. Figure 2 is a perspective view showing the exterior of the rest room 1 with the exterior walls removed. In Figure 2, the wall portion 11f is not shown, except for the first wall portion 11f1 and the second wall portion 11f2.

As shown in Figures 1 and 2, the rest room 1 forms an interior space R that houses a bed 30 for users to take a nap, sleep, or rest. By taking a nap, sleep, or rest in the interior space R, users can reduce drowsiness and relieve fatigue. In other words, users can take a nap, sleep, or rest in the rest room 1. When a user starts using the rest room 1, the user inputs an instruction into the operating device 40 to start controlling the lighting system 3.

In rest room 1, it is possible to illuminate the interior space R. For example, when a user uses rest room 1 as a nap room, when the usage time is set, lighting is provided to help the user fall asleep, to help the user take a nap, and to wake up a user who is napping. Also, when a user uses rest room 1 as a nap room, it is possible to illuminate the interior space R.

In addition, in the rest room 1, the air quality of the indoor space R can be adjusted by taking in air from the outside space. Air quality refers to the temperature, humidity, amount of fragrance components, etc. of the air in the indoor space R.

The break room 1 is also equipped with casters 12. This allows the break room 1 to move freely by rotating the wheels of the casters 12. Furthermore, the break room 1 can be restricted from moving by locking the casters 12, which stops the wheels from rotating.

The external configuration of rest room 1 is explained below using Figures 2 to 3G.

Figure 3A is a front view showing the break room 1 according to the embodiment with the door 18 closed. Figure 3B is a front view showing the break room 1 according to the embodiment with the door 18 open. Figure 3C is a rear view showing the break room 1 according to the embodiment. Figure 3D is a right side view showing the break room 1 according to the embodiment. Figure 3E is a left side view showing the break room 1 according to the embodiment. Figure 3F is a plan view showing the break room 1 according to the embodiment. Figure 3G is a bottom view showing the break room 1 according to the embodiment.

The break room 1 is sized to fit on an elevator. Specifically, the external dimensions of the break room 1, i.e., the length (width) of the break room 1 along the Y-axis direction x the length (height) of the break room 1 along the X-axis direction x the length (height) of the break room 1 along the Z-axis direction, are 1100 mm or less x 2200 mm or less x 2000 mm or less.

Rest Room 1 is sized to allow a user to lie down in a normal standing position. Specifically, the minimum values of the exterior dimensions of Room 10, i.e., the length along the Y-axis of Rest Room 1 (width) × the length along the X-axis of Rest Room 1 × the length along the Z-axis of Rest Room 1 (height), are 600 mm or more × 1900 mm or more × 1000 mm or more. In other words, by setting the minimum width of Rest Room 1 to 600 mm or more, it can be set to a user's shoulder width of approximately 50 cm or more. By setting the minimum length of Rest Room 1 to 1900 mm or more, it can be set to allow a user with a height of 190 cm to lie down. By setting the minimum height of Rest Room 1 to 1000 mm or more, it can be set to a user's sitting height of approximately 90 cm or more.

The specific configuration of rest room 1 is explained below using Figures 2 to 4.

Figure 4 is a block diagram showing the rest room 1 according to the embodiment.

As shown in Figures 2 and 4, the break room 1 includes a room 10, a duct 20, and a lighting system 3.

[Room 10]
As shown in Figures 2, 3A, and 3B, room 10 is provided with a doorway 19 through which users enter and exit. In this embodiment, doorway 19 is located on the negative Y-axis side of room 10 and in the center of room 10 in the X-axis direction. Door 18 is provided at doorway 19, allowing doorway 19 to be opened and closed. Door 18 is a sliding door. Therefore, door 18 is opened by sliding it in the positive X-axis direction, and closed by sliding it in the negative X-axis direction.

The room 10 also forms an interior space R where the user sleeps. Because a long bed 30 is placed in the room 10, the interior space R is long along the X-axis direction according to the size of the bed 30.

As shown in Figures 2 and 4, room 10 is a rectangular parallelepiped housing sized to allow a user to sleep. Room 10 houses bed 30, duct 20, operating device 40, first lighting fixture 71, second lighting fixture 72, light distribution control unit 73, control device 60, acoustic device 61, fans 62 and 64, aroma diffuser 63, and power supply unit 80. It is sufficient that at least one of acoustic device 61, fans 62 and 64, and aroma diffuser 63 be installed in room 10.

The configuration of room 10 will now be explained in detail using Figures 3H to 3L and Figure 5.

Figure 3H is a cross-sectional view of the rest room 1 taken along line H-H in Figure 3F. Figure 3I is a cross-sectional view of the rest room 1 taken along line I-I in Figure 3A according to an embodiment of the present invention. Figure 3J is a cross-sectional view of the rest room 1 taken along line J-J in Figure 3A. Figure 3K is a cross-sectional view of the rest room 1 taken along line K-K in Figure 3F according to an embodiment of the present invention. Figure 3L is a cross-sectional view of the rest room 1 taken along line L-L in Figure 3A according to an embodiment of the present invention. Figure 3M is a cross-sectional view of the rest room 1 taken along line M-M in Figure 3A according to an embodiment of the present invention. Figure 3N is a cross-sectional view of the rest room 1 taken along line N-N in Figure 3A according to an embodiment of the present invention. Figure 5 is a diagram showing the interior space R of the rest room 1 according to an embodiment of the present invention.

As shown in Figures 3H to 3L and Figure 5, when the interior space R of the room 10 is viewed from above along the negative Z-axis, the interior space R includes a first space R1 for the user to sleep in, a second space R2 between the bed 30 and the long side of the room 10 on the doorway 19 side, and a third space R3 between the bed 30 and the long side of the room 10 on the doorway 19 side, which is located at the feet of the user when sleeping in the bed 30. In Figure 5, the first space R1 is shown with dotted hatching, the second space R2 is shown with diagonal hatching, and the third space R3 is shown with grid hatching.

The second space R2 and the third space R3 are located on the negative Y-axis side relative to the first space R1. The third space R3 is located on the negative X-axis side relative to the second space R2, and is located at the feet of the user when sleeping in the bed 30. The bed 30 and other items are located in the first space R1, the operating device 40 and the floorboard 11b of the room 10 are located in the second space R2, and the fan 62, aroma diffuser 63, second lighting fixture 72, and power supply unit 80 (see Figure 4) are located in the third space R3.

As shown in FIG. 2, the room 10 includes multiple frameworks 11, multiple casters 12, multiple wall sections 11f, a ceiling 13, and a light distribution control unit 73.

The multiple frameworks 11 each include a frame-shaped base 11a, floorboards 11b, multiple pillars 11c, and an upper frame 11d.

The base 11a is a rectangular frame body, and is positioned vertically below the room 10 (in the negative Z-axis direction) so that it is approximately parallel to the XY plane. A number of casters 12 are provided on the end face of the base 11a on the negative Z-axis side, with one-to-one correspondence at least with each corner. Therefore, the base 11a is positioned so that it faces the ground via the casters 12.

The casters 12 can rotate when the room 10 moves relative to the ground, or can be locked to prevent the wheels from rotating. The casters 12 are an example of a moving part.

Multiple joists 11a1 are connected to the base 11a. A floorboard 11b is provided on top of the base 11a and the multiple joists 11a1. The floorboard 11b is elongated along the X-axis direction. The floorboard 11b is located between the bed 30 and the entrance/exit 19 of the room 10, and is disposed on top of the base 11a and the multiple joists 11a1 in the second space R2.

The multiple pillars 11c are elongated and extend along the Z-axis direction from each corner of the base 11a, supporting the upper frame 11d.

The multiple pillars 11c include a first pillar 11c1, a second pillar 11c2, and a third pillar 11c3. The first pillar 11c1 is located at a corner of the base 11a that is the end facing the negative X-axis direction and the end facing the negative Y-axis direction. The second pillar 11c2 is adjacent to the first pillar 11c1 and is located further in the positive X-axis direction than the first pillar 11c1. The third pillar 11c3 is adjacent to the first pillar 11c1 and is located further in the positive Y-axis direction than the first pillar 11c1. A third space R3 is formed by the first pillar 11c1, the second pillar 11c2, the third pillar 11c3, and the wall portion 11f connected to these pillars.

The multiple walls 11f are partitions that define the interior space R. Some of the multiple walls 11f are located between two adjacent columns 11c out of the multiple columns 11c.

One or more wall portions 11f are arranged around the periphery of the bed 30, for example, at least one of the front, back, left, and right sides of the bed 30.

The multiple wall portions 11f include a first wall portion 11f1, a second wall portion 11f2, a third wall portion 11f3, and a fourth wall portion 11f4. The first wall portion 11f1, the second wall portion 11f2, the third wall portion 11f3, and the fourth wall portion 11f4 are arranged around the blower 62, the aroma diffuser 63, etc., and form a third space R3.

Specifically, the first wall portion 11f1 is disposed between the first pillar 11c1 and the second pillar 11c2. The second wall portion 11f2 is disposed between the first pillar 11c1 and the third pillar 11c3. The third wall portion 11f3 is disposed between the second lighting fixture 72 and the head region R1a, at the boundary between the first space R1 and the third space R3, on the foot side when the user is sleeping in the bed 30. Therefore, the third wall portion 11f3 can block light emitted from the second lighting fixture 72 so that it does not directly irradiate the user's head when the user is sleeping in the bed 30. Furthermore, as shown in FIG. 3L, the third wall portion 11f3 is formed with an air outlet 16 through which air is introduced via the fan 62 and the aroma diffuser 63. The fourth wall portion 11f4 is located between the third wall portion 11f3 and the second pillar 11c2, facing the first wall portion 11f1. The fourth wall portion 11f4 has a light source wall surface 11g4 on which the second lighting fixture 72 is mounted. The fourth wall portion 11f4 is located between the second wall portion 11f2 and the third wall portion 11f3 so that the light source wall surface 11g4 is perpendicular to the first side wall surface 11g1 of the fifth wall portion 11f5. The second lighting fixture 72 is disposed adjacent to the light source wall surface 11g4. The first wall portion 11f1, the second wall portion 11f2, the third wall portion 11f3, and the fourth wall portion 11f4 are examples of walls 11f.

Furthermore, the multiple pillars 11c include a fourth pillar 11c4, a fifth pillar 11c5, and a sixth pillar 11c6. The first pillar 11c1, the fourth pillar 11c4, the fifth pillar 11c5, and the sixth pillar 11c6 are arranged at the four corners of the room 10. The first pillar 11c1, the fourth pillar 11c4, the fifth pillar 11c5, and the sixth pillar 11c6, together with the multiple wall portions 11f, form an interior space R.

The fourth pillar 11c4 is located at a corner of the base 11a, which is the end facing the negative X-axis and the end facing the positive Y-axis. The fifth pillar 11c5 is located at a corner of the base 11a, which is the end facing the positive X-axis and the end facing the positive Y-axis. The sixth pillar 11c6 is located at a corner of the base 11a, which is the end facing the positive X-axis and the end facing the negative Y-axis.

As shown in Figures 3H to 3L and 5, the multiple wall portions 11f further include a fifth wall portion 11f5, a sixth wall portion 11f6, and a seventh wall portion 11f7.

The fifth wall portion 11f5 is perpendicular to the light source wall surface 11g4 of the fourth wall portion 11f4 and has a first side wall surface 11g1 that is a surface along the optical axis of the second lighting fixture 72. The fifth wall portion 11f5 is disposed between the third pillar 11c3 and the fourth pillar 11c4 so that the first side wall surface 11g1 is parallel to the Y-Z plane. The first side wall surface 11g1 is an example of a side wall surface.

The sixth wall portion 11f6 is perpendicular to the first side wall surface 11g1 of the fifth wall portion 11f5 and has a second side wall surface 11g2 facing the light source wall surface 11g4. Light emitted by the second lighting fixture 72 is irradiated onto the second side wall surface 11g2. The first lighting fixture 71, the second lighting fixture 72, the acoustic device 61, the fans 62, 64, and the aroma diffuser 63 are not arranged on the second side wall surface 11g2. The sixth wall portion 11f6 is arranged between the fourth pillar 11c4 and the fifth pillar 11c5 so that the second side wall surface 11g2 is parallel to the X-Z plane. The second side wall surface 11g2 is included in the irradiated wall surface.

The seventh wall portion 11f7 is perpendicular to the light source wall surface 11g4 of the sixth wall portion 11f6 and has a head-side wall surface facing the first side wall surface 11g1. The seventh wall portion 11f7 is disposed between the fifth pillar 11c5 and the sixth pillar 11c6 so that the head-side wall surface is parallel to the Y-Z plane.

The upper frame 11d is a rectangular frame body that is positioned vertically above the room 10 (in the positive direction of the Z axis) so that it is approximately parallel to the XY plane. The upper frame 11d corresponds to the base 11a and is supported by multiple pillars 11c. In this embodiment, two upper frames 11d are provided. A duct 20 is positioned between the two upper frames 11d.

As shown in Figures 3M and 3N, the upper frame 11d is provided with a ceiling 13. The ceiling 13 has a ceiling surface 13a that is perpendicular to the light source wall surface 11g4 and the first side wall surface 11g1. The ceiling surface 13a is included in the irradiation wall surface. The ceiling 13 is provided with a duct 20 and an intake port 20b that serves as the opening of the duct 20. A blower 64 is provided in the flow path of the duct 20, which guides air drawn in from the intake port 20b to the air outlet 20a of the duct 20.

Air outlet 20a blows out air that has been sucked in through inlet 20b and passed through duct 20. Inlet 20b is located on the ceiling 13 on the side of the user's lower body when sleeping in bed 30. By positioning inlet 20b away from the user's head, the suction sound can be made inaudible to the user.

The air inlet 20b is located on the ceiling 13. This allows the air inlet 20b to draw in air from inside the room 10.

As shown in Figures 3I and 3K, the light distribution control unit 73 is disposed on the side in the direction of emission of light from the second lighting fixture 72. Specifically, the light distribution control unit 73 is disposed between the second wall portion 11f2 and the fourth wall portion 11f4 so as to cover the opening 11h.

The light distribution control unit 73 has a light blocking plate 74 and a diffusion plate 75.

The light-shielding plate 74 is a rectangular plate in a plan view. The light-shielding plate 74 may be made of any material, including resin, metal such as iron or aluminum, or wood.

The light-shielding plate 74 is disposed between the second wall 11f2 and the fourth wall 11f4 so as to cover a portion of the opening 11h. In other words, the light-shielding plate 74 is disposed on the side in the direction of emission of light from the second lighting fixture 72, between the center of the first side wall 11g1 and the second lighting fixture 72. Specifically, the light-shielding plate 74 is disposed between the second wall 11f2 and the fourth wall 11f4 so as to face the second lighting fixture 72 and be oriented approximately parallel to the X-Z plane, and perpendicular to the optical axis of the second lighting fixture 72. Here, the center of the first side wall 11g1 refers to the center of the first side wall 11g1 in the Y-axis direction.

When viewed along the Z-axis direction, the light-shielding plate 74 covers at least one-quarter of the distance between the second wall portion 11f2 and the optical axis of the light source. In this embodiment, the light-shielding plate 74 is positioned in close contact with the second wall portion 11f2 so that no gap is formed between the light-shielding plate 74 and the second wall portion 11f2.

Furthermore, a slit 74a is formed in the light-shielding plate 74 on the side opposite the first side wall surface 11g1 from the optical axis of the second lighting fixture 72. In other words, the slit 74a is formed on the light-shielding plate 74 on the positive X-axis side from the Y-Z plane containing the optical axis of the second lighting fixture 72. In other words, the slit 74a is not formed on the negative X-axis side from the Y-Z plane containing the optical axis of the second lighting fixture 72, i.e., on the second wall portion 11f2 side.

For this reason, the light blocking plate 74 is positioned so that the light emitted by the second lighting fixture 72 does not directly illuminate the center of the first side wall surface 11g1, thereby preventing the center of the first side wall surface 11g1 from becoming too bright.

One side edge of the light-shielding plate 74 may be in close contact with the first wall portion 11f1 so that no gap is formed between the light-shielding plate 74 and the first wall portion 11f1. A gap may also be formed between the light-shielding plate 74 and the third wall portion 11f3. In other words, a gap through which light emitted by the second lighting device 72 can pass may be formed between the light-shielding plate 74 and the third wall portion 11f3. In this case, the light-shielding plate 74 does not need to have a slit 74a formed therein. In other words, the slit 74a is not an essential component of the light-shielding plate 74.

As another example, a light-shielding sheet or light-shielding tape may be attached to the diffusion plate 75, causing it to function like the light-shielding plate 74. Also, a light-shielding sheet or light-shielding tape may be attached to the light-emitting surface of the second lighting fixture 72, causing it to function like the light-shielding plate 74.

The diffuser plate 75 is a rectangular plate in a plan view. The diffuser plate 75 diffuses (scatters) the light emitted from the second lighting device 72. The diffuser plate 75 is a diffusing member made of, for example, a translucent resin material such as acrylic resin or polycarbonate, or glass. The diffuser plate 75 may also be a diffusing member that can transmit and scatter part of the light by roughening the surface or dispersing a light diffusing material inside the base material.

The diffuser plate 75 is positioned closer to the light output direction of the second lighting fixture 72 than the light-shielding plate 74. In other words, the diffuser plate 75 is positioned so as to face both the light-shielding plate 74 and the second side wall surface 11g2. Therefore, the diffuser plate 75 diffuses light that has passed through the light-shielding plate 74.

In this type of light distribution control unit 73, when the second lighting fixture 72 emits light, some of the light is blocked by the light blocking plate 74. The remaining light passes through the slits 74a in the light blocking plate 74. The light that passes through the slits 74a in the light blocking plate 74 is incident on the diffuser plate 75. The light that enters the diffuser plate 75 is diffused as it passes through the diffuser plate 75, and is emitted from the surface on the second side wall surface 11g2 side. Therefore, the light that exits from the diffuser plate 75 is irradiated onto the first side wall surface 11g1, the second side wall surface 11g2, and the ceiling surface 13a.

Furthermore, the diffusion plate 75 and the light blocking plate 74 have a length of 85 mm along the X-axis direction in a plan view, and a length (height) of 685 mm along the Z-axis direction. Therefore, the size of the opening 11h of the housing body 14 for arranging the diffusion plate 75 and the light blocking plate 74 is also of a similar size.

[Lighting System 3]
2 and 4 , when a user inputs the usage time via the operation device 40, the lighting system 3 illuminates the surface of the bed 30 on which the user will sleep, and performs a lighting mode that puts the user to sleep at the start of the usage time, a lighting mode that puts the user to take a nap, a lighting mode that wakes up the napping user at the end of the usage time, etc. In other words, by executing each lighting mode, the lighting system 3 can provide a lighting environment that supports the user's falling asleep and the user's awakening after falling asleep.

The lighting system 3 includes at least a second lighting fixture 72 and a control device 60 for changing the light output of at least one of the first lighting fixture 71 and the second lighting fixture 72. In this embodiment, the lighting system 3 includes the first lighting fixture 71, the second lighting fixture 72, a bed 30, an operating device 40, the control device 60, an acoustic device 61, fans 62 and 64, an aroma diffuser 63, and a power supply unit 80. Note that the lighting system 3 may include at least one of the acoustic device 61, fans 62 and 64, and aroma diffuser 63, and does not necessarily include all of these devices.

[First lighting fixture 71 and second lighting fixture 72]
The first lighting fixture 71 and the second lighting fixture 72 can illuminate the interior space R. The first lighting fixture 71 is a lighting device for waking up, and the second lighting fixture 72 is a lighting device for falling asleep. The first lighting fixture 71 and the second lighting fixture 72 are included in the light sources.

The first lighting fixture 71 and the second lighting fixture 72 also have a dimming function that changes the light intensity and a dimming function that changes the color temperature. Therefore, the first lighting fixture 71 and the second lighting fixture 72 can change the light output or color temperature by receiving lighting control instructions from the control device 60 or direct instructions from the operating device 40. For example, the first lighting fixture 71 and the second lighting fixture 72 perform dimming control and color adjustment control by receiving lighting control instructions from the control device 60 based on the usage time. This allows the first lighting fixture 71 and the second lighting fixture 72 to change the luminance (brightness) and color temperature during usage time.

The first lighting fixture 71 is positioned vertically above the upper body of the user when sleeping in bed 30. Specifically, the first lighting fixture 71 is mounted on the ceiling 13. The first lighting fixture 71 is also positioned so as to be embedded in the ceiling 13. The first lighting fixture 71 may be mounted within the interior space R.

The second lighting fixture 72 is installed at the foot of the user when the user is sleeping in bed 30. Specifically, as shown in Figures 3I, 3K, and 5, the second lighting fixture 72 is placed in the third space R3 while being housed in a housing 14 connected to the second wall portion 11f2. The second lighting fixture 72 is housed in the housing 14. The housing 14 is a rectangular housing that is elongated along the Z-axis direction so that it can house the second lighting fixture 72, which is elongated in the Z-axis direction. The housing 14 has an opening 11h that opens on the positive side of the Y-axis. Therefore, when the second lighting fixture 72, which is supported by the housing 14, emits light toward the opening 11h, the opening 11h allows this light to pass through. In other words, when the second lighting fixture 72 is turned on, the light emitted by the second lighting fixture 72 is emitted through the opening 11h, is further reflected by the wall 11f of the room 10 and the bed 30, and is then irradiated onto the head region R1a.

In this embodiment, the specifications of the second lighting fixture 72 are as follows: The luminous flux of the second lighting fixture 72 is 1250 lm. The external dimensions of the second lighting fixture 72, width x length x height, are 63 mm x 597 mm x 54 mm. The dimming range of the second lighting fixture 72 is 5 to 100%. The color tuning range of the second lighting fixture 72 is from daylight white to warm white, for example, approximately 5000 to 2700 K. The first lighting fixture 71 may have the same specifications as the second lighting fixture 72.

In addition, only the first lighting fixture 71 or the second lighting fixture 72 may be installed in the rest room 1.

The external dimensions of this second lighting fixture 72, i.e., length along the Y axis (width) × length along the X axis × length along the Z axis (height), are 53.5 mm × 63 mm × 685 mm. The external dimensions of the housing 14 are 57 mm × 97 mm × 680 mm.

[Bed 30]
2 and 4, the bed 30 allows a user to sit and sleep. The bed 30 is elongated along the X-axis direction in the first space R1. The bed 30 in this embodiment is supported by a plurality of pillars 11c, but may also be placed on a base 11a and a plurality of joists 11a1.

The bed 30 is set so that the user's head is located on the positive side of the X axis of the bed 30 and the user's feet are located on the negative side of the X axis of the bed 30.

The bed 30 of this embodiment also includes a chair that transforms to function as a bed 30. Specifically, the bed 30 may have a seat on which a user sits, a footrest rotatably connected to the seat, a backrest rotatably connected to the seat, and a headrest connected to the backrest. In this case, the chair may function as a bed 30 with the footrest, seat, backrest, and headrest arranged in a straight line. The bed 30 of this embodiment may also be tiltable and may transform like a chair. In the case of a chair, the illuminance on the surface of the backrest and the illuminance on the surface of the headrest when the user leans their back against the backrest and places their head on the headrest correspond to the bed surface illuminance. Here, the bed surface illuminance is the illuminance on the surface of the bed 30 when at least one of the first lighting fixture 71 and the second lighting fixture 72 is turned on.

[Operating device 40]
The operating device 40 is disposed on the positive side of the X-axis in the second space R2. In other words, when the user is lying down in the bed 30, the operating device 40 is disposed near the head. The operating device 40 may be disposed in one or more of the first space R1, the second space R2, and the third space R3. In other words, multiple operating devices 40 may be provided in the rest room 1.

The operating device 40 also allows the user to individually operate each of the first lighting fixture 71, second lighting fixture 72, sound device 61, fans 62 and 64, and aroma diffuser 63. In other words, the operating device 40 outputs instructions operated by the user to the control device 60, which then activates or deactivates each of the first lighting fixture 71, second lighting fixture 72, sound device 61, fans 62 and 64, and aroma diffuser 63. Note that the operating device 40 may only be capable of operating at least one of the first lighting fixture 71, second lighting fixture 72, sound device 61, fans 62 and 64, and aroma diffuser 63.

The operating device 40 can also accept input from the user. Specifically, when the user inputs the usage time into the operating device 40, the operating device 40 outputs usage time information, which is information indicating the usage time input by the user, to the control device 60.

The operating device 40 is also located on the opposite side of the bed 30 in the longitudinal direction from the side on which the second lighting device 72 is located. In other words, the operating device 40 is located on the head side when the user is lying down in the bed 30. This allows the user to operate the operating device 40 while lying down.

[Control device 60]
Control device 60 can control each of first lighting device 71, second lighting device 72, acoustic device 61, fans 62 and 64, and aroma diffuser 63 in response to instructions from operating device 40. Note that control device 60 may only control at least one of first lighting device 71, second lighting device 72, acoustic device 61, fans 62 and 64, and aroma diffuser 63.

First, we will explain how the control device 60 controls the first lighting fixture 71 and the second lighting fixture 72.

The control device 60 receives from the operating device 40 an instruction to start controlling the first lighting fixture 71 and the second lighting fixture 72 from the usage time indicated in the usage time information. The control device 60 generates a lighting control instruction based on the usage time information indicated in the received instruction, and outputs the generated lighting control instruction to the first lighting fixture 71 and the second lighting fixture 72. Specifically, the control device 60 controls the first lighting fixture 71 and the second lighting fixture 72 by outputting a lighting control instruction to the first lighting fixture 71 and the second lighting fixture 72 according to the length of the usage time indicated in the received usage time information.

Next, we will explain how the control device 60 controls the acoustic device 61, fans 62 and 64, and aroma diffuser 63.

For example, when a user operates the operating device 40 to input an instruction, the control device 60 instructs the audio device 61 to play music in accordance with the instruction received from the operating device 40. As a result, the audio device 61 plays music, and the played music is output into the indoor space R. Furthermore, by receiving instructions from the operating 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.

Furthermore, when the user operates the operating device 40 to input an instruction to change the fans 62, 64 from an OFF state to an ON state, the control device 60 turns on the power to the fans 62, 64 in accordance with the instruction received from the operating device 40. As a result, the fan 62 is driven, and air from the external space is taken in and exhausted into the indoor space R of the room 10. Furthermore, the control device 60 can control the output of the fans 62, 64, i.e., the rotation speed of the fans in the fans 62, 64, by receiving instructions from the operating device 40.

Furthermore, when the user operates the operating device 40 to input an instruction to change the aroma diffuser 63 from an OFF state to an ON state, the control device 60 turns on the power of the aroma diffuser 63 in accordance with the instruction received from the operating device 40. This drives the aroma diffuser 63, and the aroma freshener in the aroma diffuser 63 is introduced into the air within the room space R. Furthermore, by receiving instructions from the operating device 40, the control device 60 can control the output of the aroma diffuser 63, i.e., the amount of aroma freshener introduced into the room space R.

[Sound device 61, fans 62 and 64, and aroma diffuser 63]
The sound device 61 can provide the user with music that has a sleep-inducing effect or music that has a waking effect by playing music in the room 10. The sound device 61 is housed in the room 10 and is arranged, for example, in the interior space R. The sound device 61 can change the music played in the interior space R and adjust the volume by the user operating the operation device 40.

The blower 62 is disposed in the room 10 and draws in air through an inlet provided in the room 10 and blows out the air from an outlet provided in the indoor space R, thereby generating an airflow within the indoor space R. The blower 64 can also exhaust air within the indoor space R by drawing in air through the inlet 20b provided in the room 10 and blowing out the air from the outlet 20a. The blower 62 is driven to take in air from the outside space, and the blower 64 exhausts it, thereby adjusting the temperature, humidity, etc. of the air in the indoor space R. Although two blowers 62, 64 are illustrated in this embodiment, either one may be used.

As a result, by driving the fans 62 and 64 while they are positioned on the air inlet side, air can be circulated within the room 10. The output of these fans 62 and 64 can be adjusted using the operating device 40.

Furthermore, the fans 62 and 64 are positioned at the feet of the user when sleeping in the bed 30.

The aroma diffuser 63 is placed in the room 10 and can adjust the amount of aroma in the room space R by introducing an aroma into the air blown out from the air outlet. For example, the aroma diffuser 63 can inject an aroma into the air flowing from the air inlet to the air outlet by driving the air blower 62 under the control of the control device 60. In other words, the aroma diffuser 63 is carried by the airflow from the air inlet to the air outlet, and is guided into the room space R. This makes it possible to fill the room space R with a fragrance that the user will enjoy. The output of such an aroma diffuser 63 can be adjusted by the operating device 40.

The aroma diffuser 63 can introduce the aromatic agent into the room space R without driving the air blower 62. In other words, the aroma diffuser 63 can fill the room space R with the aroma of the aromatic agent simply by being placed in the room space R.

Furthermore, the aroma diffuser 63 is placed at the feet of the user when sleeping in the bed 30. Specifically, the aroma diffuser 63 is placed in the flow path of the duct 20 or in the third space R3. In this embodiment, the aroma diffuser 63 is placed downstream of the blower 62 and closer to the ceiling 13 than the blower 62 so as to be away from the user's head.

In this embodiment, the blower 62 and the aroma diffuser 63 are located on the negative Z-axis side (lower side) of the ceiling 13, but this is not limited to this. Only the blower 62 may be located on the negative Z-axis side of the ceiling 13. In this embodiment, the blower 62 and the aroma diffuser 63 are located at the feet of the user when sleeping in the bed 30, but this is not limited to this. Only the blower 62 may be located at the feet of the user when sleeping in the bed 30. In these cases, the aroma diffuser 63 may be located above the ceiling 13.

[Power supply section 80]
Power supply unit 80 controls the light output by supplying power to first lighting device 71 and second lighting device 72, and controls the output by supplying power to acoustic device 61, fans 62 and 64, and aroma diffuser 63. In other words, power supply unit 80 generates drive power for driving first lighting device 71, second lighting device 72, acoustic device 61, fans 62 and 64, and aroma diffuser 63, and supplies this drive power to first lighting device 71, second lighting device 72, acoustic device 61, fans 62 and 64, and aroma diffuser 63, respectively.

[Brightness, Brightness Ratio, Reflectance, and Diffusion Rate of Second Side Wall Surface 11g2 and Ceiling Surface 13a]
When the second lighting device 72 emits light, the brightness of the center of the first side wall surface 11g1 is lower than the brightness at a position on the second side wall surface 11g2 (hereinafter referred to as the first position P1) where the acute angle between the first side wall surface 11g1 and the straight line indicated by the dotted line connecting the center of the first side wall surface 11g1 to the second side wall surface 11g2 is 35°.

Specifically, a light-shielding plate 74 of the light distribution control unit 73 is disposed between the second lighting fixture 72 and the first side wall surface 11g1. The portion of the light-shielding plate 74 located on the line connecting the second lighting fixture 72 and the first side wall surface 11g1 does not have a slit 74a. Meanwhile, the light-shielding plate 74 of the light distribution control unit 73 is disposed between the second lighting fixture 72 and the first position P1 of the second side wall surface 11g2. The portion of the light-shielding plate 74 located on the line connecting the second lighting fixture 72 and the first position P1 of the second side wall surface 11g2 has a slit 74a. Therefore, even if the center of the first side wall surface 11g1 is closer to the second lighting fixture 72 than the second side wall surface 11g2, the brightness at the first position P1 is brighter than the brightness at the center of the first side wall surface 11g1.

The luminance ratios at positions P3, P2, and P1 on the second side wall surface 11g2, where the angles are 80°, 70°, and 35°, are 3% to 24%, 25% to 60%, and 100% to 200%, respectively. In other words, the luminance ratio on the second side wall surface 11g2 decreases as the angle increases from the first position P1 on the second side wall surface 11g2, where the angle is 35°. In other words, the luminance ratio on the second side wall surface 11g2 decreases from position P1 on the second side wall surface 11g2, where the angle is 35°, toward the seventh wall portion 11f7. Furthermore, the luminance ratio also decreases as the angle approaches the first side wall surface 11g1 from position P1 on the second side wall surface 11g2, where the angle is 35°. In other words, the brightness ratio is highest at the first position P1 on the second side wall surface 11g2, where the angle is 35°, and a brightness gradation is achieved in which the brightness becomes darker as you move closer to the seventh wall portion 11f7, using the first position P1 as the reference point. Here, the brightness ratio is the ratio when the brightness at the reference point on the second side wall surface 11g2 is 100%.

At least one of the reflectance and diffusion rates at positions P3, P2, and P1 on the second side wall surface 11g2, where the angles are 80°, 70°, and 35°, is 3% to 24%, 25% to 60%, and 100% to 200%, respectively. In other words, at least one of the reflectance and diffusion rates on the second side wall surface 11g2 decreases as the angle increases from position P1 on the second side wall surface 11g2, where the angle is 35°. In other words, at least one of the reflectance and diffusion rates on the second side wall surface 11g2 decreases from position P1 on the second side wall surface 11g2, where the angle is 35°, toward the seventh wall portion 11f7. Furthermore, at least one of the reflectance and diffusion rate also decreases as the angle approaches the first side wall surface 11g1 from first position P1 on the second side wall surface 11g2, where the angle is 35°. In other words, at the first position P1 on the second side wall surface 11g2, where the angle is 35°, at least one of the reflectance and the diffusion rate is highest.

The above describes the brightness on the second side wall surface 11g2, but the same applies to the ceiling surface 13a. The brightness on the ceiling surface 13a will be explained using Figure 6.

Figure 6 is a diagram showing the positions of the ceiling surface 13a where the angles are 80°, 70°, and 35° in the rest room 1 according to the embodiment. The light distribution control unit 73, the first wall portion 11f1, etc. are omitted from Figure 6. Figure 6 also illustrates an example in which a long second lighting fixture 72 is arranged along the Y-axis direction. The second lighting fixture 72 may be arranged on the edge of the bed 30 at the foot side when the user is sleeping on the bed 30.

In this case, when the second lighting fixture 72 emits light, the brightness at the center of the first side wall surface 11g1 is lower than the brightness at a position on the ceiling surface 13a (hereinafter referred to as the second position Q2) where the acute angle between the first side wall surface 11g1 and the line connecting the center of the first side wall surface 11g1 to the ceiling surface 13a is 35°.

Furthermore, the luminance ratios at second positions Q3, Q2, and Q1 on ceiling surface 13a where the angles are 80°, 70°, and 35° are 3% to 24%, 25% to 60%, and 100% to 200%, respectively. In other words, the luminance ratio on ceiling surface 13a decreases as the angle increases from second position Q1 on ceiling surface 13a where the angle is 35°.

Furthermore, at least one of the reflectance and diffusion rate at the second positions Q3, Q2, and Q1 on the ceiling surface 13a where the angles are 80°, 70°, and 35°, respectively, is 3% to 24%, 25% to 60%, and 100% to 200%, respectively.

<Action and effect>
Next, the effects of the rest room 1 in this embodiment will be described.

As described above, the rest room 1 of this embodiment includes a light source (including a first lighting fixture 71 and a second lighting fixture 72) with dimming capabilities, a light source wall surface 11g4 on which the light source is mounted, a side wall surface (first side wall surface 11g1) that is perpendicular to the light source wall surface 11g4 and extends along the optical axis of the light source, and an irradiation wall surface (at least a second side wall surface 11g2) onto which light emitted from the light source is irradiated. When the light source emits light, the brightness of the center of the side wall surface is lower than the brightness at a position on the irradiation wall (first position P1) where the acute angle between the side wall surface and a line connecting the center of the side wall surface to the irradiation wall surface is 35°.

This makes it possible to reduce glare caused by light irradiated onto the center of the first side wall surface 11g1. Therefore, for example, when a user sleeps on a bed, chair, or other resting device with their feet facing the first side wall surface 11g1 and aligned along the normal direction of the first side wall surface 11g1, the first side wall surface 11g1 does not appear bright from the head side. This makes it possible to reduce glare caused by light irradiated onto the first side wall surface 11g1.

Therefore, this rest room 1 can prevent users from being disturbed while they sleep.

Furthermore, in the rest room 1 of this embodiment, the brightness ratios at positions P3, P2, and P1 on the irradiated wall surface at angles of 80°, 70°, and 35° are 3% to 24%, 25% to 60%, and 100% to 200%, respectively.

This allows the brightness ratio to decrease as the angle on the irradiated wall surface changes from 30° to 70° and then to 80°, creating the illusion of gradually dimmer brightness (creating a brightness gradient). Furthermore, as described above, glare caused by light irradiated onto the center of the first side wall surface 11g1 can be suppressed. In other words, the light irradiated onto the center of the first side wall surface 11g1 is less likely to interfere with the illusion of gradually dimmer brightness on the irradiated wall surface. Therefore, the brightness and darkness of the light irradiated onto the irradiated wall surface can create the illusion that the user has their eyes naturally closed. As a result, an environment that makes it easier for the user to fall asleep can be provided.

Furthermore, in the rest room 1 of this embodiment, at least one of the reflectance and diffusion rate at positions P3, P2, and P1 on the irradiated wall surface where the angles are 80°, 70°, and 35° is 3% to 24%, 25% to 60%, and 100% to 200%, respectively.

This means that simply satisfying at least one of the reflectance and diffusion rates described above on the irradiated wall surface can provide the user with an environment that helps them fall asleep. This allows for the user to freely select the second lighting device 72.

In addition, the rest room 1 of this embodiment further includes a light distribution control unit 73 arranged in the emission direction of the light emitted from the light source.

This reduces the amount of light incident on the first side wall surface 11g1, thereby suppressing the occurrence of glare on the first side wall surface 11g1.

In addition, in the rest room 1 of this embodiment, the light distribution control unit 73 has a light blocking plate 74 arranged on the side in the direction of emission of light emitted from the light source, and a diffusion plate 75 arranged further toward the emission direction than the light blocking plate 74. The light blocking plate 74 is arranged between the center of the side wall surface and the light source.

This allows the diffuser plate 75 to block a portion of the light emitted from the second lighting fixture 72, and also diffuse the light that has passed through the light-blocking plate 74. This reduces the occurrence of glare on the first side wall surface 11g1 and the second side wall surface 11g2 caused by the light emitted from the second lighting fixture 72. This allows the user to feel as if their eyes are naturally closed, due to the brightness and darkness of the light irradiated onto the irradiated wall surface. As a result, an environment that makes it easier for the user to fall asleep can be provided.

In addition, it is no longer necessary to use a material with adjusted reflectivity or diffusion rate for the second side wall surface 11g2. This means that the wall material used for the second side wall surface 11g2 can be freely selected.

In addition, in the rest room 1 of this embodiment, a slit 74a is formed in the light shielding plate 74 on the side opposite the side wall surface from the optical axis of the light source.

As a result, the light shielding plate 74 can block light between the second lighting fixture 72 and the center of the first side wall surface 11g1. Therefore, the light emitted by the second lighting fixture 72 does not directly illuminate the center of the first side wall surface 11g1, preventing the center of the first side wall surface 11g1 from becoming overly bright. Furthermore, the slit 74a is formed on the light shielding plate 74 at a position opposite the first side wall surface 11g1 from the optical axis of the second lighting fixture 72. Therefore, the light emitted by the second lighting fixture 72 is reduced as it passes through the slit 74a, thereby reducing the amount of light irradiated onto the second side wall surface 11g2. As a result, glare caused by the light emitted from the second lighting fixture 72 onto the first side wall surface 11g1 and the second side wall surface 11g2 can be reduced. In this rest room 1, the brightness and darkness of the light irradiated onto the irradiated wall surface can create the illusion that users have their eyes naturally closed.

Furthermore, in the rest room 1 of this embodiment, the light blocking plate 74 covers at least 1/4 of the distance between the side wall surface and the optical axis of the light source.

As a result, the light blocking plate 74 can block at least a portion of the light directed from the second lighting fixture 72 toward the center of the first side wall surface 11g1. This prevents the center of the first side wall surface 11g1 from becoming too bright. As a result, it is possible to reduce the occurrence of glare caused by light emitted from the second lighting fixture 72 onto the first side wall surface 11g1 and the second side wall surface 11g2. In this rest room 1, the brightness and darkness of the light irradiated onto the irradiated wall surface can be used to create the illusion that users have their eyes naturally closed.

Furthermore, in the rest room 1 of this embodiment, the irradiated wall surface includes the light source wall surface 11g4 and the ceiling surface 13a, which is perpendicular to the side wall surface.

As with the second side wall surface 11g2, the ceiling surface 13a is illuminated so that the brightness ratio decreases as the angle increases from 30° to 70° and then to 80°, creating the illusion of gradually dimmer brightness. Therefore, the brightness and darkness of the light irradiated onto the ceiling surface 13a can be used to create the illusion that the user has their eyes naturally closed. As a result, an environment that makes it easier for the user to fall asleep can be provided.

Furthermore, in the rest room 1 of this embodiment, the luminance ratio on the irradiated wall surface and ceiling surface 13a decreases as the angle increases from positions P1 and Q1, where the angle of the irradiated wall surface is 35°.

This allows a brightness gradation to be created on the second side wall surface 11g2 and the ceiling surface 13a. Therefore, by placing the resting device in the rest room 1 so that the position with the lowest brightness corresponds to the position where the user's head will be when sleeping on the resting device, the light shining on the second side wall surface 11g2 and the ceiling surface 13a can be used to give the user the impression that their eyes are naturally closed. As a result, an environment that makes it easier for users to fall asleep can be provided.

In the rest room 1 of this embodiment, the light sources include a first lighting fixture 71 for waking up and a second lighting fixture 72 for falling asleep. The rest room 1 also includes at least one of the first lighting fixture 71, the second lighting fixture 72, the sound device 61, the fans 62 and 64, and the aroma diffuser 63; a control device 60 that controls at least one of the first lighting fixture 71, the second lighting fixture 72, the sound device 61, the fans 62 and 64, and the aroma diffuser 63; and an operating device 40 that operates at least one of the first lighting fixture 71, the second lighting fixture 72, the sound device 61, the fans 62 and 64, and the aroma diffuser 63. The first lighting fixture 71, the second lighting fixture 72, the sound device 61, the fans 62 and 64, and the aroma diffuser 63 are not located on the irradiated wall surface.

This allows for control of at least one of the acoustic device 61, the fans 62 and 64, and the aroma diffuser 63, providing the user with a comfortable sleeping environment.

Furthermore, in this embodiment, the exterior dimensions of the rest room 1 are 1110 mm or less x 2200 mm or less x 2000 mm or less.

This means that if the exterior dimensions of the break room 1 are such that it can be placed on an elevator, it will be easier to move the break room 1 in and out.
