[0048] (Embodiment)

[0049] <Structure: Rest room 1>

[0050] First, the structure of the rest room 1 of the present embodiment will be described.

[0051] Figure 1 is a perspective view showing the appearance of the rest room 1 of the embodiment.

[0052] As shown in Figure 1 , the rest room 1 is formed with an indoor space R which accommodates a bed 30 for a user to sleep or rest. The user can reduce drowsiness or eliminate fatigue by sleeping or resting in the indoor space R.

[0053] Further, in the rest room 1, the indoor space R can be illuminated. For example, in the case where the rest room 1 is used as a nap room, when a wake-up desired time is set, it can be set to be lit from a time before the wake-up desired time. Further, in the case where the rest room 1 is used as a rest room, the indoor space R can be illuminated. In the present embodiment, the wake-up includes not only the user getting up from the bed, but also just waking up.

[0054] Further, in the rest room 1, the air quality of the indoor space R can be adjusted by taking in air from the outside space. The air quality is the temperature, humidity, amount of aromatic component, and the like of the air in the indoor space R.

[0055] Further, 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. Further, the rest room 1 can be configured to be immovable by locking the casters 12.

[0056] Further, the rest room 1 is set to be the size that can get on an elevator. Specifically, the outer dimensions of the rest room 1, that is, the length (width) of the rest room 1 along the Y-axis direction x the length of the rest room 1 along the X-axis direction x the length (height) of the rest room 1 along the Z-axis direction is 1100 mm or less x 2100 mm or less x 1950 mm or less.

[0057] Further, the rest room 1 is set to a size in which a person can lie down in a normal standing posture. Specifically, lower limit values of the outer dimensions of the room 10, that is, respective lower limit values of the length (width) of the rest room 1 along the Y-axis direction, the length of the rest room 1 along the X-axis direction, and the length (height) of the rest room 1 along the Z-axis direction are 600 mm or more, 1900 mm or more, and 1000 mm or more, respectively. That is, in the rest room 1, by setting the lower limit value of the width to 600 mm or more, it is possible to set to be about 50 cm or more, which is the shoulder width of a person. Further, in the rest room 1, by setting the lower limit value of the length to 1900 mm or more, it is possible to set so that a person with a height of 190 cm can lie down in the rest room 1. Further, in the rest room 1, by setting the lower limit value of the height to 1000 mm or more, it is possible to set to be about 90 cm or more, which is the sitting height of a person.

[0058] Hereinafter, the specific structure of the rest room 1 will be described.

[0059] The rest room 1 has the room 10, the duct 20, and the lighting system 3.

[0060] [Room 10]

[0061] The room 10 is provided with an entrance 19 through which a user enters and exits. In the present embodiment, the entrance 19 is provided at a central portion in the X-axis direction of the room 10 on the negative side of the Y-axis of the room 10. In the present embodiment, the entrance 19 is provided on the side of the room 10 on which the bed 30 is not provided. Figure 1 In the present embodiment, a door that opens and closes the entrance 19 is not illustrated, but the entrance 19 can be provided with a door.

[0062] Further, the room 10 forms an indoor space R in which a user sleeps. In the room 10, a long bed 30 is disposed, so the indoor space R is long in the X-axis direction in correspondence with the size of the bed 30.

[0063] Figure 2 is a block diagram that shows the rest room 1 of the embodiment.

[0064] As shown in Figure 1 and Figure 2 , the room 10 is a housing that is formed in a rectangular parallelepiped shape to a size in which a user can sleep. The room 10 houses the bed 30, the duct 20, the operation device 40, the first lighting fixture 71, the second lighting fixture 72, the wake-up time setting section 90, the audio device 61, the air blower 62, the aroma device 63, and the power supply section 80. In addition, as for the audio device 61, the air blower 62, and the aroma device 63, it is sufficient that at least one of the audio device 61, the air blower 62, and the aroma device 63 is provided in the room 10.

[0065] Figure 3 is a view that shows the indoor space R of the rest room 1 of the embodiment.

[0066] As shown inFigure 1 and Figure 3 As shown, when viewing the interior space R of room 10 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 room 10 on the side of entrance 19, and a third space R3 between the bed 30 and the long side of room 10 on the side of entrance 19, on the foot side when the user is sleeping on the bed 30. The first space R1 is represented by the shaded dots, the second space R2 by the shaded diagonal lines, and the third space R3 by the shaded grid.

[0067] The second space R2 and the third space R3 are located on the negative Y-axis side relative to the first space R1. Furthermore, the third space R3 is located on the negative X-axis side relative to the second space R2, at the foot of the user when sleeping on the bed 30. The first space R1 houses the operating device 40 and the bed 30, the second space R2 houses the floor 11b of the room 10, and the third space R3 houses a blower 62, an aromatherapy device 63, a second lighting fixture 72, and... Figure 2 Power supply section 80, etc.

[0068] like Figure 1 As shown, room 10 has multiple frames 11, multiple casters 12, multiple wall sections 11f, and a ceiling 13.

[0069] The multiple frames 11 have a frame-shaped base 11a, a floor 11b, multiple columns 11c, and a top frame 11d.

[0070] The base 11a is a rectangular frame positioned approximately parallel to the XY plane and vertically below the room 10 (in the negative Z-axis direction). At least one set of casters 12, corresponding one-to-one with each corner, are provided on the end face of the base 11a in the negative Z-axis direction. Therefore, the base 11a is positioned facing the ground with respect to the casters 12.

[0071] The caster 12 can rotate when the room 10 moves relative to the ground, or it can be locked so that the wheels do not rotate. The caster 12 is an example of a moving part.

[0072] The base 11a is connected to multiple keel beams 11a1. A floor 11b is provided above the base 11a and the multiple keel beams 11a1. The floor 11b is longer along the X-axis. The floor 11b is located between the bed 30 and the entrance 19 of the room 10, and is arranged in the second space R2 above the base 11a and the multiple keel beams 11a1.

[0073] Multiple columns 11c are elongated, extending from each corner of the base 11a along the Z-axis, and support the upper frame 11d.

[0074] Further, some of the plurality of columns 11c are adjacently arranged in order to form a third space R3. Specifically, some of the columns 11c that form the third space R3 are composed of at least a first column 11cl, a second column 11c2, and a third column 11c3. The first column 11cl is arranged at a corner portion of the base 11a that is the end portion in the negative direction of the X axis and the end portion in the negative direction of the Y axis. The second column 11c2 is arranged adjacent to the first column 11cl in the positive direction of the X axis from the first column 11cl. The third column 11c3 is arranged adjacent to the first column 11cl in the positive direction of the Y axis from the first column 11cl.

[0075] The plurality of wall portions 11f are partition walls that define the indoor space R. Some of the plurality of wall portions 11f are arranged between two adjacent columns 11c of the plurality of columns 11c.

[0076] In Figure 1 In the drawing, the wall portions 11f are omitted except for a first wall portion 11fl and a second wall portion 11f2. One or more wall portions 11f are arranged around the bed 30, for example, in at least one of the front, rear, left, and right directions with respect to the bed 30.

[0077] Further, the first wall portion 11fl and the second wall portion 11f2, which are some of the plurality of wall portions 11f, are arranged around the air blower 62, the fragrance device 63, and the like. The first wall portion 11fl is arranged between the first column 11cl and the second column 11c2. The second wall portion 11f2 is arranged between the first column 11cl and the third column 11c3. Further, the first wall portion 11fl and the second wall portion 11f2 constitute a part of the short side of the room 10 as an outer wall (an outer shell) of the room 10. The first wall portion 11fl and the second wall portion 11f2 are examples of the wall portions 11f.

[0078] Further, the second column 11c2 is connected to a light shielding portion 11f3 that extends in the positive direction of the Y axis from the second column 11c2 and is arranged between the second space R2 and the third space R3.

[0079] The upper frame 11d is a rectangular frame that is arranged in a posture substantially parallel to the XY plane in the vertical direction (the positive direction of the Z axis) above the room 10. The upper frame 11d is supported by the plurality of columns 11c corresponding to the base 11a. In the present embodiment, two upper frames 11d are provided. The first lighting device 71 and the duct 20 are arranged between the two upper frames 11d.

[0080] A ceiling 13 is provided in the upper frame 11d. In the ceiling 13, the duct 20 and an air outlet 20a that is an opening of the duct 20 are provided. The duct 20 guides air that is sucked in from an air inlet 20b to the air outlet 20a. That is, the duct 20 forms a flow path of air flow by connecting the air outlet 20a and the air inlet 20b.

[0081] Air is drawn in from the inlet 20b and blown out through the duct 20 via the outlet 20a. The outlet 20a is positioned on the upper or lower side of the user's body when sleeping on the bed 30. In this embodiment, the outlet 20a is installed on the ceiling 13 opposite the bed 30, positioned opposite the lower side of the user's body when sleeping on the bed 30.

[0082] Furthermore, the outlet 20a is positioned away from the inlet 20b and the blower 62. That is, the wall 11f (i.e., ceiling 13) of the room 10 where the outlet 20a is located and the wall 11f of the room 10 where the inlet 20b is located are different wall 11f. In this way, by separating the outlet 20a and the inlet 20b as much as possible, sound and light entering from the inlet 20b are not transmitted to the outlet 20a.

[0083] The intake vent 20b is positioned at the foot of the user when they are sleeping on the bed 30. Furthermore, the intake vent 20b is located on the outer wall of the room 10, facing the external space of the room 10. Therefore, the intake vent 20b can draw in air from the external space of the room 10. In this embodiment, the intake vent 20b is positioned opposite the blower 62 to allow communication between the external space and the third space R3.

[0084] [Lighting System 3]

[0085] like Figure 1 and Figure 2 As shown, if the user sets a desired wake-up time, the lighting system 3 executes a wake-up mode to wake the user at that desired time. This mode wakes the user by turning on the first lighting fixture 71 and the second lighting fixture 72.

[0086] 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 part 11f3, a wake-up time setting part 90, an audio device 61, a blower 62, an aromatherapy device 63, and a power supply part 80. Alternatively, the lighting system 3 may include only one of the audio device 61, the blower 62, and the aromatherapy device 63, or it may not include all of these devices.

[0087] The bed 30 provides a place for the user to sit and sleep. Furthermore, the bed 30 is elongated along the X-axis in the first space R1. In this embodiment, the bed 30 is supported by multiple columns 11c, but it can also be placed on a base 11a and multiple keel beams 11a1.

[0088] The bed 30 is set such that the user's head is located on the positive X-axis side of the bed 30, and the feet are located on the negative X-axis side of the bed 30.

[0089] Further, the bed 30 of the present embodiment includes a structure that functions as a bed by deforming a chair. Specifically, the bed 30 can also have a seat portion on which a user sits, a leg rest portion rotatably coupled to the seat portion, a back rest portion rotatably coupled to the seat portion, and a head rest coupled to the back rest portion. In this case, the chair can also function as a bed obtained by arranging the leg rest portion, the seat portion, the back rest portion, and the head rest in a straight line. Further, the bed 30 of the present embodiment is also capable of being inclined and can also be deformed like a chair. In addition, in the case of a chair, the illuminance of the surface of the back rest portion and the illuminance of the surface of the head rest in a case where the user leans his back against the back rest portion and places his head on the head rest correspond to the bed surface illuminance in the head region Rla.

[0090] The operation device 40 is disposed on the positive direction side of the X axis of the bed 30 in the first space Rl. That is, in a case where the user sleeps in the bed 30, the operation device 40 is disposed in the vicinity of the head. In addition, the operation device 40 can be disposed in one or more of the first space Rl, the second space R2, and the third space R3. That is, the operation device 40 can also be provided in plurality in the rest room 1.

[0091] Further, the operation device 40 can be capable of operating the sound device 61, the air blower 62, and the aroma device 63 individually by the user. That is, the operation device 40 outputs an instruction operated by the user to the control device 60, and the control device 60 causes the sound device 61, the air blower 62, and the aroma device 63 to be driven or causes the driving to be stopped, respectively. In addition, the operation device 40 can also be capable of operating only at least one of the sound device 61, the air blower 62, and the aroma device 63. Further, the operation device 40 can also be capable of individually operating the first lighting fixture 71 and the second lighting fixture 72, respectively.

[0092] The control device 60 can be capable of controlling the sound device 61, the air blower 62, and the aroma device 63 according to an instruction from the operation device 40. In addition, the control device 60 can also be capable of controlling only at least one of the sound device 61, the air blower 62, and the aroma device 63. Further, the control device 60 can also be capable of controlling the first lighting fixture 71 and the second lighting fixture 72.

[0093] Here, the control of the sound device 61, the air blower 62, and the aroma device 63 by the control device 60 will be described.

[0094] For example, if the user operates the operation device 40 to input an instruction, the control device 60 instructs the sound device 61 to reproduce music according to the instruction obtained from the operation device 40. Thereby, the sound device 61 reproduces the music, and the reproduced music is output to the indoor space R. Further, the control device 60 can be capable of changing the music reproduced by the sound device 61 or controlling the volume of the music output by the sound device 61 by obtaining the instruction from the operation device 40.

[0095] Further, if the user operates the operation device 40 to input an instruction to make the air blower 62 from the off state to the on state, the control device 60 sets the power supply of the air blower 62 to on in accordance with the instruction obtained from the operation device 40. Thereby, the air blower 62 is driven to take in the air of the outside space into the indoor space R of the room 10. Further, the control device 60 can control the output of the air blower 62, that is, the rotation speed of the fan of the air blower 62, by obtaining the instruction from the operation device 40.

[0096] Further, if the user operates the operation device 40 to input an instruction to make the air blower 62 from the off state to the on state, the control device 60 sets the power supply of the air blower 62 to on in accordance with the instruction obtained from the operation device 40. Thereby, the air blower 62 is driven to take in the air of the outside space into the indoor space R of the room 10. Further, the control device 60 can control the output of the air blower 62, that is, the rotation speed of the fan of the air blower 62, by obtaining the instruction from the operation device 40.

[0097] The first lighting fixture 71 and the second lighting fixture 72 can illuminate the indoor space R. Further, the first lighting fixture 71 and the second lighting fixture 72 have a dimming function of changing the light amount. For example, the first lighting fixture 71 and the second lighting fixture 72 perform dimming control by obtaining a dimming instruction from the wake-up time setting section 90. Thereby, the first lighting fixture 71 and the second lighting fixture 72 can change the brightness of the light emitted. Note that it is sufficient that at least one of the first lighting fixture 71 and the second lighting fixture 72 has the dimming function of changing the light amount.

[0098] Further, the first lighting fixture 71 and the second lighting fixture 72 can also dim and color according to a direct instruction from the operation device 40.

[0099] Further, the first lighting fixture 71 is disposed vertically above the upper half of the body of the user when the user is in bed 30. Specifically, the first lighting fixture 71 is provided to the ceiling 13. Further, the first lighting fixture 71 is disposed in a manner of being buried in the ceiling 13. Note that it is sufficient that the first lighting fixture 71 is provided in the indoor space R. More specifically, as shown in FIG. 1, it is sufficient that the first lighting fixture 71 is disposed so that the distance between the first lighting fixture 71 and the head region Rla, which is a region of the surface of the bed 30 where the head is disposed when the user is in bed 30, is 1.5 m or less. Figure 4 Figure 4 is a diagram showing the distance between the head region Rla of the rest room 1 according to the embodiment and the first lighting fixture 71. Here, the head region Rla is a region of the surface of the bed 30 where the head is disposed when the user is in bed 30.

[0100] ​The second lighting fixture 72 is disposed at the foot side when the user is in bed on the bed 30. Specifically, the second lighting fixture 72 is arranged in the third space R3. Further, the second lighting fixture 72 can also be provided in plurality in the third space R3. Further, the second lighting fixture 72 can also be arranged in a manner of being buried in the light shielding portion 1 If3.

[0101] The light shielding portion 1 If3 is arranged between the second lighting fixture 72 and the head region Rla. Specifically, the light shielding portion 1 If3 is arranged at the boundary between the first space Rl and the third space R3 at the foot side when the user is in bed on the bed 30. Therefore, the light shielding portion 1 If3 is substantially parallel to the YZ plane, and can perform light shielding so that the light emitted from the second lighting fixture 72 does not directly shine on the head of the user when in bed on the bed 30.

[0102] Further, the light shielding portion 1 If3 is arranged in opposition to the second wall portion 1 If2 with the second lighting fixture 72 interposed therebetween. Therefore, the light shielding portion 1 If3 forms, together with the second wall portion 1 If2, an opening portion 1 Ih through which the light irradiated by the second lighting fixture 72 passes. Thereby, if the second lighting fixture 72 is lit, the light emitted from the second lighting fixture 72 is reflected by the light shielding portion 1 If3 and the second wall portion 1 If2 and is emitted from the opening portion 1 Ih, and is further reflected by the wall portions 1 If of the room 10 and the bed 30 and the like to be irradiated toward the head region Rla.

[0103] The wake-up time setting portion 90 has a switch or a touch panel or the like by which the user can set the wake-up time of himself or herself when in bed on the bed 30. By setting the wake-up time, the wake-up time setting portion 90 controls the driving of the first lighting fixture 71 and the second lighting fixture 72. Specifically, when the input of the wake-up desired time is accepted by the operation of the user, the wake-up time setting portion 90 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 wake-up desired time. More specifically, the wake-up time setting portion 90 outputs the indication of the input wake-up desired time, and thereby at least one of the first lighting fixture 71 and the second lighting fixture 72 is driven from t seconds before the wake-up desired time. Thereby, at least one of the first lighting fixture 71 and the second lighting fixture 72 is lit from t seconds before the wake-up desired time. In this way, the wake-up time setting portion 90 can have a lighting control portion that controls the driving of the first lighting fixture 71 and the second lighting fixture 72. Further, such a lighting control portion can be arranged independently from the wake-up time setting portion 90, can be mounted on the control device 60, or can be mounted on each of the first lighting fixture 71 and the second lighting fixture 72.

[0104] Here, t seconds is a time set in advance, and for example, 900 seconds or less is preferable. This is because, since the user uses the rest room 1 with the purpose of a nap and goes to bed, if t seconds is too long compared to 900 seconds, the nap time of the user becomes short. Therefore, by setting the upper limit value of t seconds to 900 seconds, it is possible to ensure sufficient nap time of the user.

[0105] Further, the wake-up time setting portion 90 changes the light amount of at least one of the first lighting instrument 71 and the second lighting instrument 72, and changes the surface illuminance of the bed 30 of the head region Rla with time until the wake-up desired time is reached. That is, at least one of the first lighting instrument 71 and the second lighting instrument 72 changes the light amount of the emitted light from t seconds before the wake-up desired time to the wake-up desired time, and thereby the bed surface illuminance is changed with time. Here, by the change with time, it means that the bed surface illuminance has a change of ±10 lx or more in 60 seconds. In addition, the bed surface illuminance is preferably gradually increased with the passage of time.

[0106] Here, the bed surface illuminance is the illuminance of the surface of the bed 30 when at least one of the first lighting instrument 71 and the second lighting instrument 72 is lit. Therefore, the bed surface illuminance of the head region Rla is the illuminance of the surface of the bed 30 where the head is disposed when the user goes to bed on the bed 30. In the present embodiment, the bed surface illuminance in the head region Rla is considered to be equivalent to the illuminance of the head of the user who goes to bed on the bed 30, that is, the face surface illuminance.

[0107] Further, the wake-up time setting portion 90 is disposed on the side opposite to the side where the second lighting instrument 72 is disposed in the longer direction of the bed 30. That is, the wake-up time setting portion 90 is disposed on the head side when the user goes to bed on the bed 30. Therefore, the user can operate the wake-up time setting portion 90 while lying down.

[0108] Further, the wake-up time setting portion 90 can be integrally constituted with the operation device 40. Further, the wake-up time setting portion 90 can also be constituted independently from the operation device 40.

[0109] The sound device 61 can provide the user with music having a sleep-inducing effect or music having a wake-up effect by reproducing music in the room 10. The sound device 61 is housed in the room 10, and for example, is disposed in the indoor space R. The sound device 61 can change the music played in the indoor space R or adjust the volume by being operated by the user with the operation device 40.

[0110] The air supply fan 62 is arranged in the room 10, takes in air from the air inlet 20b provided in the room 10, and blows out air from the air outlet 20a provided in the indoor space R, thereby generating an air current in the indoor space R. The air supply fan 62 is capable of adjusting the temperature and humidity of the air in the indoor space R by taking in air from the outside and driving.

[0111] Thus, the air supply fan 62 is capable of generating an air current from the air inlet 20b toward the air outlet 20a by driving in a state of being arranged at the air inlet 20b side of the duct 20. Further, the air supply fan 62 is capable of intensifying or not intensifying the air blown to the user who is in bed on the bed 30, since it is capable of blowing out air from the air outlet 20a. The output of such an air supply fan 62 is capable of being adjusted by the operation device 40.

[0112] Further, the air supply fan 62 is arranged at the foot side of the user when in bed on the bed 30. Further, the air supply fan 62 is arranged on the flow path of the duct 20. In the present embodiment, the air supply fan 62 is arranged in the third space R3 opposite to the air inlet 20b so as to be at the same height as the air inlet 20b, and is arranged away from the user's head on the ceiling 13 side than the bed 30.

[0113] The fragrance device 63 is arranged in the room 10, and is capable of adjusting the amount of fragrance in the indoor space R by introducing a fragrance to the air blown out from the air outlet 20a. For example, the fragrance device 63 is capable of causing a fragrance to be contained in the air from the air inlet 20b toward the air outlet 20a by the driving of the air supply fan 62 by the control of the control device 60. That is, the fragrance is guided into the indoor space R by riding on the air current from the air inlet 20b toward the air outlet 20a. Thus, the indoor space R can be filled with a fragrance preferred by the user. The output of such a fragrance device 63 is capable of being adjusted by the operation device 40.

[0114] Further, the fragrance device 63 is capable of introducing a fragrance to the indoor space R even if the air supply fan 62 is not driven. That is, the fragrance device 63 is capable of filling the indoor space R with the fragrance of a fragrance just by being arranged in the indoor space R.

[0115] Further, the fragrance device 63 is arranged at the foot side of the user when in bed on the bed 30. Specifically, the fragrance device 63 is arranged on the flow path of the duct 20 or in the third space R3. In the present embodiment, the fragrance device 63 is arranged on the downstream side (air outlet 20a side) than the air supply fan 62, and is arranged away from the user's head on the ceiling 13 side than the air supply fan 62.

[0116] In this embodiment, the blower 62 and the aromatherapy diffuser 63 are located on the side of the ceiling 13 in the negative Z-axis direction (below), but this is not a limitation. Alternatively, only the blower 62 may be located on the side of the ceiling 13 in the negative Z-axis direction. In this embodiment, the blower 62 and the aromatherapy diffuser 63 are positioned at the foot of the user when sleeping on the bed 30, but this is not a limitation. Alternatively, only the blower 62 may be positioned at the foot of the user when sleeping on the bed 30. In these cases, the aromatherapy diffuser 63 may be positioned above the ceiling 13 or near the outlet 20a of the duct 20.

[0117] 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 by supplying power to the sound device 61, the blower 62, and the aromatherapy device 63. That is, the power supply unit 80 generates drive power to drive the first lighting fixture 71, the second lighting fixture 72, the sound device 61, the blower 62, and the aromatherapy device 63, and supplies the drive power to the first lighting fixture 71, the second lighting fixture 72, the sound device 61, the blower 62, and the aromatherapy device 63 respectively.

[0118] [bed surface illumination]

[0119] Here, we describe the bed surface illuminance in the head area R1a from t seconds before the desired wake-up time to the desired wake-up time when the lighting system 3 is executing the lighting mode to wake the user.

[0120] like Figure 5A As shown, the interval from t seconds before the desired wake-up time to t1 seconds before the desired wake-up time (which is t seconds before t seconds ago) is designated as the first interval, and the interval from t1 seconds to the desired wake-up time is designated as the second interval. Figure 5A It is a graph representing the bed surface illuminance from t seconds before the desired wake-up time to the desired wake-up time.

[0121] In the first interval, the second lighting fixture 72 is turned on so that the average time-varying illuminance of the bed surface in the head area R1a is less than 100 lx. Furthermore, in the first interval, the maximum illuminance of the bed surface in the head area R1a is 1 lx or more due to the illumination of the second lighting fixture 72. In addition, in the first interval, the first lighting fixture 71 is turned off. This is because if a bright light were suddenly brought to a sleeping user, the user would be abruptly awakened, resulting in an unpleasant experience. Therefore, in the first interval, the wake-up time setting unit 90 controls the second lighting fixture 72 to a brightness level that is not likely to wake the user, i.e., dim, so that the illuminance of the bed surface in the head area R1a is less than 100 lx and more than 1 lx. Thus, in the first interval, the sleeping user can become accustomed to the light from the second lighting fixture 72.

[0122] In the second interval, at least the first lighting fixture 71 is lit to make the maximum value of the floor surface illuminance in the head region Rla 100 lx or more. For example, in the second interval, the time maximum value of the floor surface illuminance in the head region Rla is 100 lx or more in the case where only the first lighting fixture 71 is lit. Further, in the second interval, the state where mainly the first lighting fixture 71 is lit, but it is also possible that the second lighting fixture 72 is also lit. In this case, in the second interval, at the stage where the illuminance of the head by the second lighting fixture 72 becomes a certain brightness, the first lighting fixture 71 can be turned off. Thereby, the user does not easily notice the turning off of the first lighting fixture 71, so does not easily feel the discomfort caused by the turning off. As a result, it is possible to suppress the increase in the power consumption of the lighting system 3.

[0123] Here, the second interval is preferably, for example, in the range of approximately 60 seconds to 600 seconds. By setting the upper limit value of the second interval to be within 600 seconds, it is possible to delay as much as possible the time point at which the first lighting fixture 71 is lit to directly irradiate light to the head of the user. Thereby, it is possible to secure the dozing time of the user. Further, by setting the lower limit value of the second interval to be 60 seconds or more, it is possible to make the brightness of the light directly irradiated to the head of the user by the lighting of the first lighting fixture 71 not change drastically. Thereby, it is possible to not cause the user to feel the unpleasantness caused by the drastic change in the brightness.

[0124] Further, in the second interval, the time maximum value of the floor surface illuminance in the head region Rla is 700 lx or more. Specifically, in the case where the second interval is divided into the second-1 interval and the second-2 interval which is later than the second-1 interval, in the second-2 interval, the time maximum value of the floor surface illuminance in the head region Rla is 700 lx or more. That is, in the second interval, at a time point close to the time of the desired wake-up, the time maximum value of the floor surface illuminance in the head region Rla becomes 700 lx or more. Specifically, at a latter half of the time point close to the desired wake-up, at least the first lighting fixture 71 irradiates light of high illuminance to make the floor surface illuminance in the head region Rla 700 lx or more. Therefore, the user can be awakened.

[0125] Further, in the second-1 interval, the maximum value of the floor surface illuminance in the head region Rla is 100 lx or more. That is, in the second-1 interval, the floor surface illuminance in the head region Rla is brighter than in the first interval in order to make the user wake up.

[0126] Further, the time during which the floor surface illuminance in the head region Rla is 700 lx or more is in the range of approximately 10 seconds to 60 seconds.

[0127] t seconds is set by the wake-up time setting section 90 in accordance with the length of the sleep period, which is the period from the time at which the user sets the wake-up desired time to the wake-up desired time using the wake-up time setting section 90. That is, if the length of the sleep period, which is the period from the time at which the wake-up desired time is set to the wake-up desired time, becomes longer, the wake-up time setting section 90 sets t seconds to be longer. On the other hand, if the length of the sleep period, which is the period from the time at which the wake-up desired time is set to the wake-up desired time, becomes shorter, the wake-up time setting section 90 sets t seconds to be shorter.

[0128] Here, the use of Figure 5A to Figure 5F is described.

[0129] Figure 5A to Figure 5C , Figure 5E , Figure 5F The second interval of Figure 5D is longer than the second interval of Figure 5D is shorter than the second interval of Figure 5A to Figure 5F The lighting control in Figure 5A to Figure 5F is merely an example, and the lighting system 3 is not limited to

[0130] For example, as shown in Figure 5A , the first interval can be set to be shorter, and the second interval can be set to be longer than the first interval.

[0131] Next, Figure 5B is another graph showing the bed surface illuminance from t seconds before the wake-up desired time to the wake-up desired time. As shown in Figure 5B , the first interval can be set to be shorter, and the second interval can be set to be longer than the first interval. Further, it can be that, in the first interval of Figure 5B , the wake-up time setting section 90 sets the period in which the bed surface brightness is dark to be longer than the first interval of Figure 5A , and in the second interval of Figure 5B , the wake-up time setting section 90 sets the period in which the bed surface brightness is bright to be shorter than the second interval of Figure 5A . Furthermore, in Figure 5B , the period in which the bed surface illuminance is the maximum value can be set to be shorter than Figure 5A .

[0132] Next, Figure 5C is another graph showing the bed surface illuminance from t seconds before the wake-up desired time to the wake-up desired time. Further, as shown in Figure 5C , the first interval can be set to be longer, and the second interval can be set to be shorter than the first interval. Further, it can be that, in the first interval of Figure 5C , the wake-up time setting section 90 sets the period in which the bed surface brightness is dark to be longer than the first interval ofFigure 5B The length of the first interval is... Figure 5C In the second section, the brightness of the bed surface is set to be brighter for a longer period than... Figure 5B The second interval is shorter. Therefore, in Figure 5C In this case, the period during which the bed surface illuminance is at its maximum can be set to be more than... Figure 5B short.

[0133] then, Figure 5D This is another graph showing the bed surface illuminance from t seconds before the desired wake-up time to the desired wake-up time. Furthermore, as... Figure 5D As shown, the first interval can be set to be longer, and the second interval can be set to be shorter than the first interval. Furthermore, the wake-up time setting unit 90 can... Figure 5D In the first interval, the period of darkness for the bed surface brightness is set to be greater than... Figure 5C The length of the first interval is... Figure 5D In the second section, the brightness of the bed surface is set to be brighter for a longer period than... Figure 5C The second interval is short.

[0134] then, Figure 5E This is a graph representing the low bed surface illuminance from t seconds before the desired wake-up time to the desired wake-up time. Additionally, as... Figure 5E As shown, the wake-up time setting unit 90 may have a first interval where the bed surface illuminance increases very gradually, and a second interval where the bed surface illuminance increases at a steeper slope than the first interval. In this case, the second lighting fixture 72 provides illumination, but in the first interval, the bed surface illuminance is very low, i.e., the bed surface is dark. Furthermore, in the second interval, the bed surface illuminance increases rapidly and becomes bright.

[0135] then, Figure 5F This is another graph representing the low bed surface illuminance from t seconds before the desired wake-up time to the desired wake-up time. Additionally, as... Figure 5F As shown, the wake-up time setting unit 90 may have a first interval where the bed surface illuminance increases gradually and a second interval where the bed surface illuminance increases more rapidly than the first interval. In this case, the second lighting fixture 72 provides illumination, but in the first interval, the bed surface illuminance is low, i.e., the bed surface is dim. In the second interval, the bed surface illuminance increases sharply and becomes bright.

[0136] In such Figure 5A to Figure 5D In situations where users have short nap times, there are users who want to maximize their nap duration. In such cases, even if settings are configured... Figure 5A During that lighting control period, the user can also choose... Figure 5B and Figure 5C This allows for lighting control with a shorter duration, such as longer control periods. In this way, the user can select the desired lighting control duration according to their preference by operating the control device 40.Figure 5A Short lighting control.

[0137] In addition, Figure 5E and Figure 5F In this design, the first illuminance zone is set to be relatively long, so that the illuminance of the head area R1a is reduced by the illumination from the second illuminator 72. This is intended to induce a lighter sleep in the user without waking them. Furthermore, by briefly brightening the illuminance of the head area R1a after the user's sleep has become lighter, the unpleasant feeling upon waking can be suppressed. Therefore, during deep sleep, it is less likely that the user's unpleasant feeling will increase due to a sudden increase in bed surface illuminance.

[0138] <Processing Action>

[0139] Figure 6 This is a flowchart illustrating the processing actions of the lounge 1 in the implementation method.

[0140] First, the user inputs their desired wake-up time into the wake-up time setting unit 90. Then, the wake-up time setting unit 90... Figure 6 As shown, the desired wake-up time is obtained by accepting the input of the desired wake-up time (S11).

[0141] Next, the wake-up time setting unit 90 calculates the period from the time point where the desired wake-up time is set to the time of bedtime. Furthermore, based on the length of the bedtime, the wake-up time setting unit 90 sets the start time for turning on the second lighting fixture 72, starting from a time earlier than the desired wake-up time. Specifically, the wake-up time setting unit 90 sets the time t seconds (S12) for turning on the first lighting fixture 71 and the second lighting fixture 72 to wake the user. That is, the wake-up time setting unit 90 sets the time t seconds before the desired wake-up time.

[0142] Next, the wake-up time setting unit 90 determines whether it is t seconds before the desired wake-up time (S13).

[0143] If it is not t seconds before the desired wake-up time ("No" in S13), the wake-up time setting unit 90 returns the processing action to step S13.

[0144] On the other hand, if t seconds before the wake-up desired time elapses (YES in S13), the wake-up time setting section 90 causes the second lighting instrument 72 to start lighting (S14). That is, the lighting system 3 starts to execute the lighting mode for causing the user to wake up. Specifically, the wake-up time setting section 90 causes only the second lighting instrument 72 to light so as not to wake up the user in the first section from t seconds before the wake-up desired time to t1 seconds before the wake-up desired time, and gradually increases the light amount of the second lighting instrument 72 so that the maximum value of the bed surface illuminance in the head region Rla becomes 1 lx or more. The light emitted from the second lighting instrument 72 is blocked by the light shielding section 1 If, and thus the light does not directly strike the user's head, so the bed surface in the head region Rla becomes dim.

[0145] Next, the wake-up time setting section 90 determines whether or not t1 seconds before the wake-up desired time elapses (S15).

[0146] If t1 seconds before the wake-up desired time does not elapse (NO in S14), the wake-up time setting section 90 causes the processing to return to step S14.

[0147] On the other hand, if t1 seconds before the wake-up desired time elapses (YES in S14), the wake-up time setting section 90 causes at least the first lighting instrument 71 to start lighting (S15). Specifically, in the second section from t1 seconds before the wake-up desired time to the wake-up desired time, in order to wake up the user, the wake-up time setting section 90 causes at least the first lighting instrument 71 to light, and thus gradually increases the light amount of the first lighting instrument 71 in such a manner that the maximum value of the bed surface illuminance in the head region Rla becomes 100 lx or more, and preferably 700 lx or more. Since the light emitted from the first lighting instrument 71 directly strikes the user's head, the bed surface in the head region Rla becomes bright.

[0148] In this way, by dimming the bed surface in the head region Rla in the first section in such a manner that the light does not directly strike the user's head, and making it bright in the following second section in such a manner that the light directly strikes the user's head, the user is adapted to the light. Therefore, the user can wake up at the wake-up desired time without feeling much unpleasantness.

[0149] <Effects>

[0150] Next, the effects of the rest room 1 of the present embodiment will be described.

[0151] As described above, the lighting system 3 of the present embodiment has the bed 30 on which the user sleeps, the first lighting fixture 71, the second lighting fixture 72, and the light shielding portion 1 If3. Further, at least one of the first lighting fixture 71 and the second lighting fixture 72 has a dimming function that changes the light quantity. Further, the distance between the first lighting fixture 71 and the head region Rla, which is the region in which the head is disposed when the user sleeps on the bed 30, is 1.5 m or less. Further, the second lighting fixture 72 is disposed on the foot side when the user sleeps on the bed 30. Also, the light shielding portion 1 If3 is disposed between the second lighting fixture 72 and the head region Rla.

[0152] Thus, even if the second lighting fixture 72 emits light, the light is shielded by the light shielding portion 1 If3, so it is possible to suppress the light emitted by the second lighting fixture 72 from directly shining on the head region Rla. That is, the light emitted by the second lighting fixture 72 is less likely to directly shine on the head of the user who sleeps on the bed 30. Thus, it becomes indirect lighting in which the direct shining of the light of the second lighting fixture 72 on the eyes of the user is suppressed, so it is possible to suppress the unpleasant feeling of the user when getting up.

[0153] Further, for example, after the second lighting fixture 72 is caused to emit light, the first lighting fixture 71 is caused to emit light so as to illuminate the head region Rla, so the first lighting fixture 71 can shine bright light on the user.

[0154] Thus, in the lighting system 3, it is possible to suppress the unpleasant feeling of the user when getting up while maintaining a high wakefulness assistance effect.

[0155] Further, the lighting system 3 of the present embodiment also has the getting-up time setting portion 90. Also, if the getting-up desired time is input, the getting-up time setting portion 90 changes the light quantity of at least one of the first lighting fixture 71 and the second lighting fixture 72 from t seconds before the getting-up desired time, so as to change the illuminance of the surface of the bed 30 in the head region Rla, i.e., the bed surface illuminance, over time.

[0156] Thus, the bed surface illuminance in the head region Rla gradually changes from t seconds before the getting-up desired time. For example, the head of the user who sleeps on the bed 30 gradually brightens, so the user can get up without feeling the unpleasant feeling when getting up.

[0157] Further, the lighting system 3 of the present embodiment has a first interval from t seconds before the getting-up desired time to t1 seconds before the getting-up desired time after the time elapses from t seconds, in which the time average of the bed surface illuminance in the head region Rla is less than 100 lx. Also, in a second interval from t1 seconds to the getting-up desired time, the maximum value of the bed surface illuminance in the head region Rla is 100 lx or more.

[0158] Thus, by making the bed surface illuminance in the head region Rla less than 100 lx in the first interval, the user can be made to get out of bed without being disturbed by the light from the first and second lighting fixtures 71 and 72 in the first interval. Further, in the second interval after the first interval, by making the bed surface illuminance 100 lx or more, the user can be made to get out of bed. In this way, the head region Rla is slightly illuminated from t seconds before the get-out-of-bed desired time in the first interval, and the head region Rla is brightly illuminated from ti seconds before the get-out-of-bed desired time in the second interval, whereby the bed surface illuminance of the head region Rla can be made to gradually brighten. Thus, in the lighting system 3, the user's unpleasant feeling at the time of getting out of bed can be further suppressed.

[0159] Further, in the lighting system 3 of the present embodiment, in the first interval, the first lighting fixture 71 is turned off.

[0160] Thus, in the first interval, the first lighting fixture 71 is not lit, so light is not directly irradiated to the head of the user who is in bed 30. Therefore, the user is not easily made to get out of bed in the first interval, so the user is not easily made to feel an unpleasant feeling.

[0161] Further, in the lighting system 3 of the present embodiment, in the first interval, when the second lighting fixture 72 is lit, the maximum value of the bed surface illuminance in the head region Rla is 1 lx or more.

[0162] For example, if a user is directly irradiated with light while sleeping, the user feels an unpleasant feeling due to a sharp change in brightness.

[0163] However, according to the present embodiment, in the first interval, the space as a whole can be made to brighten to a certain degree in advance by indirect lighting without directly irradiating light to the user's head. Therefore, even if the head region Rla is gradually made to brighten in the second interval while directly irradiating light to the user's head, since the user is adapted to the light, the user does not easily feel a sharp change in brightness, and does not easily feel an unpleasant feeling.

[0164] Further, in the lighting system 3 of the present embodiment, in the second interval, in the case where only the first lighting fixture 71 is lit, the temporal maximum value of the bed surface illuminance in the head region Rla is 100 lx or more.

[0165] For example, in the second interval, if there is no lighting of the first lighting fixture 71, there is a case where the effect of waking up the user who is sleeping is insufficient.

[0166] However, according to the present embodiment, by lighting the first lighting fixture 71 in the second interval, the bed surface illuminance in the head region Rla can be ensured to be 100 lx or more. Therefore, the user can be woken up by the lighting system 3. Thus, in the lighting system 3, the user's unpleasant feeling at the time of getting out of bed can be further suppressed.

[0159] Further, in the lighting system 3 of the present embodiment, in the first interval, the first lighting fixture 71 is turned off.

[0160] Thus, in the first interval, the first lighting fixture 71 is not lit, so light is not directly irradiated to the head of the user who is in bed 30. Therefore, the user is not easily made to get out of bed in the first interval, so the user is not easily made to feel an unpleasant feeling.

[0161] Further, in the lighting system 3 of the present embodiment, in the first interval, when the second lighting fixture 72 is lit, the maximum value of the bed surface illuminance in the head region Rla is 1 lx or more.

[0162] For example, if a user is directly irradiated with light while sleeping, the user feels an unpleasant feeling due to a sharp change in brightness.

[0163] However, according to the present embodiment, in the first interval, the space as a whole can be made to brighten to a certain degree in advance by indirect lighting without directly irradiating light to the user's head. Therefore, even if the head region Rla is gradually made to brighten in the second interval while directly irradiating light to the user's head, since the user is adapted to the light, the user does not easily feel a sharp change in brightness, and does not easily feel an unpleasant feeling.

[0164] Further, in the lighting system 3 of the present embodiment, in the second interval, in the case where only the first lighting fixture 71 is lit, the temporal maximum value of the bed surface illuminance in the head region Rla is 100 lx or more.

[0165] For example, in the second interval, if there is no lighting of the first lighting fixture 71, there is a case where the effect of waking up the user who is sleeping is insufficient.

[0166] However, according to the present embodiment, by lighting the first lighting fixture 71 in the second interval, the bed surface illuminance in the head region Rla can be ensured to be 100 lx or more. Therefore, the user can be woken up by the lighting system 3.

[0167] Further, in the lighting system 3 of the present embodiment, in the second section, the time maximum value of the bed surface illuminance in the head region Rla is 700 lx or more.

[0168] Thus, in the second section, the bed surface illuminance in the head region Rla can be ensured to be 700 lx or more. Therefore, in the lighting system 3, the user can be more reliably awakened. In particular, in the second section, by making the bed surface illuminance 700 lx or more at a time close to the time of the desired time of getting up, the awakening effect on the user can be improved.

[0169] Further, in the lighting system 3 of the present embodiment, the time during which the bed surface illuminance in the head region Rla is 700 lx or more is approximately in the range of 10 seconds to 60 seconds.

[0170] For example, if the irradiation time during which the bed surface illuminance in the head region Rla is 700 lx or more is short, the effect of awakening the user becomes small. On the other hand, if the irradiation time is long, the user feels an unpleasant feeling because of the glare.

[0171] However, according to the present embodiment, in the second section, by irradiating light of which the bed surface illuminance in the head region Rla is 700 lx or more for 10 seconds or more, the effect of awakening the user can be ensured. Further, in the second section, by irradiating light of which the bed surface illuminance in the head region Rla is 700 lx or more for at most 60 seconds, the unpleasant feeling of the user can be suppressed.

[0172] Further, the lighting system 3 of the present embodiment is provided with at least one of the sound device 61, the air blower 62, and the aroma device 63, a control device 60 that controls at least one of the sound device 61, the air blower 62, and the aroma device 63, and an operation device 40 that operates at least one of the sound device 61, the air blower 62, and the aroma device 63.

[0173] Thus, at least one of the sound device 61, the air blower 62, and the aroma device 63 can be controlled, so that a comfortable nap environment can be provided to the user.

[0174] Further, the rest room 1 of the present embodiment is further provided with one or more wall portions 1 If, the ceiling 13, and the lighting system 3 arranged around the bed 30.

[0175] Thus, by adopting a kit obtained by combining the small room (the room 10) provided with the wall portion 1 If and the ceiling 13 with the lighting system 3, the setting can be easily performed so that the bed surface illuminance, particularly the bed surface illuminance in the head region Rla, becomes the desired illuminance.

[0176] Further, in the rest room 1 of the present embodiment, the external dimensions of the rest room 1 are 1100 mm or less x 2100 mm or less x 1950 mm or less. Also, the lower limit values of the external dimensions of the rest room 1 are 600 mm or more x 1900 mm or more x 1000 mm or more.

[0177] Thus, if the rest room 1 is of such external dimensions, it is of a size that can get on an elevator, so it is easy to transport the rest room 1 in and out.

[0178] Further, the use space of the user in the room space R can be ensured, and the large-scale of the rest room 1 is suppressed to a degree that does not cause the user to feel oppressed. Specifically, the rest room 1 is set to be about 50 cm or more of the shoulder width of a person, and further set so that a person of 190 cm in height can lie down, and further set to be about 90 cm or more of the sitting height of a person. Thus, a space in which a person can sleep on his or her back can be ensured.

[0179] Further, the rest room 1 of the present embodiment further has a moving unit.

[0180] Thus, a movable rest room 1 that can freely move can be provided.
