Description

  The present invention relates to a bedroom light awakening system that awakens a user sleeping in a bedroom by light irradiation.

  In recent years, various techniques for improving the sleeping environment in the bedroom have been proposed, and as one of them, techniques for comfortably waking up a sleeping user have been improved. For example, in the alarm device of Patent Document 1, the lighting that brightens the room as morning arrives, the video device that projects the video so that the morning scenery can be seen through the window, and the sound that generates the chirping of a small bird telling the morning The apparatus has a generator and an air conditioner that exhales air having a comfortable temperature, and each of the devices is controlled to be able to get up comfortably.

However, since the technique of the above-mentioned patent document 1 changes the indoor environment itself, when a plurality of people are sleeping in the same bedroom, there arises a disadvantage that a person other than the person who wants to wake up also wakes up. In this case, an unpleasant sensation occurs for a person (a person in the room) who is awakened earlier than the desired time. In the above-mentioned Patent Document 1, there is a description that “a gentle stimulus is sufficient, so there is no risk of inconvenience to the roommate”, but the influence of adjusting the indoor environment extends to all persons in the bedroom. Therefore, it seems that the influence on the roommate is inevitable. In order to reduce the influence on the roommates, it is better to weaken the illuminating light and the chirping sound of the bird, but this is considered to impair the alarming effect of the person who originally wants to get up.

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a schematic configuration of a bedroom provided in a house. This bedroom is also used as a home theater, and in addition to sleeping in the bedroom, various images such as movies and video images can be viewed. 1A is a plan view of the bedroom 10 and FIG. 1B is a front view of the bedroom 10.

  In FIG. 1, two beds 11 and 12 are installed side by side in a bedroom 10. A setting device 13 having a setting function of an alarm timer is installed on the wall surface of the bedroom 10. However, in addition to being installed on the wall surface, the setting device 13 may be provided on the headboards 11a and 12a of the beds 11 and 12, the night table (not shown) installed between the beds 11 and 12, and the like. good.

  Further, a projector device 15 that is a projection type video device is attached to the wall surface on the headboards 11a and 12a side, and a screen 16 is attached to the opposite wall surface. A video signal is input to the projector device 15 from a video reproduction device (not shown) or a personal computer, and a video is projected and output based on the video signal. In addition, a speaker device 18 is attached to the wall surface of the bedroom 10.

  When watching a movie or the like in the bedroom 10, the projector device 15 is operated to project an image on the screen 16. In this case, as shown in the figure, the projected image is projected so as to cross the bedroom 10 so that the user can watch a movie or the like while relaxing on the beds 11 and 12.

  Further, the projector device 15 has an image projection function for projecting an image of a movie or the like on the screen 16 as described above, and also has an awakening function (light awakening function) for waking up a user sleeping on the beds 11 and 12. . Here, when performing light awakening, as shown to (a) of FIG. 2, the optical axis direction of the projector apparatus 15 is changed, and light is irradiated toward the downward direction. Thereby, light is irradiated toward the head of the user who is sleeping, and the user can be awakened (waken up) by the light.

  In this embodiment, in particular, the user sleeping on the two left and right beds 11 and 12 can be individually awakened, and the light irradiation range of the projector device 15 is shown in FIGS. ) And (d) as appropriate. In the case of (b), the bed 11 is irradiated with light, in the case of (c), the bed 12 is irradiated with light, and in the case of (d), the bed 11 and the bed 12 are irradiated with light. The Although any configuration can be applied as a configuration in which the light irradiation range of the projector device 15 is variable, in the present embodiment, the light irradiation range is variable using a diaphragm device.

  Next, the configuration of the projector device 15 will be described with reference to FIGS. 3 and 4. 3A and 3B are perspective views showing the configuration of the projector device 15, and FIG. 4 is a cross-sectional view taken along line AA in FIG.

  The projector device 15 includes a bracket 21 that is fixed to the wall surface of the bedroom 10 and a projector main body 22 that includes a projection mechanism such as an image generation element and a projection lens, and can swing up and down at the tip of the bracket 21. A projector main body 22 is attached to the projector. The bracket 21 has an upright portion 23 that stands up indoors, and a connecting portion 24 that is connected to the projector main body 22 is provided at the tip of the upright portion 23. A through hole 25 is formed at the center of the connecting portion 24, and an internal tooth 26 is formed on a circle that is coaxial with the through hole 25.

  Further, the projector body 22 is provided with a connected portion 31 to be connected to the connecting portion 24 of the bracket 21, and the connected portion 31 has a through hole 32 formed at the center thereof, and the through hole thereof. Three pinion gears 33 are provided so as to surround 32.

  The bracket 21 and the projector main body 22 are coupled, and the shaft 35 is inserted into the through holes 25 and 32, so that the projector main body 22 can swing with respect to the bracket 21. At this time, the internal teeth 26 on the bracket 21 side and the pinion gear 33 on the projector body 22 side mesh with each other, and the angle of the projector body 22 can be adjusted by rotating the pinion gear 33 in either the forward or reverse direction. It has become. Reference numerals 36 a and 36 b are stoppers for defining the swing range of the projector main body 22.

  The projector body 22 incorporates an angle adjustment actuator, and its configuration will be briefly described with reference to FIG. That is, one of the three pinion gears 33 is a power gear, and two are free gears. The power gear rotates by driving the motor unit 37. The motor unit 37 includes an armature 37a, a worm gear 37b, and a helical gear 37c. In addition, the motor unit 37 is provided with a position detection element 38 such as a Hall element, and the angular position of the projector main body 22 is adjusted while referring to the detection result of the position detection element 38.

  In the configuration described above, the angle adjustment actuator is built in the projector main body 22, but it is also possible to incorporate the actuator in the bracket 21 instead. Further, as the configuration of the angle adjustment actuator, any configuration other than the above can be applied.

  By the way, the light irradiation for alarming by the projector device 15 is performed according to the wake-up time for the wake-up target person specified by the user. At this time, the optical axis adjustment, the light irradiation range setting, and the illuminance adjustment of the projector device 15 are performed by a controller configured using a known microcomputer or the like. FIG. 5 shows an outline of the electrical configuration of the present system. In the bedroom 10, the installation location of the controller 41 is arbitrary, but is provided integrally with the setting device 13, for example.

  Here, when the user performs an input operation of the setting device 13, a wake-up time is set for each user (user A, B) who goes to bed separately in each bed 11, 12, and the wake-up time information is input to the controller 41. Is done. The controller 41 executes control of the angle adjustment actuator of the projector device 15 and light irradiation adjustment based on the wake-up time information for each user. At this time, the controller 41 variably adjusts the light illuminance (intensity of irradiation light) so that the user can wake up comfortably. Specifically, light irradiation to the user is started from a predetermined time before the wake-up time set by the user. Then, the light illuminance is gradually increased after that, and the illuminance adjustment is performed so that the user just wakes up at the wake-up time.

  Further, the setting device 13 outputs a wake-up stop signal (reset signal) according to the user's input operation, and the controller 41 stops the light irradiation by the projector device 15 based on the input of the wake-up stop signal.

  In addition, the controller 41 performs the optical axis adjustment of the projector device 15 by the angle adjustment actuator after the user goes to bed when the alarm by the projector device 15 is set in the next morning. As an example, in the present embodiment, the optical axis of the projector device 15 is adjusted by mode switching, and the optical axis is adjusted in a substantially horizontal direction in a video viewing mode in which a video is projected during movie viewing or the like ( In the awakening mode in which light irradiation is performed when the user wakes up, the optical axis is adjusted downward (see FIG. 2). At this time, it is preferable to check the user's sleep based on the fact that the lighting in the bedroom 10 is turned off and each time information, and to adjust the optical axis after the sleep check.

  In addition, the user's sleep state may be determined based on a human body sensor or the like, and the optical axis adjustment (mode change from the video viewing mode to the awakening mode) may be performed according to the determined user's sleep state. good. In this case, it is possible to prepare for the light awakening of the next morning, triggered by the user's sleep state. The human body sensor may be a wearable sensor that can be worn on the user's arm or the like, and a detection signal of the human body sensor is input to the controller 41. The controller 41 determines a sleep state based on biological information such as a pulse, body movement, skin temperature, and skin potential measured by a human body sensor.

  FIG. 6 is a time chart showing an alarming operation by the projector device 15. Here, it is assumed that the wake-up time of the user A sleeping in the bed 11 is AM 7:00, and the wake-up time of the user B sleeping in the bed 12 is AM 8:00.

  In FIG. 6, when it becomes AM6: 30 30 minutes before the wake-up time of the user A, the light irradiation on the user A side is started. Thereafter, the illuminance adjustment is performed so that the intensity of irradiation light is maximized at the actual wake-up time (AM 7:00). Then, when the wake-up time (AM 7:00) passes and a wake-up stop signal is input to the controller 41 in accordance with the user's input operation, the light irradiation on the user A side is stopped thereafter.

  Even if the alarm stop signal is input, the user does not always occur immediately. Further, even if the user wakes up, it may be possible to prepare to wake up thereafter. Therefore, the light irradiation by the projector device 15 is stopped after a predetermined time has elapsed after the input of the alarm stop signal. However, the configuration in which the light irradiation is automatically stopped by the alarm stop signal is arbitrary, and the light irradiation state may be continued as it is after the user gets up. Irrespective of the wake-up stop signal, it is also possible to adopt a configuration in which light irradiation is automatically stopped at a timing when a predetermined time has elapsed from the wake-up time.

  Moreover, when it becomes AM7: 30 30 minutes before the wake-up time of the user B, the light irradiation on the user B side is started. Thereafter, the illuminance adjustment is performed so that the intensity of the irradiated light is maximized at the actual wake-up time (AM 8:00). Then, when the wake-up time (AM 8:00) has passed and a wake-up stop signal is input to the controller 41 in accordance with the user's input operation, the light irradiation on the user B side is stopped thereafter.

  FIGS. 7 and 8 are schematic diagrams showing actual light irradiation states to the users A and B sleeping on the beds 11 and 12.

  FIGS. 7A and 7B show a process in which the light illuminance on the user A side gradually increases before the wake-up time. This is a period of AM 6:30 to 7:00 in the case of FIG. Indicates the state. (C) shows a state in which the light illuminance on the user A side becomes maximum after the wake-up time, and the user A wakes up in this state. On the user B side, light irradiation is not performed through (a), (b), and (c) of FIG. Therefore, the user B does not get up with the user A (that is, gets up before the original wake-up time).

  On the other hand, FIG. 8 shows a case where the users A and B are woken up at the same time. 8A and 8B show a process in which the light illuminances on both sides of the users A and B gradually increase before the wake-up time, and FIG. 8C shows the light illuminances on both sides of the users A and B after the wake-up time. Indicates the maximum state. In the state (c), both the users A and B get up.

  According to the embodiment described in detail above, since light irradiation is performed only to a specific user (sleeping person) at the wake-up time specified by the user, when a plurality of people are sleeping in the same bedroom, Only those who want to wake up can be awakened individually. As a result, it is possible to realize an awakening that is comfortable for each person when a plurality of persons are sleeping in the bedroom 10.

  Since the projector device 15 capable of projecting an image is used as the light source means, a movie can be enjoyed in the bedroom 10 and a comfortable awakening can be realized by using the projector device 15.

  Since the light irradiation by the projector device 15 is started before the wake-up time, and the intensity of the irradiating light is gradually increased so that the intensity of the irradiating light is maximized when the wake-up time is reached after that, the user desires The sleep depth can be gradually reduced until the wake-up time is reached, and the wake-up target person can be awakened comfortably at the wake-up time. Therefore, comfortable awakening (light awakening) can be realized.

  Since the optical axis direction of the projector device 15 is changed between the video viewing mode and the awakening mode, the projector device 15 is used for watching movies and the like, and the projector device 15 is used for awakening by changing the mode. Can be used properly.

  It is also possible to change the mode of light irradiation when performing light awakening as follows. For example, the sleep state (sleep depth or the like) of the wake-up target person is determined using measurement information such as a biological sensor, and the intensity of irradiation light from the projector device 15 is adjusted according to the sleep state. In this case, the intensity of the irradiation light from the projector device 15 may be adjusted according to the correlation between the wake-up time of the person to wake up and the sleep state. Specifically, if the sleep depth remains deep even when the wake-up time is near, the intensity of the irradiation light will be increased, and conversely, if the sleep state is close and the sleep state is sufficiently shallow, Do not increase the strength any further. According to this configuration, by performing light irradiation according to the sleep state, it is possible to eliminate the inconvenience that the user wakes up before the wake-up time or cannot wake up comfortably at the wake-up time. . Therefore, comfortable awakening can be realized.

  In the above embodiment, the intensity of the irradiation light by the projector device 15 is maximized after the wake-up time of each user, but this is changed, and the projector device 15 flashes light (flash light) after the wake-up time. ). In this case, the user feels more dazzled by the flashing light, and thus can be surely awakened.

  In the above embodiment, the projector apparatus 15 having the angle adjustment actuator is used and the optical axis is adjusted by the operation of the angle adjustment actuator. However, this configuration is changed. For example, it is possible to adjust the optical axis by providing a reflector in front of the projector device 15 and adjusting the angle of the reflector. The angle adjustment mechanism of the reflecting plate may be either a manual type or an electric type, but is preferably electric and may be automatically adjusted by the controller 41.

  In the above embodiment, the configuration in which the setting device 13 is installed on the wall surface of the bedroom 10 or the headboard of the beds 11 and 12 has been described. However, the setting device 13 can be changed to a portable terminal that can be arbitrarily carried by the user. It is also possible to incorporate functions. In this case, the portable terminal and the projector device 15 exchange information by wireless communication.

  A speaker provided in the bedroom 10 may be used together with a sound alarm. However, in this case, since it may be difficult for the two users to wake up individually by voice alarm, a speaker is installed near the user's head on the bed, and the speaker is activated for each user. And good.

(Second Embodiment)
In the above embodiment, the projector device 15 individually wakes up (wakes up) the user's head by irradiating the head of the user. It is assumed that the alarm video software is reproduced and the reproduced video is projected onto the user's head by the projector device 15 to wake up (wake up) the user individually. In this case, a plurality of wake-up video software is registered in a memory (such as a hard disk) of the video playback device, and the video software is selectively played back. Alternatively, a storage medium in which the alarm video software is stored is set in the video playback device and played back.

  That is, as shown in FIG. 9, the playback video of the video playback device 45 (the playback video of the alarm video software) is sent to the projector device 15, and the projector device 15 projects the video onto the beds 11 and 12. At this time, there is only one video software to be played back, but the video on the beds 11 and 12 is such that brightness and darkness are individually set on the bed 11 side and the bed 12 side (P1, in the figure). P2). Wake-up time information and the like are appropriately input from the setting device 13 to the video playback device 45.

  The wake-up video software further determines the difference between the wake-up times of the two users A and B (the beds 11 and 12 side), depending on whether the user wakes up first or the two users wake up at the same time. It is set differently according to. Also, the setting is made in accordance with the difference in brightness (glare) of the reproduced video by the video software.

For example, considering the wake-up pattern of the users A and B, the following video software is prepared.
(1) Video software (title name: “A + 60 minutes”) used when user A wakes up first, user B wakes up later, and the deviation time is 60 minutes.
(2) Video software (title name: “B + 30 minutes”) that is used when user B gets up first and user A wakes up later and the time difference is 30 minutes.
(3) Video software used when the users A and B get up at the same time (title name: “A and B”).
(4) Video software (title name: “A only”) used when only user A gets up.

  Before going to bed, the user sets the wake-up time of the person who wakes up the next morning first (when two people are at the same time) to the setting device or the like, and also uses video software (for example, the above (1) described above) (Any one of (4)) is set in the video playback device 45. And it goes to bed in the beds 11 and 12. As a result, in the next morning, the set video software is reproduced at a desired time, and the user wakes up individually during the reproduction process.

  As an example, a case where the user gets up using the video software with the title name “A + 60 minutes” will be described with reference to FIG. In FIG. 10, it is assumed that user A's wake-up time is AM 7:00 and user B's wake-up time is AM 8:00. In FIG. 10, the video pattern in the periods T1 to T4 is also shown below the time chart.

  In FIG. 10, when it becomes AM 6:30 30 minutes before the wake-up time of the user A, the reproduction of the wake-up video software starts. At this time, the image pattern is “T1” in the figure, and the user A side is a light image and the user B side is a dark image. In the period T1, a scene that gradually becomes bright is projected as a playback image on the user A side. Thereafter, when the user A wakes up (AM7: 00), the video pattern becomes “T2” in the figure, and the user A side remains a bright video with the maximum illuminance and the user B side remains a black video. Thereby, the user A gets up.

  After that, the video software continues to be played, and when it becomes AM7: 30 30 minutes before the wake-up time of user B, the video pattern becomes “T3” in the figure, the user A side remains a bright video, and the user B side The image is faint. In the period T3, a scene that gradually becomes bright is projected as a playback video on the user B side. Thereafter, when the user B wakes up (AM8: 00), the video pattern becomes “T4” in the figure, and both the user A side and the user B side take a bright video with the maximum illuminance. As a result, the user B gets up.

  As described above, according to the second embodiment, similarly to the first embodiment, when a plurality of persons are sleeping in the bedroom 10, it is possible to realize a comfortable awakening for each person.

  Further, since the video image reproduced by the video image reproduction device 45 is projected onto the person to be woken up by the projector device 15, the light awakening is performed. Therefore, an adjustment device (including a controller) for adjusting the irradiation range and irradiation intensity of the irradiation light. ) Or mechanism becomes unnecessary. Therefore, individual awakening of a person sleeping in the bedroom can be realized relatively easily.

  Since a plurality of video software to be played at the time of light awakening is prepared individually according to the wake-up sequence of a plurality of users (wake-up subjects) and the time difference between the wake-up times, the above-mentioned individual awakening may be performed depending on which video software is played back. This can be suitably performed.

  The video software has a scene where the playback video gradually becomes brighter (first scene) and then a scene where the maximum illuminance reaches (second scene), and the first scene is played before the wake-up time, After that, the second scene is played when the wake-up time is reached, so that the sleep depth can be gradually reduced until the wake-up time desired by the user is reached, and the wake-up target person can be awakened comfortably at the wake-up time. it can. Therefore, comfortable awakening (light awakening) can be realized.

(Third embodiment)
In the present embodiment, a structure in which a canopy that is a suspended ceiling is provided in a bedroom and light source means is incorporated in the canopy will be described. FIG. 11 shows a bed and a canopy installed in the bedroom.

  In FIG. 11, two beds 51 and 52 are installed side by side in the bedroom. The beds 51 and 52 are provided with a common headboard 53, and the headboard 53 is provided with a setting device 54 having a setting function of an alarm timer.

  A canopy 57 is installed above the beds 51 and 52 so as to be suspended from the ceiling 56. In this case, in particular, the canopy 57 is suspended by a plurality of support columns 58 and can be moved up and down by the support columns 58. A drive system for raising and lowering the canopy 57 is shown in FIG. The drive system shown in FIG. 12 is installed between the ceiling 56 and the canopy 57.

  In FIG. 12, a motor 61 as a drive source is a both output shaft type motor, and a drive mechanism is provided for each of the two left and right output shafts 62 in the figure. That is, a gear box 64 for transmitting the rotation of the output shaft 62 to two drive shafts 63 extending in a direction orthogonal to the output shaft 62 is provided at the tip of each output shaft 62. The gear box 64 has a configuration in which a bevel gear 64 a provided at the tip of the output shaft 62 and a bevel gear 64 b provided at the tip of the two drive shafts 63 are meshed with each other.

A support column 58 is provided at the center of the helical gear 67. In the above configuration, when the motor 61 rotates in the α direction in the figure, the drive shaft 63 rotates in the β direction in the figure along with the rotation, and the helical gear 67 further rotates in the γ direction in the figure. At this time, the four helical gears 67 are similarly rotated as the motor 61 is driven.

  FIG. 13 shows a cross-sectional structure at the connecting portion of the canopy 57, the column portion 58, and the helical gear 67. As shown in FIG. 13, a helical gear 67 is rotatably fixed to the upper surface of the canopy 57 by a fixing tool 68. In addition, screw grooves are formed in the inner peripheral portion of the helical gear 67 and the outer peripheral portion of the column portion 58, respectively. The upper end portion of the column portion 58 is fixed to the ceiling 56. In this case, when the helical gear 67 is rotated by the driving mechanism shown in FIG. 12, the helical gear 67 itself moves in either the vertical direction due to the rotation. At this time, the canopy 57 moves in either the vertical direction together with the helical gear 67.

  A stopper 69 as a fall prevention means is provided at the lower end of the support column 58, and the canopy 57 is prevented from falling by this stopper 69.

  On the other hand, as shown in FIG. 14, the canopy 57 is constituted by a rectangular outer frame 71 and a lattice frame 72 provided inside the outer frame 71 and having a large number of rectangular openings 73. . In addition, in the lattice frame 72, a lighting device 74 is incorporated in an opening at a specific position among the many openings 73. For example, one lighting fixture 74 is provided for each of the beds 51 and 52 (two in total), and each of the lighting fixtures 74 individually irradiates a user sleeping on the bed 51 or 52. Is called.

  FIG. 15 is a diagram showing a cross-sectional structure of the canopy 57 at a site where the lighting fixture 74 is incorporated. As shown in FIG. 15, a cylindrical guide portion 75 is provided in the opening 73 of the lattice frame 72 so as to penetrate in the vertical direction, and a lighting fixture 74 is disposed inside the guide portion 75. . The inner peripheral surface of the guide portion 75 is mirror-finished. The guide portion 75 imparts directivity to the light irradiated by the lighting fixture 74 and suppresses the diffusion of the irradiated light. In addition, a human detection sensor 76 is provided on the outer peripheral portion of the guide portion 75, and the presence or absence of a person sleeping on each of the beds 51 and 52 is detected by the human detection sensor 76. When the canopy 57 moves up and down, the lighting fixture 74 also moves up and down together.

  FIG. 16 is a diagram illustrating the configuration of the front surface portion of the setting device 54. On the front part of the setting device 54, a time display unit 81 for displaying the current time and an alarm time (alarm time), a time operation unit 82 for operating the set time, and two left and right beds 51, 52 are provided. A user-designated switch 83 for selecting one of the beds (users A and B), an alarm switch 84 for turning on / off the alarm, a lighting switch 85 for turning on / off the reading light, and a canopy A lift switch 86 for moving up and down 57 and a speaker 87 are provided. In the setting device 54, when the user performs an input operation, the wake-up time is set for each user (users A and B) who goes to bed separately in the beds 51 and 52. Further, the canopy 57 is raised or lowered by the raising / lowering button operation of the raising / lowering switch 86, and the illumination height is changed accordingly.

  FIG. 17 is a schematic diagram showing an electrical configuration of the above-described bedroom system. The controller 91 is a control device configured using a known microcomputer or the like, and various setting information (such as wake-up time information and up / down command information of the canopy 57) by the setting device 54 is input to the controller 91. At the same time, detection signals from the human detection sensor 76 are sequentially input. The installation location of the controller 91 is arbitrary, but is provided integrally with the setting device 54, for example.

  The controller 91 performs light irradiation by the lighting fixture 74 based on the wake-up time information for each user set by the setting device 54. At this time, the controller 91 performs variable adjustment of light illuminance so that the user can wake up comfortably. Specifically, light irradiation to the user is started from a predetermined time before the wake-up time set by the user. Then, the light illuminance is gradually increased after that, and the illuminance adjustment is performed so that the user just wakes up at the wake-up time.

  The specific wake-up operation in the present embodiment is similar to FIG. 6 described above, and here, the wake-up operation will be described with reference to FIG. 6 again. It is assumed that the wake-up time of the user A sleeping on the bed 51 is AM 7:00 and the wake-up time of the user B sleeping on the bed 52 is AM 8:00.

  In FIG. 6, when it becomes AM6: 30 30 minutes before the wake-up time of the user A, the light irradiation on the user A side is started. Thereafter, the illuminance adjustment is performed so that the intensity of irradiation light is maximized at the actual wake-up time (AM 7:00). Then, when the wake-up time (AM 7:00) passes and a wake-up stop signal is input to the controller 91 in accordance with the user's input operation, the light irradiation on the user A side is stopped thereafter.

  Even if the alarm stop signal is input, the user does not always occur immediately. Further, even if the user wakes up, it may be possible to prepare to wake up thereafter. Therefore, the light irradiation by the lighting fixture 74 is stopped after a predetermined time has elapsed after the input of the alarm stop signal. However, the configuration in which the light irradiation is automatically stopped by the alarm stop signal is arbitrary, and the light irradiation state may be continued as it is after the user gets up.

  Moreover, when it becomes AM7: 30 30 minutes before the wake-up time of the user B, the light irradiation on the user B side is started. Thereafter, the illuminance adjustment is performed so that the intensity of the irradiated light is maximized at the actual wake-up time (AM 8:00). Then, when the wake-up time (AM8: 00) passes and a wake-up stop signal is input to the controller 91 in accordance with the user's input operation, the light irradiation on the user B side is stopped thereafter.

  As described above, according to the third embodiment, similarly to the first embodiment and the like, when a plurality of people are sleeping in the bedroom 10, it is possible to realize comfortable awakening for each person.

  Moreover, since the illumination device 74 installed on the canopy 57 is used so that the user sleeping on the beds 51 and 52 can be exposed to the irradiation light from above, the sleeping user can be surely awakened.

  Since the canopy 57 can be moved up and down, for example, it is possible to give the user a sense of security by lowering the canopy 57 and using it as a ceiling. Therefore, the comfort of sleep can be enhanced.

  In the canopy 57, an electric or manual screen is installed at the end of the outer frame 71 (the end of the user's feet on the bed), and a video or the like is projected using the screen. Is possible. In this case, a projector device is installed on the headboard 53 side of the beds 51 and 52, and an image from the projector device is projected on the screen. In the case of having a configuration for projecting an image on the screen in this way, a healing image, a schedule for the day, and the like can be projected on the screen in conjunction with the light awakening by the lighting device 74 when waking up. Thereby, a comfortable wake-up can be realized. In this case, in consideration of the detection result of the human detection sensor 76, the projector may be projected on the condition that it is detected that a person is sleeping on the bed.

(Fourth embodiment)
In the present embodiment, the individual awakening of the user is realized in a bedding device in which a plurality of people can sleep simultaneously. 18 and 19 show specific examples in which an individual awakening function is added to a double bed. FIG. 18 is a diagram showing the configuration of the entire bed, and FIG. 19 is a front view showing the configuration of the headboard (viewed from the user on the bed, especially about the portion above the pillow on the bed. Shown).

  In FIG. 18, a bed 101 has a size sufficient for two adults (users A and B) to sleep side by side, and a headboard 102 is provided on the head side. The head board 102 is provided with an overhang portion 103 so as to overhang the user's head, and a plurality of illumination lamps 104 are attached to the lower surface of the overhang portion 103. Each of the illumination lamps 104 is provided in the downward direction, so that the user's head can be irradiated with light. The illumination lamp 104 is made of an LED lamp, for example, and has a directivity. The plurality of illumination lamps 104 correspond to light awakening light source means.

  As shown in FIG. 19, the illumination lamps 104 are provided in two systems so as to correspond to the left and right users sleeping on the bed 101, and each has seven lamps corresponding to the users A and B (see FIG. 18). It is attached one by one. The illumination lamp 104 can be individually turned ON / OFF and illuminance adjustment for each of the left and right systems. Each illumination lamp 104 has a configuration that can freely swing in any direction, and the configuration is shown in FIGS.

  The illumination lamp 104 has a lamp main body 105 having a light source and a base body 106 attached to the head board 102 side, both of which are rotatably connected by a shaft pin 107. Further, the base body 106 is rotatable around the longitudinal center line thereof, and a friction spring 108 is provided at the end portion on the headboard side. According to this configuration, in the illumination lamp 104, the base body 106 can rotate around the center line, and the lamp main body 105 can swing with respect to the base body 106. Therefore, the illumination direction can be manually adjusted in the direction desired by the user, and it is easy to use even when used as reading illumination. Note that the angle in the illumination direction is held by the friction spring 108.

  Two setting devices 111 and 112 are embedded in the headboard 102 for each user (each system), and the front portions of the setting devices 111 and 112 are exposed to the bed side. On the front part of the setting devices 111 and 112, a time display unit for displaying the current time and the alarm time (alarm time), a time operation unit for operating the set time, and reading light and alarm ON / OFF A changeover switch for switching is provided. The changeover switch has a three-position switching type switch piece. By the switch piece, (1) Reading light ON & alarm OFF, (2) Reading light OFF & alarm OFF, (3) Reading light OFF & alarm ON. Switching between three states is possible.

  Further, two controllers 113 and 114 corresponding to the two setting devices 111 and 112 are embedded in the headboard 102. The controllers 113, 114 execute light irradiation by the illumination lamp 104 based on the wake-up time information for each user set by the setting devices 111, 112. At this time, the controllers 113 and 114 perform variable adjustment of light illuminance so that the user can wake up comfortably. Specifically, light irradiation to the user is started from a predetermined time before the wake-up time set by the user. Then, the light illuminance is gradually increased after that, and the illuminance adjustment is performed so that the user just wakes up at the wake-up time.

  In the bed 101, a dedicated long pillow 121 is used. FIG. 21 is a plan view showing the configuration of the long pillow 121. The long pillow 121 is shared by users A and B, and two sensor units 122 are embedded in the pillow. The sensor unit 122 outputs an electrical signal of a predetermined level when the user puts his head on the pillow, and has a configuration in which a plurality of sensor elements 122a are connected in series. This sensor unit 122 corresponds to a human detection means. As the sensor element 122a, a pressure-sensitive sensor, a sound detection sensor, or the like can be applied.

  The long pillow 121 is provided with a signal line 123 for outputting a sensor signal for each system, and a plug plug 124 is provided at the tip of the signal line 123. By inserting the insertion plug 124 into a predetermined insertion port of the bed 101, the detection signal of the sensor unit 122 is taken into the controllers 143 and 144 on the bed side. The controllers 143 and 144 detect the head position of the user sleeping on the bed 101 based on the detection signal of the sensor unit 122, and execute light irradiation according to the head position.

  The specific wake-up operation in the present embodiment is similar to FIG. 6 described above, and here, the wake-up operation will be described with reference to FIG. 6 again. Of the two users A and B sleeping on the bed 101, it is assumed that the wake-up time of user A is AM 7:00 and the wake-up time of user B is AM 8:00.

  In FIG. 6, when it becomes AM6: 30 30 minutes before the wake-up time of the user A, the light irradiation on the user A side is started. Thereafter, the illuminance adjustment is performed so that the intensity of irradiation light is maximized at the actual wake-up time (AM 7:00). Then, when the wake-up time (AM 7:00) passes and a wake-up stop signal is input to the controller 141 in accordance with the user's input operation, the light irradiation on the user A side is stopped thereafter.

  Even if the alarm stop signal is input, the user does not always occur immediately. Further, even if the user wakes up, it may be possible to prepare to wake up thereafter. Therefore, the light irradiation by the lighting fixture 74 is stopped after a predetermined time has elapsed after the input of the alarm stop signal. However, the configuration in which the light irradiation is automatically stopped by the alarm stop signal is arbitrary, and the light irradiation state may be continued as it is after the user gets up.

  Moreover, when it becomes AM7: 30 30 minutes before the wake-up time of the user B, the light irradiation on the user B side is started. Thereafter, the illuminance adjustment is performed so that the intensity of the irradiated light is maximized at the actual wake-up time (AM 8:00). Then, when the wake-up time (AM8: 00) passes and a wake-up stop signal is input to the controller 141 in accordance with the user's input operation, the light irradiation on the user B side is stopped thereafter.

  As described above, according to the fourth embodiment, similarly to the above-described embodiments, when a plurality of people are sleeping in the bedroom 10, it is possible to realize a comfortable awakening for each person.

  Since the long pillow 121 used on the bed incorporates the sensor unit 122 that detects the position of the user's head, the irradiation light can be reliably applied to the head of the person sleeping on the bed.

(Fifth embodiment)
In this embodiment, a light awakening function is added to the pillow used on the bed, and the user is awakened by the light awakening. FIG. 22 is a partially broken perspective view showing the entire configuration of the alarm pillow 160 having a light awakening function.

  In the alarm pillow 160 of FIG. 22, the pillow body 161 is molded from a foaming low-resilience resin (for example, polyurethane open-cell foam material), and the shape in plan view is a horizontally long rectangle. . One side (upper surface in the figure) of the pillow body 161 is a head-mounted portion 162, and the head-mounted portion 162 has a shape in which the center is gently recessed. A concave portion 163 is formed on the bottom surface side of the pillow body 161 so as to extend in the longitudinal direction. The pillow body 161 is formed with a plurality of through holes 164 that allow the head-mounted portion 162 and the recess 163 to communicate with each other. The through holes 164 are provided, for example, at even intervals and are provided in parallel to each other so as to face the same direction.

  A light source device 166 that emits light inside the pillow body 161 is provided in the recess 163 of the pillow body 161. The light source device 166 is manufactured in a size that can be accommodated in the recess 163, and the light source device 166 is assembled to the pillow body 161 in a state of being placed on the bottom plate 167. Detailed configurations of the light source device 166 and its peripheral members will be described below.

  The bottom plate 167 is formed in the same shape and size as the opening of the recess 163, and the reflecting mirror 168 is fixed on the bottom plate 167. The reflecting mirror 168 has a long plate shape, and its short direction is curved in an arc shape. The reflecting mirror 168 also functions as a light collector. On the bottom plate 167, a pair of lamp sockets 170 are provided on both sides in the longitudinal direction of the reflecting mirror 168, and a fluorescent lamp 171 is attached between the lamp sockets 170. In this case, when the fluorescent lamp 171 emits light, the light is reflected upward by the reflecting mirror 168. At that time, light is emitted above the pillow (on the head-mounting portion 162 side) through the through-hole 164 of the pillow body 161. Note that a light source protection member 172 such as a wire for protecting the fluorescent lamp 171 is attached to the reflecting mirror 168.

  On the bottom plate 167, a setting device 180 having an alarm timer setting function and the like is provided. One surface (setting operation surface) of the setting device 180 is exposed to the outside from the pillow body 161, and on the setting operation surface, a time display unit 181 for displaying the current time and the alarm time (alarm time), and a setting time A time operation unit 182 for performing the above operation and a changeover switch 183 for switching ON / OFF of the alarm are provided.

  In addition, a scent generating device 185 is provided on the bottom plate 167. In this case, the scent generated from the scent generator 185 provides a mental stability effect during sleep. It can also be expected to reduce stress and promote relaxation.

  Also in this embodiment, as described in each of the above embodiments, the controller (not shown) in the setting device 180 causes the light source device 166 to emit light before the wake-up time (for example, 30 minutes before the wake-up time). It is preferable to gradually increase the intensity of the irradiation light so that the intensity of the irradiation light becomes maximum when the irradiation is started and then the wake-up time is reached. Thereby, the sleep depth can be gradually reduced until the user's desired wake-up time is reached, and the wake-up target person can be awakened comfortably at the wake-up time.

  As described above, according to the fifth embodiment, the alarm pillow 160 incorporating the light source device 166 is used, and the light source device 166 is caused to emit light according to the wake-up time so that the irradiation light is emitted to the outside. Individual awakening by irradiation light can be realized. In this case, since the sleeper's head is placed on the alarm pillow 160, the configuration in which light is directly irradiated from the alarm pillow 160 is considered to be an effective means for waking up the user.

  In the alarm pillow 160, since the through-hole 164 (light transmission hole) is opened in the head mounting portion 162, the irradiation light is basically emitted only upward, and another person (same roommate) sleeps on the side. Even if it is, the influence on the other person can be reduced.

  It is good also as a structure which installs a human detection sensor in said alarm pillow 160, and performs light irradiation based on the detection result of the human detection sensor. Thereby, light irradiation is performed only when the alarm pillow 160 is actually used, and unnecessary light irradiation can be prevented from being performed.

  The alarm pillow 160 may be a long pillow that can be shared by a plurality of people. In this case, it is set as the structure which incorporates several light source devices, and is set as the structure which can irradiate light individually.

  In each of the above embodiments, in addition to awakening (wakening) by irradiation light, awakening (wakening) by voice or vibration is performed. In this case, in order to perform individual awakening of the user, the above-described optical awakening method is desirable. However, when the user is not awakened or the like, it is preferable to wake up by sound or vibration as appropriate.
