Description

  The present invention relates to a building blind control system.

  In a building such as a house, when a blind device having a blind curtain is provided for a window on the wall, outside light such as sunlight is taken into the room from the window by moving the blind curtain to the daylighting state, and is blocked. By shifting to the state, the outside light is not taken into the room. For example, Patent Document 1 describes a configuration of a blind device that shifts a blind curtain to a daylighting state in accordance with a person's wake-up time. According to this configuration, the room illuminance at the time of awakening is sufficiently secured, so that the comfort of waking up is given to a person who gets up. Moreover, in this structure, the lighting fixture with a ceiling is provided, and it is possible to brighten the room also with the lighting fixture.

JP 2005-310438 A

  However, in Patent Document 1, when the outdoors is dark, it is not possible to take in outside light indoors even if the blind curtain is shifted to the daylighting state. In this case, even if a lighting fixture with a ceiling is turned on, the room is only brightened, and the atmosphere is not such that outside light is inserted into the room. Therefore, there is room for improvement with respect to a configuration in which the indoor atmosphere is changed by the blind device.

  The main object of the present invention is to appropriately create an atmosphere in which external light is taken into a building space.

  In order to solve the above-mentioned problem, a first invention includes a blind curtain having a plurality of slats and provided in an opening of a building, slat driving means for opening and closing the slats, and provided in the slats. A light emitting means capable of emitting light in an internal space, an external light quantity information acquiring means for acquiring external light quantity information correlated with an external light quantity in the outdoors, the slat driving means based on the external light quantity information acquired by the external light quantity information acquiring means, and And a control means for controlling the light emitting means.

  According to the first invention, in the configuration in which the light emitting means provided on the slat of the blind curtain emits light, the slat driving means and the light emitting means are controlled based on the external light quantity information each time, so that it matches the outdoor brightness. Can change the indoor environment. In addition, this configuration can create a situation similar to or similar to the case where external light is introduced through the blind curtain, unlike the case where a lighting fixture generally provided on the ceiling or the like is turned on. As a result, an atmosphere in which external light is taken into the building space can be appropriately created.

  In the second invention, the outside light quantity information acquisition means uses the outside light quantity information as the outside light quantity information as an actual outside light quantity that is an actual outside light quantity in the outdoors and the slats in a predetermined open state, thereby allowing the inside of the building to pass through the blind curtain. Means for calculating at least one of the external light quantities that can be introduced into the space.

  According to the second invention, as the external light amount information, the actual external light amount outdoors and the external light amount introduced into the building space when the slat is opened are acquired. Suitable control can be realized after grasping the introduction status of the external light quantity into the space.

  When the actual light amount is calculated as the external light amount information, the control unit is configured to match the light amount in the building space with the actual light amount or a predetermined non-reference light amount. It is preferable to control the light emitting means. If the configuration matches the actual light intensity, for example, it can create an atmosphere that improves the sunlight when the space in the building is bad, and avoids a temperature rise due to solar radiation when the sunlight is too good. It is possible to create an atmosphere in which external light is captured. On the other hand, if the configuration matches the non-reference light amount, an atmosphere in which a predetermined external light amount is inserted through the opening regardless of the outdoor brightness can be created.

  In a third aspect of the invention, the control means performs wakefulness control by the slat driving means and the light emitting means based on each wake-up time.

  According to the third aspect of the invention, it is possible to create an atmosphere in which external light is taken in through the blind curtain in accordance with the wake-up time, so that it is possible to bring a comfortable awakening to the user.

  According to a fourth aspect of the invention, there is provided means for setting a wake-up reference non-reference light amount that serves as a reference of the external light amount at the wake-up time, and the control means includes the external light amount information acquired by the external light-quantity information acquisition means at the wake-up time. Based on the above, the light emitting means is caused to emit light when the outside light quantity is insufficient with respect to the reference outside light quantity when waking up.

  According to the fourth aspect of the invention, the amount of light necessary for awakening can be ensured in the building space regardless of the outdoor brightness. Therefore, for example, even when the amount of external light is small when it is raining compared to when it is sunny, or when the sunrise is late in the winter compared with the summer, it is possible to brighten the space in the building in the same manner when getting up.

  In a fifth aspect of the invention, the control means includes a means for setting a pre-wake-up reference non-light amount that is a reference of the external light amount in a pre-wake-up period from a predetermined time before the wake-up time to the same wake-up time, and the control means Based on the external light amount information acquired by the external light amount information acquisition unit, the light emitting unit is caused to emit light when the external light amount is insufficient with respect to the reference external light amount before waking up.

  According to the fifth invention, appropriate awakening control can be performed even before the rising time is reached. In this case, since awakening is gradually promoted from before the wake-up time, a comfortable awakening can be brought about at the wake-up time.

  According to a sixth aspect of the invention, there is provided wakefulness detection means for detecting whether or not the user is in a wakefulness state, and the control means is based on the detection result of the wakefulness detection means, in addition to the light emitting means. Causes another indoor lighting fixture to emit light.

  According to the sixth aspect, when the user does not wake up at the wake-up time, the building space can be sufficiently bright regardless of the amount of external light. That is, the user who is not awakened by the external light and the light emitted from the light emitting means can be awakened by making the user feel a stronger brightness.

  In a seventh aspect of the invention, the control means causes the light emitting means to emit light in accordance with the light shielding amount by the blind curtain when the blind curtain is in a light shielding state.

  If a person feels dazzling in the building space, such as when sunlight is directly introduced through the opening, it can be eliminated by moving the blind curtain to a light-blocking state. There is concern about the space becoming dark. In this regard, according to the seventh invention, when the blind curtain is in a light shielding state, the light emitting means emits light according to the light shielding amount by the blind curtain. The brightness of the interior space can be secured.

  In an eighth aspect of the invention, the control means calculates the light shielding amount based on the external light amount information acquired by the external light amount information acquisition means and the slat opening of the blind curtain, and based on the calculated light shielding amount. The light emitting means emits light.

  When the light emitting means emits light according to the light shielding amount by the blind curtain, it is preferable to calculate the light shielding amount based on the external light amount information and the slat opening as in the eighth invention.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings. FIG. 1 is a diagram showing a schematic configuration around the bedroom 12 of the building 10.

  As shown in FIG. 1, a building 10 such as a house is provided with a bedroom 12 as a space in the building, and a bed 15 for sleeping is installed in the bedroom 12. On the wall surface 12a of the bedroom 12, an operation panel 17 having an alarm timer setting function and the like is installed. In the bedroom 12, an indoor lighting fixture 18 is installed on the wall surface 12a and the ceiling surface 12b to brighten the entire interior of the bedroom 12.

  In the bedroom 12, a window 22 as an opening is provided on the outer wall 21 that forms the wall 12 a on the outdoor side. The window portion 22 is provided with a sash door 23 made of a glass door having a glass plate, and a shutter device 31 is provided indoors. The shutter device 31 includes a shutter curtain 32 as a blind curtain that has a plurality of slats 35 and moves up and down in a vertical direction, and a shutter case 33 that accommodates the shutter curtain 32 in a wound state. In the present embodiment, an electric shutter device is used in which the shutter curtain 32 is raised and lowered and the angle adjustment (opening and closing) of the slat 35 is performed by an electric motor or the like.

  In the shutter curtain 32, the slats 35 have a long plate shape and are connected in a state of being arranged in the vertical direction. The slat 35 is made of, for example, a non-translucent synthetic resin material. The shutter curtain 32 is provided with an angle adjustment mechanism that adjusts the slat angle. For example, the slat angle is adjusted by driving the angle adjustment mechanism by a slat drive unit 37 as a slat drive means provided in the shutter case 33. It is like that. In this case, the angles of all slats 35 are changed all at once. Further, the shutter case 33 is provided with a lifting drive unit 38 for lifting and lowering the shutter curtain 32.

  Here, details of the slat 35 will be described with reference to FIG. FIG. 2 is a diagram showing a schematic cross-sectional structure of the slat 35, in which (a) shows the slat 35 in a fully closed state, and (b) and (c) show the slat 35 in a predetermined open state. The slat 35 is provided with a shaft portion 35a as a rotation shaft so that the slat 35 can be shifted to each state shown in FIGS.

  In FIG. 2A, the longitudinal direction of the longitudinal section of the slat 35 (short direction in front view) coincides with the vertical direction. In this state, there is no gap between the slats 35 adjacent to each other in the vertical direction. There are also a few. This is the slat fully closed state. A tail portion 51 extending obliquely downward is provided at the lower end portion of the slat 35. The tail portion 51 of the upper slat overlaps the lower slat when viewed from the outdoor side, thereby shielding light in the slat fully closed state. Sexuality is enhanced.

  In addition, each slat 35 is provided with a slat LED 53 as a light emitting means on a slat side surface portion which is an indoor side (the bedroom 12 side) in the slat fully closed state. The slat LEDs 53 are provided at substantially the center of the slat 35 in the short side direction when viewed from the front, and a plurality of slat LEDs 53 are provided in the longitudinal direction when viewed from the front. The slat LED 53 emits light in a direction substantially orthogonal to a slat side surface portion that is an LED mounting surface. The slat LED 53 is attached in a state of being embedded in the slat side surface. In addition, the direction in which the slat LED 53 emits light may not be substantially orthogonal to the slat side surface.

  The slat LED 53 of each slat 35 is installed so that the horizontal installation interval (LED pitch in the horizontal direction of the same slat) is shorter than the vertical installation interval (LED pitch in two adjacent upper and lower slats). Therefore, in the LED light emitting state, it is visually recognized as if continuous light is emitted in the lateral direction, that is, in the longitudinal direction of the slat 35.

  As described above, light that is continuous in the longitudinal direction of the slats is emitted, so that even when the slats are fully closed, a gap is formed between the slats 35 in the shutter curtain 32 and external light is inserted through the gaps. It can be in such a state.

  In FIG. 2 (b), the tail side end portion (lower end portion in the slat fully closed state) of the slat 35 is the outdoor side, and the opposite end portion (upper end portion in the slat fully closed state) is The slat 35 is rotated so as to be on the indoor side, and the longitudinal cross-sectional longitudinal direction of the slat 35 is inclined by an angle θ1 with respect to the vertical direction. θ1 <90 °. In this case, a gap is formed between vertically adjacent slats 35. In the state of FIG.2 (b), the LED attachment surface of the slat 35 has faced diagonally downward by the bedroom 12 side.

  Further, in FIG. 2 (c), as in FIG. 2 (b), the tail side end portion (lower end portion in the slat fully closed state) of the slat 35 is the outdoor side, and the opposite end portion (slat fully closed). The upper end of the slat 35 is turned to the indoor side, and the longitudinal direction of the slat 35 is inclined by an angle θ2 with respect to the vertical direction. θ2> 90 °. The state of FIG. 2C is the maximum rotation state when rotating as (a) → (b) → (c), and the angle θ2 in the maximum rotation state is, for example, 110 °. . In the state of FIG. 2C, the LED mounting surface of the slat 35 faces obliquely downward on the outdoor side.

  When the slat 35 rotates as shown in FIGS. 2B and 2C, the light emission direction of the slat LED 53 is changed. Thereby, when the slat LED 53 emits light, the amount of light taken into the bedroom 12 can be adjusted even if each LED 53 is in the same light emitting state. When comparing FIG. 2B and FIG. 2C, the amount of LED light introduced indoors is larger in FIG. 2B. When the slat is open and the outdoors is bright, LED light is introduced into the bedroom 12 together with outside light.

  Next, an electrical configuration for controlling the operation of the shutter device 31 will be described with reference to FIG.

  In FIG. 3, the bedroom server 61 as a control means includes a microcomputer including a CPU and various memories, and includes a storage unit 62 and a timer 63. The storage unit 62 can store, for example, human biological information, and the timer 63 can perform time measurement according to, for example, human biological information. The bedroom server 61 is provided integrally with the operation panel 17 in the bedroom 12, for example.

  An operation panel 17, a living body sensor 65, and an external light sensor 66 are connected to the bedroom server 61. When the wake-up time is set by the user on the operation panel 17, a signal related to the wake-up time is output from the operation panel 17 to the bedroom server 61. In addition, detection signals from the living body sensor 65 and the external light sensor 66 are also sequentially output to the bedroom server 61.

  The biometric sensor 65 is biometric information detection means for detecting biometric information of a sleeping person, and is provided, for example, on a mattress or pillow of the bed 15. The biological information detected by the biological sensor 65 includes the body temperature and heart rate of a sleeping person. The bedroom server 61 determines whether a person on the bed 15 is in an awake state based on the detection signal of the biometric sensor 65. The outside light sensor 66 is attached to, for example, the surface on the outdoor side of the window 22 and serves as outside light detecting means for detecting the illuminance of outside light (light in the outdoors).

  In addition, the indoor lighting device 18 and the shutter control unit 68 are connected to the bedroom server 61. The bedroom server 61 controls the operation of the indoor lighting device 18 by outputting a command signal. The shutter control unit 68 is connected to a slat drive unit 37, a lift drive unit 38, and a slat LED 53, and the shutter control unit 68 outputs a command signal so that the slat drive unit 37, the lift drive unit 38, and the slat LED 53 are output. Drive.

  Further, a home server 69 is connected to the bedroom server 61, and the home server 69 includes a microcomputer composed of a CPU, various memories, and the like, similar to the bedroom server 61. In addition to the bedroom server 61, a toilet server and a bath server are connected to the home server 69, and a health management network is constructed by the home server 69 and other servers. The home server 69, the bedroom server 61, and other servers share biological information via the health management network. In addition to the biological information detected by the biological sensor 65, for example, a biological sensor incorporated in a wristwatch. The detected biological information is exchanged.

  In this embodiment, awakening control using the shutter device 31 is performed when the user wakes up. That is, external light is positively introduced into the bedroom 12 by this awakening control, and the bedroom 12 is brightened by the introduction of the external light so that the user can wake up comfortably. More specifically, as the external light amount information, an actual external light amount (actual external light amount La) outdoors and an external light amount (introduction that can be introduced into the bedroom 12 through the shutter curtain 32 when the slat 35 is in a predetermined open state). The possible outside light quantity Lb) is calculated, and based on these, the slat opening / closing control of the shutter curtain 32 and the light emission control of the slat LED 53 are performed.

  Hereinafter, details of the awakening control will be described in detail with reference to FIG. FIG. 4 is a flowchart showing a processing procedure of awakening control, and this processing is executed by the bedroom server 61 at a predetermined cycle. The awakening control is activated on condition that, for example, a wake-up time is set and the awakening control mode is set.

  In FIG. 4, in step S <b> 11, it is determined whether or not it is the awakening control period that is currently set based on the wake-up time. The awakening control period is a period including the period before and after the wake-up time. The previous period from the predetermined time before the wake-up time to the same wake-up time (corresponding to the first half of the wake-up time) and the subsequent stage until the predetermined time after the wake-up time. It consists of a period. For example, when the wake-up time is am 7:00, the former period is am6: 40 to am7: 00, and the latter period is am7: 00 to am7: 10.

  If it is the awakening control period, the process proceeds to step S12, where the actual actual light amount La is calculated based on the detection signal of the outside light sensor 66, and the inside of the bedroom 12 is passed through the shutter curtain 32 by opening the slat 35 in a predetermined open state. The amount of external light that can be introduced into (the amount of external light Lb that can be introduced) is calculated. Specifically, for example, a case where the shutter curtain 32 is in the state shown in FIG. 2C, that is, the case where the slat angle is θ2 (= 110 °), is introduced through the shutter curtain 32 in this state. The external light amount to be calculated is calculated based on the actual external light amount La. Incidentally, as the assumed slat open state is a smaller opening degree, the introduceable external light quantity Lb is calculated as a smaller value than the actual external light quantity La.

  Then, in step S13, it is determined whether it is before the wake-up time. And if it is before the wake-up time, it will progress to step S14 and will implement the pre-stage process for awakening preparation, and if it is after wake-up time, it will progress to step S18 and will perform the post-stage process.

  Steps S14 to S17 correspond to pre-processing. This pre-stage process is control for gradually bringing the user closer to the wake-up state before the wake-up time, and is performed before the wake-up time in order to make the user comfortably wake-up when the wake-up time is reached. Specifically, in step S14, a first reference external light amount Ref1 that is a reference of the external light amount in the preceding period within the awakening control period is set. The first reference extraneous light quantity Ref1 is an extraneous light quantity necessary for the user's awakening preparation, and is determined based on the extraneous light quantity in the early morning, assuming a sunny day in the summer of the year, for example. Note that the first non-reference light amount Ref1 may be gradually increased with the passage of time in consideration of a change in light amount with the passage of time in the preceding period.

  Thereafter, in step S15, it is determined whether or not the actual outside light amount La calculated in step S12 is greater than or equal to the first reference outside light amount Ref1. If La ≧ Ref1, the process proceeds to step S16, and if La <Ref1, the process proceeds to step S17.

  If the outdoors is sufficiently bright in preparing for awakening, La ≧ Ref1, and it is determined that the external light amount is not insufficient with respect to the first reference external light amount Ref1, and the process proceeds to step S16. In step S16, opening / closing control of the shutter curtain 32 is performed, and the interior of the bedroom 12 is gradually brightened by introducing external light. At this time, the external light introduction amount is gradually increased by gradually increasing the slat angle.

  On the other hand, in preparation for awakening, if the outdoor is still dark, La <Ref1, and it is determined that the external light amount is insufficient with respect to the first reference external light amount Ref1, and the process proceeds to step S17. In step S17, the light emission control of the slat LED 53 is performed, and the interior of the bedroom 12 is gradually brightened by the LED light. At this time, the amount of light emitted from the shutter curtain 32 is adjusted by setting the slat LED 53 to the light emitting state and gradually changing the LED light emitting direction by controlling the slat angle. When the light emission amount of the slat LED 53 can be adjusted, the LED light emission amount may be gradually increased.

  On the other hand, steps S18 to S23 correspond to a subsequent process. This subsequent processing is control for ensuring that the user is awake when the wake-up time is reached and within a predetermined time thereafter. Specifically, in step S18, a second reference extraneous light amount Ref2 is set which serves as a reference for the extraneous light amount in the latter period of the awakening control period. The second reference extraneous light quantity Ref2 is an extraneous light quantity necessary for the user's awakening completion, and is determined based on the extraneous light quantity in the early morning, assuming a sunny day in summer of the year, for example.

  Thereafter, in step S19, it is calculated whether or not the installable external light amount Lb calculated in step S12 is equal to or greater than the second reference external light amount Ref2. If Lb ≧ Ref2, the process proceeds to step S20, and if Lb <Ref2, the process proceeds to step S21.

  If the outdoors is sufficiently bright to complete the awakening, Lb ≧ Ref2, and it is determined that the external light amount is not insufficient with respect to the second reference external light amount Ref2, and the process proceeds to step S20. In step S20, opening / closing control of the shutter curtain 32 is performed to brighten the interior of the bedroom 12 by introducing external light. At this time, if the external light quantity Lb that can be introduced is substantially the same as the second reference external light quantity Ref2, the shutter curtain 32 is assumed to be in the state shown in FIG. 2C, that is, the slat assumed in the calculation of the external light quantity Lb that can be introduced. Control to an angle (θ2). Further, when the external light quantity Lb that can be introduced is excessively large with respect to the second reference external light quantity Ref2, the slat 35 of the shutter curtain 32 is controlled to the closed side (closer side than θ2) based on the excessive quantity. Good.

  Further, when the outdoor is still dark in completing the awakening, Lb <Ref2, and it is determined that the external light amount is insufficient with respect to the second reference external light amount Ref2, and the process proceeds to step S21. In step S21, light emission control of the slat LED 53 is performed to brighten the interior of the bedroom 12 with the LED light. At this time, the slat LED 53 is brought into a light emitting state, and the LED light emission direction is adjusted by controlling the slat angle, so that the shortage of the installable external light amount Lb with respect to the second reference external light amount Ref2 is compensated. Adjust the flash output. When the light emission amount of the slat LED 53 can be adjusted, the LED light emission amount may be controlled based on the shortage of the installable external light amount Lb with respect to the second reference external light amount Ref2.

  Thereafter, in step S22, based on the detection signal of the biosensor 65, it is determined whether or not the user is in an awake state (whether or not he / she has awakened). And if it is not in an awake state (step S22 is NO), it will progress to step S23 and light emission by the indoor lighting fixture 18 will be performed. As a result, the user who has not been awakened even though the wake-up time has already been awakened is urged.

  In the present embodiment, the shutter device 31 is controlled not only when waking up but also in the daytime. For example, when sunlight is directly inserted indoors and is dazzling, the glare of sunlight is avoided. While ensuring indoor brightness.

  FIG. 5 is a flowchart showing a daytime shutter control processing procedure, and this processing is executed by the bedroom server 61 in a predetermined cycle. The daytime shutter control is activated on condition that the daytime use mode is set.

  In FIG. 5, in step S <b> 31, it is determined whether or not the person is excessively dazzled by the external light introduced through the shutter curtain 32. For example, an external light amount that causes a person to feel excessive glare is set as an excessive external light amount, and it is determined whether or not the external light amount Lb that can be introduced is equal to or greater than the excessive external light amount. It is assumed that the person feels excessive glare if the installable external light quantity Lb is greater than or equal to the excess reference extra light quantity, and the person does not feel excessive glare if the introduceable external light quantity Lb is smaller than the excess reference extra light quantity. . In addition, the external light here assumes sunlight. Further, it may be determined whether or not the person feels excessive glare based on the actual outside light amount La instead of the installable outside light amount Lb.

  If the person does not feel excessive glare, the process is terminated. If the person feels excessive glare, the process proceeds to step S32. In step S32, closing control of the shutter curtain 32 is performed, and the slat 35 of the shutter curtain 32 is rotated to the closing side based on the excessive amount of glare in the external light. For example, the slat angle is controlled so that the slat 35 blocks the excess of the installable external light amount Lb based on the excessive reference external light amount.

  In step S33, the amount of light shielded by the slat 35 is calculated. For example, the slat angle assumed in the calculation of the introduceable external light amount Lb and the slat angle of the closed slat 35 are associated with each other, and the external light amount that is reduced from the external light amount Lb that can be introduced is calculated as the light shielding amount.

  In step S34, the light emission control of the slat LED 53 is performed to ensure the brightness in the bedroom 12. Here, the light shielding amount by the slat 35 is compared with the external light quantity Lb that can be introduced, and the slat LED 53 is caused to emit light based on the magnitude of the light shielding quantity with respect to the external light quantity Lb that can be introduced. For example, a light-blocking determination value serving as a reference for the light-blocking determination is set, and the slat LED 53 is caused to emit light if the ratio of the light-blocking amount to the introductible light quantity Lb is larger than the light-blocking determination value. Thereby, the shortage of the light amount when the light is blocked by the slat 35 is compensated by the light emission of the slat LED 53.

  Further, when the ratio of the light shielding amount to the installable outside light amount Lb is equal to or less than the light shielding determination value, the slat LED 53 is not caused to emit light. If the ratio of the slat light shielding amount with respect to the external light quantity Lb that can be introduced is increased by rotating the slat 35 to the closing side, the slat LED 53 may be caused to emit light while the slat 35 is rotated to the closing side.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  In the configuration in which the slat LED 53 is provided in the slat 35 of the shutter curtain 32, the angle of the slat 35 and the light emission of the slat LED 53 are controlled based on the actual light amount La and the introduceable external light amount Lb. In any of the controls, the indoor environment can be changed in accordance with the outdoor brightness and the state of introduction of external light into the bedroom 12. Further, in this configuration, when the slat LED 53 emits light, a situation similar to or similar to the case where external light is introduced through the shutter curtain 32 by the light emission of the slat LED 53 can be created. As a result, an atmosphere in which external light is taken into the bedroom 12 can be appropriately created.

  Since the awakening control is executed in the awakening control period set based on the wake-up time, outside light is actually taken into the bedroom 12 or outside light is taken in through the shutter curtain 32 according to the wake-up time. Such an atmosphere can be created by the light emission of the slat LED 53. Therefore, a comfortable awakening can be brought to the user.

  In the awakening control, since the slat LED 53 is caused to emit light when the actual outside light amount La is smaller than the first reference outside light amount Ref1, the slat LED 53 emits light even when the outdoors is still dark in preparation for awakening. it can. In addition, when the actual outside light amount La is equal to or greater than the first reference outside light amount Ref1, it is possible to urge a person to wake up by the outside light captured through the shutter curtain 32. That is, the light amount necessary for awakening can be secured in the bedroom 12 regardless of the outdoor brightness. Therefore, for example, the interior of the bedroom 12 can be brightened in the same manner when getting up, even when the amount of external light is less when it is raining than when it is sunny, or when the sunrise is late in winter compared to the summer.

  Since external light is captured and the slat LED 53 emits light during the period before the wake-up control, the wake-up is gradually promoted from before the wake-up time. In this case, since the sleep state of the person gradually shifts to the awake state, a comfortable awakening can be brought about at the wake-up time.

  If the user does not wake up even if external light is captured or the slat LED 53 emits light in the latter period of the awakening control, the indoor lighting device 18 emits light, and thus the person sleeps past the wake-up time. Can be suppressed. In this case, since the brightness in the bedroom 12 is ensured by the light emitted from the indoor lighting device 18, awakening can be promoted regardless of the outdoor brightness.

  In the daytime shutter control period, when a person feels excessive glare due to external light taken into the bedroom 12, the slat 35 is controlled to close and the slat LED 53 emits light. It is possible to secure the brightness in the bedroom 12 while reducing the above.

  If the slat LED 53 is provided in the approximate center of the slat 35 in the short side view when viewed from the front, and a plurality of slat LEDs 53 are provided in the longitudinal direction when viewed from the front, the slat 35 is provided in a fully closed state. An atmosphere can be created in which external light is inserted into the bedroom 12 through the slats 35. In addition, since the light of the slat LED 53 has directivity, by rotating the slat 35, not only the amount of light taken into the bedroom 12 but also the irradiation position can be adjusted. For example, the light of the slat LED 53 can be irradiated around the bed 15 to enhance a person's awakening effect, or the light of the slat LED 53 can be irradiated around the dressing table to provide an environment suitable for makeup.

Can do.

  (5) In the shutter curtain 32, each slat 35 may be opened and closed individually. In this case, for example, the other slats 35 can be opened while the slats 35 at the center of the shutter curtain 32 are fully closed.

  (6) Although the shutter curtain 32 is configured to open and close when the slat 35 rotates, the shutter curtain 32 may be configured to open and close when the slat 35 slides. For example, one of the slats 35 adjacent in the vertical direction is configured to slide to a position where the other slat 35 overlaps the other slat 35.

  (7) In the window portion 22, the shutter device 31 may be provided on the outdoor side of the sash door 23. In this case, since the shutter curtain 32 overlaps the sash door 23 on the outdoor side, when the slat LED 53 emits light with the slat 35 fully closed, the light of the slat LED 53 is transmitted through the sash door 23 in the same manner as outside light. 12 is inserted. Therefore, the atmosphere when the slat LED 53 is caused to emit light can be brought close to the atmosphere in which external light is actually inserted into the bedroom 12. Further, the sash door 23 may not be provided in the window portion 22.

  (8) In the shutter curtain 32, the plurality of slats 35 may be connected in a state of being aligned in the horizontal direction. In short, it is only necessary that external light is inserted into the bedroom 12 from between the slats 35 when the slats 35 are in an open state.

  (9) The shutter device 31 may be provided with respect to a window portion formed on the roof or ceiling, or may be provided with respect to an entrance / exit formed on the outer wall 21. In short, the shutter device 31 only needs to be provided for an opening through which external light is inserted into the bedroom 12.

  (10) The external light sensor 66 may detect the illuminance of sunlight or the altitude of the sun. In this case, in the bedroom server 61, the current season and time are calculated based on the illuminance of sunlight and the altitude of the sun detected by the external light sensor 66, and the illuminance and light intensity of the sunlight are used as past storage data. The current weather can be calculated by comparing.
