Description

    The present invention relates to a lighting system for a house.

  In houses, etc., a human detection sensor is provided, and lighting equipment is turned on / off based on the detection result of the human detection sensor. The lighting fixture can be turned off.

  When lighting a lighting fixture using a human detection sensor, there is a time lag between the time when a person enters the detection area of the human detection sensor and the time when the lighting fixture is turned on. Further, in the human detection sensor, it is difficult to detect a person when the person and the detection sensor are separated from each other or when there is an obstacle between the person and the detection sensor. For this reason, if it is going to light a lighting fixture by detecting the person who is moving with a human detection sensor, a lighting fixture may turn on after a person passes, or it may turn off during the passage of a person.

  Here, Patent Document 1 describes an interlocking luminaire in which a slave unit is disposed between two master units using a master unit and a slave unit, each of which is switched off, nightlight lighting, and normal lighting. ing. In this interlocking type lighting apparatus, when one parent device detects a person, it is normally turned on, and the child device and the other parent device are also normally turned on. Further, when one parent device no longer detects a person and the other parent device detects a person, the lighting is switched from normal lighting to nightlight lighting, and the child device and the other parent device are also switched to nightlight lighting.

  By the way, as a lighting space where a resident passes or enters in a house or the like, there are not only stairs but also a plurality of spaces adjacent to the corridor or the corridor, and the movement path of the resident when moving from one space to another space There is not always one, and the resident may go back in the middle of movement. In order to illuminate the illumination space in accordance with the movement of the resident, it is conceivable to change the combination of the luminaires that are interlocked. However, in the configuration of Patent Document 1, the combination of the luminaires that are interlocked is changed. In some cases, it is necessary to change the wiring to the lighting fixtures or the wiring between the lighting fixtures, and it is necessary to modify the wiring around the building.

  Another method for enabling the lighting fixtures to light in accordance with the movement of the resident is to provide lighting fixtures and human detection sensors in each of the lighting spaces, and wire each of the lighting fixtures and human detection sensors in advance. It is possible to keep it. However, in this case, lighting control of the lighting fixture is complicated.

  The present invention has been made in view of the above-described facts, and provides an illumination system capable of accurately illuminating a plurality of illumination spaces each provided with a luminaire according to the movement of a resident and simplifying the control. For the purpose.

  A first aspect for achieving the above object is provided in each of a plurality of lighting spaces including an entrance space and a sleeping space, each of which is adjacent to at least one of the other spaces and allows a resident to move.

The lighting space is shown in a list.

  As shown in FIG. 4, in the lighting system 40, for example, when the human detection sensor 56 </ b> F in the staircase hall 38 detects a resident, the lighting apparatus (downlight 50 </ b> B or The footlight 52B) is turned on. Further, in the lighting system 40, when the human detection sensor 56C in the hallway 26 detects a person, the WIC 24 that is the lighting space adjacent to the hallway 26 and the hallway 26, the lighting equipment of the washroom 28 and the toilet 36 (downlights 50A, 50B, 50C, 54 or footlights 52A, 52B, 52C and downlight 54) are turned on. Furthermore, when the person detection sensor 56A in the bedroom 12 detects a person, the lighting fixtures (the direct light 44 and the downlight 50A or the footlights 48 and 52A) of the bedroom 12 and the WIC 24 are turned on.

  The controller 42 stores a lighting pattern (lighting pattern in FIG. 4), and sets an illumination space for lighting the lighting fixture based on the detection result of the human detection sensor 56 and the lighting pattern. When the plurality of human detection sensors 56 detect a resident, the controller 42 sets an illumination space for lighting the lighting fixture based on each detection result, and turns on the lighting fixture in the set lighting space. At this time, if any of the sleep sensors 58A and 58B detects that a sleeping person is in the bedroom 12, the controller 42 turns on the footlights 48 and 52, and either of the sleep sensors 58A or 58B. If no sleeper is detected, the direct light 44 or the downlight 50 is turned on.

  Hereinafter, as an operation of the present embodiment, lighting of each lighting fixture in the lighting space will be described as an operation of the lighting system 40. The lighting system 40 controls the lighting of the lighting space in the lighting management area in the sleeping time zone from the time when the occupant sleeps in the bedroom 12 until he gets up. Note that a preset time can be applied as the time before going to bed in the bedtime, and the preset time or the wake-up time set by the alarm timer 60 can be applied as the wake-up time.

  FIG. 5 shows an outline of processing repeatedly executed by the controller 42 during the bedtime. In the first step 100, the controller 42 performs person detection and bedtime detection. That is, in step 100, each detection result of the human detection sensor 56 is read to detect whether or not there is a resident in any lighting space, and each detection state of the sleep sensor 58 is read to live in the bed 16. It is detected whether the person is in the floor. In step 100, the sleep state when the sleeping person is in bed 16 is detected from the detection state of the sleep sensor 58.

  Here, if any of the human detection sensors 56A to 56F detects a resident, or if the sleep sensors 58A and 58B detect that a sleeping person is in one of the beds 16A and 16B, An affirmative determination is made at step 102 and the routine proceeds to step 104. In this step 104, based on the detection result of the human detection sensor 56, the sleep state detected by the sleep sensor 58, and a preset lighting pattern, an illumination space for lighting the lighting fixture and a lighting fixture are set. . That is, a lighting fixture that is lit in the lighting management area is set. Thereafter, in step 106, control is performed so that the set lighting fixture is turned on.

  Thus, for example, when the person detection sensor 56A of the staircase hall 38 detects a person heading to the bedroom 12 without detecting a sleeping person in any of the beds 16A and 16B of the bedroom 12, the controller 42 causes the stairway hall 38 to It sets so that the lighting fixture of the corridor 26 adjacent to may be lighted, and the downlight 50B of the corridor 26 is lighted.

  When the occupant detected by the human detection sensor 56F moves to the hallway 26 and is detected by the human detection sensor 56C, the controller 42 turns on the lighting fixtures of the hallway 26, the WIC 24, the washroom 28, and the toilet 36. Set to light up. Thereby, the downlight 50B of the corridor 26, the downlight 50A of the WIC 24, the downlight 50C of the washroom 28, and the downlight 54 of the toilet 36 are turned on.

  Further, when the human detection sensor 56B of the WIC 24 detects a resident, the direct light 44 of the bedroom 12 is turned on together with the down light 50A of the WIC 24, the down light 50B of the corridor 26, and the down light 50C of the washroom 28.

  Therefore, not only when the resident moves from the staircase hall 38 to the bedroom 12 through the corridor 26 and the WIC 24, but also when the resident moves from the staircase hall 38 to the bedroom 12 through the corridor 26, the washroom 28, and the WIC 24, Each of the lighting spaces is illuminated prior to the occupant's movement. Further, since the resident can enter the bright bedroom 12, it is easy to enter the bed 16.

  When the direct light 44 (44A, 44B) of the bedroom 12 is turned on, the color temperature is a light bulb color (orange to yellow, 2700k (Kelvin) to 3000k), and the illuminance of the bedroom 12 is 500 lx (lux). The brightness (illuminance) is preferably below (for example, 100 lx). Thereby, when the previous sleeper enters the bedroom 12, the inside of the bedroom 12 is illuminated with appropriate brightness. In particular, when the interior of the bedroom 12 is dark with the WIC 24 illuminated, the eyes may not feel familiar and the interior of the bedroom 12 may appear to be dark, but the bedroom 12 may have an appropriate brightness. By being illuminated, the resident does not feel that the bedroom 12 is too dark or too bright. In addition, the resident who enters the room first can enter the bed 16 with appropriate brightness, and the bed 12 can be promoted to sleep by having the brightness and color temperature in the bedroom 12 prompting to sleep.

  In the lighting control for the previous sleeping person, when the sleeping sensor 58 detects that the sleeping person has entered the bed 16, the direct light 44 is dimmed (for example, the illuminance of the bedroom 12 is about 9 lx), It goes out when the person's sleep is detected. Thereby, the sleeping person can fall asleep quickly. Furthermore, when the footlight 48 of the bedroom 12 is turned on while the first sleeping person is sleeping on the bed 16, the footlight 48 on the side of the bed 16 opposite to the bed 16 on which the sleeping person is entering. May be lit. Thereby, it can suppress that the bed 16 side with a sleeping person becomes unnecessarily bright. Further, the footlight 48 of the bedroom 12 that is lit may be turned off when the sleeping sensor 58 detects that the sleeping person has fallen asleep, for example, according to the sleeping state of the sleeping person who has entered the bed.

  On the other hand, when there is a sleeping person in any of the beds 16 of the bedroom 12, the controller 42 sets the footlights 48 (48A, 48B) and 52 (52A to 52C) as lighting fixtures to be lit. Thereby, when the resident moves to the bedroom 12, the resident's feet can be illuminated, so that the resident can move to the bedroom 12 smoothly. Further, even if the resident opens the doors 20A and 20B to enter the bedroom 12, the light of the WIC 24 can be prevented from entering the bedroom 12, so that sleep of the sleeper who is entering the bed 16 is disturbed. Can be prevented.

  On the other hand, when the sleeping person wakes up in the middle of sleep (halfway awakening), the controller 42 lights up the sleeping person's footlight 48 (footlight 48A or footlight 48B) that has awakened halfway. Thereby, since it can suppress that the inside of the bedroom 12 becomes dark, the sleeper who awakened halfway can sleep again with peace of mind.

  Moreover, the sleeping person who awakened midway is detected by the human detection sensor 56B by opening the door 20A (or the door 20B) in order to go to the toilet 36. Thereby, the controller 42 lights the footlight 52B of the corridor 26 and the footlight 52C of the washroom 28 together with the footlight 52A of the WIC 24. Further, when a sleeping person who has awakened is detected by the human detection sensor 56 </ b> B in the hallway 26, the controller 42 turns on the downlight 54 of the toilet 36. Thereby, the sleeping person who has awakened can enter the toilet 36 smoothly.

  The controller 42 is preferably turned on with the output of the downlight 54 suppressed, and when the sleeper entering the toilet 36 is detected by the human detection sensor 56E, the output is gradually increased to make it brighter. Thereby, since the inside of the toilet 36 is gradually brightened, it is possible to prevent the sleeper who has entered the toilet 36 from becoming suddenly bright and dazzling his eyes. Further, when the sleeper leaves the toilet 36 and returns, the footlights 52A to 52C and the footlight 48 are turned on, so that the sleeper who comes out of the toilet 36 smoothly returns to the bedroom 12 and enters the bed 16. You can floor.

  Here, when the first sleeper wakes up at the wake-up time, the controller 42 turns on the footlight 48, but when the last (second) sleeper wakes up and leaves the bed, the human detection sensor 56A goes out of bed. A person (resident) is detected. As a result, the controller 42 turns on the direct light 44 of the bedroom 12 and turns on the downlight 50A of the WIC 24, so that the inside of the bedroom 12 and the WIC 24 become bright.

Incidentally, in the lighting system 40, whether or not each of the six human detection sensors 56 (56A to 56F) detects a resident, and each of the two sleep sensors 58 (58A and 58B) enter the floor. It is determined whether or not it is detected. For this reason, the combination of the detection result of the human detection sensor 56 and the determination result of the sleep sensor 58 is 2 ⁶ × 2 ² = 256, and the CPU of the controller 42 performs arithmetic processing corresponding to each combination of the determination results. It will be.

  Here, when the human detection sensors 56 (56B to 56E) other than the human detection sensors 56A and 56F detect the resident, the controller 42 omits the detection of the human detection sensor 56A provided in the staircase hall 38. ing. In addition, the controller 42 omits detection by the human detection sensor 56A provided in the bedroom 12 when at least one of the sleep sensors 58A and 58B detects a person entering the bed. That is, when any of the human detection sensors 56B to 56E detects a resident, the controller 42 ignores the detection of the human detection sensor 56F as unnecessary, and the sleep sensors 58A and 58B detect the sleeper. If it is, the detection of the human detection sensor 56A is ignored as unnecessary.

  Thereby, the combination of the detection results of the human detection sensors 56A to 56F and the detection results of the sleep sensors 58A and 58B is as shown in FIG. 6 and FIGS. 7 (A) to 7 (C). Note that FIG. 6 shows a case where neither of the sleep sensors 58A and 58B has detected a sleeping bed in bed (OFF). Further, FIG. 7A shows a sleeper 58A (shown by bed A) detected by the sleep sensor 58A of the bed 16A (ON), and the sleep sensor 58B (shown by bed B) of the bed 16B is turned on. This shows a case where a sleeping bed is not detected. Further, FIG. 7B shows a case where the sleep sensor 58A does not detect the sleeping person who has entered the bed and the sleep sensor 58B does not detect the sleeping person who has entered the bed, and FIG. C) shows a case where each of the sleep sensors 58A and 58B detects a sleeping person who is in bed. Moreover, in FIG. 6, FIG. 7 (A)-FIG.7 (C), the human detection sensor which has detected the resident in order from the top is increased and shown in order from one. Furthermore, the mark * in FIGS. 6 and 7A to 7C indicates that detection is omitted.

  As shown in FIGS. 6 and 7A to 7C, when the human detection sensors 56B to 56E detect the resident, the detection by the human detection sensor 56F is omitted, and the sleep sensor 58A, When at least one of 58B is detecting a sleeping person who is entering the floor, the detection result combination is 85 by omitting the detection by the human detection sensor 56A. As a result, the arithmetic processing required for the CPU provided in the controller 42 is reduced.

  Therefore, the controller 42 can suppress an increase in the processing load of the CPU when the human detection sensors 56A to 56F are provided. In addition, the detection results of the sleep sensors 58A and 58B are based on whether or not the sleeper's entry is detected, or whether or not at least one of the sleep sensors 58A and 58B detects the sleeper entering the bed. Therefore, if the sleep sensors 58A and 58B are regarded as one, an increase in the processing load of the CPU can be further suppressed. Thereby, the controller 42 can simplify control in the case of using the detection results of the human detection sensors 56A to 56B and the sleep sensors 58A and 58B.

  Moreover, in the illumination system 40, since a lighting fixture is lighted prior to the movement of the resident, it is possible to prevent the resident from moving in a dark space that is difficult to see in front. In the lighting system 40, since the lighting fixtures in the surrounding lighting space adjacent to the lighting space are also turned on together with the lighting space in which the resident is present, the destination is accurately brightened regardless of the direction the resident moves. it can.

  Furthermore, in the lighting system 40, when there is a sleeping person in the bedroom 12 and when the sleeping person awakens midway, the foot lighting devices (footlights 48 and 52) are turned on, so that the lighting device lights up the sleeping person's sleep. Can be prevented, and sleepers who have been awakened can be prevented from feeling dazzling and uncomfortable.

  Further, in the lighting system 40, each of the plurality of lighting fixtures and the plurality of human detection sensors 56 (56A to 56F) is connected to one controller 42, and the lighting of each of the plurality of lighting fixtures is performed by the controller 42. Control is performed based on the detection result of the human detection sensor 56. For this reason, for example, when changing the lighting pattern or the like, the program executed by the controller 42 or the lighting pattern stored in the controller 42 may be changed, so that work such as changing the signal wiring becomes unnecessary.

  In the present embodiment, the lighting fixture for the staircase hall 38 that is the entrance space is omitted. However, lighting control may be performed by providing a lighting fixture in the staircase hall 38 and including the lighting fixture for the staircase hall 38. In this case, the lighting device in the staircase hall 38 may be turned on when the human detection sensor 56F in the staircase hall 38 detects a resident and when the human detection sensor 56C in the hallway 26 detects a resident. Moreover, as a lighting fixture provided in the staircase hall 38, it is preferable that the lighting fixture which illuminates the staircase hall 38 and the step lighting fixture which illuminates the floor surface are provided.

  Further, in the present embodiment, the description has been given by taking as an example the house 10 in which the bedroom 12, WIC 24, the corridor 26, the washroom 28, and the toilet 36 as the sleeping space are arranged with the staircase hall 38 as the entrance space. The arrangement is not limited to this. Arbitrary arrangement | sequence provided with two or more between sleeping space and entrance space can be applied to lighting space.
