Description

  The present invention relates to a lighting control device, and more particularly to a lighting control device including a human sensor.

  Conventionally, a pyroelectric sensor detects a change in the amount of incident light due to fluctuations in outside light or curtains, and detects the sound of people entering the room as a countermeasure against the problem that a lighting fixture malfunctions. In addition, there is a control device that turns on a lighting fixture on condition that a human sensor detects within a predetermined time after detection (see Patent Document 1).

  In addition, in a conventional lighting fixture equipped with a human sensor, the human sensor is mounted at the end of the appliance because it is affected by noise and electromagnetic waves when the human sensor is brought close to the power line in the center of the appliance. There is a lighting fixture that can be mounted at the center of a lighting fixture without being affected by noise by using a light source of LED or organic EL and a direct current power source (see Patent Document 2).

As illustrated in FIG. 2, the lighting control system 500 performs lighting control of a room (region) divided into a plurality of unit areas 1 to 9.
The nine unit areas correspond to groups 1 to 9 which are illumination unit groups. Each group includes at least a lighting fixture 30 that irradiates (illuminates) each unit area, and a human sensor 40 (detection sensor) that detects the presence of a person in each unit area. Each group may include an illuminance sensor 50, a wall switch 60, and the like in addition to the lighting fixture 30 and the human sensor 40.

  As shown in FIG. 1, the controller 10 communicates with the communication unit 20 by a wireless signal or a wired signal. The controller 10 includes group status information 310 in which the status of each group is set and group adjacency information 320 in a storage device.

The controller 10 performs control to turn off the lighting fixtures 30 of the group in which the state sensed by the human sensor 40 is absent.
In addition, the controller 10 sets a group in which the human sensor 40 is changed from the absence state to the control target group, and when the mode information of the control target group is the normal mode, the status of other groups (present / absence) Regardless of the state and the lighting / extinguishing state), the lighting fixture 30 of the control target group is controlled to be lit.
Further, when the mode information of the control target group is the suppression mode, the controller 10 determines whether there is a group in which the lighting fixture 30 is in a lighting state among the groups other than the control target group, and the lighting state When it is determined that there is a group, the lighting fixtures of the control target group are turned on. When the controller 10 determines that there is no group in the lighting state, the controller 10 determines whether there is a group in which the human sensor 40 is present among the groups other than the control target group, and the lighting in the presence state. When it is determined that there is a unit group, control is performed to turn on the luminaires 30 of the control target group and the luminaires 30 of the group that is in the extinguished state and in the existing state.
Details of the control of the controller 10 will be described later.

  The communication unit 20 communicates with the controller 10 by a wireless signal or a wired signal.

The storage device 920 stores a computer program executed by the processing device 911, digital data used for calculation, and the like. The storage device 920 is, for example, an internal storage device such as a volatile memory or a nonvolatile memory, or an external storage device such as a magnetic disk device or an optical disk device. The group state information 310 and the group adjacent information 320 described above are stored in the storage device 920.

5A is a diagram showing the configuration of group status information 310 according to the present embodiment, and FIG. 5B is a diagram showing the configuration of group adjacency information 320 according to the present embodiment.
An outline of illumination control by the controller 10 in the illumination control system 500 will be described with reference to FIGS. 2 and 5.

As described above, FIG. 2 is a diagram illustrating an illumination target area in which the illumination control system 500 performs illumination control, and is a layout drawing when the human sensor 40 and the luminaire 30 are installed.
As shown in FIG. 2, in the illumination control system 500 according to the present embodiment, a room (region) that is subject to illumination control is divided into nine unit areas. The nine unit areas are divided so as to form a 3 × 3 matrix. Therefore, the other groups are arrange | positioned so that the groups 1-9 may surround the circumference | surroundings of the group 5 centering on the group 5. FIG.
In each group, one human sensor 40 and four lighting fixtures 30 arranged so as to surround the human sensor 40 are arranged.

  Regarding the configuration of each group (the number and arrangement of the lighting fixtures 30 and the human sensors 40), how to divide the room, how to divide and divide the groups, and the arrangement of the groups, the shape, width, and illumination of the room to be controlled Changes can be made as appropriate depending on the scale of control.

  For example, although there are nine groups in the present embodiment, it can theoretically be expanded to 2 bytes (65535) by increasing the database of the controller 10.

  The controller 10 receives a signal indicating whether or not the human sensor 40 of each group has detected a person from the communication unit 20, and controls lighting / extinguishing of the lighting fixtures 30 of each group based on the received signal.

  Each group is set to either the normal mode or the suppression mode. The user can set / change whether each group is set to the normal mode or the suppression mode from the PC setting device 80 or the like.

For the group set to the normal mode, the controller 10 unconditionally turns on the lighting fixtures 30 of the group when the human sensor 40 detects a person.
In addition, for the group set to the suppression mode, the controller 10 determines whether the adjacent group is turned on / off, or the presence / absence state of the person, even if the human sensor 40 detects a person. Then, the lighting fixtures 30 of the group are controlled to be turned on / off.

That is, the group in the normal mode is a group that is lit by single detection regardless of the state of other groups.
In addition, the group in the suppression mode is a group that is lit if the adjacent group is lit or present when a person is detected. Here, “suppression” means that false detection due to popcorn noise or the like of the human sensor 40 can be suppressed.

  As shown to Fig.5 (a), the group status information 310 is the detection information which is the information whether the human sensor 40 detected the person with respect to each group, and whether the lighting fixture 30 is lit. Illumination information that is such information is set.

In the detection information, the presence state (hereinafter also referred to as presence) is set when the human sensor 40 detects a person, and the absence state (hereinafter absent) when the human sensor 40 does not detect a person. Also called).
The human sensor 40 detects the presence / absence of a person in the arranged unit area and notifies the controller 10 of the presence state signal or the absence state signal (detection information). When the controller 10 receives the presence status signal or the absence status signal (detection information) via the communication unit 20, the controller 10 sets the presence status or the absence status in the detection information column corresponding to the corresponding group in the group status information 310.
At this time, the presence sensor 40 or the absence signal that the human sensor 40 outputs does not necessarily match the presence / absence of the person. For example, the human sensor 40 may maintain the presence state for a predetermined period without outputting the absence state signal even if the absence detection is actually detected immediately after the presence detection and the presence state signal are output. This control will be described later with reference to FIG.

In the lighting information, a lighting state (hereinafter also referred to as lighting) is set when the lighting fixture 30 is turned on, and a lighting state (hereinafter also referred to as turning off) is set when the lighting fixture 30 is turned off. Is set.
The controller 10 updates the illumination information column of the group state information 310 when the lighting control of the lighting fixture 30 is performed. For example, when the controller 10 controls lighting of a certain group of lighting fixtures 30, the controller 10 sets lighting in the lighting information column corresponding to the corresponding group in the group state information 310. In addition, when the controller 10 controls the lighting fixtures 30 of a certain group to be turned off, the controller 10 sets the lighting information column corresponding to the corresponding group in the group state information 310 to be turned off.

  As shown in FIG. 5B, in the group adjacency information 320, information indicating whether the mode is the normal mode or the suppression mode (mode information), the redetection time, and the adjacent group are set for each group.

  Adjacent groups are set for each group. For example, as shown in FIG. 5B, for groups 1, adjacent groups 2, 4, and 5 are set as adjacent groups. For group 5, neighboring groups 1, 2, 3, 4, 6, 7, 8, and 9 are set as adjacent groups.

As described above, the group (adjacent group) to be adjacent (set to the suppression mode) may be only the group that actually contacts next to each other, or the adjacent group even when it is not completely in contact with each other due to room layout or group arrangement. It may be set to.
The redetection time will be described later.

For example, the controller 10 performs illumination control as follows.
It is assumed that the user sets the group 1 in the room to the normal mode and the remaining groups 2 to 9 to the suppression mode from the wireless remote controller 70 or the PC setting device 80.
The group 1 set to the normal mode is lit unconditionally if the human sensor 40 detects a person regardless of the states of the adjacent groups 2 to 9.
However, even if the human sensor 40 detects a person, the groups 2 to 9 set in the suppression mode are not lit unless the adjacent groups are in a lighting state.

  For example, when group 5 (inhibition mode) detects human presence, the lighting states of a total of eight groups 1 to 4 and 6 to 9 are checked, and when all are turned off, group 5 is not turned on. If any one of the other groups is lit, the group 5 is lit.

However, even when the adjacent groups (groups 1, 2, 3, 4, 6, 7, 8, 9) of group 5 are all turned off, for example, group 2 in the adjacent group has detected a person. In the case of the failure, the group 2 and the group 5 are turned on simultaneously.
That is, in the case where the group 2 has been in the off state because all the adjacent groups (groups 1, 3, 4, 5, and 6) were in the off state and absent, although a person was detected in the past. is there. In this case, when the group 5 that has registered the group 2 as an adjacent group is detected, it is determined that a person has intruded for the first time, and the group 2 is also turned on.

According to the control of the controller 10 as described above, only one group in the normal mode is turned on when all the adjacent groups are turned off.
On the other hand, as described above, if the adjacent group is lit, the group in the suppression mode is turned on together with the adjacent group. Start lighting with the state group. Therefore, only one group in the suppression mode does not start lighting. However, the group in the suppression mode may have a situation in which, after starting lighting, the surrounding groups are turned off due to the absence, and only one group (self) is turned on in the present state.

  Whether each group is set to the normal mode or the suppression mode can be easily set or changed by the PC setting device 80 or the wireless remote controller 70. Further, the setting of adjacent groups for each group can be easily set and changed by the PC setting device 80 or the wireless remote controller 70.

  For example, if the user wants to turn on by single detection as in the normal mode, the setter (user) can select in advance a place where there is a safety problem if the lamp is not lit alone, such as a doorway of a room. In addition, the normal mode group is not limited to one, and a plurality of groups can be selected. Therefore, if all groups are set as normal groups, all groups are lit by single detection, and normal operation can be realized.

FIG. 6 is a diagram illustrating a timing chart of the holding time when the absence of the human sensor 40 is detected in the illumination control system 500 according to the present embodiment.
The human sensor 40 stores the holding time in a storage device in advance. The holding time can be arbitrarily set by the user.

As shown in FIG. 6, when the human sensor 40 actually detects a person (hereinafter referred to as presence detection) in a state where the holding time is not counted, the presence sensor 40 enters a presence state (1).
When the presence sensor 40 is actually detected for the first time after entering the presence state (hereinafter referred to as absence detection), the human sensor 40 starts counting the holding time while maintaining the presence state (2). That is, the human sensor 40 counts the holding time during a period in which the human sensor 40 is actually present but no human is present.
The human sensor 40 resets the holding time when it is detected during the holding time count (3).
When the presence sensor 40 detects the absence after resetting the holding time, the human sensor 40 enters the absence state. Then, the human sensor 40 starts counting the holding time from the time when it is absent (4).
The human sensor 40 is in an absence state for the first time when the holding time obtained by counting the holding time stored in advance has elapsed (5).

  As described above, once the presence sensor 40 detects the presence, the presence sensor 40 maintains the presence state unless the state where the person is actually absent continues for the holding time. For this reason, under the control of the controller 10, the lighting fixture 30 performs the extinguishing operation for the first time in the absence state after the lapse of the holding time.

If the adjacent group of the control target group is in the holding time, the controller 10 determines that the human sensor 40 of the adjacent group is present and is present based on the group state information 310, and detects the presence of the adjacent group. Control to light up.
The holding time is held and controlled by the human sensor 40 itself. However, for management, the current holding time data is also held by the controller 10 at the same time.

  At this time, the controller 10 reduces the lighting fixture 30 at an arbitrary dimming rate without causing the lighting device 30 to be faded dimming that gradually becomes darker or to maintain a dimming state for an arbitrary time until the lighting device 30 is turned off. It is possible to control the remaining state that maintains the light state.

  As described above, by controlling the presence / absence state of the human sensor 40, it is possible to prevent the lighting fixture 30 from being repeatedly turned on / off more than necessary in the case where a person enters and exits heavily. it can.

FIG. 7 is a flowchart showing the illumination control operation of the group in the normal mode in the controller 10 according to the present embodiment.
In FIG. 7, it is assumed that the arrangement of the groups is the arrangement described in FIG. 2, and that the group 1 is set to the normal mode.

In S101, group 1 (normal mode) is absent.
In S <b> 102, the controller 10 determines whether presence detection has occurred in the group 1. If the controller 10 determines that the presence detection has not occurred in the group 1, the process returns to S102.

If the controller 10 determines that presence detection has occurred in group 1 (occurrence occurs in S102), the controller 10 proceeds to S103 and sets group 1 as a control target group (control target lighting unit group).
In S103, the controller 10 turns on the lighting fixtures 30 of the group 1 and sets the detection information of the group 1 of the group state information 310 to the current state.

  In S <b> 104, the controller 10 refers to the group adjacent information 320 and determines whether an adjacent group is set for the group 1. When the adjacent group is not set (no setting at S104), the controller 10 advances the process to S107 and sets the group 1 in the absence waiting state.

As shown in FIG. 5B, it is assumed that groups 2, 4 and 5 are set as adjacent groups in group 1. In this case, the controller 10 advances the process to S105.
In S <b> 105, the controller 10 refers to the group status information 310, and in the adjacent groups (groups 2, 4, 5) of the group 1, the detection information is present and the illumination information is in the extinguished state. The processing device detects whether or not there is any.
Here, a group in which the detection information is in the present state and the illumination information is in the off state is referred to as a temporary group.

  In S105, when it is determined that there is no temporary group in the adjacent group of Group 1 (No in S105), the controller 10 advances the process to S107 and puts Group 1 in the absence waiting state.

As shown in FIG. 5A, it is assumed that the group 2 in which the detection information is present and the illumination information is in the extinguished state is a temporary group.
In this case, the controller 10 determines in S105 that there is a temporary group (group 2) among the adjacent groups of group 1 (in S105), and proceeds to S106.

  In S106, the controller 10 turns on the lighting fixtures 30 of the group 2, which is a temporary group. Thereafter, the controller 10 advances the process to S107 to place the group 1 in the absence waiting state.

  As described above, the controller 10 according to the present embodiment turns on the lighting fixtures 30 of the group 1 unconditionally when the presence detection is detected in the human sensor 40 of the group 1 set to the normal mode. . When groups 2, 4, and 5 are set as adjacent groups in group 1 in the normal mode, the adjacent group in group 1 in the normal mode is in the suppression mode, and is turned off for detection of the presence of a single person In the case (that is, in the case of a temporary group), the adjacent group in which the presence is detected is also turned on by the presence detection of the group 1 in the normal mode.

FIG. 8 is a flowchart illustrating the illumination control operation of the suppression mode group in the controller 10 according to the present embodiment.
In FIG. 8, it is assumed that the arrangement of the groups is the arrangement described in FIG. 2, and that the group 5 is set to the suppression mode.

In S201, group 5 (suppression mode) is absent.
In S <b> 202, the controller 10 determines whether presence detection has occurred in the group 5. If the controller 10 determines that the presence detection has not occurred in the group 5, the process returns to S202.

  When the controller 10 determines that the presence detection has occurred in the group 5 (occurrence occurs in S202), the controller 10 proceeds to S203 and sets the group 5 as a control target group (control target group).

  In S <b> 203, the controller 10 refers to the group adjacent information 320 and determines whether an adjacent group is set for the group 5. When the adjacent group is not set (no setting in S203), the controller 10 advances the process to S207.

  In S <b> 207, the controller 10 sets the detection information of the group 5 in the group status information 310 to the current status. In S207, since the group 5 is in the off state, the detection information is in the existing state and the illumination information is in the temporary group in the off state. Thereafter, the controller 10 advances the process to S211 to place the group 5 in the absence waiting state.

  As shown in FIG. 5B, it is assumed that groups 1, 2, 3, 4, 6, 7, 8, and 9 are set as adjacent groups in group 5. In this case, the controller 10 determines that an adjacent group has been set for the group 5 (set in S203), and advances the process to S204.

In S <b> 204, the controller 10 refers to the group state information 310, and in the adjacent groups of the group 5 (groups 1, 2, 3, 4, 6, 7, 8, 9), the lighting information is in the lighting state. It is determined whether or not there is. If it is determined that there is lighting information in the lighting state (in S204), the controller 10 advances the process to S206.
In S206, the controller 10 lights up the lighting fixtures 30 of group 5, and advances the processing to S208.

  In S <b> 208, the controller 10 refers to the group status information 310, and determines whether or not there is a temporary group among the adjacent groups (groups 1, 2, 3, 4, 6, 7, 8, 9) of the group 5. Determine. If it is determined that there is a temporary group, the controller 10 turns on the lighting fixtures 30 of the group determined to be a temporary group, and the process proceeds to S211. If it is determined that there is no temporary group, the controller 10 advances the process to S211.

If it is determined in S204 that there is no illumination information in the lighting state (none in S204), the controller 10 advances the process to S205.
In S <b> 205, the controller 10 refers to the group state information 310, and determines whether or not there is a temporary group among the adjacent groups (groups 1, 2, 3, 4, 6, 7, 8, 9) of the group 5. Determine.

  When it is determined in S205 that there is no temporary group, the controller 10 sets the group 5 of the group state information 310 to the temporary state (that is, the detection information is in the current state and the illumination information is in the off state) (S209). . Thereafter, the controller 10 advances the process to S211.

If it is determined in S205 that there is a temporary group, the controller 10 advances the process to S210.
In S210, the controller 10 lights together the lighting fixtures 30 of group 5 and the lighting fixtures 30 of the group determined to be in the temporary state in S205 (group 2 in FIG. 7). Thereafter, the controller 10 advances the process to S211.

As described above, the controller 10 according to the present embodiment, when the presence detection is detected in the human sensor 40 of the group 5 set to the suppression mode, the groups 1 to 4 set as the adjacent groups, If any one of the groups 6 to 9 is lit, group 5 is lit.
Further, even when all adjacent groups of the group 5 are in the off state, for example, if the group 2 is in the presence detection state, the group 5 is turned on and the group 2 is also turned on.
Further, when all adjacent groups are turned off and absent, or when no adjacent group is set, the group 5 is not turned on and is temporarily set. If the group 5 is in the temporary state, then when any of the groups 1 to 4 and 6 to 9 having the group 5 as the adjacent group is detected, the group 5 is the adjacent group in the temporary state of the group. Is detected as a lighting condition, and the group 5 is also lit.

The lighting control system according to the present embodiment includes a plurality of lighting fixtures, a controller that transmits a command signal for performing lighting control and function setting of the lighting fixtures, and a lighting fixture that is connected by a signal line and transmitted from the controller. And a plurality of communication units that receive the command signal and output it to the luminaire via the signal line. In addition, the lighting control system is connected to the communication unit by a signal line, and controls the wall switch that transmits operation information to the controller and detects the illuminance value in the corresponding range to control the blinking of the associated lighting fixture. An illuminance sensor that transmits illuminance information and a human sensor that detects that a person has entered the detection area and transmits detection information of the controller are provided.
When the human sensor detects a person, the lighting control system determines whether to turn on the lighting fixture according to the normal mode in which the lighting fixture assigned to the group is turned on unconditionally and the lighting / extinguishing state of the adjacent group. A suppression mode is provided. In the suppression mode, when the adjacent group is lit, the detected human sensor group is lit, and when the adjacent group is unlit, noise other than the intrusion of the person is the cause. Therefore, it is determined that the human sensor has malfunctioned and is not lit. However, when the human sensor in the suppression mode detects a person, the lighting control system determines that there is a person intrusion if there is a group that is in the presence detection state even if all adjacent groups are off. The adjacent group that has been in the off state and in the presence detection state is also lit at the same time.

  Here, it is possible that there is a setting that no registration of an adjacent group is performed for a group in the normal mode. In this case, nothing is set in the corresponding adjacent group column of the group adjacent information 320. In such a group, lighting control is performed based on the judgment of the group alone. If you do not register the adjacent group in the suppression mode, it will not be lit when the group itself is detected, but if it is temporarily present and there is another group that has registered that group in the adjacent group, A group of states can be lit.

  As for the output waveform when the pyroelectric sensor detects, the waveform when the noise other than the human body is detected is relatively shorter than the waveform when the motion of the human body is detected. By this, you can distinguish the human body from the rest. However, in this case, the operation time from when the human body is detected to when the lighting apparatus is turned on becomes long. According to the illumination control system according to the present embodiment, it is possible to distinguish between the human body and the others by controlling the controller using a simple human sensor that detects even a short waveform.

According to the illumination control system (illumination control device) according to the present embodiment, since the false detection of the human sensor is avoided by the control of the controller, it is possible to take measures with software without adding high-cost parts. It becomes.
Further, according to the illumination control system (illumination control device) according to the present embodiment, it is possible to take countermeasures by software, so that the degree of freedom of design of the luminaire can be achieved without restricting the installation location of the human sensor. Can be improved.

Embodiment 2. FIG.
The second embodiment will be described with reference to FIG.
FIG. 9 is a flowchart showing the illumination control operation (lighting control operation after re-detection) of the controller 10 according to the present embodiment.
In addition, the same code | symbol is attached | subjected to the structure which is common in Embodiment 1, and description may be abbreviate | omitted.

First, the outline of the illumination control operation (lighting control operation after re-detection) of the controller 10 according to the present embodiment will be described.
In the present embodiment, for example, it is assumed that the group set to the suppression mode is lit alone. For example, when a group in suppression mode is lit alone, for example, in the state where a plurality of adjacent suppression mode groups are lit, only one of them continues to be detected and continues to light. It is assumed that the group goes out when the group is absent.
As described in the first embodiment, each group is detected once, regardless of whether it is in the normal mode or the suppression mode. As long as this continues, it will continue to be lit alone.

  In a situation where a group in the suppression mode (hereinafter referred to as a corresponding group) is lit alone, a worker who is directly below the motion sensor 40 is in a stationary state for a holding time or longer, for example. The sense sensor 40 detects the absence, and the controller 10 turns off the lighting fixtures 30 of the corresponding group. Thereafter, even if the worker operates and the presence sensor 40 detects the presence of the adjacent group, the adjacent group is absent and turned off, so that the corresponding group cannot be turned on.

In order to avoid such a situation, the controller 10 singly turns off the group in the suppression mode that is lit alone, and then detects the presence again within a certain time (re-detection time). Even if it controls, it lights up. Such control is called re-detection lighting control.
As shown in FIG. 5B, in the group adjacency information 320, a redetection time is set for each group.
The re-detection time can be set for each group, and can be easily set and changed by the user using the PC setting device 80 or the wireless remote controller 70.

  Next, the redetection lighting control operation of the controller 10 according to the present embodiment will be described with reference to FIG.

In S301, the group 5 is assumed to be present and lit alone. That is, it is assumed that all the groups other than group 5 are absent and extinguished.
In S302, the presence sensor 40 of the group 5 detects the absence, but the counting of the holding time is started because it is within the holding time. Here, for example, in the unit area of group 5, it is assumed that the worker has stopped operating and the presence sensor 40 has detected the absence.

  In S303, the human sensor 40 of the group 5 becomes absent after the holding time has elapsed, and the controller 10 turns off the lighting fixtures 30 of the group 5. Here, for example, in the unit area of group 5, it is assumed that the luminaire 30 is turned off despite the presence of an operator.

  In S304, the presence sensor 40 of the group 5 detects the presence, and the group 5 enters the presence state. Here, for example, it is assumed that the presence sensor 40 detects the presence of the operator in the unit area of the group 5 when the worker starts the operation.

In step S304a, the controller 10 refers to the group state information 310 and determines whether all the groups other than the group 5 are absent and are turned off.
In S304a, when controller 10 determines that all groups other than group 5 are absent and extinguished (YES in S304a), the process proceeds to S305.

  In S304a, if controller 10 determines that there is a group other than group 5 that is absent and not extinguished (NO in S304a), controller 10 advances the process to S203 in FIG.

In S305, the controller 10 refers to the group adjacent information 320 and extracts the redetection time of the group 5. Then, it is determined whether or not the re-detection time has elapsed since the time when the group 5 entered the present state in S304.
If it is determined in S305 that the re-detection time has elapsed (after elapse of S305), the controller 10 advances the process to S306.
In S306, the controller 10 sets the group 5 of the group status information 310 as a temporary group, advances the processing to S308, and sets the group 5 to the absence waiting state.

If it is determined in S305 that the re-detection time has not elapsed (before the elapse of time in S305), the controller 10 advances the process to S307.
In S307, the controller 10 turns on the lighting fixtures 30 of the group 5, sets the group 5 of the group state information 310 to the lighting state, advances the process to S308, and sets the group 5 to the absence waiting state.
This is the end of the description of the redetection lighting operation in FIG.

  FIG. 10 is a flowchart showing an operation in which the re-detection lighting operation and the adjacent group detection operation are combined in the controller 10 according to the present embodiment.

As shown in FIG. 10, when the presence detection of the group 5 occurs (occurrence occurs in S402), the controller 10 determines whether a certain time (redetection time) has elapsed since the group 5 was turned off last time. (S403). If not, the controller 10 turns on the group 5 (S405). S402 to S405 are the same processes as S304 to S306 in FIG.
Thereafter, if there is a temporary group that has not been turned on because it was previously detected alone in the adjacent group of group 5, the controller 10 turns on the group simultaneously with group 5 (S406). Thereafter, the controller 10 advances the process to S414 to place the group 5 in the absence waiting state.

  If the presence detection of the group 5 is after the redetection time has elapsed (after the elapse of time in S403), the controller 10 determines whether or not the adjacent group of the group 5 is set (S404). When there is no adjacent group setting (no setting in S404), the controller 10 sets the group 5 to a temporary state (S410).

When there is an adjacent group setting (set in S404), the controller 10 sets the group 5 to a temporary state (S410).
The process proceeds to S407.

Since S407 to S409 and S411 to S413 are the same as the processes of S204 to S206 and S208 to S210 in FIG. 8, they will be briefly described below.
If there is a lighting group in the adjacent group of group 5 (in S407), group 5 is turned on (S409), and if there is a temporary group in the adjacent group, temporary The group in the state is also turned on at the same time (S411).
If all the adjacent groups in group 5 are turned off (not in S407), it is further determined whether or not there is a temporary state in the adjacent group (S408). The absence of the group in S408) makes the group 5 a temporary state (S412). For example, when group 2 is in a temporary state (group 2 is in a temporary state in S408), group 2 and group 5 are turned on simultaneously (S413).

  As described above, according to the control combining the re-detection lighting operation and the adjacent group detection operation shown in FIG. 10, for example, even when all adjacent groups are turned off and absent, for example, group 1 is turned on previously. On the other hand, when the time elapsed since the turn-off after the absence detection is shorter than the re-detection time set for the group 1, the group 1 is turned on. When a time longer than the re-detection time has elapsed, the temporary state is established without lighting, so that it is possible to prevent a malfunction that does not light when there is actually a person.

  According to the control of the controller 10 according to the present embodiment, the human sensor of the group that is turned on by detecting a person detects the absence of the person, and even after the light is turned off, the same group again within a certain time. When the human sensor detects a person, the corresponding group is lit alone, so that it is possible to prevent a malfunction that does not light up even though there is actually a person.
