Description

  The present invention relates to a security system and a lighting device used in the security system.

  In recent years, an increase in crime prevention awareness and communication infrastructure technology have led to an increasing number of cases of introducing crime prevention systems that are notified directly to security companies in emergency situations. However, the cost of introducing or maintaining this type of security system is by no means low, and there are still only a limited number of cases where it is introduced into private housing.

  In view of the situation as described above, there is an approach aiming at a crime prevention effect with a relatively simple and inexpensive facility such as installing a lighting device that detects and lights a nearby person on the exterior of a house. The following patent document 1 and patent document 2 are illustrated as a crime prevention system using this kind of illuminating device.

Patent Document 1 describes an illumination device in which a light source for normal illumination and a light source for threatening illumination are juxtaposed. In response to detection by a human sensor, the lighting device is driven to be lit with normal illumination in the normal mode and is lit with threatening illumination in the warning mode.
Thereby, the threatening effect to an intruder can be heightened.

  Patent Document 2 describes an illumination device (sensor light) that changes a lighting state of a light source according to a distance from a detection sensor to an intruder. This lighting device can enhance its threat effect by increasing the brightness of the light source as the distance to the intruder is closer.

  The conventional illumination device described in Patent Document 1 or Patent Document 2 described above is used alone, and a plurality of lighting devices do not operate in conjunction with each other. Therefore, the crime prevention effect covering the entire periphery of the house may not be sufficient.

  This invention is made | formed in view of said subject, and provides the illuminating device used for the crime prevention system which shows a high crime prevention effect in a housing exterior, and the said crime prevention system.

  According to the present invention, a plurality of lighting devices that are spaced apart from each other so as to surround at least a part of a crime prevention area, and a part or all of the plurality of lighting devices are associated with each other. And a sensor for detecting a person who enters or approaches the crime prevention area, and the first lighting device corresponding to the first sensor is triggered by detection by the first sensor. There is provided a crime prevention system that is lit in one mode and in which the second lighting device is lit in a second mode different from the first mode.

  According to the present invention, a lighting device that is installed apart from each other so as to surround at least a part of a crime prevention area, and can be used in combination with a plurality of sensors, and detects a nearby person and generates a detection signal And transmission means for transmitting and receiving the generated detection signal to and from the other lighting device, and light emitting means for lighting in a plurality of different modes, and the light emitting means Provided is a lighting device that is lit in a first mode triggered by the generated detection signal, receives the detection signal generated by the other lighting device, and is lit in a second mode different from the first mode. The

  According to the said invention, since the illuminating device (invasion location) corresponding to the detected sensor and the other illuminating devices are lit in different modes, the threat to the intruder and the intrusion are notified to the surroundings of the site. At the same time, the position (intrusion location) of the intruder can be notified. Therefore, the present invention has a higher crime prevention effect than the threatening effect of a single lighting device.

<Outline of the present invention>
The outline of the crime prevention system 100 in this embodiment or the illuminating device (garden lights L1-L4 and the gate lamp L5) used for the crime prevention system 100 is demonstrated using FIG.1, FIG.5 or FIG.7.
FIG. 1 is a diagram showing an external structure of a house A3 in which the crime prevention system 100 according to the present embodiment is introduced. FIG. 5 is a functional block diagram showing the functions of the garden lamp L1. FIG. 7 is a functional block diagram showing the functions of the garden lamp L2. Note that the type, number, arrangement, and the like of the house A3 and other components shown in FIG. 1 are examples, and may be implemented in different combinations.

The security system 100 includes a plurality of lighting devices (garden lights L1 to L4 and gate lights L5) that are spaced apart from each other so as to surround at least a part of the security area. The security system 100 is provided in association with some or all of the plurality of lighting devices, and is provided with a sensor (for example, a garden light L1) that detects a person who enters or approaches the security area. Sensor 14 etc.).
Here, the security area refers to a predetermined site (area) that is protected by the security system 100 of the present invention. In addition, here, a plurality of lighting devices (garden lights L1 to L4 and gate lights L5) are discretely arranged so as to surround at least a part of the crime prevention area. Or the state which surrounds a part. It should be noted that the detection range by the sensor and the security area do not necessarily match, and an area where intruders cannot be detected may be included in a part of the security area, or the detection range by the sensor is the security area. May extend to the outside area.
The crime prevention area in the present embodiment is a site where the house A3 is built, and includes a garage A1, an entrance porch A2, a garden A4, a warehouse A5 and the like in addition to the house A3. Further, in the crime prevention area in the present embodiment, the garden lamp L1, the garden lamp L2, the garden lamp L3, the garden lamp L4, and the gate lamp L5 are respectively arranged at illustrated positions, and these are used in the crime prevention system 100 of the present invention. Lighting device. The garden lights L1 to L4 are the same type of lighting device, and the gate lamp L5 is a lighting device installed at a position higher than the garden lights L1 to L4.

In the security system 100, the first lighting device (garden lamp L1) corresponding to the first sensor 14 is turned on in the first mode, triggered by the detection by the first sensor (for example, the sensor 14). Two illumination devices (for example, garden lamp L2) are lit in a second mode different from the first mode.
In the present embodiment, “lighting in the first mode” means that the garden lamp L1 (red LED 112) lights up while blinking. Further, “lighting in the second mode” means maintaining the state where the garden lamp L2 (red LED 212) is lit. The first aspect and the second aspect described here are exemplifications, and may be realized in different aspects in carrying out the present invention.

  Since it has the above features, the security system 100 has not detected the first lighting device (intrusion location) corresponding to the detected sensor, triggered by detection by some sensors. The second lighting device corresponding to the sensor can be lit in a different manner. As a result, the security system 100 can notify the intruder detection inside and outside the security area, and can also notify the intrusion location.

<About the structure and wiring of garden lights L1 to L4>
The configuration and wiring of the garden lights L1 to L4 used in the present embodiment will be described with reference to FIG. 2 or FIG. FIG. 2 is an outline view of the garden lamp L1 according to the present embodiment. FIG. 3 is a schematic diagram showing the base end side of the installed garden lamp L1.
In addition, since each component illustrated in each of the drawings already described may be described, refer to these drawings as appropriate.
The garden lights L2 to L4 have the same external shape as the garden lamp L1 shown in FIG.

The garden lamp L1 is mainly composed of a luminaire 11 and a support column 12. A white LED 111 and a red LED 112, which will be described later, are provided inside the illuminator 11, and emit light in white or red under a predetermined condition. The support column 12 includes a sensor 14 and a camera 16 (imaging device). The sensor 14 and the camera 16 are provided on a movable band 15 that is movable along the peripheral surface of the support column 12, and the user can adjust the directivity direction of the sensor 14 or the camera 16 by manually moving the movable band 15. it can.
That is, the garden lamp L1 (lighting device) supports the red LED 112 (light emitting means) that can be lit at least in the first mode or the second mode, the sensor 14 corresponding to the own device, and the red LED 112 and the sensor 14. And a support column 12 to be used. The sensor 14 or the camera 16 is movably provided along the peripheral surface of the support column 12.
As described above, since the sensor 14 or the camera 16 is movably provided along the peripheral surface of the support column 12, the position or orientation of the sensor 14 or the camera 16 is adjusted in accordance with the installation environment of the garden lamp L1. Can do. Therefore, an intruder can be detected with high accuracy, and the appearance of the intruder can be photographed.

The sensor 14 is a so-called human sensor, and can detect an approaching intruder using any one or a combination of infrared rays, ultrasonic waves, and visible light. In this embodiment, an example in which the sensor 14 is provided in the garden lamp L1 will be described. However, the sensor 14 may be arranged separately from the garden lamp L1.
The camera 16 is a device that captures a still image or a moving image (hereinafter, any of these images is referred to as an image), and captures the vicinity of the garden lamp L1 triggered by detection by any sensor. Start. In this embodiment, an example in which the camera 16 is provided in the garden lamp L1 will be described. However, the camera 16 may be disposed separately from the garden lamp L1. Moreover, the image image | photographed with the camera 16 may be memorize | stored in the memory | storage device (not shown) provided in the garden lamp L1, and may be memorize | stored in another memory | storage device.
Since the sensor 14 or the camera 16 is installed outdoors, it is preferable that the sensor 14 or the camera 16 is excellent in water resistance and dust resistance.

Further, a power supply hole 18 is provided on the base end side of the garden lamp L1 (the support column 12). The power supply hole 18 is an opening for introducing the power supply line 20 and the signal line 30 into the garden lamp L1, and the power supply line 20 and the signal line 30 are buried in the ground while protecting the surroundings with a protective tube 40. Then, it is wired to the garden lamp L1 (power supply hole 18) through the ground. Here, the base end side refers to the lower side when the garden lamp L1 is erected vertically with respect to the ground plane GL.
The power line 20 is connected to a switchboard (not shown), and the garden lamp L1 is supplied with power through the power line 20. Further, the signal line 30 of the garden lamp L1 is connected to the other garden lamps L2 to L4 or the gate lamp L5, and is concentrated in the junction box J1 installed on the outer wall of the house A3. The junction box J1 is a box for relaying the wiring inside and outside the house A3.
In FIG. 3, the power supply line 20 or the signal line 30 is illustrated as if each is a single line, but may not necessarily be a single line and may be composed of a plurality of lines.

  The form of the garden lamp L1 shown in FIGS. 2 and 3 is an example, and various forms can be adopted for the form and the installation position of the sensor 14 and the camera 16. The camera 16 is preferably installed at a position lower than the height of a general adult. In general, intruders often face their faces, and the angle from a lower position is easier to photograph the face.

The garden lights L2 to L4 are also provided with the same types of sensors and cameras as the garden lights L1.
The gate lamp L5 is provided with the same type of camera as the garden lamp L1, but is not provided with the same type of sensor. This is because the gate lamp L5 is installed in the vicinity of the entrance porch A2, as shown in FIG. 1, and the frequency of people approaching is higher than other places, and even if the sensor is installed together with the gate lamp L5, This is because the probability that a person who reacts to the sensor is a malicious intruder is low.

<About lighting control of garden lights L1-L4 or gate lamp L5>
The lighting control of the garden lights L1 to L4 or the gate lamp L5 will be described with reference to FIGS. 4 to 6 are functional block diagrams showing functions of the garden lamp L1. 7 to 9 are functional block diagrams illustrating functions of the garden lamp L2.

The garden lamp L1 or the garden lamp L2 is a lighting device that is installed apart from each other so as to surround at least a part of the crime prevention area and can be used in combination.
The garden light L1 (or the garden light L2) has a sensor 14 (sensor 24), a transmission unit 171 (transmission unit 271), and a red LED 112 (red LED 212).
The sensor 14 (sensor 24) detects a person in the vicinity and generates a detection signal.
The transmission unit 171 (transmission unit 271) transmits and receives the generated detection signal to and from other lighting devices.
The red LED 112 (red LED 212) lights up in a plurality of different modes. More specifically, the red LED 112 (red LED 212) is lit in the first mode triggered by the detection signal generated by itself, receives the detection signal generated by another lighting device, and is the first mode. Lights up in a different second mode.

  Here, in the description of “performing transmission / reception of a detection signal between other lighting devices”, the transmission / reception may be performed directly between the own device and the other lighting device, or other elements ( For example, it may be performed indirectly via the junction box J1 or the like. In the latter mode, when the detection signal is modified and transmitted when passing through other elements, the modified signal is also referred to as a “detection signal” in the present embodiment.

On the tip of the signal line 30 drawn into the house A3 via the junction box J1 is a lighting switch for switching the garden lights L1 to L4 or the gate lamp L5 on (lighting) / off (light extinction) (see FIG. A sensor switch (not shown) for switching on / off of sensors (including the sensor 14) included in the garden lights L1 to L4 is provided.
The garden lamps L1 to L4 or the gate lamp L5 are connected via a signal line 30 to a control signal generated by a resident operating a lighting switch or a sensor switch in the house A3 or a detection signal generated by each sensor. Can send and receive.

The lighting switch or sensor switch described above may be a switch that is manually operated to switch on / off, or may be a switch that automatically switches on / off according to a predetermined time or ambient light amount. Good.
In addition, it is preferable that switching of the lighting mode of the lighting device by the lighting switch (first switch) and switching of the detection function by the sensor switch (second switch) are performed independently. This is because the crime prevention system in the present embodiment can be used as a normal lighting system. More specifically, the sensor can be operated even when normal illumination is unnecessary, and each illumination device can be turned on as normal illumination even when intrusion detection is unnecessary.
Here, as described above, the sensor switch is a switch that switches activation and deactivation of a detection function by a sensor (for example, sensor 14 or the like).

Hereinafter, the lighting mode in each case will be described according to whether the lighting switch is on or off or whether or not each sensor detects (sensor switch on / off).
For example, when the garden lamp L1 (lighting device) is turned off and the lighting switch (first switch) is activated, the garden lamp L1 is lit in a normal manner (white LED 111) as shown in FIG. ). More specifically, the transmission unit 171 accepts that the lighting switch is turned on by a control signal transmitted from the signal line 30, and the dimming unit 172 causes the white LED 111 to emit light.
Here, the lighting switch is a switch that can switch the lighting mode of the lighting device as described above. Further, “lighting in the normal mode” refers to a state of lighting in a mode different from the first mode and the second mode, and in this embodiment, the white LED 111 is lit. Further, “the lighting switch is activated” means that the lighting switch is turned on.

  When the sensor 14 is activated (the sensor switch is turned on) and an intruder is detected by the sensor 14, the garden lamp L1 blinks the red LED 112 as shown in FIG. (First mode), the photographing by the camera 16 is started, and the detection signal is transmitted to other devices (garden lights L2 to L4 and the gate lamp L5). More specifically, when the sensor 14 detects an intruder in the above case, the transmission unit 171 transmits a detection signal generated by the sensor 14 to another device, and the dimming unit 172 causes the red LED 112 to blink, In step 173, shooting by the camera 16 is started.

Furthermore, when the garden lamp L1 (lighting device) is lit in the normal mode and detection by the sensor 14 is performed, the garden lamp L1 is changed from the normal mode to the first mode or the second mode as shown in FIG. Switch to the mode. That is, when detection by the sensor 14 is performed with the lighting switch turned on, the transmission unit 171 transmits the detection signal generated by the sensor 14 to another device, and the dimming unit 172 turns on the white LED 111. At the same time, the red LED 112 blinks, and the photographing unit 173 starts photographing by the camera 16.
Although not shown, when the lighting of the white LED 111 and the lighting (or blinking) of the red LED 112 are performed simultaneously, the illuminator 11 may be lit so that white and red are mixed. You may light up so that it may be divided into two. And the state in which lighting of the white LED 111 and blinking of the red LED 112 are performed in parallel is also referred to as a first aspect in the present embodiment. In addition, the state in which the lighting of the white LED 111 and the lighting of the red LED 112 are performed in parallel is also referred to as a second mode in the present embodiment.

  As described above, the garden lamp L1 (lighting device) is provided with the camera 16 (photographing device) that captures the surroundings of the garden lamp L1 corresponding to the sensor 14 triggered by detection by the sensor 14. Person can be photographed. Therefore, the crime prevention system 100 can enhance the crime prevention effect due to the presence of the camera 16.

Next, the case where the garden lamp L2 receives the detection signal transmitted from the garden lamp L1 in the case illustrated in FIG. 5 or FIG. 6 will be described.
As shown in FIG. 7, the detection signal transmitted in FIG. 5 is received by the transmission unit 271 included in the garden lamp L2, and the dimming unit 272 accordingly turns on the red LED 212 (second mode) and further shoots. The unit 273 starts shooting with the camera 26.
As shown in FIG. 8, the detection signal transmitted in FIG. 6 is received by the transmission unit 271 of the garden lamp L2, and the dimming unit 272 turns on the red LED 212 accordingly (second mode), and further shoots. The unit 273 starts shooting with the camera 26. Further, since the lighting switch is also turned on, the dimmer 272 turns on the white LED 211 as well as the red LED 212.

  As described above, since the crime prevention system 100 separates the normal lighting (normal mode) and the abnormal lighting (first mode / second mode), it can be used together with the normal lighting system. Further, even when each lighting device is lit in the normal mode, the lighting in the event of an abnormality is performed, so that the function of anomaly notification by intrusion detection is not hindered.

Next, in the case where the garden lamp L1 is controlled as shown in FIG. 7, the sensor 24 of the garden lamp L2 is activated (the sensor switch is turned on), and the sensor 24 intrudes. When a person is detected, as shown in FIG. 9, the garden lamp L2 blinks the red LED 212 (first mode).
More specifically, when the sensor 24 detects an intruder in the above case, the transmission unit 271 transmits the detection signal generated by the sensor 24 to another device, and the dimming unit 272 blinks the lit red LED 112. Let In the above case, the photographing unit 173 continuously performs photographing with the camera 16.

  That is, when the garden light L2 (second lighting device) is lit in the second mode, the second sensor 24 corresponding to the garden light L2 detects a person who enters or approaches the crime prevention area. When it does, lighting of the garden lamp L2 switches from a 2nd aspect to a 1st aspect. By this switching, it can be notified that the intruder has moved from the detection range of the garden lamp L1 (sensor 14) to the detection range of the garden lamp L2 (sensor 24), and the security system 100 tracks the intruder. Each lighting device (garden lights L1 to L4) can be operated.

In addition, as described above, triggered by detection by the first sensor 14, the camera 16 (photographing device) provided in the garden lamp L1 (first lighting device) starts continuous photographing, and the garden light L2 The camera 26 (photographing device) provided in the (second lighting device) also starts continuous photographing. Therefore, the crime prevention system 100 can capture the situation where the intruder moves without omission. Here, the continuous shooting includes continuous shooting of still images and shooting of moving images.
5 to 9, it is illustrated that the garden lamp L1 or the garden lamp L2 (at least a part of the plurality of lighting devices) includes a camera (photographing device). The lamp L4 or the gate lamp L5 is also provided with the same type of camera and operates in the same manner.

The above lighting switch is preferably operated as follows.
For example, when the amount of ambient light becomes small (sunset) or when a predetermined night time is reached, the lighting switch is automatically turned on, and as shown in FIG. 4, each lighting device (garden lights L1 to L4 and The white LED of the gate lamp L5) is turned on. Further, when the amount of ambient light increases (dawn) or reaches a predetermined morning time, the lighting switch is automatically turned off, and the white LED of each lighting device is extinguished.
At this time, since the on / off switching of the lighting switch is independent from the on / off switching of the sensor switch, each sensor mounted on the garden lamps L1 to L4 regardless of the daytime or nighttime. It is possible to maintain activation. Therefore, the security system 100 can turn on or blink each red LED according to detection of an intruder, and can start shooting with each camera, whether in the daytime or at night. It is.
In addition, when each illuminating device emits light in response to detection of an intruder in the security system 100, the light emission color is red as described above. Since red is a highly attractive color, it is more noticeable than other luminescent colors even during the daytime.

<Example of operation of security system 100>
Subsequently, an example of the operation of the crime prevention system 100 in the crime prevention area (outside of the house A3) in which the crime prevention system 100 constituted by the garden lights L1 to L4 and the gate lamp L5 that operate as described above is described.
FIG. 10 is a diagram illustrating a situation where an intruder H1 has entered from the vicinity of the garden lamp L1. FIG. 11 is a diagram illustrating a situation where the intruder H1 illustrated in FIG. 10 has moved to reach the vicinity of the garden lamp L3.
In FIG. 10 or FIG. 11, the moving path of the intruder H1 is indicated by a white arrow. In FIG. 10 or FIG. 11, the lighting device that is turned on in the first mode (red flashing) is indicated by the shaded area and the effect line in which the diagonal lines in two directions cross, and the lighting that is turned on in the second mode (red lighting). The device is shown in one-way hatched shading.

As shown in FIG. 10, the case where the intruder H1 invades from the vicinity of the garden lamp L1 is assumed. In this case, the sensor 14 corresponding to the garden lamp L1 detects the intruder H1, and the garden lamp L1 blinks red (first mode).
The detection signal generated by the sensor 14 is transmitted to each lighting device via the signal line 30, and the garden lights L2 to L4 and the gate lamp L5 are lit in red (second mode).
Furthermore, each camera (camera 16, camera 26, etc.) provided in the garden lights L1 to L4 and the gate lamp L5 starts photographing all at once triggered by detection by the sensor 14.

Next, as shown in FIG. 11, it is assumed that the intruder H1 moves clockwise around the house A3 and reaches the vicinity of the garden lamp L3. In this case, the intruder H1 is detected by the sensor 24 corresponding to the garden lamp L2 and the sensor (not shown) corresponding to the garden lamp L3.
The garden light L2 switches from red lighting to red flashing in response to detection by the sensor 24 corresponding to the own device. Further, the garden lamp L3 switches from red lighting to red flashing in response to detection by a sensor (not shown) corresponding to its own device.
In the transition of the situation as described above, each camera provided in the garden lights L1 to L4 and the gate lamp L5 continuously performs photographing.

  When the situation changes as described above, the garden lamp L1 first blinks red, and then the red lamp blinks in the order of the garden lamp L2 and the garden lamp L3. Therefore, when the lighting state of each lighting device is observed from the inside of the house A3 or around the crime prevention area, it can be determined that the intruder H1 has entered the crime prevention area and is moving clockwise.

As described above, the crime prevention system 100 can exhibit the following crime prevention effect by interlocking the light emitting means (red LED), sensor, or camera included in each lighting device.
(I) The effect of intimidating an intruder when the lighting device in the vicinity of the intrusion flashes red.
(Ii) The effect of informing the surroundings of detection of an intruder by illuminating the lighting device other than the intrusion location in red.
(Iii) The effect of facilitating the identification of the intrusion location by changing the lighting mode in the vicinity of the intrusion location and other locations.
(Iv) The effect of being able to capture the intruder with high accuracy by capturing the inside of the crime prevention area without omission by starting the imaging of each camera in conjunction with the detection of the intrusion.
With the effects as described above, the security system 100 can achieve a high security effect in the exterior of the house A3.

The present invention is not limited to the above-described embodiment, and includes various modifications and improvements as long as the object of the present invention is achieved.
For example, in the above-described embodiment, lighting (light emission) and photographing are combined to provide a crime prevention effect. However, sound may be combined therewith. That is, triggered by detection by one sensor, the lighting or simultaneous photographing according to the first aspect or the second aspect may be started, and an alarm sound or the like may be sounded.
In the above-described embodiment, the lighting device (garden lamp) includes a sensor that detects an intruder. However, the sensor may be provided at a location separated from each lighting device.

Moreover, although the above-described embodiment has been described on the assumption that the light emission amount during lighting or blinking is constant, the light emission amount may be changed according to the situation.
For example, the amount of light emitted from the lighting device corresponding to the sensor that currently detects the intruder H1 is increased, and the amount of light emitted from the lighting device corresponding to the sensor that detected the intruder H1 before the detection is decreased. May be. Thereby, the position where the intruder actually exists can be notified to the surroundings.
Or you may make the emitted light quantity of the gate lamp L5 which is most conspicuous more than the emitted light quantity of other illuminating devices (garden lights L1-L4). Thereby, the detection of an intruder can be shown more clearly around.

  In the above-described embodiment, it has been described that the directivity direction of the sensor or the camera can be changed by manually moving the movable band. However, the movable band may be moved automatically. For example, when the garden lamp L1 (transmission unit 171) receives a detection signal generated by the garden lamp L2 (sensor 24), the movable band 15 moves according to the detection signal and the sensor 14 or the camera 16 is directed. The direction may be directed to the direction of the garden lamp L2.

The above embodiment has been described on the assumption that an image capturing apparatus (camera) that captures an image is used. However, the present invention may be implemented without using the image capturing apparatus. That is, when the sensor detects a person who enters or approaches the crime prevention area, the crime prevention effect that can be achieved only by lighting of the lighting device may be realized.
In the above-described embodiment, the captured image is stored in the storage device. However, the image may be displayed on a monitor provided in a remote place (for example, in the house A3). Furthermore, an intruder may be specified by performing image processing on the image.

In the above-described embodiment, the crime prevention system has been described in which the red LED is turned on or blinking or is shot by the camera in response to detection of an intruder regardless of whether it is daytime or nighttime (turning on / off of the lighting switch). However, the present invention does not necessarily have to be implemented in this mode.
For example, since the light emission is less conspicuous during the day than at night, the present invention may be implemented in such a manner that the lighting or blinking of the red LED is restricted when the lighting switch is off, and only shooting by the camera is performed. .
Alternatively, during the daytime (when the lighting switch is turned off), the lighting of each lighting device may be performed in a light emission mode that is more conspicuous than at night (when the lighting switch is turned on). Here, the “conspicuous light emission mode” may be to change the hue of the light emission, to increase the light emission intensity by the same color light emission, or to increase the saturation by the light emission of the same color system, It is also possible to increase the blinking speed. Here, “the blinking speed is fast” means that it is fast enough to be recognized by a human.

  In the above-described embodiment, the signal lines 30 connected to the lighting switch (first switch) or the sensor switch (second switch) are collected by the junction box J1 and drawn into the house A3. A description has been given of a mode in which a plurality of lighting devices are controlled all at once according to / off.
