1. Embodiment 1.1 Embodiment 1
1.1.1 Configuration FIG. 1A shows the lighting control system of the first embodiment. The lighting control system of the present embodiment includes two lighting control devices 10 (first lighting control device 10A and second lighting control device 10B) and two interlocking lighting devices 20 (201, 202). Each of the two lighting control devices 10 is connected to the light source 30 and the sensor 40, and each of the two interlocking lighting devices 20 is connected to the light source 30. In the lighting control system of the present embodiment, the lighting control device 10 functions as a master device, and the interlocking lighting device 20 functions as a slave device controlled by the master device. The light source 30 includes one or more LEDs, as shown in FIGS. 1B and 1C. The sensor 40 is a motion sensor that outputs a detection signal when a person in a predetermined area (for example, an area around the corresponding lighting control device 10) is detected. Therefore, the lighting control system can be operated depending on the presence or absence of a person.

In addition, in the lighting control system of the present embodiment, the second lighting control device 10B is electrically connected to the power supply 50. The power supply 50 is an AC power supply that outputs an AC voltage having a predetermined effective value and frequency. For example, when the power source 50 is a commercial AC power source, the effective value is 100V (or 200V) and the frequency is 60Hz (or 50Hz). Further, a switch 60 is arranged between the second lighting control device 10B and the power supply 50.

As shown in FIG. 1C, the interlocking lighting device 20 includes a connection terminal portion 210, a drive circuit 220, and a feed terminal portion 230.

The connection terminal unit 210 is a terminal for receiving electric power from the lighting control device 10. The connection terminal portion 210 includes a pair of connection terminals (first and second connection terminals) 211 and 212. For example, the first connection terminal 211 is a terminal for the voltage line, and the second connection terminal 212 is a terminal for the neutral line.

The drive circuit 220 is electrically connected to the connection terminal portion 210. Further, the drive circuit 220 is electrically connected to the light source 30. The drive circuit 220 is configured to turn on the light source 30 when the electric power input to the connection terminal unit 210 satisfies a predetermined condition. The predetermined condition is that the electric power is equal to or higher than a value obtained by applying an AC voltage having a predetermined effective value and frequency for a predetermined time. Further, the drive circuit 220 is configured to turn off the light source 30 when the electric power input to the connection terminal portion 210 does not satisfy the predetermined condition. The drive circuit 220 causes the light source 30 to have a predetermined size based on, for example, the voltage between the pair of connection terminals 211 and 212 of the connection terminal section 210 (equal to the voltage between the pair of feed terminals 231 and 232 of the feed terminal section 230). The constant current is supplied to turn on the light source 30. Such a drive circuit 220 is realized by, for example, a switching power supply. Specifically, the drive circuit 220 includes a rectifier circuit that rectifies the voltage between the pair of connection terminals 211 and 212, a boost chopper circuit that boosts the output of the rectifier circuit, a step-down chopper circuit that steps down the output of the boost chopper circuit, and the like. Prepare Then, in the drive circuit 220, by adjusting the circuit constant, the operation starts when an AC voltage having a predetermined effective value and frequency is applied between the pair of connection terminals 211 and 212 for a predetermined time or longer, and the light source 30 Is configured to light up. When the voltage is no longer applied between the pair of connection terminals 211 and 212, the drive circuit 220 finishes its operation, whereby the light source 30 is turned off.

The feed terminal portion 230 is electrically connected to the connection terminal portion 210. The feed terminal portion 230 has the same role as the connection terminal portion 210. The feed terminal unit 230 includes a pair of feed terminals (first and second feed terminals) 231 and 232. For example, the first feed terminal 231 is a voltage line terminal, and is electrically connected to the first connection terminal 211. The second feed terminal 232 is a neutral wire terminal and is electrically connected to the second connection terminal 212.

As shown in FIG. 1B, the lighting control device 10 includes a power supply terminal unit 110, a lighting circuit 120, an interlocking terminal unit 130, a power supply circuit 140, a determination circuit 150, a control circuit 160, and a sending terminal unit 170. , And an input device 180. Further, the lighting control device 10 includes a housing 190, as shown in FIG. The power supply terminal unit 110, the lighting circuit 120, the interlocking terminal unit 130, the power feeding circuit 140, the determination circuit 150, the control circuit 160, the sending terminal unit 170, and the input device 180 are housed in the housing 190. It The lighting control device 10 is electrically connected to a lighting fixture 70 including a light source 30 and a sensor 40, as shown in FIG. 2. The lighting fixture 70 is, for example, a downlight installed in a state of being embedded in the ceiling.

The power supply terminal unit 110 is used to receive power from the power supply 50. The power supply terminal unit 110 includes a pair of power supply terminals (first and second power supply terminals) 111 and 112. For example, the first power supply terminal 111 is a voltage line terminal, and the second power supply terminal 112 is a neutral line terminal.

The lighting circuit 120 is electrically connected to the power supply terminal portion 110. Further, the lighting circuit 120 is electrically connected to the light source 30. The lighting circuit 120 is configured to light the light source 30 based on the electric power input to the power supply terminal unit 110. For example, the lighting circuit 120 supplies a constant current of a predetermined magnitude to the light source 30 based on the voltage between the pair of power supply terminals 111 and 112 to light the light source 30. Such a lighting circuit 120 is realized by, for example, a switching power supply. Specifically, the lighting circuit 120 includes a rectifier circuit that rectifies the voltage between the pair of power supply terminals 111 and 112, a boost chopper circuit that boosts the output of the rectifier circuit, and a step-down chopper circuit that steps down the output of the boost chopper circuit. Prepare

The interlocking terminal unit 130 is used to connect the lighting control device 10 to a device (another lighting control device 10 or the interlocking lighting device 20) that operates in conjunction with the lighting control device. The interlocking terminal unit 130 includes a pair of interlocking terminals (first and second interlocking terminals) 131 and 132. For example, the first interlocking terminal 131 is a terminal for a voltage line, and is connected to the first power supply terminal 111 via the power feeding circuit 140. The second interlocking terminal 132 is a neutral wire terminal and is electrically connected to the second power supply terminal 112.

The power feeding circuit 140 is a circuit for outputting electric power from the interlocking terminal unit 130 based on the electric power input to the power supply terminal unit 110. The power supply circuit 140 is, for example, a triac, and is electrically connected between the first power supply terminal 111 and the first interlocking terminal 131. Therefore, while the power supply circuit 140 is on (the triac is on), the first power supply terminal 111 and the second power supply terminal 112 of the power supply terminal unit 110 are the first interlocking terminal 131 and the second interlocking terminal 131 of the interlocking terminal unit 130. Each of them is electrically connected to 132. In this case, the voltage applied between the first and second power supply terminals 111 and 112 of the power supply terminal section 110 is applied between the first and second interlocking terminals 131 and 132 of the interlocking terminal section 130. That is, the power feeding circuit 140 causes the power input to the power supply terminal unit 110 to be output from the interlocking terminal unit 130. On the other hand, while the power feeding circuit 140 is off (the triac is off), the first interlocking terminal 131 is electrically separated from the first power supply terminal 111. Therefore, even if a voltage is applied between the first and second power supply terminals 111 and 112 of the power supply terminal section 110, this voltage is not applied between the first and second interlocking terminals 131 and 132 of the interlocking terminal section 130. ..

The determination circuit 150 is a circuit that makes a determination based on the power input to the interlocking terminal unit 130. When the power is input to the interlocking terminal unit 130, the determination circuit 150 is configured to determine whether or not the power input to the interlocking terminal unit 130 satisfies a predetermined condition. The predetermined condition is that the electric power is equal to or more than a value obtained by applying an AC voltage having a predetermined effective value and frequency for a predetermined time as described above. For example, the determination circuit 150 includes a capacitor that is charged by the voltage between the first and second interlocking terminals 131 and 132 of the interlocking terminal unit 130 and a comparison circuit that compares the voltage across the capacitor with a predetermined threshold value. Prepare The comparator circuit outputs a high level output signal when the voltage across the capacitor is equal to or higher than a predetermined threshold value, and outputs a low level output signal when the voltage across the capacitor is less than the predetermined threshold value. .. Note that the determination circuit 150 does not determine whether the power input to the interlocking terminal unit 130 satisfies a predetermined condition when the power is not input to the interlocking terminal unit 130.

The feed terminal unit 170 is electrically connected to the power supply terminal unit 110. The feed terminal portion 170 has the same role as the power supply terminal portion 110. The feed terminal unit 170 includes a pair of feed terminals (first and second feed terminals) 171 and 172. For example, the first feed terminal 171 is a terminal for a voltage line, and is electrically connected to the first power supply terminal 111. The second feed terminal 172 is a terminal for a neutral wire and is electrically connected to the second power supply terminal 112.

The input device 180 is a device for receiving an instruction from a user. The user is, for example, a builder, a manager, or another person of the lighting control system. The input device 180 outputs either the first instruction signal or the second instruction signal to the control circuit 160 according to a user's operation. The input device 180 is, for example, a DIP switch or a selector.

The control circuit 160 is configured to control the lighting circuit 120 and the power feeding circuit 140. The control circuit 160 is configured to operate with the power of the power supply 50 input to the power supply terminal unit 110. That is, the control circuit 160 starts the operation when the power from the power supply 50 is input to the power supply terminal section 110, and ends the operation when the power from the power supply 50 is not input to the power supply terminal section 110.

The control circuit 160 has a lighting function and an interlocking function. The lighting function is a function for lighting the light source 30 connected to the lighting control device 10 and operating a device electrically connected to the interlocking terminal unit 130 of the lighting control device 10 in conjunction with the lighting control device 10. is there. In the lighting function, the control circuit 160 controls the lighting circuit 120 to light the light source 30 in response to the occurrence of the first event, and controls the power supply circuit 140 to satisfy a predetermined condition from the interlocking terminal unit 130. A lighting process for outputting electric power is performed. The first event is that the sensor 40 has detected a predetermined state. The predetermined state is that a person exists in the predetermined area. In other words, the first event is that the control circuit 160 has received a detection signal from the sensor 40. In the lighting process, the control circuit 160 turns on the power supply circuit 140 for a predetermined lighting time P2 (see FIG. 3) so that the power output from the interlocking terminal unit 130 satisfies a predetermined condition. The lighting time P2 is set to a predetermined time or longer. In other words, the lighting function continues the lighting process for the predetermined lighting time P2. In the lighting function, the control circuit 160 lights the light source 30 for the lighting time P2. The interlocking function is a function for interlocking with another lighting control device 10 electrically connected to the interlocking terminal unit 130 of the lighting control device 10. In the interlocking function, the control circuit 160 controls the lighting circuit 120 to light the light source 30 when the determination circuit 150 determines that the power input to the interlocking terminal unit 130 satisfies a predetermined condition. In the interlocking function, the control circuit 160 lights the light source 30 for the lighting time P2.

Further, the control circuit 160 has a first function and a second function.

The first function is a function of controlling the power supply circuit 140 in response to the occurrence of the second event and performing a notification process of outputting electric power that does not satisfy the predetermined condition from the interlocking terminal unit 130. The second event is that the control circuit 160 starts to operate due to the power input to the power supply terminal unit 110. Therefore, the control circuit 160 can be caused to perform the notification process by the first function by a simple process of inputting power to the power supply terminal unit 110 and starting the operation of the control circuit 160. In the notification process, the control circuit 160 turns on the power supply circuit 140 for a time P1 (see FIG. 3) shorter than the predetermined time so that the power output from the interlocking terminal unit 130 does not satisfy the predetermined condition. For example, the control circuit 160 performs the process of turning on the power supply circuit 140 only for the time P1 multiple times (twice in the present embodiment) at predetermined intervals. The predetermined interval is set such that the power output from the interlocking terminal unit 130 does not satisfy the predetermined condition even if the power supply circuit 140 is turned on for a plurality of times P1. As described above, the drive circuit 220 of the interlocking lighting device 20 lights the light source 30 when the electric power input to the connection terminal portion 210 satisfies a predetermined condition. Therefore, it is possible to reduce the possibility that the interlocking lighting device 20 will light the light source 30 during the notification processing by the first function.

The second function includes an invalidation process for invalidating the interlocking function when the determination circuit 150 determines that the power input to the interlocking terminal unit 130 does not satisfy the predetermined condition. Further, the control circuit 160 is configured to enable the second function for a specified time after starting the operation and disable the second function after the specified time has elapsed. Therefore, since the second function is enabled only during the time when the control circuit 160 of the first lighting control device 10A may perform the notification process, the second function unintentionally disables the interlocking function due to noise or the like. It is possible to reduce the possibility of the accident Here, the specified time is set to be equal to or longer than the time required for the control circuit 160 to complete the notification process, for example. With this configuration, it is possible to reduce the possibility that the control circuit 160 of the second lighting control device 10B invalidates the second function before the control circuit 160 of the first lighting processing device 10A performs the notification process.

Further, the control circuit 160 has a first mode in which the first function is enabled and the second function is disabled, and a second mode in which the first function is disabled and the second function is enabled. The control circuit 160 is configured to operate in one of the first mode and the second mode according to the instruction received by the input device 180. More specifically, the control circuit 160 is configured to operate in the first mode when receiving the first instruction signal from the input device 180 and to operate in the second mode when receiving the second instruction signal from the input device 180. To be done. Therefore, the setting of the interlocking operation between the lighting control devices 10 can be changed by switching between the first mode and the second mode.

Such a control circuit 160 is realized by, for example, a microcomputer including a memory and a processor. That is, the above-described functions (lighting function, interlocking function, first function, second function, etc.) are realized by the processor of the microcomputer executing the program stored in the memory. The control circuit 160 enables the lighting function, the interlocking function, the first function, and the second function when starting the operation.

In the lighting control system of the present embodiment, the first lighting control device 10A and the light source 30 and the sensor 40 connected to the first lighting control device 10A are installed outdoors. The second lighting control device 10B and the light source 30 and the sensor 40 connected to the second lighting control device 10B are installed indoors. Further, the interlocking lighting devices 201 and 202 and the light sources 30 connected to the interlocking lighting devices 201 and 202 are also installed indoors.

The control circuit 160 of the first lighting control device 10A is set to the first mode, and the control circuit 160 of the second lighting control device 10B is set to the second mode. Further, as shown in FIG. 1A, the first and second power supply terminals 111 and 112 of the first lighting control device 10A are connected to the first and second feed terminals 171 and 172 of the second lighting control device 10B by power supply lines, respectively. It is electrically connected. The first and second power supply terminals 111 and 112 of the second lighting control device 10B are electrically connected to the power supply 50 via the switch 60 by a power supply line. The first and second connection terminals 211 and 212 of the interlocking lighting device 201 are electrically connected to the first and second interlocking terminals 131 and 132 of the first lighting control device 10A by power lines. The first and second feed terminals 231 and 232 of the linked lighting device 201 are electrically connected to the first and second feed terminals 231 and 232 of the linked lighting device 202 by power lines. The first and second connection terminals 211 and 212 of the interlocking lighting device 202 are electrically connected to the first and second interlocking terminals 131 and 132 of the second lighting control device 10B by power lines. Thus, the interlocking terminal unit 130 of the first lighting control device 10A is electrically connected to the interlocking terminal unit 130 of the second lighting control device 10B via the interlocking lighting device 201 and the interlocking lighting device 202.

1.1.2 Operation The operation of the lighting control system of the present embodiment will be briefly described below with reference to FIG.

At time t11, when the switch 60 is turned on from off, the voltage of the power supply 50 is applied between the power supply terminals 111 and 112 of the second lighting control device 10B. Further, the voltage of the power supply 50 is applied between the power supply terminals 111 and 112 of the first lighting control device 10A via the sending terminal portion 170 of the second lighting control device 10B. As a result, the control circuits 160 of the first and second lighting control devices 10A and 10B start operating. Since the control circuit 160 of the first lighting control device 10A is in the first mode, the first function performs the process of turning on the power supply circuit 140 only for the time P1 twice at predetermined intervals. The interlocking terminal unit 130 of the first lighting control device 10A is electrically connected to the interlocking terminal unit 130 of the second lighting control device 10B via the interlocking lighting device 201 and the interlocking lighting device 202. Therefore, the interlocking terminal unit 130 of the second lighting control device 10B receives the power output from the interlocking terminal unit 130 of the first lighting control device 10A. Here, in the first function, the power supply circuit 140 is controlled so that the power output from the interlocking terminal unit 130 does not satisfy the predetermined condition. Therefore, the determination circuit 150 of the second lighting control device 10B determines that the power input to the interlocking terminal unit 130 does not satisfy the predetermined condition, and the control circuit 160 of the second lighting control device 10B performs the interlocking function. To disable. Further, in the interlocking lighting devices 201 and 202, the electric power input to the connection terminal portion 210 does not satisfy the predetermined condition, so the drive circuit 220 does not turn on the light source 30.

At time t12, when the detection signal is output from the sensor 40 of the first lighting control device 10A, the control circuit 160 of the first lighting control device 10A executes the lighting function and lights the light source 30. In addition, the control circuit 160 of the first lighting control device 10A turns on the power supply circuit 140 for the lighting time P2 longer than the predetermined time so that the power output from the interlocking terminal unit 130 satisfies the predetermined condition. Accordingly, the interlocking terminal unit 130 of the second lighting control device 10B receives the power output from the interlocking terminal unit 130 of the first lighting control device 10A. Since the interlocking function is disabled in the second lighting control device 10B, even if the power output from the interlocking terminal unit 130 of the first lighting control device 10A satisfies a predetermined condition, the second lighting control device 10B The control circuit 160 does not execute the interlocking function and does not turn on the light source 30. On the other hand, in the interlocking lighting devices 201 and 202, the drive circuit 220 lights the light source 30 at the time when the electric power input to the connection terminal unit 210 satisfies a predetermined condition (time t13). At time t14 when the lighting time P2 has elapsed from time t12, the control circuit 160 of the first lighting control device 10A turns off the light source 30 and further turns off the power supply circuit 140. As a result, in the interlocking lighting devices 201 and 202, electric power is not supplied to the connection terminal portion 210, so that the drive circuit 220 ends its operation and the light source 30 is turned off.

At time t15, when the detection signal is output from the sensor 40 of the second lighting control device 10B, the control circuit 160 of the second lighting control device 10B executes the lighting function and lights the light source 30. Further, the control circuit 160 of the second lighting control device 10B turns on the power supply circuit 140 for the lighting time P2 that is equal to or longer than the predetermined time so that the power output from the interlocking terminal unit 130 satisfies the predetermined condition. As a result, the interlocking terminal unit 130 of the first lighting control device 10A receives the power output from the interlocking terminal unit 130 of the second lighting control device 10B. Here, in the first lighting control device 10A, since the interlocking function is effective, the control circuit 160 turns on the light source 30 at the time when the power input to the interlocking terminal unit 130 satisfies the predetermined condition (time t16). Let Similarly, in the interlocking lighting devices 201 and 202, the drive circuit 220 lights the light source 30 when the electric power input to the connection terminal unit 210 satisfies a predetermined condition (time t16). At time t17 when the lighting time P2 has elapsed from time t15, the control circuit 160 of the second lighting control device 10B turns off the light source 30 and further turns off the power supply circuit 140. As a result, in the interlocking lighting devices 201 and 202, electric power is not supplied to the connection terminal portion 210, so that the drive circuit 220 ends its operation and the light source 30 is turned off. Further, at time t18 when the lighting time P2 has elapsed from time t16, the control circuit 160 of the first lighting control device 10A turns off the light source 30.

Particularly, in the present embodiment, the first lighting control device 10A is installed outdoors and the second lighting control device 10B is installed indoors. Then, the indoor second lighting control device 10B does not interlock with the outdoor first lighting control device 10A. Therefore, when an outdoor person is detected by the sensor 40 connected to the first lighting control device 10A, it is possible to suppress the indoor second lighting control device 10B from lighting the light source 30 connected thereto. .. Therefore, unnecessary lighting of the light source 30 by the lighting control device 10 can be suppressed.

1.1.3 Summary In the lighting control system of the present embodiment, the first and second lighting control devices 10A and 10B are electrically connected to each other by the interlocking terminal portions 130. The control circuit 160 of the first lighting control device 10A controls the power supply circuit 140 of the first lighting control device 10A in response to the occurrence of the second event to cause the interlocking terminal unit 130 of the first lighting control device 10A to perform a predetermined condition. It has the 1st function which performs the notification processing which outputs the electric power which does not satisfy. The control circuit 160 of the second lighting control device 10B disables the interlocking function when the determination circuit 150 determines that the power input to the interlocking terminal unit 130 of the second lighting control device 10B does not satisfy the predetermined condition. It has two functions. If the second event has not occurred, when the light source 30 connected to the first lighting control device 10A is turned on by the lighting function, the second lighting control device 10B is interlocked with the first lighting control device 10A by the interlocking function. Then, the light source 30 connected to the second lighting control device 10B is turned on. Similarly, when the light source 30 connected to the second lighting control device 10B is turned on by the lighting function, the first lighting control device 10A operates in conjunction with the second lighting control device 10B by the interlocking function to cause the first lighting control device 10A to operate. The connected light source 30 is turned on. On the other hand, when the second event occurs, the interlocking function is disabled in the second lighting control device 10B. Therefore, even if the light source 30 connected to the first lighting control device 10A is lit by the lighting function, the second lighting control device 10B does not operate in conjunction with the first lighting control device 10A, and the second lighting control device 10B operates. The connected light source 30 is not turned on. On the contrary, when the light source 30 connected to the second lighting control device 10B is turned on by the lighting function, the first lighting control device 10A operates in conjunction with the second lighting control device 10B by the interlocking function to perform the first lighting control. The light source 30 connected to the device 10A is turned on. Here, in the first function, the first lighting control device 10A outputs electric power that does not satisfy the predetermined condition from the interlocking terminal unit 130. In the second function, the second lighting control device 10B invalidates the interlocking function when the power input to the interlocking terminal unit 130 does not satisfy the predetermined condition. Therefore, according to the lighting control system of the present embodiment, the setting of the interlocking operation between the lighting control devices 10A and 10B can be changed without changing the wiring between the lighting control devices 10A and 10B. Secondly, it is possible to change the setting of the interlocking operation between the lighting control devices 10A and 10B using the existing configuration (interlocking terminal unit 130).

In other words, the lighting control system of the present embodiment executes the following lighting control method. In the lighting control method, the control circuit 160 of the first lighting control device 10A controls the power feeding circuit 140 of the first lighting control device 10A, and the predetermined condition is not satisfied from the interlocking terminal unit 130 of the first lighting control device 10A. Including outputting power. In the lighting control method, the determination circuit 150 of the second lighting control device 10B determines whether or not the electric power input to the interlocking terminal unit 130 of the second lighting control device 10B satisfies a predetermined condition. including. Further, in the lighting control method, when the power input to the interlocking terminal unit 130 of the second lighting control device 10B does not satisfy the predetermined condition, the interlocking function is disabled by the control circuit 160 of the second lighting control device 10B. Including that. Also according to the lighting control method, the setting of the interlocking operation between the lighting control devices 10A and 10B can be changed without changing the wiring between the lighting control devices 10A and 10B. Secondly, it is possible to change the setting of the interlocking operation between the lighting control devices 10A and 10B by using the existing configuration (interlocking terminal unit 130).

In addition, in the lighting control device 10 of the present embodiment, the control circuit 160 has the first mode in which the first function is enabled and the second function is disabled, and the second mode in which the first function is disabled and the second function is enabled. And modes. The first function is a function of controlling the power supply circuit 140 in response to the occurrence of the second event and performing a notification process of outputting electric power that does not satisfy the predetermined condition from the interlocking terminal unit 130. The second function is a function of performing an invalidation process for invalidating the interlocking function when the determination circuit 150 determines that the power input to the interlocking terminal unit 130 does not satisfy the predetermined condition. The control circuit 160 is configured to operate in one of the first mode and the second mode according to the instruction received by the input device 180. Therefore, when it is not desired to interlock the one lighting control device 10 with the other lighting control device 10, the control circuit 160 of the one lighting control device 10 is set to the first mode, and the other lighting control device 10 is controlled. The circuit 160 may be set to the second mode. Therefore, according to the lighting control device 10, the setting of the interlocking operation between the lighting control devices 10 can be changed without changing the wiring between the lighting control devices 10. Secondly, it is possible to change the setting of the interlocking operation between the lighting control devices 10 by using the existing configuration (interlocking terminal unit 130). Furthermore, by switching between the first mode and the second mode, the setting of interlocking between the lighting control devices 10 can be changed. Further, even if the second event occurs in both the lighting control devices 10, only the control circuit 160 set in the first mode performs the notification process. Therefore, it is not necessary to individually generate the second event in the plurality of lighting control devices 10.

1.2 Embodiment 2
1.2.1 Configuration FIG. 4A shows the lighting control system of the second embodiment. The lighting control system of the present embodiment includes two lighting control devices 11 (first lighting control device 11A and second lighting control device 11B) and two interlocking lighting devices 20 (201, 202). Each of the two lighting control devices 11 is connected to the light source 30 and the sensor 40, and each of the two interlocking lighting devices 20 is connected to the light source 30. In the lighting control system of the present embodiment, the lighting control device 11 functions as a master device, and the interlocking lighting device 20 functions as a slave device controlled by the master device.

As shown in FIG. 4B, the lighting control device 11 includes a power supply terminal unit 110, a lighting circuit 120, an interlocking terminal unit 130, a power supply circuit 140, a determination circuit 150, a control circuit 161, and a sending terminal unit 170. , Is provided. Further, the lighting control device 11 is similar to the lighting control device 10 of the first embodiment in that the power supply terminal unit 110, the lighting circuit 120, the interlocking terminal unit 130, the power supply circuit 140, the determination circuit 150, and the control circuit 161. A housing 190 (see FIG. 2) for housing the feed terminal unit 170 and the feed terminal unit 170 is provided. The lighting control device 11 is electrically connected to the lighting fixture 70 (see FIG. 2) including the light source 30 and the sensor 40, similarly to the lighting control device 10 of the first embodiment.

The power supply terminal unit 110, the lighting circuit 120, the interlocking terminal unit 130, the power feeding circuit 140, the determination circuit 150, and the sending terminal unit 170 of the lighting control device 11 are the same as those in the first embodiment.

The control circuit 161 is configured to control the lighting circuit 120 and the power feeding circuit 140. The control circuit 161 is configured to operate with the power of the power supply 50 input to the power supply terminal unit 110. The control circuit 161 starts operation when electric power from the power supply 50 is input to the power supply terminal section 110, and ends operation when electric power from the power supply 50 is not input to the power supply terminal section 110. Here, the control circuit 161 does not end the operation immediately when the power from the power supply 50 is not input to the power supply terminal unit 110, and does not end when the power from the power supply 50 is input to the power supply terminal unit 110. The grace period is configured so that the operation can be continued. For example, such a configuration can be realized by storing a certain amount of electric power from the power source 50 using a capacitive element such as a capacitor.

The control circuit 161 has the same lighting function and interlocking function as the control circuit 160.

Further, the control circuit 161 has a first function and a second function. The first function of the control circuit 161 includes a notification process, a continuous lighting process, and an end process. The notification process is a process of controlling the power supply circuit 140 in response to the occurrence of the second event and outputting the power that does not satisfy the predetermined condition from the interlocking terminal unit 130. The second event is that the electric power input to the power supply terminal unit 110 has changed in a predetermined pattern. The predetermined pattern is that the electric power input to the power supply terminal unit 110 becomes 0 only during the period within the predetermined time range. The upper limit of the time range is set shorter than the grace period of the control circuit 161. Further, in the present embodiment, the electric power input to the power supply terminal unit 110 is the AC power from the power supply 50. Therefore, the lower limit of the time range is set to be longer than the period in which the AC voltage applied between the first and second power supply terminals 111 and 112 of the power supply terminal unit 110 by the power supply 50 becomes zero. That is, by temporarily stopping the supply of electric power from the power supply 50 to the lighting control device 11 within the time range, it is possible to cause the control circuit 161 to execute the notification process by the first function. Further, in the notification process, like the control circuit 160, the control circuit 161 supplies power for a time P1 (see FIG. 5) shorter than the predetermined time so that the power output from the interlocking terminal unit 130 does not satisfy the predetermined condition. Turn on circuit 140. In the continuous lighting process, after the notification process, until the third event occurs, the lighting circuit 120 is controlled to continue lighting the light source 30, and the power supply circuit 140 is controlled to control a predetermined amount from the interlocking terminal unit 130. This is a process of continuously outputting electric power that satisfies the conditions. In the present embodiment, the third event is the same as the second event. That is, the power input to the power supply terminal unit 110 has changed in a predetermined pattern. As a matter of course, in the first function, the notification process is not performed during the continuous lighting process. The second function includes an invalidation process for invalidating the interlocking function when the determination circuit 150 determines that the power input to the interlocking terminal unit 130 does not satisfy the predetermined condition. Further, the second function enables the interlocking function when the power input to the interlocking terminal unit 130 from the state satisfying the predetermined condition to the state not satisfying the predetermined condition after the disabling process. Including conversion processing. That is, the activation process is a process of activating the interlocking function when the power input to the interlocking terminal unit 130 does not satisfy the predetermined condition after the inactivation process.

Such a control circuit 161 is realized by, for example, a microcomputer including a memory and a processor. That is, the above-described functions (lighting function, interlocking function, first function, second function, etc.) are realized by the processor of the microcomputer executing the program stored in the memory. The control circuit 161 enables the lighting function, the interlocking function, the first function, and the second function when starting the operation.

In the lighting control system of the present embodiment, the first lighting control device 11A and the light source 30 and the sensor 40 connected to the first lighting control device 11A are installed outdoors. The second lighting control device 11B and the light source 30 and the sensor 40 connected to the second lighting control device 11B are installed indoors. Further, the interlocking lighting devices 201 and 202 and the light sources 30 connected to the interlocking lighting devices 201 and 202 are also installed indoors.

As shown in FIG. 4A, the first and second power supply terminals 111 and 112 of the first lighting control device 11A are electrically connected to the power supply 50 via a switch (first switch) 61 by a power supply line. The first and second power supply terminals 111 and 112 of the second lighting control device 11B are electrically connected to the power supply 50 via a switch (second switch) 62 by a power supply line. The first and second connection terminals 211 and 212 of the interlocking lighting device 201 are electrically connected to the first and second interlocking terminals 131 and 132 of the first lighting control device 11A by power lines, respectively. The first and second feed terminals 231 and 232 of the linked lighting device 201 are electrically connected to the first and second feed terminals 231 and 232 of the linked lighting device 202 by power lines. The first and second connection terminals 211 and 212 of the interlocking lighting device 202 are electrically connected to the first and second interlocking terminals 131 and 132 of the second lighting control device 11B by power lines. In this way, the interlocking terminal unit 130 of the first lighting control device 11A and the interlocking terminal unit 130 of the second lighting control device 11B are electrically connected to the power supply 50 via the switches 61 and 62, respectively.

1.2.2 Operation The operation of the lighting control system of the present embodiment will be briefly described below with reference to FIG. In the initial state (before time t21), the switches 61 and 62 are both on, and the control circuit 161 of the first and second lighting control devices 11A is operating.

When the switch 61 is turned off for the period within the time range (time t21), the electric power input to the power supply terminal unit 110 of the first lighting control device 11A becomes 0 for the period within the predetermined time range. Therefore, the control circuit 161 of the first lighting control device 11A determines that the second event has occurred, and performs the process of turning on the power supply circuit 140 for the time P1 at a predetermined interval by the notification process of the first function. Two times. The interlocking terminal unit 130 of the first lighting control device 11A is electrically connected to the interlocking terminal unit 130 of the second lighting control device 11B via the interlocking lighting device 201 and the interlocking lighting device 202. Therefore, the interlocking terminal unit 130 of the second lighting control device 11B receives the power output from the interlocking terminal unit 130 of the first lighting control device 11A. Here, in the first function, the power supply circuit 140 is controlled so that the power output from the interlocking terminal unit 130 does not satisfy the predetermined condition. Therefore, the determination circuit 150 of the second lighting control device 11B determines that the power input to the interlocking terminal unit 130 does not satisfy the predetermined condition, and the control circuit 161 of the second lighting control device 11B performs the interlocking function. To disable. Further, in the interlocking lighting devices 201 and 202, the electric power input to the connection terminal portion 210 does not satisfy the predetermined condition, so the drive circuit 220 does not turn on the light source 30.

After the notification process, the control circuit 161 of the first lighting control device 11A starts the continuous lighting process (time t22). In the continuous lighting process, the control circuit 161 of the first lighting control device 11A controls the lighting circuit 120 to light the light source 30 and controls the power supply circuit 140 to control the interlocking terminal until the third event occurs. The output of the electric power satisfying the predetermined condition from the unit 130 is continued. As a result, in the interlocking lighting devices 201 and 202, the drive circuit 220 lights the light source 30 at the time when the electric power input to the connection terminal unit 210 satisfies a predetermined condition (time t23).

At time t24 thereafter, when the detection signal is output from the sensor 40 of the second lighting control device 11B, the control circuit 161 of the second lighting control device 11B executes the lighting function and lights the light source 30. Further, the control circuit 161 of the second lighting control device 11B turns on the power supply circuit 140 for the lighting time P2 that is equal to or longer than the predetermined time so that the power output from the interlocking terminal unit 130 satisfies the predetermined condition. However, since the first lighting control device 11A and the interlocking lighting devices 201 and 202 have already turned on the light source 30, these operations do not change. At time t25 when the lighting time P2 has elapsed from time t24, the control circuit 161 of the second lighting control device 11B turns off the light source 30 and further turns off the power supply circuit 140. Even in this case, since the first lighting control device 11A is performing the continuous lighting process, the power supply to the connection terminal portion 210 of the interlocking lighting devices 201 and 202 is not lost.

After that, when the switch 61 is turned off for the period within the time range (time t26), the power input to the power supply terminal unit 110 of the first lighting control device 11A becomes 0 for the period within the predetermined time range. .. Since the control circuit 161 of the first lighting control device 11A is in the continuous lighting process, it determines that the third event has occurred, controls the lighting circuit 120 to turn off the light source 30, and controls the power supply circuit 140. Then, the output of the electric power satisfying the predetermined condition from the interlocking terminal unit 130 is stopped. As a result, the power supply circuit 140 of the first lighting control device 11A is turned off. As a result, in the interlocking lighting devices 201 and 202, electric power is not supplied to the connection terminal portion 210, so that the drive circuit 220 ends its operation and the light source 30 is turned off. In addition, since the electric power input to the interlocking terminal unit 130 of the second lighting control device 11B changes from a state in which the predetermined condition is satisfied to a state in which the predetermined condition is not satisfied, the second function activation processing causes The control circuit 161 of the two-lighting control device 11B enables the interlocking function.

At time t27, when the detection signal is output from the sensor 40 of the first lighting control device 11A, the control circuit 161 of the first lighting control device 11A executes the lighting function and lights the light source 30. In addition, the control circuit 161 of the first lighting control device 11A turns on the power supply circuit 140 for the lighting time P2 longer than the predetermined time so that the power output from the interlocking terminal unit 130 satisfies the predetermined condition. Accordingly, the interlocking terminal unit 130 of the second lighting control device 11B receives the power output from the interlocking terminal unit 130 of the first lighting control device 11A. Here, since the interlocking function is enabled in the second lighting control device 11B, the control circuit 161 causes the light source 30 to operate when the power input to the interlocking terminal unit 130 satisfies the predetermined condition (time t28). Light up. Similarly, in the interlocking lighting devices 201 and 202, the drive circuit 220 turns on the light source 30 when the electric power input to the connection terminal unit 210 satisfies a predetermined condition (time t28). At time t29 when the lighting time P2 has elapsed from time t27, the control circuit 161 of the first lighting control device 11A turns off the light source 30 and further turns off the power supply circuit 140. As a result, in the interlocking lighting devices 201 and 202, electric power is not supplied to the connection terminal portion 210, so that the drive circuit 220 ends its operation and the light source 30 is turned off. At time t30 when the lighting time P2 has elapsed from time t28, the control circuit 161 of the second lighting control device 11B turns off the light source 30.

At time t31, when the detection signal is output from the sensor 40 of the second lighting control device 11B, the control circuit 161 of the second lighting control device 11B executes the lighting function and lights the light source 30. Further, the control circuit 161 of the second lighting control device 11B turns on the power supply circuit 140 for the lighting time P2 that is equal to or longer than the predetermined time so that the power output from the interlocking terminal unit 130 satisfies the predetermined condition. Accordingly, the interlocking terminal unit 130 of the first lighting control device 11A receives the power output from the interlocking terminal unit 130 of the second lighting control device 11B. Here, since the interlocking function is effective in the first lighting control device 11A, the control circuit 161 turns on the light source 30 at the time when the power input to the interlocking terminal unit 130 satisfies the predetermined condition (time t32). Let Similarly, in the interlocking lighting devices 201 and 202, the drive circuit 220 lights the light source 30 when the electric power input to the connection terminal unit 210 satisfies a predetermined condition (time t32). At time t33 when the lighting time P2 has elapsed from time t31, the control circuit 161 of the second lighting control device 11B turns off the light source 30 and further turns off the power supply circuit 140. As a result, in the interlocking lighting devices 201 and 202, electric power is not supplied to the connection terminal portion 210, so that the drive circuit 220 ends its operation and the light source 30 is turned off. At time t34 when the lighting time P2 has elapsed from time t32, the control circuit 161 of the first lighting control device 11A turns off the light source 30.

In particular, the present embodiment is effective when it is desired to continuously light the light source 30 by only one of the first lighting control device 11A and the second lighting control device 11B. For example, by operating the switch 61 to generate the second event, the first lighting control device 11A executes the continuous lighting process by the first function, and the second lighting control device 10B disables the interlocking function by the second function. To do. On the contrary, by operating the switch 62 to generate the second event, the second lighting control device 11B executes the continuous lighting process by the first function, and the first lighting control device 11A disables the interlocking function by the second function. To Therefore, the light source 30 can be continuously turned on only by the desired lighting control device 11.

1.2.3 Summary According to the lighting control system of the present embodiment, similarly to the first embodiment, the setting of the interlocking operation between the lighting control devices 11A and 11B is changed by the wiring between the lighting control devices 11A and 11B. Can be done without modification. Secondly, it is possible to change the setting of the interlocking operation between the lighting control devices 11A and 11B by using the existing configuration (interlocking terminal unit 130). In other words, the lighting control system of the present embodiment executes the same lighting control method as that of the first embodiment. Therefore, the setting of the interlocking operation between the lighting control devices 11A and 11B can be changed without changing the wiring between the lighting control devices 11A and 11B. Secondly, it is possible to change the setting of the interlocking operation between the lighting control devices 11A and 11B by using the existing configuration (interlocking terminal unit 130).

Moreover, in the lighting control device 11 of the present embodiment, the control circuit 161 has a first function and a second function. The first function includes a notification function of controlling the power supply circuit 140 in response to the occurrence of the second event and outputting electric power that does not satisfy the predetermined condition from the interlocking terminal unit 130. The second function is a function of performing an invalidation process for invalidating the interlocking function when the determination circuit 150 determines that the power input to the interlocking terminal unit 130 does not satisfy the predetermined condition. Therefore, by causing the second event to occur only in the desired lighting control device 11 among the plurality of lighting control devices 11, a plurality of lighting is performed so that another lighting control device 11 does not interlock with the desired lighting control device 11. The setting of interlocking between the control devices 11 can be changed.

2. Modifications The first and second embodiments described above are only a part of various embodiments of the present invention. Further, the first and second embodiments can be variously modified according to the design and the like as long as the object of the present invention can be achieved. The modifications of the first and second embodiments are listed below.

The lighting control system may include three or more lighting control devices (10, 11). The lighting control system does not necessarily have to include the interlocking lighting device 20. In short, the lighting control system only needs to include a plurality of lighting control devices.

The power feeding circuit 140 may include first and second switches electrically connected between the first and second power supply terminals 111 and 112 and the first and second interlocking terminals 131 and 132. The first and second switches are not limited to contactless switches such as triacs, but may be contact switches such as relays. Further, the power feeding circuit 140 is configured to apply a voltage different from the voltage between the first and second power supply terminals 111 and 112 to the first and second interlocking terminals 131 and 132 according to the interlocking lighting device 20. May be.

The configuration of the determination circuit 150 is an example and is not particularly limited. In short, the configuration of the determination circuit 150 is not particularly limited as long as it can determine whether or not the power satisfies a predetermined condition.

The configuration of the control circuit (160, 161) is an example and is not particularly limited. The control circuit (160, 161) may be any circuit that can realize the above-mentioned lighting function, interlocking function, first function, and second function.

In the lighting function, the first event may be reception of a predetermined signal from an external device, for example. The first event may be that the scheduled time has come. Further, in the lighting function, the lighting process may be continued until the end of the lighting process is instructed instead of the predetermined lighting time P2. Similarly, in the interlocking function, the control circuit (160, 161) may continue lighting the light source 30 until it is instructed to end the lighting of the light source 30 instead of the predetermined lighting time P2. In addition, in the lighting function, the time (period) for turning on the light source 30 and the time (period) for turning on the power feeding circuit 140 may or may not be equal.

In the first function, the second event may be reception of a predetermined signal from an external device, for example. The second event may be that the scheduled time has come. Further, in the modification of the second embodiment, the predetermined pattern of the second event is not limited to the electric power input to the power supply terminal unit 110 becoming 0 only during the period within the predetermined time range. For example, the predetermined pattern may be that the power of the power supply terminal unit 110 has exceeded 0 or exceeded a predetermined value multiple times within a predetermined period. In short, it suffices that the predetermined pattern be distinguishable from the pattern of electric power input from the power supply 50 to the power supply terminal unit 110 during normal operation.

In the notification process, the control circuit (160, 161) turns on the power supply circuit 140 for a time P1 shorter than the predetermined time so that the power output from the interlocking terminal unit 130 does not satisfy the predetermined condition. In other words, the control circuit (160, 161) causes the interlocking terminal unit 130 to generate a pulse in the notification process. In a modification, the control circuit (160, 161) may reduce the voltage between the interlocking terminal units 130 for a certain period in the notification process so that the power from the interlocking terminal unit 130 does not satisfy the predetermined condition. In another modification, the control circuit (160, 161) changes the phase of the voltage between the interlocking terminal units 130 in the notification process, so that the power from the interlocking terminal units 130 does not satisfy the predetermined condition. Good. In short, in the notification process, the interlocking terminal unit 130 may output electric power that does not satisfy the predetermined condition.
