Description

  The present invention relates to a method for assigning an individual address to each device such as a lighting fixture, a human sensor, an illuminance sensor, and a wall switch that are connected by a communication network and constitute the lighting control system in the lighting control system.

  For example, it is composed of a plurality of lighting fixtures and a control unit, bidirectional communication is performed between the lighting fixtures and the control unit via signal lines, and the lighting fixtures are controlled by command signals addressed to individual addresses from the control unit. In the lighting control system, when the address setting start signal is transmitted from the control unit and the lighting fixture receives this address setting start signal, the operation shifts to the address setting priority mode operation, and the address setting is performed without turning on / off the lamp. Only the command signal is received and the system is ready for operation. Thereafter, when a specific lighting fixture for setting the individual address is recognized, the individual address is assigned by the control unit. (For example, refer to Patent Document 1.)

Japanese Patent No. 3914622 (paragraph "0027")

  According to the conventional address setting method, at the time of installing the lighting fixtures or the like, an address for identifying each lighting fixture is assigned by an address setting command signal from the control unit. When it is exchanged, it is necessary to assign an individual address to the newly installed lighting fixture using the controller. However, since the controller may be connected and used only at the time of address setting or may communicate wirelessly, it is not always available at the fixture replacement site. May not be reset.

  The present invention has been made to solve the above-described conventional problems, and provides an address setting method for a lighting control system capable of automatically assigning an address by a simple operation even when replacing a lighting fixture or the like. Objective.

  In the address setting method of the present invention, when replacing the lighting fixture, if the power supply of the communication unit is activated, a new individual address that is not used is assigned to the newly installed lighting fixture. Set the group number to. When the power supply of the communication unit is cut off at the time of replacement, the same individual address as that of the lighting fixture before replacement is assigned to the newly installed lighting fixture at the time of power activation.

  According to the present invention, since the address of the replaced luminaire is automatically set by turning on or off the power of the communication unit to which the luminaire is connected, an operating device for setting the address is not necessary. The burden on the worker is also significantly reduced.

Individual addresses serving as reference numbers can be assigned in advance to each of the human sensor 4, the illuminance sensor 5, and the wall switch 6, and data setting, monitoring, and control can be performed individually.

  FIG. 2 is a block diagram showing the configuration of the communication unit.

  The communication unit 2 includes a wireless communication unit 14 that performs bidirectional communication with the wireless remote controller 7 and the like by wireless signals, a wireless data conversion unit 15 that converts data transmitted and received by the wireless communication unit 14, and a wireless data conversion unit 15 A calculation unit 16 that analyzes data to be converted, a wired serial conversion unit 17 that converts the data analyzed by the calculation unit 16 into wired serial data, a lighting fixture 3, a human sensor 4, an illuminance sensor 5, and a wall At least one of the switches 6 is connected, a wired serial connection unit 18 that transmits and receives wired serial data converted by the wired serial conversion unit 17, and a storage unit that stores setting values from the result of data analysis by the calculation unit 16 19 and an LED display unit 20 for displaying the result of data analysis by the calculation unit 16.

  When the communication unit 2 receives data setting, monitoring, and control signals of a wireless signal from the controller 1, the wireless data conversion unit 15 receives the data by the wireless communication unit 14 and can perform data analysis by the calculation unit 16. To convert to wired serial data. If the received data includes a set value, the set value is stored in the storage unit 19 and the LED display unit 20 displays an operation with the LED color or blinking state. The received data is converted into a signal for two-wire wired serial communication by the wired serial data conversion unit 17, and the luminaire 3, the human sensor 4, and the illuminance sensor 5 connected to the subordinate from the wired serial connection unit 18. The data is transmitted to the wall switch 6.

  When the communication unit 2 receives data from the lighting fixture 3, the human sensor 4, the illuminance sensor 5, and the wall switch 6, the data received by the wired serial connection unit 18 is serialized by the wired serial data conversion unit 17. The data is converted into data, the data is analyzed by the calculation unit 16, the received data is stored in the storage unit 19, and the operation state is displayed on the LED display unit 20. The received data is converted into wireless communication data by the wireless data conversion unit 15, and the data is transmitted from the wireless communication unit 14 to the controller 1.

  For data transmission / reception, for example, an operation command for turning on / off the lighting unit 3 from the communication unit 2, a monitor signal such as a dimming rate at which each lighting unit 3 is operating, and an individual address are assigned to each lighting unit 3 Similarly, for the address setting signal, transmission data is created or analyzed by the calculation unit 16 based on the data in the storage unit 19 of the communication unit 2, and is transmitted from the wired serial connection unit via the wired serial data conversion unit 17. Send and receive data. Each signal is provided with a function code that indicates the type of signal, and the receiving device analyzes the function code to determine the type of data, and grasps the numerical value received along with the function code and operates according to the command. Do.

  FIG. 3 is a block diagram showing the configuration of the controller 1. The controller 1 manages the plurality of communication units 2 and assigns individual addresses to each device such as the lighting fixture 3, the human sensor 4, the illuminance sensor 5, and the wall switch 6 connected under the communication unit 2. And the address of the communication unit 2 are managed by the storage unit 19. When data is transmitted from the controller 1 to each device, the data generated by the calculation unit 16 is converted into a wireless signal by the wireless data conversion unit 15 and transmitted from the wireless communication unit 14 to one or a plurality of communication units 2. . If data is received from the communication unit 2, the data received by the wireless communication unit 14 is converted into a serial signal by the wireless data conversion unit 15, data processing is performed by the calculation unit 16, and if there is setting data, Save in the storage unit 19. Further, the operation state of the area controller 1 is displayed on the LED display unit 20. The controller 1 has a memory compared to the communication unit 2 in order to manage all setting data and control states of the luminaire 3, the human sensor 4, the illuminance sensor 5 and the wall switch 6 connected to the plurality of communication units 2. The capacity needs to be large.

  The wireless remote controller 7 includes a display screen and operation buttons, and determines and transmits setting values by operating the buttons. In addition, the wireless remote controller 7 receives the operation state as monitor data, and thereby the data value is displayed on the display screen. It has a function to display.

  In this system, each of the plurality of lighting fixtures 3, the human sensor 4, the illuminance sensor 5, and the wall switch 6 is grouped, and a group number is set for each group, so that the same group is set. The devices operate in conjunction with each other, and each data setting, monitor, and illumination control can be performed on the group number.

  That is, when the lighting fixture 3, the human sensor 4, the illuminance sensor 5, and the wall switch 6 are grouped and further set with a group number, all the devices connected under the communication unit 2 with the wireless remote controller 7 are used. The individual address data is received, and one of the lists displayed on the display screen of the wireless remote controller 7 is selected on the screen. In the case of the luminaire 3, the selected device performs dimming operation, and in the case of the human sensor 4, the illuminance sensor 5, and the wall switch 6, the LED lighting display is performed. Make sure. With the arbitrary device selected, the controller 1, the communication unit 2, and the selected device store the group number by transmitting data indicating the group number from the wireless remote controller 7.

  The controller 1 manages the combination of the group number and the individual address of each device. For each group, the setting of control for turning on / off and dimming the lighting fixture 3 depending on the presence / absence of the person detected by the human sensor 4 The lighting fixture 3 is turned on / off and dimmed according to the brightness of the room detected by the illuminance sensor 5, and the lighting fixture 3 is turned on / off and dimmed by pressing each button of the wall switch 6. The setting of the function to be performed is collectively managed by storing it in the storage unit 19, and the operation state of each connected device is managed by periodically monitoring the operation state of each device.

  FIG. 8 is a flowchart showing the operation of the communication unit 2 in this system. S1 indicates that the communication unit 2 is powered off and is not operating. Next, in S2, the power supply of the communication unit 2 is switched to the ON state, whereby the initial setting in S3 is started. As an initial setting, the communication unit 2 confirms the current connection state by detecting the individual addresses of all the connected lighting fixtures 3 in S4. In the detection method, the communication unit 2 transmits a signal for monitoring the MAC address with the individual addresses from the individual address 1 to the maximum connection number 60 in order. The lighting fixture 3 that has received the monitor signal returns its own MAC address, and the communication unit 2 determines that only the lighting fixture 3 that has returned the MAC address is connected. The communication unit 2 stores the combination data of the individual address and the MAC address of the connected lighting fixture 3 in the storage unit 19. In S1, the individual address and MAC address of the luminaire 3 connected before the communication unit 2 is turned off are stored in the storage unit 19, but the unused individual address detected this time in S4 is In step S5, the MAC address is deleted to make it free.

  Next, in S6, the luminaire 3 for which the individual address is not set is detected. The lighting fixture 3 in which the individual address is not set transmits its own MAC address to the communication unit 2 to notify that the individual address is not set. When the lighting fixture 3 for which the individual address is not set is not detected, the initial setting is ended in S10. When the lighting apparatus 3 with no individual address set is detected, the communication unit 2 uses the data of the individual address stored in the storage unit 19 to send a signal for setting an empty individual address in S7. It transmits with respect to the lighting fixture 3. FIG. At this time, the individual address having the smallest numerical value is used among the individual addresses in the empty state. When there are a plurality of lighting fixtures 3 for which individual addresses are not set, the setting is performed in ascending order of numerical values of the MAC addresses.

  In S8, it is determined whether the group number corresponding to the individual address set in S7 is stored in the storage unit 19 of the communication unit 2. If there is a luminaire 3 connected before the communication unit 2 is turned off in S1, the set group number, individual address and MAC address are stored in combination in the storage unit 19 of the communication unit 2. Has been. If the group number is stored in the communication unit 2 in combination with the individual address set in S7, a group number setting signal is transmitted to the lighting device 3 of the corresponding individual address in S9, and the initial in S10. Setting is complete. At this time, the combination of the group number and the individual address may use data stored in the storage unit 19 of the controller 1 and transmit a group number setting signal from the controller 1. If the corresponding group number is not stored, the initial setting ends in S10 without setting the group number.

  Therefore, when the communication unit 2 is turned off in S1 and the group number is set, if the lighting fixture 3 is replaced in the power-off state after S1, the power is turned on in S2, and then in S7. The same individual address as the removed instrument is set, and the same group number is set in S9.

  After the initial setting is completed in S10, it is detected in S6A whether the luminaire 3 for which the individual address is not set is connected. The lighting fixture 3 connected to the communication unit after completion of the initial setting transmits its own MAC address to the communication unit 2 to notify that the individual address is not set. The communication unit that has received the notification sets a vacant individual address to the unset luminaire 3 through S7A. If there is no lighting fixture 3 for which an individual address has not been set in S6A, S6A is repeated to continue detection of the lighting fixture 3 for which no setting has been made.

Accordingly, when the lighting unit 3 is replaced when the communication unit 2 is turned on and the initial setting is completed, the communication unit 2 assigns an individual address that has not been used before S1. Since there is no corresponding individual address data in the storage unit 19 of the communication unit 2, the communication unit 3 does not transmit a group number setting signal.

  FIG. 4 shows a block diagram when the luminaire is replaced with a new luminaire, for example, and shows the operation when the luminaire 3-B is replaced in a state where the power of the communication unit 2 is cut off. Individual address 1 is assigned to the luminaire 3-A, individual address 2 is assigned to the luminaire 3-B, and individual address 3 is assigned to the luminaire 3-C. All three units are grouped as a group number ( 1) is set.

  When the lighting unit 3-B is removed from the communication unit 2 and the lighting unit 3-D is newly connected to the communication unit 2 in a state where the power source of the communication unit 2 is cut off, The individual address 2 set in the lighting fixture 3-B before the replacement is assigned to the lighting fixture 3-D.

  The communication unit 2 assigns the individual address, and at the same time, based on the database managed by the communication unit 2, the group number corresponding to the individual address set in the luminaire 3 before replacement is newly assigned to the luminaire 3 Has the ability to reset. Therefore, the group number (1) corresponding to the individual address 2 set in the previously installed lighting fixture 3-B is automatically set in the lighting fixture 3-D. Thereby, the lighting fixture 3-D after replacement | exchange is controlled similarly to the lighting fixture B before removing, without resetting a group number.

  That is, when the operator wants to reproduce the control state before replacement after replacement of the lighting fixture, it can be realized by replacing the communication unit 2 with the power supply OFF.

  FIG. 5 shows a block diagram when a plurality of lighting fixtures 3 are replaced at the same time while the communication unit 2 is powered off. Individual address 1 is assigned to the lighting fixture 3-A, individual address 2 is assigned to the lighting fixture 3-B, individual address 3 is assigned to the lighting fixture 3-C, and individual address 4 is assigned to the lighting fixture 3-D. The group number (1) is set as the same group for the fixture 3-A and the lighting fixture 3-B, and the group number (2) is set as the same group for the lighting fixture 3-C and the lighting fixture 3-D. ing.

  With the power supply of the communication unit 2 turned off, the two lighting fixtures 3-B and 3-C are removed, the lighting fixtures 3-E and 3-F are newly connected, and the power supply of the communication unit 2 is activated. Then, the two individual addresses used for the two units that have been removed are assigned to the newly installed lighting fixtures 3 and are assigned in ascending order of the serial numbers of the MAC addresses written in the manufacturing factory at the time of manufacture. In this case, for example, if a lighting fixture 3-E having a MAC address of 110009 and a lighting fixture 3-F having a MAC address of 110012 are newly installed, the individual address 2 is assigned to the lighting fixture 3-E. Individual address 3 is automatically assigned to 3-F.

  The communication unit 2 has a function of assigning an individual address and setting a group number corresponding to the individual address of the lighting fixture 3 before replacement based on the database managed by the communication unit 2. Therefore, since the group numbers previously set for the lighting fixtures 3-B and 3-C are set to the newly installed lighting fixtures 3-E and 3-F as they are, the lighting fixture 3- A group number (1) is automatically set for E, and a group number (2) is automatically set for the lighting fixture 3-F.

  Thus, when exchanging a plurality of lighting fixtures 3 at the same time, since the individual address and group number to be allocated change depending on the size of the MAC address of the lighting fixture 3, the exchange operator can change the MAC address of the lighting fixture 3 before the replacement. It is necessary to grasp the MAC address of the lighting fixture 3 to be newly installed, and the replacement lighting fixture 3 has a MAC address on the product nameplate attached to the outer surface so that the replacement worker can judge from the appearance. It is necessary to display it.

  FIG. 6 shows a block diagram when the luminaire 3 is replaced, and shows a case where the luminaire 3-B is replaced while the power source of the communication unit 2 is activated. Individual address 1 is assigned to the lighting fixture 3-A, individual address 2 is assigned to the lighting fixture 3-B, and individual address 3 is assigned to the lighting fixture 3-C, and all three of them are set to the group number (1). Yes.

  When the lighting device 3-B is removed and the lighting device 3-D is newly connected while the power source of the communication unit 2 is activated, the communication unit 2 detects that the lighting device 3-D is newly connected. Then, the individual address 4 that has not been used is assigned to the lighting fixture 3-D.

  In this case, since the individual address No. 4 is unused, the group number is not set in the database managed by the communication unit 2, and the group number is not automatically set in the replaced lighting fixture 3-D.

  That is, after the operator replaces the luminaire 3, if it is desired to set a new group number without reproducing the control state before the replacement, the communication unit 2 may be switched on and replaced. Thereafter, the operator sets a new group number using the wireless remote controller 7, and thereafter, control can be performed with a new group configuration.

  FIG. 7 shows a case where a plurality of lighting fixtures 3 are replaced at the same time while the power supply of the communication unit 2 is activated. Individual address 1 is assigned to the lighting fixture 3-A, individual address 2 is assigned to the lighting fixture 3-B, individual address 3 is assigned to the lighting fixture 3-C, and individual address 4 is assigned to the lighting fixture 3-D. -A and 3-B are set to group number (1), and lighting fixtures 3-C and 3-D are set to group number (2).

  In the state where the power supply of the communication unit 2 is activated, when the two lighting fixtures 3-B and 3-C are removed and the lighting fixtures 3-E and 3-F are newly connected, they have not been used until then. Individual addresses 5 and 6 are assigned in ascending order of MAC addresses. In this case, for example, if the lighting fixture 3-E with the MAC address 110009 and the lighting fixture 3-F with the MAC address 110012 are newly exchanged, the lighting fixture 3-E has the individual address No. 5, Individual address 6 is automatically assigned to 3-F.

  In this case, since the individual addresses No. 5 and No. 6 are unused, no group number is set in the database managed by the communication unit 2, and the group number is not automatically set. Therefore, the size of the MAC address does not affect the group number, and an arbitrary group number can be set and operated for a new lighting fixture by the operator's operation.

  Similarly to the automatic setting method of the individual address and group number of the lighting fixture 3, when the human sensor 4, the illuminance sensor 5 and the wall switch 6 connected to the communication unit 2 by a two-wire wired serial signal are replaced. The setting method is similarly switched depending on the power supply state of the communication unit 2.

  FIG. 9 shows a system configuration in which data transmission / reception between the controller 1 and the communication unit 2 is performed by wired serial communication.

An object is to maintain communication quality by connecting by wire serial communication between the controller 1 and the communication unit 2 when wireless communication is impossible due to a shield or the like. As a result, it is possible to configure a system with only a wired connection. In addition, the wireless remote controller 7 is also configured by a wired remote controller that transmits and receives data by wired connection.
A system constructed entirely by wired communication can be realized.

  FIG. 10 shows a system configured by installing a gateway 8 and a central management device 9 connected to each other on the upper side of the controller 1. An object is to collectively control a plurality of controllers 1 for managing the setting and control state of a system located below the communication unit 2 by a central management device 9 provided with a personal computer and a liquid crystal screen. The interface of the central management device 9 is a LAN, and can be linked with other equipment such as an air conditioner. The gateway 8 has a wired serial communication and LAN conversion function to which a plurality of controllers 1 are connected, and transmits and receives data.

  The central management device 9 can monitor the control state of each device such as the lighting fixture 3, the human sensor 4, the illuminance sensor 5, and the wall switch 6 connected under the communication unit 2 in real time on the screen. It is possible to set data such as the target dimming rate and to monitor the control state, and to perform operations such as turning on / off and changing the dimming rate on the screen.

  In addition, the central management device 9 can also display a trend display of the lighting fixture 3 on / off state on the screen, the detection state of the human sensor 4, and the illuminance value of the illuminance sensor 5 over time. With the monitor screen, it is possible to easily confirm the temporal change of the illumination state.

  FIG. 11 shows a block diagram in the case where the controller 1 is equipped with an upper-side wired serial data conversion unit 21 and an upper-side wired serial connection unit 22 that communicate with the upper system. The wireless communication data received from the wireless communication unit 14 is converted into a serial signal by the wireless data conversion unit 15, and data to be transmitted to the upper gateway is created based on the data received by the calculation unit 16, and the upper side wired serial data The conversion unit 21 converts the signal into a higher-level wired serial signal, and transmits the signal from the higher-level wired serial connection unit 22 to the gateway.

  When a wired serial signal is received from the upper gateway 8, the serial signal for transmitting the data received by the upper wired serial connection unit 22 to the arithmetic unit 16 by the upper wired serial data conversion unit 21. Convert to The transmission data is converted into wireless communication data by the wireless data conversion unit 15 according to the processing result, and the wireless data is transmitted from the wireless communication unit 14 to the communication unit 2.

  FIG. 12 shows a method for realizing the present system by incorporating the control unit 10 capable of wired serial communication in the lighting fixture 3. The lighting fixtures 3-A and 3-B incorporate a control unit 10 that performs serial communication with the inverter 11 and the communication unit 2 for lighting the lamp 12 at high frequency.

  Even in the inverter 11 having no wired serial communication function, the built-in control unit 10 transmits / receives data to / from the communication unit 2 by wired serial communication, and the control unit 10 transmits a PWM signal that changes the brightness of the inverter 11. Thus, it is possible to realize commands for turning on / off and dimming control from the controller 1.

  By incorporating the control unit 10 in the existing lighting fixture 3, in the lighting fixture 3 with various types depending on the inverter 11, the lamp 12, and the housing shape, a circuit having an interface function with wired serial communication is newly added to the inverter 11. This system can be realized at low cost without adding to the above.

Embodiment 2. FIG.
The present embodiment is different from the address setting method of the lighting control system shown in the first embodiment in the method of switching individual addresses to be assigned.

  In the present embodiment, the same components as those shown in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  The address setting method according to this embodiment will be described with reference to FIG.

  FIG. 13 is a block diagram showing the configuration of the present embodiment. A switching unit 13 is mounted on the communication unit 2 in a system composed of a lighting unit 3, a human sensor 4, an illuminance sensor 5, and a wall switch 6 connected to the communication unit 2 by two-wire wired serial communication. . When a connection device such as the lighting fixture 3 is replaced, by switching the state of the switching button 13 mounted on the communication unit 2, it is possible to select the individual address of the device to be replaced and newly installed.

  For example, when the switching button 13 of the communication unit 2 is set to the A state and the lighting fixture 3 is exchanged, the individual address set in the removed lighting fixture 3 is also assigned to the newly installed device. Therefore, the operation is the same as that of FIGS. 4 and 5, and the group number corresponding to the individual address is set based on the data stored in the storage unit 19 of the communication unit 2, so that the setting state before replacement can be reproduced. .

  In addition, when the switching button 13 of the communication unit 2 is set to the B state and the luminaire 3 is exchanged, it is not the individual address set for the removed luminaire 3, but a new individual that has not been used until now. Assign an address. Therefore, the operation is the same as that shown in FIGS. In this case, the group number is not set.

  FIG. 14 is a flowchart showing the operation of the communication unit 2 in the present embodiment, and shows the operation up to the end of the initial setting in S110. In S101, the power supply of the communication unit 2 is turned off, and in S102, the power supply of the communication unit 2 is switched to the ON state, whereby the initial setting in S103 is started.

  Next, in S106, the luminaire 3 for which the individual address is not set is detected. If an unset lighting fixture 3 is not detected, the initial setting is terminated in S110. When the lighting fixture 3 for which the individual address is not set is detected, the state of the switching button 13 mounted on the communication unit 2 is detected in S111. When the switching button 13 is in the A state, the communication unit 2 detects the individual addresses of all connected lighting fixtures 3 in S104, thereby confirming the current connection state. The detection method is the same as S4 in FIG. In S101, the MAC address, the individual address, and the group number of the lighting fixture 3 connected before the power of the communication unit 2 is turned off are stored in the storage unit 19 of the communication unit 2, but this time detected in S104. For an unused individual address, the MAC address is deleted in S105 to make it empty. On the other hand, if the switching button 13 is not in the A state but in the B state in S111, the connection state is not confirmed.

  In S107, an individual address is set for the luminaire 3 for which no address is set. The setting method is the same as S7 in FIG. 8, but when the switch button 13 is in the A state in S111, the data of the unconnected lighting fixtures is deleted in S105, so that the individual items that are in the empty state are deleted. Set the address. If the switching button 13 is in the B state in S111, since the unconnected luminaire data has not been deleted, an individual address that has not been used since S101 is set.

  In S108, it is determined whether or not the group number corresponding to the individual address set in S107 is stored in the storage unit 19 of the communication unit 2, and the lighting connected before the communication unit 2 is turned off in S101. When there is the fixture 3, it is detected in S108 that the individual address and the group number are stored in the storage unit 19 of the communication unit 2 in S108, and in S109, the group number is assigned to the lighting fixture 3 of the corresponding individual address. In step S110, the initial setting is completed. If the corresponding group number is not stored, the initial setting ends in S110 without setting the group number.

  Therefore, when the lighting fixture 3 is connected before the power of the communication unit 2 is turned off in S101 and the group number is set, if the lighting fixture 3 is replaced in the power-off state after S101, the power ON of S102 is turned on. Later, in S106, it is detected that a new fixture has been attached, and when the state of the switching button 13 detected in S111 is A, the same individual address and group number as the removed lighting fixture 3 are set, and the B state In this case, a new individual address that is not used is set.

  FIG. 15 is a flowchart showing the operation of the communication unit 2 in the present embodiment, and shows the operation after the initial setting in S110. After completion of the initial setting, the lighting apparatus 3 for which the individual address is not set is detected in S106A. When the unset lighting fixture 3 is not detected, S106A is repeated, and the detection of the lighting fixture 3 with the individual address not set is continued.

  When the lighting fixture 3 with no address set is detected in S106A, the state of the switching button 13 mounted on the communication unit 2 is detected in S111A. When the switching button 13 is in the A state, the communication unit 2 detects the individual addresses of all the connected lighting fixtures 3 in S104A, thereby confirming the current connection state. When the luminaire 3 is replaced after the initial setting of S110, the MAC address, the individual address, and the group number of the removed luminaire 3 are stored in the storage unit 19 of the communication unit 2, but are not detected this time in S104A. For the individual address used, the MAC address is deleted in S105A to make it empty. On the other hand, when the switching button 13 is not in the A state but in the B state in S111A, the connection state is not confirmed.

  In S107A, an individual address is set in the same manner as S107 in FIG. If the switching button 13 is in the A state in S111A, since the data of the unconnected lighting fixture is deleted in S105A, an individual address that is in an empty state is set. If the switching button 13 is in the B state in S111A, since the unconnected luminaire data has not been deleted, an individual address that has not been used before the luminaire 3 is replaced is set.

  Next, in S108A, it is determined whether the group number corresponding to the individual address set in S107A is stored in the storage unit 19 of the communication unit 2, and if it is stored, the corresponding group number is set in S109A. , The operation returns to S106A. If the corresponding group number is not stored, the process returns to the operation of S106A without setting the group number, and the detection of the luminaire with the individual address not set is repeated.

  Therefore, when the luminaire 3 is replaced after completion of the initial setting in S110, the same individual address and group number as the removed luminaire 3 are set according to the state of the switching button 13, or a new individual address that has not been used so far. Can be arbitrarily selected.

  Even if the power supply state of the communication unit 2 cannot be easily changed at the time of replacement of the lighting fixture 3 according to the present embodiment, the illumination can be removed by setting the switching button 13 mounted on the communication unit 2 to the A state. The same individual address and group number as those of the appliance 3 can be set, and the setting state before replacement can be easily reproduced.
