Description

  The present invention relates to a lighting system that performs dimming control of a plurality of lighting fixtures.

  Generally, in a hotel banquet hall or a large meeting room, a room may be divided into a plurality of parts by using a partition according to the number of people. In such a use environment, control is often shared between a master unit that controls the lighting fixtures in the entire room and a slave unit that controls the lighting fixtures in the divided areas. Further, in this case, the master unit is used when a lighting device in the entire room is a control target and when a lighting device in a divided area including the master device is a control target (for example, Patent Document 1). reference).

  In the apparatus disclosed in Patent Document 1, a video display device that displays a dimming operation unit arrangement position and an illumination load arrangement position together with a dimming object space diagram on the operation panel, and a partition position in the dimming object space diagram are used. A dimming operation unit position and an input device for designating are mounted, and the partition position is input while viewing the video display.

  However, since the signal lines are individually wired from the master unit to each lighting fixture, there is a problem that the wiring work is complicated, and a lot of wires are necessary and the cost is high. There's a problem.

  As technologies for reducing the labor of wiring work, various technologies for associating switches and lighting fixtures using network technology in a space where a large number of lighting fixtures are arranged such as offices and stores have been proposed. For example, Japanese Patent Application No. 2002-218997 is a lighting control system that performs centralized control, and includes a configuration in which a centralized control device and a plurality of electronic ballasts that are terminals are connected via a two-wire signal line. Things are shown. The electronic ballast constitutes a luminaire together with the lamp, and the electronic ballast can control not only lighting load on / off but also dimming control. The centralized control device has a function of generating a control signal and sending it to the signal line, a function of receiving a signal returned from the electronic ballast through the signal line, and a function of evaluating the signal returned from the electronic ballast. I have. Further, the centralized control device can request the dimming of the electronic ballast through the signal line, and uses a serial digital signal as the control signal. The control signal includes a control command or illuminance information. In addition, when multiple electronic ballasts are arranged in one room, it is possible to give instructions to individually control electronic ballasts and to control multiple electronic ballasts as a group. It has become.

  A lighting control system using a distributed control system is also known as a device for controlling lighting equipment using network technology. For example, a unique address is set in advance for each node as a terminal where a lighting fixture is provided before wiring, the unique address is re-recognized between nodes after wiring, a unique address is set as an operation address, and the set unique address is used. Thus, there is one that allows the node to be selected intentionally when confirming the node installation position or the presence of the node in the group (for example, see Patent Document 2).

Furthermore, there is also known a configuration in which another operation can be performed by adding a switch or a sensor to a general lighting control system (for example, see Patent Document 3). This eliminates the need to make changes to the configuration of the lighting fixture in order to give the lighting fixture the ability to distinguish the signal from the sensor when notifying the lighting fixture of instructions from the sensor. When a signal registered in the lighting fixture in advance is used as a signal from the sensor without any change, it is impossible to determine whether the lighting fixture is a signal from the sensor from the signal from the original switch. It solves the problem of counter-operation. That is, in the lighting control system, a signal discriminating unit is added on the signal line between the switch or sensor and the lighting fixture. Judgment of priority. In this configuration, it is possible to operate the luminaire by distinguishing the instruction from the switch and the instruction from the sensor by determining the priority between the switch or sensor and the signal determination unit.

  By the way, in the lighting control system having a general configuration based on the centralized control system or the distributed control system described above, in a small space at the conference room level, a function that allows the user to freely change the room layout is realized. If you want to control the dimming level in units of (small rooms with room allocation), you need to send not only individual address information but also area information to manage each lighting fixture. There is a problem that the length becomes long and it takes time for communication. In addition, it is necessary to set area information for the switches and sensors belonging to each area, and the setting operation becomes complicated and the cost of system components increases.

  The present invention has been made in view of the above-mentioned reasons, and the purpose thereof is to easily associate a lighting fixture and a slave unit according to the way of dividing the space when the space is divided and used. In addition, an object of the present invention is to provide a lighting system that can provide a dimming level to a lighting fixture in a short time without separately accessing the lighting fixture.

According to the first aspect of the present invention, there are provided a plurality of luminaires whose dimming levels are instructed from the outside, a master unit that instructs the luminaires on the dimming level, and a dimming level change of the luminaires with respect to the master unit The lighting device has a zone address in units of zones including at least one lighting device, and the master unit has a plurality of scenes that are combinations of dimming levels in units of zones. The scenes that have the same set of zones are grouped together into a single pattern and a dimming scene setting table that stores multiple sets of patterns, and the scene is selected by the slave unit when any of the patterns is selected when an instruction to is made, associated with the scene by using a zone address corresponding to the scene included in the selected pattern in the dimmer scene setting table And a control unit providing a dimming level of each over on to the luminaire of each zone, the child device, characterized by comprising an operation unit for instructing the scene the parent device.

According to this configuration , each handset can select only the pattern scene set in the dimming scene setting table with a simple task of changing the pattern according to the way of dividing the space . It becomes possible to limit the control range of the luminaire by each slave according to the way of dividing the space. Further, since the slave unit has a simple configuration that only notifies the master unit of scene selection, the slave unit can be realized at low cost and the slave unit can be downsized. Furthermore, since the parent device manages the data related to the scene at once, the data related to the scene can be easily managed.

  According to a second aspect of the present invention, in the first aspect of the present invention, the slave unit includes a switch for selecting lighting and extinguishing of the lighting fixture, and the master unit is a scene before the extinguishing when the extinction is selected by the switch. And a scene storage unit that stores the scene stored in the scene storage unit when lighting is selected by a switch.

  According to this configuration, it is possible to switch between lighting and extinguishing with the switch, and it becomes possible to reproduce the scene before the extinguishing at the time of lighting. In addition, since the scene before the light is turned off can be reproduced without providing the storage unit in the slave unit, it is not necessary to operate the scene again when the light is turned on, and an improvement in function can be expected.

  According to a third aspect of the present invention, in the first aspect of the invention, an area dividing member used for dividing the space into a plurality of areas in which a plurality of areas including at least one zone are formed, and the area dividing member are provided. And a partition slave unit that detects how to divide the space, and the master unit corresponds to the partition method from the dimming scene setting table when notified of the partition method of the space from the partition slave unit. It is characterized by selecting a pattern.

It can be selected, and setting by the user is unnecessary, forgetting to set can be prevented, and a desired lighting environment is obtained, so that usability is improved.

  According to a fourth aspect of the present invention, in the first aspect of the present invention, a sensor for detecting a state associated with lighting and detecting a change in state, which gives a dimming level to the lighting fixture via the master unit, is set in units of the zone. When the state change is detected by the sensor, the master unit acquires a zone address of the lighting fixture associated with the sensor.

  According to this configuration, since the zone address is given not only to the lighting fixture but also to the sensor, the parent device can identify the sensor that is the transmission source with a signal having a short signal length. The lighting fixtures linked to the sensor state change are performed according to the dimming scene setting table stored in the storage unit of the master unit. It is possible to easily and inexpensively realize a scene linked to the state change.

According to a fifth aspect of the present invention, in the fourth aspect of the invention, when the sensor is a brightness sensor that detects illuminance, the master unit transmits a dimming level to the zone associated with the sensor. It is characterized by prohibition.

  According to this configuration, transmission of the dimming level from the master unit is prohibited for a lighting fixture that controls the light output so as to keep the illuminance constant in conjunction with the detection value of the brightness sensor. Therefore, it is performed by directly giving a dimming level from the brightness sensor to the lighting fixture, and the light output of the lighting fixture can be linked to the detection value of the sensor, and illumination is performed via the master unit. The load on the master unit is reduced as compared with the case of controlling the appliance. In particular, when a large number of detection values are continuously transmitted, such as the detection value of the brightness sensor, an effect of greatly reducing the signal processing load in the parent device can be expected.

According to a sixth aspect of the present invention, in the first aspect of the present invention, a plurality of the parent devices are provided and communicate with each other, and each parent device is managed by a dimming scene setting table in another parent device. If a zone managed by another master unit is specified from any master unit, the dimming level is given to the lighting fixture using the dimming scene setting table of the other master unit. To do.

  According to this configuration, when the spaces where the lighting fixtures managed by each master unit are arranged are connected, it becomes possible to give dimming levels to all the lighting fixtures from any master unit. Improves. In other words, it is possible to flexibly cope with the use of the space. In addition, instead of giving each parent unit the data corresponding to all the lighting fixtures, the dimming scene setting data held by other parent units is diverted, so there is no burden on the storage capacity of each parent unit, and comparison Can be constructed at a reasonable cost.

According to a seventh aspect of the present invention, in the first aspect of the present invention, the master unit includes a slave unit operation prohibition setting unit that prohibits a desired operation of the slave unit.

  According to this structure, the subunit | mobile_unit which functions effectively with respect to the lighting fixture in the divided | segmented area | region can be specified, and the operation by the subunit | mobile_unit which makes object another area | region can be prohibited.

According to the configuration of the present invention , each handset can select only the scene of the pattern set in the dimming scene setting table with a simple operation of changing the pattern according to the way of dividing the space. Therefore, it becomes possible to limit the control range of the lighting fixture by each slave unit according to the way of dividing the space. In addition, since the slave unit has a simple configuration that only notifies the master unit of scene selection, the slave unit can be realized at a low cost and the slave unit can be downsized. There is. Further, since the parent device manages data related to the scene in a batch, there is an advantage that the data related to the scene can be easily managed.

(Embodiment 1)
In this embodiment, as shown in FIG. 2, it is a room such as a banquet hall or a conference room, and can be divided into a plurality of spaces by providing partitions 5 as necessary. Assume that the present invention is applied to a large room. In the illustrated example, one room can be divided into up to three areas A1 to A3, and each area A1 to A3 can be further divided into two zones Z11, Z12, Z21, Z22, Z31, and Z32. Show. The left and right areas A1 and A3 shown in FIG. 2 can be divided into two upper and lower zones Z11, Z12, Z31, and Z32. The central area A2 can be divided into two inner and outer zones Z21 and Z22. In the room, lighting fixtures 3 having the same shape are arranged in a matrix with seven rows, and at least one lighting fixture 3 is included in each zone Z11, Z12, Z21, Z22, Z31, Z32. Zones Z11, Z12, Z21, Z22, Z31, and Z32 are set.

  Each luminaire 3 is connected to a signal line 4, and the signal line 4 is wired so as to connect each row of luminaires 3 in a straight line, and further connects each adjacent two rows of luminaires 3. One end of each straight signal line 4 is connected to each other. Therefore, all the lighting fixtures 3 in the room are connected to one meandering signal line 4. Each luminaire 3 has a function of controlling the light output when the dimming level is instructed through the signal line 4. Here, the dimming level is specified in the range of 0 to 100%, 100% of the dimming level means rated lighting (full lighting), and 0% of the dimming level means off. In addition, a dimming level greater than 0% and less than 20% is not used, and only a range of 20% or more is used when the lighting fixture 3 is turned on.

The dimming level of each lighting fixture 3 is instructed by operating the operation units 11 and 21 (see FIG. 1) including the switches SW1 and SW2 provided in the master unit 1 or the slave unit 2 connected to the signal line 4. Is done. Only one master unit 1 is provided in one room, and the number of slave units 2 is appropriately set according to the maximum number of areas A1 to A3 that can be provided in the room. The dimming level is controlled in units of zones Z11, Z12, Z21, Z22, Z31, and Z32, and the same dimming level is given to the luminaires 3 included in the zones Z11, Z12, Z21, Z22, Z31, and Z32. It is done. In the master unit 1, a plurality of combinations of dimming levels of the lighting fixtures 3 for each of the zones Z11, Z12, Z21, Z22, Z31, and Z32 are registered as “scenes”, and the operations of the master unit 1 and the slave unit 2 are performed. In sections 11 and 21 , a desired scene can be selected from scenes registered in base unit 1. That is, if one scene is selected by the operation units 11 and 21 of the master unit 1 or the slave unit 2, the dimming level of the selected scene is set in the luminaire 3 of each zone Z11, Z12, Z21, Z22, Z31, and Z32. Is given.

  As will be described later, the master unit 1 and the slave unit 2 of the present embodiment include one or more zones Z11, Z12, Z21, Z22, Z31, with zones Z11, Z12, Z21, Z22, Z31, and Z32 as a unit. The lighting fixture 3 included in the associated zones Z11, Z12, Z21, Z22, Z31, Z32 can be controlled. In the illustrated example, six zones Z11, Z12, Z21, Z22, Z31, and Z32 are formed, and two slave units 2 or two slave units 2 are provided in each of the areas A1 to A3. There are 6 units including the base unit 1 and the base unit 2.

  The master unit 1 and the slave unit 2 select five types of scenes: four types of scenes that turn on any lighting fixture 3 that is a control target, and scenes that turn off all lighting fixtures 3 that are control targets can do. The master unit 1 and the slave unit 2 are respectively provided with switches SW1 and SW2 including push button switches for selecting a scene, and one of five types of scenes can be selected by operating the switches SW1 and SW2. Select For example, by providing five switches SW1 and SW2 for selecting scenes in the master unit 1 and the slave unit 2, five types of scenes can be selected alternatively. Further, as shown in the example, four switches SW1 and SW2 for selecting a scene are provided for each of the master unit 1 and the slave unit 2 so that the four switches SW1 and SW2 are alternatively turned on. Then, four types of scenes for lighting any one of the lighting fixtures 3 to be controlled are selected in association with the switches SW1 and SW2, and the switches SW1 and SW2 are turned on when any of the four switches SW1 and SW2 is on. You may make it select the scene which turns off all the lighting fixtures 3 which the main | base station 1 or the subunit | mobile_unit 2 is making control object by turning off SW2.

  When five switches SW1 and SW2 are provided here, and one switch SW1 and SW2 is associated with turning off, it is desirable to use the switches SW1 and SW2 for switching between turning on and off. Further, when one switch SW1 and one switch SW2 are used for switching on / off in the main unit 1 and the sub unit 2, when the light-off operation is performed, the scenes S1 to S4 before the turn-off are stored in the main unit 1. It is desirable to provide a scene storage unit for storing the data. By adopting this configuration, it is possible to reproduce the scenes S1 to S4 before being turned off when switching from turning off to turning on by the switches SW1 and SW2 for switching on / off. In order to perform this operation, five switches SW1 and SW2 are required in each of the master unit 1 and the slave unit 2, but since the master unit 1 stores the scenes S1 to S4 before turning off, the slave unit 2 In this case, it is not necessary to store the scenes S1 to S4, and it is possible to add the above functions at a relatively low cost simply by changing the program for determining the operation of the master unit 1. Note that the scenes S1 to S4 can be selected by operating the switches SW1 and SW2 for selecting the scenes S1 to S4 when the lighting fixture 3 is turned off.

  By the way, in the master unit 1, the five types of scenes including the lights off described above are registered as a “pattern” as a set, and the type of scene that can be selected by the switches SW1 and SW2 is changed by selecting the pattern. be able to. The pattern is associated with the way of dividing the areas A1 to A3 by the partition 5, and the room is divided into three areas A1 to A2 by the pattern P1 that uses the whole room without using the partition 5 and the partition 5. A pattern P3, a pattern P3 in which the partition 5 is provided only between the areas A2 and A3, and a pattern P4 in which the partition 5 is provided only between the area A1 and the area A2 can be selected.

  In the pattern P1, both the parent device 1 and the child device 2 control the lighting fixtures 3 of all the zones Z11, Z12, Z21, Z22, Z31, and Z32 as the types of scenes. A scene S1 (A1A2A3-P1) in which the dimming levels given to the lighting fixtures 3 of Z11, Z12, Z21, Z22, Z31, and Z32 are 100%, 100%, 100%, 100%, 100%, and 20%, respectively. , Scene S2 (A1A2A3-P1) to be 100%, 100%, 100%, 100%, 20%, and 100%, respectively, and 30%, 30%, 100%, 100%, 100%, and 100%, respectively Scene S3 (A1A2A3-P1) and scene S4 (A1A2A3-P1) to be 30%, 100%, 30%, 100%, 30%, and 100%, respectively ) And, turned off each scene S5 with (A1A2A3-P1) is selectable. In the reference numerals in parentheses, the left side of the hyphen means the area name to be controlled, and the right side of the hyphen means the pattern name.

Further, in the pattern P2, the base unit 1 and the handset 2 is, their respective two portions of the zones Z11, Z12, Z21, Z22, Z31, the lighting apparatus 3 of Z32 to the control target. That is, in FIG. 2, the master unit 1 and the slave unit 2 provided in the area A1 are controlled by the lighting devices 3 included in the zones Z11 and Z12 of the area A1, and the two slave units 2 provided in the area A2 are The lighting fixtures 3 included in the zones Z21 and Z22 of the area A2 are controlled, and the two slave units 2 provided in the area A3 are the lighting fixtures 3 included in the zones Z31 and Z32 of the area A3. That is, five types of scenes can be selected for each of the areas A1 to A3 by the master unit 1 and the slave unit 2, and a total of 15 types of scenes are included in the pattern P2. For example, the master unit 1 and the slave unit 2 in the area A1 are scenes S1 (A1) in which only the lighting fixtures 3 in the zones Z11 and Z12 are controlled, and the dimming levels given to the lighting fixtures 3 are 100% and 100%, respectively. -P2), scene S2 (A1-P2) to be 100% and 100%, scene S3 (A1-P2) to be 30% and 30%, and scene S4 (30 to 100% respectively) A1-P2) and a scene S5 (A1-P2) that each turns off can be selected. Further, the handset 2 in the area A2 is set to scenes S1 (A2-P2) in which only the lighting fixtures 3 in the zones Z21 and Z22 are controlled, and the dimming levels given to the lighting fixtures 3 are 100% and 100%, respectively. 100% and 100% scene S2 (A2-P2), 100% and 100% scene S3 (A2-P2), and 30% and 100% scene S4 (A2-P2), respectively. And the scene S5 (A2-P2) to be turned off can be selected. Similarly, the slave unit 2 in the area A3 is a scene S1 (A3-P2) in which only the lighting fixtures 3 in the zones Z31 and Z32 are controlled, and the dimming levels given to the lighting fixtures 3 are 100% and 20%, respectively. 100% and 100% scene S2 (A3-P2), 30% and 30% scene S3 (A3-P2), and 30% and 100% scene S4 (A3-P2), respectively. ) And a scene S5 (A3-P2) that is turned off.

  The same applies to the other patterns P3 and P4. In the pattern P3, the master unit 1 and the slave unit 2 in the areas A1 and A2 control the lighting fixtures 3 in the zones Z11, Z12, Z21, and Z22, and the children in the area A3. The machine 2 controls the lighting fixtures 3 in the zones Z31 and Z32, and in the pattern P4, the master unit 1 and the slave unit 2 in the area A1 control the lighting fixtures 3 in the zones Z11 and Z12, and the area A2, The subunit | mobile_unit 2 of A3 makes the lighting fixture 3 of zone Z31 and Z32 control object. Accordingly, 10 types of scenes are included in each of the patterns P3 and P4.

  Table 1 shows an example of the relationship between the patterns P1 to P4, the scene, and the dimming levels of the zones Z11, Z12, Z21, Z22, Z31, and Z32. The relationship shown in Table 1 is registered in the master unit 1 as a dimming scene setting table, and when a desired pattern P1 to P4 is selected by the master unit 1 according to how the room is divided by the partition 5, the pattern P1 to P4 The specified scene can be selected by the master unit 1 and each slave unit 2.

  The parent device 1 and the child device 2 include communication units 12 and 13 connected to the signal line 4, respectively, and the operation of the operation unit 11 in the child device 2 is notified to the parent device 1 through the signal line 4. The lighting fixture 3 also includes a communication unit 32 connected to the signal line 4, and an instruction (dimming level) from the parent device 1 is transmitted to the lighting fixture 3. The communication units 12, 22, and 32 are configured by individual components or a dedicated integrated circuit. Further, addresses are set in the slave unit 2 and the lighting fixture 3 so that communication is possible between the master unit 1 and the specific slave unit 2 and between the master unit 1 and the specific lighting fixture 3. . The handset 2 and the lighting fixture 3 are provided with DIP switches for setting addresses, and the base unit 1 is provided with a storage unit 13 for storing addresses set in the handset 2 and the lighting fixture 3. Here, in the subunit | mobile_unit 2 and the lighting fixture 3, you may make it memorize | store an address using a non-volatile memory like EEPROM instead of a DIP switch. When address setting is performed using such a non-volatile memory, the master unit 1 uses the unique identifier (for example, the serial number of the product) given to the slave unit 2 and the lighting fixture 3 to set the slave unit 2. In addition, it is possible to individually communicate with the lighting device 3 and to set addresses corresponding to the site from the parent device 1 to the child device 2 and the lighting device 3.

As described above, since the lighting fixture 3 is controlled in units of the zones Z11, Z12, Z21, Z22, Z31, and Z32, it is not necessary to individually set an address for each lighting fixture 3, and each zone Z11, Z12, The same address is assigned to the luminaires 3 included in Z21, Z22, Z31, and Z32. Thus, since the same address is given to the lighting fixture 3 in units of zones Z11, Z12, Z21, Z22, Z31, and Z32, hereinafter, this address set in the lighting fixture 3 is referred to as a zone address. That is, when the base unit 1 accesses the lighting fixture 3 using the zone address, the lighting fixtures 3 in the zones Z11, Z12, Z21, Z22, Z31, and Z32 simultaneously receive the dimming level. Become. That is, even in the zones Z11, Z12, Z21, Z22, Z31, Z32 including a plurality of lighting fixtures 3, all the lighting fixtures 3 in the zones Z11, Z12, Z21, Z22, Z31, Z32 are provided. it is possible to provide a dimming level simultaneously concurrent, short time can indicate a dimming level in comparison with the case of transmitting the individual dimming level of each lighting apparatus 3, the operation unit 11, 21 of The light output of the lighting fixture 3 can be changed without delay from the operation.

As shown in FIG. 1, the base unit 1 includes a control unit 10 having a microcomputer (hereinafter abbreviated as “microcomputer”) in addition to the operation unit 11 and the communication unit 12. The storage unit 13 described above is attached. A nonvolatile memory such as an EEPROM is used for the storage unit 13 so that the contents can be rewritten, and the contents are not lost even during a power failure. The storage unit 13 also stores the above-described dimming scene setting table for associating operations of the operation units 11 and 21 provided in the master unit 1 and the slave unit 2 with the lighting state of the lighting fixture 3.

  In addition to the switch SW1, the operation unit 11 of the base unit 1 includes a light emitting diode (not shown) that indicates whether the lighting fixture 3 is turned on or off, and a liquid crystal display DP that can display characters. The switch SW1 is used when selecting a scene as described above, and is also used for selecting the patterns P1 to P4. Furthermore, it is also used to create a dimming scene setting table by operating the switch SW1 while confirming the display content of the liquid crystal display DP. In a state where the dimming scene setting table is stored in the storage unit 13, the master unit 1 is selected according to the contents of the dimming scene setting table by selecting the patterns P <b> 1 to P <b> 4 with the operation unit 11 provided in the parent unit 1. Since a scene that can be selected by the slave unit 2 is defined, the scene is instructed to the control unit 10 by the switch SW1 of the master unit 1 in this state, or controlled through the signal line 4 by operating the switch SW2 of the slave unit 2 When a scene is instructed to the unit 10, the control unit 10 refers to the dimming scene setting table in the storage unit 13 to thereby illuminate each zone Z11, Z12, Z21, Z22, Z31, Z32 corresponding to the scene. The dimming level of the fixture 3 is extracted, and the communication unit 12 is passed to the lighting fixture 3 using the zone address in units of the zones Z11, Z12, Z21, Z22, Z31, and Z32. The dimming level transmitted Te, adjusts the light output of the luminaire 3. The storage unit 13 may be built in the control unit 10.

  Similar to the parent device 1, the child device 2 includes a control unit 20 having a microcomputer as a main component in addition to the operation unit 21 and the communication unit 22. The operation part 21 of the subunit | mobile_unit 2 is provided with the light emitting diode which shows the lighting / extinguishing state of the lighting fixture 3 with several switch SW2. The switch SW2 can select a scene in the same manner as the switch SW1 of the parent device 1. When the switch SW1 is operated, the control unit 20 switches the parent device 1 together with the address of the child device 2 through the communication unit 22. Notify the operation contents of SW1. That is, when the operation unit 21 of the child device 2 is operated, information on the on / off state of the switch SW2 is transmitted to the parent device 1 together with the address of the child device 2, and which switch SW2 of which child device 2 is operated is determined as the parent device. Let 1 recognize. Since one of the patterns P1 to P4 is selected in the master unit 1, when the slave unit 2 and the switch SW2 are specified, the scene can be specified by referring to the dimming scene setting data. The dimming level for each zone Z11, Z12, Z21, Z22, Z31, Z32 in the scene is transmitted to each luminaire 3 using the zone address.

  By the way, the lighting fixture 3 is provided with the lighting circuit control part 30 which makes a microcomputer a main component in addition to the lamp 31 and the communication part 32, and the lighting circuit part 33 which makes the lamp 31 light. The lamp 31 is assumed to be a fluorescent lamp, and the lighting circuit unit 33 uses a lamp capable of dimming and lighting the fluorescent lamp according to an instruction from the lighting circuit control unit 30. For example, a lighting circuit unit 33 including an inverter circuit is used, and the lamp 31 is dimmed by controlling the power supplied from the inverter circuit to the lamp 31. The lighting circuit control unit 30 controls the lighting circuit unit 33 with the dimming level received from the parent device 2 through the communication unit 32.

  As described above, the patterns P1 to P4 associated with the way of dividing the room by the partition 5 are determined, and the lighting fixture 3 is adjusted for each of the patterns P1 to P4 in units of the zones Z11, Z12, Z21, Z22, Z31, and Z32. Since the combination of the light levels is defined as a scene, the position change of the partition 5 can be handled only by changing the patterns P1 to P4. Further, since the slave unit 2 only needs to transmit information about which scene is selected to the master unit 1, the operation content of the switch SW2 is simply transmitted to the master unit 1 through the signal line 4. Well, it can be made compact at a relatively low cost. Moreover, since the light control level of the lighting fixture 3 corresponding to the patterns P1 to P4 and the scene is configured to be managed by the master unit 1 as a light control scene setting table, the light control scene setting table can be easily managed and changed.

  Note that any transmission method among the above-described parent device 1, child device 2, and lighting fixture 3 can be adopted. For example, as a centralized control method, parent device 1 circulates child device 2 In addition to the operation of receiving the operation of the switch SW2 from the slave unit 2 of the designated address by accessing it and giving the dimming level instruction to the luminaire 3 using the zone address, as a distributed control method, The slave unit 2 and the slave unit 2 are treated equally as communication nodes, the slave unit 2 transmits the operation information of the switch SW2 by designating the source address and the destination address to the master unit 1, and the master unit 1 may be an operation of designating a zone address to the lighting device 3 and giving an instruction of a light control level. In any case, since only the transmission destination address (zone address) needs to be designated from the master unit 1 to the lighting fixture 3, the transmission source address is not necessary, and the lighting fixture 3 is controlled by the zone address. Therefore, the lighting device 3 does not require an individual address, and even if a plurality of lighting devices 3 are included in each of the zones Z11, Z12, Z21, Z22, Z31, and Z32, the zones Z11 and Z12 are transmitted. , Z21, Z22, Z31, and Z32, it is possible to give a desired dimming level to the lighting fixture 3 only by transmitting the dimming level once. That is, the traffic of the signal line 4 can be significantly reduced as compared with the case where the dimming level is individually transmitted to each lighting fixture 3.

  In the above-described embodiment, an example in which a room is divided into three areas A1 to A3 has been described, but it goes without saying that the number of areas is not particularly limited.

(Embodiment 2)
In the first embodiment, the patterns P1 to P4 are selected using the operation unit 11 provided in the base unit 1, but in the present embodiment, the patterns P1 to P4 are automatically selected according to the position of the partition 5. It is. The partition 5 used in the present embodiment is a partition wall, and the installation position in the room is determined. Further, an installation member is attached to a place where the partition 5 is installed in the room, and the room can be divided by mounting the partition 5 defined on the installation member. Below, the partition 5 and the member for installation are called an area division member. The area dividing member includes a rail provided in the room for moving the partition 5.

  In this embodiment, the partition child device 6 having the configuration shown in FIG. 3 is provided in the area dividing member, and the partition child device 6 notifies the parent device 1 whether or not the partition 5 is installed at a fixed position. is there. The partition slave unit 6 includes a position detection unit 61 that detects whether or not the partition 5 is mounted at a fixed position, and a transmission unit 62 that notifies the base unit 1 of a detection result by the position detection unit 61. The detection result of the position detection unit 61 is given to the transmission unit 62 through the control unit 60 whose main component is a microcomputer. The control unit 60 determines whether the detection result of the position detection unit 61 is correct. It has a function of controlling the transmission timing of the transmission unit 62 so that the detection result is reliably transmitted to the parent device 1 through the transmission unit 62. Further, the partition slave unit 6 is provided with a power supply unit 63 for supplying power to the internal circuit. The power supply unit 63 can employ a configuration that generates power for the internal circuit from an AC power supply such as a commercial power supply, or a configuration that generates power for the internal circuit from a battery. Since the position detector 61 only needs to detect whether or not the partition 5 is mounted at a fixed position, a switch that detects the presence or absence of the partition 5 is used as the position detector 61. That is, a switch that can detect whether or not the partition 5 is mounted is disposed at a portion where the partition 5 is shown in FIG. The transmitting unit 62 may be configured to communicate with the parent device 1 wirelessly using infrared rays or radio waves as a transmission medium, in addition to a configuration that connects to the signal line 4 and communicates with the parent device 1 by wire.

  It is assumed that the same dimming scene setting table as that of the first embodiment is registered in the master unit 1, and the pattern P1 that makes the entire room one space without using the partition 5 and the two partitions 5 are used. A pattern P2 that divides the room into three areas A1 to A3, a pattern P3 that divides the room into two using only the right partition 5 in FIG. 2, and a room that uses only the left partition 5 in FIG. It is assumed that the pattern P4 to be divided can be selected. As described above, the partition slave unit 6 is provided in each area dividing member corresponding to each partition 5, and each partition slave unit 6 is set with a unique address in the same manner as the slave unit 2. Therefore, the master unit 1 can know from the notification from the partition slave unit 6 whether or not the two partition units 5 are respectively mounted at the fixed positions. That is, the master unit 1 receives the notification of the detection result in the position detection unit 61 from the two partition slave units 6 and combines the detection results of the two, so that the two partitions 5 are not mounted at the fixed position. The master unit 1 can know a total of four states: a state where both of the two partitions 5 are mounted at a fixed position and two states where only one of the partition 5 is mounted at a fixed position. become.

  Since the four states described above correspond to the patterns P1 to P4, respectively, the master unit 1 can automatically select the patterns P1 to P4 according to the notification content from the partition slave unit 6. For example, when the partition 5 is not used and the pattern P1 is selected, the partition slave unit 6 notifies the master unit 1 that the partition 5 on the left side of FIG. In the master unit 1, the pattern P4 is selected when there is no notification of the installation of the partition 5 from the partition slave unit 6 corresponding to the right partition 5. In addition, in a state where the pattern P4 is selected, when the parent machine 1 is notified of the attachment of the partition 5 from the partition child device 6 corresponding to the right partition 5, the parent machine 1 selects the pattern P2. In addition, in a state where the pattern P2 is selected, when a notification that the partition 5 is removed from the partition slave unit 6 corresponding to the left partition 5, the master unit 1 selects the pattern P3. As described above, the base unit 1 automatically selects the patterns P1 to P4 corresponding to the position of the partition 5 by notifying the mounting state of the partition 5 from the partition slave unit 6.

  That is, when the room is divided by the partition 5, the patterns P1 to P4 are automatically selected without operating the master unit 1, so that the user does not perform the setting operation for the patterns P1 to P4. -P4 is selected, and convenience is improved. Other configurations and functions are the same as those of the first embodiment.

(Embodiment 3)
In the second embodiment, a configuration is adopted in which the partition unit 6 is provided in the area dividing member to notify the parent unit 1 of the presence or absence of the partition 5, but the distance from the partition 5 to the parent unit 1 is measured. Whether or not the partition 5 is attached using the measurement result of the distance measurement sensor by adding a distance measurement sensor or notifying the measurement result of the distance measurement sensor provided separately from the parent device 1 to the parent device 1 May be detected.

  FIG. 4 shows an example in which the distance measuring sensors 7a and 7b for measuring the distance to each partition 5 are provided in the main unit 1, and the presence or absence of two partitions 5 is detected by the distance measuring sensors 7a and 7b. Therefore, the base unit 1 is installed in the area A2. That is, each distance measuring sensor 7a, 7b measures the distance from the position where the master unit 1 is installed to each corresponding partition 5, and the master unit 1 defines the distance measured by each distance measuring sensor 7a, 7b. If it is within the range, it is determined that the partition 5 associated with each distance measuring sensor 7a, 7b is attached at a fixed position, and if it is out of the range, it is determined that the partition 5 is removed. For example, in the example shown in FIG. 4A, the distance measured by both distance measuring sensors 7a and 7b is within a specified range. Therefore, it is determined that both partitions 5 are mounted in the base unit 1, and the pattern P1 Select. In the example shown in FIG. 4B, the distance measured by the distance measuring sensor 7a is within the specified range, but the distance measured by the distance measuring sensor 7b is out of the range. It is determined that the partition 5 is attached and the right partition 5 is removed, and the pattern P4 is selected. Other configurations and functions are the same as those of the second embodiment. In this embodiment, since the maximum of two partitions 5 are used, the two distance measuring sensors 7a and 7b are arranged in the central area A2, but the number of distance measuring sensors is (number of partitions 5 minus one). Needless to say, the number and arrangement of distance measuring sensors are determined according to the maximum number of partitions 5 that can be installed in the room.

(Embodiment 4)
In each embodiment mentioned above, although each area A1-A3 and each zone Z11, Z12, Z21, Z22, Z31, Z32 were shown as an example fixed, this embodiment is in the position of the partition 5. A configuration is adopted in which the zone is automatically set in response. As in the second embodiment, the position where the partition 5 can be installed is defined in the room, and the position detection unit 61 of the partition slave unit 6 is provided at the position where the partition 5 can be installed.

  In this embodiment, as shown in FIG. 5, the partition 5 can be installed in five positions E1 to E5 in the room, and six areas A1 to A6 are formed in the room. Here, similarly to the above-described embodiment, if two or more zones are formed in each of the areas A1 to A6, twelve or more zones are formed. The number of patterns, which is the number of combinations of the positions of the partitions 5, is 32. It takes time to set many such patterns in the dimming scene setting table, and even if all patterns are set, it is considered that patterns that are not actually used are included. In addition, since the plurality of areas A1 to A6 are used as one space depending on the position of the partition 5, each zone may be set in a range used as one space in such a case. If each of the areas A1 to A6 is divided into a plurality of zones, the number of data in the dimming scene setting table increases. Therefore, in this embodiment, when the partition 5 is actually installed, a dimming scene setting table is created only for the pattern, and the zone is automatically set in a range that is used as one space via the partition 5. This makes it easy to create a dimming scene setting table.

  In order to realize the above-described function, each lighting device 3 is set with an individual address, and the storage unit 13 of the base unit 1 stores the individual address of the lighting device 3 and the position of the lighting device 3. The associated table is registered in advance. The individual address of the luminaire 4 is the portion of “n” of the reference numeral “ADD: n” in FIG. In the illustrated example, since the luminaires 3 are arranged in a matrix in the room, the row number x and the column number y are combined to represent the position of the luminaire 3 in the form of “xy”. Accordingly, in the illustrated example, the position of “ADD: 1” is “1-1”, the position of “ADD: 2” is “2-1”, and the position of “ADD: 5” is “1-2”. "become. In addition, the individual address of the lighting fixture 3 should just be matched with the position, and does not need to be arranged in order like FIG.

In the present embodiment, when the partition 5 is installed at a desired position, the base unit 1 is notified of the installation position of the partition 5, and the base unit 1 automatically sets a zone under an appropriate condition according to the installation position of the partition 5. . The conditions for forming the zone can be defined as follows, for example.
1. One space divided through the partition 5 is composed of two or four zones.
2.1 zones are composed of two or more lighting fixtures 3 each having a continuous address.
3. When three or more lighting fixtures 3 are included in one zone, different zones are not set in the same row (for example, “ADD: 1” and “ADD: 3” in FIG. 5 are not included in the same zone). ).
The conditions described above are examples, and the conditions for forming the zone may be set as appropriate. Further, such conditions may be incorporated into the parent device 1 to obtain a product, but conditions according to the site may be set in the parent device 1.

  Thus, the zone setting operation is performed according to the following procedure. That is, when the partition 5 is arranged at a desired position (for example, position E1), the base unit 1 is notified that the partition 5 is installed from the position detection unit 61 at the position. Base unit 1 determines a zone for each space divided by partition 5 by applying appropriate conditions as described above. When the partition 5 is installed at the position E1, the area A1 includes four luminaires 3. Therefore, the two luminaires 3 at the positions "1-1" and "1-2" and the position "1" -3 ”and“ 1-4 ”two lighting fixtures 3 each form a zone. In addition, four zones are formed by the lighting fixtures 3 included in the areas A2 to A6. For example, each of the areas A2, A3, and A4 forms one zone, and the areas A5 and A6 are collectively formed to form one zone.

  After the base unit 1 allocates the lighting fixtures 3 to be included in each zone as described above, the base unit 1 transmits a zone address to each lighting fixture 3. That is, since the lighting device 3 to be included in each zone is determined in the base unit 1, the zone address is transmitted to each lighting device 3 in units of the lighting device 3 included in each zone, and the zone address is stored in each lighting device 3. Let After the zone addresses are stored in the respective lighting fixtures 3 in this way, if the dimming scene setting table is created in the master unit 1, the lighting fixtures 3 are adjusted in units of zones in the same manner as in the first embodiment. It becomes possible to control the light level. The dimming scene setting table set in this way is equivalent to one type of pattern in the first embodiment. Such a dimming scene setting table can store a plurality of sets in the master unit 1. Moreover, since each area A1 to A6 is not divided into two zones as in the first embodiment, but is set according to the position of the partition 5, the zones included in each dimming scene setting table Is reduced. In this way, the room can be freely divided by the partition 5 as well as the zones constituting each divided space are automatically set, so that it is not necessary to create a dimming scene setting table. It can save a lot of labor. Further, if the number of dimming scene setting tables is the number of combinations that are assumed to actually install the partitions 5, the dimming scene setting table can be created even if the number of available partitions 5 is relatively large. It becomes relatively easy. Other configurations and operations are the same as those of the first embodiment. In addition, after setting the dimming scene setting table to the master unit 1, the dimming scene setting table (pattern) may be automatically selected by installing the partition 3 as in the second embodiment.

  In the above-described example, only one partition 5 is used, but even when two or more partitions 5 are used, the zone can be divided into zones by appropriately setting conditions. Can be set automatically.

(Embodiment 5)
In the configuration of the fourth embodiment, the position detection unit 61 is provided at predetermined positions E1 to E5 in order to detect the position of the partition 5. However, in the present embodiment, a distance measuring sensor is provided as in the third embodiment. Thus, the position of the partition 5 is detected. Here, in order to simplify the description, a case will be described in which a room is divided into left and right by a single partition 5 slidably moving on rails arranged along the left and right direction in FIG. In this case, there is only one distance measuring sensor 7 because there is only one partition 5. The distance measuring sensor 7 obtains the position of the partition 5 from the reference position E0 by measuring the distance to the partition 5. Further, the base unit 1 includes a length L1 of the lighting fixture 3 in the left-right direction in FIG. 6 and an arrangement interval L2 of the lighting fixture 3 (a distance from the reference position E0 to one end of the lighting fixture 3, and a pair adjacent in the left-right direction). The distance between each end of the luminaire 3 is assumed to be equal).

  In the present embodiment, when the user moves the partition 5 to a desired position, the distance to the partition 5 is measured by the distance measuring sensor 7 (although the trigger for measurement may be given by the master unit 1). The measurement may be repeated at predetermined time intervals). If the distance from the distance measuring sensor 7 to the partition 5 is known, the base unit 1 is a position where the partition 5 overlaps the lighting fixture 3 or is positioned between a pair of adjacent lighting fixtures 3 by calculating the distance. You can recognize whether you are doing. Therefore, if the partition 5 is located between a pair of adjacent lighting fixtures 3, the zone can be automatically set by replacing the position with the positions E1 to E5 of the fourth embodiment. However, in the configuration of this embodiment, the partition 5 is not selected and installed from the specified position, but the partition 5 can be arranged at an arbitrary position in the left-right direction in FIG. The partition 5 may overlap. Therefore, it is possible to set whether the lighting fixture 3 is turned on or off when the partition 5 overlaps the position of the lighting fixture 3, and whether the lighting fixture 3 is included in the left or right space with respect to the partition 5 in the case of lighting. Keep it as Such setting can be performed in the master unit 1 or the partition slave unit 6.

  When setting is possible in the partition slave unit 6, the lighting unit 3 is selected to be turned on or off by an operation unit (not shown) provided in the partition slave unit 6 and measured by the distance measuring sensor 7. In addition to the selected distance, the selected information is also transmitted to the base unit 1 together. In the base unit 1, based on the received information, if the lighting device 3 belonging to the position of the partition 5 is “off”, the lighting device 3 is not included in the zone, and if it is “on”. These luminaires 3 belong to one of the two spaces divided by the partition 5 and the zones are automatically set in the same manner as in the fourth embodiment.

  On the other hand, when the lighting device 3 that overlaps the partition 5 can be turned on and off in the base unit 1, the illumination that overlaps the partition 5 using the liquid crystal display DP and the switch SW1 provided in the operation unit 21 is enabled. Whether the fixture 3 is turned on or off is selected in advance, and when the measurement result of the distance from the distance measuring sensor 7 to the partition 5 is received, whether or not the partition 5 overlaps the lighting fixture 3 is determined. If they overlap, the zone is automatically determined according to the selected condition. Other configurations and operations are the same as those of the fourth embodiment.

(Embodiment 6)
In each embodiment described above, when the room is divided into a plurality of spaces using the partition 5, the dimming level that can be selected by each slave unit 2 is changed according to the position of the partition 5. In the embodiment, the dimming level of the luminaire 3 is changed based on information detected by a sensor provided at an appropriate place in the illumination space without using a partition. Therefore, the illumination space that is the target of the present embodiment is not limited to a room, and can be applied to an illumination space that shares one floor.

  In the present embodiment, as shown in FIG. 7, sensors 8 are arranged in the respective areas A1 to A3. Each sensor 8 is connected to the signal line 4 and has a function of transmitting detected information to the base unit 1. That is, an address is set for each sensor 8 in the same manner as the lighting fixture 3. The master unit 1 includes a fader, and the dimming level of the lighting fixture 3 can be adjusted by using the fader.

  The sensor 8 is assumed to be at least one of a human sensor and a brightness sensor. As shown in FIG. 8, the detection unit 81 that performs sensing and the detection result of the detection unit 81 connected to the signal line 4 are displayed. And a communication unit 82 for notifying the base unit 1. If the sensor 8 is a human sensor, the detection unit 81 detects the presence or absence of a person in each of the areas A1 to A3 where the sensor 8 is provided. If the sensor 8 is a brightness sensor, the detection unit 81 The brightness of the installation position of the sensor 8 (part representing each area A1 to A3) is detected. In the illustrated example, each of the areas A1 to A3 is composed of two zones Z11, Z12, Z21, Z22, Z31, and Z32, and the sensor 8 corresponds to the slave unit 2 of the first embodiment. Therefore, the areas A1 to A3 are used as units. An address is set. Hereinafter, the address of the sensor 8 is referred to as a sensor address.

  Similarly to the first embodiment, the lighting device 3 is set with zone addresses in units of zones Z11, Z12, Z21, Z22, Z31, and Z32. In addition, as shown in Table 2, for example, the sensor address of each sensor 8 is the zone address of two zones Z11, Z12, Z21, Z22, Z31, and Z32 that form areas A1 to A3 in which the sensor 8 is arranged. And the dimming level to be given to the luminaire 3 in each of the zones Z11, Z12, Z21, Z22, Z31, and Z32. That is, in the present embodiment, the dimming scene setting table of the base unit 1 has the contents shown in Table 2. Table 2 shows the case where the sensor 8 is a human sensor, and shows the dimming level of each zone Z11, Z12, Z21, Z22, Z31, Z32 when each sensor 8 detects the presence of a person. When the sensor 8 is a brightness sensor, by setting a threshold value, the dimming level is set according to the magnitude of the detection value of the sensor 8 and the threshold value, or the detected brightness is set in a plurality of sections. The dimming level is set for each section.

  Since the dimming level is given from the master unit 1 to the lighting fixture 3 using the zone address in the same manner as in the first embodiment, the transmission source address from the master unit 1 to the lighting fixture 3 is not required. For example, as shown in FIG. 9, it is only necessary to include destination address data AD and dimming level data (LV) between the start bit ST and the stop bit SP.

  Here, the operation will be described by taking as an example a case where the presence of a person is detected by the sensor 8 (shown as a sensor (area A1) in Table 2) arranged in the area A1. In this case, since the detection of a person is notified to the master unit 1 from the sensor 8 whose sensor address corresponds to the area A1, the master unit 1 refers to the dimming scene setting table as shown in Table 2. It is extracted that a dimming level of 100% is given to each of the two zones Z11 and Z12. According to the extracted information, the base unit 1 accesses the luminaires 3 of the zones Z11 and Z12 using the zone address, and gives a dimming level of 100% for each of the zones Z11 and Z12. The same applies when the detection of a person is notified from the sensors 8 arranged in the areas A2 and A3. By referring to the dimming scene setting table, the zones Z11, Z12, Z21, and Z22 to which the dimming level should be transmitted are described. , Z31, Z32 and the dimming level to be given are determined. In the present embodiment, when a person is detected by the sensor 8, a dimming level is given only to the lighting fixtures 3 in the zones Z11, Z12, Z21, Z22, Z31, and Z32 where the sensor 8 is disposed. However, by appropriately setting the dimming scene setting table, it is possible to give dimming levels to the lighting fixtures 3 in the other zones Z11, Z12, Z21, Z22, Z31, and Z32.

  In the configuration of the present embodiment, as in the first embodiment, the dimming level is given from the parent device 1 using the zone address set in the lighting device 3, so that the transmission signal transmitted from the parent device 1 to the lighting device 3 is It is not necessary to include the information of the transmission source, and the dimming level can be simultaneously given to the plurality of lighting fixtures 3 by one access, and the operation of the lighting fixture 3 is associated with the detection result of the sensor 8. Since the dimming scene setting table provided in the master unit 1 performs, the desired lighting fixture 3 is linked to the detection of the sensor 8 without setting the lighting control level individually for each lighting fixture 3 in advance. It becomes possible to light at the dimming level. In the present embodiment, when the slave unit 2 is provided, the address of the slave unit 2 is set separately from the address of the sensor 8, and the operation of the switch SW 2 in the slave unit 2 and the information detected by the sensor 8 are set. It is necessary to prescribe the combination method in the base unit 1. Further, in the present embodiment, two zones Z11, Z12, Z21, Z22, Z31, and Z32 are set in each of the areas A1 to A3. However, a setting method for the zones Z11, Z12, Z21, Z22, Z31, and Z32 is set. Is the same as that of Embodiment 1, and is not limited to this embodiment. Other configurations and operations are the same as those of the first embodiment.

(Embodiment 7)
In the present embodiment, similarly to the sixth embodiment, the dimming level to be given to the lighting fixture 3 is determined based on the output of the sensor 8, and a human sensor is used as the sensor 8. Therefore, FIG. 7 is also referred to in this embodiment. Assuming that a person moves, there are cases where the dimming level of each lighting fixture 3 is desired to be changed and where it is not desired to be changed as the person moves. Therefore, in the present embodiment, in each sensor 8 as a human sensor provided with a detection unit 81 that detects the presence / absence of a person, the master unit 1 is turned off when the presence of a person is detected. Instead of notifying immediately, a timer is provided for notifying the master unit 1 after a predetermined time has elapsed since it was detected that a person was absent.

  In the present embodiment, it is assumed that a dimming scene setting table having the contents shown in Table 3 is set in the parent device 1. In the example of Table 3, when one of the sensors 8 provided in the areas A1 and A2 is detected, the lighting fixtures in the zones Z11 and Z12 are turned on at 100%, and the lighting fixtures 3 in the zones Z21 and Z22 are turned on. Lights at 70%. When a person is detected by the sensor 8 provided in the area A3, the lighting fixture 3 in the zone Z31 is turned on at 70%, and the lighting fixture 3 in the zone Z32 is turned on at 100%. In this example, even if the time limit of the timer built in the sensor 8 expires when a person moves from the area A1 to the area A2 or from the area A2 to the area A1, the light output of the lighting fixture 3 is increased. No change will occur. For example, assuming that a person has moved from area A1 to area A2, even if the time limit of the timer has elapsed since the person 8 is no longer detected by the sensor 8 present in area A1, the sensor 8 provided in area A2 Since a person is detected, the light output of the lighting fixture 3 is not changed by referring to the dimming scene setting table as shown in Table 3. In other words, if the dimming levels of the zones Z11, Z12, Z21, and Z22 are set to be equal as shown in Table 3 with respect to the areas A1 and A2, the sensors 8 in both the areas A1 and A2 are equivalent, The same control as when connected in parallel is possible.

  On the other hand, if no person is detected in the sensors 8 in the other areas A2 and A3 when the time limit of the timer elapses after the sensor 8 existing in the area A1 is no longer detected, the lighting apparatus in Table 3 Since there is no combination instructing lighting of 3, all the lighting fixtures 3 are turned off in the base unit 1. In the example shown in FIG. 7, one sensor 8 is arranged in one area A1 to A3, but a plurality of sensors 8 can be arranged in one area A1 to A3. In this case, in a state in which none of the plurality of sensors 8 provided in each of the areas A1 to A3 detects a person (after the timed operation ends when the timer operates in a timed manner), people in the areas A1 to A3 Is no longer present.

  In the configuration of the present embodiment, the sensors 8 existing in the plurality of areas A1 to A3 can be handled equivalently, and both areas A1 to A1 are based on the detection results of the sensors 8 existing in the two areas A1 to A3. It is possible to control the dimming level of the luminaire 3 as if both sensors 8 are connected in parallel without changing the dimming level of the luminaire 3 of A3. As a result, for example, after the lighting device 3 in the areas A1 and A2 is turned on when the sensor 8 existing in the area A1 detects a person, the person from the area A1 (the human detection range by the sensor 8 in the area A1) When the person moves and the person is detected by the sensor 8 provided in the area A2, it is possible to avoid the inconvenience that the lighting fixture 3 is turned off even though the person still remains in the area A1. Further, since the detection results of the sensor 8 are combined in the master unit 1, the lighting fixture 3 only receives the dimming level from the master unit 1, and the lighting fixture 3 does not require judgment on the detection result of the sensor 8. Therefore, a configuration for interlocking the lighting state of the illumination load 3 with the detection result of the sensor 8 can be realized easily and inexpensively. Other configurations and operations are the same as those in the sixth embodiment.

(Embodiment 8)
As shown in FIG. 10, the present embodiment has two areas A1 and A2, four zones Z11 to Z14 are provided in the area A1, and two zones Z21 and Z22 are provided in the area A2. . In addition, two slave units 2 are arranged in the area A1. Each slave unit 2 includes an operation unit 21 that can instruct the dimming level of the luminaire 3 as with the fader provided in the master unit 1. Here, it is assumed that the operation unit 21 includes an up switch that increases the dimming level and a down switch that decreases the dimming level. The up switch and the down switch have a function of increasing / decreasing the dimming level by one specified step by one pressing operation, and continuously increasing / decreasing the dimming level when the pressing operation is continued beyond the specified time.

  The present embodiment includes a sensor 8 as in the sixth and seventh embodiments. In the illustrated example, the sensors 8 are disposed in the zones Z12, Z22, and Z32, the sensor 8 disposed in the zone Z12 is a brightness sensor, and the sensors disposed in the zones Z22 and Z32 are human sensors. . That is, the brightness sensor and the human sensor are arranged in the area A1. The brightness sensor detects the illuminance on the floor surface or the desk surface, is installed on the ceiling, and monitors the illuminance below vertically. This embodiment has a function of controlling the light control level of the lighting fixture 3 so as to keep the illuminance detected by the brightness sensor constant. Here, the light control level is controlled by the brightness sensor for the lighting fixtures 3 in the zones Z11 and Z12, and the lighting fixture 3 in the zones Z21, Z22, Z31, and Z32 is controlled by the human sensor.

  In the master unit 1, the contents shown in Table 4 are set as a dimming scene setting table. As can be seen from a comparison of Table 4 with Table 2, “interlocking prohibited” is designated for the lighting fixtures 3 in the zones Z11 and Z12 to be controlled by the brightness sensor, and the human sensor controls the control. A dimming level is set for each of the lighting fixtures 3 in the target zones Z21, Z22, Z31, and Z32. For the lighting fixtures 3 in the zones Z11 and Z12 for which “interlocking prohibition” is designated, transmission of the dimming level from the parent device 1 to the lighting fixture 3 is prohibited. When setting the contents of the dimming scene setting table, if a brightness sensor is registered as the sensor 8 and zones Z11 and Z12 associated with the brightness sensor are input, the zones Z11 and Z12 are adjusted. Light level input is prohibited.

  The brightness sensor directly transmits a detection value to the lighting fixtures 3 in the zones Z11 and Z12, which are objects to be controlled by the brightness sensor, without using the master unit 1, and controls the dimming level of the lighting fixture 3. In other words, the zone addresses of the zones Z11 and Z12 to be controlled are registered in the brightness sensor, and the detected values are transmitted to the signal line 4 by specifying the zone addresses. In addition, a target value of illuminance is set in the brightness sensor, and the dimming level for the lighting fixture 3 is instructed so that the detected value is maintained at the target value.

  When the zone address is set from the master unit 1 to the lighting fixture 3 and the sensor 8, the master unit has a function that allows the lighting fixture 3 to set the same zone address as the zone address set to the brightness sensor. When the zone address is set, the brightness sensor and the brightness sensor set the same zone address to the lighting fixture 3 to be controlled. By making such an association between the brightness sensor and the luminaire 3, it is possible to directly transmit the dimming level from the brightness sensor to the luminaire 3 without using the master unit 1. The control based on the human sensor is the same as in the sixth embodiment or the seventh embodiment.

  In the configuration of the present embodiment, “interlocking prohibition” can be set in the dimming scene setting table provided in the base unit 1, and the master unit 1 is set for the zones Z11 and Z12 in which “interlocking prohibition” is set. In FIG. 5, the setting of the dimming level is prohibited for the dimming scene setting table, and the transmission of the dimming level from the master unit 1 to the lighting fixture 3 is also prohibited. On the other hand, the same zone address is set for the brightness sensor and the lighting fixture 3 that is the control target of the brightness sensor, and the dimming level is directly transmitted from the brightness sensor to the lighting fixture 3. With such an operation, when controlling the dimming level of the luminaire 3 in conjunction with the sensor 8, compared with the case where the detection information of all the sensors 8 is notified to the parent device 1, the parent device 1 The signal processing load of the master unit 1 can be reduced and the traffic of the signal line 4 can be reduced. In particular, when transmitting continuously like the detection value of the brightness sensor, The effect of reducing traffic on the signal line 4 is increased. Other configurations and operations are the same as those in the sixth embodiment.

(Embodiment 9)
The present embodiment is a technique for facilitating confirmation of a zone address set in a specific lighting fixture 3, and in order to acquire a zone address of the lighting fixture 3 belonging to a specific zone Z1 to Z6, A remote control device 9 capable of wireless (infrared or radio wave) data communication with the base unit 1 is used. The remote control device 9 has a function of switching the operation mode of the parent device 1 and a function of receiving a zone address from the parent device 1.

  As shown in FIG. 11, the remote control device 9 includes a control unit 90 using a microcomputer, and performs processing corresponding to the operation of the operation unit 91 including a switch. A communication unit 92 is connected to the control unit 90, and the communication unit 92 performs bidirectional data communication using infrared or radio waves as a medium. In addition, a display unit 93 such as a liquid crystal display is connected to the control unit 90 as necessary. When the display unit 93 is provided, the received content received by the communication unit 92 is displayed. Moreover, it may replace with the display part 93 and the buzzer which alert | reports reception may be provided. Power is supplied to the internal circuit of the remote control device 9 from a power supply unit 94 having a battery.

  In this embodiment, as shown in FIG. 12, each lighting device 3 is set with an individual address (the individual address of the lighting device 3 is shown in the form of “ADD: n”), and Assume that different zone addresses are set for the respective lighting fixtures 3 and the respective sensors 8. The individual address and the zone address are stored in a storage unit including a nonvolatile memory provided in the lighting fixture 3 and the sensor 8. A human sensor is used as the sensor 8. In the example shown in FIG. 12, 24 lighting fixtures 3 are arranged, and one sensor 8 is arranged for every four lighting fixtures 3. In other words, the lighting fixtures 3 are arranged in a matrix so as to be in 4 rows and 6 columns, and one zone Z1 to Z6 is formed by the lighting fixtures 3 in 2 rows and 2 columns, and a sensor is formed in the center of each zone Z1 to Z6. 8 is arranged.

  The procedure for acquiring the zone address of each lighting fixture 3 using the remote control device 9 will be described below. In order to perform this work, first, the base unit 1 is shifted to the specific information acquisition mode by operating the remote control device 9. When the remote control device 9 instructs the parent device 1 to switch to the specific information acquisition mode, the remote control device 9 shifts to a reception standby state after a predetermined time.

  On the other hand, the base unit 1 instructed to shift to the specific information acquisition mode from the remote control device 9 transmits a specific information acquisition mode command to all the lighting fixtures 3 and the sensors 8. When receiving the specific information acquisition mode command, the lighting fixture 3 and the sensor 8 maintain the control state at that time without changing. However, as will be described later, the luminaire 3 and the sensor that have received the command of the specific information acquisition mode so that the user carrying the remote control device 9 does not shift to the specific information acquisition mode until the user reaches the vicinity of the desired sensor 8. In 8, the mode transition is performed after a certain time.

  When the user carrying the remote control device 9 moves to the vicinity of the desired sensor 8 (in the zones Z1 to Z6 including the sensor 8) and performs an operation such as waving his hand, the presence of a person is detected in the sensor 8. (Here, it is assumed that a differential detection unit 81 such as a pyroelectric infrared sensor is provided). When the sensor 8 detects a person in the specific information acquisition mode, the sensor 8 notifies the base unit 1 of the person detection together with the zone address. Since the base unit 1 stores in advance the correspondence between the zone addresses of the lighting fixture 3 and the sensor 9 and the zones Z1 to Z6, when the zone address is notified from the sensor 8, it corresponds to any zone Z1 to Z6. Read what to do. In addition, if the zones Z1 to Z6 are known, the unique addresses and zone addresses of the lighting fixtures 3 belonging to the zones Z1 to Z6 can be acquired from the stored contents of the master unit 1.

  When the zones Z1 to Z6 are specified in the master unit 1, the master unit 1 transmits a command for canceling the specific information acquisition mode to each lighting device 3 and the sensor 8. That is, the luminaire 3 and the sensor 8 can perform normal operations. As described above, the specific information acquisition mode is immediately canceled after acquiring the zones Z1 to Z6 in the base unit 1 when the specific information acquisition mode is continued for a long time. This is because the process in the base unit 1 becomes complicated.

  After canceling the specific information acquisition mode, base unit 1 notifies remote control device 9 that zones Z1-Z6 of sensor 8 have been received. When the remote control device 9 receives the notification from the parent device 1, the remote control device 9 returns from a reception standby state to a state in which transmission is possible. Here, the zones Z1 to Z6 acquired by the master unit 1 and the individual addresses and zone addresses of the lighting fixture 3 may be displayed on the master unit 1, but the zones Z1 to Z6 and If the unique address and the zone address of the lighting fixture 3 are transferred to display the zones Z1 to Z6 and the unique address and zone address of the lighting fixture 3 on the remote control device 9, the convenience is enhanced.

  In the above-described example, the remote control device 9 is switched between a transmittable state and a reception standby state. However, the remote control device 9 can perform transmission and reception separately. It is not always necessary to switch the state. Of course, malfunction may occur due to reception of noise in the reception standby state, so that the possibility of receiving unnecessary information can be reduced by limiting the reception standby period.

  By adopting the above-described configuration, the zones Z1 to Z6 to which the sensor 8 belongs and the unique address and zone address of the lighting fixture 3 can be easily obtained, and convenience is enhanced. That is, in general, if a unique address or zone address set for the lighting fixture 3 and the sensor 8 is to be acquired, an operation of copying the information on paper or the like when setting these pieces of information is necessary. By adopting the configuration, necessary information can be acquired when necessary using the remote control device 9, so that the copying operation becomes unnecessary. In addition, since the individual address, the zone address, and the zone address of the sensor 8 acquired by operating the remote control device 9 are associated with the position of the person, the position information is registered in the base unit 1 or the like. This makes it easy to set data in the master unit 1. Further, since the information acquired in the master unit 1 or the remote control device 9 is displayed, it is not necessary to display the information on the lighting fixture 3 or the sensor 8, and an increase in cost is caused by providing a display member on the lighting fixture 3 or the sensor 8. Absent.

  If a brightness sensor is used in place of the human sensor and the brightness sensor is specified by irradiating the light sensor with a light beam, the brightness sensor can be used in the same manner as the human sensor. Is possible. Moreover, although the above-mentioned example illustrated the case where the zone address of the lighting fixture 3 and the zone address of the sensor 8 differ, when both are the same, the zone address of the sensor 8 is the zone address of the light fixture 3. Therefore, the operation of registering the zone address of the sensor 8 in association with the zones Z1 to Z6 in the base unit 1 becomes unnecessary. Other configurations and operations are the same as those of the other embodiments.

(Embodiment 10)
In the ninth embodiment, since the remote control device 9 performs wireless data communication with the parent device 1, the distance between the remote control device 9 and the parent device 1 may be increased, which can be realized at low cost. Data communication may be difficult when infrared is used as a transmission medium. Therefore, in the present embodiment, data communication using infrared rays is possible from the lighting fixture 3 to the remote control device 9. In addition, the lighting fixture 3 is provided with a terminal that is notified of detection of a person from the sensor 8 separately from a terminal connected to the signal line 4. The remote control device 9 is provided with a display function.

  As in the ninth embodiment, the remote control device 9 instructs the base unit 1 in the specific information acquisition mode, and the user carrying the remote control device 9 moves to the vicinity of the desired sensor 8 and is detected by the sensor 8. Then, the zone address of the sensor 8 is notified to the base unit 1. In this embodiment, when the sensor 8 detects a person, the detection of the person is also notified to the luminaires 3 arranged in the same zones Z1 to Z6 as the sensor 8 (see FIG. 12). Then, when the detection of the person is notified from the sensor 8, an individual address or zone address is notified to the remote control device 9 by radio. When the remote control device 9 receives information from the lighting fixture 3, the remote control device 9 returns to a transmittable state. Further, since the detection of the person is notified from the sensor 8 to the parent device 1, the specific information acquisition mode can be canceled in the parent device 1.

  By adopting such a configuration, the distance in which radio is used in the data communication path between the base unit 1 and the remote control device 9 is shortened, and infrared rays are transmitted in the remote control device 9 even in a relatively wide space. It can be used as a medium.

  In the present embodiment, the luminaire 3 can only transmit wirelessly to the remote controller 9, and the function of receiving a wireless instruction from the remote controller 9 and returning the zone address directly to the remote controller 9. Is not provided. This is because when a remote controller 9 gives an instruction to the luminaire 3 by infrared rays, a plurality of luminaires 3 may receive the instruction, and the position of the luminaire 3 that has received the instruction is specified. It is because it becomes impossible. On the other hand, in order to avoid such interference, it is conceivable to provide a receiving unit that receives an instruction from the remote control device 9 only in a specific lighting fixture 3, but considering the arrangement of each lighting fixture 3 when installing the lighting fixture 3. It becomes necessary to do, and construction work becomes troublesome. In addition, when radio waves are used as radio waves, transmission source and transmission destination IDs must be registered in advance according to the regulations of the Radio Law, and the registration work is troublesome if the number of lighting fixtures 3 increases. Furthermore, it is conceivable to use weak radio waves that do not require ID registration, but in this case, the same problem as in the case of using infrared rays occurs.

  In the present embodiment, when a person is detected by the sensor 8, a unique address or zone address is displayed on the remote control device 9 from the lighting fixtures 3 belonging to the same zone Z1 to Z6 as the sensor 8, so there is a possibility of interference. In addition, since infrared rays can be used as a transmission medium, it can be realized at a relatively low cost and labor during construction can be reduced. Other configurations and operations are the same as those of the ninth embodiment.

  In the present embodiment, the information acquired by the remote control device 9 can be displayed on the master unit 1 by transmitting it to the master unit 1 wirelessly after the work is completed. In this case, if only the zone address is transmitted from the remote control device 9 to the parent device 1, necessary information can be displayed on the parent device 1 by searching the data stored in the parent device 1 by the zone address. .

  In the ninth embodiment and the tenth embodiment, the technique for acquiring the zone address by the remote control device 9 has been described. However, the purpose of acquiring the zone address is to control the lighting fixtures 3 in the zones Z1 to Z6. At the same time as the release of the specific information acquisition mode, the control content such as turning on and off may be transmitted by designating the zone address, and the control content may be executed in the lighting fixtures 3 of the zones Z1 to Z6 designated by the zone address.

(Embodiment 11)
In each of the above-described embodiments, the case where only one parent device 1 is used has been shown. However, in this embodiment, a plurality of (two in the illustrated example) parent devices 1a and 1b are linked as shown in FIG. The case where it makes it explain is demonstrated. Below, the space which has arrange | positioned the lighting fixture 3 connected to each parent machine 1a, 1b via the signal wire | line 4 will be called floor Fa, Fb. The two floors Fa and Fb can be divided by a floor partition 51. The parent devices 1a and 1b are connected to each other via a communication line 41 provided separately from the signal line 4, and data communication can be performed with each other using individual IDs set for the respective parent devices 1a and 1b. Each of the floors Fa and Fb has three areas A1a to A3a and A1b to A3b, respectively, and the areas A1a to A3a and A1b to A3b can be divided by a partition 5. Since both the partition 5 and the floor partition 51 are movable and the floor partition 51 is installed, the master units 1a and 1b control the lighting fixture 3 independently for each floor Fa and Fb. And control of the lighting fixture 3 for each floor Fa and Fb becomes the same as that of Embodiment 6. FIG. The storage unit 13 (see FIG. 1) provided in the base unit 1 is provided with a main area and a sub area. When the floors Fa and Fb are divided by the floor partition 51, only data in the main area is used. When the floor partition 51 is removed and the floors Fa and Fb are connected, the data of the sub area is used together.

  Since the operation in the case of using the floor partition 51 is the same as that in the sixth embodiment, a case will be described below in which the floor partition 51 is removed and both floors Fa and Fb are used as one space. In this case, first, the master unit 1a, 1b is notified that the floor partition 51 has been removed. The notification that the floor partition 51 has been removed can be performed by operating each of the master units 1a and 1b, but means for detecting the position of the floor partition 51 (the position detection unit described in the second and third embodiments). It is desirable to automate the notification using a distance sensor or the like. The parent machines 1a and 1b establish a link by exchanging individual IDs through the communication line 41.

  When the link is established, the areas A1a to A3a managed by the master units 1a and 1b among the data of the dimming scene setting table stored in the main area of the storage unit 13 in the master units 1a and 1b, Zones Z11a, Z12a, Z21a, Z22a, Z31a, Z32a, Z11b, Z12b, Z21b, Z22b, Z31b, and Z32b forming A1b to A3b, and whether or not a dimming level is set for each zone address Information is exchanged, and the information received from the other parent device 1a, 1b is stored in the sub area of the storage unit 13 as management information related to the other parent device 1a, 1b in each parent device 1a, 1b.

  For example, if the dimming scene setting tables as shown in Tables 5 and 6 are set in the main area of the storage unit 13 in each of the master units 1a and 1b, information transmitted from the master unit 1a to the master unit 1b The management information stored in the sub area of the base unit 1b is as shown in Table 7.

  As described above, each master unit 1a, 1b has information on whether or not a dimming level is set for each zone address in the dimming scene setting table of the other master unit 1a, 1b. It is possible to use information set in the other parent device 1a, 1b. That is, even if the lighting fixture 3 is not connected to the master units 1a and 1b through the signal line 4, it can be controlled through the other master units 1a and 1b.

  Now, a case where a dimming level is given to the luminaires 3 belonging to the zones Z11a and Z12a in the floor Fa managed by the parent machine 1a using the parent machine 1b will be described as an example. Management information transmitted from the parent device 1a is stored in the sub area of the storage unit 13 of the parent device 1b, and it is recognized that the lighting devices 3 in the zones Z11a and Z12a can be controlled by the parent device 1a. Therefore, the lighting fixtures 3 in the zones Z11a and Z12a can be selected as the control target. As described in the first embodiment, since the five types of scenes S1 to S5 can be selected for each of the zones Z11a and Z12a, the scene S1 can be selected for the zones Z11a and Z12a of the floor Fa in the master unit 1b. it can.

  When the master unit 1b selects the scene S1 for the zones Z11a and Z12a of the floor Fa, the master unit 1b (control unit 10 (see FIG. 1)) has the individual ID (M-ID) of the master unit 1a and the zones Z11a and Z12a. A message including the zone address (Z-ADD) and the selected scene type (SC) is generated, and a transmission signal in a format in which a start bit ST and a stop bit SP are added to the message as shown in FIG. Transmission is performed from the parent device 1b to the parent device 1a through the communication line 41. When the base unit 1a receives the transmission signal as shown in FIG. 14 transmitted from the base unit 1b, the base unit 1a recognizes that it is an instruction to the base unit 1a by the individual ID, and further, the zone address (Z-ADD) and the type of scene (SC) is used to extract the dimming level corresponding to the instruction content from the dimming scene setting table. The processing after extracting the dimming level from the dimming scene setting table is the same as the case where the master unit 1a is used alone. In the example shown in Table 5, the dimming levels are respectively obtained for the zones Z11a and Z12a. Is given as an instruction for 100%.

  As described above, when the master units 1a and 1b indicate the dimming level to the lighting fixtures 3 managed in the other dimming scene setting table, the master units 1a and 1b that have been operated first are used. Becomes the master, and the master units 1a and 1b receiving the instruction from the master become slaves, and the dimming levels of the lighting fixtures 3 arranged on the floors Fa and Fb are controlled.

  In the example described above, the case where there are two master units 1a and 1b is illustrated. However, even when three or more master units are provided, each master unit is similar to the case where two master units 1a and 1b are used. By holding the data setting state in each other's dimming scene setting table, it becomes possible to control all the lighting fixtures 3 from any master unit.

  By adopting the configuration of the present embodiment, even when the lighting fixtures 3 provided in one space are controlled by a plurality of master units, the lighting fixtures 3 under the control of each master unit are different from each other. The dimming level can be given by operating the master unit. For example, when there is a limit on the number of lighting fixtures 3 that can be managed in one master unit (for example, when it is limited by the impedance of the signal line 4 or when it is limited by the number of addresses that the master unit can manage) However, it is possible to control the number of lighting fixtures 3 exceeding the limit by using a plurality of master units. In addition, since each parent device can be a master or a slave, even though each parent device does not manage all the lighting fixtures 3, which parent device is in relation to all the lighting fixtures 3 in the space. The light control level can be given also by the operation. As a result, the storage capacity of the storage unit 10 (see FIG. 1) provided in each parent device can be provided at a relatively low cost while being flexible, depending on how the space in which the lighting fixtures 3 are arranged is partitioned. It becomes possible to respond. Other configurations and operations are the same as those in the sixth embodiment.

Embodiment 12
In each embodiment described above, it is possible to switch between lighting and extinguishing of the lighting fixture 3 and designation of the dimming level at the time of lighting, but in this embodiment, when the lighting fixture 3 is turned on and off, The light output is gradually increased or decreased with time. That is, fade-in and fade-out are possible. In this embodiment, as shown in FIG. 15, the lighting fixtures 3 are arranged in a matrix of 7 rows and 9 columns, and four zones Z1 to Z4 are formed by partitioning in the vertical direction of the figure. . That is, three zones Z1 to Z3 in which the lighting fixtures 3 in 2 rows and 9 columns are arranged and one zone Z4 in which the lighting fixtures 3 in 1 row and 9 columns are arranged are formed. Further, it is assumed that the base unit 1 and the handset 2 are connected to the signal line 4 one by one.

  The base unit 1 of the present embodiment has a function of storing fade data. The fade data is given as the rate of change of time or dimming level. When the master unit 1 gives the dimming level to each of the zones Z1 to Z4, when fade-in or fade-out is designated, the previous dimming is performed. The dimming level newly instructed by the time or rate of change of the fade data from the level is reached. An example of fade data is shown in Table 8. In Table 8, time and the rate of change are associated with each of the zones Z1 to Z4, but only one of the time and the rate of change is required. The time is expressed in seconds, and the change per second of the dimming level expressed in% is used as the unit.

  Now, assume that the time shown in Table 8 is used as the fade data, and when one scene is selected in the handset 2, as shown in FIG. 16A, the dimming level given to the zone Z1 is 30% to 70%. %. Since the fade data for the zone Z1 is 1 s, the dimming level of the zone Z1 is 30% when the dimming level is instructed to each of the zones Z1 to Z4 at time t0 as shown in FIG. 16B. Thus, the light control level is made to reach 70% at a constant change rate from time t0 to 1s. That is, since 1 s is required for the dimming level to change by 40%, the rate of change is 40% / s, and when the dimming level is indicated, the difference between the previous dimming level and the new dimming level is 40. When it is%, the case where the change rate is set to 40% / s is equivalent to the case where the time is set to 1 s. However, if the difference between the previous dimming level and the new dimming level is not 40% when the dimming level is instructed, the change in the light output between the case where the fade data is given by time and the rate of change is given. Needless to say, the rates are different. Similarly, the zones Z2 to Z4 reach the dimming levels given after 2s, 3s and 4s from time t0, respectively.

  On the other hand, when an instruction is given to change the dimming level from 70% to 30% for the zone Z1 at time t1, the dimming level reaches 30% after 1 s from time t1 in the zone Z1, and other zones In Z2 to Z4, the dimming levels given after 2s, 3s and 4s respectively are reached.

  By registering fade data in the master unit 1 as in the present embodiment, fade-in and fade-out in units of zones Z1 to Z4 can be performed. Other configurations and operations are the same as those of the other embodiments described above.

(Embodiment 13)
In the dimming scene setting table of the master unit 1 described in the first embodiment, when there are three areas A1 to A3, five types of scenes can be selected for each area A1 to A3. Up to 15 scenes are created. The master unit 1 and each slave unit 2 can be configured so that all 15 types of scenes can be selected, but the master unit 1 and each slave unit 2 are arranged in association with the areas A1 to A3. Therefore, in the configuration of the first embodiment, the scenes selected by the parent device 1 and each child device 2 are limited to the area A1 to A3. In the present embodiment, a specific example of a technique for limiting the scene selection range by each slave unit 2 is disclosed.

  As shown in FIG. 17, the handset 2 is provided with an area setting unit 23 for specifying the areas A1 to A3 to be installed. The area setting unit 23 is configured using a DIP switch or the like, and defines areas A1 to A3 in which the operation of the child device 2 is effective. For example, when only one area A1 to A3 is set as the effective range, the area setting unit 23 selects only one area A1 to A3 and sets the effective range of operation of the slave unit 2 to two areas. In the case of A1 to A3, two areas A1 to A3 are selected, and in a case where one slave unit 2 operation is effective for three areas A1 to A3, all areas A1 are selected. Select ~ A3. Each slave unit 2 can select five types of scenes (including a scene in which all the lighting fixtures 3 in the areas A1 to A3 are turned off), and each slave unit 2 can be operated in the area setting unit 23. Since the effective range is defined, it is possible to specify the scene of the dimming scene setting table registered in the master unit 1 by transmitting the combined data to the master unit 1. For example, when the area 5 is divided into three areas A1 to A3 by the partition 5, the corresponding areas A1 to A3 and the scene type selected by the switch SW2 are transmitted by the slave unit 2 provided in each area A1 to A3. Thus, it becomes possible to select one of the patterns P2 shown in Table 1.

  On the other hand, the master unit 1 is provided with a slave unit operation prohibition setting unit 14 configured by combining a switch and a display unit. The slave unit operation prohibition setting unit 14 receives the slave units 2 as shown in Table 9 when the areas A1 to A3 set by the area setting unit 23 and the type of scene selected by the switch SW2 are transmitted from the slave unit 2. It has a function of referring to the operation permission table to determine whether or not to permit the operation. In Table 9, “O” in the operation column indicates that the operation is valid, and “X” indicates that the operation is invalid. In short, the handset operation permission table is used for determining whether the handset 2 on which the switch SW2 is operated is valid or invalid. If the handset 2 is invalid, the content received from the handset 2 is discarded. When the slave unit 2 has a function of displaying an error, when the master unit 1 discards the content received from the slave unit 2, error information is returned to the slave unit 2 and displayed on the slave unit 2 You may do it.

  As described above, by providing the slave unit operation prohibition setting unit 14 in the master unit 1, operation of only a specific slave unit 2 is effective when there are a plurality of slave units 2 in one space. It becomes possible to. Moreover, by providing the area setting unit 14 in the child device 2, it is possible to prohibit the operation of the child device 2 from reaching another space divided by the partition 5. Other configurations and operations are the same as those of the first embodiment.

(Embodiment 14)
In the present embodiment, as shown in FIG. 18, a lamp attachment / detachment detection unit 34 that detects attachment / detachment of the lamp 31 in the lighting fixture 3 and a clock unit 35 that measures the cumulative lighting time of the lamp 31 are provided. In general, it is known that the light output of the lamp 31 decreases with the cumulative lighting time, and the relationship between the attenuation rate of the light output with respect to the initial luminous flux and the cumulative lighting time is substantially constant depending on the specifications of the lamp 31. Therefore, when the number of lighting fixtures 3 is determined based on the initial luminous flux in the lighting design, there is a possibility that the designed illuminance cannot be obtained when the cumulative lighting time is increased. Moreover, if the number of the lighting fixtures 3 is determined based on the final light flux before the replacement of the lamp 31, the initial illuminance becomes too high and power is consumed wastefully.

  Therefore, in the present embodiment, in order to reduce the change in the luminous flux while the lamp 31 is being operated, the dimming level is set low immediately after the replacement of the lamp 31, and the dimming time is adjusted as the cumulative lighting time increases. The light level is controlled to be high. The clock unit 35 incorporates a non-volatile memory such as an EEPROM in order to store the cumulative lighting time even during a period in which power is not supplied to the lighting fixture 3. On the other hand, the lamp attachment / detachment detection unit 34 can be realized by providing a push button switch 37 in the socket 36 as shown in FIG. 19, for example, after the lamp 31 is separated from the push button switch 37 when the lamp 31 is replaced. When the push button switch 37 is pushed again by mounting the lamp 31, the accumulated lighting time accumulated in the nonvolatile memory is reset. Instead of providing the push button switch 37 on the socket 36 as the lamp attachment / detachment detection unit 34, a switch for manual operation may be provided.

  In the lighting circuit control unit 30 provided in the lighting fixture 3, when the dimming level is given from the master unit 1, the actual dimming level is determined by multiplying the magnification according to the accumulated lighting time measured by the clock unit 35. Then, the luminous flux from immediately after the replacement of the lamp 31 to the next replacement is kept substantially constant. By such an operation, the light output of each lighting fixture 31 can be kept substantially constant regardless of the cumulative lighting time, so that the lighting design can be appropriately performed and energy saving can be achieved. Other configurations and operations are the same as those of the first embodiment.
