Below, a preferred embodiment of the present invention will be described in detail with reference to the drawings.

[First embodiment]
1 to 22 show a lighting control system according to a first embodiment of the present invention. The lighting control system A1 of this embodiment includes a plurality of lighting devices L, a control device Ct, and a mobile terminal Mt. The lighting control system A1 is a system in which the control device Ct controls the lighting of the plurality of lighting devices L using wireless communication.

[Lighting device L]
The lighting devices L are used, for example, for indoor lighting, and are installed at various locations such as ceilings, walls, floors, and entrances. The lighting devices L may also be configured for outdoor lighting. The specific form of the lighting device L is not limited in any way, and various forms such as straight tube lighting, high ceiling lighting, ceiling lights, downlights, base lights, and spotlights can be appropriately adopted. In the following description, the lighting device L is referred to as the lighting device L when describing the general configuration of the lighting device L, and the lighting devices L1...Ln and other symbols may be appropriately used when distinguishing between the multiple lighting devices L. The multiple lighting devices L in Figures 1, 6, 7, 14, and 22 may have the same configuration, may have a part in common with each other, or may have different configurations and forms. In the following description, unless otherwise specified, a case in which the multiple lighting devices L have the same configuration will be described as an example.

FIG. 2 is a block diagram of the lighting device L. The lighting device L includes a light source unit 11, a control unit 12, a memory unit 13, a wireless communication unit 14, and a power supply unit 15.

The light source unit 11 is a part that performs the light emitting function in the lighting device L. There are no limitations on the specific configuration of the light source unit 11, and it may, for example, be composed of a board and a number of LEDs mounted in a row on the board. In addition, the lighting device L may appropriately have a transparent or translucent cover (not shown) that transmits the light from the light source unit 11.

The light source unit 11 has, for example, multiple types of LEDs that emit different wavelengths. By adjusting the ratio at which the multiple types of LEDs emit light, the light source unit 11 can emit light of various color temperatures. The light source unit 11 emits light such as daylight color (6500K), cool white (5000K), warm white (3500K), and incandescent color (3000K).

The control unit 12 controls the light source unit 11 and the power supply unit 15 based on, for example, a lighting control signal from the control device Ct, thereby performing color adjustment control and dimming control of the lighting device L. The specific configuration of the control unit 12 is not particularly limited, and may be, for example, a CPU. The storage unit 13 stores information necessary for the control of the control unit 12, and may be, for example, a semiconductor memory. Note that the storage unit 13 is not limited to being built into the housing (not shown) of the lighting device L, and may be detachably provided outside the housing of the lighting device L.

The wireless communication unit 14 is a communication unit for performing wireless communication with the control device Ct and other lighting devices L that constitute the communication network, and transmits and receives wireless signals. The wireless communication unit 14 is connected to the control unit 12 by, for example, UART (Universal Asynchronous Receiver Transmitter) communication, but is not limited to this.

Examples of the functions of the wireless communication unit 14 include receiving data from the control device Ct and transmitting a signal included in the received data to the control unit 12. It also transmits an acknowledgement signal indicating that the data has been received to the control device Ct. It may also transmit a status information signal indicating the operating status of the lighting device L to the control device Ct.

In this embodiment, identification information such as a unique lighting device ID possessed by each of the multiple lighting devices L is stored in the wireless communication unit 14. Specific examples of the identification information are not particularly limited, and include, for example, a MAC (Media Access Control) address and location information. In the following description, a MAC address is used as the identification information of the lighting device L. Note that the identification information may be stored in a component other than the wireless communication unit 14, and may be stored in the memory unit 13, for example. When the wireless communication unit 14 recognizes that one of the received signals is a signal for the lighting device ID of its own device, it transmits the signal to the control unit 12.

The wireless communication by the wireless communication unit 14 is not limited in any way, and in this embodiment, wireless communication using the first protocol is described. The communication frequency of the wireless communication using the first protocol is not limited in any way, and examples include the 920 MHz band, the 2.4 GHz band, the 5 GHz band, and the 13.56 MHz band. Specific examples of the first protocol are not particularly limited, and examples include Bluetooth (registered trademark) including BLE (Bluetooth Low Energy), Zigbee (registered trademark), Wi-Fi (registered trademark), or a proprietary protocol.

In this embodiment, a mesh network shown in FIG. 22 can be constructed by a plurality of lighting devices L and a control device Ct using a unique protocol that uses a first wireless radio wave in the 2.4 GHz band, for example. In the mesh network, a first wireless communication is performed. Since the first protocol is used to transfer various data between the plurality of lighting devices L as described below, a protocol that can construct a mesh network while ensuring the transfer speed and reliability required for the data transfer is selected.

In this embodiment, the control device Ct is the root node of the mesh network. Any one of the multiple lighting devices L may function as a GM (gateway module). The gateway module is the root node of the cluster and is connected to the control device Ct. At this time, the gateway module may build a mesh network together with other gateway modules and communicate with the control device Ct. The gateway module constantly evaluates the communication quality with other gateway modules and the control device Ct, and automatically connects to the one with the best communication quality. Similarly, the lighting device L constantly evaluates the communication quality with other lighting devices L or gateway modules, and automatically connects to the one with the best communication quality. The hardware configuration is the same for both the normal lighting device L and the lighting device L functioning as a gateway module. The lighting device L may be equipped with different software, or may be switched between operating as a normal lighting device L or as a gateway module by mode switching.

The power supply unit 15 is for supplying the light source unit 11, the control unit 12, the wireless communication unit 14, etc. with the power required for their operation. The power supply unit 15 has a function as an AC/DC converter that converts commercial AC 100V or 200V power into DC power, a voltage transformation function, etc.

[Control device Ct]
The control device Ct performs lighting control of the multiple lighting devices L. In this embodiment, the control device Ct is installed in a location where wireless communication with the multiple lighting devices L is possible, such as a room in which the multiple lighting devices L are installed. The lighting control system A1 is required to include at least one control device Ct, and may be configured to include multiple control devices Ct in other configurations.

FIG. 3 is a block diagram of an example of a control device Ct. The control device Ct in this example is configured to have a main function of performing lighting control of multiple lighting devices L, for example referred to as a base module. In this embodiment, the control device Ct includes a control unit 22, a storage unit 23, a wireless communication unit 24, and a power supply unit 25. Note that the control device Ct may also be configured to further include a display unit used for initial setup operations, etc., of the control device Ct.

The control unit 22 is a main component that controls the lighting of multiple lighting devices L, and is used to control each part of the control device Ct. For example, the control unit 22 transmits a control signal to the wireless communication unit 24 so that the control signal is transmitted to the target lighting device L. The specific configuration of the control unit 22 is not particularly limited, and may be, for example, a CPU. The storage unit 23 is used to store information such as programs and setting conditions required for the control of the control unit 22, and may be, for example, a semiconductor memory or a hard disk drive.

The wireless communication unit 24 is for wireless communication with the wireless communication units 14 of the multiple lighting devices L. The frequency band of the wireless communication unit 24 and the wireless communication standard it complies with are wireless communication using the first protocol described above. In the example shown in FIG. 22, the control device Ct forms a mesh network together with the multiple lighting devices L. The wireless communication unit 24 wirelessly transmits, for example, lighting control data from the control unit 22 to the multiple lighting devices L. Note that the control device Ct has, in addition to the wireless communication unit 24, a communication circuit for wireless communication or wired communication via a public communication line or a LAN (Local area network). The public communication line is, for example, an Internet communication line network, a mobile phone line network conforming to the LTE (Long Term Evolution) standard, 5G, 6G, or a combination of these.

The power supply unit 25 is for supplying the control unit 22, the wireless communication unit 24, etc. with the power required for their operation. The power supply unit 25 has a function as an AC/DC converter that converts commercial AC 100V or 200V power into DC power, a voltage transformation function, etc.

After pairing, which will be described later, the control device Ct holds identification information such as the lighting device IDs of the multiple lighting devices L, which are stored, for example, in the storage unit 23. The identification information held by the control device Ct may be, for example, the MAC address or location information of the lighting device L as the lighting device ID.

The control device Ct may be configured as a standalone dedicated device, or may be configured, for example, as a switch for controlling the lighting state of the lighting device L. When the control device Ct is configured as a switch, it may be attached, for example, to a wall surface or to an open storage space in the wall surface.

[Mobile terminal Mt]
The mobile terminal Mt is a terminal for controlling the lighting states of the multiple lighting devices L in the lighting control system A1. There are no limitations on the specific configuration of the mobile terminal Mt, and examples of the mobile terminal Mt include a notebook PC, a tablet terminal, and a smartphone.

As shown in FIG. 4, the mobile terminal Mt of this embodiment includes a display unit 31, a control unit 32, a memory unit 33, a wireless communication unit 34, and a power supply unit 35.

The display unit 31 is for displaying information and images necessary for operating the mobile terminal Mt. The display unit 31 is, for example, a liquid crystal display or an organic EL display. If the mobile terminal Mt is a tablet terminal, a smartphone, or the like, the display unit 31 may be configured as a touch panel and may also serve as an operation unit. Furthermore, if the mobile terminal Mt is a notebook PC, the mobile terminal Mt may be equipped with, for example, a keyboard and a mouse.

The wireless communication unit 34 performs wireless communication via a public communication line or a LAN (Local area network). The wireless communication unit 34 performs wireless communication, for example, via a mobile phone communication network conforming to the LTE standard. This enables the mobile terminal Mt to communicate with the control device Ct and the cloud CL.

The control unit 32 is for controlling each part of the mobile terminal Mt. The specific configuration of the control unit 32 is not particularly limited, and may be, for example, a CPU. The storage unit 33 is for storing information such as programs and setting conditions required for the control of the control unit 32, and may be, for example, a semiconductor memory.

The memory unit 33 or the wireless communication unit 34 may store identification information of the mobile terminal Mt. The identification information is a unique mobile terminal ID possessed by the mobile terminal Mt.

The power supply unit 35 is for supplying the power required for the operation of the display unit 31, the control unit 32, the wireless communication unit 34, etc. The power supply unit 35 may, for example, function as an AC/DC converter that converts commercial AC 100V or 200V power into DC power, may have a voltage transformation function, etc., or may be a rechargeable battery. The battery may be charged using either a contact charger or a non-contact charger.

The mobile terminal Mt may further have an imaging unit. The imaging unit captures images of external objects, etc. The imaging unit may include, for example, a CMOS (Complementary Metal-Oxide-Semiconductor) sensor. The imaging unit performs the function of converting external objects, etc. into digital images. The imaging unit may also be configured to be capable of capturing video.

[Cloud CL]
The cloud CL is an example of a server in the lighting control system A1. The server of the present invention may be a cloud CL virtually configured, for example, by a commercial cloud service on the Internet, which is a public communication line, or may be configured by a PC or the like installed at a predetermined location. As shown in FIG. 1, the cloud CL has an analysis unit 61, a storage unit 62, and a communication unit 63. It is preferable that the cloud CL is located in a country. On the other hand, even if the cloud CL is located outside the country, if the function, role, and effect of the system in the present invention are achieved in the country by the setting person using a mobile terminal Mt in the country and the control device Ct located in the country transmitting lighting control signals to multiple lighting devices L, the cloud CL may be considered as one of the modified examples of the embodiment.

The analysis unit 61 performs analysis and control to realize the lighting control method of the lighting control system A2. The analysis unit 61 may be, for example, a CPU.

The memory unit 62 stores various information in the lighting control system A1, and may be implemented using semiconductor memory, a hard disk, or the like. The communication unit 63 communicates with the mobile terminal Mt, the control device Ct, and the like via a public communication line, and is capable of either or both wired and wireless communication.

Next, an example of a lighting control method for lighting control system A1 will be described below.

First, the method of setting up preparatory steps in the lighting control method of the lighting control system A1 will be described below with reference to Figs. 1 and 5. This method of setting up preparatory steps is not a required setting in the lighting control method of the present invention, and may be adopted as appropriate at the discretion of the person setting up the setting.

First, the power supply of the multiple lighting devices L is turned ON (step S01-1). The specific work and operation for turning ON the lighting devices L are not limited in any way. For example, the lighting devices L may be configured so that the light source unit 11 lights up when they are connected to an external power source, or may be configured so that the lighting device lights up when a specific power switch (not shown) is operated after the lighting device L is connected to an external power source.

When the lighting devices L are powered on, they are turned on in a first lighting state (step S01-2). The first lighting state is the lighting state of the lighting devices L immediately after the power is turned on, and is the lighting state that is stored as an initial setting in the control unit 12, storage unit 13, etc., when the lighting devices L are shipped. When the lighting devices L start receiving lighting control signals, etc., from the control devices Ct, etc., lighting according to the lighting control instructions is given priority over lighting in the first lighting state.

Meanwhile, in the mobile terminal Mt, the person setting it up operates the display unit 31 to start the setting work for pairing. In the mobile terminal Mt, the control unit 32 causes the wireless communication unit 34 to transmit a setting start command signal Sg01 (step S02-1). The setting start command signal Sg01 includes an instruction to turn on the lighting device L in the second lighting state during the setting work for pairing.

The second lighting state is a lighting state different from the first lighting state. There are no limitations on the specific combination of the first lighting state and the second lighting state. For example, various combinations can be selected, such as a combination in which the first lighting state and the second lighting state have different dimming rates of the lighting device L, a combination in which the color adjustment rates are different, or a combination in which one is a constant lighting state and the other is a flashing lighting state. In this example, a case will be described in which the dimming rate in the first lighting state is 100% and the dimming rate in the second lighting state is 20%.

The setting start command signal Sg01 transmitted from the mobile terminal Mt is received by the wireless communication unit 24 of the control device Ct. The control unit 22 of the control device Ct converts the setting start command signal Sg01 into a form that can be transmitted by wireless communication using the first protocol, or reads out a control command signal Sg02 previously stored in the storage unit 23 and transmits this control command signal Sg02 from the wireless communication unit 24. At the time of transmission, pairing has not yet been performed, so the signal is transmitted by so-called broadcast communication, which does not specify which lighting device L is the target (step S02-2).

The control command signal Sg02 transmitted from the control device Ct is received by the wireless communication unit 14 of the multiple lighting devices L. In each of the multiple lighting devices L, when the control command signal Sg02 is received by the wireless communication unit 14, the control unit 12 turns on the light source unit 11 in the second lighting state in accordance with the second lighting state information contained in the control command signal Sg02 (step S02-3). Through the above preparations, a state in which the multiple lighting devices L are turned on in the second lighting state (dimming rate 20%) is achieved, which can be visually confirmed by the person setting up the system.

Next, the main components of the lighting control method of the lighting control system A1 will be described below.

First, the control device Ct acquires distance information between the multiple lighting devices L and the control device Ct by transmitting and receiving wireless signals between the multiple lighting devices L and the control device Ct. There are no limitations on the specific method of acquiring distance information by transmitting and receiving wireless signals. For example, the RSSI value itself, which is the reception strength when a wireless signal transmitted from one device is received by the other device, may be used as the distance information. Alternatively, the difference between the transmission power when one device transmits a wireless signal and the reception strength when the other device receives the wireless signal, corresponds to the communication loss of the communication path. The communication loss is correlated with the communication distance. This communication loss may be treated as distance information. In the following explanation, an example will be described in which the reception strength (RSSI value) when a wireless signal is received is treated as distance information.

First, each of the multiple lighting devices L transmits an identification signal Sg1 including identification information from the wireless communication unit 14 (step S1). The identification signals Sg1 from the multiple lighting devices L are received by the wireless communication unit 24 of the control device Ct (step S2-1). The control unit 22 of the control device Ct checks the identification information included in the identification signal Sg1 and the reception strength (RSSI value) of the identification signal Sg1. The control unit 22 generates a device information signal Sg2 including the identification information and reception strength (RSSI value) of the multiple lighting devices L, and transmits it from the wireless communication unit 24 to the mobile terminal Mt (step S2-2).

The identification signal Sg1 from the multiple lighting devices L may include type information of each lighting device L. Type information is information indicating the equipment configuration of each lighting device L, such as straight tube lighting, high ceiling lighting, ceiling light, down light, base light, spot light, etc., and various configurations may be adopted, such as names of these being expressed directly as character data, or replaced with corresponding symbols or codes. Each lighting device L may transmit type information stored in advance in the memory unit 13, for example, as the identification signal Sg1 together with the identification information. In this case, the device information signal Sg2 may include type information of the multiple lighting devices L.

Meanwhile, as shown in Figures 6 and 8, a property information signal Sg3 is sent from the setting terminal PC to the cloud CL (step S3-0). The property information signal Sg3 includes property information of the lighting control system A1. The property information is information including attributes of the location where multiple lighting devices L are installed. Specific examples of property information include the size and height of the property, the number of lighting devices L installed, the type of lighting devices L, the number of groups to be collectively controlled, the lighting control schedule, and whether or not sensors (human detection, illuminance) are required. The analysis unit 61 of the cloud CL stores the property information of the received property information signal Sg3 in the memory unit 62. Figure 9 shows an example of property information stored in the memory unit 62.

The mobile terminal Mt receives the device information signal Sg2 and the property information signal Sg3 (step S3-1). The mobile terminal Mt may receive the property information signal Sg3 by operating the mobile terminal Mt shown in FIG. 10, for example. A property information screen is displayed on the display unit 31 in the figure. Areas for property ID, acquisition, etc. are set on the property information screen. When the setter specifies a property ID (AB in the example shown) and touches the "Acquire" icon, a specified request signal is transmitted from the mobile terminal Mt to the cloud CL, and in response to this request signal, a property information signal Sg3 is transmitted from the communication unit 63 of the cloud CL, and the wireless communication unit 34 of the mobile terminal Mt receives the property information signal Sg3.

The mobile terminal Mt may compare the number of lighting devices L included in the device information signal Sg2 with the number of lighting devices L included in the property information signal Sg3. If the number of lighting devices L included in the device information signal Sg2 differs from the number of lighting devices L included in the property information signal Sg3, inconsistency information may be displayed on the display unit 31 (step S3-2). FIG. 11 shows an example of how inconsistency information is displayed. A number confirmation screen is displayed on the display unit 31. The number displayed as "Property Information" is the number of lighting devices L included in the property information signal Sg3. The number displayed as "Site Information" is the number of lighting devices L included in the device information signal Sg2. Since these numbers differ, in this example, a comment "Does not match" is displayed.

To realize steps S3-1 and S3-2, a program may be stored in the storage unit 33 of the mobile terminal Mt that causes a computer provided in the mobile terminal Mt to execute the steps of acquiring the number of the plurality of lighting devices L from the cloud CL, acquiring the number of the plurality of lighting devices L from the control device Ct, and displaying inconsistency information on the display unit 31 if the number of the plurality of lighting devices L acquired from the cloud CL does not match the number of the plurality of lighting devices L acquired from the control device Ct.

Then, the mobile terminal Mt divides the lighting devices L into multiple provisional groups based on the reception strength (RSSI value) as distance information (step S3-3). Figure 7 shows an example of the arrangement of multiple lighting devices L. In this example, multiple lighting devices L1 to L12 are arranged in a matrix. The distance between adjacent lighting devices L in the left-right and up-down directions in the figure is equal. Furthermore, the control device Ct is arranged at the bottom left of the figure with respect to the multiple lighting devices L. The distance from the control device Ct to lighting device L9 is the shortest, and lighting device L4 is the longest.

The control unit 32 of the mobile terminal Mt groups the lighting devices L1 to L12 into a number of provisional groups Ga, Gb, and Gc in this example based on the distance information of each of the lighting devices L1 to L12. The provisional group Ga is a group that is relatively close to the control device Ct, and in the illustrated example, the lighting devices L1, L5, L6, L9, and L10 are grouped into the provisional group Ga. The provisional group Gc is a group that is relatively far from the control device Ct, and in the illustrated example, the lighting devices L3, L4, L8, and L12 are grouped into the provisional group Gc. The provisional group Gb is a group that is between the provisional group Ga and the provisional group Gc in terms of distance from the control device Ct. In the illustrated example, the lighting devices L2, L7, and L11 are grouped into the provisional group Gb. The number of the provisional groups is not limited to three, and may be two, four, or more.

Then, the setter uses the mobile terminal Mt to select a provisional group (step S4-1). Figure 12 shows an example of a display on the display unit 31 of the mobile terminal Mt. This figure shows an example of a "lighting device list," and an area labeled "Gb (normal)" is provided at the top of the screen. When the setter touches this area, a pull-down menu appears displaying options such as "Ga (close)," "Gb (normal)," and "Gc (distant)." The setter selects any provisional group from the pull-down menu.

When a temporary group is selected, the control unit 32 of the mobile terminal Mt displays on the display unit 31 the identification information of the lighting devices L belonging to the selected temporary group Gb (step S4-1). In the example shown in FIG. 12, the MAC addresses are displayed as the identification information of the lighting devices L2, L7, and L11 belonging to the temporary group Gb. When displaying the MAC addresses as the identification information, the MAC addresses themselves may be displayed in their entirety, or may be abbreviated to an abbreviation or the like according to a predetermined rule. Furthermore, in the example shown, in addition to the identification information, type information and distance information (RSSI value) of each lighting device L are displayed.

In order to execute steps S3-1, S3-3, and S4-1, a program may be stored in the storage unit 33 of the mobile terminal Mt that causes a computer (control unit 32) provided in the mobile terminal Mt to execute the steps of receiving distance information between the multiple lighting devices L and the control device Ct obtained by transmitting and receiving wireless signals between the multiple lighting devices L and the control device Ct, receiving type information of the multiple lighting devices L, grouping the multiple lighting devices L into multiple provisional groups based on the distance information, and displaying on the display unit 31 one or more lighting devices L belonging to a provisional group selected from the multiple provisional groups and the type of the lighting device L.

Next, the person setting up selects the lighting device L to be set from among the lighting devices L displayed on the display unit 31 (step S5-1). In the example shown in FIG. 13, the person setting up selects the lighting device L2. The control unit 32 of the mobile terminal Mt transmits a property information signal Sg3 including the MAC address of the selected lighting device L. The property information signal Sg3 includes, for example, a command to turn on the target lighting device L in a third lighting state that is different from the second lighting state. There are no limitations on the specific example of the third lighting state, and in this example, it is set to a flashing lighting state.

The control device Ct receives the property information signal Sg3 transmitted from the mobile terminal Mt. The control unit 22 of the control device Ct converts the property information signal Sg3 into a lighting control signal Sg4 of the first protocol, and transmits the lighting control signal Sg4 to the MAC address of the target lighting device L (step S5-2).

When the lighting device L2 receives the lighting control signal Sg4 addressed to its own device identification information (MAC address), the control unit 12 turns on the light source unit 11 in the third lighting state (flashing lighting state) (step S5-3, FIG. 14). The setting person visually checks that the lighting device L2 is lit in the third lighting state (flashing lighting state). The setting person determines the regular group to be assigned to the lighting device L2 from the multiple regular groups G1 to G3. In the illustrated example, the lighting devices L1 to L4 aligned horizontally in the figure are grouped into regular group G1, the lighting devices L5 to L8 are grouped into regular group G2, and the lighting devices L9 to L12 are grouped into regular group G3.

As shown in FIG. 13, the display unit 31 of the mobile terminal Mt displays, for example, a setting window for the selected lighting device L2. A "Group" area is set in this setting window. When this area is touched, the group numbers of the regular groups, 1, 2, 3, ..., are displayed in a pull-down menu. As shown in FIG. 15, the setter selects "1" corresponding to the regular group G1 from the pull-down menu and touches the "Set" button. The control unit 22 of the mobile terminal Mt automatically assigns addresses to the lighting devices L2 grouped into the regular group G1 (step S6). In other words, the setter can operate the "Set" button on the display to automatically assign addresses, thereby reducing the time and effort required of the setter to input individual addresses.

There are no limitations on the specific example of the address that the control unit 22 automatically assigns. In this example, the address of the lighting device L2 is assigned as (01.01) (see FIG. 22).

As shown in FIG. 16, the control unit 32 of the mobile terminal Mt may hide the lighting device L2 to which an address has been assigned in the lighting device list on the display unit 31. As a result, only the lighting devices L7 and L11 that belong to the provisional group Gb and to which no address has yet been assigned are displayed in the lighting device list.

As shown in FIG. 17, the above steps S4-1 to S6 are repeated. This sequentially sets the addresses of the lighting devices L7 and L11. That is, by repeating steps S5-1 to S6, when the address setting of the lighting devices L7 and L11 is completed, as shown in FIG. 18, none of the lighting devices L is displayed in the lighting device list on the display unit 31. Furthermore, by repeating steps S4-1 to S6, the setting of regular groups and assignment of addresses are completed for the multiple lighting devices L grouped into the provisional groups Ga and Gc.

The control unit 32 of the mobile terminal Mt confirms that there are zero lighting devices L that have not yet been assigned an address, and automatically sets a cluster (step S7-1). For example, as shown in FIG. 22, the cluster is set by setting a lighting device L to be a GM (gateway module) for each of the regular groups G1 to G3. In the illustrated example, the last two digits of the addresses of the lighting devices L1, L5, and L9 set as GMs (gateway modules) are set to "00". The lighting devices L1, L5, and L9 set as GMs (gateway modules) communicate wirelessly with the control device Ct, and the lighting devices L1, L5, and L9 communicate wirelessly with each other. The lighting devices L of the GMs (gateway modules) included in the regular groups G1 to G3 communicate wirelessly with their respective GMs (gateway modules).

Then, the control unit 22 of the mobile terminal Mt transmits setting information of the multiple lighting devices L to the control device Ct and the cloud CL (step S7-2). The setting information includes the regular group, addresses, etc. of the multiple lighting devices L. The control unit 22 wirelessly transmits a setting signal Sg5 including the setting information from the wireless communication unit 24 to the cloud CL and the control device Ct.

When the wireless communication unit 24 of the control unit 22 of the control device Ct receives the setting signal Sg5, the control unit 22 stores the setting information included in the setting signal Sg5 in the storage unit 23. Then, it transmits the setting signal Sg5 to all lighting devices L (step S7-3). When the wireless communication unit 14 of the control units 12 of the multiple lighting devices L receives the setting signal Sg5, the control units 12 store the setting information included in the setting signal Sg5 in the storage unit 13 (step S7-4). This completes the setting work of grouping the multiple lighting devices L into regular groups and assigning addresses. Thereafter, the lighting of the multiple lighting devices L is controlled, for example, by appropriately transmitting lighting control signals from the control device Ct to the multiple lighting devices L.

FIG. 19 shows a setting procedure that can be additionally performed in the above-mentioned lighting control method. In step S11, the setter inputs property information using a web application or the like. Next, in step S12, multiple lighting devices L are installed at the site. In step S13, the property information is downloaded from the cloud CL to the mobile terminal Mt. After checking that the wireless environment at the site is appropriate, the number of lighting devices L installed at the site is confirmed. This confirmation is performed, for example, by the setter visually. If the confirmed number of multiple lighting devices L is correct (step S14: Yes), the setter sets the regular group and address as described above.

As shown in FIG. 20, in this additional setting procedure, for example, a "Check number" button is provided in the lighting device list shown on the display unit 31. When the person setting the setting touches the "Check number" button (step S15), the total number of lighting devices L at the site and the number of lighting devices L for which grouping has not been set are displayed (step S16, FIG. 21). In the example shown, the percentage of the number of lighting devices for which setting has been completed out of the "number of lighting devices", which is the total number of lighting devices L at the site, is displayed as the "progress rate".

In order to execute the additional setting procedure described above, the storage unit 33 may store a program that causes a computer provided in the mobile terminal Mt to execute the steps of assigning a regular group and address selected from a number of regular groups G1 to G3 to a lighting device L selected from a number of lighting devices L, and displaying on the display unit, at the request of the person setting up, the number of lighting devices L to which an address has not yet been assigned.

Next, the operation of the lighting control system A1 will be explained.

According to this embodiment, as shown in Figs. 7 and 12, only lighting devices L that have been grouped into a provisional group selected from provisional groups Ga to Gc are displayed in the lighting device list. This makes it possible to automatically reduce the number of lighting devices L displayed in the list during configuration work by the person configuring the settings. This reduces the burden on the person configuring the settings.

As shown in step S7-1 of FIG. 17 and FIG. 22, in the lighting control system A1, it is confirmed that there are zero lighting devices L with unassigned addresses, and a cluster is automatically set. This makes it possible to avoid setting a cluster by mistake when lighting devices L with unassigned addresses remain, thereby reducing setting errors.

As shown in FIG. 12, the lighting device list displays type information for multiple lighting devices L. This allows the user to improve the efficiency of the configuration process, such as selecting a lighting device L by selecting "this lighting device is a straight tube type" or "this lighting device is a downlight", etc.

As shown in FIG. 21, the number of lighting devices L for which addresses have not been set (or the progress rate) is displayed, allowing the progress of the setting work to be easily and reliably grasped.

As shown in FIG. 11, when the number of lighting devices L according to the property information differs from the number of lighting devices L installed at the site, inconsistency information is displayed on the display unit 31, allowing the setter to automatically ascertain the number of lighting devices L installed at the site without having to visually check it.

As shown in FIG. 16, in the lighting device list, lighting devices L that have been grouped into regular groups are hidden. This makes it possible to reduce the number of lighting devices L displayed.

FIGS. 23 to 26 show other embodiments of the present invention. In these figures, elements that are the same as or similar to those in the above embodiment are given the same reference numerals as in the above embodiment. Furthermore, the configurations of each part in each modified example and each embodiment can be combined with each other as appropriate to the extent that no technical contradictions arise.

[Second embodiment]
23 and 24 show a lighting control system according to a second embodiment of the present invention. A lighting control system A2 of this embodiment employs a pre-preparation setting method different from the pre-preparation in the lighting control system A1 described above.

Steps S01-1, S01-2, S02-1, and S02-2 described with reference to FIG. 5 are executed. In the lighting control system A2 shown in FIG. 23, multiple lighting devices L1, L2, ..., Ln-1, and Ln are arranged. The multiple lighting devices L1, L2, ..., Ln-1 are able to receive the control command signal Sg02 via the wireless communication unit 14. On the other hand, lighting device Ln is far away from the control device Ct, and therefore is unable to receive the control command signal Sg02 via the wireless communication unit 14.

In step S02-3 of FIG. 5, the lighting device L is turned on in the second lighting state. In this embodiment, in each of the multiple lighting devices L, when the control command signal Sg02 is received by the wireless communication unit 14, the control unit 12 turns on the light source unit 11 in the second lighting state in accordance with the information on the second lighting state contained in the control command signal Sg02. On the other hand, when the control command signal Sg02 is not received by the wireless communication unit 14, the lighting device continues to be turned on in the first lighting state.

The control command signal Sg02 may be determined to have been received by the wireless communication unit 14 if the received data can be read without error. However, for example, it may be determined to have been received if the data relating to the radio wave conditions of the control command signal Sg02 in the wireless communication unit 14 (received radio wave strength and S/N ratio) is equal to or greater than a predetermined value. As an example, the predetermined value for the received radio wave strength is set to a value that is larger than the lower limit at which data can be received without error. In this case, even if the control command signal Sg02 can be received without data errors, if the received radio wave strength is equal to or less than the predetermined value, the lighting state will not be changed.

The configurator checks that the lighting device L is still on in the first lighting state even after the control device Ct transmits the control command signal Sg02. In FIG. 23, the lighting device Ln is on in the first lighting state. The configurator adds a relay unit function to the lighting device L (lighting device Ln-1) adjacent to the lighting device Ln. The relay unit function can be added to the lighting device Ln-1 by, for example, changing the software using a wireless signal from the control device Ct. The lighting device Ln-1 to which the relay unit function has been added transfers a signal received by wireless communication of the first protocol to the surrounding lighting devices L. As a result, as shown in FIG. 24, the control command signal Sg02 from the control device Ct is relayed by the lighting device Ln-1 and received by the lighting device Ln. As a result, all lighting devices L, including the lighting device Ln, are on in the second lighting state, and the configurator recognizes that the wireless communication environment for all lighting devices L is now in place.

This embodiment also reduces the burden on the person setting up the system. Furthermore, according to this embodiment, if any of the multiple lighting devices L cannot receive a wireless signal from the control device Ct, the wireless communication environment can be improved by adding a relay function to the other lighting devices L. In other words, by providing a relay function to a specific lighting device (lighting device Ln-1), the wireless communication environment can be improved without having to perform new power supply work, such as installing a separate relay unit.

[Third embodiment]
25 and 26 show a lighting control system and a lighting control method according to a third embodiment of the present invention. In the lighting control system A3 of this embodiment, a plurality of lighting devices L are assigned to the lighting devices L in a layout drawing prepared in advance based on distance information between the plurality of lighting devices L and a control device Ct and distance information between the plurality of lighting devices L.

In FIG. 25, in step S21, each of the multiple lighting devices L transmits an identification signal Sg1 including identification information. Each of the multiple lighting devices L receives the identification signal Sg1 transmitted from the other lighting devices L. Each lighting device L stores the reception strength (RSSI value) of the received identification signal Sg1 in the memory unit 13 (step S22). The reception strengths stored in the memory unit 13 are stored in order of, for example, a predetermined number (e.g., 10) from the highest RSSI value.

Next, the control device Ct transmits a setting start signal Sg7 to the lighting devices L (step S23). The lighting devices L store the reception strength (RSSI value) when receiving the setting start signal Sg7 in the storage unit 13. Next, each of the lighting devices L transmits a device information signal Sg8 to the control device Ct, which includes the reception strength (RSSI value) when receiving the identification signal Sg1 from the other lighting devices L, the reception strength (RSSI value) when receiving the setting start signal Sg7 from the control device Ct, and the identification information (step S25). The control device Ct receives the device information signal Sg8 from the lighting devices L (step S26).

The control device Ct also receives layout plan information of the multiple lighting devices L from the mobile terminal Mt, the cloud CL, etc. (step S27). The layout plan information includes information that 12 lighting devices L are placed at positions Pa to Pm shown in FIG. 26.

Then, the control unit 22 of the control device Ct assigns the multiple lighting devices L to the positions Pa to Pm based on the information contained in the device information signal Sg8 and the layout diagram information (step S28).

To explain a specific example of step S28, first, for the reception strength of the identification signal Sg1 from other lighting devices L stored by each lighting device L, lighting devices L with approximately the same top four reception strengths are extracted. In the example shown in FIG. 26, lighting devices L6 and L7 located at positions Pf and Pg are extracted. For lighting device L6, the reception strengths from lighting devices L2, L5, L7, and L10 are the top four reception strengths and are approximately the same. For lighting device L7, the reception strengths from lighting devices L3, L6, L8, and L11 are the top four reception strengths and are approximately the same.

Next, the reception strength of the setting start signal Sg7 of lighting devices L6 and L7 is compared. Lighting device L6 is closer to the control device Ct than lighting device L7. Therefore, the reception strength by lighting device L6 is stronger than the reception strength by lighting device L7. This makes it possible to determine that lighting device L6 is located at position Pf and lighting device L7 is located at position Pg.

Next, the lighting devices L with approximately the same top three reception intensities are extracted. In the example shown in FIG. 26, the lighting devices L2, L3, L5, L8, L10, and L11 located at positions Pb, Pc, Pe, Ph, Pj, and Pk are extracted. The reception intensities of the setting start signals Sg7 of the lighting devices L2, L3, L5, L8, L10, and L11 are compared. The lighting device L5, which is closest to the control device Ct, has the strongest reception strength, and it is identified as being located at position Pe. The lighting device L8, which is farthest from the control device Ct, has the weakest reception strength, and it is identified as being located at position Ph. The lighting device L10, which has the second strongest reception strength, is located at position Pj, and the lighting device L3, which has the second weakest reception strength, is identified as being located at position Pc.

The remaining lighting devices L2 and L11 do not show a clear difference in reception strength from the control device Ct. Therefore, when comparing the reception strength of the identification signal Sg1 from multiple lighting devices L by lighting device L7, the reception strength from lighting device L11 is stronger than the reception strength from lighting device L2. This identifies lighting device L11 as being located at position Pk. Also, identifies lighting device L2 as being located at position Pb.

Next, for the lighting devices L1, L4, L9, and L12, the reception strength from the control device Ct is strongest in the order of lighting devices L9, L1, L12, and L4. Therefore, it is determined that lighting device L9 is located at position Pi, lighting device L1 is located at position Pa, lighting device L12 is located at position Pm, and lighting device L4 is located at position Pd.

In this way, the lighting control system A3 can automatically determine the layout of the multiple lighting devices L based on the mutual reception strength between the multiple lighting devices L, the reception strength between the multiple lighting devices L and the control device Ct, and layout diagram information of the multiple lighting devices L. This eliminates the need for the setter to perform setup work using a mobile terminal Mt or to visually check the lighting status of the multiple lighting devices L. This further reduces the burden on the setter. Another method for automatically setting temporary groups is to relatively map the reception strength (RSSI value) between the lighting devices in a two-dimensional manner, and set temporary groups from the average value of the distance between each lighting device plotted on this map.

The lighting control system, lighting control method, program, and display method according to the present invention are not limited to the above-described embodiments. The specific configurations of the lighting control system, lighting control method, program, and display method according to the present invention can be freely designed in various ways.
