[0029] Preferred embodiments of the present invention will now be described in detail with reference to the drawings.

[0030] 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.

[0031] [Lighting Device L] The lighting devices L are used, for example, for indoor lighting and are installed in various locations such as ceilings, walls, floors, and entrances. The lighting devices L may also be configured for outdoor lighting. The specific configuration of the lighting devices L is not limited, and various configurations, such as straight tube lighting, high ceiling lighting, ceiling lights, downlights, base lights, and spotlights, can be appropriately adopted. In the following description, the general configuration of the lighting device L will be referred to as the lighting device L, and reference numerals such as lighting devices L1...Ln will be used as appropriate to distinguish 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 share some common features with each other, or may have different configurations or configurations. In the following description, unless otherwise specified, the multiple lighting devices L will be described as having the same configuration.

[0032] 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 storage unit 13, a wireless communication unit 14, and a power supply unit 15.

[0033] The light source unit 11 is a part that performs a light-emitting function in the lighting device L. There are no particular limitations on the specific configuration of the light source unit 11, and it may include, for example, a substrate and a plurality of LEDs mounted in a row on the substrate. The lighting device L may also include a transparent or translucent cover (not shown) that transmits light from the light source unit 11.

[0034] The light source unit 11 includes, 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 of, for example, daylight color (6500K), neutral white (5000K), warm white (3500K), and incandescent color (3000K).

[0035] The control unit 12 controls the light source unit 11 and the power supply unit 15 based on, for example, an illumination control signal from the control device Ct, thereby performing color adjustment control and dimming control of the illumination 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 illumination device L, and may be detachably provided outside the housing of the illumination device L.

[0036] The wireless communication unit 14 is a communication unit for wirelessly communicating 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.

[0037] The wireless communication unit 14 may have the following functions: receive data from the control device Ct, and transmit a signal included in the received data to the control unit 12. The wireless communication unit 14 also transmits an acknowledgement signal indicating that the data has been received to the control device Ct. The wireless communication unit 14 may also transmit a status information signal indicating the operating status of the lighting device L to the control device Ct.

[0038] In this embodiment, identification information such as a unique lighting device ID of 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 media access control (MAC) 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, such as the storage unit 13. When the wireless communication unit 14 recognizes that a received signal is a signal for the lighting device ID of the lighting device itself, it transmits the signal to the control unit 12.

[0039] The wireless communication performed by the wireless communication unit 14 is not limited in any way, and in this embodiment, wireless communication using a first protocol will be described. The communication frequency of the wireless communication using the first protocol is not limited in any way, and examples thereof 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 thereof include Bluetooth (registered trademark) including BLE (Bluetooth Low Energy), Zigbee (registered trademark), Wi-Fi (registered trademark), and proprietary protocols.

[0040] In this embodiment, a plurality of lighting devices L and a control device Ct may establish a mesh network as shown in Fig. 22 using a unique protocol that uses a first radio wave in the 2.4 GHz band, for example. A first wireless communication is performed in the mesh network. Since the first protocol is used to transfer various data between the plurality of lighting devices L as described below, a protocol that can establish the mesh network while ensuring the transfer speed and reliability required for the data transfer is selected.

[0041] In this embodiment, the control device Ct is the root node of the mesh network. Any 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. In this case, 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 of a normal lighting device L and a lighting device L functioning as a gateway module is the same. The lighting device L may be equipped with different software, or may be switched between operating as a normal lighting device L and as a gateway module by mode switching.

[0042] 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 power of 100V or 200V into DC power, a voltage transformation function, etc.

[0043] [Control device Ct] The control device Ct controls the lighting of 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 where multiple lighting devices L are installed. The lighting control system A1 is required to include at least one control device Ct, and may include multiple control devices Ct in other configurations.

[0044] 3 is a block diagram of an example of the control device Ct. The control device Ct in this example is, for example, called a base module, and has a main function of performing lighting control of multiple lighting devices L. 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 further include a display unit used for initial setup of the control device Ct.

[0045] The control unit 22 is a main component that controls the lighting of the multiple lighting devices L, and controls each unit 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 unit 22 transmits a lighting control signal 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 stores 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.

[0046] The wireless communication unit 24 is for wireless communication with the wireless communication units 14 of the multiple lighting devices L. The frequency band and wireless communication standard of the wireless communication unit 24 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. In addition to the wireless communication unit 24, the control device Ct has 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 network compliant with the LTE (Long Term Evolution) standard, 5G, 6G, or the like, or a combination of these.

[0047] The power supply unit 25 is for supplying the power necessary for operation to the control unit 22, the wireless communication unit 24, etc. The power supply unit 25 has a function as an AC / DC converter that converts commercial AC power of 100V or 200V into DC power, a voltage transformation function, etc.

[0048] After pairing, which will be described later, the control device Ct holds identification information such as lighting device IDs of the plurality of lighting devices L, which is stored, for example, in the storage unit 23. The identification information held by the control device Ct may be, for example, a MAC address or location information as the lighting device ID held by the lighting device L.

[0049] The control device Ct may be configured as a standalone dedicated device, or may be configured as, for example, 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 to, for example, a wall surface or an open storage space in the wall surface.

[0050] [Mobile Terminal Mt] The mobile terminal Mt is a terminal for controlling the lighting states of the plurality of lighting devices L in the lighting control system A1. The specific configuration of the mobile terminal Mt is not limited in any way, and examples thereof include a notebook PC, a tablet terminal, a smartphone, etc.

[0051] As shown in FIG. 4, the mobile terminal Mt of this embodiment includes a display unit 31, a control unit 32, a storage unit 33, a wireless communication unit 34, and a power supply unit 35.

[0052] 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 serve as an operation unit. Furthermore, if the mobile terminal Mt is a notebook PC, the mobile terminal Mt may include, for example, a keyboard, a mouse, and the like.

[0053] The wireless communication unit 34 performs wireless communication via a public communication line or a local area network (LAN). For example, the wireless communication unit 34 performs wireless communication via a mobile phone communication network conforming to the LTE standard. This allows the mobile terminal Mt to communicate with the control device Ct and the cloud CL.

[0054] The control unit 32 controls each unit 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 stores information such as programs and setting conditions required for control by the control unit 32, and may be, for example, a semiconductor memory.

[0055] Identification information of the mobile terminal Mt may be stored in the storage unit 33 or the wireless communication unit 34. The identification information is a unique mobile terminal ID that the mobile terminal Mt has.

[0056] The power supply unit 35 supplies the power necessary for the operation of the display unit 31, the control unit 32, the wireless communication unit 34, etc. The power supply unit 35 may have a function as an AC / DC converter that converts commercial AC power of 100V or 200V into DC power, a voltage transformation function, or may be a rechargeable battery. The battery may be charged using either a contact charger or a contactless charger.

[0057] The mobile terminal Mt may further include 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 functions to convert the external objects, etc. into digital images. The imaging unit may also be configured to capture video.

[0058] [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 virtual cloud CL configured, for example, using a commercial cloud service on the Internet, which is a public communication line, or may be configured by a PC or the like installed in a predetermined location. As shown in FIG. 1 , the cloud CL includes an analysis unit 61, a memory unit 62, and a communication unit 63. It is preferable that the cloud CL is located domestically. However, even if the cloud CL is located overseas, it may be considered a variation of the present embodiment as long as the functions, roles, and effects of the present invention are realized domestically by a user using a mobile terminal Mt in Japan and a control device Ct located in Japan transmitting lighting control signals to multiple lighting devices L.

[0059] The analysis unit 61 performs analysis and control to implement the lighting control method of the lighting control system A2. The analysis unit 61 may be implemented by a CPU or the like.

[0060] The storage unit 62 stores various information in the lighting control system A1, and uses a semiconductor memory, a hard disk, etc. The communication unit 63 communicates with the mobile terminal Mt, the control device Ct, etc. via a public communication line, and is capable of either or both of wired communication and wireless communication.

[0061] Next, an example of a lighting control method of the lighting control system A1 will be described below.

[0062] First, a method for setting up preparatory work in the lighting control method of lighting control system A1 will be described below with reference to Figures 1 and 5. This method for setting up preparatory work is not a required setting in the lighting control method of the present invention, and may be adopted as appropriate by a person setting up the preparatory work, etc.

[0063] First, the power of the plurality of lighting devices L is turned on (step S01-1). Specific tasks and operations 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 units 11 are turned on when connected to an external power source, or may be configured so that the lighting devices are turned on when a predetermined power switch (not shown) or the like is operated after being connected to the external power source.

[0064] When the lighting devices L are powered on, they are lit in a first lighting state (step S01-2). The first lighting state is the lighting state of the lighting devices L immediately after powering on, which is the lighting state stored as an initial setting in the control unit 12, storage unit 13, etc. at the time of product shipment of the lighting devices L. When the lighting devices L start receiving lighting control signals, etc. from the control devices Ct, etc., lighting in accordance with the lighting control instructions is given priority over lighting in the first lighting state.

[0065] Meanwhile, in the mobile terminal Mt, the person setting up the mobile terminal Mt 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.

[0066] The second lighting state is a lighting state different from the first lighting state. Specific combinations of the first lighting state and the second lighting state are not limited in any way. 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%.

[0067] 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 via wireless communication using the first protocol, or reads out a control command signal Sg02 pre-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 established, and therefore the signal is transmitted by so-called broadcast communication, which does not specify which lighting device L is the target (step S02-2).

[0068] The control command signal Sg02 transmitted from the control device Ct is received by the wireless communication units 14 of the plurality of lighting devices L. In each of the plurality of lighting devices L, when the control command signal Sg02 is received by the wireless communication units 14, the control unit 12 turns on the light source units 11 in the second lighting state in accordance with the information on the second lighting state included in the control command signal Sg02 (step S02-3). Through the above preparations, a state in which the plurality of lighting devices L are turned on in the second lighting state (dimming rate 20%) is realized, which can be visually confirmed by the person setting up the lighting device.

[0069] Next, the main configuration of the lighting control method of the lighting control system A1 will be described below.

[0070] First, the control device Ct acquires distance information between the plurality of lighting devices L and the control device Ct by transmitting and receiving wireless signals between the plurality of lighting devices L and the control device Ct. The specific method of acquiring distance information by transmitting and receiving wireless signals is not limited in any way. For example, the RSSI value itself, which is the reception strength of a wireless signal transmitted from one device when received by the other device, may be used as 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, a case will be described where the reception strength (RSSI value) when a wireless signal is received is treated as distance information.

[0071] First, each of the lighting devices L transmits an identification signal Sg1 including identification information from its wireless communication unit 14 (step S1). The identification signals Sg1 from the 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 lighting devices L, and transmits the signal from the wireless communication unit 24 to the mobile terminal Mt (step S2-2).

[0072] The identification signal Sg1 from the plurality of lighting devices L may also include type information of each lighting device L. The type information is information indicating the equipment configuration of each lighting device L, such as a straight tube light, high ceiling light, ceiling light, down light, base light, spotlight, etc., and various configurations may be adopted, such as the names of these lighting devices being expressed directly as text data, or replaced with corresponding symbols or codes. Each lighting device L may transmit type information stored in advance in the memory unit 13 as the identification signal Sg1 together with identification information. In this case, the device information signal Sg2 may also include type information of the plurality of lighting devices L.

[0073] Meanwhile, as shown in FIGS. 6 and 8, a property information signal Sg3 is transmitted 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 device L, the number of groups to be collectively controlled, the lighting control schedule, and whether sensors (motion 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 storage unit 62. FIG. 9 shows an example of property information stored in the storage unit 62.

[0074] The mobile terminal Mt receives the device information signal Sg2 and the property information signal Sg3 (step S3-1). Receipt of the property information signal Sg3 by the mobile terminal Mt may be performed, for example, by operating the mobile terminal Mt shown in FIG. 10 . A property information screen is displayed on the display unit 31 in the same figure. The property information screen includes areas for, for example, property ID, acquisition, and the like. When the setter specifies a property ID (in the illustrated example, AB) and touches the "acquire" icon, a predetermined request signal is transmitted from the mobile terminal Mt to the cloud CL. In response to this request signal, the communication unit 63 of the cloud CL transmits the property information signal Sg3, and the wireless communication unit 34 of the mobile terminal Mt receives the property information signal Sg3.

[0075] 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, discrepancy information may be displayed on the display unit 31 (step S3-2). FIG. 11 shows an example of how the discrepancy 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, a comment stating "Does not match" is displayed in this example.

[0076] In order to realize steps S3-1 and S3-2, a program may be stored in the memory 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.

[0077] Next, 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). Fig. 7 shows an example of the arrangement of the lighting devices L. In this example, the lighting devices L1 to L12 are arranged in a matrix. The distances between adjacent lighting devices L in the horizontal and vertical directions in the figure are equal. Furthermore, the control device Ct is arranged in the lower left of the figure with respect to the lighting devices L. The lighting device L9 is the shortest distance from the control device Ct, and the lighting device L4 is the longest.

[0078] In this example, the control unit 32 of the mobile terminal Mt divides the lighting devices L1 to L12 into multiple provisional groups Ga, Gb, and Gc based on the distance information for each of the lighting devices L1 to L12. The provisional group Ga is a group that is relatively close to the control device Ct. In the example shown, 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. In the example shown, the lighting devices L3, L4, L8, and L12 are grouped into the provisional group Gc. The provisional group Gb is a group whose distance from the control device Ct is between the provisional group Ga and the provisional group Gc. In the example shown, the lighting devices L2, L7, and L11 are grouped into the provisional group Gb. The number of provisional groups is not limited to three and may be two, four, or more.

[0079] Next, the settler selects a provisional group using the mobile device Mt (step S4-1). Fig. 12 shows an example of a display on the display unit 31 of the mobile device Mt. This figure shows an example of a "lighting device list," with an area labeled "Gb (normal)" at the top of the screen. When the settler touches this area, a pull-down menu appears displaying options such as "Ga (close)," "Gb (normal)," and "Gc (far)." The settler selects any provisional group from the pull-down menu.

[0080] When a temporary group is selected, the control unit 32 of the mobile terminal Mt displays the identification information of the lighting devices L belonging to the selected temporary group Gb on the display unit 31 (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. The MAC addresses may be displayed as the identification information in their entirety, or may be abbreviated to an abbreviation or the like according to a predetermined rule. In the example shown, in addition to the identification information, type information and distance information (RSSI value) of each lighting device L are also displayed.

[0081] In order to execute steps S3-1, S3-3, and S4-1, a program may be stored in the memory unit 33 of the mobile terminal Mt that causes a computer (control unit 32) provided in the mobile terminal Mt to execute the following steps: receiving distance information between the plurality of lighting devices L and the control device Ct obtained by transmitting and receiving wireless signals between the plurality of lighting devices L and the control device Ct; receiving type information of the plurality of lighting devices L; grouping the plurality of lighting devices L into a plurality of 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 plurality of provisional groups and the types of the lighting devices L.

[0082] Next, the setting person selects a 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 setting person selects 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. Specific examples of the third lighting state are not limited in any way, and in this example, it is set to a flashing lighting state.

[0083] 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).

[0084] 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 confirms that the lighting device L2 is lit in the third lighting state (flashing lighting state). The setting person determines a regular group to be assigned to the lighting device L2 from among the multiple regular groups G1 to G3. In the illustrated example, the lighting devices L1 to L4, which are arranged 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.

[0085] As shown in FIG. 13 , the display unit 31 of the mobile terminal Mt displays a setting window for the selected lighting device L2, for example. A "Group" area is set in this setting window. Touching this area displays a pull-down menu with the group numbers 1, 2, 3, ..., of the regular groups. As shown in FIG. 15 , the setting person selects "1" from the pull-down menu, which corresponds to the regular group G1, and touches the "Set" button. The control unit 22 of the mobile terminal Mt automatically assigns addresses to the lighting devices L2 that have been grouped into the regular group G1 (step S6). In other words, the setting person can automatically assign addresses by operating the "Set" button on the display, thereby eliminating the need for the setting person to input individual addresses.

[0086] There are no particular limitations on the specific example of the address automatically assigned by the control unit 22. In this example, (01.01) is assigned as the address of the lighting device L2 (see FIG. 22).

[0087] 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 addresses have not yet been assigned are displayed in the lighting device list.

[0088] 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, none of the lighting devices L is displayed in the lighting device list on the display unit 31, as shown in Fig. 18. Furthermore, by repeating steps S4-1 to S6, the setting of regular groups and the assignment of addresses are completed for the plurality of lighting devices L grouped into the provisional groups Ga and Gc.

[0089] The control unit 32 of the mobile terminal Mt confirms that there are zero lighting devices L that have not yet been assigned addresses and automatically sets up a cluster (step S7-1). For example, as shown in FIG. 22 , the cluster is set up by setting up a lighting device L to serve as 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 that are set up as GMs (gateway modules) are set to "00." The lighting devices L1, L5, and L9 that are set up as GMs (gateway modules) communicate wirelessly with the control device Ct, and also 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).

[0090] Next, the control unit 22 of the mobile terminal Mt transmits setting information of the plurality of lighting devices L to the control device Ct and the cloud CL (step S7-2). The setting information includes the official groups, addresses, etc. of the plurality of 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.

[0091] 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, the control unit 22 transmits the setting signal Sg5 to all lighting devices L (step S7-3). When the wireless communication units 14 of the control units 12 of the multiple lighting devices L receive the setting signal Sg5, the control unit 22 stores 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, lighting control of the multiple lighting devices L is performed, for example, by appropriately transmitting lighting control signals from the control device Ct to the multiple lighting devices L.

[0092] 19 shows a setting procedure that can be additionally performed in the above-described lighting control method. In step S11, the setting person 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 setting person confirms the number of lighting devices L installed at the site. This confirmation is performed, for example, by visual inspection. If the confirmed number of multiple lighting devices L is correct (step S14: Yes), the setting person sets the authorized group and addresses as described above.

[0093] As shown in Fig. 20 , in this additional setting procedure, for example, a "Confirm Number" button is provided in the lighting device list displayed on the display unit 31. When the person setting the setting touches the "Confirm 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 yet been set are displayed (step S16, Fig. 21 ). In the example shown, the percentage 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."

[0094] 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 selected from a plurality of regular groups G1 to G3 and an address to a lighting device L selected from a plurality of lighting devices L, and displaying, at the request of the setting person, the number of lighting devices L to which addresses have not yet been assigned on the display unit.

[0095] Next, the operation of the lighting control system A1 will be described.

[0096] According to this embodiment, as shown in Figures 7 and 12, the lighting device list displays only lighting devices L that have been grouped into a temporary group selected from any of the temporary groups Ga to Gc. This makes it possible to automatically reduce the number of lighting devices L displayed in the list during the configuration work by the configurator, thereby reducing the burden on the configurator.

[0097] As shown in step S7-1 of Fig. 17 and Fig. 22, the lighting control system A1 confirms that there are zero lighting devices L to which addresses have not been assigned, and then automatically sets a cluster. This makes it possible to avoid erroneously setting a cluster when lighting devices L to which addresses have not been assigned remain, thereby reducing setting errors.

[0098] 12, the lighting device list displays type information for a plurality of lighting devices L. This allows the user to improve the efficiency of the setting work, such as selecting a lighting device L, by selecting, for example, "this lighting device is a straight tube type" or "this lighting device is a downlight."

[0099] As shown in FIG. 21, the number of lighting devices L for which addresses have not yet been set (or the progress rate) is displayed, so that the progress of the setting work can be easily and reliably grasped.

[0100] 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, discrepancy information is displayed on the display unit 31, so that the number of lighting devices L installed at the site can be automatically determined by the person setting up the site without the need to visually check the number.

[0101] 16, in the lighting device list, lighting devices L that have been grouped into regular groups are hidden, thereby making it possible to reduce the number of lighting devices L displayed.

[0102] 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. Furthermore, the configurations of the various parts in each of the modified examples and embodiments can be combined with each other as appropriate within the scope of not causing technical contradictions.

[0103] 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 different setup method for preparation from that of the lighting control system A1 described above.

[0104] 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, a plurality of lighting devices L1, L2, ..., Ln-1, and Ln are arranged. The plurality of 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 from the control device Ct, and therefore is unable to receive the control command signal Sg02 via the wireless communication unit 14.

[0105] 5, the lighting device L is turned on in the second lighting state. In this embodiment, in each of the plurality of 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 included 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 L continues to be turned on in the first lighting state.

[0106] 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, the control command signal Sg02 may be determined to have been received if the data related to the radio wave conditions (received radio wave strength and S / N ratio) of the control command signal Sg02 in the wireless communication unit 14 is equal to or greater than a predetermined value. As an example, the predetermined value of the received radio wave strength is set to a value that is greater than the lower limit at which data can be received without error. In this case, even if the control command signal Sg02 is received without data error, if the received radio wave strength is below the predetermined value, the lighting state will not be changed.

[0107] The configurator confirms that the lighting device L remains lit 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 lit in the first lighting state. The configurator adds relay unit functionality to the lighting device L (lighting device Ln-1) adjacent to the lighting device Ln. Adding the relay unit functionality to the lighting device Ln-1 can be achieved, for example, by modifying the software via a wireless signal from the control device Ct. The lighting device Ln-1, to which the relay unit functionality has been added, forwards signals received via wireless communication under 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 lit in the second lighting state, and the configurator recognizes that the wireless communication environment for all lighting devices L is now in place.

[0108] This embodiment also reduces the burden on the person setting up the system. Furthermore, according to this embodiment, if one 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 another lighting device 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.

[0109] 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 diagram 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.

[0110] 25 , in step S21, each of the plurality of lighting devices L transmits an identification signal Sg1 including identification information. Each of the plurality of lighting devices L receives the identification signal Sg1 transmitted from another lighting device L. Each lighting device L stores the reception strength (RSSI value) of the received identification signal Sg1 in the storage unit 13 (step S22). The reception strengths stored in the storage unit 13 are, for example, a predetermined number (e.g., 10) of signals in descending order of RSSI value.

[0111] Next, the control device Ct transmits a setting start signal Sg7 to the plurality of lighting devices L (step S23). The plurality of 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 plurality of lighting devices L transmits to the control device Ct a device information signal Sg8 including 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 identification information (step S25). The control device Ct receives the device information signal Sg8 from the plurality of lighting devices L (step S26).

[0112] The control device Ct also receives layout plan information of the plurality of 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 arranged at positions Pa to Pm shown in FIG.

[0113] Then, the control unit 22 of the control device Ct allocates the lighting devices L to the positions Pa to Pm based on the information included in the device information signal Sg8 and the layout plan information (step S28).

[0114] To explain a specific example of step S28, first, lighting devices L having approximately the same top four reception intensities of the identification signals Sg1 stored by each lighting device L 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 top four reception intensities from lighting devices L2, L5, L7, and L10 are approximately the same. For lighting device L7, the top four reception intensities from lighting devices L3, L6, L8, and L11 are approximately the same.

[0115] Next, the reception strength of the setting start signal Sg7 from the lighting devices L6 and L7 is compared. The lighting device L6 is closer to the control device Ct than the lighting device L7. Therefore, the reception strength from the lighting device L6 is stronger than the reception strength from the lighting device L7. This allows the lighting device L6 to be determined to be located at position Pf and the lighting device L7 to be determined to be located at position Pg.

[0116] Next, the lighting devices L with approximately the same top three reception intensities are extracted. In the example shown in FIG. 26 , 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 reception intensity of the lighting device L5, which is closest to the control device Ct, is the strongest, and it is identified as being located at position Pe. The reception intensity of the lighting device L8, which is farthest from the control device Ct, is the weakest, and it is identified as being located at position Ph. The lighting device L10, which has the second strongest reception intensity, is located at position Pj, and the lighting device L3, which has the second weakest reception intensity, is identified as being located at position Pc.

[0117] The remaining lighting devices L2 and L11 do not show any clear difference in reception strength from the control device Ct. Therefore, when the reception strength of the identification signal Sg1 from the lighting devices L by the lighting device L7 is compared, the reception strength from the lighting device L11 is stronger than the reception strength from the lighting device L2. This identifies the lighting device L11 as being located at position Pk. Furthermore, it identifies the lighting device L2 as being located at position Pb.

[0118] 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.

[0119] In this way, the lighting control system A3 can automatically determine the location 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 for the multiple lighting devices L. This eliminates the need for the setter to perform setup work using the mobile device 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 may involve processing the reception strength (RSSI value) between lighting devices relative to one another in a two-dimensional map, and setting temporary groups based on the average value of the distances between the lighting devices plotted on this map.

[0120] The lighting control system, lighting control method, program, and display method according to the present invention are not limited to the above-described embodiments, and the specific configurations of the lighting control system, lighting control method, program, and display method according to the present invention can be freely modified in various ways.
