Best Mode for Carrying Out the Invention

[0029] Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

[0030] <First Embodiment> FIGS. 1 to 22 show a lighting control system according to a first embodiment of the present invention. The lighting control system A1 of the present 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 that performs lighting control of a plurality of lighting devices L by the control device Ct using wireless communication.

[0031] 〔Lighting Device L〕 The plurality of lighting devices L are used, for example, for indoor lighting and are installed at various locations such as ceilings, wall surfaces, floor surfaces, entrances and exits. Further, the lighting device L may be configured for outdoor lighting. The specific form of the lighting device L is not limited at all, and various forms such as straight tube lighting, high ceiling lighting, ceiling light, downlight, base light, spotlight, etc. can be appropriately adopted. In the following description, when describing the general configuration of the lighting device L, it is referred to as the lighting device L, and when distinguishing a plurality of lighting devices L, symbols such as lighting devices L1 ··· Ln may be appropriately used. The plurality of lighting devices L in FIGS. 1, 6, 7, 14, and 22 may have the same configuration, may partially share each other, or may have different configurations and different forms. In the following description, unless otherwise specified, the case where a plurality of lighting devices L have the same configuration will be described as an example.

[0032] 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 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. The specific configuration of the light source unit 11 is not limited in any way. For example, it consists of a substrate and a plurality of LEDs mounted in a row on the substrate. Further, the lighting device L appropriately has a transparent or translucent cover (not shown) that transmits the light from the light source unit 11.

[0034] The light source unit 11 has, for example, a plurality of types of LEDs that emit different wavelengths. By adjusting the ratio of the plurality of types of LEDs to 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), incandescent color (3000K), etc.

[0035] The control unit 12 is for performing color adjustment control and dimming control of the lighting device L by controlling the light source unit 11 and the power supply unit 15 based on, for example, a lighting control signal from the control device Ct. The specific configuration of the control unit 12 is not particularly limited and consists of, for example, a CPU. The storage unit 13 is for storing information necessary for the control of the control unit 12 and consists of, 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.

[0036] The wireless communication unit 14 is a communication unit for performing wireless communication with the control device Ct and other lighting devices L constituting the communication network, and transmits and receives wireless signals. The wireless communication unit 14 is connected to the control unit 12, for example, by UART (Universal Asynchronous Receiver Transmitter) communication, but is not limited to this.

[0037] To exemplify the functions of the wireless communication unit 14, it receives data from the control device Ct and transmits the signals included in the received data to the control unit 12. Also, it transmits an acknowledgment signal indicating that it has received the data to the control device Ct. Further, it may 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 the unique lighting device ID of each of the plurality of lighting devices L is stored in the wireless communication unit 14. Specific examples of the identification information are not particularly limited and are, for example, MAC (Media Access Control) addresses and location information. In the following description, a MAC address is adopted as the identification information of the lighting device L. Note that the identification information may be stored in components other than the wireless communication unit 14, for example, it may be stored in the storage unit 13. When the wireless communication unit 14 recognizes that a received signal is a signal for its own lighting device ID, the wireless communication unit 14 transmits the signal to the control unit 12.

[0039] The wireless communication by the wireless communication unit 14 is not limited in any way. In this embodiment, the wireless communication using the first protocol will be 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, 2.4 GHz band, 5 GHz, 13.56 MHz band, etc. Also, 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 protocol of an original standard.

[0040] In this embodiment, the plurality of lighting devices L and the control device Ct can construct a mesh network shown in FIG. 22 by an original protocol using, for example, the first radio wave in the 2.4 GHz band. In the mesh network, the first wireless communication is performed. Since the first protocol is used for transferring various data between the plurality of lighting devices L as described later, a protocol that can ensure the transfer speed and reliability required for those data transfers and can construct a mesh network is selected.

[0041] In this embodiment, the control device Ct is the root node of the mesh network. Any one of the plurality of 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 construct 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 partner with the best communication quality. Similarly, the lighting device L also constantly evaluates the communication quality with other lighting devices L or the gateway module, and automatically connects to the partner with the best communication quality. Both the normal lighting device L and the lighting device L functioning as a gateway module have the same hardware configuration. The software installed in the lighting device L may be made different, or it may be switched to operate as a normal lighting device L or as a gateway module by mode switching.

[0042] The power supply unit 15 is for supplying the power necessary for operation to the light source unit 11, the control unit 12, the wireless communication unit 14, etc. The power supply unit 15 has functions such as an AC / DC converter that converts commercial AC 100V or 200V power into DC power, and a voltage conversion function.

[0043] 〔Control Device Ct〕 The control device Ct performs lighting control of a plurality of lighting devices L. In the case of this embodiment, the control device Ct is installed in a place where wireless communication with a plurality of lighting devices L is possible, such as indoors where a plurality of lighting devices L are installed. The lighting control system A1 only needs to include at least one control device Ct, and may include a plurality of control devices Ct in other configurations.

[0044] FIG. 3 is a block diagram of an example of the control device Ct. The control device Ct in this example is configured to mainly perform functions for controlling the lighting of a plurality of lighting devices L, which is, for example, referred to as a base module. In the present 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 setting operations and the like of the control device Ct.

[0045] The control unit 22 is a main component for controlling the lighting of a plurality of lighting devices L, and is for controlling each part of the control device Ct. For example, the control unit 22 transmits a control signal to the wireless communication unit 24 so as to transmit a lighting control signal to the target lighting device L. The specific configuration of the control unit 22 is not particularly limited, and for example, it consists of a CPU. The storage unit 23 is for storing information such as programs and setting conditions necessary for the control of the control unit 22, and for example, it consists of a semiconductor memory, a hard disk drive, or the like.

[0046] The wireless communication unit 24 is for performing wireless communication with the wireless communication units 14 of a plurality of lighting devices L. The frequency band of the wireless communication unit 24 and the standard of the wireless communication to which it conforms are wireless communication using the above-mentioned first protocol. In the example shown in FIG. 22, the control device Ct constitutes a mesh network together with a plurality of lighting devices L. The wireless communication unit 24 wirelessly transmits, for example, lighting control data from the control unit 22 to a plurality of lighting devices L. Note that, in addition to the wireless communication unit 24, the control device Ct has a communication circuit for performing wireless communication or wired communication via a public communication line or a LAN (Local Area Network). The public communication line is constituted by, for example, any one of an Internet communication line network, a mobile phone line network conforming to the LTE (Long Term Evolution) standard, 5G, 6G, etc., or a combination thereof.

[0047] The power supply unit 25 is for supplying power necessary for operations to the control unit 22, the wireless communication unit 24, and the like. The power supply unit 25 has functions such as an AC / DC converter that converts commercial AC 100V or 200V power into DC power, and a voltage conversion function and the like.

[0048] After the pairing described later, the control device Ct holds identification information such as the lighting device ID of a plurality of lighting devices L, and these are 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 position information as the lighting device ID held by the lighting device L.

[0049] The control device Ct may be configured as a single dedicated device, or may be configured as a switch for operating the lighting state of the lighting device L, for example. When the control device Ct is configured as a switch, it may be attached to a wall surface, for example, or may be attached to an empty storage space on the wall surface.

[0050] 〔Mobile terminal Mt〕 The mobile terminal Mt is a terminal for controlling the lighting states of a plurality of lighting devices L in the lighting control system A1. The specific configuration of the mobile terminal Mt is not limited at all, and examples include a notebook PC, a tablet terminal, a smartphone, and the like.

[0051] As shown in FIG. 4, the mobile terminal Mt of the present 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 operations of the mobile terminal Mt. The display unit 31 is, for example, a liquid crystal display or an organic EL display. When the mobile terminal Mt is a tablet terminal, a smartphone, or the like, the display unit 31 may also serve as an operation unit by being configured as a touch panel. Further, when the mobile terminal Mt is a notebook PC, the mobile terminal Mt may include, for example, a keyboard and a mouse.

[0053] The wireless communication unit 34 performs wireless communication via a public communication line or a LAN (Local Area Network). For example, the wireless communication unit 34 performs wireless communication via a mobile phone communication network conforming to the LTE standard. As a result, the mobile terminal Mt can communicate with the control device Ct and the cloud CL.

[0054] 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, composed of a CPU. The storage unit 33 is for storing information such as programs and setting conditions necessary for the control of the control unit 32 and is composed of, for example, a semiconductor memory or the like.

[0055] The 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 is for supplying power necessary for the operations of the display unit 31, the control unit 32, the wireless communication unit 34, etc. The power supply unit 35 has, for example, a function as an AC / DC converter that converts commercial AC 100V or 200V power into DC power, a voltage conversion function, etc., or is a rechargeable battery. The charging method of the battery may use a contact charger or a non-contact charger.

[0057] The mobile terminal Mt may further have an imaging unit. The imaging unit captures an image of an external object or the like. The imaging unit may include, for example, a CMOS (Complementary Metal-Oxide-Semiconductor) sensor. The imaging unit functions to convert an external object or the like into a digital image. Also, the imaging unit may be configured to be able to capture a moving image.

[0058] 〔Cloud CL〕 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 by, for example, a commercial cloud service or the like 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 desirable for the cloud CL to be in the country. On the other hand, even if the cloud CL is located abroad, if the setter uses the mobile terminal Mt in the country and the control device Ct located in the country transmits a lighting control signal to a plurality of lighting devices L, and the functions, roles, and effects obtained by the system in the present invention are in the country, it may be considered as one of the modified examples of the present embodiment.

[0059] The analysis unit 61 performs analysis and control for realizing the lighting control method of the lighting control system A2. For example, a CPU or the like is used for the analysis unit 61.

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

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

[0062] First, the pre - preparation setting method in the lighting control method of the lighting control system A1 will be described below with reference to FIGS. 1 and 5. This pre - preparation setting method is not an essential setting in the lighting control method according to the present invention and is optionally adopted by the setter or the like as appropriate.

[0063] First, turn on the power supplies of the plurality of lighting devices L (step S01-1). The specific operations and procedures for turning on the power supply of the lighting device L are not limited in any way. For example, the lighting device L may be configured such that the light source unit 11 lights up when connected to an external power supply, or it may be configured to light up after being connected to the external power supply by operating a predetermined power switch (not shown) or the like.

[0064] When the power supplies of the plurality of lighting devices L are turned on, they light up in the first lighting state (step S01-2). The first lighting state is the lighting state of the lighting device L immediately after the power is turned on, and is, for example, the lighting state stored as an initial setting in the control unit 12, the storage unit 13, etc. at the time of product shipment of the lighting device L. When the lighting device L starts receiving a lighting control signal or the like from the control device Ct or the like, thereafter, lighting according to the instruction content of the lighting control takes precedence over lighting in the first lighting state.

[0065] On the other hand, on the mobile terminal Mt, the setter operates the display unit 31 to start the pairing setting work. 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 light up the lighting device L in the second lighting state in the pairing setting work.

[0066] The second lighting state is a lighting state different from the first lighting state. The specific combination of the first lighting state and the second lighting state is not limited in any way. For example, various combinations such as a combination where the dimming rate of the lighting device L is different between the first lighting state and the second lighting state, a combination where the color mixing rate is different, or a combination where one is a constant lighting state and the other is a blinking lighting state can be selected. In this example, the case where the dimming rate in the first lighting state is 100% and the dimming rate in the second lighting state is 20% will be described.

[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 by wireless communication using the first protocol, or reads out the control command signal Sg02 stored in advance in the storage unit 23, and transmits it from the wireless communication unit 24 as this control command signal Sg02. At the time of this transmission, since pairing has not been performed yet, it is transmitted by so-called broadcast communication without specifying which lighting device L it is targeted at (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 unit 14, the control unit 12 turns on the light source unit 11 in the second lighting state according to the information on the second lighting state included in the control command signal Sg02 (step S02-3). Through the above preliminary preparations, a state is realized in which the plurality of lighting devices L are lit in the second lighting state (dimming rate: 20%), and the setter can visually confirm it.

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

[0070] First, by transmitting and receiving wireless signals between the plurality of lighting devices L and the control device Ct, the control device Ct acquires the distance information 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 intensity when a wireless signal transmitted from one side is received by the other side, may be adopted as the distance information. Alternatively, the difference between the transmission power when one side transmits a wireless signal and the reception intensity when the other side 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 description, the case where the reception intensity (RSSI value) when receiving a wireless signal is treated as distance information will be described as an example.

[0071] First, each of the plurality of lighting devices L transmits an identification signal Sg1 including identification information from the wireless communication unit 14 (step S1). The wireless communication unit 24 of the control device Ct receives the identification signal Sg1 from the plurality of lighting devices L (step S2-1). The control unit 22 of the control device Ct confirms the identification information included in the identification signal Sg1 and the reception intensity (RSSI value) of the identification signal Sg1. The control unit 22 generates a device information signal Sg2 including the identification information and the reception intensity (RSSI value) of the plurality of lighting devices L, and transmits it from the wireless communication unit 24 to the mobile terminal Mt (step S2-2).

[0072] Further, the identification signal Sg1 from the plurality of lighting devices L may include type information of each lighting device L. The type information is information indicating the device configuration etc. of each lighting device L. For example, it is straight tube lighting, high ceiling lighting, ceiling light, downlight, base light, spotlight, etc., and various configurations such as those in which these names are directly represented as character data, those replaced with corresponding symbols or codes, etc. may be adopted. Each lighting device L may transmit, for example, the type information stored in advance in the storage unit 13 as the identification signal Sg1 together with the identification information. Also, in this case, the device information signal Sg2 may include the type information of the plurality of lighting devices L.

[0073] On the other hand, 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 the property information of the lighting control system A1. The property information is information including the attributes of the place where the plurality of lighting devices L are installed. Specific examples of the property information include, for example, the size of the property, the height, the number of installed lighting devices L, the type of lighting device L, the number of groups for collective control, the lighting control schedule, the necessity of sensors (presence / absence of people, illuminance), etc.

[0074] The mobile terminal Mt receives the device information signal Sg2 and the property information signal Sg3 (step S3-1). The reception of the property information signal Sg3 by the mobile terminal Mt may be executed by operating the mobile terminal Mt shown in FIG. 10, for example. A property information screen is displayed on the display unit 31 of the figure. In the property information screen, areas such as property ID and acquisition are set. When the setter designates the property ID (AB in the illustrated example) and touches the "acquisition" icon, a predetermined request signal is transmitted from the mobile terminal Mt to the cloud CL, and in response to this request signal, the 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.

[0075] The mobile terminal Mt may compare the number of a plurality of lighting devices L included in the device information signal Sg2 with the number of a plurality of lighting devices L included in the property information signal Sg3. When the number of a plurality of lighting devices L included in the device information signal Sg2 is different from the number of a plurality of lighting devices L included in the property information signal Sg3, mismatch information may be displayed on the display unit 31 (step S3-2). FIG. 11 shows an example of the display of mismatch information. A number confirmation screen is displayed on the display unit 31. The number displayed as "property information" is the number of a plurality of lighting devices L included in the property information signal Sg3. The number displayed as "site information" is the number of a plurality of lighting devices L included in the device information signal Sg2. Since these numbers are different, in this example, a comment "does not match" is displayed.

[0076] In order to realize steps S3-1 and S3-2, a program that causes a computer provided in the mobile terminal Mt to execute steps of obtaining the number of a plurality of lighting devices L from the cloud CL, obtaining the number of a plurality of lighting devices L from the control device Ct, and displaying mismatch information on the display unit 31 when the number of a plurality of lighting devices L obtained from the cloud CL does not match the number of a plurality of lighting devices L obtained from the control device Ct may be stored in the storage unit 33 of the mobile terminal Mt.

[0077] Next, the mobile terminal Mt groups a plurality of lighting devices L into a plurality of temporary groups based on the reception strength (RSSI value) as distance information (step S3-3). FIG. 7 shows an arrangement example of the plurality of lighting devices L. In this example, a plurality of lighting devices L1 to L12 are arranged in a matrix. The distances between the lighting devices L adjacent to each other in the left-right direction and the up-down direction in the figure are equal. Also, the control device Ct is arranged at the lower left in the figure with respect to the plurality of lighting devices L. The distance from the control device Ct is the shortest for the lighting device L9 and the longest for the lighting device L4.

[0078] Based on the distance information of each of the plurality of lighting devices L1 to L12, the control unit 32 of the mobile terminal Mt groups the plurality of lighting devices L1 to L12 into a plurality of temporary groups Ga, Gb, and Gc in this example. The temporary group Ga is a group with a relatively short distance from the control device Ct. In the illustrated example, the lighting devices L1, L5, L6, L9, and L10 are grouped into the temporary group Ga. The temporary group Gc is a group with a relatively long distance from the control device Ct. In the illustrated example, the lighting devices L3, L4, L8, and L12 are grouped into the temporary group Gc. The temporary group Gb is a group with a distance from the control device Ct between the temporary group Ga and the temporary group Gc. In the illustrated example, the lighting devices L2, L7, and L11 are grouped into the temporary group Gb. Note that the number of the plurality of temporary groups is not limited to three, and may be two or four or more.

[0079] Next, the mobile terminal Mt is used to allow the setter to select a temporary group (step S4-1). FIG. 12 shows a display example of the display unit 31 of the mobile terminal Mt. This figure is an example of a "lighting device list", and a region indicated as "Gb (normal)" is provided at the upper part of the screen. When the setter touches the region, for example, "Ga (close)", "Gb (normal)", and "Gc (far)" are displayed in a pull-down manner. The setter selects an arbitrary temporary 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 display of the MAC address as the identification information may be such that the entire MAC address itself is displayed, or it may be displayed in a manner abbreviated as a short symbol or the like according to a predetermined rule. Also, in the illustrated example, in addition to the identification information, the type information and distance information (RSSI value) of each lighting device L are displayed.

[0081] In order to execute step S3-1, step S3-3, and step S4-1, a program that causes a computer (control unit 32) provided in the mobile terminal Mt to perform the steps of receiving distance information between a plurality of lighting devices L and a control device Ct obtained by wireless signal transmission and reception 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 temporary groups based on the distance information, and displaying on the display unit 31 one or more lighting devices L belonging to the temporary group selected from the plurality of temporary groups and the type of the lighting device L may be stored in the storage unit 33 of the mobile terminal Mt.

[0082] Next, the setter 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 setter has selected the lighting device L2. The control unit 32 of the mobile terminal Mt transmits an object information signal Sg3 including the MAC address of the selected lighting device L. The object information signal Sg3 includes, for example, a command to cause the target lighting device L to light in a third lighting state different from the second lighting state. The specific example of the third lighting state is not limited in any way, and in this example, it is set to a blinking 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 an illumination control signal Sg4 of the first protocol, and transmits the illumination control signal Sg4 to the MAC address of the target illumination device L (step S5-2).

[0084] When the illumination device L2 receives the illumination control signal Sg4 addressed to its own device's 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 setter visually confirms the illumination device L2 that is lit in the third lighting state (flashing lighting state). The setter determines the regular group to be assigned to the illumination device L2 from the plurality of regular groups G1 to G3. In the illustrated example, the illumination devices L1 to L4 arranged in the left-right direction in the figure are grouped into the regular group G1, the illumination devices L5 to L8 are grouped into the regular group G2, and the illumination devices L9 to L12 are grouped into the regular group G3.

[0085] As shown in FIG. 13, on the display unit 31 of the mobile terminal Mt, for example, a setting window of the selected illumination device L2 is displayed. In this setting window, a "group" area is set. When touching this area, the group numbers 1, 2, 3,... of the regular groups 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 an address to the illumination device L2 grouped into the regular group G1 (step S6). That is, since the setter automatically has an address assigned by operating the "set" button on the display unit, the trouble of the setter inputting individual addresses can be reduced.

[0086] A specific example of the address automatically assigned by the control unit 22 is not limited in any way. In this example, (01.01) is assigned as the address of the illumination device L2 (see FIG. 22).

[0087] As shown in FIG. 16, the control unit 32 of the mobile terminal Mt may hide the lighting device L2 with an assigned address from the lighting device list on the display unit 31. As a result, only the lighting devices L7 and L11 that belong to the temporary group Gb and have not yet been assigned an address are displayed in the lighting device list.

[0088] As shown in FIG. 17, the above-described steps S4-1 to S6 are repeated. Thereby, the address settings of the lighting devices L7 and L11 are sequentially performed. That is, when the address settings of the lighting devices L7 and L11 are completed by repeating steps S5-1 to S6, as shown in FIG. 18, no lighting device L is displayed in the lighting device list on the display unit 31. Also, by repeating steps S4-1 to S6, the setting of the regular group and the assignment of addresses are completed for the plurality of lighting devices L grouped into the temporary group Ga and the temporary group Gc.

[0089] The control unit 32 of the mobile terminal Mt confirms that the number of lighting devices L without an assigned address is zero and automatically sets a cluster (step S7-1). For example, as shown in FIG. 22, for each of the regular groups G1 to G3, a lighting device L serving as a GM (gateway module) is set. In the illustrated example, the addresses of the lighting devices L1, L5, and L9 set as the GM (gateway module) have the last two digits set to "00". The lighting devices L1, L5, and L9 set as the GM (gateway module) perform wireless communication with the control device Ct, and the lighting devices L1, L5, and L9 perform wireless communication with each other. The lighting devices L of the GM (gateway module) included in the regular groups G1 to G3 perform wireless communication with their respective GM (gateway modules).

[0090] Next, the control unit 22 of the mobile terminal Mt transmits the 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 regular group, address, 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 device Ct receives the setting signal Sg5, the control unit 22 of the control device Ct stores the setting information included in the setting signal Sg5 in the storage unit 23. Then, the setting signal Sg5 is transmitted to all the lighting devices L (step S7-3). When the wireless communication unit 14 of the plurality of lighting devices L receives the setting signal Sg5, the control unit 12 of the plurality of lighting devices L stores the setting information included in the setting signal Sg5 in the storage unit 13 (step S7-4). Thereby, the setting operation of grouping the plurality of lighting devices L into a regular group and assigning an address is completed. After this, for example, by appropriately transmitting a lighting control signal from the control device Ct to the plurality of lighting devices L, lighting control of the plurality of lighting devices L is performed.

[0092] FIG. 19 shows a setting procedure that can additionally be performed in the above-described lighting control method. In step S11, the setter inputs property information using a WEB app or the like. Next, in step S12, a plurality of 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, visually by the setter. If the number of the confirmed plurality of lighting devices L is correct (step S14: Yes), the setter performs the above-described regular group and address settings.

[0093] As shown in FIG. 20, in this additional setting procedure, for example, a button for "quantity confirmation" is provided in the lighting device list shown on the display unit 31. When the setter touches the "quantity confirmation" button (step S15), the total number of all the plurality 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 illustrated example, the ratio of the number of lighting devices for which the setting has been completed out of the total number of "lighting device quantity" of the plurality of lighting devices L at the site is displayed as the "progress rate".

[0094] In order to execute the additional setting procedure described above, a program that causes a computer provided in the mobile terminal Mt to perform a step of assigning a normal group and an address selected from a plurality of normal groups G1 to G3 to a lighting device L selected from a plurality of lighting devices L, and a step of displaying, on the display unit, the number of lighting devices L to which an address has not yet been assigned according to a request from the setter may be stored in the storage unit 33.

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

[0096] According to the present embodiment, as shown in FIGS. 7 and 12, in the lighting device list, only the lighting devices L grouped into a temporary group selected from any of the temporary groups Ga to Gc are displayed. Thereby, in the setting work by the setter, it is possible to automatically reduce the number of lighting devices L displayed in the list. Therefore, the burden on the setter can be reduced.

[0097] As shown in step S7-1 of FIG. 17 and FIG. 22, in the lighting control system A1, it is confirmed that the number of lighting devices L to which an address has not been assigned is zero, and a cluster is automatically set. Thereby, it is possible to avoid erroneously setting a cluster while there are still lighting devices L to which an address has not been assigned, and setting errors can be reduced.

[0098] As shown in FIG. 12, in the lighting device list, the type information of a plurality of lighting devices L is displayed. Thereby, the setter can improve the efficiency of setting operations such as selection of the lighting device L, such as "this lighting device is a straight tube type" or "this lighting device is a downlight".

[0099] As shown in FIG. 21, by displaying the number of lighting devices L (or progress rate) for which the address is not set, the progress of the setting work can be easily and surely grasped.

[0100] As shown in FIG. 11, when the number of a plurality of lighting devices L based on the property information is different from the number of a plurality of lighting devices L installed at the site, by displaying the mismatch information on the display unit 31, the setter can automatically grasp the number of a plurality of lighting devices L installed at the site without visually confirming etc.

[0101] As shown in FIG. 16, in the lighting device list, the lighting devices L for which the grouping of the regular group has been completed are made non-displayed. Thereby, the number of displayed lighting devices L can be reduced.

[0102] FIGS. 23 to 26 show other embodiments of the present invention. In these figures, the same or similar elements as those in the above embodiments are denoted by the same reference numerals as those in the above embodiments. Also, the configurations of each part in each modification example and each embodiment can be appropriately combined with each other within a range that does not cause a technical contradiction.

[0103] <Second Embodiment> FIGS. 23 and 24 show a lighting control system according to the second embodiment of the present invention. The lighting control system A2 of the present embodiment employs a setting method for preliminary preparation different from that in the above-described lighting control system A1.

[0104] Execute steps S01-1, S01-2, S02-1, and S02-2 described with reference to FIG. 5. In the lighting control system A2 shown in FIG. 23, a plurality of lighting devices L1, L2, ···, Ln-1, Ln are arranged. The plurality of lighting devices L1, L2, ···, Ln-1 can receive the control command signal Sg02 by the wireless communication unit 14. On the other hand, since the lighting device Ln is far from the control device Ct, it cannot receive the control command signal Sg02 by the wireless communication unit 14.

[0105] In step S02-3 of FIG. 5, the lighting device L lights up in the second lighting state. In the present embodiment, in each of the plurality of lighting devices L, when the wireless communication unit 14 receives the control command signal Sg02, the control unit 12 lights up the light source unit 11 in the second lighting state according to the information of the second lighting state included in the control command signal Sg02. On the other hand, when the wireless communication unit 14 cannot receive the control command signal Sg02, the lighting in the first lighting state continues.

[0106] The reception of the control command signal Sg02 by the wireless communication unit 14 may be determined to be received if the received data can be read without error. However, for example, even if the data regarding the radio wave condition of the control command signal Sg02 (received radio wave intensity or SN ratio) in the wireless communication unit 14 is equal to or greater than a predetermined value, it may be determined to be received. As an example, a value with a margin compared to the lower limit value at which data can be received without error is set as the predetermined value of the received radio wave intensity. In this case, even if the control command signal Sg02 is received without data error, if the received radio wave intensity is below the predetermined value, the lighting state is not changed.

[0107] After the controller Ct transmits the control command signal Sg02, the setter checks the lighting device L that is lit in the first lighting state. In FIG. 23, the lighting device Ln is lit in the first lighting state. The setter adds, for example, the function of a relay unit to the lighting device L (lighting device Ln−1) adjacent to the lighting device Ln. The addition of the function of the relay unit to the lighting device Ln−1 may be performed, for example, by software change by a radio signal from the controller Ct. The lighting device Ln−1 to which the function of the relay unit is added transfers the signal received by the 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 controller Ct is relayed by the lighting device Ln−1 and received by the lighting device Ln. As a result, all the lighting devices L including the lighting device Ln are lit in the second lighting state, and the setter recognizes that the wireless communication environment of all the lighting devices L is in order.

[0108] Also according to this embodiment, the burden on the setter can be reduced. Further, according to this embodiment, when a wireless signal from the controller Ct cannot be received by any of the plurality of lighting devices L, the wireless communication environment can be improved by adding a relay function to another lighting device L. That is, by providing a relay function to a specific lighting device (lighting device Ln−1), the wireless communication environment can be improved without newly performing power supply work such as providing a separate relay unit.

[0109] <Third Embodiment> FIGS. 25 and 26 show a lighting control system and a lighting control method according to the third embodiment of the present invention. In the lighting control system A3 of the present embodiment, based on the distance information between the plurality of lighting devices L and the controller Ct and the mutual distance information of the plurality of lighting devices L, the plurality of lighting devices L are assigned to the lighting devices L in a prepared layout diagram.

[0110] In FIG. 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 intensity (RSSI value) of the received identification signal Sg1 in the storage unit 13 (step S22). The reception intensities stored in the storage unit 13 are stored in order, for example, a predetermined number (for example, 10) from those with higher RSSI values.

[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 intensity (RSSI value) when the setting start signal Sg7 is received in the storage unit 13. Then, each of the plurality of lighting devices L transmits a device information signal Sg8 including the reception intensity (RSSI value) when receiving the identification signal Sg1 from another lighting device L, the reception intensity (RSSI value) when receiving the setting start signal Sg7 from the control device Ct, and the identification information, to the control device Ct (step S25). The control device Ct receives the device information signals Sg8 from the plurality of lighting devices L (step S26).

[0112] Also, the control device Ct receives layout diagram information of the plurality of lighting devices L from the mobile terminal Mt, the cloud CL, etc. (step S27). The layout diagram information includes that 12 lighting devices L are arranged at positions Pa to Pm shown in FIG. 26.

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

[0114] Regarding a specific example of step S28, first, regarding the reception intensity of the identification signal Sg1 from other lighting devices L memorized by each lighting device L, lighting devices L with the top four reception intensities being almost the same are extracted. In the example shown in FIG. 26, the lighting devices L6 and L7 arranged at positions Pf and Pg are extracted. In the lighting device L6, the reception intensities from the lighting devices L2, L5, L7, and L10 are the top four reception intensities and are almost the same. Also, in the lighting device L7, the reception intensities from the lighting devices L3, L6, L8, and L11 are the top four reception intensities and are almost the same.

[0115] Next, the reception intensities of the setting start signals Sg7 of the lighting devices L6 and L7 are compared. The lighting device L6 is closer to the control device Ct than the lighting device L7. For this reason, the reception intensity by the lighting device L6 is stronger than the reception intensity by the lighting device L7. Thereby, it can be specified that the lighting device L6 is located at the position Pf and the lighting device L7 is located at the position Pg.

[0116] Next, lighting devices L with the top three reception intensities being almost the same are extracted. In the example shown in FIG. 26, the lighting devices L2, L3, L5, L8, L10, and L11 arranged 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 the closest to the control device Ct, is the strongest, and it is specified that the lighting device L5 is located at the position Pe. The reception intensity of the lighting device L8, which is the farthest from the control device Ct, is the weakest, and it is specified that the lighting device L8 is located at the position Ph. It is specified that the lighting device L10 with the second-strongest reception intensity is located at the position Pj, and the lighting device L3 with the second-weakest reception intensity is located at the position Pc.

[0117] For the remaining lighting devices L2 and L11, the received intensity from the control device Ct does not change significantly. Therefore, when comparing the received intensity of the identification signal Sg1 from multiple lighting devices L by the lighting device L7, the received intensity from the lighting device L11 is stronger than that from the lighting device L2. As a result, it is specified that the lighting device L11 is located at the position Pk. Also, it is specified that the lighting device L2 is located at the position Pb.

[0118] Next, for the lighting devices L1, L4, L9, and L12, in the order of lighting devices L9, L1, L12, and L4, the received intensity from the control device Ct is stronger. For this reason, it is specified that the lighting device L9 is located at the position Pi, the lighting device L1 is located at the position Pa, the lighting device L12 is located at the position Pm, and the lighting device L4 is located at the position Pd.

[0119] Thus, according to the lighting control system A3, based on the mutual received intensity between multiple lighting devices L, the received intensity between multiple lighting devices L and the control device Ct, and the layout diagram information of multiple lighting devices L, it is possible to automatically identify the layout of multiple lighting devices L. For this reason, it is not necessary for the setter to perform setting operations using the mobile terminal Mt or visually check the lighting states of multiple lighting devices L. Therefore, the burden on the setter can be further reduced. As another method of automatically setting a temporary group, the received intensity (RSSI value) between lighting devices can be relatively processed by two-dimensional mapping, and a temporary group can be set from the average value between the distances of each lighting device 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. The specific configuration of the lighting control system, lighting control method, program, and display method according to the present invention can be freely designed in various ways.
