The first control unit 12 generates or selects operation information based on the operation of the operation unit 11, for example. Further, the first control unit 12 may generate or select control information based on the operation of the operation unit 11. The first control unit 12 controls the first wireless communication unit 14 to transmit operation information and control information by wireless communication. Alternatively, when a specific operation is performed on the operation unit 11, the emergency mode information may be transmitted from the first wireless communication unit 14.

To illustrate the function of the first wireless communication unit 14, for example, it transmits a control signal, operation information, or emergency mode information to the first cluster Cn1 or any one of the plurality of lighting devices L.

Wireless communication by the first wireless communication unit 14 is not limited in any way, and in this embodiment, it will be described as wireless communication using a specific protocol. The communication frequency of wireless communication using a specific protocol is not limited at all, and examples include a 920 MHz band, a 2.4 GHz band, a 5 GHz band, and the like. Further, specific examples of the first protocol are not particularly limited, and include, for example, Bluetooth (registered trademark) including BLE (Bluetooth Low Energy), Zigbee (registered trademark), Wi-Fi (registered trademark), or a proprietary standard protocol. is exemplified.

In this embodiment, the operating device Od constructs the first cluster Cn1, which is the mesh network shown in FIG. 1, using a unique protocol using, for example, first radio waves in the 2.4 GHz band.

The first power supply unit 15 is for supplying power necessary for operation to the first control unit 12, the first wireless communication unit 14, and the like. The first power supply section 15 has, for example, a function as an AC/DC converter that converts commercial AC 100V or 200V power into DC power, a transformer function, and the like.

Next, an example of the operation of the lighting system A1 will be described below with reference to FIGS. 6 to 9.

Lighting system A1 has a normal mode and an emergency mode. In the normal mode, as shown in FIG. 6, when a user performs an operation on the operation unit 11 of the operation device Od, operation information corresponding to the operation is generated or selected (step S1).

FIG. 9 is a flowchart showing the information generation and selection process of the first control unit 12, and a part thereof includes step S1. The first control unit 12 is in a standby state, for example, until the operation unit 11 is operated (step S121: No). When the operation unit 11 is operated (step S121: Yes), the first control unit 12 determines whether the current mode is the normal mode. If the current mode is the normal mode (step S122: Yes), the first control unit 12 refers to the operation information table stored in the first storage unit 13, for example (step S123). Then, the first control unit 12 generates operation information corresponding to the operation content using the operation information table, or selects corresponding operation information from the operation information table (step S124). The operation information is, for example, digital information set corresponding to each operation on the operation unit 11.

Next, the first control unit 12 causes the first wireless communication unit 14 to transmit the generated or selected operation information (step S2). In this embodiment, the first wireless communication unit 14 transmits operation information to the first cluster Cn1 using a specific protocol. Alternatively, if the operating device Od does not belong to the first cluster Cn1, the first wireless communication unit 14 transmits the operating information to any one of the plurality of lighting devices L by wireless communication.

Upon receiving the operation information, one of the plurality of lighting devices L (in the illustrated example, lighting device L1) generates data that can be transferred in the first cluster Cn1 as necessary, and transmits the data to the adjacent lighting device. Transfer to L. As a result, the operation information is transferred within the first cluster Cn1 (step S3).

When the third wireless communication unit 34 of the control device Ct receives the operation information transferred from the first cluster Cn1, the operation information is transmitted from the third wireless communication unit 34 to the third control unit 32. The information is stored in the storage unit 33 as appropriate. The third control unit 32 generates or selects control information based on the operation information (step S4). The third control unit 32 generates control information by reading information corresponding to the operation information from a control information table stored in the third storage unit 33, or generates control information corresponding to the operation information from the control information table. Select information. The control information is information for setting the light source section 21 of the lighting device L to a state corresponding to the operation information, and is, for example, digital information including a current value and duty ratio uniquely set to the light source section 21.

Next, the third control unit 32 transmits the generated or selected control information from the third wireless communication unit 34 to the first cluster Cn1 (step S5). The second control unit 22 of the plurality of lighting devices L in the first cluster Cn1 checks whether the control information received by the second wireless communication unit 24 includes the identification ID of the lighting device itself. When the control information includes the identification ID of the device itself, the second control section 22 appropriately controls the lighting state of the light source section 21 and the like according to the control information. Further, the second control unit 22 transfers the control information from the second wireless communication unit 24 to the first cluster Cn1 (adjacent lighting device L) (step S6). When the transfer of the control information within the first cluster Cn1 is completed, the lighting control of the plurality of lighting devices L corresponding to the operation on the operation unit 11 of the operation device Od is completed.

Next, the operation in emergency mode will be explained. The emergency mode is a mode when the control device Ct is not functioning normally for some reason. For example, when the user recognizes that the control device Ct is not functioning normally, the user performs a specific operation on the operation section 11 of the operation device Od, and turns on the emergency mode flag in response. A process (step S11) is performed.

FIG. 8 is a flowchart showing the first state flag switching process corresponding to step S11. The first control unit 12 is in a standby state, for example, until a specific operation is performed on the operation unit 11 (step S111: No). When a specific operation is performed on the operation unit 11 (step S111: Yes), the first control unit 12 determines whether the current mode is the normal mode. If the current mode is the normal mode (step S112: Yes), the first control unit 12 sets the emergency mode flag to ON (step S113). On the other hand, if the current mode is not the normal mode, that is, if it is the emergency mode (step S112: No), the first control unit 12 maintains the emergency mode flag as it is.

Next, the first control unit 12 generates or selects control information based on the operation details (step S12). In FIG. 9, when the operation unit 11 is operated (step S121: Yes), the first control unit 12 determines whether the current mode is the normal mode. When the current mode is the emergency mode, that is, when it is not the normal mode (step S122: No), the first control unit 12 refers to the control information table stored in the first storage unit 13, for example (step S125). Next, the first control unit 12 generates control information corresponding to the operation content using the control information table, or selects corresponding control information from the control information table (step S126). The control information is information for setting the light source section 21 of the lighting device L to a state corresponding to the operation information, and is, for example, digital information including a current value and duty ratio uniquely set to the light source section 21.

Next, the first control unit 12 transmits the generated or selected control information from the first wireless communication unit 14 to the first cluster Cn1 (or directly to any of the plurality of lighting devices L) (step S13). The second control unit 22 of the plurality of lighting devices L in the first cluster Cn1 checks whether the control information received by the second wireless communication unit 24 includes the identification ID of the lighting device itself. When the control information includes the identification ID of the device itself, the second control section 22 appropriately controls the lighting state of the light source section 21 and the like according to the control information. Further, the second control unit 22 transfers the control information from the second wireless communication unit 24 to the first cluster Cn1 (adjacent lighting device L) (step S14). When the transfer of the control information within the first cluster Cn1 is completed, the lighting control of the plurality of lighting devices L corresponding to the operation on the operation unit 11 of the operation device Od is completed.

Next, the functions of the lighting system A1, the operating device Od, and the lighting device L will be explained.

According to this embodiment, even if the control device Ct does not function normally due to a failure or the like, operation control of the plurality of lighting devices L can be continued more reliably by operating in the emergency mode.

Further, when the user realizes that the control device Ct is not functioning normally by the operation device Od executing the first status flag switching process (step S11) shown in FIGS. 7 and 8, The lighting system A1 can be operated and controlled in emergency mode more easily without delay.

10-19 illustrate other examples or embodiments of the invention. In addition, in these figures, the same or similar elements as in the above embodiment are given the same reference numerals as in the above embodiment. Furthermore, the configurations of each part in each modification and each embodiment can be combined with each other as appropriate within a range that does not cause technical contradiction.

10 to 12 show other examples of emergency modes. As shown in FIG. 10, when the user recognizes that the control device Ct is not functioning normally, the user performs a specific operation on the operation section 11 of the operation device Od, and the first control section 12 turns on the emergency mode flag in response to this (step S21). Next, the first control unit 12 causes the emergency mode information to be transmitted from the first storage unit 13 to the first cluster Cn1 (step S22). The plurality of lighting devices L constituting the first cluster Cn1 store the emergency mode information received by the second wireless communication unit 24 in the second storage unit 23, for example. Further, the emergency mode information is transferred from the second wireless communication unit 24 to the neighboring lighting device L to transfer the information within the first cluster Cn1 (step S23).

FIG. 11 shows the second state flag switching process (step S23) in the lighting device L that has received the emergency mode information. This process is in a standby state until the emergency mode information is received (step S231: No). Upon receiving the emergency mode information (step S231: Yes), the second control unit 22 determines whether the current mode is the normal mode. If the current mode is the normal mode (step S232: Yes), the second control unit 22 sets the emergency mode flag to ON (step S233). On the other hand, if the current mode is not the normal mode, that is, if it is the emergency mode (step S232: No), the second control unit 22 maintains the emergency mode flag as it is.

As shown in FIG. 10, when the user performs an operation on the operation unit 11 of the operation device Od, operation information corresponding to the operation is generated or selected (step S24). This step is the same process as step S1 described above.

FIG. 9 is a flowchart showing the information generation and selection process of the first control unit 12, and a part thereof includes step S1. The first control unit 12 is in a standby state, for example, until the operation unit 11 is operated (step S121: No). When the operation unit 11 is operated (step S121: Yes), the first control unit 12 determines whether the current mode is the normal mode. If the current mode is the normal mode (step S122: Yes), the first control unit 12 refers to the operation information table stored in the first storage unit 13, for example (step S123). Then, the first control unit 12 generates operation information corresponding to the operation content using the operation information table, or selects corresponding operation information from the operation information table (step S124). The operation information is, for example, digital information set corresponding to each operation on the operation unit 11.

In this example, the plurality of lighting devices L include a first lighting device and a second lighting device. Here, an example will be described in which the lighting device L1 is the first lighting device and the lighting devices L2 to Ln are the second lighting devices.

In L1, which is the first lighting device, when the second wireless communication unit 24 receives the operation information, the information generation and selection process shown in FIG. 12 is performed. A part of this process corresponds to step S3 described above, and another part corresponds to step S26 in FIG. 10. In this process, the second wireless communication unit 24 is in a standby state until it receives the operation information (step S261: No). When the second wireless communication unit 24 receives the operation information (step S261: Yes), the second control unit 22 determines whether the current mode is the normal mode. If the current mode is the normal mode (step S262: Yes), the second control unit 22 transfers the received operation information from the second wireless communication unit 24 to the other lighting device L (first cluster Cn1). (Step S263).
