[0014] Hereinafter, the embodiments will be described in detail with reference to the drawings. Note that the embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component arrangement and connection forms, steps, and order of steps shown in the following embodiments are merely examples and are not intended to limit the present invention. In addition, among the components in the following embodiments, components that are not described in the independent claims will be described as optional components.

[0015] In addition, each drawing is a schematic diagram and is not necessarily a precise illustration. In each drawing, the same reference numerals are used for substantially the same configurations, and duplicated explanations may be omitted or simplified.

[0016] (Embodiment 1) [1. Overview] First, an overview of the lighting system according to the first embodiment will be described.

[0017] The lighting system according to the first embodiment is a system that collectively controls at least some of a plurality of lighting devices based on an instruction to execute scene control input by a user. In the lighting system, control information for scene control includes connection information of a circuit unit (hereinafter also referred to as a circuit unit corresponding to a lighting device) that switches between connection and disconnection of a lighting device to be controlled and a power source. Therefore, in the lighting system, even if the circuit unit corresponding to a lighting device to be controlled is in a disconnected state, the switch can switch the circuit unit to a connected state. As a result, in the lighting system, all lighting devices to be controlled can obtain an instruction to execute scene control, and it becomes possible to cause all lighting devices to be controlled to execute scene control. Note that, hereinafter, when a switch of a lighting device is turned ON, it means that a circuit unit connecting the lighting device to a power source is connected, and when a switch of a lighting device is turned OFF, it means that a circuit unit connecting the lighting device to a power source is disconnected.

[0018] The lighting devices may be arranged inside a building, or may be installed outside the building, for example, on an exterior wall, a pillar, a fence, etc. The building may be, for example, a residence such as an apartment building or a detached house, or may be a facility other than a residence, such as an office.

[0019] The scene control refers to controlling the lighting (dimming and color adjustment) of at least some of the lighting devices to produce scenes in the user's life. The scenes may be various scenes in the user's life, such as life scenes such as getting up, going to bed, returning home, and going out, and work scenes such as a meeting, desk work, a break, and a nap.

[0020] In this embodiment, the controlled device of the scene control is a lighting device, but is not limited to this. For example, the controlled device of the scene control may include an air conditioner, a floor heating device, an electric shutter, an electric lock, an aroma diffuser, or an audio device in addition to the lighting device.

[0021] [2. Configuration] Next, a description will be given of the configuration of the lighting system according to the embodiment 1. Fig. 1 is a block diagram showing an example of the functional configuration of the lighting system according to the embodiment 1.

[0022] 1, the lighting system 100 includes, for example, an information terminal 10, a control device 20, a switch 30, a first lighting device 40a, a second lighting device 40b, and a third lighting device 40c. Each component will be described below.

[0023] [2-1. Information terminal] The information terminal 10 is a terminal device that accepts input from a user and outputs the input to the control device 20. More specifically, the information terminal 10 is a portable terminal device that is operated by a user to input an execution instruction for executing scene control and to input setting information for setting scene control. The information terminal 10 is, for example, a portable terminal such as a smartphone, a tablet terminal, or a PDA (Personal Digital Assistant). The information terminal 10 may also be a dedicated terminal used in the lighting system 100.

[0024] The information terminal 10 includes, for example, a communication unit 11, a control unit 12, a storage unit 13, a reception unit 14, and a presentation unit 15.

[0025] [Communications Department] The communication unit 11 is a communication circuit (communication module) for the information terminal 10 to communicate with the control device 20 via the wide area communication network 5. The communication unit 11 may include a communication circuit (communication module) for communicating via a local communication network. The communication unit 11 is, for example, a wireless communication circuit for performing wireless communication, but may also be a wired communication circuit for performing wired communication. The communication standard for the communication performed by the communication unit 11 is not particularly limited.

[0026] [Control Unit] The control unit 12 is a control circuit that performs information processing for controlling the operation of the information terminal 10. The control unit 12 has a processor and the like, and performs various information processing by the processor executing a program stored in the storage unit 13. The control unit 12 is realized by, for example, a microcomputer, but may also be realized by a processor or a dedicated circuit.

[0027] [Storage] The storage unit 13 is a storage device that stores the control program and the like executed by the control unit 12. The storage unit 13 is realized by, for example, a semiconductor memory.

[0028] [Reception] The reception unit 14 is an input interface that receives operation input by a user. Specifically, the reception unit 14 is realized by a touch panel display or the like. For example, when the reception unit 14 is equipped with a touch panel display, the touch panel display functions as the presentation unit 15 and the reception unit 14. Note that the reception unit 14 is realized by, for example, a touch panel, but may also be realized by a mouse, a keyboard, a hardware button, a microphone, or the like.

[0029] The reception unit 14 may include a speaker (not shown). The speaker outputs a voice (mechanical voice) in response to the speech voice acquired by the microphone, for example. This allows the user to input an instruction to execute scene control in an interactive format.

[0030] [Presentation part] The presentation unit 15 is, for example, a display device that displays image information including characters and symbols. Furthermore, the presentation unit may include an audio output device that outputs audio information. The display device is, for example, a display including a liquid crystal (LC) panel or an organic EL (Electro Luminescence) panel as a display device. The audio output device is, for example, a speaker.

[0031] [2-2.Control device] The control device 20 controls the switches 30 of the multiple lighting devices and the multiple lighting devices. For example, when the control device 20 acquires an execution instruction for scene control output from the information terminal 10, the control device 20 outputs a connection instruction for a circuit unit that switches between connection and disconnection of the lighting devices to be controlled by the scene control and a power source among the multiple circuit units corresponding to the multiple lighting devices included in the switch 30 based on the acquired execution instruction, and outputs an execution instruction for scene control after a predetermined time has elapsed since the output of the connection instruction. Also, for example, when the control device 20 acquires an execution instruction for scene control output from the information terminal 10, the control device 20 outputs a connection instruction for a circuit unit that switches between connection and disconnection of the lighting devices to be controlled by the scene control and a power source among the multiple circuit units corresponding to the multiple lighting devices included in the switch 30 based on the acquired execution instruction, and may output the execution instruction for scene control multiple times within a predetermined time from the output of the connection instruction. More specifically, the control device 20 outputs the execution instruction for scene control multiple times within a predetermined time after outputting the execution instruction for scene control together with the connection instruction for the circuit unit.

[0032] The control device 20 is communicatively connected to, for example, the switch 30, the first lighting device 40a, the second lighting device 40b, and the third lighting device 40c via a local communication network. The control device 20 is also communicatively connected to, for example, the information terminal 10 and a server (not shown) via a wide area communication network 5. In the embodiment, the control device 20 is, for example, a gateway device.

[0033] As shown in FIG. 1, the control device 20 includes, for example, a communication unit 21, a control unit 22, and a storage unit 23.

[0034] [Communications Department] The communication unit 21 includes a communication module (communication circuit) for the control device 20 to communicate with the switch 30, the first lighting device 40a, the second lighting device 40b, and the third lighting device 40c via the local communication network, and a communication module (communication circuit) for communicating with the information terminal 10, a server (not shown), and the like via the wide area communication network 5. The communication unit 21 is, for example, a wireless communication circuit for performing wireless communication, but may also be a wired communication circuit for performing wired communication. The communication standard for communication performed by the communication unit 21 is not particularly limited.

[0035] [Control Unit] The control unit 22 performs various information processing related to the control of the switch 30, the first lighting device 40a, the second lighting device 40b, and the third lighting device 40c. For example, when the control unit 22 acquires an instruction to execute scene control, the control unit 22 reads out control information for scene control from the storage unit 23, and outputs an instruction to connect a circuit unit corresponding to the lighting device to be controlled and an instruction to execute scene control based on the control information. More specifically, the control unit 22 outputs control signals to the switch 30, the first lighting device 40a, the second lighting device 40b, and the third lighting device 40c via the local communication network. The control unit 22 is realized by, for example, a microcomputer, but may also be realized by a processor or a dedicated circuit.

[0036] [Storage] The storage unit 23 is a storage device in which the control program executed by the control unit 22 and the like are stored. The storage unit 23 also stores control information for scene control. The control information for scene control includes control information for connecting a circuit unit corresponding to a lighting device to be controlled. For example, the storage unit 23 also stores a database (not shown) in which identification information of a lighting device to be controlled and identification information of a circuit unit corresponding to the lighting device are associated and registered for the lighting device. Specifically, the storage unit 23 is realized by, for example, a semiconductor memory.

[0037] [2-3. Switch] The switch 30 is a switch for a plurality of lighting devices (in other words, a switch device), and is, for example, a wall switch attached to a wall surface of a building. Here, a description will be given with reference to Fig. 1 and Fig. 2. Fig. 2 is a diagram showing an example of the switch 30 in the first embodiment.

[0038] When the switch 30 receives a connection instruction for the circuit unit output by the control device 20, the switch 30 connects the lighting device and the power source to the circuit unit based on the connection instruction. When the switch 30 does not operate based on the scene control, the switch 30 may be directly operated by a user as a wall switch as shown in Fig. 2. As shown in Fig. 1, the switch 30 includes, for example, a communication unit 31, a control unit 32, a storage unit 33, a reception unit 34, a first circuit unit 35a, a second circuit unit 35b, and a third circuit unit 35c.

[0039] [Communications Department] The communication unit 31 is a communication module (communication circuit) for the switch 30 to communicate with the control device 20, the first lighting device 40a, the second lighting device 40b, and the third lighting device 40c via a local communication network. The communication unit 31 is, for example, a wireless communication circuit for performing wireless communication, but may also be a wired communication circuit for performing wired communication. The communication standard of the communication performed by the communication unit 31 is not particularly limited.

[0040] [Control Unit] The control unit 32 performs signal processing related to the control of the lighting devices that are the control targets of the switch 30 (in other words, the lighting devices under the control of the switch 30). 3 The control unit 32 is realized by, for example, a microcomputer, but may be realized by a processor. When the control unit 32 receives a connection instruction for a circuit unit corresponding to a lighting device to be controlled in the scene control, the control unit 32 controls the circuit unit to connect the lighting device to be controlled and a power source.

[0041] [Storage] The storage unit 33 is a storage device that stores the control program executed by the control unit 32. Specifically, the storage unit 33 is realized by a semiconductor memory or the like.

[0042] [Reception] The reception unit 34 receives operations by a user. The reception unit 34 may include, for example, switch buttons corresponding to each of the multiple circuit units. For example, as shown in FIG. 2, the reception unit 34 may include a first reception unit 34a (in other words, a first switch button), a second reception unit 34b (in other words, a second switch button), and a third reception unit 34c (in other words, a third switch button). The first reception unit 34a receives a switching operation of connecting and disconnecting the first circuit unit 35a. The second reception unit 34b receives a switching operation of connecting and disconnecting the second circuit unit 35b. The third reception unit 34c receives a switching operation of connecting and disconnecting the third circuit unit 35c.

[0043] In the example of Fig. 2, the switch 30 has a switch button like a normal wall switch, but is not limited to this example. The reception unit 34 may have a touch function as an input function and a display function as an output function. In other words, it may be a switch button of an image instead of a mechanical switch button, and is not particularly limited.

[0044] [Circuit section] The circuit section includes a circuit for switching between connection and disconnection between the lighting device controlled by the switch 30 (so-called subordinate lighting device) and a power source. In other words, the circuit is located on a branch circuit (i.e., on a power line) from the building's power system to each lighting device, and turns on and off the electrical connection between the power system and each lighting device. The circuit may be a circuit that structurally opens and closes an electrical contact such as a relay circuit, or may be a semiconductor switching circuit element such as a power transistor. The circuit section includes a first circuit section 35a that switches on and off the power supply to the first lighting device 40a, a second circuit section 35b that switches on and off the power supply to the second lighting device 40b, and a third circuit section 35c that switches on and off the power supply to the third lighting device 40c. Note that the circuit section only needs to include at least one circuit (in other words, a switching circuit). In other words, it is sufficient for the circuit section to directly switch on and off the power supply to at least one device. Note that in this specification, when a circuit is connected or disconnected, it is said that the circuit section is connected or disconnected.

[0045] Also, the circuit section may include, for example, the above-mentioned circuit and a light-emitting element such as an LED (Light Emitting Diode). For example, as shown in Fig. 2, the first circuit section 35a may include a light-emitting element 36a, the second circuit section 35b may include a light-emitting element 36b, and the third circuit section 35c may include a light-emitting element 36c. These light-emitting elements, for example, are turned on when the circuit is disconnected and turned off when the circuit is connected.

[0046] [2-4.Lighting equipment] The lighting devices are lighting devices that are controlled by (i.e., subordinate to) the switch 30. The multiple lighting devices are, for example, a first lighting device 40a, a second lighting device 40b, and a third lighting device 40c. As described above, the lighting devices are installed, for example, inside a building, but may be installed outside the building. The lighting devices are so-called ceiling lights that illuminate a room, but are not particularly limited and may be downlights, pendant lights, spotlights, bracket lights, or the like.

[0047] Specifically, the lighting device includes an LED as a light source. The lighting device may include a fluorescent tube, a semiconductor light emitting element such as a semiconductor laser, or a solid-state light emitting element such as an organic EL (Electro Luminescence) or inorganic EL as a light source.

[0048] Although not shown, the lighting device includes a communication module (communication circuit) for wireless communication with the control device 20 and the switch 30, and receives a control signal transmitted by the communication unit 21 of the control device 20 and the communication unit 31 of the switch 30. That is, the lighting device can acquire a scene control signal output by the control device 20 and turn on or off based on the acquired control signal, and can also turn on or off based on a control signal acquired via the switch 30. For example, if a dimming ratio (dimming level) is specified in the scene control signal, the lighting device emits light at the specified dimming ratio. If a color temperature is specified in the control signal, the lighting device emits light at the specified color temperature. The on and off (on and off) of the power supply from the power system to the lighting device is controlled by a circuit unit of the switch 30.

[0049] [3. Operation] Next, the operation of the lighting system 100 according to the first embodiment will be specifically described with reference to the drawings.

[0050] [First example] Fig. 3 is a sequence diagram showing a first example of the operation of the lighting system 100 according to the embodiment 1. Fig. 4 is a diagram showing an example of a reception screen.

[0051] For example, when the user touches an object displayed on the reception screen (reception unit 14 and presentation unit 15) of information terminal 10, reception unit 14 accepts the instruction indicated by the object. For example, when the user touches a "Scene" button displayed on the touch panel and then touches the "ON" button for scene A, reception unit 14 of information terminal 10 accepts an instruction to execute scene A (S01). Note that reception unit 14 may accept timer reservation of the execution time of scene control. In this case, control device 20 may execute the process of step S03 below at the timer-reserved time.

[0052] The control unit 12 of the information terminal 10 outputs the instruction accepted by the acceptance unit 14 in step S01 to the control device 20 via the communication unit 11 (S02).

[0053] Next, when the control unit 22 of the control device 20 acquires the execution instruction for scene A output by the information terminal 10 in step S02 via the communication unit 21, it reads out control information for scene A from the storage unit 23 (S03). The control information for scene A includes connection control information for connecting a circuit unit that switches between connection and disconnection between the lighting device to be controlled in scene A and a power source, and lighting control information for controlling the lighting state (e.g., dimming rate and color temperature) produced by the lighting device to be controlled in scene A.

[0054] Next, the control unit 22 of the control device 20 outputs a connection instruction for the circuit units (here, the first circuit unit 35a and the second circuit unit 35b) corresponding to the lighting devices to be controlled (here, the first lighting device 40a and the second lighting device 40b) to the switch 30 via the communication unit 21 based on the connection control information of the circuit units for scene A read out from the memory unit 23 in step S03 (S04).

[0055] When the switch 30 acquires the connection instruction output by the control device 20 in step S04, the switch 30 switches the first circuit unit 35a and the second circuit unit 35b to the connection state based on the acquired connection instruction (S05). More specifically, the switch 30 causes the first circuit unit 35a and the second circuit unit 35b to connect the first lighting device 40a and the second lighting device 40b to the power source based on the connection instruction.

[0056] Next, the control device 20 determines whether a predetermined time has elapsed since outputting the connection instruction for the circuit unit in step S04 (S06), and if it determines that the predetermined time has not elapsed (No in S06), the process returns to step S06. On the other hand, if the control device 20 determines that the predetermined time has elapsed (Yes in S06), it outputs an instruction to execute scene A (S07). At this time, the control device 20 outputs the execution instruction to the multiple lighting devices under the switch 30 in a broadcast manner as shown in Fig. 3, but may also output the execution instruction for scene A to the lighting devices to be controlled by scene A (here, the first lighting device 40a and the second lighting device 40b) in a multicast manner.

[0057] Next, the lighting devices to be controlled for scene A (here, the first lighting device 40a and the second lighting device 40b) acquire the execution instruction for scene A output by the control device 20 in step S07, and if the acquired execution instruction is an instruction for themselves, they read out control information for scene A from a memory unit (not shown) (S08).

[0058] Next, the first lighting device 40a and the second lighting device 40b acquire the execution instruction for scene A output by the control device 20 in step S07, and if the acquired execution instruction is an instruction for themselves, they read out control information for scene A from a storage unit (not shown) (S08) and operate according to the control information for scene A. In other words, the first lighting device 40a and the second lighting device 40b execute scene A based on the execution instruction for scene A (S09).

[0059] As described above, when the control device 20 acquires an instruction to execute scene control, it outputs an instruction to supply power to the lighting devices that are the control targets of the scene control (i.e., an instruction to connect the circuit unit) to the switch 30, and outputs an instruction to execute scene control (scene A here) after power is supplied to the lighting devices that are the control targets (i.e., after the power is turned ON). As a result, the lighting system 100 outputs an instruction to execute scene control after power is supplied to all lighting devices that are the control targets of the scene control (here, the first lighting device 40a and the second lighting device 40b), so that all lighting devices that are the control targets can acquire the instruction to execute scene control. Therefore, the lighting system 100 can cause all lighting devices that are the control targets of the scene control to execute scene control.

[0060] [Second example] Next, a second example of the operation of the lighting system 100 according to the first embodiment will be described. Fig. 5 is a sequence diagram showing a second example of the operation of the lighting system 100 according to the first embodiment. In Fig. 5, the same processes as those shown in Fig. 3 are given the same step numbers. In the following, the description of the contents that overlap with the first example will be simplified or omitted.

[0061] In a first example of the operation, when the control device 20 acquires an instruction to execute scene control, it first outputs an instruction to connect the circuit unit to the switch 30, and then, after a predetermined time has elapsed, outputs an instruction to execute scene control to the lighting devices under the switch 30. In a second example of the operation, when the control device 20 acquires an instruction to execute scene control, it outputs an instruction to connect the circuit unit to the switch 30 and also outputs an instruction to execute scene control to the lighting devices under the switch 30, and then outputs the instruction to execute scene control multiple times for a predetermined time. Note that, as in the first example of the operation, the lighting devices to be controlled in scene A are the first lighting device 40a and the second lighting device 40b.

[0062] When the reception unit 14 of the information terminal 10 receives an instruction to execute scene A (S01), the control unit 12 outputs the instruction to the control device 20 via the communication unit 11 (S02).

[0063] Next, when the control unit 22 of the control device 20 acquires the execution instruction for scene A output by the information terminal 10 in step S02 via the communication unit 21, the control unit 22 reads out the control information for scene A from the storage unit 23 (S03).

[0064] Next, the control unit 22 of the control device 20 outputs a connection instruction for the first circuit unit 35a and the second circuit unit 35b to the switch 30 via the communication unit 21 based on the connection control information of the circuit units in scene A (S04), and outputs an execution instruction for scene A to the lighting devices under the switch 30 (S11). In other words, the control unit 22 of the control device 20 simultaneously outputs a connection instruction and an execution instruction to the switch 30 and the lighting devices under the switch 30 via the communication unit 21.

[0065] When the switch 30 acquires the connection instruction output by the control device 20 in step S04, the switch 30 switches the first circuit section 35a and the second circuit section 35b to the connected state based on the acquired connection instruction (S05).

[0066] The control device 20 outputs a connection instruction (step S04) to the control device 30 via the communication unit 21 within a predetermined time. illumination An instruction to execute scene A is output to the device multiple times (steps S12 to S14).

[0067] Next, the first lighting device 40a and the second lighting device 40b acquire the execution instruction for scene A output by the control device 20 in step S12, and if the acquired execution instruction is an instruction for themselves, they read out control information for scene A from a storage unit (not shown) (S15) and operate according to the control information for scene A. In other words, the first lighting device 40a and the second lighting device 40b execute scene A based on the execution instruction for scene A (S16).

[0068] As described above, when the control device 20 acquires an instruction to execute scene control, it simultaneously outputs an instruction to supply power to the lighting devices that are the control targets of the scene control (i.e., an instruction to connect the circuit unit) and an instruction to execute scene control (here, scene A), and then outputs the instruction to execute scene control multiple times for a predetermined time. In this way, the lighting system 100 can supply power to all lighting devices that are the control targets of the scene control (here, the first lighting device 40a and the second lighting device 40b), and all of the lighting devices that are the control targets can acquire the instruction to execute scene control even if the timing of starting up each lighting device is different. Therefore, the lighting system 100 can cause all lighting devices that are the control targets of the scene control to execute scene control.

[0069] [4. Effects, etc.] As described above, the control device 20 is a control device that controls the switch 30 of multiple lighting devices (here, the first lighting device 40a, the second lighting device 40b, and the third lighting device 40c) and the multiple lighting devices. When the control device 20 acquires an execution instruction for scene control for collectively controlling the first lighting device 40a and the second lighting device 40b among the multiple lighting devices, the control device 20 outputs a connection instruction to the first circuit unit 35a and the second circuit unit 35b among the multiple circuit units (here, the first circuit unit 35a, the second circuit unit 35b, and the third circuit unit 35c) corresponding to the multiple lighting devices provided in the switch 30, which switches between connection and disconnection between the first lighting device 40a and the second lighting device 40b and a power source (not shown) based on the acquired execution instruction, and outputs an execution instruction for scene control after a predetermined time (e.g., 2 seconds) has elapsed since the connection instruction was output.

[0070] The control device 20 outputs an instruction to execute scene control after power is supplied to all lighting devices (here, the first lighting device 40a and the second lighting device 40b) that are targets of scene control, so that all lighting devices that are targets of scene control can receive the instruction to execute scene control. Therefore, the control device 20 can cause all lighting devices that are targets of scene control to execute scene control.

[0071] The control device 20 is a control device that controls the switch 30 of multiple lighting devices (here, a first lighting device 40a, a second lighting device 40b, and a third lighting device 40c) and the multiple lighting devices, and when it acquires an execution instruction for scene control to collectively control the first lighting device 40a and the second lighting device 40b among the multiple lighting devices, based on the acquired execution instruction, outputs a connection instruction to the first circuit unit 35a and the second circuit unit 35b among the multiple circuit units (here, the first circuit unit 35a, the second circuit unit 35b, and the third circuit unit 35c) corresponding to the multiple lighting devices equipped in the switch 30, which switches between connection and disconnection of the first lighting device 40a and the second lighting device 40b and a power source (not shown), and outputs an execution instruction for scene control multiple times within a predetermined time from the output of the connection instruction.

[0072] Such a control device 20 allows all lighting devices (here, the first lighting device 40a and the second lighting device 40b) that are control targets of scene control to receive an instruction to execute scene control even if power is supplied to the lighting devices and the start-up timing of each lighting device is different. Therefore, the control device 20 can cause all lighting devices that are control targets of scene control to execute scene control.

[0073] Also, for example, the lighting system 100 is a lighting system including any one of the control devices 20 described above, a switch 30, and a plurality of lighting devices (e.g., a first lighting device 40a, a second lighting device 40b, and a third lighting device 40c), in which, upon receiving a connection instruction output by the control device 20, the switch 30 causes the first circuit unit 35a and the second circuit unit 35b to connect the first lighting device 40a and the second lighting device 40b to a power source based on the received connection instruction, and the first lighting device 40a and the second lighting device 40b receive an execution instruction for scene control output by the control device 20, and if the received execution instruction is an instruction for themselves, operate based on the execution instruction.

[0074] According to such a lighting system 100, it is possible to cause all lighting devices that are targets of scene control to execute scene control.

[0075] Furthermore, a lighting control method executed by a computer such as the control device 20 is a lighting control method executed by the control device 20 that controls the switch 30 of multiple lighting devices (e.g., a first lighting device 40a, a second lighting device 40b, a third lighting device 40c) and the multiple lighting devices, and includes: an acquisition step of acquiring an execution instruction for scene control for collectively controlling the first lighting device 40a and the second lighting device 40b among the multiple lighting devices; a first output step of outputting a connection instruction for the first circuit unit 35a and the second circuit unit 35b among multiple circuit units (e.g., the first circuit unit 35a, the second circuit unit 35b, the third circuit unit 35c) corresponding to the multiple lighting devices provided in the switch 30 based on the acquired execution instruction, which switches between connection and disconnection of the first lighting device 40a and the second lighting device 40b to and from a power source; and a second output step of outputting an execution instruction for scene control after a predetermined time has elapsed since the connection instruction was output.

[0076] According to such a lighting control method, an instruction to execute scene control is output after power is supplied to all lighting devices (here, the first lighting device 40a and the second lighting device 40b) that are control targets of scene control, so that all lighting devices that are control targets can receive the instruction to execute scene control. Therefore, according to the lighting control method, it is possible to cause all lighting devices that are control targets of scene control to execute scene control.

[0077] Furthermore, a lighting control method executed by a computer such as the control device 20 is a lighting control method executed by the control device 20 that controls the switch 30 of multiple lighting devices (e.g., a first lighting device 40a, a second lighting device 40b, a third lighting device 40c) and the multiple lighting devices, and includes an acquisition step of acquiring an execution instruction for scene control for collectively controlling the first lighting device 40a and the second lighting device 40b among the multiple lighting devices, and an output step of outputting a connection instruction for the first circuit unit 35a and the second circuit unit 35b, among multiple circuit units (e.g., the first circuit unit 35a, the second circuit unit 35b, the third circuit unit 35c) corresponding to the multiple lighting devices provided in the switch 30, that switches between connection and disconnection of the first lighting device 40a and the second lighting device 40b to a power source based on the acquired execution instruction, and outputting the execution instruction for scene control multiple times within a predetermined time from the output of the connection instruction.

[0078] According to such a lighting control method, power is supplied to all lighting devices (here, the first lighting device 40a and the second lighting device 40b) that are control targets of scene control, and all of the lighting devices that are control targets can receive an instruction to execute scene control even if the start-up timing of each lighting device is different. Therefore, according to the lighting control method, it is possible to cause all of the lighting devices that are control targets of scene control to execute scene control.

[0079] Furthermore, a lighting control method executed by a computer such as the control device 20 is a lighting control method executed by the control device 20 that controls the switch 30 of multiple lighting devices (e.g., a first lighting device 40a, a second lighting device 40b, a third lighting device 40c) and the multiple lighting devices, and includes an acquisition step of acquiring an execution instruction for scene control for collectively controlling the first lighting device 40a and the second lighting device 40b among the multiple lighting devices, and an output step of outputting a connection instruction for the first circuit unit 35a and the second circuit unit 35b, among multiple circuit units (e.g., the first circuit unit 35a, the second circuit unit 35b, the third circuit unit 35c) corresponding to the multiple lighting devices provided in the switch 30, that switches between connection and disconnection of the first lighting device 40a and the second lighting device 40b to a power source based on the acquired execution instruction, and outputting the execution instruction for scene control multiple times within a predetermined time from the output of the connection instruction.

[0080] According to such a lighting control method, power is supplied to all lighting devices (here, the first lighting device 40a and the second lighting device 40b) that are control targets of scene control, and all of the lighting devices that are control targets can receive an instruction to execute scene control even if the start-up timing of each lighting device is different. Therefore, according to the lighting control method, it is possible to cause all of the lighting devices that are control targets of scene control to execute scene control.

[0081] (Embodiment 2) [1. Configuration] Next, the configuration of a lighting system according to the second embodiment will be described.

[0082] In the lighting system 100 according to the first embodiment, the lighting devices to be controlled in the scene control acquire an instruction to execute scene control after power is supplied to the lighting devices. That is, in the first embodiment, the wireless communication circuits included in the multiple lighting devices do not have independent power sources, whereas the lighting system according to the second embodiment differs from the first embodiment in that each of the multiple lighting devices includes a wireless communication circuit having an independent power source. The following description will focus on the differences, and descriptions of overlapping contents will be omitted or simplified. Note that in the second embodiment, the same reference numerals as those in the first embodiment will be used to describe each component.

[0083] As shown in FIG. 1, a lighting system 100 according to embodiment 2 includes, for example, a control device 20, a plurality of lighting devices (here, a first lighting device 40a, a second lighting device 40b, and a third lighting device 40c), and a switch 30 for the plurality of lighting devices.

[0084] [Lighting equipment] Each of the lighting devices includes a wireless communication circuit having an independent power source. The independent power source is, for example, a battery. This allows the lighting devices to communicate wirelessly even when the circuit unit is disconnected and power is not being supplied, because power is supplied to the wireless communication circuit. Therefore, the lighting devices can obtain the scene control execution instruction output by the control device 20 even when the circuit unit is not connected.

[0085] [2. Operation] Next, the operation of the lighting system 100 according to the second embodiment will be specifically described with reference to the drawings.

[0086] [First example] FIG. 6 is a sequence diagram showing a first example of the operation of the lighting system 100 according to the second embodiment.

[0087] When the reception unit 14 of the information terminal 10 receives an instruction to execute scene B (S21), the control unit 12 outputs the instruction to the control device 20 via the communication unit 11 (S22).

[0088] Next, when the control unit 22 of the control device 20 acquires the execution instruction for scene B output by the information terminal 10 in step S22 via the communication unit 21, the control unit 22 reads out the control information for scene B from the storage unit 23 (S23).

[0089] Next, the control unit 22 of the control device 20 outputs a connection instruction for the first circuit unit 35a, the second circuit unit 35b, and the third circuit unit 35c (hereinafter also referred to as the first circuit unit 35a to the third circuit unit 35c) to the switch 30 via the communication unit 21 based on the connection control information of the circuit units in scene B (S24), and outputs an execution instruction for scene B to the lighting devices under the control of the switch 30 (S25). In other words, the control unit 22 of the control device 20 simultaneously outputs a connection instruction and an execution instruction to the switch 30 and the lighting devices under the control of the switch 30 via the communication unit 21.

[0090] When the first lighting device 40a, the second lighting device 40b, and the third lighting device 40c (hereinafter also referred to as the first lighting device 40a to the third lighting device 40c) acquire the instruction to execute scene B output from the control device 20 in step S25 via a wireless communication circuit (not shown), they store the instruction in a memory unit (S26).

[0091] When the switch 30 acquires the connection instruction output by the control device 20 in step S24, it switches the first circuit unit 35a to the third circuit unit 35c to the connection state based on the acquired connection instruction (S27). Even if the first circuit unit 35a to the third circuit unit 35c connect the first lighting device 40a to the third lighting device 40c to the power source, a time lag occurs until each of the first lighting device 40a to the third lighting device 40c is started up.

[0092] The first lighting device 40a to the third lighting device 40c , electric When power is supplied and the device is started, the control information for scene B corresponding to the instruction to execute scene B saved in step S26 is read from a storage unit (not shown) (S28), and scene B is executed (S29).

[0093] As described above, the lighting devices that are the control targets of scene control store the execution instruction for scene control acquired before power supply, and when the lighting devices are started up after power supply, they can read out the control information for scene control from the storage unit based on the instruction acquired before power supply and execute the operation in scene control. In this way, even if power is supplied to all the lighting devices (here, the first lighting device 40a to the third lighting device 40c) that are the control targets of scene control and the start-up timing of each lighting device is different, all the lighting devices that are the control targets can acquire the execution instruction for scene control. Therefore, the lighting system 100 can cause all the lighting devices that are the control targets of scene control to execute scene control.

[0094] [Second example] Next, a second example of the operation of the lighting system 100 according to the second embodiment will be described. Fig. 7 is a sequence diagram showing a second example of the operation of the lighting system 100 according to the second embodiment. In Fig. 7, the same processes as those shown in Fig. 6 are given the same step numbers. In the following, the description of the contents that overlap with the first example will be simplified or omitted.

[0095] In the first example of the operation, the lighting devices acquire an execution instruction for scene control acquired after the circuit unit is switched to the connected state and power is supplied before starting up, and after starting up, reads scene control information from the storage unit based on the execution instruction and executes the operation in scene control. In the second example of the operation, when the lighting devices acquire an execution instruction for scene control and power is not being supplied to themselves, they output a signal to the control device 20 requesting connection of the circuit unit. Note that, as in the first example of the operation, the lighting devices to be controlled in scene B are the first lighting device 40a to the third lighting device 40c.

[0096] When the reception unit 14 of the information terminal 10 receives an instruction to execute scene B (S21), the control unit 12 outputs the instruction to the control device 20 via the communication unit 11 (S22).

[0097] Next, when the control unit 22 of the control device 20 acquires the execution instruction for scene B output by the information terminal 10 in step S22 via the communication unit 21, the control unit 22 reads out the control information for scene B from the storage unit 23 (S23).

[0098] Next, the control unit 22 of the control device 20 outputs an instruction to execute scene B to the lighting devices (here, the first lighting device 40a to the third lighting device 40c) under the control of the switch 30 (S31).

[0099] When the first lighting device 40a to the third lighting device 40c under the switch 30 acquire the instruction to execute scene B output from the control device 20 in step S31 via a wireless communication circuit (not shown), the first lighting device 40a to the third lighting device 40c store the instruction in a memory unit (S32).

[0100] Next, among the lighting devices to be controlled in scene B, a lighting device to which power is not being supplied (for example, the third lighting device 40c) outputs a signal to the switch 30 requesting connection of a circuit unit (here, the third circuit unit 35c) that switches between on and off the supply of power to the lighting device itself (S33).

[0101] When the switch 30 receives the signal output by the third lighting device 40c in step 33, it switches the third circuit section 35c to the connected state (S34).

[0102] Although not shown, when the third lighting device 40c is supplied with power and activated, it outputs a signal indicating the activation to the switch 30. When the switch 30 receives the signal indicating the activation from the third lighting device 40c, it outputs a command to start scene B to the lighting devices to be controlled for scene B (here, the first lighting device 40a to the third lighting device 40c).

[0103] When the first lighting device 40a to the third lighting device 40c receive a command to start scene B from the switch 30, they read out control information for scene B from a storage unit (not shown) (S35) and execute operations for scene B (S36).

[0104] As described above, when a lighting device that is a target of scene control receives an instruction to execute scene control via wireless communication, if power is not being supplied to the lighting device itself, the lighting device outputs a signal to the switch 30 requesting connection of a circuit unit to supply power to the lighting device itself. Therefore, all lighting devices that are target of scene control can execute operations in scene control. Therefore, the lighting system 100 can cause all lighting devices that are target of scene control to execute scene control.

[0105] [Modification 1 of the second example] In the second example of the operation, when there is a lighting device (for example, the third lighting device 40c) to which power is not being supplied among the lighting devices to be controlled in the scene control, the lighting device (the third lighting device 40c) outputs a signal to the switch 30 requesting connection of a circuit unit that switches on and off the supply of power to the lighting device itself. In a first modified example of the second example of the operation, the information terminal 10 of the user is notified that the lighting device to be controlled is not being supplied with power (i.e., the power is turned off), and scene control is performed according to the user's selection. FIG. 8 is a diagram showing an example of a display screen.

[0106] 7, the third lighting device 40c outputs a connection request signal of the third circuit unit 35c to the switch 30, but in Modification 1, the third lighting device 40c may output a signal indicating that power is not being supplied to the third lighting device 40c to the control device 20. Upon receiving the signal output by the third lighting device 40c, the control device 20 may notify the information terminal 10 that power is not being supplied to the third lighting device 40c.

[0107] As shown in FIG. 8, when the information terminal 10 receives the notification output by the control device 20, the display unit 15 displays “The power to the third lighting device 40c is turned OFF,” and an acceptance button is displayed to accept an instruction to turn ON the power to the third lighting device 40c (i.e., to connect the third circuit unit 35c).

[0108] When the user touches the ON button displayed on the presentation unit 15, the reception unit 14 receives an instruction to power on the third lighting device 40c (in other words, an instruction to connect the third circuit unit 35c). Then, the control unit 12 of the information terminal 10 outputs the instruction received by the reception unit 14 to the control device 20, and when the control unit 22 of the control device 20 receives the instruction from the information terminal 10, it outputs an instruction to the switch 30 to connect the third circuit unit 35c.

[0109] As described above, when a circuit unit corresponding to a lighting device that is a target of scene control is not connected (power is not supplied to the lighting device), it may be determined whether or not to supply power to the lighting device in accordance with a user's selection.

[0110] [3. Effects, etc.] As described above, the lighting system 100 is a lighting system including the control device 20, a plurality of lighting devices, and the switch 30 for the plurality of lighting devices, each of which is provided with a wireless communication circuit (not shown in FIG. 1 ) having an independent power source. When the control device 20 receives an execution instruction for scene control (e.g., an execution instruction for scene B) for collectively controlling the first lighting device 40a, the second lighting device 40b, and the third lighting device 40c among the plurality of lighting devices, the control device 20 controls a first circuit unit 30a, 30b, and 40c among the plurality of circuit units provided in the switch 30 to switch between connection and disconnection of the first lighting device 40a, the second lighting device 40b, and the third lighting device 40c to a power source based on the execution instruction received. When the switch 30 acquires the connection instruction output by the control device 20, it causes the first circuit section 35a, the second circuit section 35b and the third circuit section 35c to connect the first lighting device 40a, the second lighting device 40b and the third lighting device 40c to a power source, and the first lighting device 40a, the second lighting device 40b and the third lighting device 40c acquire the execution instruction output by the control device 20 via the wireless communication circuit, and after the first lighting device 40a, the second lighting device 40b and the third lighting device 40c are connected to the power source, they execute operations based on the execution instructions.

[0111] Such a lighting system 100 stores an instruction to execute scene control acquired by a lighting device targeted for scene control before power is supplied, and when started up after power is supplied, it can read out control information for scene control from the storage unit based on the instruction acquired before power is supplied and execute an operation in scene control. As a result, even if power is supplied to all lighting devices targeted for scene control (here, the first lighting device 40a to the third lighting device 40c) and the start-up timing of each lighting device is different, all lighting devices targeted for scene control can acquire an instruction to execute scene control. Therefore, the lighting system 100 can cause all lighting devices targeted for scene control to execute scene control.
