[0008] 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. Furthermore, among the components in the following embodiments, components that are not described in the independent claims will be described as optional components.

[0009] In addition, each drawing is a schematic diagram and is not necessarily a precise illustration. In addition, in each drawing, the same reference numerals are used for substantially the same configuration, and duplicated explanations may be omitted or simplified.

[0010] (Embodiment) [composition] First, the overall configuration including the performance control system according to the embodiment will be described. Fig. 1 is a block diagram showing the overall configuration including the performance control system according to the embodiment. As shown in Fig. 1, the performance control system 100 is realized by a server 1. Upon receiving a request from an event organizer via an information terminal 4, the performance control system 100 controls performances by lighting devices 2 (here, lighting device 2A and lighting device 2B) belonging to multiple systems (here, system A and system B).

[0011] In the embodiment, the multiple systems have different communication environments from each other. Here, the difference in communication environment among the systems may be caused by, for example, the performance and type of communication equipment such as the wireless router 3 used in each system, or the traffic of wireless communication according to a communication standard such as Wi-Fi (registered trademark) or interference of obstacles with wireless communication.

[0012] In an embodiment, the event is an online yoga class. Also, in an embodiment, the organizer of the event is an instructor who organizes the yoga class. Note that the event may be an event held online other than a yoga class.

[0013] The multiple systems are different residences, and are residences of participants of an event. In the embodiment, the multiple systems, system A and system B, are residences of participants of a yoga class. In the embodiment, each of the multiple systems includes one lighting device 2. Note that each of the multiple systems may include multiple lighting devices 2.

[0014] The lighting device 2 is a so-called ceiling light that is installed on the ceiling of an indoor space such as a house to illuminate the indoor space. More specifically, the lighting device 2 is a ceiling light having a circular shape in a plan view. The lighting device 2 includes a wireless communication unit 21, a light source 22, a first control unit 23, a first storage unit 24, a speaker 25, a second control unit 26, and a second storage unit 27.

[0015] The wireless communication unit 21 is a communication circuit (communication module) for connecting the lighting device 2 to the wide area communication network 5 via the wireless router 3. The wireless communication unit 21 is a communication circuit that performs radio wave communication (short-range wireless communication) in accordance with a communication standard such as Wi-Fi (registered trademark).

[0016] The light source 22 emits white light into the indoor space so that the lighting device 2 illuminates the indoor space. The light source 22 is realized by, for example, an LED (Light Emitting Diode) element, but may be realized by other light emitting elements such as a semiconductor laser or an organic EL (Electro Luminescence) element.

[0017] The first control unit 23 instructs the second control unit 26 to control the light source 22 based on the performance instruction signal Sig2 received by the wireless communication unit 21 from the server 1 via the wide area communication network 5 and the wireless router 3, and plays the sound content stored in the first storage unit 24 using the speaker 25. The first control unit 23 corresponds to a higher-level control unit (master) of the second control unit 26 described below, and performs various controls, such as control related to the wireless communication unit 21, for operating the lighting device 2 according to specifications.

[0018] The first control unit 23 is realized by, for example, a microcomputer. The function of the first control unit 23 is realized by the microcomputer (hardware) constituting the first control unit 23 executing a computer program (software) stored in the first storage unit 24.

[0019] The first storage unit 24 is a storage device that stores a plurality of sound contents, a computer program executed by the first control unit 23, and the like. The first storage unit 24 is realized by, for example, a semiconductor memory, and the like. The first storage unit 24 may be built into the first control unit 23.

[0020] The speaker 25 is used to reproduce sound content and is, for example, a bass reflex type speaker.

[0021] The second control unit 26 controls the brightness (dimming rate) of the light source 22 based on the instruction information output by the first control unit 23. The second control unit 26 is also capable of controlling the color temperature of the light emitted by the light source 22. The second control unit 26 corresponds to a lower control unit (slave) of the first control unit 23, and is a control unit specialized in controlling the light source 22.

[0022] The second control unit 26 is realized, for example, by a microcomputer separate (separate package) from the microcomputer corresponding to the first control unit 23. The function of the second control unit 26 is realized by the microcomputer (hardware) constituting the second control unit 26 executing a computer program (software) stored in the second storage unit 27.

[0023] The second storage unit 27 is a storage device that stores various information necessary for controlling the light emission of the light source 22, a computer program executed by the second control unit 26, and the like. The second storage unit 27 is realized by, for example, a semiconductor memory, etc. The second storage unit 27 may be built into the second control unit 26.

[0024] The wireless router 3 is a wireless communication device used for connecting the lighting devices 2 and the information terminal 4 to the wide area communication network 5. The wireless router 3 performs radio wave communication (short-range wireless communication) with the lighting devices 2 in accordance with a communication standard such as Wi-Fi (registered trademark). In the embodiment, the wireless router 3 used in the facility of the event organizer is referred to as "wireless router 30", the wireless router 3 used in the residence of system A is referred to as "wireless router 3A", and the wireless router 3 used in the residence of system B is referred to as "wireless router 3B".

[0025] The information terminal 4 is a smartphone, a tablet terminal, a personal computer, or the like, and functions as a remote controller for the lighting device 2 by installing a predetermined application program (hereinafter also simply referred to as a predetermined app). In the embodiment, the information terminal 4 whose user is the organizer of the event is referred to as "information terminal 40", the information terminal 4 whose user is a participant of the event in line A is referred to as "information terminal 4A", and the information terminal 4 whose user is a participant of the event in line B is referred to as "information terminal 4B".

[0026] In the embodiment, the information terminal 40 accepts an operation by the event organizer, and transmits a request signal Sig1 to the server 1 in response to the accepted operation. The request signal Sig1 is a signal that instructs each of the lighting devices 2 of the multiple systems to perform a performance.

[0027] Here, the presentation includes at least a light presentation by light emission from the light source 22 of the lighting device 2. In the embodiment, the presentation further includes a sound presentation by sound emitted from the speaker 25 linked to the light presentation. That is, in the embodiment, the lighting device 2 is capable of linked control for linking the light presentation (e.g., light flickering, etc.) with the sound presentation. Specifically, the linked control is a control for changing the dimming rate of the light source 22 in a predetermined pattern and reproducing sound content using the speaker 25. Note that in the linked control, the light emission color of the light source 22 may be changed.

[0028] Fig. 2 is a diagram showing an example of a presentation. In the example shown in Fig. 2, the presentation is a presentation in a yoga class. As shown in Fig. 2, the first presentation in the yoga class (in other words, the presentation in phase 1) includes three presentations: an "introduction" presentation, a "concentration" presentation, and a "relaxation" presentation. In addition, the next presentation in the yoga class (in other words, the presentation in phase 2) includes an "awakening" presentation.

[0029] In the "introduction" performance, the lighting device 2 executes a "darkening" light performance by turning off the light source 22, and then executes a "brightening" light performance by gradually increasing the brightness of the light source 22. Also, in the "introduction" performance, the lighting device 2 executes a sound performance by playing "BGM1" from the speaker 25, and then executes a sound performance by playing "BGM2" from the speaker 25. Here, the "darkening" light performance is linked to the sound performance of "BGM1", and the "brightening" light performance is linked to the sound performance of "BGM2".

[0030] In the "concentration" effect, the lighting device 2 executes a "fluctuation 1" light effect in which the light emitted by the light source 22 fluctuates in a first dimming pattern, and then executes a "fluctuation 2" light effect in which the light emitted by the light source 22 fluctuates in a second dimming pattern. In addition, in the "concentration" effect, the lighting device 2 executes a sound effect in which "BGM3" is played from the speaker 25, and then executes a sound effect in which "BGM4" is played from the speaker 25. Here, the "fluctuation 1" light effect is linked to the "BGM3" sound effect, and the "fluctuation 2" light effect is linked to the "BGM4" sound effect.

[0031] In the "Relaxed" effect, the lighting device 2 executes a "darker" light effect by reducing the brightness of the light source 22. In addition, in the "Relaxed" effect, the lighting device 2 executes a sound effect by playing "BGM5" from the speaker 25. Here, the "darker" light effect is linked to the sound effect of "BGM5."

[0032] In the "awakening" effect, the lighting device 2 executes a "white light change" light effect by turning on the light source 22 in white. Also, in the "awakening" effect, the lighting device 2 executes a sound effect by playing "BGM6" from the speaker 25. Here, the "white light change" light effect is linked to the sound effect of "BGM6".

[0033] Fig. 3 is a diagram showing an example of the change over time in brightness of the light source 22 in a performance. In the example shown in Fig. 3, the change over time in brightness of the light source 22 due to the light performance in phase 1 in Fig. 2 and the change over time in brightness of the light source 22 due to the light performance in phase 2 in Fig. 2 are shown. As shown in Fig. 3, a grace period is provided between the end timing of phase 1 and the start timing of phase 2, that is, between two consecutive phases. The grace period will be briefly described below.

[0034] When the first control unit 23 of the lighting device 2 controls the playback of sound content and the second control unit 26 controls the light emission of the light source 22 as in the embodiment, there is a problem in that the end timing of the playback control of the sound content and the end timing of the light emission control may differ from each other because the first control unit 23 and the second control unit 26 each measure time independently.

[0035] For example, suppose that the second clock used by the second control unit 26 to measure time deviates from the first clock used by the first control unit 23 to measure time by a range of -1.5% to +1.5%. If it is assumed that the length of phase 1 (the length of the period during which sound content playback control and light emission control are scheduled) is three minutes, the end timing of the sound content playback control is exactly when three minutes have elapsed, whereas the end timing of the light emission control may be up to 2.7 seconds (=3 minutes×0.015) earlier than three minutes or up to 2.7 seconds later than three minutes.

[0036] In this case, at the timing when three minutes have passed since the start of phase 1 (more specifically, at the timing when first control unit 23 determines that three minutes have passed since the start of phase 1), the light emission control of phase 1 by second control unit 26 may not have been completed. If the first control unit 23 instructs light emission control of phase 2 at this timing, second control unit 26 will start light emission control of phase 2 in the middle of light emission control of phase 1, and light skipping (sudden change in dimming rate) may occur.

[0037] Therefore, a grace period is provided between the end timing of phase 1 and the start timing of phase 2. As a result, the light emission control of phase 2 starts after the end of the light emission control of phase 1, so that the occurrence of light skipping can be suppressed and the user can be prevented from feeling uncomfortable about the light presentation.

[0038] The server 1 (performance control system 100) is a cloud server, and is located in a place different from the facility of the event organizer and the dwelling units of each system. The server 1 includes a communication unit 11, a processing unit 12, and a storage unit 13. Note that the storage unit 13 does not have to be included in the components of the performance control system 100.

[0039] The communication unit 11 is a communication circuit (communication module) for connecting the server 1 to the wide area communication network 5. The communication unit 11 is capable of communicating with the information terminal 40 via the wide area communication network 5 and the wireless router 30. The communication unit 11 is also capable of communicating with the lighting device 2A via the wide area communication network 5 and the wireless router 3A, and is also capable of communicating with the lighting device 2B via the wide area communication network 5 and the wireless router 3B. In other words, the communication unit 11 communicates with a plurality of systems (system A and system B in this case) each of which is equipped with a lighting device 2.

[0040] The processing unit 12 is realized by, for example, a microcomputer. The functions of the processing unit 12 are realized by the microcomputer (hardware) constituting the processing unit 12 executing a computer program (software) stored in the storage unit 13.

[0041] The processing unit 12 controls each of the lighting devices 2 of the multiple systems to execute a performance including at least a light performance by light emission from the light source 22. Specifically, when the processing unit 12 acquires a request signal Sig1 from the information terminal 40 via the communication unit 11, the processing unit 12 transmits a performance instruction signal Sig2 instructing the start of a performance specified by the acquired request signal Sig1 to each of the multiple systems (system A and system B in this case) via the communication unit 11. Here, it is assumed that the performance instruction signal Sig2 includes data indicating the content of the performance.

[0042] 1, the processing unit 12 transmits a performance instruction signal Sig21 to the lighting device 2A of the system A via the communication unit 11, and also transmits a performance instruction signal Sig22 to the lighting device 2B of the system B via the communication unit 11. Upon receiving the performance instruction signal Sig21, the lighting device 2A executes the performance specified by the received performance instruction signal Sig21. Furthermore, upon receiving the performance instruction signal Sig22, the lighting device 2B executes the performance specified by the received performance instruction signal Sig22.

[0043] Here, the content of the performance specified by the performance instruction signals Sig21 and Sig22 is the same. Furthermore, the processing unit 12 simultaneously transmits the performance instruction signals Sig21 and Sig22 via the communication unit 11. Therefore, if there is no difference between the communication environment of the system A and the communication environment of the system B, the lighting device 2A of the system A and the lighting device 2B of the system B will start the specified performance at approximately the same time. In reality, since there is a difference between the communication environment of the system A and the communication environment of the system B, the processing unit 12 executes the setting process and the instruction process described below.

[0044] The setting process is a process of acquiring a response time from when a predetermined signal is transmitted via the communication unit 11 until a response signal to the predetermined signal is returned for each of the multiple systems, and setting a standby time based on the acquired response time. Here, the response time is a time that can change depending on the communication environment of each system. Therefore, by acquiring the response time of each system, the processing unit 12 can set a standby period according to the difference in the communication environment of each system.

[0045] For example, assume that the response time of system A is α seconds and the response time of system B is β (<α) seconds. In this case, the processing unit 12 sets the standby time of system B with respect to system A to (β-α) seconds.

[0046] The instruction process is a process for adjusting the timing of instructing the start of a performance for each of the multiple systems based on the standby time set in the setting process. As a result, the processing unit 12 transmits the performance instruction signal Sig2 according to the standby time set for each system, rather than simultaneously transmitting the performance instruction signal Sig2 to each system. In the embodiment, in the instruction process, the processing unit 12 delays the timing of instructing the start of a performance for one or more other systems among the multiple systems to match the timing of starting a performance for the system with the longest response time among the multiple systems.

[0047] Fig. 4 is an explanatory diagram of the timing of starting the performance in each system. In the example shown in Fig. 4, the processing unit 12 sets the standby time of each system in the setting process, taking into consideration not only the response time of each system but also the clock error correction time of each system. Here, the clock error correction time is a time for correcting the error between the first clock used by the first control unit 23 and the second clock used by the second control unit 26 in the lighting device 2 of each system, and for synchronizing the playback control of the sound content by the first control unit 23 and the light emission control of the light source 22 by the second control unit 26. The clock error correction time is the same as the grace period already described.

[0048] 4, in the instruction process, the processing unit 12 delays the timing of instructing the start of a performance in the other system B to match the timing of starting a performance in the system A which has the longest response time. Specifically, in the instruction process, the processing unit 12 transmits a performance instruction signal Sig22 for system B via the communication unit 11 at time t3 when a standby time has elapsed from time t0 when the processing unit 12 transmitted a performance instruction signal Sig21 for system A via the communication unit 11.

[0049] As a result, the lighting device 2A of the system A starts the performance at time t2 when the response time of the system A (time from time t0 to time t1) and the clock error correction time of the system A (time from time t1 to time t2) have elapsed from time t0 when the performance instruction signal Sig21 was transmitted. The lighting device 2B of the system B starts the performance at time t2 when the standby time (time from time t0 to time t3), the response time of the system B (time from time t3 to time t4), and the clock error correction time of the system B (time from time t4 to time t2) have elapsed from time t0 when the performance instruction signal Sig21 was transmitted. In this way, the timing at which the lighting device 2A of the system A and the lighting device 2B of the system B start the performance is roughly synchronized by the instruction processing of the processing unit 12.

[0050] The storage unit 13 is a storage device that stores the standby times of the systems set by the processing unit 12 in the setting process, the computer programs executed by the processing unit 12, and the like. The storage unit 13 is realized by, for example, a semiconductor memory, etc. The storage unit 13 may be built into the processing unit 12.

[0051] [Operation] The operation of the server 1 (performance control system 100) according to the embodiment will be described below with reference to Fig. 5. Fig. 5 is a sequence diagram showing an example of the operation of the performance control system 100 according to the embodiment. In the example shown in Fig. 5, the server 1 issues performance instructions to a lighting device 2A of line A and a lighting device 2B of line B.

[0052] First, the event organizer operates the information terminal 40, whereby a request signal Sig1 is transmitted from the information terminal 40 to the server 1. When the processing unit 12 of the server 1 receives the request signal Sig1 via the communication unit 11, the processing unit 12 executes a setting process. Note that the setting process is not executed immediately upon receiving the request signal Sig1, but is executed, for example, at the stage where both the users of line A and line B who are participants of the event have logged in before the start of the event. It is possible to determine whether the users of line A and line B have logged in based on a login signal including a login name and a password transmitted from the information terminal 4A and the information terminal 4B, respectively.

[0053] In the setting process, the processing unit 12 of the server 1 transmits a confirmation signal (a predetermined signal) to the lighting device 2A and the lighting device 2B via the communication unit 11 (S1). Here, the confirmation signal may include a command instructing the receiving destination to return a response signal. In the embodiment, the processing unit 12 executes a process of obtaining permission to remotely control the lighting device 2 from the users of each system before transmitting the confirmation signal. This process is executed, for example, by transmitting a signal inquiring about the permission to each of the information terminals 4A and 4B. Then, the processing unit 12 transmits a confirmation signal to each system after obtaining the permission from the users of each system. The processing unit 12 may transmit a confirmation signal to the users of each system without obtaining the permission.

[0054] Upon receiving the confirmation signal, the lighting device 2A and the lighting device 2B each return a response signal to the server 1 (S2, S3). Here, the communication environments of the systems A and B are different from each other, and the communication environment of the lighting device 2A is slightly worse than that of the lighting device 2B, and it takes time to respond. For this reason, the response of the lighting device 2A is delayed compared to the response of the lighting device 2B.

[0055] When the processing unit 12 of the server 1 receives the response signals from each of the lighting devices 2A and 2B via the communication unit 11, it sets a standby time based on the response time from when the confirmation signal is transmitted until when the response signal is received (S4). Here, since the response time of the system A is slower than the response time of the system B, the processing unit 12 sets the standby time of the system B relative to the system A.

[0056] Then, the processing unit 12 of the server 1 executes the instruction process. Specifically, the processing unit 12 first transmits a performance instruction signal Sig21 to the lighting device 2A via the communication unit 11 (S5). After that, when a standby time has elapsed, the processing unit 12 transmits a performance instruction signal Sig22 to the lighting device 2B via the communication unit 11 (S6).

[0057] Upon receiving the performance instruction signal Sig21, the lighting device 2A starts the performance (S7). Similarly, upon receiving the performance instruction signal Sig22, the lighting device 2B starts the performance (S8). As described above, the timing of transmitting the performance instruction signals Sig21 and Sig22 is adjusted taking into account the difference in the communication environments of system A and system B, so that the timing of starting the performance in each of the lighting device 2A and the lighting device 2B is roughly the same.

[0058] [advantage] The advantages of the performance control system 100 according to the embodiment will be described below with a comparison with a performance control system of a comparative example. The performance control system of the comparative example differs from the performance control system 100 according to the embodiment in that the performance instruction signal Sig2 is sent simultaneously to each system without executing the setting process and the instruction process.

[0059] For example, if the event organizer is an instructor of an online yoga class and the users of each discipline are participants in the yoga class, the instructor may give advice to each participant in accordance with the content of the performance that changes in real time.

[0060] However, in the comparative example, the performance control system transmits the performance instruction signal Sig2 to each system simultaneously without considering the difference in the communication environment of each system, so that in systems with relatively poor communication environments, the performance starts later than the timing expected by the instructor. Here, for example, the instructor considers that the performance has shifted from Phase 1 to Phase 2 and gives advice about Phase 2. In this case, in systems with relatively good communication environments, the performance has shifted to Phase 2, so the participants in those systems do not feel uncomfortable with the instructor's advice. On the other hand, in systems with relatively poor communication environments, the start of the performance is delayed, so the performance of Phase 1 is still being executed, so the participants in those systems feel uncomfortable with the instructor's advice.

[0061] In contrast, in the performance control system 100 according to the embodiment, the processing unit 12 executes the setting process and the instruction process, and adjusts the timing of instructing the start of the performance for each of the multiple systems, taking into account the difference in response time caused by the communication environment of each system, so that the timing of starting the performance for each of the multiple systems can be easily aligned. For example, in the above example, the performance control system 100 according to the embodiment transmits the performance instruction signal Sig2 in advance to the system with a long response time, i.e., a relatively poor communication environment, and transmits the performance instruction signal Sig2 to the system with a relatively good communication environment after the waiting time has elapsed. Therefore, the timing of starting the performance for each system is roughly aligned, so that participants in each system can receive the instructor's advice under the same performance, and do not feel uncomfortable with the instructor's advice.

[0062] (Modification) Although the embodiment has been described above, the present invention is not limited to the above embodiment.

[0063] In the above embodiment, the processing unit 12 may transmit data indicating the content of the performance to each of the multiple systems via the communication unit 11 before instructing each of the multiple systems to start a performance. For example, in the example shown in Fig. 4, the processing unit 12 may transmit data indicating the content of the performance to systems A and B before transmitting a performance instruction signal Sig21 to system A via the communication unit 11. This aspect has the advantage of being able to reduce the communication load compared to the case where the data is transmitted to each system at the start of a performance.

[0064] Furthermore, in the above embodiment, the processing unit 12 may transmit data indicating the content of the next performance to each of the multiple systems via the communication unit 11 while each of the lighting devices 2 of the multiple systems is performing a performance. For example, in the example shown in Fig. 2, the processing unit 12 may transmit data indicating the content of the performance of Phase 2 to each system via the communication unit 11 while each of the lighting devices 2 of the multiple systems is performing a performance of Phase 1. This aspect has the advantage of being able to reduce the communication load compared to the case where the data is transmitted to each system at the start of the next performance.

[0065] In the above embodiment, the processing unit 12 may execute the setting process again while each of the lighting devices 2 of the multiple systems is performing a performance. Then, in the next instruction process, the processing unit 12 may adjust the timing of instructing the start of the performance for each of the multiple systems based on the waiting time set in the re-setting process. For example, in the example shown in FIG. 2, the processing unit 12 executes the setting process again while the lighting devices 2 of each system are performing the performance of phase 1. Then, in the instruction process for the performance of phase 2, the processing unit 12 adjusts the timing of instructing the start of the performance of each system based on the waiting time set in the re-setting process. In this aspect, even if the communication environment changes while the lighting devices 2 of each system are performing a performance, the timing of instructing the start of the performance is adjusted based on the updated waiting time, so that it is easy to align the timing of starting the next performance for each system.

[0066] In the above embodiment, the server 1 (performance control system 100) transmits the performance instruction signal Sig2 to each system according to the standby time, but this is not limited to the above. For example, the server 1 may transmit the performance instruction signal Sig2 including the standby time to each system simultaneously. Then, the lighting device 2 of each system may execute the performance after waiting for the standby time included in the performance instruction signal Sig2 after receiving the performance instruction signal Sig2.

[0067] In the above embodiment, the processing unit 12 sets the standby time of each system in the setting process by considering not only the response time of each system but also the clock error correction time, but this is not limited to the above. For example, if the error between the first clock used by the first control unit 23 and the second clock used by the second control unit 26 in each system is small enough to be ignored, the processing unit 12 may set the standby time of each system by considering only the response time of each system. Similarly, for example, when the lighting device 2 only performs light performance, the processing unit 12 may set the standby time of each system by considering only the response time of each system.

[0068] For example, the aspect of the lighting device described in the above embodiment is merely an example, and the aspect of the lighting device is not particularly limited. The lighting device may be a base light, a downlight, a spotlight, or the like. In addition, the lighting device may not include a speaker.

[0069] In the above embodiment, the processes executed by a specific processing unit may be executed by another processing unit. The order of multiple processes may be changed, or multiple processes may be executed in parallel.

[0070] In the above embodiment, each component may be realized by executing a software program suitable for each component. Each component may be realized by a program execution unit such as a CPU or a processor reading and executing a software program recorded on a recording medium such as a hard disk or a semiconductor memory.

[0071] Furthermore, each component may be realized by hardware. For example, each component may be a circuit (or an integrated circuit). These circuits may form a single circuit as a whole, or each may be a separate circuit. Furthermore, each of these circuits may be a general-purpose circuit, or a dedicated circuit.

[0072] Furthermore, the general or specific aspects of the present invention may be realized as a system, an apparatus, a method, an integrated circuit, a computer program, or a computer-readable recording medium such as a CD-ROM, or may be realized as any combination of a system, an apparatus, a method, an integrated circuit, a computer program, and a recording medium.

[0073] For example, the present invention may be realized as a method executed by a performance control system, as a program for causing a performance control system to execute the method, or as a computer-readable non-transitory recording medium having such a program recorded thereon. Such a program includes an upgrade program for causing an existing performance control system to operate in the same manner as the performance control system of the above embodiment.

[0074] In addition, the present invention also includes forms obtained by applying various modifications to each embodiment that a person skilled in the art may think of, or forms realized by arbitrarily combining the components and functions of each embodiment within the scope that does not deviate from the spirit of the present invention.

[0075] (summary) As described above, the performance control system 100 according to the first embodiment includes a communication unit 11 and a processing unit 12. The communication unit 11 communicates with a plurality of systems each equipped with a lighting device 2 having a light source 22. The processing unit 12 controls each of the lighting devices 2 of the plurality of systems to execute a performance including at least a light performance by light emission of the light source 22. The processing unit 12 executes a setting process and an instruction process. In the setting process, for each of the plurality of systems, a response time from when a predetermined signal (confirmation signal) is transmitted via the communication unit 11 until a response signal to the predetermined signal is returned is acquired, and a standby time is set based on the acquired response time. In the instruction process, for each of the plurality of systems, the timing of instructing the start of a performance is adjusted based on the standby time set in the setting process.

[0076] According to such a performance control system 100, the timing of issuing the command to start a performance for each of the multiple systems is adjusted taking into account the difference in response time that arises due to the communication environment of each system, which has the advantage that it is easier to align the timing of starting a performance for each of the multiple systems.

[0077] Also, for example, in the performance control system 100 according to the second aspect, in the first aspect, the processing unit 12, in the instruction processing, delays the timing of instructing the start of performance in one or more other systems among the multiple systems to match the timing of starting performance in the system having the longest response time among the multiple systems.

[0078] According to such a performance control system 100, the timing of issuing the command to start a performance for each of the multiple systems is adjusted so as to limit the response time to the system with the longest response time due to the communication environment, which has the advantage that it is easier to align the timing of starting a performance for each of the multiple systems.

[0079] Also, for example, in the performance control system 100 according to the third aspect, in the first or second aspect, the lighting device 2 further includes a speaker 25. The performance further includes a sound performance by a sound emitted from the speaker 25 linked to the light performance.

[0080] According to such a performance control system 100, light and sound performances that are linked to each other are executed, which has the advantage that it is easier to execute a variety of performances compared to when only light performances are executed.

[0081] Also, for example, in the performance control system 100 according to the fourth aspect, in any one of the first to third aspects, the processing unit 12 transmits data indicating the content of the performance to each of the multiple systems via the communication unit 11 before instructing each of the multiple systems to start the performance.

[0082] According to such a performance control system 100, data indicating the content of the performance is transmitted to each of the multiple systems before the performance begins, which has the advantage of reducing the communication load compared to when the data is transmitted to each of the multiple systems at the start of the performance.

[0083] Also, for example, in the performance control system 100 according to the fifth aspect, in any one of the first to fourth aspects, the processing unit 12 transmits data indicating the content of the next performance to each of the multiple systems via the communication unit 11 while each of the lighting devices 2 of the multiple systems is performing a performance.

[0084] According to such a performance control system 100, data indicating the contents of the next performance is transmitted to each of the multiple systems before the lighting device 2 executes the next performance, which has the advantage of reducing the communication load compared to the case where the data is transmitted to each of the multiple systems at the start of the next performance.

[0085] Also, for example, in the performance control system 100 according to the sixth aspect, in any one of the first to fifth aspects, the processing unit 12 executes the setting process again while each of the lighting devices 2 of the multiple systems is performing a performance, and in the next instruction process, adjusts the timing of instructing the start of the performance for each of the multiple systems based on the waiting time set in the re-setting process.

[0086] According to such a performance control system 100, even if the communication environment changes while the lighting devices 2 are performing a performance in each of the multiple systems, the timing of issuing a command to start the performance is adjusted based on the updated standby time, which has the advantage of making it easier to align the timing of starting the next performance in each of the multiple systems.
