[0012] (Embodiment) [Configuration] First, the configuration of a lighting system according to an embodiment will be described. Fig. 1 is a block diagram showing the functional configuration of a lighting system according to an embodiment. Fig. 2 is a diagram showing an example of a space to which the lighting system according to an embodiment is applied.

[0013] The lighting system 10 is a system that can brightly illuminate a space 90 using a plurality of lighting devices 20 installed therein. The lighting system 10 is also a system that can notify a user of lighting devices 20 for which an update has failed when updating the software of the plurality of lighting devices 20. The lighting system 10 can also check the software versions of the plurality of lighting devices 20 at any time other than during an update (during operation), and notify a user of lighting devices 20 for which the installed software is not a predetermined version. The space 90 is, for example, an office space, but may also be a space in a factory or a space in a medical institution, and there is no particular limitation on the type of space the space 90 is.

[0014] 1 , lighting system 10 includes a plurality of lighting devices 20, a data transmission device 30, a lighting control device 40, and a server device 50. The plurality of lighting devices 20, the data transmission device 30, and the lighting control device 40 form a wireless mesh network. The wireless mesh network may also include relay devices (communication nodes without lighting functions) not shown.

[0015] It is sufficient that the lighting system 10 includes at least one lighting device 20. The lighting system 10 may also include a plurality of data transmission devices 30, or a plurality of lighting control devices 40.

[0016] The lighting device 20 is a so-called base light that is installed on the ceiling of the space 90 and illuminates the interior space. The specific form of the lighting device 20 is not particularly limited, and the lighting device 20 may be a ceiling light, a downlight, a spotlight, or the like. The lighting device 20 includes a light-emitting unit 21, a wireless communication unit 22, an information processing unit 23, and a storage unit 24.

[0017] The light-emitting unit 21 emits light into the space 90 so that the lighting device 20 can illuminate the space 90. The light-emitting unit 21 is realized by a light-emitting module using an LED as a light-emitting element, and emits, for example, white light. The light-emitting unit 21 may also be realized by a light-emitting module using other light-emitting elements, such as a semiconductor laser, an organic electroluminescence (EL), or an inorganic EL.

[0018] The wireless communication unit 22 is a wireless communication circuit that enables the lighting device 20 to communicate with the data transmission device 30 and the lighting control device 40. The wireless communication unit 22 communicates with the data transmission device 30 and the lighting control device 40 in accordance with a communication standard such as Bluetooth (registered trademark) Mesh.

[0019] The information processing unit 23 controls the light emission state (such as dimming state or color adjustment state) of the light emitting unit 21. The information processing unit 23 is realized by, for example, a microcomputer, but may also be realized by a processor or a dedicated circuit. The functions of the information processing unit 23 are realized by hardware such as a microcomputer or processor constituting the information processing unit 23 executing a computer program (software) stored in the storage unit 24.

[0020] The storage unit 24 is a storage device that stores the computer program executed by the information processing unit 23 (in other words, the software installed in the lighting device 20) and the like. The storage unit 24 is realized by, for example, a semiconductor memory.

[0021] The data transmission device 30 is a device that obtains the latest software from the server device 50 and distributes the obtained latest software to the plurality of lighting devices 20. The data transmission device 30 includes a wireless communication unit 31, a communication unit 32, an information processing unit 33, and a storage unit 34.

[0022] The wireless communication unit 31 is a wireless communication circuit that enables the data transmission device 30 to communicate with the plurality of lighting devices 20 and the lighting control device 40. The wireless communication unit 31 communicates with the plurality of lighting devices 20 and the lighting control device 40 in accordance with a communication standard such as Bluetooth (registered trademark) Mesh.

[0023] The communication unit 32 is a communication circuit that enables the data transmission device 30 to communicate with the server device 50. The communication unit 32 communicates with the server device 50 via a wide area communication network such as the Internet. The communication unit 32 may be a wired communication circuit that performs wired communication, or a wireless communication circuit that performs wireless communication.

[0024] The information processing unit 33 performs information processing for distributing the latest software to the multiple lighting devices 20. The information processing unit 33 is realized, for example, by a microcomputer, but may also be realized by a processor or a dedicated circuit. The information processing unit 33 includes an execution unit 35 as a functional component. The function of the execution unit 35 is realized when hardware such as a microcomputer or processor constituting the information processing unit 33 executes a computer program (software) stored in the storage unit 34.

[0025] The storage unit 34 is a storage device that stores computer programs and the like executed by the information processing unit 33. The storage unit 34 is realized by, for example, a semiconductor memory.

[0026] The lighting control device 40 controls the light emission of the multiple lighting devices 20. Here, light emission control is used in a broad sense and also includes control to stop light emission (i.e., turn off). Light emission control specifically includes on control, off control, dimming control, and color adjustment control. On control and off control can also be considered to be part of dimming control. The lighting control device 40 includes a wireless communication unit 41, an information processing unit 42, and a storage unit 43.

[0027] The wireless communication unit 41 is a wireless communication circuit that enables the lighting control device 40 to communicate with the plurality of lighting devices 20 and the data transmission device 30. The wireless communication unit 41 communicates with the plurality of lighting devices 20 and the data transmission device 30 in accordance with a communication standard such as Bluetooth (registered trademark) Mesh.

[0028] The information processing unit 42 performs information processing for controlling the light emission of the plurality of lighting devices 20. The information processing unit 42 is realized, for example, by a microcomputer, but may also be realized by a processor or a dedicated circuit. The information processing unit 42 includes a control unit 44 as a functional component. The functions of the control unit 44 are realized by hardware such as a microcomputer or processor constituting the information processing unit 42 executing a computer program (software) stored in the storage unit 43.

[0029] The storage unit 43 is a storage device that stores computer programs executed by the information processing unit 42. The storage unit 43 is realized by, for example, a semiconductor memory.

[0030] The server device 50 is a device that provides the data transmission device 30 with the latest software to be installed in the lighting device 20. The server device 50 is, for example, a cloud server that is installed outside a facility including the space 90.

[0031] [Operation Example 1] During operation of the lighting system 10, software installed in the multiple lighting devices 20 is updated as needed. For example, if support for the OSS (Open Source Software) used by the lighting system 10 ends, a software update is performed to switch to a new OSS. Furthermore, if a fatal defect such as a vulnerability is found in the existing software, an update to software that resolves the defect is performed. If a new function is to be installed in the lighting system 10, an update to software that includes the new function is performed.

[0032] The software is distributed to the plurality of lighting devices 20, for example, using an over-the-air (OTA) function based on wireless communication between the data transmission device 30 and the plurality of lighting devices 20. However, because the transmission and reception of software (actual data of the software) via wireless communication is unstable, there are cases where the software distribution fails to some of the plurality of lighting devices 20. In other words, there are cases where the software update fails to some of the plurality of lighting devices 20.

[0033] Generally, in order to identify a lighting device 20 for which a software update has failed, the user must manually check the software installed on each of the lighting devices 20. When there are a large number of lighting devices 20, it becomes a problem that it takes time to identify the lighting device 20 for which a software update has failed.

[0034] Therefore, when updating the software of a plurality of lighting devices 20 installed in the space 90, the lighting system 10 controls the light emission of the lighting devices 20 that have failed to be updated in a different manner from that of the lighting devices 20 that have successfully been updated, thereby notifying the user of the lighting devices 20 that have failed to be updated. An operation example 1 of such a lighting system 10 will be described below. Fig. 3 is a sequence diagram of the operation example 1 of the lighting system 10.

[0035] When new software for the lighting device 20 becomes available, the server device 50 notifies the data transmission device 30 of this fact. The execution unit 35 of the data transmission device 30 communicates with the server device 50 using the communication unit 32 to obtain the new software (S11).

[0036] The execution unit 35 uses the wireless communication unit 31 to transmit a software update request to the plurality of lighting devices 20 (S12). In other words, the execution unit 35 attempts to update the software of the plurality of lighting devices 20 collectively (collectively). The update request is specifically transmitted to the plurality of lighting devices 20 via the wireless mesh network. That is, each of the plurality of lighting devices 20 may receive the update request directly from the data transmission device 30, or may receive it indirectly via another lighting device 20. The update request includes actual data of the new software.

[0037] The information processing unit 23 of a lighting device 20 that has properly received the update request transmits response information to the data transmission device 30 using the wireless communication unit 22 (S13). Specifically, the response information is transmitted to the data transmission device 30 via the wireless mesh network. On the other hand, the information processing unit 23 of a lighting device 20 that has not properly received the update request does not transmit response information.

[0038] In step S13, lighting devices 20 that have properly received the update request may transmit response information (success) to the data transmission device 30, and lighting devices 20 that have not properly received the update request may transmit response information (failure) to the data transmission device 30.

[0039] Furthermore, in step S13, each of the plurality of lighting devices 20 may transmit response information or response information (success) on the condition that it has properly received the update request and has successfully updated to the new software.

[0040] The wireless communication unit 31 of the data transmission device 30 receives the response information. The response information includes identification information of the lighting device 20 that sent the response information. The storage unit 34 of the data transmission device 30 pre-stores (registers) identification information of the multiple lighting devices 20, and the execution unit 35 can determine whether each of the multiple lighting devices 20 has returned response information in response to the update request. The execution unit 35 generates determination result information indicating whether each of the multiple lighting devices 20 has returned response information (S14), and transmits the determination result information to the lighting control device 40 using the wireless communication unit 31 (S15). FIG. 4 is a diagram showing an example of the determination result information. The determination result information can also be considered information indicating the execution result of the first process for updating software installed in the multiple lighting devices 20.

[0041] The wireless communication unit 41 of the lighting control device 40 receives the determination result information. The control unit 44 controls the light emission of the plurality of lighting devices 20 based on the received determination result information (S16). The control unit 44 controls the light emission of the plurality of lighting devices 20 by transmitting a control signal to each of the plurality of lighting devices 20 using the wireless communication unit 41.

[0042] For example, the control unit 44 may cause the lighting devices 20 from which response information has been received by the data transmission device 30 to emit light at a predetermined brightness, and may cause the lighting devices 20 from which response information has not been received by the data transmission device 30 to emit light at a predetermined brightness, and may cause the lighting devices 20 from which response information has been received by the data transmission device 30 to emit light at a predetermined brightness, and may cause the lighting devices 20 from which response information has been received by the data transmission device 30 to emit light at a predetermined brightness. In other words, the control unit 44 uses dimming control to notify the user of the lighting devices 20 from which response information has not been received by the data transmission device 30 (i.e., the lighting devices 20 for which the update failed).

[0043] Furthermore, the control unit 44 may, for example, cause the lighting devices 20 from which response information has been received by the data transmission device 30 to emit light at a first color temperature, and cause the lighting devices 20 from which response information has not been received by the data transmission device 30 to emit light at a second color temperature different from the first color temperature. In other words, the control unit 44 may use color adjustment control to notify the user of the lighting devices 20 from which response information has not been received by the data transmission device 30 (i.e., the lighting devices 20 for which the update has failed).

[0044] Furthermore, the control unit 44 may blink only the lighting devices 20 from which response information has been received by the data transmission device 30 among the plurality of lighting devices 20. The control unit 44 may blink only the lighting devices 20 from which response information has not been received by the data transmission device 30 among the plurality of lighting devices 20.

[0045] Note that the lighting devices 20 that did not transmit the response information may be malfunctioning, and may be unable to perform light emission control by the lighting control device 40. In anticipation of such a case, the control unit 44 may perform light emission control only on the lighting devices 20 that transmitted the response information among the multiple lighting devices 20, thereby making the lighting devices 20 that did not transmit the response information stand out.

[0046] As described above, the lighting system 10 includes an execution unit 35 that performs a first process (e.g., the process of steps S11 to S13) for updating software installed in the plurality of lighting devices 20, and a control unit 44 that controls the light emission of the plurality of lighting devices 20 based on the execution result of the first process. The first process includes a transmission process (e.g., the process of step S12) that transmits new software required for the update to the plurality of lighting devices 20, and the control unit 44 controls the light emission of the plurality of lighting devices 20 based on determination result information indicating the result of the transmission process. Specifically, the control unit 44 controls the light emission of lighting devices 20 that have failed to be updated in a different manner from that of lighting devices 20 that have been successfully updated.

[0047] According to this lighting system 10, the user can easily find out which lighting devices 20 have failed to be updated.

[0048] [Operation Example 2] The lighting system 10 can check the versions of software installed in the lighting devices 20 at any time other than when the software of the lighting devices 20 is updated, and can notify the user of any lighting devices 20 whose software version does not match a predetermined version. A second operation example of such a lighting system 10 will now be described. Fig. 5 is a sequence diagram of the second operation example of the lighting system 10.

[0049] The execution unit 35 of the data transmission device 30 uses the wireless communication unit 31 to transmit a software version request to the plurality of lighting devices 20 (S21). Specifically, the version request is transmitted to the plurality of lighting devices 20 via the wireless mesh network. That is, each of the plurality of lighting devices 20 may receive the version request directly from the data transmission device 30, or may receive it indirectly via another lighting device 20.

[0050] In each of the lighting devices 20, the wireless communication unit 22 receives the version request. The information processing unit 23 checks the version of the software currently installed in the storage unit 24 and transmits version information indicating the checked version to the data transmission device 30 using the wireless communication unit 22 (S22). Specifically, the version information is transmitted to the data transmission device 30 via the wireless mesh network.

[0051] The wireless communication unit 31 of the data transmission device 30 receives the version information. The version information includes identification information of the lighting device 20 that transmitted the version information. Therefore, the execution unit 35 can grasp the version of the software installed in each of the multiple lighting devices 20, and can determine whether a specific version (e.g., the latest version) of software stored (managed) in the storage unit 34 is installed (S23).

[0052] The execution unit 35 generates determination result information indicating whether the software installed in each of the plurality of lighting devices 20 is a predetermined version (S24), and transmits the determination result information to the lighting control device 40 using the wireless communication unit 31 (S25). Fig. 6 is a diagram showing an example of the determination result information. The determination result information can also be considered information indicating the execution result of the second process for checking the versions of the software installed in the plurality of lighting devices 20.

[0053] The wireless communication unit 41 of the lighting control device 40 receives the determination result information. The control unit 44 performs light emission control of the plurality of lighting devices 20 based on the received determination result information (S26). The control unit 44 controls the light emission of the plurality of lighting devices 20 by transmitting a control signal to each of the plurality of lighting devices 20 using the wireless communication unit 41. In the light emission control, it is sufficient that the light emission of lighting devices 20 having a predetermined version of software installed therein is controlled in a different manner from that of lighting devices 20 having software other than the predetermined version installed therein. Specific examples of light emission control have already been described in step S16 of operation example 1, and therefore detailed description thereof will be omitted.

[0054] As described above, the lighting system 10 includes an execution unit 35 that performs a second process (e.g., the process of steps S21 to S22) to check the versions of software installed in the plurality of lighting devices 20, and a control unit 44 that controls the light emission of the plurality of lighting devices 20 based on the results of the second process. The second process includes a process of determining whether the version of software installed in each of the plurality of lighting devices 20 matches a predetermined version (e.g., the process of step S23), and the control unit 44 controls the light emission of the plurality of lighting devices 20 based on determination result information that indicates the result of the determination process. Specifically, the control unit 44 controls the light emission of lighting devices 20 whose installed software version does not match the predetermined version in a different manner from that of lighting devices 20 whose installed software version matches the predetermined version.

[0055] According to this lighting system 10, the user can easily identify the lighting devices 20 that do not have the specified version of software installed.

[0056] [System Configuration Variation 1] Although lighting system 10 includes data transmission device 30 and lighting control device 40 that is separate from data transmission device 30, lighting system 10 may include lighting control device 40 that has the functions of data transmission device 30. In other words, the processing described as being performed by data transmission device 30 may be performed by lighting control device 40. Fig. 7 is a block diagram showing the functional configuration of a lighting system according to such variation 1.

[0057] 7 includes a plurality of lighting devices 20, a lighting control device 40a, and a server device 50. The lighting control device 40a included in the lighting system 10a includes a wireless communication unit 41, an information processing unit 42, a storage unit 43, and a communication unit 46. Differences between the lighting control device 40a and the lighting control device 40 will now be described.

[0058] The information processing unit 42 included in the lighting control device 40a includes, as a functional component, an execution unit 45. The execution unit 45 executes a first process for updating software installed in the lighting device 20, or a second process for checking the version of the software installed in the lighting device 20. In other words, the execution unit 45 executes the same process as the execution unit 35 of the data transmission device 30.

[0059] Furthermore, communication unit 46 included in lighting control device 40a is a communication circuit that enables lighting control device 40a to communicate with server device 50. Communication unit 46 communicates with server device 50 over a wide area communication network such as the Internet, for example. Communication unit 46 may be a wired communication circuit that performs wired communication, or a wireless communication circuit that performs wireless communication.

[0060] Such lighting system 10a can realize the above-described operation examples 1 and 2. In the above-described operation examples 1 and 2, data transmission device 30 and lighting control device 40 may be replaced with lighting control device 40a, respectively, and execution unit 35 and communication unit 32 may be replaced with execution unit 45 and communication unit 46.

[0061] [Second Modification of System Configuration] In lighting system 10, one of the plurality of lighting devices 20 may perform the same processing as lighting control device 40. Fig. 8 is a block diagram showing the functional configuration of such a lighting system according to a second modification.

[0062] 8 includes a plurality of lighting devices 20, a lighting device 20b, and a server device 50. The lighting device 20b included in the lighting system 10b is a lighting device that functions as a master device for the plurality of lighting devices 20. The lighting device 20b includes a light-emitting unit 21, a wireless communication unit 22, an information processing unit 23, and a storage unit 24.

[0063] The information processing unit 23 included in the lighting device 20b includes, as a functional component, a control unit 25. The control unit 25 obtains, from the data transmission device 30, information indicating the execution results of a first process for updating software installed in the lighting device 20 or a second process for checking the version of the software installed in the lighting device 20 (determination result information), and controls the light emission of the lighting device 20b and the plurality of lighting devices 20 based on the obtained information. In other words, the control unit 25 performs the same processing as the control unit 44 of the lighting control device 40.

[0064] Such a lighting system 10b can realize the above-described operation examples 1 and 2. In the above-described operation examples 1 and 2, the lighting control device 40 may be replaced with the lighting device 20b, and the control unit 44 may be replaced with the control unit 25.

[0065] [Other Modifications] In Operation Example 1 or Operation Example 2 of the above-described embodiment, the execution unit 35 of the data transmission device 30 may use the communication unit 32 to transmit the determination result information to an external system. In other words, the communication unit 32 may transmit the determination result information indicating the execution result of the first process or the second process to the external system. The external system is, for example, a server device (not shown), which manages the determination result information and provides it to the user as needed. Specifically, the external system sends an email with the determination result information attached to an information terminal or the like carried by the user. This allows the lighting system 10 to provide the determination result information to the user as data.

[0066] In the above embodiment, it has been described that the plurality of lighting devices 20, the data transmission device 30, and the lighting control device 40 constitute a wireless mesh network, but the plurality of lighting devices 20, the data transmission device 30, and the lighting control device 40 may also constitute a communication network other than a wireless mesh network.
