[0010] 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 placement and connection forms, steps, and step order 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 not recited in independent claims will be described as optional components.

[0011] It should be noted that the drawings are schematic diagrams and are not necessarily strict illustrations. In addition, in the drawings, substantially the same components are denoted by the same reference numerals, and overlapping descriptions may be omitted or simplified.

[0012] (Embodiment) [composition] 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. As shown in Fig. 1, a lighting system 10 includes a lighting device 20, a wireless router 30, a remote controller 40, an information terminal 50, an information processing server 60, and a video distribution server 70. Note that the lighting system 10 may include multiple lighting devices 20.

[0013] The lighting device 20 is a so-called ceiling light that is installed on the ceiling of an indoor space to illuminate the indoor space. The lighting device 20 is a ceiling light that is circular in plan view, but may be a ceiling light of other shapes. The lighting device 20 may also be a base light, a down light, a spot light, or the like. The lighting device 20 includes a first wireless communication unit 21, a second wireless communication unit 22, a light-emitting unit 23, a lighting control unit 24, and a storage unit 25.

[0014] The first wireless communication unit 21 is a communication circuit (communication module) for the lighting device 20 to perform wireless communication with the remote controller 40. The first 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 BLE (Bluetooth (registered trademark) Low Energy). When the remote controller 40 performs infrared communication instead of radio wave communication, the first wireless communication unit 21 is an infrared light receiving circuit or the like.

[0015] The second wireless communication unit 22 is a communication circuit (communication module) for connecting the lighting device 20 to the wide area communication network 80 via the wireless router 30. The second wireless communication unit 22 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-emitting unit 23 emits white light into the indoor space so that the lighting device 20 can illuminate the indoor space. The light-emitting module of the light-emitting unit 23 includes a first light-emitting element that emits light at a first color temperature (e.g., 5000 K) and a second light-emitting element that emits light at a second color temperature (e.g., 2700 K), and the brightness of the first light-emitting element and the second light-emitting element can be changed independently by the lighting control unit 24. In other words, the light-emitting unit 23 is capable of adjusting the light intensity and color.

[0017] Each of the first light-emitting element and the second light-emitting element is realized by, for example, an LED (Light Emitting Diode) element, but may also be realized by other light-emitting elements such as a semiconductor laser, an organic EL (Electro Luminescence), or an inorganic EL.

[0018] The lighting control unit 24 controls the lighting state of the lighting device 20 (the light-emitting state of at least one of the multiple light-emitting units 23) based on a control signal received by the first wireless communication unit 21 from the remote controller 40 or a control signal received by the second wireless communication unit 22 from the information terminal 50. The lighting state refers to the brightness and color temperature at which the lighting device 20 emits light, or whether the lighting device 20 is turned off. The lighting control unit 24 is realized by, for example, a microcomputer, but may also be realized by a processor or a dedicated circuit. The functions of the lighting control unit 24 are realized when hardware such as the microcomputer or processor constituting the lighting control unit 24 executes a computer program (software) stored in the storage unit 25.

[0019] The storage unit 25 is a storage device that stores light emission pattern information (described later) and computer programs executed by the illumination control unit 24. The storage unit 25 is realized by, for example, a semiconductor memory.

[0020] The wireless router 30 is a wireless communication device used for connecting the lighting devices 20 to the wide area communication network 80. The wireless router 30 performs radio wave communication (short-range wireless communication) with the lighting devices 20 in accordance with a communication standard such as Wi-Fi (registered trademark).

[0021] The remote controller 40 is a dedicated remote controller for the lighting device 20. The remote controller 40 receives a user's operation and transmits a control signal to the lighting device 20 in accordance with the received operation, thereby controlling the light emission of the lighting device 20. The remote controller 40 and the lighting device 20 (first wireless communication unit 21) communicate directly (in other words, local communication), and no relay device is involved in the communication. The remote controller 40 transmits the control signal to the lighting device 20 by radio wave communication, for example, but may also transmit the control signal to the lighting device 20 by infrared communication.

[0022] The information terminal 50 is realized by installing a predetermined application program on a general-purpose mobile terminal such as a smartphone or a tablet terminal. The information terminal 50 can control the light emission of the lighting device 20 by receiving a user's operation and transmitting a control signal to the lighting device 20 in accordance with the received operation. The light emission control includes at least one of dimming control and color adjustment control of the lighting device 20. The information terminal 50 and the lighting device 20 (second wireless communication unit 22) communicate with each other via the information processing server 60 (in other words, communication through the wide area communication network 80). The information terminal 50 includes an operation receiving unit 51, a display unit 52, a communication unit 53, an information processing unit 54, and a storage unit 55.

[0023] The operation reception unit 51 receives operations from a user. Specifically, the operation reception unit 51 is realized by a touch panel or the like.

[0024] The display unit 52 displays an image and is realized by a display panel such as a liquid crystal panel or an organic EL panel.

[0025] The communication unit 53 is a communication circuit (communication module) that enables the information terminal 50 to connect to the wide area communication network 80 by wireless communication through a mobile communication network. In other words, the communication unit 53 is a communication circuit that enables the information terminal 50 to communicate with the lighting device 20 via the server.

[0026] The information processing unit 54 performs processing to transmit a control signal to the lighting device 20 in response to a user operation accepted by the operation accepting unit 51. The information processing unit 54 is realized by, for example, a microcomputer, but may also be realized by a processor or a dedicated circuit.

[0027] The information processing unit 54 includes, as functional components, a control unit 56 and an adjustment unit 57. The functions of the control unit 56 and the adjustment unit 57 are realized by hardware such as a microcomputer or processor constituting the information processing unit 54 executing a computer program (software) stored in the storage unit 55. This computer program includes the above-mentioned predetermined application program, and in other words, the predetermined application program is a computer program for operating a general-purpose mobile terminal as the information terminal 50.

[0028] The storage unit 55 is a storage device that stores computer programs and the like executed by the information processing unit 54. The storage unit 55 is realized by, for example, a semiconductor memory.

[0029] The information processing server 60 is a cloud server that relays a control signal transmitted by the information terminal 50. When the information processing server 60 receives a control signal from the information terminal 50 via the wide area communication network 80, it transmits the received control signal to the lighting device 20. The information processing server 60 is located outside the indoor space in which the lighting device 20 is installed.

[0030] The video distribution server 70 is a cloud server that distributes video content to the information terminal 50. When the video distribution server 70 receives a video content distribution request from the information terminal 50 via the wide area communication network 80, the video distribution server 70 distributes the video content specified in the received distribution request to the information terminal 50. The video distribution server 70 is located outside the indoor space in which the lighting device 20 is installed.

[0031] [Linked operation of video content and lighting equipment] The lighting system 10 is capable of performing a linked operation in which video content is played on the display unit 52 of the information terminal 50 and, at the same time, the lighting device 20 emits light in a light emission pattern corresponding to the video content being played. Figure 2 is a diagram showing an overview of the linked operation.

[0032] The following describes the linked operation of the lighting system 10 with reference to a sequence diagram. FIG.

[0033] A user performs a selection operation to select video content on information terminal 50 that is running a predetermined application program. Fig. 4 is a diagram showing an example of a selection screen displayed on display unit 52 of information terminal 50 when a selection operation is performed, and the selection operation is, for example, a tap operation on an object corresponding to video content on the selection screen of Fig. 4.

[0034] Operation accepting unit 51 of information terminal 50 accepts a selection operation (S11). Here, storage unit 55 stores URLs of video content delivery destinations (i.e., storage locations of video content in video delivery server 70) that can be selected from a selection screen when installing a predetermined application program, etc. Control unit 56 uses communication unit 53 to send a delivery request for the selected video content to video delivery server 70 (S12).

[0035] The video distribution server 70 receives the distribution request and streams the video content corresponding to the URL specified in the received distribution request (i.e., the video content selected in step S11) (S13). The communication unit 53 of the information terminal 50 receives the video content, and the control unit 56 acquires the received video content and plays the acquired video content using the display unit 52 (S14).

[0036] After the process of step S11, the control unit 56 transmits a control signal to the information processing server 60 using the communication unit 53 in parallel with the transmission of the distribution request (S15). Note that, if the information terminal 50 is communicatively connected to the wireless router 30, the control signal is transmitted to the information processing server 60 via the wireless router 30.

[0037] The information processing server 60 transmits the received control signal to the lighting device 20 (S16). The second wireless communication unit 22 of the lighting device 20 receives the control signal via the wireless router 30 (not shown in FIG. 3).

[0038] Here, the control signal specifies identification information (such as a number) of the video content selected in step S11, and light emission pattern information associating the identification information of the video content with a light emission pattern is stored in advance in storage unit 25 of lighting device 20. The light emission pattern means information for changing at least one of the brightness and color of light-emitting unit 23 over time, such as 50% dimming after 3 seconds, 3500K color adjustment after 8 seconds, etc. The light emission pattern is appropriately created in advance to correspond to the video content.

[0039] The lighting control unit 24 refers to the light emission pattern information stored in the memory unit 25 to identify the light emission pattern associated with the identification information of the video content specified in the control signal received in step S16, and causes the light emission unit 23 to emit light in accordance with the identified light emission pattern (S17).

[0040] In this way, the lighting system 10 (control unit 56) plays the video content acquired by sending a video content distribution request, and by sending a control signal to the lighting device 20, can control the lighting of the lighting device 20 (instruct the lighting pattern) so as to be linked to the video content being played.

[0041] [Start timing adjustment operation] The transmission of the video content distribution request in step S12 and the transmission of the control signal in step S15 are performed almost simultaneously when the selection operation is accepted in step S11. However, the time from when the video content distribution request is transmitted to when playback of the video content starts, and the time from when the control signal is transmitted to when lighting device 20 starts emitting light according to the light emission pattern, vary depending on the communication environment, and therefore there may be a mismatch between the timing at which playback of the video content starts and the timing at which lighting device 20 starts emitting light.

[0042] Therefore, in lighting system 10, an adjustment screen is displayed on display unit 52 of information terminal 50 that is running a predetermined application program, and the user can adjust the timing at which playback of video content starts and the timing at which lighting device 20 starts to emit light by operating the adjustment screen. Fig. 5 is a diagram showing an example of the adjustment screen.

[0043] 5, the user can delay the light emission start timing of lighting device 20 from the playback start timing of the video content within a predetermined range of 1 second to 10 seconds by operating the slider to specify an adjustment amount (delay amount). When operation acceptance unit 51 accepts the operation to specify the adjustment amount, adjustment unit 57 instructs control unit 56 to delay the transmission of the control signal in step S15 by the specified adjustment amount from the transmission of the video content distribution request in step S12.

[0044] This allows the user to, through trial and error, synchronize the playback start timing of the video content with the light emission start timing of the lighting device 20. In other words, the lighting system 10 can reduce the misalignment between the playback start timing of the video content and the light emission start timing of the lighting device 20.

[0045] Note that, on the adjustment screen, the timing at which playback of the video content starts may be delayed, within a predetermined range, from the timing at which light emission starts of lighting device 20. In other words, adjustment unit 57 only needs to be able to adjust at least one of the timing at which playback of the video content starts and the timing at which a control signal is transmitted (in other words, the timing at which lighting device 20 starts light emission control based on the control signal).

[0046] [Change the playback speed of video content] While the video content is being played back, the user can change the playback speed of the video content by performing a predetermined operation to change the playback speed of the video content on operation reception unit 51. In order to change the playback speed of the light emission pattern in conjunction with the video content, control unit 56 uses communication unit 53 to send a change instruction signal to lighting device 20 to change the playback speed.

[0047] The change instruction signal is transmitted to the lighting device 20 via the information processing server 60 and the wireless router 30, similar to the control signal described above. In this case, the playback speed of the video content is immediately reflected, whereas it is thought that it takes some time for the change instruction signal to be received by the lighting device 20. For this reason, the above-mentioned predetermined operation to instruct a change in the playback speed may cause the video content and the light emission pattern to become out of synchronization.

[0048] Therefore, when the predetermined operation is performed (when a change in the playback speed is instructed), control unit 56 transmits a change instruction signal to lighting device 20, and changes the playback speed of the video content after a delay time has elapsed since the transmission of the change instruction signal. In other words, control unit 56 does not immediately reflect the change in the playback speed of the video content, but reflects it after a delay time has elapsed.

[0049] This allows the lighting system 10 to prevent the video content and the light emission pattern from becoming out of synchronization due to a predetermined operation that instructs a change in the playback speed.

[0050] The delay time is a fixed delay time that is empirically or experimentally determined as appropriate by, for example, a designer of the lighting system 10, but may also be adjusted by the user via an adjustment screen similar to that shown in Fig. 5. Furthermore, when periodically communicating with the lighting device 20 for purposes such as alive monitoring, the control unit 56 may measure the time it takes for a signal transmitted by the information terminal 50 to reach the lighting device 20, and use the most recently measured time as the delay time.

[0051] [Variation 1: Example in which the start timing is adjusted by the lighting device] In the above embodiment, an example has been described in which the timing at which lighting device 20 starts light-emission control is adjusted by information terminal 50. However, the timing at which lighting device 20 starts light-emission control may be adjusted by lighting device 20 itself. In other words, a component equivalent to adjustment unit 57 may be included in lighting device 20.

[0052] For example, the user may set an adjustment amount (delay amount) for the lighting device 20 by operating the remote controller 40. In this case, the information terminal 50 transmits the video content distribution request in step S12 and the control signal in step S15 almost simultaneously, but the adjustment unit of the lighting device 20 issues a command to the lighting control unit 24 to start light emission control after a time corresponding to the adjustment amount has elapsed since receiving the control signal.

[0053] This allows the user to, through trial and error, synchronize the playback start timing of the video content with the light emission start timing of the lighting device 20. In other words, the lighting system 10 can reduce the misalignment between the playback start timing of the video content and the light emission start timing of the lighting device 20.

[0054] Furthermore, when the adjustment unit of the lighting device 20 periodically communicates with the information terminal 50 for purposes such as alive monitoring, the adjustment unit may measure the time it takes for a signal transmitted from the information terminal 50 to reach the lighting device 20, and shorten the adjustment amount if the most recently measured time is long, or lengthen the adjustment amount if the most recently measured time is short. In other words, the adjustment amount may be determined by the adjustment unit itself, rather than by the user.

[0055] [Variation 2: Example in which start timing is adjusted by the information processing server] Furthermore, the timing at which the lighting device 20 starts light emission control may be adjusted by the information processing server 60. That is, a component equivalent to the adjustment unit 57 may be included in the information processing server 60.

[0056] For example, when the adjustment unit of the information processing server 60 periodically communicates with the lighting device 20 and the information terminal 50 for purposes such as alive monitoring, the adjustment unit measures a first time period required for a signal transmitted by the information terminal 50 to reach the information processing server 60, and a second time period required for a signal transmitted by the information processing server 60 to reach the lighting device 20.

[0057] When the information processing server 60 receives a control signal from the information terminal 50, it transmits the received control signal to the lighting device 20 after a time corresponding to the adjustment amount has elapsed. At this time, if the total time of the most recently measured first time and second time is long, the adjustment amount may be shortened, and if the total time is short, the adjustment amount may be lengthened. In this way, the information processing server 60 can reduce the difference between the timing at which the playback of the video content starts and the timing at which the lighting device 20 starts emitting light.

[0058] [Other variations] As described above, the user can select and view one of the multiple video contents through the selection screen. The information processing unit 54 of the information terminal 50 may store playback history information of the video contents in the storage unit 55 and display the playback history information on the display unit 52 in response to a predetermined operation by the user. For example, the information processing unit 54 may display the total number of playbacks of each of the multiple video contents and the number of playbacks by date of each of the multiple video contents.

[0059] Furthermore, in the above embodiment, the video content is played on display unit 52 of information terminal 50, but it is not essential that the video content be played on display unit 52 of information terminal 50. The video content may also be played on a television, in which case the video content may be distributed from video distribution server 70 to the television, or may be distributed from the video distribution server to information terminal 50 and then transferred to the television.

[0060] In the above embodiment, the information processing server 60 is assumed to be a server used by a manufacturer and distributor of the lighting device 20, and the video distribution server 70 is assumed to be a server used by a video distribution company. Here, if a manufacturer and distributor of the lighting device 20 independently creates and distributes videos, the information processing server 60 and the video distribution server may be a single server (single system) used by the manufacturer.
