[0011] Embodiment 1 Fig. 1 is a perspective view of a lighting fixture 1 according to the first embodiment. Fig. 2 is a plan view of the lighting fixture 1 according to the first embodiment. Fig. 2 is a diagram showing the lighting fixture 1 as viewed from below. The lighting fixture 1 comprises a scattering plate 12 which is a main light-emitting surface, a surrounding light-emitting frame 131 which is a surrounding light-emitting surface, and a surrounding light-emitting frame 132 which is a non-light-emitting part. The scattering plate 12 emits light to imitate a blue sky. The surrounding light-emitting frame 131 represents sunlight shining through and is self-luminous. The surrounding light-emitting frame 132 represents the shadow cast when sunlight shines through.

[0012] FIG. 3 is an exploded perspective view of the lighting fixture 1 according to the first embodiment. The lighting fixture 1 has a surrounding light emitting frame 13 consisting of surrounding light emitting frames 131 and 132. A scattering plate 12 is built in on the surrounding light emitting frame 13. In order to illuminate the surrounding light emitting frame 131, surrounding light emitting LED boards 15, which are LED light sources, are arranged. Of the four sides around the scattering plate 12, main light emitting surface LED boards 14, which are LED light sources, are arranged on two opposing sides. A reflecting sheet 18 is built in on the scattering plate 12. A control power supply 16 and a control unit 17 for supplying and controlling electricity to the main light emitting surface LED board 14 and surrounding light emitting LED board 15 are arranged on the reflecting sheet 18. These members are stored in the housing 11. The main light emitting surface LED board 14 and surrounding light emitting LED board 15 correspond to a light source unit.

[0013] 3, the screws, springs, and members electrically connecting the main light-emitting surface LED board 14 and the ambient light-emitting LED board 15 used when assembling the lighting fixture 1 are omitted. Also omitted are the control power supply 16, the frame structure supporting the control unit 17, and the wiring and terminal block that supply power to the control power supply 16. Also omitted are the communication lines that control the control power supply 16 and the control controller beyond that.

[0014] 4 is a cross-sectional view of the lighting fixture 1 according to embodiment 1. The scattering plate 12 includes a scatterer 121. The surrounding light emitting LED board 15 is disposed near the surrounding light emitting frame 131. The main light emitting surface LED board 14 is disposed near the side surface of the scattering plate 12.

[0015] FIG. 5 is a diagram showing the configuration of the lighting control system 100 according to the first embodiment. Three LED boards 15 for ambient light emission are connected in series to each other and connected to a control power supply 16. Two LED boards 14 for main light emission are connected in series to each other and connected to a control power supply 16. In this embodiment, an example in which three of the four sides of the ambient light emission frame 13 emit light is shown. This is not limited to this, and only two adjacent sides may emit light. In this case, two LED boards 15 for ambient light emission are connected in series to each other and connected to a control power supply 16. In this embodiment, an example in which two LED boards 14 for main light emission are arranged on both end faces of the scattering plate 12 facing each other is shown. This is not limited to this, and a configuration in which only one LED board 14 for main light emission is provided and light enters from only one of the four sides of the scattering plate 12 may be shown.

[0016] The control power supply 16 is connected to the control unit 17, and the control unit 17 is connected to the control controller 2. The control unit 17 may be incorporated into the control power supply 16 and integrated with it. In this case, the control power supply 16 is directly connected to the control controller 2. The control controller 2 is connected to the communication controller 3, and the control controller 2 is connected to the cloud server 6 via the network 5. The cloud server 6 can access information 7 on the network, such as news, weather forecasts, SNS (Social Networking Service) information, time information, and government agency / organization information, via the network 5. The government agency / organization information includes, for example, information on standards. The cloud server 6 corresponds to a control device that controls the lighting state of the light source unit. The cloud server 6 communicates with the lighting fixture 1 to control the lighting state of the light source unit.

[0017] Furthermore, the communication controller 3 communicates with a voice recognition unit 8, an information terminal 9, and a setting remote control 10 via wireless communication or wired communication. The voice recognition unit 8, the information terminal 9, and the setting remote control 10 correspond to input devices for inputting natural language. The control controller 2 and the communication controller 3 may be integrated into one unit. The communication controller 3 and the cloud server 6 may be integrated into one unit. The control controller 2, the communication controller 3, and the cloud server 6 may be integrated into one unit. Furthermore, the cloud server 6 does not need to be connected to a network, and may function as an edge computer.

[0018] 6 is a diagram showing the configuration of the main light-emitting surface LED board 14 according to embodiment 1. In the main light-emitting surface LED board 14, white LEDs 141, blue LEDs 142, and green LEDs 143 are arranged alternately. The white LEDs 141 are arranged and connected to a circuit pattern 144. The blue LEDs 142 are arranged and connected to a circuit pattern 145. The green LEDs 143 are arranged and connected to a circuit pattern 146. This allows the white LEDs 141, blue LEDs 142, and green LEDs 143 to be independently controlled to be turned on and off.

[0019] In FIG. 6, the white LEDs 141, the blue LEDs 142, and the green LEDs 143 are arranged in a line. The thickness of the scattering plate 12 into which the light from the main light-emitting surface LED substrate 14 enters is, for example, 5 mm, and the sizes of the white LEDs 141, the blue LEDs 142, and the green LEDs 143 are, for example, 3 mm. With the arrangement of the LEDs as shown in FIG. 6, the light can be efficiently entered into the scattering plate 12. On the other hand, when the sizes of the white LEDs 141, the blue LEDs 142, and the green LEDs 143 are less than 3 mm, or when the thickness of the scattering plate 12 is greater than 5 mm, the white LEDs 141, the blue LEDs 142, and the green LEDs 143 do not have to be arranged in a line. The white LEDs 141, the blue LEDs 142, and the green LEDs 143 may be arranged in a plurality of rows, for example, two or more rows. In addition, the arrangement order of the white LEDs 141, the blue LEDs 142, and the green LEDs 143 is not limited as long as the light from the white LEDs 141, the blue LEDs 142, and the green LEDs 143 is sufficiently mixed inside the scattering plate 12. In addition, in Fig. 6, the circuit patterns 144, 145, and 146 are connected in parallel to configure one parallel circuit, but two or more parallel circuits may be configured.

[0020] 7 is a diagram showing the configuration of ambient light emitting LED board 15 according to embodiment 1. In ambient light emitting LED board 15, high color temperature white LEDs 151 and low color temperature white LEDs 152 are arranged alternately. High color temperature white LEDs 151 are arranged and connected to circuit pattern 153. Low color temperature white LEDs 152 are arranged and connected to circuit pattern 154. This allows the lighting of high color temperature white LEDs 151 and low color temperature white LEDs 152 to be controlled independently.

[0021] In FIG. 7, the high color temperature white LEDs 151 and the low color temperature white LEDs 152 are arranged in a line. The size of the high color temperature white LEDs 151 and the low color temperature white LEDs 152 is, for example, 3 mm. Depending on the size of the high color temperature white LEDs 151 and the low color temperature white LEDs 152, the high color temperature white LEDs 151 and the low color temperature white LEDs 152 may not be arranged in a line. The high color temperature white LEDs 151 and the low color temperature white LEDs 152 may be arranged in two or more rows. In this case, as long as the light of the high color temperature white LEDs 151 and the low color temperature white LEDs 152 is sufficiently mixed, the arrangement order of the high color temperature white LEDs 151 and the low color temperature white LEDs 152 is not limited. In addition, in FIG. 7, the circuit patterns 153 and 154 are connected in parallel to form one parallel circuit, but two or more parallel circuits may be formed.

[0022] 8 is a block diagram showing a configuration of a lighting control system 100 according to the first embodiment. The control power supply 16 has a DC power supply circuit 161 as a primary side input. The DC power supply circuit 161 rectifies commercial power supply to convert it to DC. The DC power supply circuit 161 supplies the generated DC power to an output control circuit 162. The output control circuit 162 is connected to the control unit 17 and receives a control command from the control unit 17. In accordance with the control command, the output control circuit 162 supplies power to a first lighting circuit 163a, a second lighting circuit 163b, a third lighting circuit 163c, a fourth lighting circuit 163d, and a fifth lighting circuit 163e, and controls the output of each circuit.

[0023] The white LED 141 receives power from the first lighting circuit 163a, the blue LED 142 receives power from the second lighting circuit 163b, and the green LED 143 receives power from the third lighting circuit 163c, and they are all turned on. Also, the high color temperature white LED 151 receives power from the fourth lighting circuit 163d, and the low color temperature white LED 152 receives power from the fifth lighting circuit 163e, and they are all turned on.

[0024] FIG. 9 is a diagram showing the luminous colors of the main light-emitting surface and the surrounding light-emitting surface in each scene according to the first embodiment. In a daytime scene, the main light-emitting surface has the color of the daytime sky, and the surrounding light-emitting surface is 5000K. In a morning and evening scene, the main light-emitting surface has the color of the morning and evening sky, and the surrounding light-emitting surface is 3000K. In a sunrise and sunset scene, the main light-emitting surface has the color of the sunrise and sunset sky, and the surrounding light-emitting surface is 3000K. In a nighttime scene, the main light-emitting surface has the color of the night sky, and the surrounding light-emitting surface is 3000K. In a daytime lights-out scene, the main light-emitting surface is turned off, and the surrounding light-emitting surface is 5000K. In a completely lights-out scene, the main light-emitting surface and the surrounding light-emitting surface are turned off. The types of scenes and the luminous colors of each scene are merely examples, and are not limited to those shown in FIG. 9.

[0025] Fig. 10 is a diagram showing an example of the initial value of the schedule setting according to the first embodiment. The lighting control system 100 has a function called fade, which gradually changes the color and brightness from the previous scene to the next scene. The fade time is basically one hour, and the user can arbitrarily switch it by setting a value such as one second or ten minutes. In the example of Fig. 10, a fade time of one hour is set as the initial value.

[0026] In the example schedule setting in FIG. 10, the scene continues until 4:00, fades over an hour, and transitions to a sunrise / sunset scene at 5:00. It fades over another hour and transitions to a morning / evening scene at 6:00. It fades over another hour and transitions to a daytime scene at 7:00, and then the daytime scene continues until 15:00. It then fades over an hour from 15:00 and transitions to a morning / evening scene at 16:00. It fades over another hour and transitions to a sunrise / sunset scene at 17:00. It fades over another hour and transitions to a nighttime scene at 18:00, and then the nighttime scene continues until 4:00.

[0027] FIG. 11 is a diagram for explaining a learning function of the lighting control system 100 according to the first embodiment. The learning function is provided in, for example, the cloud server 6. The cloud server 6 acquires learning data 63, 64, 65, and a database 61 in the cloud server 6 performs learning by machine learning, deep learning, or reinforcement learning. The database 61 may be an AI (Artificial Intelligence) system. The learning data 63 is a user manual for lighting control settings, that is, an instruction manual or specification for the lighting control system 100. The learning data 64 is default values ​​for the lighting control settings, that is, initial values. The learning data 65 is natural language.

[0028] The learning data 63, 64 may be acquired from information stored in any device in the lighting control system 100, or may be acquired via the network 5. The learning data 65 may be acquired from information input in a natural language by a user from the voice recognition unit 8, the information terminal 9, or the setting remote control 10, or may be acquired via the network 5.

[0029] The learning function based on the learning data 63, 64 will be described in detail. In the learning phase, the cloud server 6 acquires the learning data 63, 64 including the instruction manual, specifications or initial values ​​of the lighting control settings of the lighting control system 100. The cloud server 6 uses the acquired learning data 63, 64 to generate a trained model for changing a second part, which is a part of the lighting control settings, from the instruction manual, specifications or initial values ​​of the lighting control settings of the lighting control system 100. The second part of the lighting control settings will be described later.

[0030] In the utilization phase, the cloud server 6 acquires instructions, specifications, or initial values ​​of the lighting control settings of the lighting control system 100. Furthermore, the cloud server 6 changes the second part of the lighting control settings using the trained model for changing the second part of the lighting control settings based on the instructions, specifications, or initial values ​​of the lighting control settings of the lighting control system 100.

[0031] When using the learning data 63, the cloud server 6 learns, for example, what setting contents exist in the schedule setting. When using the learning data 64, the cloud server 6 learns the initial values ​​of various settings that the lighting control system 100 has at the time of shipment from the factory.

[0032] Next, the learning function based on the learning data 65 will be described in detail. In the learning phase, the cloud server 6 acquires the learning data 65 including a natural language. The cloud server 6 uses the acquired learning data 65 to generate a trained model for extracting command elements, which will be described later, from the natural language. When using the learning data 65, the cloud server 6 learns grammar in Japanese, for example. The trained model may be a trained model for extracting the contents intended by the user from the context.

[0033] In the utilization phase, the cloud server 6 acquires input information in a natural language. The cloud server 6 further extracts command elements from the input information using a trained model for extracting command elements from the natural language.

[0034] FIG. 12 is a diagram for explaining a learning function via a network 5 of the lighting control system 100 according to the first embodiment. The cloud server 6 may acquire information 7 on the network as learning data via the network 5, and the database 61 in the cloud server 6 may perform learning by machine learning, deep learning, or reinforcement learning. The information 7 is, for example, news, weather forecast, SNS information, and time information. The SNS information is, for example, information on Facebook (registered trademark) and Twitter (registered trademark). While FIG. 11 shows an example of learning specific information such as a specification, in the example of FIG. 12, information on any network is learned instead of specific information, as in the learning form of a large-scale language model represented by ChatGPT (trademark).

[0035] Next, the learning function based on the information 7 on the network will be described in detail. In the learning phase, the cloud server 6 acquires learning data including the information 7 on the internet. The cloud server 6 uses the acquired learning data to generate a trained model for changing a second part (described later) of the lighting control settings from the information 7 on the internet.

[0036] In the utilization phase, the cloud server 6 acquires information 7 on the internet. Furthermore, the cloud server 6 changes the second part of the lighting control settings using the trained model for changing the second part of the lighting control settings based on the information 7 on the internet. As described above, training using training data 65 including natural language may be performed based on the information 7 on the internet.

[0037] When the control controller 2, the communication controller 3, or the control unit 17 in the lighting fixture 1 has the same function as the cloud server 6, the learning function may be provided by the control controller 2, the communication controller 3, or the control unit 17. In addition, when the control unit 17 and the controlled power supply 16 are integrated, the controlled power supply 16 may have the learning function. In this case, communication with the cloud server 6 via a network is not necessary, and the device having the learning function may operate as an edge computer.

[0038] Fig. 13 is a diagram illustrating a method for changing lighting control settings by the lighting control system 100 according to the first embodiment. Here, an example in which the lighting control settings are schedule settings will be described. In Fig. 13, input information is input in natural language by a user to an input device such as a voice recognition unit 8, an information terminal 9 or a setting remote control 10. Here, the natural language is also called a natural dialogue language.

[0039] Here, as an example, it is assumed that the user inputs input information 90 by speech or text input, which has the content "The schedule for the lighting devices is morning at 8:00, night at 21:00, and off at midnight. Please turn them on slowly over 4 hours at night." The input information 90 is analyzed in a database 61 in the cloud server 6. The cloud server 6 extracts command elements and command types from the input information 90 in natural language from the user. The command elements are parts of the input information 90 in natural language that correspond to specific commands. In this case, the command elements may be extracted from the input information 90 using a trained model for extracting command elements from natural language.

[0040] Based on the analysis result of the input information 90, the cloud server 6 changes the lighting control settings for controlling the light source unit. The command type indicates the source of information for changing the lighting control settings. The source of information includes the control controller 2, the network 5, etc. The cloud server 6 acquires information from the source according to the command type, and changes the lighting control settings based on the acquired information and command elements. In the example of FIG. 13, the command type is the control controller 2 in order to acquire information such as the current schedule setting.

[0041] In this embodiment, the cloud server 6 changes the first part of the lighting control settings corresponding to the extracted command element and the second part related to the first part. In the example of Fig. 13, as the first part corresponding to the command element, the morning side of the morning / evening scene is changed to 8:00 and the night scene is changed to 21:00.

[0042] The second part of the lighting control setting is a part of the lighting control setting that is not instructed to be changed by the command element. The second part may be changed using a trained model for changing the second part, obtained by the above-mentioned deep learning or the like. In this case, the information acquired according to the command type corresponds to information acquired when changing the second part of the lighting control setting using the trained model. From the learning result, for example, midnight is inferred as 11:00 p.m. to 3:00 a.m., and the all-lights-off scene is set to 11:00 p.m. to 3:00 a.m. In addition, the command element specifies the transition time from day to night as 4 hours. From the learning result, taking into account a fade time of one hour, the morning and evening scene on the evening side is set to 18:00, the sunrise and sunset scene on the evening side is set to 20:00, and the night scene is set to 21:00.

[0043] The setting contents obtained by changing the first and second parts of the original lighting control setting in this way are transmitted as extraction and conversion information 91 from cloud server 6 to control controller 2. Lighting fixture 1 receives extraction and conversion information 91 via control unit 17. As a result, lighting fixture 1 performs a control operation in accordance with extraction and conversion information 91.

[0044] In this embodiment, learning is performed based on learning data 63, 64 including the instruction manual, specifications or initial values ​​of the lighting control settings of the lighting control system 100, so that the second part of the lighting control settings that is not directly indicated in the input information can be optimally changed.

[0045] Fig. 14 is a diagram illustrating an example of lighting control settings changed by lighting control system 100 of embodiment 1. Fig. 14 shows schedule settings changed based on input information 90 of Fig. 13 with respect to the initial values ​​of the schedule settings in Fig. 10. In input information 90, only a portion of the schedule settings in Fig. 10 is specified. In this embodiment, in database 61 of cloud server 6, in response to the specification of only a portion, other contents are also optimized and proposed to the user as shown in Fig. 14.

[0046] In the changed schedule setting, the scene is a night scene until 6:00, fades over an hour, and then transitions to a sunrise / sunset scene at 7:00. It fades over another hour and transitions to a morning / evening scene at 8:00. It fades over another hour and transitions to a daytime scene at 9:00. At this time, the time interval from the sunrise / sunset scene to the daytime scene is maintained from before the change. After that, the daytime scene continues until 17:00. It fades over an hour from 17:00, transitions to a morning / evening scene at 18:00, and the morning / evening scene continues for one hour until 19:00. It then fades over an hour from 19:00, and transitions to a sunrise / sunset scene at 20:00. It fades over another hour and transitions to a night scene at 21:00, and then the night scene continues until 22:00. It fades over an hour from 22:00, and all the lights are turned off at 23:00. The lights out scene is maintained for four hours from 11:00 PM to 3:00 AM. Then it fades for one hour from 3:00 AM, transitions to a night scene at 4:00 AM, and the night scene is maintained for two hours until 6:00 AM.

[0047] FIG. 15 is a diagram for explaining a method of changing a lighting control setting by the lighting control system 100 according to the first embodiment. Here, an example will be described in which the lighting control setting is a date or time setting. As an example, it is assumed that the user inputs input information 90 with the content "Please set the time on the controller to the current date and time" by speech or character input. The input information 90 is analyzed in the database 61 in the cloud server 6. The cloud server 6 extracts a command element and a command type from the input information 90 in natural language from the user. At this time, the command element may be extracted from the input information 90 using a trained model for extracting command elements from natural language.

[0048] The cloud server 6 acquires information from a source according to the command type, and changes the lighting control settings based on the acquired information and command elements. In the example of FIG. 15, the command type is network 5 to acquire current date and time information. The cloud server 6 queries date and time information from information 7 on the network via the network 5. The cloud server 6 acquires, for example, "April 10, 2023, 15:35:22" as the current date and time information. The cloud server 6 generates setting contents that change the date or time setting of the lighting control settings based on the acquired date and time information and command elements.

[0049] The generated setting contents are transmitted to the control controller 2 as the extraction / conversion information 91. The cloud server 6 may have the user confirm the date and time information acquired from the network 5, and may generate the setting contents by adding a time corresponding to the time lag, such as one minute, to the date and time information, taking into account the time lag for confirmation. In this case, the date and time information of the setting contents is, for example, "April 10, 2023, 15:36:22". The cloud server 6 may convert the time from when the information is acquired until the user confirms and approves it, or the time from when the information is acquired until the setting is completed, and add the converted time to the date and time information to generate the setting contents. After the user approves, the cloud server 6 may acquire the date and time information from the network 5 again and generate the setting contents using the latest date and time information. The cloud server 6 may transmit the setting contents to the control controller 2, and after completing the setting, may confirm with the user.

[0050] When changing the date or time setting, other parts of the lighting control settings related to the date or time setting may be changed, i.e., when changing the date or time setting, in addition to the first part corresponding to the command element, a second part of the lighting control settings that is not instructed to be changed by the command element may be changed.

[0051] 16 and 17 are diagrams showing examples of input devices for inputting natural language according to the first embodiment. Input information in natural language can be accepted by character input or voice input. In Figs. 16 and 17, the input devices are an information terminal 9 and a setting remote control 10, respectively, and examples are shown in which input information is accepted by character input. A user can input input information in natural language through an input interface possessed by the input device.

[0052] 18 and 19 are diagrams showing a state in which the setting contents are being confirmed by the user using the input device according to the first embodiment. Figs. 18 and 19 respectively show a state in which the setting contents proposed by the lighting control system are being confirmed by the user using the information terminal 9 and the setting remote control 10. The setting contents are displayed on a screen which is a confirmation interface of the input device. The user confirms the setting contents displayed on the screen and inputs whether or not to approve the setting contents according to the instructions shown on the screen.

[0053] Although not shown, when a voice recognition unit 8 is used as an input device, the user confirms the setting contents by voice feedback. When the voice recognition unit 8 is used, the setting contents may be confirmed through the screen of any terminal.

[0054] FIG. 20 is a diagram showing an operation flow of the lighting control system 100 according to the first embodiment. In the initial state, the number of inquiries is 0. In step 101, the user inputs the contents to be set as input information from the voice recognition unit 8, the information terminal 9, or the setting remote control 10. The input information is input in the form of a dialogue with the user using AI such as ChatGPT (trademark). At this time, the lighting control system 100 adds 1 to the number of inquiries to make it 1. Next, in step 102, the communication controller 3 receives the input information and transmits it to the cloud server 6.

[0055] In step 103, the cloud server 6 extracts a command element and a command type from the input information. In step 104, the cloud server 6 converts the command element into a control command. Here, extracting a command element means extracting a word that is determined to be a command element from a sentence spoken by a user in natural language. Also, converting into a control command means replacing the command element with a character string or a signal that the lighting control system 100 or the cloud server 6 can receive as a command.

[0056] When replacing the command element with a control command, the cloud server 6 determines which of the multiple types of lighting control settings the command element corresponds to, based on the context of the information input in the user's natural language. The cloud server 6 also determines whether to issue the control command directly to the control controller 2 or to perform an information search on the network 5 or the like, depending on the command type. Types of command elements include schedule settings for setting a scene, time settings, and operating condition settings for setting the operation of the control controller 2. Command types include the control controller 2, the network 5, and the like.

[0057] In step 105, the cloud server 6 compares the inquiry content according to the control command with the command type. In step 106, the cloud server 6 makes an inquiry to the network 5 or the control controller 2 based on the comparison result. If the number of inquiries is two or more and the command type is the control controller 2, no inquiry is made to the control controller 2, and the process proceeds to step 114 described below without obtaining new information from the control controller 2. If the command type is the network 5, an inquiry is made regardless of the number of inquiries.

[0058] When an inquiry is made to the network 5, the network server searches for information on the network 5, such as date and time information, in step 107. As a result, the desired information is acquired from the network 5 in step 108. In step 109, the cloud server 6 receives the queried information. Next, in step 114, setting contents are generated using the queried information.

[0059] If an inquiry is made to the controlling controller 2 in step 106, the cloud server 6 notifies the controlling controller 2 of the inquiry content via the communication controller 3 in step 110. The controlling controller 2 transmits the queried information via the communication controller 3 in step 111. In the case of schedule setting, the transmitted information is the schedule information currently set in the controlling controller 2. In step 112, the communication controller 3 receives the information transmitted by the controlling controller 2 and notifies the cloud server 6. In step 113, the cloud server 6 receives the queried information. In step 114, setting content is generated using the queried information.

[0060] In step 106, if the command type is the control controller 2 and the number of inquiries is two or more, the cloud server 6 does not read new information from the control controller 2, but makes further changes to the previously generated setting contents.

[0061] In step 101, the user does not need to issue commands for all changes to the lighting control settings. For example, if the current lighting control settings are 50% dimming at 8:00, 100% dimming at 12:00, and 80% dimming at 18:00, the user may issue only a command for 90% dimming at 12:00. In this case, in step 114, the cloud server 6 generates the settings by changing a first portion of the lighting control settings that corresponds to the command element "90% dimming at 12:00" and a second portion related to the first portion. As a result, the settings become, for example, 50% dimming at 8:00, 90% dimming at 12:00, and 80% dimming at 18:00.

[0062] In step 115, cloud server 6 notifies the user of the generated setting contents as a change proposal. If the user does not approve the change proposal in the user's consent confirmation in step 116, the process returns to step 101 in order to ask the user about further changes he or she would like to make. At this time, the number of inquiries is incremented by 1. For example, if the number of inquiries is 1 at the time of step 116, the number of inquiries becomes 2.

[0063] If the user gives permission, then in step 117, cloud server 6 sends the changed settings to control controller 2 via communication controller 3. In step 118, control controller 2 reflects the settings and starts operating lighting fixture 1 in accordance with the settings. In lighting fixture 1, in step 119, control unit 17 receives the command from control controller 2 and sends a command to controlled power supply 16. In step 120, controlled power supply 16 operates in accordance with the command. As a result, lighting fixture 1 operates in accordance with the settings.

[0064] In this way, the cloud server 6 notifies the user of the setting contents obtained by changing the first and second parts of the lighting control settings (step 115), and if the user approves the setting contents, controls the light source unit according to the setting contents. If the user does not approve the setting contents, the cloud server 6 accepts input information in natural language from the user again (step 101). The cloud server 6 extracts a command element and a command type from the input information accepted again, and further changes the part of the setting contents that corresponds to the command element and the part related to the part that corresponds to the command element (steps 102 to 114). The cloud server 6 notifies the user of the changed setting contents (step 115), and if the user approves the changed setting contents, controls the light source unit according to the changed setting contents (steps 116 to 120).

[0065] Note that the cloud server 6 has already acquired the latest information from the control controller 2 when the number of inquiries is 1. Therefore, when the user does not approve the setting contents and the number of inquiries after receiving input information from the user again is 2 or more, steps 110 to 113 can be omitted.

[0066] In this way, if the user is not satisfied with the settings, the system allows the user to input further changes, changes the settings, and proposes them to the user again. In this way, settings that meet the user's wishes can be constructed through conversation.

[0067] As described above, according to the present embodiment, a command element is extracted from input information in natural language from a user, and a first part of the lighting control settings corresponding to the command element and a second part related to the first part are changed. In other words, the user only needs to specify the part that the user particularly wants to change, and the lighting control system 100 can change or suggest changes to the remaining parts. Therefore, the user does not need to specify all of the lighting control settings, which simplifies the setting work by the user and reduces the burden on the user.

[0068] In addition, since the user can issue commands in natural language, there is no need for a detailed understanding of difficult setting terms or setting methods, making it possible to provide a lighting control system 100 that is easy for anyone to set up.

[0069] The control device that analyzes the input information and generates the setting contents is not limited to the cloud server 6, but may be the control controller 2, the communication controller 3, the control unit 17, or the controlled power supply 16. In this case, communication with the cloud server 6 via a network does not have to be performed. If the functions of the cloud server 6 are provided in circuits within the lighting fixture 1, such as the control unit 17 or the controlled power supply 16, the lighting control system of this embodiment may be configured as a single lighting fixture. The control device may also be configured from multiple devices. In this case, some of the functions of the control device described above may be realized by one device, and other parts may be realized by other devices.

[0070] Also, the control device only needs to extract a command element from input information in natural language from a user and change a first part of the lighting control setting that corresponds to the command element and a second part related to the first part, and a learning function does not need to be used to change the lighting control setting. For example, in setting the date or time shown in FIG. 15, a learning function by AI does not need to be used.

[0071] Fig. 21 is a functional block diagram of the cloud server 6 according to the embodiment 1. Fig. 22 is a hardware configuration diagram of the cloud server 6 according to the embodiment 1. Here, the configuration of the cloud server 6 will be described as an example of a control device, but the control device may be, for example, the control controller 2, the communication controller 3, the control unit 17, or the control power supply 16.

[0072] In FIG. 21, the receiving unit 6a receives input information in natural language from a user via an input device. The extracting unit 6b extracts a command element and a command type from the input information. The information acquiring unit 6c acquires information for changing the lighting control settings from an acquisition source according to the command type. The setting changing unit 6d changes a first part of the lighting control settings corresponding to the command element and a second part related to the first part based on the acquired information and command element to generate setting contents. The notifying unit 6e notifies the user of the set setting contents.

[0073] The functions of the receiving unit 6a, the extracting unit 6b, the information acquiring unit 6c, the setting changing unit 6d, and the notifying unit 6e are realized by a calculation device such as a processor 6f shown in Fig. 22. The calculation device may be dedicated hardware, or may be a CPU (Central Processing Unit) or a microcomputer that executes a program stored in a memory 6g. The functions of the receiving unit 6a, the extracting unit 6b, the information acquiring unit 6c, the setting changing unit 6d, and the notifying unit 6e may be realized by a plurality of calculation devices.

[0074] The memory 6g stores a program for extracting a command element from input information in natural language from a user and changing a first part of the lighting control setting that corresponds to the command element and a second part related to the first part. The memory 6g is a non-volatile memory or the like. The memory 6g may store a trained model obtained by a training function.

[0075] Furthermore, in the present embodiment, the lighting fixture 1 that emits light to mimic a blue sky has been described as an example, but the type of lighting fixture 1 included in the lighting control system 100 is not limited. Any lighting fixture that can control at least the brightness or the color of light emitted can be adopted as the lighting fixture 1. Furthermore, the lighting control system 100 only needs to have one or a plurality of lighting fixtures 1, and the plurality of lighting fixtures 1 may include different types of lighting fixtures. Furthermore, in the present embodiment, the control system or control device for lighting fixtures has been described as an example, but the control system or control device of the present embodiment may be applied to control not only lighting fixtures, but also air conditioners, video systems, broadcasting systems, and the like.

[0076] The above-mentioned modifications can be appropriately applied to the lighting control systems and control devices according to the following embodiments. Note that the lighting control systems and control devices according to the following embodiments have many points in common with the first embodiment, so the following description will focus on the differences from the first embodiment.

[0077] Embodiment 2 FIG. 23 is a diagram showing an operation flow of lighting control system 100 according to embodiment 2. The configurations of lighting fixture 1 and lighting control system 100 according to the present embodiment are the same as those of embodiment 1. In the present embodiment, the control when changing the lighting control settings is different from that of embodiment 1. In embodiment 1, the setting contents proposed by cloud server 6 were set in controller 2 after approval by the user. In contrast, in the present embodiment, the setting contents proposed by cloud server 6 are set in controller 2 and lighting control system 100 is able to operate in accordance with the setting contents, and then permission from the user is obtained.

[0078] Steps 201 to 213 are basically the same as steps 101 to 113 in the first embodiment. However, this embodiment differs from the first embodiment in that information is acquired from the control controller 2 regardless of the number of inquiries. In step 214, the cloud server 6 generates setting contents using the queried information, similar to step 114 in the first embodiment. In this embodiment, after generating the setting contents, the cloud server 6 issues a command to the control controller 2 based on the setting contents.

[0079] In step 215, the communications controller 3 transmits the received command to the controlling controller 2. In step 216, the controlling controller 2 registers the received setting contents in the lighting control system 100, and notifies the communications controller 3 that the setting contents have been registered. Here, registration of the setting contents indicates that the setting contents have been reflected in the lighting control system 100, and that the lighting control system 100 or the lighting fixture 1 is now in a state where it can operate according to the setting contents. Registration of the setting contents may also indicate that the setting contents have been stored in the controlling controller 2 or the lighting fixture 1.

[0080] In step 217, the communication controller 3 that has received the notification from the control controller 2 transfers the notification to the cloud server 6. In step 218, the cloud server 6 notifies the user of the generated setting contents. If the user does not consent in step 219, the process returns to step 201 in order to further prompt the user about the contents he or she would like to change.

[0081] If the user gives consent in step 219, in step 220, cloud server 6 commands control controller 2 via communication controller 3 to cause lighting fixture 1 to start operating with the settings reflected in step 216. In step 221, control controller 2 starts operating lighting fixture 1 in accordance with the reflected settings. In step 222, control unit 17 in lighting fixture 1 sequentially commands controlled power supply 16 in accordance with the commands of control controller 2. In step 223, controlled power supply 16 operates in accordance with the commands. As a result, lighting fixture 1 operates in accordance with the settings.

[0082] Thus, in this embodiment, the cloud server 6 registers the setting contents obtained by changing the first and second parts of the lighting control settings in the lighting control system 100, and then notifies the user of the setting contents (step 218). If the user does not approve the setting contents, the cloud server 6 again accepts input information in natural language from the user (step 201). The cloud server 6 extracts the command element from the input information accepted again, changes the part of the setting contents that corresponds to the command element and the part related to the part that corresponds to the command element, and registers the changed setting contents in the lighting control system 100 (steps 202 to 215).

[0083] 19, lighting device 1 starts operating in accordance with the settings (step 223) after the user's consent (step 219) is obtained. However, this is not limited thereto, and lighting device 1 may start operating in accordance with the settings at the time the settings are registered in step 216.

[0084] In the first embodiment, the cloud server 6 needs to temporarily store the generated setting contents and then obtain the user's consent. In contrast, in the present embodiment, the cloud server 6 only needs to transmit the generated setting contents to the control controller 2 and register them, regardless of whether the user's consent is obtained or not. If the user's consent is not obtained thereafter, the control controller 2 is again inquired about the current lighting control settings (steps 201 to 213), and setting contents are generated based on the obtained information. For this reason, in the present embodiment, there is no need to keep track of the number of inquiries, and the lighting control system 100 can be operated with a simple control flow.

[0085] The technical features described in each embodiment may be used in appropriate combination.
