The control signal is generated based on the command content in the selected operation command. However, the control unit 201 may change (adjust) the control signal according to the operation command depending on the function of the luminaire itself. For example, in a lighting fixture having a function of adjusting the signal level of the illumination light such as a hand dimming function and an automatic lighting function, the lighting has a signal level different from the dimming signal level indicated by the dimming signal included in the operation command. It may be a control signal to irradiate light. Here, the signal level indicated by the dimming signal of the operation command is referred to as a dimming signal level, and is referred to as an instrument control signal level of the signal level specified by the control signal actually supplied to the illumination unit 202.

When a control signal for controlling the lighting unit 202 is generated, the control unit 201 controls the lighting unit 202 based on the generated control signal. The control unit 201 maintains the control state of the lighting unit 202 by the generated control signal until it becomes necessary to change the control content such as receiving the next operation command.

Further, the control unit 201 transmits a control state signal indicating the control state of the lighting unit 202 to each of the operating devices 111 to 114 at a predetermined timing. For example, the control unit 201 transmits a control state signal indicating the control state of the lighting unit 202 at a predetermined cycle (for example, a cycle such that the operating devices 111 to 114 can monitor the change in the control state of the lighting unit 202 in real time). do. The control unit 201 can notify the control state to the operation devices 111 to 114 in real time by transmitting the control state signal to the operation devices 111 to 114 at a predetermined cycle. Further, the control unit 201 may transmit a control state signal in response to a request from the operating devices 111 to 114.

When transmitting the control state signal (ST14, YES), the control unit 201 generates a control state signal based on the content of the selected operation command, the control signal supplied to the lighting unit 202, and the like (ST15). For example, the control unit 201 has an operating device that is a source of the selected operation command, a dimming signal level specified by the dimming signal included in the selected operation command, and a control signal that actually controls the lighting unit 202. The instrument control signal level, the operation mode, etc. are specified by, and the control state information including these information is generated.

When the control state information is generated, the control unit 201 transmits the generated control state signal to the operating devices 111 to 114 by the communication unit 203 (ST16). The control unit 201 may generate control state information and store it in a memory or the like each time the control state of the lighting unit 202 changes. In this case, the control unit 201 may transmit the control state information held in the memory at a predetermined timing to the operating devices 111 to 114.

In the above-mentioned operation example, the operation examples of the lighting fixtures 101 to 104 capable of communicating according to the first communication standard have been described, but the lighting fixtures 105 and 106 cannot directly receive the operation command. Therefore, with respect to the luminaires 105 and 106, the intermediate device 122 receives the operation command for the luminaires 105 and 106 from the operating devices 111 to 114 in the first communication standard, and the control state of the luminaires 105 and 106 is reached. The signal is transmitted to each of the operating devices 111 to 114.

For example, the intermediate device 122 receives an operation command for the lighting fixtures 105 and 106 from the operating devices 111 to 115. The intermediate device 122 selects one operation command from a plurality of operation commands for the luminaire 105 (106) using a predetermined operation mode (for example, HTP mode), and uses the selected operation command for the second communication standard. It is supplied to the lighting fixture 105 (106) as a dimming signal.

Further, the lighting fixtures 105 and 106 receive a dimming signal from the intermediate device 122 according to the second communication standard, and control the lighting unit 202 with a control signal based on the dimming signal received from the intermediate device 122. The lighting fixtures 105 and 106 transmit the control signal used for controlling the lighting unit 202 to the intermediate device 122 in the second communication standard.

The intermediate device 122 receives control signals from the luminaires 105 and 106 according to the second communication standard. The intermediate device 122 generates a control state signal in which information indicating the operating device that is the source of the operation command selected for the lighting fixtures 105 and 106 is added to the control signal received from the lighting fixtures 105 and 106. The intermediate device 122 transmits the generated control state signal of the luminaire 105 and the control state signal of the luminaire 105 to the operating devices 111 to 114.

Next, the operation of the operating devices 111 to 114 in the lighting system 100 according to the embodiment will be described.
FIG. 5 is a flowchart for explaining the operation of the operating devices 111 to 114 according to the embodiment.
In each of the operating devices 111 to 114, the operator inputs an operation command for each of the lighting fixtures 101 to 106 using the operating unit 304. The control unit 301 of the operation devices 111 to 114 receives the input of the operation instruction related to the operation such as the dimming instruction to the lighting fixtures 101 to 106 to the operation unit 304. When the operator inputs an operation instruction regarding the operation of the lighting fixtures 101 to 106 using the operation unit 304 (ST31, YES), the control unit 301 generates an operation command according to the content of the operation instruction to the operation unit 304. The generated operation command is transmitted by the communication unit 302.

For example, the operation command includes a DMX address of a target luminaire, a dimming signal that specifies the brightness of the illuminating light, information indicating an operating device that is a transmission source, information such as a universe, and the like. The control unit 301 generates an operation command in a format based on the protocol of the first communication standard (for example, Art-Net, sACC, etc.) from the above-mentioned information. Further, the control unit 301 may generate an operation command including a dimming signal that specifies the light color of the illumination light.
It is also possible to generate an operation command including information specifying the irradiation direction of the illumination light.

Further, the control unit 301 receives the control state information transmitted from the lighting fixtures 101 to 104 or the intermediate device 122 at a predetermined timing by the communication unit 302. When the communication unit 302 receives the control state information (ST33, YES), the control unit 301 stores the received control state information in the storage unit 303 (ST34). The control unit 301 stores the latest control state information for each luminaire in the storage unit 303. For example, the control unit 301 stores the latest control state information in the storage unit 303 by overwriting the control state information of the luminaire each time the control state information of each luminaire is received.

Further, the control unit 301 of the operation devices 111 to 114 receives an instruction by the operator to request the operation unit 304 to display the status screen. Upon receiving the display request of the status screen, the control unit 301 generates display data of the status screen indicating the operating status of the lighting fixtures 101 to 106 based on the control status information of the lighting fixtures (ST36), and the generated display. The status screen is displayed on the display unit 305 according to the data (ST37).

Next, a state screen showing the operating state of each of the lighting fixtures 101 to 106 displayed on the display unit 305 by the operating devices 111 to 114 according to the embodiment will be described.
FIG. 6 is a diagram showing a display example of a state screen showing the operating states of the lighting fixtures 101 to 106 displayed on the display unit 305 by the operating devices 111 to 114 according to the embodiment.
In the state screen shown in FIG. 6, information for identifying each of the lighting fixtures 101 to 106 in the lighting system 100 is displayed in a list. Information for identifying the lighting fixtures 101 to 106 includes, for example, a fixture name, a model, and a fixture ID.

Further, it is assumed that the lighting system 100 controls the lighting fixtures 101 to 106 by using the second communication standard which is a communication standard peculiar to the lighting-related equipment. Therefore, on the status screen, the information related to the second communication standard is displayed in association with the information for identifying the lighting fixtures 101 to 106.

For example, examples of information related to the second communication standard include DMX addresses, universes, and the like. Here, the DMX address is information for specifying (designating) individual lighting fixtures 101 to 106 on the network. The universe is information indicating a group of devices to be controlled. For example, when it is desired to divide the lighting fixture group to be controlled, the universe is set to a different value. In the example shown in FIG. 6, since the universe (“2”) of the “lighting fixture 4” is set to a different value from the universe (“1”) of another lighting fixture, the operating device corresponding to the universe “1”. From this, it is recognized that "lighting fixture 4" has no response.

Further, on the status screen, the command content specified by the operation command from the operating devices 111 to 114 and the control content executed by the lighting fixtures 101 to 106 are displayed for each of the lighting fixtures 101 to 106. In the example shown in FIG. 6, the dimming signal level is displayed as the command content specified by the operation command, and the instrument control signal level is displayed as the actual control content.

The dimming signal level corresponds to the brightness of the illumination light specified by the dimming signal included in the selected actuation command. The fixture control signal level corresponds to the brightness of the illumination light specified by the control signal actually supplied to the lighting unit 202 by the control unit 201 of the lighting fixtures 101 to 106. According to the state screen shown in FIG. 6, the operator can visually recognize at a glance whether or not the command content and the control content match in each luminaire.

As a specific example, in the example shown in FIG. 6, in the “lighting fixture 1”, the dimming signal level is 30% and the fixture control signal level is 30%. With such a display, the operator can visually recognize that the dimming signal level and the control signal level match. Further, with respect to the "lighting fixture 2", the "lighting fixture 5" and the "lighting fixture 6", the operator can visually recognize that the dimming signal level and the control signal level match.

Further, in the "lighting fixture 3", the dimming signal level is 50% and the control signal level is 100%. In this case, the operator can visually recognize that the dimming signal level and the control signal level do not match. The illumination light actually emitted by the lighting unit of the luminaire has a brightness (equipment) different from the brightness (dimming signal level) indicated by the dimming signal by the hand dimming function and the automatic lighting function of the luminaire. It may be the control signal level).

That is, in the lighting fixtures 101 to 104, the command content (dimming signal level) of the operation command selected from the plurality of operation commands received from the plurality of operating devices, and the control unit 201 actually controls the lighting unit 202. The control content (equipment control signal level) of the control signal may not correspond to one-to-one. Even in such a case, according to the state screen shown in FIG. 6, the operator can see not only which operating device the luminaire is controlled by, but also the brightness of the illuminating light specified by the operating device. At a glance, you can check the dimming signal level, which indicates the brightness of the light, and the instrument control signal level, which indicates the actual brightness of the illumination light.

Since the response (control state signal) cannot be received in the "lighting fixture 4", the dimming signal level and the fixture control signal level are not displayed. This is because the universe set in "Lighting fixture 4" is different from "Lighting fixtures 1 to 3, 5, 6", and communication is not possible with an operating device that can communicate with "Lighting fixtures 1 to 3, 5, 6". This is to become. In such a case, the operating device can recognize that the "lighting fixture 4" exists on the network, but communication becomes impossible, so that "no response" is displayed. As a result, the operator can visually recognize that the "lighting fixture 4" is a lighting fixture that cannot be controlled by the operating device.

Further, the items of the command content and the control content displayed on the status screen are not limited to the signal level (brightness of the illumination light) for controlling the illumination light in the lighting fixtures 101 to 106, but are not limited to the command content and the control content. The corresponding item may be displayed. For example, the displayed items include the light color of the illumination light of the lighting fixtures 101 to 106, the posture of the lighting fixtures 101 to 106 (the irradiation direction of the illumination light), the focus position of the lighting fixtures 101 to 106, and the lighting fixtures 101 to 101. The focus direction of 106 and the like can be mentioned.

Further, on the status screen, information indicating the operating device that is the source of the operation command selected by each of the lighting fixtures 101 to 106 is displayed together with the information indicating the operation mode. In the example shown in FIG. 6, each luminaire has priority as an operation mode, an HTP mode for selecting an operation command (dimming signal) having the highest dimming signal level, and an operation command from a preset operating device. It is assumed that one of the selected priority operating device modes is set.

In the example shown in FIG. 6, it is displayed that the operation mode of the "lighting fixture 1" is the "HTP" mode and the selected operation command is from the "operation device 1". With such a display, the operator can visually recognize that the "lighting fixture 1" is operating (controlling the lighting light) in the HTP mode based on the operation command from the operating device 1.
It is displayed that the operation mode of the "lighting fixture 2" is the "priority operation device" mode, and the selected operation command is from the "operation device 2". With such a display, the operator can visually recognize that the "lighting fixture 2" is operating (controlling the illumination light) based on the operation command from the "operating device 2" in the priority operating device mode.

It is displayed that the operation mode of the "lighting fixture 3" is the "HTP" mode, and the selected operation command is from the "operation device 3". With such a display, the operator can visually recognize that the "lighting fixture 3" is operating (controlling the lighting light) in the HTP mode based on the operation command from the "operating device 3".
Since the "lighting fixture 4" has no response (communication is impossible), the operation mode and the operating device that is the source of the selected operation command are not displayed. With such a display, the operator can visually recognize that the "lighting fixture 4" is a lighting fixture that cannot be controlled by the operating device and the operating state cannot be confirmed.

In the "lighting fixture 5", the operation mode by the intermediate device (node) 122 is the "HTP" mode, and the operation command selected by the intermediate device (node) 122 in the HTP mode is from the "operation device 5 (simple operation device)". It is displayed that it is a dimming signal of. With such a display, the operator operates (controls the illumination light) based on the operation command from the "operation device 5 (simple operation device)" selected by the intermediate device 122 in the HTP mode. You can see that you are there.

The operation mode of the "lighting fixture 6" by the intermediate device (node) 122 is the "HTP" mode, and the operation command selected by the intermediate device (node) 122 in the HTP mode is included in the operation command from the "operation device 1". It is displayed that it is a dimming signal. With such a display, the operator visually recognizes that the "lighting fixture 6" operates (controls the lighting light) based on the dimming signal from the "operating device 1" selected by the intermediate device 122 in the HTP mode. can.
