(Regarding dedicated signals)
In lighting system A, both lighting control signals and dedicated signals are generated according to the DMX-512 standard. The DMX-512 standard generates signals in digital form and can contain 512 control values in one signal.

FIG. 3 shows a waveform diagram of a signal generated according to the DMX-512 standard (hereinafter sometimes referred to as DMX signal). In the DMX-512 standard, a break time is provided at the start position of the signal, during which the LOW state continues for a predetermined time. An 8-bit start code area containing a control value indicating the type of signal is provided after the break time, and a plurality of data areas are provided after the start code area.

The lighting control signal includes predetermined information (eg, "00", "CC", etc.) in the start code area. In addition, the lighting control signal includes control values indicating the mode of the light source 25 of each lighting device 2 in a plurality of data areas. The control value of the light source 25 of which lighting device 2 is included in each data area is predetermined, and the control unit 12 of the controller 1 includes the control value of the corresponding light source 25 in each data area. It generates lighting control signals.

Also, the dedicated signal includes dedicated information (for example, "AA" etc.) different from the predetermined information in the start code area. The dedicated signal contains information about its own operational settings in a plurality of data fields. Which operation settings are included in each data area is determined in advance (for example, the first data area of the dedicated signal includes information about the operation when the lighting control signal is cut off). The signal generator 27 of the instrument 2 generates a dedicated signal containing control values for corresponding operation settings in each data area.

That is, in this lighting system, lighting control signals and dedicated signals are generated according to the same protocol (DMX-512 standard). Moreover, the lighting control signal and the dedicated signal are transmitted and received between the controller 1 and the lighting fixture 2 via the same network 4 . The lighting fixture 2 determines whether the information contained in the start code area of the received DMX signal is the predetermined information or the dedicated information to determine whether the received DMX signal is the lighting control signal or the dedicated signal.

(Lighting system operation)
The operation of this illumination system will be described with reference to FIGS. 1 to 4. FIG. FIG. 4 is a flow chart showing the operation of this lighting system. In FIG. 2, it is assumed that the lighting fixture 2A receives operation settings from the user and transmits a dedicated signal to the lighting fixture 2B.

In step S1, the lighting fixture 2A receives an operation related to operation settings from the user. Specifically, the operation unit 22 of the lighting fixture 2A detects an operation input from the user, and outputs a signal (including information about its own operation settings) corresponding to the user's operation input to the control unit 24. .

In step S2, the lighting fixture 2A performs its own operation settings. Specifically, the setting unit 26 of the lighting device 2A sets the operation of itself (the lighting device 2A) based on the signal input from the operation unit 22 . Also, the setting unit 26 stores its own operation settings in the storage unit 23 .

At step S3, the luminaire 2A generates a dedicated signal indicative of its operational settings. Specifically, when the setting unit 26 sets its own operation, the signal generation unit 27 of the lighting fixture 2A includes dedicated information different from the predetermined information in the start code area and Generating a dedicated signal containing its own operational settings.

In step S4, the lighting fixture 2A transmits the dedicated signal generated by the signal generator 27 to the lighting fixture 2B via the network 4. FIG. Specifically, the communication unit 21 of the lighting fixture 2A receives an input of a dedicated signal from the control unit 24 and outputs the dedicated signal to the network 4. FIG.

At step S5, the lighting fixture 2B receives the dedicated signal. Specifically, the communication unit 21 of the lighting device 2B receives the dedicated signal output from the communication unit 21 of the lighting device 2A via the network 4 . The communication unit 21 of the lighting device 2B outputs the received dedicated signal to the control unit 24 of the lighting device 2B.

In step S6, the lighting fixture 2B sets the operation setting indicated by the dedicated signal as its own operation setting.

With the above configuration, the plurality of lighting fixtures 2 are connected to the same network 4 through which lighting control signals are transmitted from the controller 1 . The lighting device 2A has an operation unit 22 that receives operation settings from the user, a setting unit 26 that sets the operation of itself (the lighting device 2A) according to the operation settings received by the operation unit 22, and the setting unit 26. A signal generation unit 27 for generating a dedicated signal indicating operation settings, and a communication unit 21 for transmitting the dedicated signal generated by the signal generation unit 27 to the network 4 . The lighting fixture 2B includes a communication unit 21 that receives a dedicated signal from the network 4, and a setting unit 26 that sets the operation setting indicated by the dedicated signal as its own operation setting. That is, in the lighting system A, dedicated signals are transmitted and received via the network 4 through which transmission and reception of lighting control signals are performed. Also, the lighting device 2B sets the operation setting indicated by the dedicated signal transmitted from the lighting device 2A as its own operation setting. Therefore, by setting the operation of the lighting device 2A by the user, the operation setting of the lighting device 2B can be the same as the operation setting of the lighting device 2A. Therefore, by setting the operation for one lighting fixture, it is possible to collectively set the operation for the other lighting fixtures, so there is no need to provide a separate device. As a result, it is possible to save the cost of providing a separate device while saving the trouble of setting the same operation for each lighting fixture, so that it is possible to easily set the operation of the lighting fixture in the lighting system.

(Other embodiments)
As described above, the embodiments have been described as examples of the technology disclosed in the present application. However, the technology in the present disclosure is not limited to this, and can also be applied to embodiments in which modifications, replacements, additions, omissions, etc. are made as appropriate.

The above embodiment may be configured as follows.

The lighting device 2A may transmit a dedicated signal indicating its own operation setting to the network 4 when its own operation setting is performed by the setting unit 26 .

Also, the lighting device 2A may be configured to be able to set whether to transmit a dedicated signal. Further, the lighting device 2A may prevent the signal generating section 27 from generating the dedicated signal when the setting is made so that the transmission of the dedicated signal is not performed.

Further, the lighting fixture 2 may be configured to be able to set whether or not to set the operation setting indicated by the dedicated signal as its own operation setting when the lighting fixture 2 receives the dedicated signal. For example, in FIG. 2, the lighting fixture 2B sets the operation setting indicated by the dedicated signal as its own operation setting when the function is ON, that is, when the dedicated signal is received. On the other hand, the lighting fixture 2C does not set the operation setting indicated by the dedicated signal as its own operation setting when the function is turned off, that is, when the dedicated signal is received. As a result, it is possible to deal with the case where there are lighting fixtures, such as permanent lighting fixtures, in the lighting system whose operation settings are not desired to be changed.

Moreover, the lighting device 2 may not include the signal generation unit 27 and the communication unit 21 may not transmit the dedicated signal. That is, the lighting device 2 may have only the function of receiving the dedicated signal without the function of transmitting the dedicated signal among the functions of transmitting and receiving the dedicated signal.

In addition, the communication unit 21 of the lighting device 2 does not have to receive the dedicated signal. That is, the lighting fixture 2 may be provided with only the function of transmitting the dedicated signal without the function of receiving the dedicated signal among the functions of transmitting and receiving the dedicated signal.

Also, the signal generator 27 of the controller 1 may generate the dedicated signal using a protocol other than the DMX-512 standard. However, the signal generator 27 of the controller 1 generates a dedicated signal with the same protocol as the lighting control signal.
