By the way, when a lighting fixture is added to an existing lighting system, it is necessary to set a communication address for the added lighting fixture in order to transmit and receive lighting control signals between the controller and the added lighting fixture. In this case, a communication address that is not used by existing lighting fixtures is set for the added lighting fixture.

When the communication address is set by such a setting method, if the existing lighting fixtures include lighting fixtures of the same classification (for example, the same model, installation location, etc.) as the added lighting fixtures, these communication Addresses may be set apart. Since lighting fixtures of the same classification are often subjected to the same control at the same time, if the communication addresses of the lighting fixtures of the same classification are set separately, it becomes difficult to control and manage the lighting fixtures. In particular, in a lighting system with a large number of lighting fixtures, mistakes in setting the lighting fixtures are likely to occur.

The identification information includes a first data portion at a predetermined digit position and a second data portion at a predetermined digit position. The identification information assigning unit sets data in the first data part for a plurality of lighting fixtures to be initially installed so that the identification information is arranged according to the classification of the lighting fixtures when sorted using the first data part as a key. and the identification information in which predetermined data is set is added to the second data part, and the lighting fixture to be added is given to the lighting fixture of the same classification as the lighting fixture in the first data part. The same data as the first data portion of the identification information is set, and the identification information set with data different from the predetermined data is added to the second data portion. The communication address setting unit sorts the identification information assigned to each lighting fixture using the first data section as a key, and sets the communication address of each lighting fixture so that the address order is in the sorted order. .

According to the present invention, in a lighting system in which a plurality of lighting fixtures are controlled by a controller, when lighting fixtures are added to an existing lighting system, the lighting fixtures can be easily controlled and managed.

A communication address setting unit 16 sets a communication address to each of the lighting fixtures 2 and 3 based on the identification information stored in the storage unit 12 .

The communication unit 14 is configured by, for example, an electric circuit or the like, and outputs lighting control signals input from the control unit 13 to the network 4 .

(Configuration of lighting equipment)
The lighting fixtures 2 (2A to 2L) and 3 each include a communication section 21, a storage section 22, a control section 23, and a light source .

The communication unit 21 is configured by, for example, an electric circuit or the like, and receives lighting control signals output from the controller 1 via the network 4 . The communication unit 21 outputs the received lighting control signal to the control unit 23 .

The storage unit 22 is a storage medium including ROM, RAM, HDD, SSD, and the like. Various programs executed by the control unit 23 are stored in the storage unit 22 . In addition, the storage unit 22 stores a communication address set to itself.

The storage unit 22 also stores the setting of the control channel mode. Control channel modes include, for example, a "single-color 1ch mode" that changes the mode of the light source according to one control value included in the illumination control signal, and a mode that changes the mode of the light source according to three control values included in the illumination control signal. "RGB (Red, Green, Blue) 3ch mode" and "IRGBW (Intensity, Red, Green, Blue, White) 5ch mode" that changes the aspect of the light source according to the five control values included in the lighting control signal, etc. is included. The storage unit 22 stores which control channel mode it is set to.

The control unit 23 is composed of, for example, a microcomputer including a CPU and a semiconductor memory.

The light source 24 is composed of, for example, a halogen lamp, a fluorescent lamp, an LED, or the like. The light source 24 includes, for example, red, green, and blue light emitting elements, or red, green, blue, and white light emitting elements.

(Regarding lighting control signals)
In the lighting system A, the controller 13 of the controller 1 generates lighting control signals according to the DMX-512 standard. The DMX-512 standard generates lighting control signals in digital form and can contain 512 data areas (channels) in one lighting control signal. The lighting control signal contains one control value in each data field.

Here, the communication addresses of the lighting fixtures 2 and 3 are stored in the storage section 12 . This communication address indicates the data area containing the control values of the lighting fixtures 2 and 3 in the lighting control signal. For example, when the communication address of the lighting fixture 2A is set to "1", the controller 13 generates a lighting control signal including the control value of the lighting fixture 2A in the first data area. That is, the control section 13 generates the lighting control signal according to the communication address stored in the storage section 12 .

Also, the lighting fixtures 2 and 3 require different control values to change the mode of the light source 24 depending on the set control channel mode. Therefore, the setting information of the control channel mode is stored in the storage unit 12 . This control channel mode setting information indicates the control channel mode set for each of the lighting fixtures 2 and 3 . The communication address setting unit 16 sets the communication address according to the control channel mode setting information stored in the storage unit 12 .

For example, when the lighting fixture 2A is set to the "single-color 1ch mode", the communication address setting unit 16 sets a communication address indicating one data area to the lighting fixture 2A. Further, when the lighting fixture 2E is set to the "RGB 3ch mode", the communication address setting unit 16 sets communication addresses indicating three data areas to the lighting fixture 2E.

(How to set the communication address)
FIG. 3 is a diagram showing an example of correspondence between lighting fixtures and communication addresses. As shown in FIG. 3, the lighting fixtures 2A to 2L and 3 are respectively set with a control channel mode, identification information, an automatic address setting function, and a communication address. The address automatic setting function will be described later.
