When power is supplied to the lighting devices 20a to 20c, the CPU 21 of the lighting devices 20a to 20c has its own unique address, model number, device name, and default dimming level value as shown in FIG. 4 from the memory unit 22. The united packet is called and transmitted from the communication unit 23 at predetermined intervals, and the lighting unit 24 is controlled to be lit with a default dimming level value. The interval at which packets are transmitted from the communication unit 23 is, for example, an interval of 20 ms to 4 s, which is longer than the time required for the CPU to process 11 packets. Here, the device information included in one packet includes at least its own identification information and the default dimming level value, and a mode in which the model number and the device name are not included is also allowed. Further, in addition to the own identification information and the default dimming level value, a model number, a device name, or other information may be added to one packet.

The lighting devices 20a to 20c continue to transmit packets until communication with the control device is established.

Next, the control device 10 is brought close to a distance capable of communicating with the lighting devices 20a to 20c, and an operation of scanning a packet transmitted by the lighting device 20 is accepted through the communication unit 15.

FIG. 5 is an example of a screen displayed on the display unit 17 in order to accept an operation of scanning a packet. As shown in FIG. 5, the CPU 11 displays the scan icon 31 at the lower part of the display unit 17. The scan icon 31 is an icon that accepts a scan operation.

The user taps the scan icon 31 to execute the scan operation.

The CPU 11 has a function of creating a list of the acquired lighting devices 20 and displaying the list on the display unit 17 when receiving a packet including at least its own identification information and the default dimming level value.

Since the lighting device 20 transmits at least its own identification information and the default dimming level value as one packet when power is supplied, the control device 10 collectively acquires the information of the lighting device 20 in one communication. In addition, the initial state of the lighting device 20 can be grasped, and device information necessary for controlling the lighting device 20 can be easily obtained. Therefore, even if the lighting device 20 having a different default dimming level value is installed, the user can grasp the state of the lighting device 20 in a short time by acquiring and displaying the initial state of the lighting device 20 with a small number of transmissions and receptions. Therefore, control becomes easy.

Further, when the packet transmitted from the lighting device 20 includes the model number and the device name, the CPU 11 displays the device name and the device icon on the display unit 17 as shown in FIG.

The device name displays the device name included in the packet. When displaying the device icon, the CPU 11 compares the model number included in the received packet with the device icon corresponding to the model number stored in the ROM 12, and displays the device icon corresponding to the received model number. Display in. Here, since the received model number corresponds to the spotlight, the device icon is an icon representing the spotlight.

In the present embodiment, as shown in FIG. 6, the CPU 11 displays a device icon indicating the model of the lighting device 20, a device name of the lighting device 20, and a table 32 showing a default dimming level value on the display unit 17. ..

In the example shown in FIG. 6, the table 32 has a plurality of cells 33 corresponding to each lighting device, and each cell 33 has an icon indicating the model of the lighting device 20 and a device name of the lighting device 20 as “lighting fixture”. , "100" is displayed as the default dimming level value.

Further, the CPU 11 has a function of establishing communication with the lighting device 20 that has created the list. In the example shown in FIG. 6, the CPU 11 accepts a tap on the cell 33 as an operation for establishing communication with the lighting device 20 displayed by the cell 33. For example, the CPU 11 accepts an operation of establishing communication with the lighting device 20 through the operation unit 16.

When the CPU 11 receives the operation, the CPU 11 transmits a connection request to the lighting device 20 through the communication unit 15 according to the operation. The CPU 11 waits until it receives an ACK response to the connection request from the lighting device 20. The CPU 11 establishes communication with the lighting device 20 by receiving the ACK response.

Here, when the communication between the lighting device 20 and the control device 10 is established, the lighting device 20 stops transmitting the packet.

When communication with the lighting device 20 is established, the control device 10 displays a text box 34, a frame 35a, a frame 35b, an icon 37, and the like on the display unit 17 as shown in FIG.

The text box 34 displays the name of the lighting device 20.

The frame 35a displays the current dimming level value.

The frame 35b displays a default dimming level value.

The icon 37 accepts a dimming level input. For example, the icon 37 includes an icon for increasing the amount of light and an icon for decreasing the amount of light. The icon 37 may also include a meter indicating the dimming level.

For example, when the user changes the amount of light of the lighting device 20, the control device 10 transmits a dimming level change signal to the lighting device 20 by tapping the icon 37 of the display unit 17, and the received lighting device 20 is the lighting unit. The amount of light of 24 is changed.

Next, an operation example of the lighting system 1 will be described.

FIG. 8 is a sequence diagram for explaining an operation example in which the lighting system 1 establishes a connection between the control device 10 and the lighting device 20. For simplification, FIG. 8 shows an operation example of the control device 10, the lighting device 20a, and the lighting device 20b. Further, the lighting device 20a shall include a CPU 21a, a memory unit 22a, a communication unit 23a, a lighting unit 24a, and the like. Further, the lighting device 20b shall include a CPU 21b, a memory unit 22b, a communication unit 23b, a lighting unit 24b, and the like.

First, when power is supplied to the lighting devices 20a and 20b, the CPUs 21a and 21b start transmitting their own unique address, model number, device name and default dimming level value as one packet through the communication units 23a and 23b. (S1).

The CPU 11 of the control device 10, for example, the CPU 11 starts scanning packets through the communication unit 15 based on an operation from the user (S2).

When the scan is started, the CPU 11 creates a list from the model number, the device name, and the default dimming level value included in the received packet and displays it on the display unit 17 (S3).

When displayed on the display unit 17, the CPU 11 transmits a connection request to the lighting devices 20a and 20b through the communication unit 15 (S4).

When the lighting devices 20a and 20b receive a connection request from the control device through the communication units 23a and 23b, the lighting devices 20a and 20b stop transmitting packets (S5).

Then, the ACK response is transmitted to the control device 10 through the communication units 23a and 23b (S6).

When the CPU 11 of the control device 10 receives the ACK response through the communication unit 15, it operates in the connection mode. Further, when the CPUs 21a and 21b of the lighting devices 20a and 20b transmit the ACK response to the control device 10 through the communication unit 15, they operate in the connection mode (S7).

After the connection, the control device 10 enables dimming and on / off control of the lighting devices 20a and 20b. The lighting system 1 establishes communication between the control device 10 and the lighting devices 20a and 20b by the above operation.

As described above, the lighting device 20 transmits its own unique address, model number, device name, and default dimming level value as one packet communication, so that the control device 10 transmits the information of the lighting device 20 once. Since it can be acquired collectively by the communication of the above, the number of transmissions and receptions from the power supply to the lighting device 20 to the creation of the list is small, and the list can be created in a short time. In addition, by displaying the device icon, device name, and default dimming level value in a list, the user can visually grasp the control target even in a place where multiple lighting devices of different models are installed. Since the default dimming level value of the controlled object can be grasped, the user can easily control the lighting device 20. Further, since the control device 10 receives the packets transmitted from the lighting device 20 by scanning and displays them in a list, the lighting device 20 to be controlled can be selected. For example, it is possible not to display the packet in the list by not scanning the packet transmitted from the lighting device 20 which is not the operation target.

Although embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other embodiments, and various omissions, replacements, and changes can be made without departing from the gist of the invention.
