FIG. 1 is a diagram illustrating a lighting system 10 according to an example of an embodiment. The lighting system 10 includes a lighting fixture 12, a plurality of lighting fixtures 12 and 14 including a plurality of lighting fixtures 14, and a plurality of terminal devices 30 and 40. The plurality of terminal devices 30, 40 include a first terminal device 30 and a second terminal device 40. The number of lighting fixtures included in the lighting system 10 is not particularly limited. Each of the plurality of lighting fixtures 12 and 14 is, for example, a ceiling light. The lighting fixture may be another type such as a downlight or a spotlight. The plurality of lighting fixtures 12 and 14 are capable of wireless communication with each other.

The lighting fixture 12 is connected to the first terminal device 30 operated by the user so as to be capable of wireless communication. When the first terminal device 30 is operated by the user, the lighting fixture 12 receives an operation signal according to the operation. Specifically, the lighting fixture 12 and the first terminal device 30 are transmitted and received by data communication using a bridge connection. The bridge connection establishes a virtual dedicated communication path between the first terminal device 30 and the lighting fixture 12, and uses the communication path to connect different network segments to each other by software processing or a hardware bridge device. , A method of connecting as the same network segment. The bridge connection establishes a virtual dedicated communication path with low possibility of signal transmission/reception failure. The communication through the dedicated communication path is highly reliable because the communication is performed while confirming that the signal has arrived at the other party who has transmitted the signal. For example, in communication using a dedicated communication path, data is always transmitted at predetermined intervals, and even when there is no data to be transmitted, data in a data format called Empty PDU (Protocol Data Unit) is transmitted, and mutual communication is performed. To maintain. If there is data to be transmitted, the data is transmitted through a predetermined communication protocol while communicating at a predetermined interval. If no reply is received during the interval period, the data is retransmitted.

The luminaire 12 or the luminaire 14 is wirelessly connected to the second terminal device 40 operated by another user. At this time, the luminaire 12 or the luminaire 14 is transmitted/received by data communication using the bridge connection similarly to the first terminal device 30.

The wireless mesh network is a communication network formed in a mesh shape by connecting a plurality of devices having a wireless communication function to each other so as to be able to transmit and receive signals. On a wireless mesh network, signals are transferred via one or more devices. As a result, the signal received from the outside by one device on the wireless mesh network can be received by other devices.

The first terminal device 30 and the lighting fixture 12 are communicatively connected to each other by wireless communication of BLE (Bluetooth (registered trademark) Low Energy). The plurality of lighting fixtures 12 and 14 are also communicably connected by BLE wireless communication. For example, the plurality of lighting fixtures 12 and 14 transmit the operation signal by the BLE advertisement signal. The advertise signal is a signal used for periodically transmitting data to notify surrounding devices of the presence of the own device. A fixture ID is set for each of the plurality of lighting fixtures 12 and 14, and by transmitting a signal including the destination fixture ID, the destination lighting fixtures 12 and 14 receive the received signal as their own ID. If included, the signal may be read to control the lighting state of the luminaire 12, 14 or may be transferred to another luminaire 12, 14. In FIG. 1, the numbers 1 to 4 attached to the respective lighting fixtures 12 and 14 indicate the respective fixture IDs. Also, before the first terminal device 30 transmits a signal for bridge connection, the plurality of lighting devices 12, 14 transmit an advertisement signal, and the first terminal device 30 transmits radio waves from the plurality of lighting devices 12, 14.

When receiving the operation signal, the lighting fixture that is the operation target of the operation signal returns a reception confirmation signal indicating that the signal has been received, to the terminal device 30. The reception confirmation signal includes the lighting state (for example, lighting ON) after the operation of the lighting device to be operated. For example, in FIG. 1, arrows in which circle numerals 1, 2, and 3 are attached indicate communication orders. As indicated by a white arrow 1, an operation signal may be transmitted from the first terminal device 30 to the lighting device 12 through a bridge connection. In the example of FIG. 1, the operation signal indicates a case in which the lighting device 14 having the ID 2 is instructed to be turned on. Hereinafter, the luminaire 14 having the ID 2 may be referred to as the target luminaire 14. In this case, as indicated by the thin solid arrow 2, the operation signal is transferred between the plurality of lighting devices 12 and 14 on the wireless mesh network M, and the target lighting device 14 receives the operation signal.
