Wireless communication device and lighting system

A lighting system, comprising:

• a plurality of luminaires;
• a management device which controls operations of the plurality of luminaires;
• a plurality of wireless communication circuits which transmit an operation signal for controlling the plurality of luminaires transmitted from the management device to the plurality of luminaires by performing radio communication;
• and
• a remote controller which transmits an infrared signal to the plurality of wireless communication circuits,
• wherein each of the plurality of wireless communication circuits includes:
• a wired communication circuit which receives, through a wired connection, the operation signal from the management device;
• a radio communication circuit which converts the operation signal received by the wired communication circuit and transmits the converted operation signal to the plurality of luminaires over a radio wave;
• an infrared ray receiver which receives the infrared ray signal transmitted from the remote controller;
• and
• a controller which controls the wired communication circuit, the radio communication circuit, and the infrared ray receiver, and
• wherein when the wired communication circuit receives a signal having a predetermined pattern from the management device, the controller of each of the plurality of wireless communication circuits transitions to a state for receiving the infrared ray signal of the remote controller, and, based on the infrared ray signal transmitted from the remote controller, transmits a signal relating to communication setting between the radio communication circuit and the plurality of luminaires to the plurality of luminaires via the radio communication circuit.
