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