Abstract: A luminaire is provided. The luminaire includes a luminaire body and a first wireless communication device. The first wireless communication device receives a first control signal wirelessly transmitted from an outside of the luminaire body, and wirelessly transmits a second control signal in response to the first control signal. The luminaire body includes: a light source; a second wireless communication device that receives the second control signal; a light emission control circuit that is electrically connected to the second wireless communication device and controls a light emission state of the light source according to the second control signal; and a case that, with or without a cover, houses the second wireless communication device and the light emission control circuit. The first wireless communication device is attached to the luminaire body.

Abstract: A lighting system includes: a plurality of luminaires; a camera which captures an image of an area illuminated by the plurality of luminaires; a sound collector including at least two microphones; and a controller which determines whether or not a sound collected by the sound collector while the plurality of luminaires are off is a sound from a predetermined direction relative to the sound collector. The controller causes at least one of the plurality of luminaires to emit light of a predetermined brightness and activates the camera when the sound collected by the sound collector is determined to be the sound from the predetermined direction, and does not cause the plurality of luminaires to emit light of the predetermined brightness or activate the camera when the sound collected by the sound collector is determined not to be the sound from the predetermined direction.

Abstract: A luminaire is provided that includes a power circuit that supplies power to a light source, an antenna that at least one of transmits and receives a wireless signal, and a metal housing that contains the antenna and the power circuit. The metal housing has an opening, such that the antenna and the opening are arranged to cause a polarization plane of an electric wave most strongly radiated from the antenna, and a polarization plane of an electric wave most strongly radiated from the opening, to substantially coincide with each other.
