Zusammenfassung:A luminaire includes an electric light source, a light source driver configured to turn on the light source, and a controller configured to control the light source driver. The controller is configured to control the light source driver to transmit, with a probability lower than 50% at a prescribed time interval, an optical signal with light of the light source as a medium while the light source is in ON. The prescribed time interval is longer than a time period during which the optical signal is transmitted.
