Abstract: A luminaire includes a light source, a terminal that receives a dimming signal indicating a dimming rate and a parameter signal including a predetermined coefficient, a storage that stores the predetermined coefficient included in the parameter signal received by the terminal, a controller that generates a control value by multiplying information based on the dimming signal received by the terminal by the predetermined coefficient stored in the storage, and a lighting circuit that causes the light source to output light at a brightness in accordance with the control value provided by the controller.

Abstract: When a controller receives an external instruction for initial setting, the controller gives image sensors an instruction regarding lighting. When an image sensor among the image sensors receives the instruction regarding lighting from the controller, the image sensor performs lighting control in accordance with the instruction regarding lighting on a luminaire among luminaires to determine (i) a relative position of the luminaire relative to the image sensor and (ii) a relative position of the image sensor relative to a different image sensor among the image sensors. The controller determines positions of the image sensors and positions of the luminaires by collecting the relative positions of the image sensors and the relative positions of the luminaires determined by the image sensors.
