Lighting system, controller, operation terminal, and address determining method

A lighting system including luminaires, image sensors which perform lighting control for the luminaires, and a controller which gives the image sensors an instruction regarding lighting of the luminaires, wherein the controller:

• receives an external instruction for initial setting from an external terminal to which map data is inputted, the map data indicating layout of the luminaires, the image sensors, and the controller;
• and
• provides the image sensors with the external instruction regarding lighting,
• when an image sensor among the image sensors receives the external instruction regarding lighting from the controller, the image sensor performs lighting control in accordance with the external instruction regarding lighting on a luminaire among the 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, and 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.

A controller in a lighting system which includes luminaires, image sensors which perform lighting control for the luminaires, and the controller which gives the image sensors an instruction regarding lighting of the luminaires, the controller comprising:

• a communication device;
• and
• a determiner,
• wherein the communication device:
• receives an external instruction for initial setting from an external terminal to which map data is inputted, the map data indicating layout of the luminaires, the image sensors, and the controller;
• and
• provides the image sensors with the external instruction regarding lighting,
• when an image sensor among the image sensors receives the external instruction regarding lighting from the controller, the image sensor performs lighting control in accordance with the external instruction regarding lighting on a luminaire among the 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, and the determiner 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.
