For example, the floor 2 is divided into regions 3-1 to 3-3 and regions 3-6 to 3-4 adjacent to each other in the first direction. Areas 3-1 and 3-6, areas 3-2 and 3-5, and areas 3-3 and 3-4 are arranged so as to be adjacent to each other in the second direction intersecting the first direction. ..

In addition, lighting devices 1-1 to 1-6 are arranged in regions 3-1 to 3-6, respectively. The areas 3-1 to 3-6 correspond to the shooting areas of the camera units 20 (see FIG. 2) of the lighting devices 1-1 to 1-6, respectively. The boundary between the areas 3-1 to 3-6 may be, for example, a physical section due to the arrangement of a wall, a partition, or the like, or may be a virtual section based on the shooting area of the camera unit 20. ..

On the other hand, when the illumination target 5 does not exist (steps S12 and No), and after the transmission unit 42 executes step S13, the reception unit 43 determines whether or not the identification information of the other lighting device 1 has been received. (Step S14). When the identification information is received (steps S14, Yes), the process returns to step S12, and the subsequent processes are repeatedly executed.

On the other hand, when the identification information is not received (step S14, No), the control unit 40 determines whether or not the transmission / reception of the identification information is completed (step S15). If the transmission / reception is not completed (steps S15 and No), the process returns to step S12, and the subsequent processes are repeatedly executed.

Then, when the transmission / reception is completed (steps S15, Yes), the generation unit 44 generates the installation position information 51 based on the order of transmission / reception of the identification information.
