In the step of performing the monitoring operation ( S100 ), the control unit 200 may sequentially perform the monitoring operation for the operating state of each of the plurality of light emitting modules 100 .

For example, in the step of performing the monitoring operation (S100), the controller 200 performs a monitoring operation on the first light emitting module 110 and then performs a monitoring operation on the second light emitting module 120. As a result, the monitoring operation may be sequentially performed on all of the plurality of light emitting modules 100 .
