The image sensor 113 then senses the image of the identification signal generating unit 23 in the field of view V ′ and transmits the sensed image to the processing unit 13. After the processing unit 13 recognizes the identification signals ID _A ~ ID _C , ID _E ~ ID _G , and ID _I ~ ID _K in the image, the processing unit 13 controls the transmitting unit 12 to sequentially issue the identification signals ID _A ~ ID. _C , ID _E ~ ID _G , ID _I ~ ID _K , the second wireless control signal Sc ₂ having the same modulation frequency, for example, repeating according to Sc _2A , Sc _2B , Sc _2C , Sc _2E , Sc _2F , Sc _2G , Sc _2I The second wireless control signal Sc _{2 is} issued in sequence of Sc _2J , Sc _2K , wherein Sc _2A represents a second wireless control signal Sc ₂ having the same frequency as the identification signal ID _A ; Sc _2B represents the identification signal ID _B The second wireless control signal Sc ₂ having the same frequency; Sc _2C represents the second wireless control signal Sc ₂ having the same frequency as the identification signal ID _C ; The control circuits 22 of the light source modules 20 _A to 20 _C , 20 _E to 20 _G , and 20 _I to 20 _K control the lighting or extinction of the associated light source 24 after confirming the corresponding second wireless control signal Sc ₂ .

It can be understood that, in the present invention, the frequency at which the processing unit 13 controls the second wireless control signal Sc ₂ emitted by the transmitting unit 12 does not limit the modulation frequency that must be equal to the identification signal ID. In other embodiments, as long as the control circuit 22 is preset to be able to recognize the corresponding frequency, the frequency of the second wireless control signal Sc ₂ emitted by the transmitting unit 12 may not be equal to the modulation frequency of the identification signal ID. . In addition, the order in which the processing unit 13 controls the transmitting unit 12 to issue the second wireless control signal Sc ₂ is merely exemplary and is not intended to limit the present invention.
