Method for controlling streetlight, and control apparatus using same

A method for controlling a streetlight, comprising:

• detecting an existence of an object in a preset detection area by using a motion detect sensor installed in one first node streetlight among a plurality of node streetlights and transmitting a detected object existence signal to a signal processor;
• determining whether the object is a new object that approaches the detection area newly or an existing object that has been detected, when the signal processor receives the object existence signal;
• calculating a size of a lighting zone based on the first node streetlight by using the signal processor when it is determined that the object is the new object in the object-determining;
• inputting the object existence signal and a lighting zone activation signal to a lighting controller installed in the first node streetlight by using the signal processor and inputting a signal regarding the size of the lighting zone to a local area wireless communication unit installed in the first node streetlight;
• setting at least one or more streetlights included in the lighting zone among the plurality of node streetlights adjacent to the first node streetlight as an additional lighting streetlight and transmitting the lighting zone activation signal to the additional lighting streetlight when the local area wireless communication unit receives the signal regarding the size of the lighting zone;
• and
• controlling a dimming value of the first node streetlight according to the object existence signal and the lighting zone activation signal so as to turn on light the first node streetlight when a lighting controller of the first node streetlight receives the object existence signal and the lighting zone activation signal in the signal-inputting and controlling a dimming value of the additional lighting streetlight according to the lighting zone activation signal so as to turn on light the additional lighting streetlight when a lighting controller of the additional lighting streetlight receives the lighting zone activation signal in the communicating.
