Lighting system and control method of said system
View Patent ↗A lighting system includes a plurality of lighting devices and a control unit. Each lighting device is configured to respond to command messages that include an identification code of the lighting device, the command signals being generated by the control unit to set the state of each lighting device. Furthermore, each lighting device is configured, upon receipt of the command signal, to emit an electromagnetic signal, detect electromagnetic signals generated by the other lighting devices, and modify the operating parameters of the corresponding lighting device upon detection of the electromagnetic signal, the control unit having a detection system configured to detect the operating parameters of each lighting device.
1. A lighting system comprising:
a plurality of lighting devices; and
a control unit,
wherein each lighting device is configured to respond to command signals comprising an identification code of the lighting devices, the command signals being generated by said control unit to set a state of each lighting device,
wherein each lighting device is further configured to emit a radio frequency signal, upon receipt of said command signal, and to detect radio frequency signals generated by the other lighting devices without reflecting bodies of the radio frequency signals therebetween, and to modify operating parameters of the corresponding lighting device, upon detection of said radio frequency signal,
wherein said control unit comprises detection means configured to detect operating parameters of each lighting device, and
wherein said detection means consist of current absorption measurement means of the lighting devices.
2. The lighting system according to claim 1 , wherein said lighting devices are electrically connected to each other.
3. A control method of a lighting system configured according to claim 1 , comprising the following steps:
arranging the plurality of lighting devices in an environment;
generating said command signal and sending said command signal to a first lighting device;
causing the first lighting device to generate the radio frequency signal;
setting a receiving state of a second lighting device without reflecting bodies of the radio frequency signal therebetween;
changing the operating parameters of the second lighting device upon detection of the radio frequency signal emitted by the first lighting device, detected by the control unit of the operating parameters of said second lighting device;
identifying a relative position between the first and second lighting devices; and
wherein the detection of the radio frequency signal comprises measuring a current absorption of the lighting device.
4. The control method according to claim 3 , wherein the steps of setting a receiving state, changing the operating parameters, and identifying a relative position are carried out for all the lighting devices except said first lighting device.
5. The control method according to claim 4 , further comprising a step of generating an arrangement map of said lighting devices.
