A doorbell system, set and driven by a wireless communication protocol (i.e. Bluetooth (RTM), Wi-Fi (RTM), ZigBee (RTM)), includes at least one doorbell switch 10, a plurality of lamps 11 and an electronic device 12, having a setup module 121 for setting the lamps 11 then generating and storing operation information. The electronic device 12 may be a smartphone or tablet. The doorbell switch 10 has a wireless signal module 101 generating a startup signal when the switch is triggered. The lamps 11 are electrically coupled to one another through each lamps wireless transmission module 111, and to the switch 10 and electronic device 12, and optionally contain buzzers 13. After the lamps 11 receive the startup signal through modules 101, the lamps 11 are driven according to the operation information and/or the startup signal is transmitted to the other remaining lamps 11 by the module 101. The lamps 11 stop transmission of the startup signal if the signal has not been received within a predetermined time (i.e. 2-5 seconds), or if a lamp 11 receives the signal from another lamp more than once. |
