Beschreibung
Zusammenfassung:	The invention discloses an AC light-emitting diode (LED) device, comprising a control unit and a plurality of light-emitting diodes (LED). The anode and the cathode of the light-emitting diode (LED) are respectively connected to the control unit, wherein, the light-emitting diodes (LED) are driven by an AC voltage source; the control unit changes the state of connection in series or the state of connection in parallel for the light-emitting diodes (LED) according to the voltage of the AC voltage source, which leads the size of the current flowing through the LEDs to become uniform.
