An LED device is disclosed. The LED device comprises a first LED light string, a second LED light string, a rectifying module, and a control unit. The control unit generates a driving current flowing through the first LED light string and the second LED light string. The control unit cuts off the driving current when the input signal is between a threshold voltage and a sum voltage.
