A fabric treating machine according to the present invention comprises a connector which is disposed at an outer tub and is connected to a driving part which is disposed at either the center or the off-center position of the connector optionally. Therefore, not only the direct driving motor but the indirect driving motor can be disposed without change of the outer tub and the connector. Because the common use of the outer tub is possible regardless of the connecting method of the driving part, there are the advantages that the cost is reduced and productivity and assembly are improved.

An LED lighting system is provided. The LED lighting system includes a main transformer, a voltage detector, a current controller, a second reference voltage supplier, and a power factor compensation circuit. The main transformer transforms an input signal to supply the transformed input signal to an LED group. The voltage detector supplies a control voltage proportional to a level of an input voltage corresponding to the input signal. The current controller includes a first voltage storage, a negative voltage applier, a second voltage storage, switch, and a current control signal generator. The first voltage storage stores the control voltage supplied from the voltage detector or discharges a stored voltage. The negative voltage applier is connected to the first voltage storage, and connected to a ground to apply the control voltage to the ground when the control voltage is a negative voltage. The second voltage storage is connected to the first voltage storage, and stores the control voltage applied through the first voltage storage or discharges a stored voltage. The switch is connected to the second voltage storage, and activated by a driving signal to apply a ground voltage to the second voltage storage. The current control signal generator generates a current control signal according to a voltage signal and gain of the second voltage storage. The first voltage storage or the second voltage storage supplies the current control signal through the voltage detector. The second reference voltage supplier supplies the second reference voltage when the control signal supplied from the voltage detector is equal to or greater than the second reference voltage. The power factor compensation circuit controls a duty ratio of the driving signal according to a level of the current control signal, and controls a peak value of a primary current in the main transformer according to a level of the second reference voltage.

An input voltage transfer apparatus for an LED lighting system is provided. The input voltage transfer apparatus includes a source voltage storage unit, a zero voltage switching unit, and a nonzero voltage switching unit. The source voltage storage unit stores a source voltage. The zero voltage switching unit turns on according to the source voltage stored in the source voltage storage unit when a zero voltage is inputted. The nonzero voltage switching unit turns on according to a current applied thereto through the zero voltage switching unit when a nonzero voltage is inputted. When the nonzero voltage switching unit is turned on, the source voltage storage unit discharges the stored source voltage.
