摘要： An isolated configuration dimmer circuit of a light emitting diode (LED) applied to a conventional triac dimmer and a dimmer method are provided. When a dimmer phase angle of the triac dimmer is regulated, a second side winding of a transformer of the isolated configuration produces a pulse width corresponding to a modulated alternating current (AC) voltage, so as to regulate the pulse width of a driving signal output by the second side winding of the transformer. In addition, the dimmer circuit regulates the magnitude of a current flowing through the light emitting diode (LED) according to the pulse width corresponding to the modulated AC voltage. Accordingly, the dimmer circuit regulates the pulse width and the magnitude of the current flowing through the LED according to the dimmer phase angle of the triac dimmer. Therefore, a dimmer range of the LED can be increased.
