    Abstract: The present invention discloses an LED drive circuit device. The LEDs are installed in a lamp-set and two ends of the lamp-set are provided respectively with two pins to receive a high frequency AC outputted from a ballast, with the two pins being further electrically connected with a drive circuit module. The drive circuit module includes primarily a resonant network correction circuit and a rectifying circuit. The resonant network correction circuit adjusts the high frequency AC received by the two pins to comply with an application range of LED current and then the rectifying circuit converts the AC into a DC which is next outputted through other two pins. By applying the aforementioned circuits, the LED lamp-set can be applied to an ordinary electronic ballast, thereby achieving high compatibility.
