Drive circuit of LED fluorescent lamp

The utility model relates to a drive circuit of an LED fluorescent lamp. The drive circuit comprises an input unit, a rectification filtering unit, an LED constant current drive unit, a detection control unit, an isolation transformer and an LED light source plate. The input unit, the rectification filtering unit, the LED constant current drive unit, and the LED light source plate are sequentially connected; and the detection control unit and the isolation transformer are respectively connected with the LED constant current drive unit. The drive circuit of the LED fluorescent lamp of the utility model does not require adjusting circuits and dismounts devices during interchanging between the LED fluorescent lamp and a conventional electronic ballast fluorescent lamp or a conventional inductance ballast fluorescent lamp, and is simple in structure.
