Abstract
The LED lighting tube compatible with an electronic ballast has two snubber circuits, a waveform conversion circuit, and at least one LED light string. The snubber circuits are connected to terminals of the LED lighting tube, and input terminals of each snubber circuit are connected to electrode pins of a corresponding terminal. Each snubber circuit has at least one resistor connected in series between the electrode pins of the corresponding terminal. The waveform conversion circuit has multiple rectifier diodes, and input terminals of the waveform conversion circuit are respectively connected to output terminals of the snubber circuits, with a recovery time of each rectifier diode being under 2.5 us. Two ends of the at least one LED light string are respectively connected to output terminals of the waveform conversion circuit, and each one of the at least one LED light string includes multiple LED units connected in series.
