In the above-mentioned LED lamp tube, a positioning recess is formed at both ends of the rotating groove.

In the above LED light tube, the central angle corresponding to the rotating groove is 90 degrees.

Compared with common LED lamp tubes, the utility model has the beneficial effect that: the lamp holder provided by the LED lamp tube can rotate at a certain angle, and when it is installed on a lamp panel with different lamp holder insertion point orientations, it can be adjusted according to the orientation of the lamp holder insertion point. According to the orientation, the lamp head is rotated to a suitable angle and installed on the lamp panel, which ensures that the LED lamp tube has the largest irradiation surface, so that the LED lamp tube can be applied to lamp panels with different orientations of the socket points of the lamp head.
