LED tube lamp

An LED tube lamp, comprising:

• a tube having a first end and a second end, the first end being opposite to the second end;
• two end caps, separately disposed on the first end and the second end of the tube;
• a power supply module, at least disposed in a receiving space formed by the tube and one of the two end caps, the power supply module comprising a power circuit board having a plurality of electronic components and soldering points disposed thereon, wherein the power circuit board comprises a first surface and a second surface, and the second surface comprises a first zone and a second zone;
• and
• an LED light strip, disposed in the tube, the LED light strip comprising a lamp board and a plurality of LED light sources, wherein the lamp board comprises a freely extending end portion and a lighting portion, wherein the lighting portion is disposed in the tube and the plurality of LED light sources are disposed in the lighting portion, wherein the freely extending end portion connects between the power supply module and the lighting portion, wherein the freely extending end portion forms a folding zone overlapping the second zone of the power circuit board in a radial direction of the tube, whereby the folding zone faces the second zone, and
• wherein a first isolator disposed between the folding zone and the power circuit board,
• wherein a portion of the freely extending end portion located in the folding zone comprises a first bending portion and a second bending portion, the first bending portion is disposed closer to the second surface of the power circuit board than the second bending portion in the radial direction of the lamp body, the first isolator is disposed between the first bending portion and the power circuit board.
