LED tube lamp

An LED tube lamp, comprising:

• a glass tube;
• two end caps, each of the two end caps coupled to a respective end of the glass tube;
• an LED light strip attached to an inner circumferential surface of the glass tube;
• a plurality of LED light sources mounted on the LED light strip;
• at least two first soldering pads arranged at one end of the LED light strip;
• at least two through holes in the LED light strip, each of the two through holes penetrating the respective first soldering pad and the LED light strip;
• a protective layer disposed on a surface of the LED light strip, the protective layer comprising at least two first opening to expose the two first soldering pads;
• and
• a power supply module comprising a printed circuit board and configured to drive the plurality of LED light sources, the printed circuit board comprising at least two second soldering pads, one of the two first soldering pads soldered to one of the respective second soldering pads by a solder,
• wherein the power supply module at least comprises a rectifying circuit and a filtering circuit coupled to the rectifying circuit, and the solder is disposed on one of the two first soldering pads, one of the respective second soldering pads and in one of the respective through holes.
