LED tube lamp

An LED tube lamp, comprising:

• a glass tube having two ends;
• two end caps respectively attached at the two ends of the glass tube, each of the two end caps comprising a lateral wall and an end wall, the lateral wall being substantially coaxial with the glass tube and connected to the glass tube, the end wall being substantially perpendicular to an axial direction of the lateral wall and connected to an end of the lateral wall away from the glass tube, wherein the end wall comprises an insulating portion made of an insulating material;
• an LED light strip attached to an inner circumferential surface of the glass tube by a glue, wherein at least two first connecting pads are arranged at an end of the LED light strip in one of the two end caps;
• a plurality of LED light sources mounted on the LED light strip;
• and
• a power supply module electrically connected to the LED light strip and configured to drive the plurality of LED light sources, the power supply module comprising a printed circuit board separated from the LED light strip, the printed circuit board comprising a first surface and a second surface opposite to and substantially parallel to the first surface, and the first surface and the second surface of the printed circuit board being substantially parallel with the axial direction of the lateral wall, wherein the power supply module further comprises a plurality of electronic components mounted on the printed circuit board;
• wherein the power supply module comprises a rectifying circuit and a filtering circuit electrically connected to the rectifying circuit, the rectifying circuit has at least two input terminals and is configured to rectify a signal received from the at least two input terminals;
• wherein the power supply module comprises an integrated circuit disposed on the first surface of the printed circuit board, and at least two second connecting pads are arranged on the second surface of the printed circuit board and electrically connected to the at least two first connecting pads, respectively.
