1. An LED tube lamp, comprising:
a glass lamp tube;
an LED light strip disposed inside the glass lamp tube and comprising a mounting region and a connecting region;
an LED module comprising a plurality of LED light sources mounted on the mounting region;
two first connecting pads arranged on the connecting region, each of the first connecting pads comprising a through hole therein;
a fixing structure disposed inside the glass lamp tube and extending along the longitudinal direction of the glass lamp tube, the fixing structure comprising a first end fixedly connected to the inner circumferential surface of the glass lamp tube and a second end fixedly connected to the LED light strip;
a circuit board separate from the LED light strip and soldered to the LED light strip via the two first connecting pads, and a solder disposed on each of the first connecting pads and in the through hole of each first connecting pad; and
a power supply module comprising
a first rectifying circuit coupled to a first pin and a second pin, which are coupled to a first end of the glass lamp tube, and configured to rectify an external driving signal to produce a rectified signal;
a filtering circuit coupled to the first rectifying circuit and configured to filter the rectified signal to produce a filtered signal; and
a driving circuit coupled to the filtering circuit, and configured to receive the filtered signal and drive the LED module to emit light when performing a first driving mode,
wherein when performing the first driving mode, the external driving signal is transmitted through the first and second pins,
wherein the LED light strip further comprises a wiring layer, and the plurality of LED light sources are mounted on the wiring layer, and
wherein the LED light strip further comprises a protection layer disposed on a surface of the wiring layer and the plurality of LED light sources are mounted on the surface of the wiring layer.
