Claim:
1. A light-emitting diode (LED) tube lamp, comprising: a lamp tube; a first end cap, having a first external connection terminal and a second external connection terminal and coupled to one end of the lamp tube, a second end cap, having a third external connection terminal and coupled to the other end of the lamp tube, wherein the external connection terminals of the two end caps are for receiving an external driving signal; a rectifying circuit, coupled to the external connection terminals of the end caps, for rectifying the external driving signal to produce a rectified signal; a filtering circuit, coupled to the rectifying circuit, for filtering the rectified signal to produce a filtered signal; an LED module, disposed on a power loop of the LED tube lamp, coupled to the filtering circuit and configured to be driven based on the filtered signal for emitting light; and an installation detection module, coupled to the power loop and configured to generate a control signal having at least one pulse and to temporarily cause a current to be conducted in a detection path during the pulse-on time of the control signal for detecting an installation state between the LED tube lamp and a lamp socket, wherein the rectifying circuit comprises:
