Abstract: A thermo-compression head, a soldering system, and a LED tube lamp are disclosed. The thermo-compression head includes a bonding plane, a restraining plane, one or more concave guiding tank, and one or more concave molding tank. The bonding plane is for touching a second object. The restraining plane is adjacent to the bonding plane for touching a first object soldered to the second object. The concave guiding tank is formed on the bonding plane. An end of the concave guiding tank is opened near an edge of the bonding plane while an opposite end of the concave guiding tank is closed. The concave molding tank is formed on the restraining plane and positioned beside the concave guiding tank. The concave molding tank communicates with the concave guiding tank via the open end of the concave guiding tank.

Abstract: A light-emitting diode (LED) tube lamp comprises a lamp tube, a first rectifying circuit, a filtering circuit and an LED driving module. The lamp tube has a first pin and a second pin for receiving an external driving signal. The first rectifying circuit is coupled to the first and second pins, for rectifying the external driving signal to produce a rectified signal. The filtering circuit is coupled to the first rectifying circuit, for filtering the rectified signal to produce a filtered signal. The LED driving module is coupled to the filtering circuit to receive the filtered signal for emitting light. Wherein, the filtering circuit includes a capacitor and an inductor connected in parallel and between one of the first and second pins and the first rectifying circuit, and the parallel-connected capacitor and inductor are configured for presenting a peak equivalent impedance to the external driving signal at a specific frequency.
