    摘要： An LED tube lamp having an LED unit is disclosed. The LED tube lamp includes a control circuit that selectively determines whether to perform a first mode or a second mode of lighting operation according to a state of a property of an external driving signal and a switching circuit coupled to the control circuit and the LED unit. When the control circuit determines to perform the first mode of lighting operation, the control circuit controls the second circuit in a manner such that the switching circuit maintains its on state to allow continual current to flow through the LED unit, until the external driving signal is disconnected from the LED tube lamp, and when the control circuit determines to perform the second mode of lighting operation, the control circuit controls the switching circuit in a manner to regulate the continuity of current to flow through the LED unit by alternately turning on and off the switching circuit.

    摘要： An LED tube lamp including an LED module and a power supply module is provided. The LED module is configured to emit light in response to a driving current. The power supply module is electrically connected to the LED module to provide the driving current based on an external driving signal. The power supply module includes a rectifying circuit, a filtering circuit, a driving circuit, a flicker suppression circuit, and an installation detection circuit. The flicker suppression circuit is electrically connected to the LED module, and configured to control a conduction state of a current path passing through the LED module. The installation detection circuit is electrically connected to the flicker suppression circuit, and configured to detect whether a foreign external impedance is electrically connected to the LED tube lamp. When the foreign external impedance is detected, the installation detection circuit disables the flicker suppression circuit to restrict current from flowing through the current path. When the foreign external impedance is not detected, the installation detection circuit enables the flicker suppression circuit to smooth the driving current by controlling the conduction state based on the external driving signal.

    摘要： The fixing structure includes a first structure part and a second structure part. The first structure part is capable of sleeving over an end of the LED tube lamp and engages with the second structure part. The first structure part includes: a receiving opening capable of being inserted by the end of the LED tube lamp; a position through hole penetrating a back wall of the receiving opening, an area of the position through hole on the back wall being smaller than an area of the bottom wall of the receiving opening, the position through hole capable of engaging with a position part on the end of the LED tube lamp; at least two pins disposed on an outer surface of the back wall; and two convex walls disposed on two opposite outer surfaces of the first structure part. Each of the convex wall forms a coupling structure with the first structure part. The second structure part includes a first wall, a second wall, a third wall and a fourth wall. The third wall has a first side, second side, third side and fourth side. The first side is parallel with the third side and the second side is parallel with the fourth side. The first wall connects to the first side of the third wall and is substantially perpendicular with the third wall. The second wall connects to the third side of the third wall and is substantially parallel with the first wall. The fourth wall connects to the second side and is substantially perpendicular with the third wall.
