摘要： An LED tube lamp and an impedance detection method thereof are provided. The LED tube lamp includes a power supply module comprising an impedance detection controller, configured to perform, before the LED tube lamp being lighted up, an impedance detection to determine whether the LED tube lamp is electrically connected to a foreign external impedance in series. When the LED tube lamp is connected to the foreign external impedance in series, the impedance detection controller causes at least two transient variations to an operating current of the LED tube lamp and limits the operating current of the LED tube lamp to not exceed 5 MIU in root-mean-square (RMS), in which a duration of each transient variation does not exceed 1 millisecond when the impedance detection controller performs the impedance detection.

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： A power supply module is configured to provide, based on an external driving signal, a driving current for driving an LED tube lamp. The power supply module includes a detection path circuit, configured to establish a detection path which is capable of affecting an electrical signal on a power line of the power supply module when the detection path is turned on, and a driving circuit, electrically connected to the detection path circuit, and configured to produce the driving current based on the external driving signal. When the driving circuit is activated by receiving the external driving signal, the driving circuit enters into a first mode to detect whether a foreign external impedance is electrically connected to the LED tube lamp. When the foreign external impedance is detected, the driving circuit remains in the first mode, and when the foreign external impedance is not detected, the driving circuit enters into a second mode to produce the driving current. The driving circuit is further configured to obtain a dimming message from the electrical signal and adjust the magnitude of the driving current according to the dimming message when in the second mode.
