Abstract: The disclosure provides an LED tube lamp, comprising a tube, a terminal adapter circuit, a first rectifying circuit, a filtering circuit, an LED lighting module and an anti-flickering circuit. The tube has a first pin and a second pin for receiving an external driving signal. The terminal adapter circuit has two fuses respectively coupled to the first and second pins. The first rectifying circuit is coupled to the first and second pins for rectifying the external driving signal to generate a rectified signal. The filtering circuit is coupled to the first rectifying circuit for filtering the rectified signal to generate a filtered signal. The LED lighting module is coupled to the filtering circuit and the LED lighting module having a LED module, wherein the LED lighting module is configured to receive the filtered signal and generate a driving signal, and the LED module receives the driving signal and lights. The anti-flickering circuit is coupled between the filtering circuit and the LED lighting module, and is configured such that a current higher than a particular anti-flickering current flows through the anti-flickering circuit when a peak value of the filtered signal is higher than a minimum conduction voltage of the LED module.
