Abstract: An LED tube lamp includes a lamp tube, a first external connection terminal and a second external connection terminal coupled to the lamp tube and for receiving an external driving signal; an LED lighting module coupled to the first external connection terminal and configured to receive a signal for emitting light, the signal derived from the first external driving signal; and a ballast interface circuit coupled between the first external connection terminal and the LED lighting module. The ballast interface circuit may be configured such that when the external driving signal is initially input at the first external connection terminal and second external connection terminal, the ballast interface circuit will initially be in an open-circuit state, which prevents the LED tube lamp from emitting light, until the ballast interface circuit enters a conduction state, which conduction state allows a current input at the first external connection terminal/second external connection terminal to flow through the LED lighting module and thereby allows the LED tube lamp to emit light
