Abstract
A light-emitting diode (LED) tube lamp with overcurrent and/or overvoltage protection capabilities includes a lamp tube, a first rectifying circuit, a filtering circuit, an LED lighting module, and a protection circuit. The lamp tube has pins for receiving an external driving signal. The first rectifying circuit is for rectifying the external driving signal to produce a rectified signal. The filtering circuit is for filtering the rectified signal to produce a filtered signal. The LED lighting module includes an LED module, wherein the LED lighting module is configured to receive the filtered signal to produce a driving signal, and the LED module is for receiving the driving signal for emitting light. The protection circuit is configured to determine whether to enter a protection state, wherein upon entering the protection state, the protection circuit works to limit or restrain the level of the filtered signal.
