An LED tube lamp to be substituted for a fluorescent lamp includes an LED module 630 for emitting light; a rectifying circuit 510 for rectifying an external driving signal to produce a rectified signal; and a mode determination circuit 590 configured to detect a voltage or frequency or other property of the rectified signal, for selectively determining on performing a first mode or a second mode of lighting according to the state of the property of the rectified signal; wherein when the LED tube lamp performs the first mode of lighting, the mode determination circuit allows continual current to flow through the LED module until the external driving signal is disconnected from the LED tube lamp and when the LED tube lamp performs the second mode of lighting, the mode determination circuit regulates the continuity of current to flow through the LED module. The mode determination circuit is able to identify the type of ballast to which the lamp is connected and respond accordingly.

An LED tube lamp which implements a safety function for protecting a user from electric shock, since it conducts only when both ends thereof have been correctly installed into a lamp socket, includes an installation detection module configured in the LED tube lamp to detect an installation state between the LED tube lamp and the lamp socket. The installation detection module includes: a detection pulse generating module 2540, configured to generate a first pulse signal; a detection result latching circuit 2560, configured to receive and output the first pulse signal; a switch circuit 2580, configured to receive the first pulse signal from the detection result latching circuit and configured to maintain a conductive state of the switch circuit during the first pulse to cause a power loop of the LED tube lamp to be conductive; and a detection determining circuit 2570, configured to detect a first sampling signal on the power loop so as to determine the installation state between the LED tube ...

Light-emitting diode (LED) tube lamp comprises a lamp tube, two end caps, rectifying circuit 510, filtering circuit 520, LED module 530 and installation detection module 2520. The first end cap comprises two external connection terminals, and the second end cap has a third external connection terminal, the external connection terminals configured to receive an external driving signal. The LED module (e.g. fig. 11B) is driven by a filtered signal and is disposed on a power loop of the LED tube lamp. The installation detection module (e.g. fig. 15G) generates a control signal having at least one pulse and temporarily causes current to be conducted in a detection path, allowing detection of an installation state between the lamp and a lamp socket. The rectifying circuit (e.g. fig. 9D) comprises three bridge arms, each coupled to an external connection terminal in parallel such that any two bridge arms form a full-wave rectifier. Also claimed is an LED tube lamp having at least two external ...
