Abstract
An LED tube lamp is provided herein, which implements the safety function for protecting the user from electric shock since it conducts only when both ends thereof have been correctly installed into a lamp socket. The LED tube lamp 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, configured to generate a first pulse signal; a detection result latching circuit, configured to receive and output the first pulse signal; a switch circuit, 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, configured to detect a first sampling signal on the power loop so as to determine the installation state between the LED tube lamp and the lamp socket.
