Abstract: An LED tube lamp having an end cap and a lamp tube is disclosed. The end cap includes an electrically insulating tubular part, sleeved with an end of the lamp tube, and a magnetic metal object disposed between an inner circumferential surface of the electrically insulating tubular part and the end of lamp tube. The electrically insulating tubular part having an inner circumferential surface with a plurality of protruding portions formed thereon and extending inwardly in a radial direction of the electrically insulating tubular part. Each of the protruding portions is disposed between an outer circumferential surface of the magnetic metal member and the inner circumferential surface of the electrically insulating tubular part, thereby forming a space therebetween, in which a hot melt adhesive is filled so that the end cap and the end of the lamp tube are adhesively bonded.

Abstract: A smart radio system includes a mobile device and a radio device. The mobile device includes a signal processing module for processing a received signal to be outputted as a processed result or processing signals generated by a signal source to be a transmission signal; a user interface for generating a control signal; and a first transmission module for receiving the received signal to be transmitted to the signal processing module or outputting the transmission signal according to the control signal. The radio device includes a real-time communication module for receiving the received signal or transmitting the transmission signal via wireless transmission; and a second transmission module for transmitting the transmission signal outputted by the first transmission module to the real-time communication module or transmitting the received signal received by the real-time communication module to the first transmission module.
