Claim:
1. A linear light-emitting diode (LED) tube lamp, comprising: a housing having two ends; a light-emitting diode printed circuit board (LED PCB), the LED PCB comprising one or more LED arrays disposed thereon; two lamp bases each connected to a respective end of the two ends of the housing, each lamp base comprising a bi-pin each with two pins protruding outwards and configured to connect to an external fixture lamp socket, each lamp base further comprising an input module comprising a shock prevention switch and at least one thermal protection device electrically connected to the bi-pin; and an LED driving circuit configured to convert an input alternating current (AC) voltage from an external power supply into regulated direct current (DC) voltage and current provided to power the one or more LED arrays, wherein, for each lamp base, when either the respective shock prevention switch or the respective at least one thermal protection device is shut off, the input AC voltage is decoupled from the linear LED tube lamp, and wherein, for each lamp base, when the bi-pin is installed in the external fixture lamp socket, and when an electric arc starts between the bi-pin and the external fixture lamp socket and generates heat, the at least one thermal protection device is automatically shut off.
