Abstract:
A linear light-emitting diode (LED) lamp comprising a housing, two lamp bases at two ends of the housing, a full-wave rectifier, an LED driving circuit, LED arrays, two displacement sensors, and two pairs of electrical contacts controlled by the two displacement sensors, is used to replace a fluorescent tube or a conventional LED tube lamp. The two displacement sensors and the two pairs of electrical contacts are configured to respectively perform position sensing for electric shock hazards. The two pairs of electrical contacts are operated by using a low direct current (DC) voltage supplied by a power sustaining device. When both two lamp bases are inserted in the two sockets, the two pairs of electrical contacts are driven to make an electric connection from the power sustaining device to a low voltage input of the LED driving circuit and to power the LED driving circuit. Use of the low DC voltage is to eliminate electric arcing that may cause internal fire when used with ballasts and to prevent substantial electric shock current from reaching ground through a person's body when used with AC mains.

Claim (Index 1):
A linear light-emitting diode (LED) tube lamp, comprising:\n a housing having two ends; two lamp bases respectively connected to the two ends of the housing, each lamp base comprising a displacement sensor, at least one pair of electrical contacts controlled by the displacement sensor, and at least one electrical conductor configured to connect to a lamp fixture socket that is wired to connect to either alternate current (AC) mains or ballasts; a full-wave rectifier connected to the at least one electrical conductor in each lamp base and configured to convert an input AC voltage of either the AC mains or the ballasts into a direct current (DC) voltage; at least one LED printed circuit board (LED PCB) disposed between the two ends of the housing; one or more LED arrays disposed on the at least one LED PCB; and an LED driving circuit comprising an input filter, a power sustaining device, a driver comprising a voltage feedback module and a low voltage input, one or more start-up resistors connected in parallel with the voltage feedback module, and an electrical jumper pair, the one or more start-up resistors and the voltage feedback module configured to provide a low DC voltage to couple to the power sustaining device via the electrical jumper pair and to sustain operation of the LED driving circuit; wherein:\n the at least one pair of electrical contacts in each of the two lamp bases are connected in series and further connected to the electrical jumper pair so as to loop between the power sustaining device and the low voltage input of the driver; \n when either one of the at least one pair of electrical contacts is not electrically connected, a through-lamp electric shock current does not flow out of the one or more LED arrays; \n when one of the at least one electrical conductor in one of the two lamp bases is inserted into the respective lamp fixture socket while the other one of the at least one electrical conductor in the other one of the two lamp bases is removed from the respective lamp fixture socket and touches an electrically-conductive object, the LED driving circuit stops to operate without delay, free of electric shock current flowing to the electrically-conductive object, and free of electric arc generated on the respective one pair of electrical contacts; and \n when the at least one electrical conductor in each of the two lamp bases is inserted into the lamp fixture socket, the at least one pair of electrical contacts are actuated by the displacement sensor in each lamp base to deliver the low DC voltage from the power sustaining device to the driver, thereby operating the driver and powering the one or more LED arrays.
