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 2):
The linear LED tube lamp of  claim 1 , wherein the driver further comprises a high voltage input configured to receive a filtered DC voltage from the input filter, a power factor correction (PFC) and control device, a switch controlled by the PFC and control device, a current sensing resistor, a diode, an inductor with current charging and discharging controlled by the switch, a resistor, and an output capacitor in parallel with the resistor and connected to the inductor to build up an output voltage and to power the one or more LED arrays, wherein the voltage feedback module is coupled to draw partial power from the output voltage to sustain an operation of the PFC and control device, and wherein, responsive to detecting zero current in the inductor within an AC cycle of the input voltage, the PFC and control device generates a zero current detection signal to control the switch turning on and off.
