A linear light-emitting diode (LED)-based solid-state lamp comprises a front-end electric shock detection and control module, an LED driving circuit, and LED arrays. The front-end electric shock detection and control module comprises at least one full-wave rectifier, at least one half-wave rectifier, a constant current sink connected to the at least one half-wave rectifier, a signal extraction unit, a switch control unit, and at least one switch. By sending probing pulses to the constant current sink and checking a detection signal in a mixed direct-current voltage from the at least one full-wave rectifier and the at least one half-wave rectifier in response to the probing pulses, the front-end electric shock detection and control module detects and determines if the linear LED-based solid-state lamp is operated in a normal mode or in an electric shock hazard mode.

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, one or more LED arrays, at least two proximity sensors, and at least two pairs of electrical contacts controlled by the at least two proximity sensors, is used to replace a fluorescent tube or a conventional LED tube lamp. The at least two proximity sensors and the at least two pairs of electrical contacts configured to respectively perform proximity sensing between the two lamp bases and two sockets in an existing lamp fixture are operated by using a low DC voltage. When both two lamp bases are inserted in the two sockets, the at least two pairs of electrical contacts are driven to make an electrical coupling between the full-wave rectifier and the LED driving circuit.

A linear light-emitting diode (LED)-based solid-state lamp comprises an LED driving circuit, LED arrays, at least one rectifier, and an electric current flow control module. The LED driving circuit comprises a control loop compensation device with a control loop correction signal to precisely control an electric current to flow into the LED arrays. The electric current flow control module uses the control loop correction signal in a way that it detects and determines if the linear LED-based solid-state lamp is operated in a normal mode or in an electric shock hazard mode. When an electric shock hazard is identified, the electric current flow control module shuts off a return current flow from the LED arrays to reach the at least one rectifier, thus eliminating an overall through-lamp electric shock current. The scheme can effectively prevent a through-lamp electric shock from occurring during relamping or maintenance.
