A lighting system includes an LED downlight mountable to a ceiling, a driver, and an insulation displacement connector (IDC). Light from the downlight can be faced downward to project light or upward to reflect light off of the ceiling. The driver has an input with a first voltage and an output with a second voltage, the second voltage being lower than the first and being provided through a wire system extending from the LED driver. The IDC connects the downlight to the wire system. The lighting system can be changed from a first to a second configuration by at least one of adding an additional downlight using a corresponding MC or removing an existing downlight using a corresponding IDC. The second configuration does not significantly affect a desired output range of light from any downlight or any LED circuit of any downlight that remains or preexists from the first configuration.

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.

A light-emitting diode (LED)-based solid-state lamp (LED lamp) comprising four input ports, two bridge rectifiers, two interface modules, an LED driving circuit, and LED arrays operates normally for an input voltage applied from any two of the input ports without operational uncertainty and a fire hazard. The LED driving circuit is configured to provide a regulated power and current to drive the LED arrays. With a cycle-by-cycle triac switching and current control, an over-rated surge current is limited, preventing any fire hazards possibly occurred in the ballast when operated with the LED lamp. With various electrical connection terminals, the lamp can fit and operate in various lamp fixtures comprising two-pin, four-pin, or Edison-base sockets.
