LED drivers and lighting systems having a dynamically reconfigurable switching network is disclosed. The lighting system comprises a switching network which provides interconnections between LEDs or LED lamps that can dynamically reconfigure between largely parallel circuits and largely serial circuits as the instantaneous voltage of a power supply varies. When the instantaneous voltage of the power source is low, the switching network interconnects the LED lamps in a largely parallel configuration. As the instantaneous voltage increases, the switching network reconfigures and interconnects the LED lamps with increasing serial configurations. As the instantaneous voltage begins to decrease, the switching network reconfigures and interconnects the LED lamps back to a largely parallel configuration.

Dynamically reconfigurable LED drivers and lighting systems

A solid state lighting driver and system having a total harmonic distortion ('THDi') bypass circuit is disclosed. The solid state driver energizes a solid state lamp having a first lighting segment serially connected to a second lighting segment. The THDi bypass circuit bypasses a first lighting segment and energizes a second lighting segment of LEDs when the driving voltage is low. As a result, the solid state lamp will emit light over a larger portion of the power cycle and will decrease the THDi.

Solid state lighting driver with THDi bypass circuit

An integrated Light Emitting Diode (LED) device including multiple LEDs connected to a circuit board, integrated circuit (IC) drivers connected to the circuit board, and a first alternating current (AC) terminal and a second AC terminal connected to the circuit board.

LED light engine

A lighting apparatus includes a solid state lamp including one or more solid state lighting elements, and a power circuit including a current limiting device electrically connected to the lamp. The current limiting device configured to impose a maximum threshold on the current delivered to the lamp, wherein the current limiting device functions as essentially a constant current source. The lighting apparatus includes a housing for the power circuit and lamp, as a module unit.
