Abstract: An AC-driven LED circuit includes a first circuit having a first branch and a second branch which connect at first and second common point The common points provide input and output for an AC driving current from a driver of the circuit The first branch has first LED and second LED, the first LED being connected to second LED in opposing series relationship with the inputs of the first and second LEDs defining a first branch junction A second branch has a third LED and a fourth LED, the third LED is connected to the fourth LED in opposing series relationship with the outputs of the third and fourth LEDs defining a second branch junction Improvement in performance and scalability is provided by adding n diodes to a given basic circuit and x cross connecting circuit branch diodes and providing one or more basic circuits in series and or basic.
