LED Circuits and Assemblies

A method for constructing an AC LED lighting element, the method comprising the steps of:

• forming a first branch by connecting a first LED to a second LED in opposing series relationship orientated such that the outputs of each LED form a first junction;
• forming a second branch by connected a third LED to a fourth LED in opposing series relationship orientated such that the inputs of each LED form a second junction;
• forming a first basic circuit by
• connecting the least first and second branches at first and second common points;
• and,
• connecting the first junction and the second with a first cross-connecting circuit branch having at least a fifth LED so that the first, fourth, and fifth LEDs form a closed circuit during one phase of an AC source and the second, third, and fifth LEDs form a closed circuit during a second phase of the AC source;
• and,
• integrating a base with the first basic circuit to facilitate integration with a lighting fixture or system.

An AC LED light element comprising:

• a first basic circuit having LEDs, each LED having an input and an output, and the circuit having at least first and second branches connecting at first and second common points, the common points providing input and output for an AC driving current for the circuit;
• the first branch having at least first and a second LED, and the second branch having at least third and a fourth LED;
• the first LED is connected to the second LED in opposing series relationship with the inputs of the first and second LEDs defining a first branch junction;
• the third LED is connected to the fourth LED in opposing series with the outputs of the third and fourth LEDs defining a second branch junction,
• the first and second branches are connected to one another such that the output of the first LED is connected to the input of the third LED at the first common point and the output of the second LED is connected to the input of the fourth LED at the second common point;
• a first cross-connecting circuit branch having at least a fifth LED, the first cross-connecting circuit branch being configured such that the input of the fifth LED is connected to the second branch junction and the output is connected to the first branch junction;
• and,
• a DC backup supply connected to at least one of the first, second, third, fourth, or fifth LEDs.
