Abstract:
1. An LED light string comprising: an AC input voltage input having a positive terminal and a negative terminal; parallel conductor wires electrically connected to the positive and negative terminals of the AC voltage input; a front rectification and control circuit defines a full wave rectifier comprising four front rectifying diodes electrically connected to the parallel conductor wires; series conductor wires electrically connected to ends of each of two rectifying diodes of said front rectification and control circuit; a rear rectification and control circuit comprising four rear rectifying diodes electrically connected to the parallel conductor wires; at least one junction box interposed between said front and rear rectification and control circuits, said junction box comprising four junction diodes, a first LED serial set connected between rectifying diodes of the front rectification and control circuit and the first two junction diodes; and a second LED serial set connected between the second two junction diodes and rectifying diodes of the rear rectification and control circuit.
