Abstract
An LED light string where the parallel connections of additional series blocks of LED lamps are added through an intermediate or junction circuit. The first half of the rectifying diode pair in the junction circuit receive the series connected LED lamps positive connection, complete the rectification of the first rectifying diode pair and couple with the parallel wires of the lighting chain, thus completing the circuit. The second diode pair contained in the junction circuit forms a second, independent circuit by coupling with the lighting chain parallel (AC) wires the join to form the series connection for the subsequent LED lamps connected in series. This circuit is completed by a subsequent junction circuit, or by the diode pair contained in or around the end plug.
