Various embodiments for an LED decorative light string are described herein that generally comprise one or more branch circuits that are parallelly connected with each other, and then connected to a common power supply wire for importing an operational voltage. A given branch circuit comprises a plurality of light groups serially connected in turn. A given light group can include two or more LEDs, wherein at least one LED is parallelly connected with at least one other LED in a reverse direction. The various LED decorative light strings described herein are more economical, more reliable in performance, and have a longer life-span than conventional LED light strings. |
