Abstract
An LED light string with single wire. The LED light string includes one wire including a composite wire core, and a plurality of light bodies. The composite wire core is composed of at least one first conductor layer extending in an axial direction of the wire, at least one second conductor layer extending in the axial direction of the wire, and an insulation layer therebetween. The plurality of light bodies arranged spaced away at set intervals along the axial direction of the wire. Each of the light bodies includes at least one patch LED light-emitting part and an encapsulation colloid coated on a surface of the at least one patch LED light-emitting part. A positive electrode and a negative electrode of the at least one patch LED light-emitting part being electrically connected to the at least one first conductor layer and the at least one second conductor layer, respectively.
