Abstract
An LED string light includes a first conducting wire, a second conducting wire, and a third conducting wire which are arranged in parallel. The first, second, and third conducting wires all comprise a conducting wire core and an insulation layer coating a surface of the conducting wire core, and the first conducting wire and the second conducting wire define a plurality of lamp welding regions. The LED string light also includes a plurality of SMD LEDs respectively disposed at the plurality of lamp welding regions. The first conducting wire is selectively cut off at a plurality of first positions and the second conducting wire is selectively cut off at a plurality of second positions based on whether the plurality of the SMD LEDs are connected in series or in hybrid of series and parallel.
