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 conducting wire, the second conducting wire and the third conducting wire 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 defines 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. Each SMD LED has a first welding leg and a second welding leg, which are respectively welded onto the first welding spot and the second welding spot at one corresponding lamp welding region, and the plurality of the SMD LEDs are connected in parallel. A plurality of encapsulation colloids respectively coat the plurality of the SMD LEDs.
