  • Patent number: 7905652
    Abstract: A light-emitting diode (LED) string light includes at least two conductive wires, a plurality of LED units, and a plurality of enclosures. The LED string light is characterized in that each of the LED units has leads inserted perpendicularly into the conductive wires to establish electrical connection therebetween and allow the bottom of the LED unit to abut against ends of the conductive wires. Each of the enclosures has two through holes formed therein for the conductive wires to pass through, respectively, and an upper end provided with an accommodating space for receiving and enclosing a lower portion of the LED unit and part of the conductive wires. Thus, the LED string light can be manufactured easily and efficiently with low labor cost.
