Abstract: The present application provides a light string unit, including: a plurality of light-emitting bodies; and a conducting wire, configured to electrically connect the light-emitting bodies in series, opposite ends of the conducting wire being connected to positive polarity and negative polarity of an external power supply circuit or an external power source, respectively. Wherein, the conducting wire is a high-tensile conducting wire which includes: a conductive core wire; an insulated coating, configured to encapsulate the conductive core wire; and a tensile resistant cord, set inside the insulated coating and set parallelly or twisted with the conductive core wire to enhance the tensile strength of the conducting wire. In the present application, the tensile resistant cord enhances the tensile strength of the conducting wire, and completely reaches or even exceeds the requirement on tensile strength of a conducting wire in the UL 588 criterion and has a simplified structure.

Abstract: A decorative lighting unit for a string-lights, especially for a LED string-lights, comprises: a LED-lamp and a plurality of connection leads. Said decorative lighting unit further comprises a leg-locating block, a LED-lamp holder and a transparent plate with decorative patterns formed therein. Said LED-lamp, transparent plate and leg-locating block are assembled together. Said LED-lamp comprises a lamp head and lamp legs. Said lamp legs pass through the leg-locating block and are inserted into the LED-lamp holder. Said lamp legs are electrically coupled to the connection leads. Compared with conventional technology, the LED string-lights incorporated with the decorative lighting units of the invention make the patterns formed on the plate glowing and thus bring comfortable effect, since the light radiated from the LED-lamp is directed to the transparent plate.
