Firecracker-shaped light string
A firecracker-shaped light string is provided, which relates to a light string technology. A key point of a technical solution is that the firecracker-shaped light string includes a controller for receiving an electric power signal from a power plug and controlling a working state of the firecracker-shaped light string, the power plug connected to the controller, and a triple-wire sheathed light string and three main light strings that are electrically connected to the controller. The three main light strings are enwound into a twisted main body. Each main light string includes a lead wire and equidistant LEDs vertically mounted along the lead wire, and the LEDs on the three twisted main light strings are spaced at equal distances, thus forming a structure of the firecracker-shaped light string.
1 . A firecracker-shaped light string, comprising a controller ( 1 ) for receiving an electric power signal from a power plug ( 2 ) and controlling a working state of the firecracker-shaped light string, the power plug ( 2 ) connected to the controller ( 1 ), and a triple-wire sheathed light string ( 3 ) and three main light strings ( 4 ) that are electrically connected to the controller ( 1 ), wherein the three main light strings ( 4 ) are enwound into a twisted main body; each main light string ( 4 ) comprises a lead wire and equidistant LEDs ( 5 ) vertically mounted along the lead wire, and the LEDs ( 5 ) on the three twisted main light strings ( 4 ) are spaced at equal distances, thus forming a structure of the firecracker-shaped light string; the triple-wire sheathed light string ( 3 ) is enwound in gaps of the main light strings ( 4 ) and comprises three independent lines, and mini LEDs ( 6 ) that are spaced apart on the three independent lines.
2 . The firecracker-shaped light string according to claim 1 , wherein a head end of the triple-wire sheathed light string ( 3 ) and head ends of the three main light strings ( 4 ) are connected to the controller ( 1 ), and a tail end of the triple-wire sheathed light string ( 3 ) and tail ends of the three main light strings ( 4 ) are fixedly connected through a sheath ( 7 ), to prevent dispersion of the firecracker-shaped light string.
3 . The firecracker-shaped light string according to claim 1 , wherein light-emitting directions of adjacent LEDs ( 5 ) on the three main light strings ( 4 ) that are enwound are staggered in 120°, to form a stereoscopic light-emitting effect.
4 . The firecracker-shaped light string according to claim 1 , wherein the triple-wire sheathed light string ( 3 ) is matched with the three main light strings ( 4 ) in length, and the triple-wire sheathed light string ( 3 ) and the three main light strings ( 4 ) are designed to be flexible materials, facilitating adjustment and bending according to a mounting requirement; and the triple-wire sheathed light string ( 3 ) and the three main light strings ( 4 ) are mechanically interlocked when enwound.
5 . The firecracker-shaped light string according to claim 1 , wherein a waterproof structure is arranged at a joint between the lead wire and each LED ( 5 ) of each of the three main light strings ( 4 ); and the waterproof structure comprises a silicone sleeve ( 8 ) and an epoxy resin sealant.
6 . The firecracker-shaped light string according to claim 1 , wherein a distance between the mini LEDs ( 6 ) is 3 to 5 cm; and a distance between adjacent LEDs ( 5 ) on each of the three main light strings ( 4 ) is 5 to 8 cm.
7 . The firecracker-shaped light string according to claim 1 , wherein each of the three main light strings ( 4 ) works independently, and is able to adjust a working mode, comprising but not limited to, a normally on mode and a flickering mode, of each light string according to a need.
8 . The firecracker-shaped light string according to claim 1 , wherein an enwinding ratio of the triple-wire sheathed light string ( 3 ) to the three main light strings ( 4 ) is 1:3, and an enwinding tension is 0.5 to 0.8 N.
