Led string light with branch-trunk structure

An LED string light with a branch-trunk structure, comprising a power supply assembly (1) and a controller(7), wherein:

• the LED string light further comprises multiple wire groups (2), a light source assembly (3) is arranged between every two said wire groups (2), and an end of a first wire group (2) is electrically connected to the power supply assembly (1);
• every two said wire groups (2) are at least partially bent and combined to form a branch-trunk structure (4), wherein every two adjacent wire groups (2) are partially intertwisted into a braided shape that supports the light source assembly (3);
• the LED string light further comprises an insulating sleeve (5), and at least part of the insulating sleeve (5) is disposed around the branch-trunk structure (4);
• the light source assembly (3) comprises a columnar transparent light bead (31), a first pin (32), a second pin (33) and an LED light source (35) packaged in the columnar transparent light bead (31), and the first pin (32) and the second pin (33) are arranged at a same end of the columnar transparent light bead (31) and electrically connected to the LED light source (35);
• and
• each said wire group (2) is at least provided with a wire a (21) and a wire b (22) which are arranged abreast, the wire a (21) and the wire b (22) are provided with insulating protection layers (23), at least one end of the wire a (21) is connected to the first pin (32), and at least one end of the wire b (22) is connected to the second pin (33);
• the controller (7) comprises a shell (71) and a PCB (73), and the PCB (73) is arranged inside the shell (71);
• the controller (7) is connected to the power supply assembly (1);
• one end of the first transmission line (74) and one end of the second transmission line (75) are electrically connected to the PCB (73), the other end of the first transmission line (74) is electrically connected to the wire a (21), and the other end of the second transmission line (75) is electrically connected to the wire b (22).
