[0050] An insulating coating layer 8 is coated outside the core wire 7;

[0051] More specifically, the core wire 7 is a hollow structure 70, which is more conducive to the light enhancement or light mixing effect of the lamp strip;

[0052] As shown in Figure 5 , the Z-type FPCB lamp panel 1 forms a middle part 10 and a bending part 11 at both ends, and at least one side of the middle part 10 and the bending part 11 is provided with a device welding area, wherein at least one LED light source 2 is welded on the device welding area, and a more complex circuit can be designed;

[0053] And a wire welding area 3 is arranged at the corresponding position of the bending part of the Z-type FPCB lamp panel 1, and the two metal wires 61 are respectively welded on a wire welding area 3, so as to realize the connection with the Z-type FPCB lamp panel 1 and realize the power supply to the LED light source 2; in actual application, the Z-type FPCB lamp panel 1 is arranged at the center of symmetry of the cross section of the lamp strip, and the cross section of the lamp strip is circular, elliptical, rectangular or other polygonal.

[0054] The core wire 7 and the insulating coating layer 8 are made of soft silica gel material or soft plastic material, and specifically can use PVC, silica gel, PU and the like, which can be transparent, white or colored plastic materials with light transmission properties.
