Background

As shown in fig. 1 to 4, a flexible light strip of the prior art is shown. The figure shows a double-layer FPCB lamp panel 1 ', wherein the double-layer FPCB lamp panel 1' is formed by two single-layer FPCB lamp panels 10 'in a back-to-back mode through a welding point 4' or other modes; then, coating a layer of silica gel 3 ' or other high polymer plastics outside the double-layer FPCB lamp panel 1 ', so that light sources on two sides of the double-layer FPCB lamp panel 1 ' emit light, and an LED lamp strip capable of emitting light at 360 degrees is formed;

there are some disadvantages in such LED strips. Specifically, as shown in fig. 3, when the light strip is used in a bent manner, the bending use can be performed only in the direction shown in fig. 3, that is, when the double-layer FPCB lamp panels 1 are displaced on the same vertical plane, the bending use is reasonable for the light strip; however, as shown in fig. 4, if the bending in the other direction (horizontal) occurs, i.e. the bending is not symmetrical, the double-layer FPCB lamp panel 1 will be stressed differently, one side is compressed and the other side is elongated, and when the bending force is large enough, the double-layer FPCB lamp panel 1 will be torn or broken, which may result in product failure.

Therefore, the existing lamp strip using the long strip-shaped double-layer FPCB lamp panel 1 has the following defects:

the bending use can be carried out only in one direction; the product has limited use length; the size of the product is large after the product is formed, the material is wasted, and the cost is high; therefore, the existing LED lamp strip is very limited in application scene, and can not realize more application fields with requirements on bending direction and length.
