Similarly, the existing lamp strip can be bent only in one direction, as shown in fig. 2, that is, the FPCB lamp panel 1 'is bent in the up-and-down direction of the horizontal plane, and the bending force of the FPCB lamp panel 1' in the bending direction is equivalent; as shown in fig. 3, if bending occurs in another direction, that is, when such a light strip is used in a horizontal bending mode, the FPCB lamp panel 1' is subjected to different stresses, wherein one side is compressed and the other side is elongated, and although the elastic plastic or silicone 3' can be compressed or stretched, the light strip itself cannot meet the stress of shortening or elongation of the FPCB lamp panel 1', so that the structure of such a wire cannot be used in the bending direction of fig. 2, and when the bending force of the FPCB is large enough, the FPCB may be broken and fail.

Therefore, the lamp strip of the existing strip-shaped FPCB lamp panel has the following defects:

it is generally limited to use with bending in one direction or with custom distance length locations;

it can not realize more have the application field of freely shearing lamp area length requirement to crooked direction or according to the on-the-spot position.

It cannot waterproof itself after shearing.
