The flexible lamp area mainly has two types, one is positive bending type flexible lamp area, which has high light efficiency and can be bent positively, but cannot be bent laterally; the other is lateral bending type flexible lamp area, which has low light efficiency and can be bent laterally, but cannot be bent positively. Therefore, neither the positive bending type flexible lamp area nor the lateral bending type flexible lamp area can be bent arbitrarily (not only can be bent laterally, but also can be bent positively), which results in limited application range of each flexible lamp area, and the types of flexible lamp area are various, so that the positive bending type flexible lamp area or the lateral bending type flexible lamp area needs to be produced and selected according to different application scenes, which is quite inconvenient.

It should be noted that the FPC board 31 is a flexible circuit board, which has good deformation performance; the design of the second arc-shaped groove 111 can avoid the light-transmitting part 11 pressing the FPC lamp strip 3 when the lamp strip is bent forward.

[0037] Further, the flexible convex strip 2 is made of transparent or semi-transparent material, which facilitates the user to observe the position of the lamp beads 32 to determine the position that can be cut.
