Road protective layer.Whether a sandwich circuit layer 2a structures or two-layer structure (a sandwich circuit layer 2a and one dielectric layer 2b) can take
With circuit protecting layer.Circuit protecting layer can also be arranged in a side surface of bendable circuit soft board, such as only with light source
Circuit protecting layer is arranged in 202 side.It should be noted that bendable circuit soft board is a sandwich circuit layer structure 2a or is two layers
Structure (a sandwich circuit layer 2a and one dielectric layer 2b), hence it is evident that (one layer is pressed from both sides in two sandwich circuit layers than general three-layer flexible substrate
Dielectric layer) more flexible and flexibility, therefore, can with the special formed collocation of fluorescent tube 1 (such as:Non- straight lamp),
And bendable circuit soft board is tightly attached on 1 tube wall of fluorescent tube.In addition, it is preferable that bendable circuit soft board, which is tightly attached to tube wall,
Configuration, and the number of plies of bendable circuit soft board is fewer, then heat dissipation effect is better, and material cost is lower, more environmentally friendly, flexible effect
Fruit also has an opportunity to be promoted.
Please continue to refer to Fig. 3, in one embodiment, LED lamp panel 2 is equipped with several LED light sources 202, is equipped in lamp cap 3
