It should also be noted that, in the case where second, when the first flexible circuit board and the second flexible circuit board are more
When sandwich circuit board, have following characteristics different from the first situation.In order to improve the structural stability of flexible light band；One embodiment party
In formula, for example, referring to Fig. 7, first Braided strap body 210 further includes front insulating layer 211, braiding main line layer 212 and anti-
It insulate respectively with the front insulating layer and the reverse side two opposite sides of face insulating layer 213, the braiding main line layer
Layer fitting setting；Specifically, the braiding main line layer 212 further includes positive litzendraht wire 212a and cathode litzendraht wire 212b, described
Positive litzendraht wire and cathode litzendraht wire are electrically connected with the reverse side line layer respectively.In this way, can protect by the way that insulating film is arranged
Main line is woven, improves the stability of braiding main line, and then improve the structural stability of flexible light band.
It should also be noted that, please referring to Fig. 1 and Fig. 8, the extrusion light bar further includes protection overcoat 500, the protection
It puts on outside and offers accommodating cavity, the extrusion gum cover is in the accommodating cavity body.In this way, by setting protection overcoat,
The structural stability and reliability of light bar can be improved.In addition, by setting protection overcoat, it, can since housing is translucent material
The heat dissipation effect of light bar is effectively ensured, and then it can guarantee the job stability of light bar.And by setting protection overcoat, may be used also
To play the effect of waterproof, the safety of light bar is improved.
The present invention compared with the prior art the advantages of and have the beneficial effect that:
The present invention is a kind of endless low pressure without 360 ° of the pressure drop extrusion light bar that shine, and passes through the front and back in litzendraht wire
The first flexible lamp plate and the second flexible lamp plate is respectively set, may be implemented 360 ° and shine, facilitate carry out using；And by squeezing
Upper jacket and lower jacket are set in jacket out, the first flexible lamp plate and the second flexible lamp plate can be respectively coated by, can also be improved
Its structural stability and reliability.
Only several embodiments of the present invention are expressed for embodiment described above, and the description thereof is more specific and detailed, but
It cannot be construed as a limitation to the scope of the present invention.It should be pointed out that for the ordinary skill people of this field
For member, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to of the invention
Protection scope.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
