Further, it is described composition line layer flat conductor by flat metal bar by being machined in subregion shape
Into area is disconnected, LED, which is welded in, to be disconnected area or is connected across on adjacent flat conductor.
Further, the flat conductor of the composition line layer is formed for metal foil by chemical etching process.
Present invention also offers a kind of LED bar graph lamp with above-mentioned folding type flexible circuit board, it is characterised in that：It is described
LED bar graph lamp includes flexible tape light source and is encapsulated in the flexible clad of flexible tape light source periphery, the flexible tape light
Source is arranged on line layer by a plurality of LED and formed.
Further, line layer of the flexible tape light source provided with LED forms the light-emitting area of LED bar graph lamp, institute upward
State both sides or wherein side that power wire layer is located at light-emitting area.
Compared with prior art, beneficial effects of the present invention include：
One, LED exiting surface and the light-emitting area of strip light are consistent, and are existed between power wire layer
Vertical angle, the brightness of strip light was both ensure that, and had been beneficial to the bending of power wire layer again,
Avoid the mouth sealing-off in parallel between circuit board.
Two, flexible circuit board width is narrower, effectively reduces the cross-sectional area of strip light, be easily installed and
Moulding, it is also more attractive.
It is pointed out that implement any product of the present invention and non-required while reach all of above effect.
