Description

The FPC light-emitting device that multi-directionally is crooked
Technical field
The utility model relates to the substrate field that is provided with LED lamp and circuit, particularly the FPC light-emitting device of cocoa multi-directional bending.
Background technology
Because light is combined with clothes and can finely set off clothing popularity by contrast, enrich clothing color, increase the stylishness of clothes.
Existing light normally adopts the LED lamp as light source the pattern contour on the clothes; Each LED lamp and a circuit board (PCB) that is provided with control circuit are fixing; Connect through flexible wire between each circuit board, make the LED lamp on each circuit board can connect into a string.Though but this structure light-emitting device can sketch the contours of the pattern contour on the clothes, the thickness of each circuit board is bigger on the one hand, causes its volume big; This structure light-emitting device is adding man-hour on the other hand, and it needs manual work respectively two circuit boards to be welded through flexible wire, when the LED lamp is color light source, needs three leads of welding, and it is low to lead system production efficiency; Behind this light-emitting device and the garment-holding,, cause clothes to lose flexibility simultaneously because circuit board can't be crooked.
The utility model content
The technical problem that the utility model mainly solves provides crooked FPC (the Flexible Printed Circuit of a kind of multi-directionally; Flexible print circuit) light-emitting device; The inefficiency that volume was big and the welding lead operation is produced when this FPC light-emitting device can be avoided adopting pcb board as substrate; Make this FPC light-emitting device have suppleness preferably at a plurality of direction free bends.
In order to address the above problem; The utility model provides a kind of multi-directionally crooked FPC light-emitting device; This FPC light-emitting device comprises at least two FPC circuit boards; Between these two FPC circuit boards, be provided with the FPC connecting line with FPC circuit board one at least, on this FPC circuit board, be provided with the LED lamp that is connected with control circuit.
Preferably, the width of said FPC connecting line is the width 1/6-1/4 of FPC circuit board.
Preferably, said FPC light-emitting device is provided with the protective layer of flexibility and printing opacity, and it is identical with the FPC circuit board that this protective layer is.
The FPC circuit board that the utility model multi-directionally is crooked; This FPC light-emitting device comprises at least two FPC circuit boards; Between these two FPC circuit boards, be provided with the FPC connecting line with FPC circuit board one at least, on this FPC circuit board, be provided with the LED lamp that is connected with control circuit.Compared with prior art,, can reduce the thickness of this light-emitting device, and then make the volume of light-emitting device reduce owing to adopt the FPC circuit board as substrate.Between two adjacent FPC circuit boards, be connected simultaneously through FPC connecting line with this FPC circuit board one; Make that the FPC light-emitting device can be flexible in a plurality of directions; Can keep good flexibility, and the FPC circuit board is one-body molded with the FPC connecting line, need the FPC circuit board do not coupled together through welding; Reduce production technology, enhance productivity.
Description of drawings
Fig. 1 is the crooked FPC light-emitting device one embodiment sketch map of the utility model multi-directionally;
Fig. 2 is the utility model FPC light-emitting device embodiment schematic side view;
Fig. 3 is crooked another embodiment sketch map of FPC light-emitting device of the utility model multi-directionally.
Below in conjunction with embodiment, and with reference to accompanying drawing, realization, functional characteristics and the advantage of the utility model purpose is described further.
The specific embodiment
As depicted in figs. 1 and 2, the utility model provides a kind of multi-directionally crooked FPC light-emitting device embodiment.
This FPC light-emitting device comprises two FPC circuit boards 1; Between these two FPC circuit boards 1, be provided with FPC connecting line 2 with FPC circuit board 1 one; On this FPC circuit board 1, be provided with the LED lamp 3 that is connected with control circuit; Wherein, said FPC connecting line 2 is meant and adopts the FPC that is provided with electric conductor as the connecting line that connects FPC circuit board 1.
Specifically, said FPC circuit board 1 is provided with the LED control circuit, and the control circuit that said FPC connecting line 2 will be controlled LED work is electrically connected, and uses between the control circuit and forms electric connection.
Owing to adopt FPC circuit board 1, can reduce the thickness of this light-emitting device, and then make the volume of light-emitting device reduce as substrate.Between two adjacent FPC circuit boards 1, be connected simultaneously through FPC connecting line 2 with this FPC circuit board 1 one; Make the FPC light-emitting device can keep good flexibility; And FPC circuit board 1 is one-body molded with FPC connecting line 2; Need FPC circuit board 1 not coupled together, reduce production technology, enhance productivity through welding.Simultaneously because said FPC connecting line 2 width are less, and this light-emitting device can have certain bendability on the B direction, this FPC connecting line 2 can free bend in the A direction simultaneously, thereby this light-emitting device can be at a plurality of direction free bends.
In the present embodiment, said FPC circuit board 1 is two also can establish three or more as required, and each FPC circuit board 1 is connected with another FPC circuit board 1 through the FPC connecting line.The width of said FPC connecting line 2 is the width 1/6-1/4 of FPC circuit board, can be so that this light-emitting device has flexibility on a plurality of directions.
Of Fig. 3; Said FPC circuit board 1 forms breach with FPC connecting line 2; This breach makes at least one side integral body of light-emitting device be continuous zigzag or wavy; Be to form between said FPC circuit board and the FPC connecting line to make at least one side of light-emitting device be sawtooth or wave structure, its principle is same as the previously described embodiments, repeats no more.
As required; Can on said FPC light-emitting device, be provided with the protective layer of flexibility and printing opacity; It is identical with the sawtooth or the wave structure that are made up of said FPC connecting line and FPC circuit board that this protective layer is, and this protective layer can be protected LED lamp 3, prolongs its service life.
The above is merely the preferred embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
