The specific embodiment

In order to further specify the utility model structure, be described in detail below in conjunction with accompanying drawing.

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the utility model discloses a kind of ultrathin flexible lamp band, the a plurality of lamp strings 20 that comprise flexible heart yearn 1, are installed in the heart yearn 1 cover the flexible transparent covering 3 that is used for seal lamps string 20 on above-mentioned heart yearn 1 exiting surface, described heart yearn 1 back side also is provided with one deck insulating protective layer 11, described lamp string 20 comprises a plurality of paster LEDs 2 that connect by conductor wire 7, and described lamp string 20 also is in series with current-limiting resistance 6; Described heart yearn 1 is provided with the transverse holes 4 of a plurality of ccontaining paster LEDs 2, and described a plurality of paster LEDs 2 are installed in respectively in the transverse holes 4; Described heart yearn 1 both sides are provided with first, second

main power line

51,52, and described a plurality of lamp strings 20 are connected in parallel to first,

second power line

51,52, as shown in Figure 6; Described flexible transparent covering 3 also is provided with attaching plug 8 and the power supply extension connector 9 that is electrically connected with described first,

second power line

51,52 with the head end and the tail end of insulating protective layer; Power supply extension connector 9 can be that female joint is male joint also, is connected with the charged gas of the lamp of next unit with convenient, as shown in Figure 7.

Because the utility model adopts power line to replace traditional flexible PCB, and adopt the less paster LED of thickness as light source, only on the exiting surface of heart yearn, cover the very thin flexible transparent covering of one deck simultaneously, make flexible light band of the present utility model very thin, general thickness is between 2mm to 6mm, and therefore ultrathin flexible lamp band pliability of the present utility model is good, is difficult for fracture damage, be convenient to the various bending mouldings of lamp band, simultaneously long service life.

For the ease of cabling and ccontaining resistance, the utility model is provided with the cannelure 70 that is used to place conductor wire 7 and current-limiting resistance 6 at heart yearn 1 back side, and described conductor wire 7 and current-limiting resistance 6 are placed in the cannelure 70, as shown in Figure 5.

Shown in Fig. 2,3, flexible transparent covering 3 of the present utility model is the plastic layer of flexible and transparent, and this flexible transparent covering 3 is directly to connect injection mo(u)lding on heart yearn 1 by injection machine.The exiting surface of above-mentioned cover layer 3 can be a horizontal plane, also can be the arcuate surface that has radian.For the ease of bending moulding, the preferred main power line of the utility model is copper stranded conductor or metal conductive strips, adopts metal conductive strips can further reduce the thickness of lamp band.Metal conductive strips of the present invention in addition can select for use the metal material with typing ability to make, the lamp band of this moment is because tectal thickness is very little, therefore can make different 2D or 3D moulding according to client's self-demand, and the instrument that does not need other to assist, and can carry out its moulding of manual modification at any time, this relatively DIY function of hommization makes application scenario of the present invention more extensive.

Paster LED of the present utility model can be common direct-current LED (be as a model 3528 paster LED), also can be ACLED, if adopt the direct-current LED rectifier 10 of also will connecting between attaching plug 8 and lamp string 20, so that stable direct current supply to be provided.Exchange driving if adopt ACLED directly to adopt.

Insulating protective layer 11 of the present utility model plays the effect of insulation on the one hand; also can play the effect that installs and fixes on the other hand; as shown in Figure 8; insulating protective layer 11 of the present utility model is one to have the adhered layer of stickup ability; this adhered layer is divided into colloid adhered layer 11a and colloid protective layer 11b; only need in use colloid protective layer 11b is torn, affix directly to thing to be installed surface then and get final product, very convenient.

As Fig. 9, shown in Figure 10, the paster LED that ultrathin flexible lamp band of the present utility model adopted can also be the RGB three-primary color LED, this moment, main power line was divided into first, second, third, fourth power line 51a, 52b, 53c, 54d, the conductor wire of described a plurality of lamp string 20 head ends is electrically connected with first, second, third power line 51a, 52b, 53c respectively, and the conductor wire of described a plurality of lamp string 20 tail ends is electrically connected to the 4th power line 54d respectively.

The above only with convenient explanation the utility model, or else breaks away from the creation spirit category of the present utility model, and any simple modification that those skilled in the art did of knowing this technology still belongs to protection domain of the present utility model with distortion.
