Example one

In the present embodiment, as shown in fig. 1, fig. 2 and fig. 3, a light strip is provided, which includes a light strip sleeve 10, two connectors 20, a connecting wire 21 and a light strip 12. Specifically, the two connectors 20 are respectively located at two ends of the lamp strip sleeve 10, the connecting wire 21 is inserted into the connectors 20, and the lamp strip 12 penetrates through the lamp strip sleeve 10. In a specific product structure, the light bar 12 is electrically connected with the connector 20, and the connecting wire 21 for connecting a power supply transmits electric quantity to the light bar 12 through the connector 20; wherein, female PIN structure has on the connector 20, public PIN structure has on the connecting wire 21, and the grafting of public PIN and female PIN makes connecting wire 21 with the convenient connection of connector 20.

Further, the lamp strip sleeve 10 comprises a tube body 11, and a through groove 1111 for facilitating the lamp strip 12 to pass through is formed inside the tube body 11 along the length direction of the tube body. Specifically, the through groove 1111 and the light bar 12 are disposed in a shape-copying manner and in clearance fit, so that the light bar 12 can be conveniently inserted into the light strip sleeve 10 through the through groove 1111. In the specific use process, the lamp strip sleeve 10 and the lamp strip 12 with proper lengths are cut according to the specific installation environment, the lamp strip 12 penetrates through the through groove 1111 to be arranged on the lamp strip sleeve 10, then the two connectors 20 are respectively packaged at the rear end of the lamp strip sleeve 10, the connecting wire 21 is inserted into the connectors 20, and finally the lamp strip is started to be used for lighting decoration after the connecting wire 21 is connected with a power supply.

Further, the tube body 11 includes a light guide layer 111, a refraction layer 112 and a light shielding layer 113, the penetrating groove 1111 is formed in the light guide layer 111, and the light bar 12 penetrates through the light guide layer 111 through the penetrating groove 1111. Specifically, the refractive layer 112 and the light shielding layer 113 are sequentially stacked from inside to outside and wrap a part of the outer wall surface of the light guide layer 111, so that the outer wall surface of the light guide layer 111, which is not wrapped, forms a light emitting surface 1112, and the outer wall surface of the light shielding layer 113 forms a light shielding surface 1131.

Example two

As shown in fig. 4 and 5, the present embodiment is different from the first embodiment in that: the lamp area still includes the magnetic sheet 13 that equidistant setting, specifically, magnetic sheet 13 equidistant embedded in lamp area sleeve pipe 10.

As shown in fig. 6 and 7, the accommodating grooves 114 with the same number as the magnetic sheets 13 are dug from the outer wall surface of the light shielding layer 113, the magnetic sheets 13 are accommodated in the corresponding accommodating grooves 114, and the end surfaces of the magnetic sheets 13 for fixing the lamp strip are flush with the outer wall surface of the light shielding layer 113, wherein the lamp strip is fixed by attracting the end surfaces of the magnetic sheets 13 to the external mounting surface. Compared with the existing fantasy-color neon lamp strip which is fixed by adopting a back glue or a buckle, the neon lamp strip has the advantage of firm installation; the back adhesive fixing mode causes the lamp strip to be installed infirm because the adsorption force of the back adhesive cannot be maintained for a long time; the snap-fit fastening requires additional structural members, which increases the cost. Meanwhile, two mounting modes of gum or buckle have certain thickness due to being fixed on the surface of the lamp strip, so that a certain distance is generated between the lamp strip and an external mounting surface, the lamp strip cannot be completely attached to the mounting surface, and the using effect of a product is affected. This application lamp area magnetic sheet 13 adopts embedded in the mode in the lamp area sleeve pipe 10 both can make lamp area and external installation face laminate completely to guaranteed the lamp area installation stability greatly because of magnetic attraction, be difficult for droing, solved current lamp area installation jail and with lamp area surface external installation face influence pleasing to the eye scheduling problem of not laminating.

Further, the light strip further includes a carrying plate 14 for carrying the magnetic sheet 13, and the receiving groove 114 intersects with the carrying plate 14, so that the magnetic sheet 13 abuts against the carrying plate 14.
