[0024] The technical problem of the present application is effectively solved by providing a narrow edge LED lamp strip, which effectively solves the problem of uneven glue coating on the bottom of the lamp strip due to the narrow frame of the narrow edge LED lamp strip, limited operation space, and difficult uniform glue coating on the bottom of the lamp strip, which affects the re-pasting effect of the lamp strip. Embodiment

[0025] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 indicated, the technical scheme in the present application effectively solves the technical problem of uneven glue coating on the bottom of the lamp strip due to the narrow frame of the narrow edge LED lamp strip, limited operation space, and difficult uniform glue coating on the bottom of the lamp strip, which affects the re-pasting effect of the lamp strip, and the overall idea is as follows:

[0026] The utility model provides a narrow edge led lamp strip, including substrate 1, the upper surface fixedly connected with the light emitting chip 2 of substrate 1, the outside fixedly connected with the connecting wire 3 of substrate 1, the one side sleeve of substrate 1 close to connecting wire 3 is connected with the protection interface 4, the lower surface of substrate 1 places the paste strip 5 for fixing substrate 1, the lower surface of paste strip 5 is attached with the release paper 6 for isolating paste strip 5 with outside environment.

[0027] The upper surface of paste strip 5 is fixedly installed six silica gel strips 7, the upper surface of each silica gel strip 7 is fixedly installed with fixed foot 9, fixed foot 9 has elasticity, the one side of substrate 1 corresponding each silica gel strip 7 is all set up fixed hole 8, and silica gel strip 7 is clamped in the inside of fixed hole 8.

[0028] The one side of substrate 1 corresponding each fixed foot 9 is all fixedly installed with protection block 10, and protection block 10 is rubber material, and the outside of protection block 10 is set up fixed slot 11 for installing fixed foot 9.

[0029] The inside of each fixed slot 11 is set up built-in slot 13, and the inside of each built-in slot 13 is fixedly connected with the spring piece 12 for limiting fixed foot 9.

[0030] The one end of paste strip 5 away from connecting wire 3 is set up two mounting slots 15, and the inside of each mounting slot 15 is fixedly connected with the sealing paper 14 for fixing release paper 6, and the sealing paper 14 away from mounting slot 15 end is fixedly connected in the outside of release paper 6.

[0031] Paste strip 5: its main function is to fix the lamp strip in the preset installation position, through the adhesion of itself, can firmly stick on the surface of various objects, realizes the convenient installation of lamp strip;

[0032] Release paper 6: closely stick in the lower surface of paste strip 5, act as the protection screen of paste strip 5 adhesion, before the installation of lamp strip, it can effectively prevent the adhesion of paste strip 5 and other objects, ensure that when needing to install lamp strip, paste strip 5 still can keep good paste performance;

[0033] Silica gel strip 7: six silica gel strips 7 are evenly distributed on the upper surface of paste strip 5, they have good elasticity and flexibility, by clamping in the fixed hole 8 of the corresponding position of substrate 1, realize the connection of paste strip 5 and substrate 1;

[0034] Fixed foot 9: fixedly installed on the upper surface of each silica gel strip 7, and has elasticity, its main role is to further strengthen the connection strength of paste strip 5 and substrate 1 on the basis of silica gel strip 7 and fixed hole 8 clamping, realizes the stable connection by cooperating with the fixed slot 11 on protection block 10;

[0035] The elastic sheet 12 is fixedly connected inside each built-in slot 13, and is a key component for fixing the fixing leg 9. When the fixing leg 9 is pressed into the fixing slot 11, the fixing leg 9 pushes the elastic sheet 12 into the built-in slot 13. When the fixing leg 9 is in place with the inner wall of the fixing slot 11, the elastic sheet 12 is reset under the action of its elasticity, thereby limiting the fixing leg 9 from accidentally coming out of the fixing slot 11, thereby ensuring the reliability of the connection between the adhesive strip 5 and the base plate 1.

[0036] The sealing paper 14 is fixed at one end outside the release paper 6 and at the other end inside the mounting slot 15. The main function of the sealing paper 14 is to fix the release paper 6, so as to prevent the release paper 6 from moving or separating from the adhesive strip 5 due to external force or its own gravity when the lamp strip is not in use.

[0037] Working principle:

[0038] In the first step, when the adhesion of the adhesive strip 5 fails, the connection between the silica gel strip 7 on the adhesive strip 5 and the fixing hole 8 is released by pulling the adhesive strip 5, so that the connection between the adhesive strip 5 and the base plate 1 is released. Then, a new adhesive strip 5 is attached to the lower surface of the base plate 1. In this process, the silica gel strip 7 enters the inside of the fixing hole 8. At this time, the installation of the adhesive strip 5 is completed. Then, the connection between the release paper 6 and the adhesive strip 5 is released, and the base plate 1 is installed at the predetermined position through the adhesive strip 5.

[0039] In the second step, after the adhesive strip 5 is connected to the base plate 1, the fixing leg 9 is pressed into the inside of the fixing slot 11. In this process, the fixing leg 9 with elasticity is deformed to a certain extent, and at the same time, the elastic sheet 12 is gradually pushed into the inside of the built-in slot 13. As the fixing leg 9 continuously penetrates into the fixing slot 11, when the surface of the fixing leg 9 is completely attached to the inner wall of the fixing slot 11, the pushing force of the fixing leg 9 on the elastic sheet 12 disappears. After losing the limitation of the fixing leg 9, the elastic sheet 12 quickly moves and resets under the action of the elastic force.

[0040] Finally, it should be noted that the above embodiments are only examples for clearly illustrating the present application, and are not limitations on the embodiments. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to enumerate all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
