[0002] Existing flexible light strips are generally used for environmental art decoration. Their overall cross-section is flat, and they are powered by flexible circuit boards. Therefore, their LED beads are generally soldered to one or both sides of the flexible circuit board. As a result, the actual light-emitting surface of the flexible light strip is often located on both sides of its thickness direction. For filling decoration in some gaps, the flexible light strip needs to be inserted into them. Using one or both sides of its thickness direction as the light-emitting surface will affect its actual light effect. Utility Model Content

[0003] Based on the above problems, the purpose of this utility model is to provide a flexible decorative light strip with the light-emitting surface located at its height position, which is convenient for embedded and fixed installation.

[0004] To address the above problems, the following technical solution is provided: A flexible decorative light strip, comprising a flexible strip body and a flexible circuit board located within the flexible strip body. The upper side of the flexible circuit board in the height direction has several tabs arranged at intervals along its length direction. The tabs are divided into two groups: one group is bent 90 degrees towards one side of the flexible circuit board in the thickness direction to form a positive tab, and the other group is bent 90 degrees towards the other side of the flexible circuit board in the thickness direction to form a negative tab. The positive and negative tabs are arranged alternately and at intervals along the length direction of the flexible circuit board. The strip also includes LED beads, one of which is located above and soldered to the positive tab, and the other is located above and soldered to the negative tab. The flexible strip body encloses the flexible circuit board and the LED beads, forming a light-emitting strip on the upper side of the flexible strip body in the height direction.

[0005] The present invention is further configured such that the LED beads are in two groups, one group having its positive electrode welded to the positive lug and its negative electrode welded to the negative lug; and the other group having its positive electrode welded to the negative lug and its negative electrode welded to the positive lug.

[0006] The present invention is further configured such that a set of LED beads is welded between each positive ear and one of the negative ears on one side, and another set of LED beads is welded between each positive ear and the negative ear on the other side.

[0007] The present invention is further configured such that the color temperatures of the two sets of LED beads are white light and yellow light, respectively.

[0008] The present invention is further configured such that the light-emitting strip is made of transparent or semi-transparent and / or fluorescent material.

[0009] The present invention is further configured such that the thickness of the lower end of the flexible strip in the height direction gradually decreases to form a wedge-shaped portion.

The upper side of the flexible circuit board 20 in the height direction has a plurality of tabs 21 arranged at intervals along its length direction. The tabs 21 are divided into two groups: one group is bent 90 degrees towards one side of the flexible circuit board 20 in the thickness direction to form a positive tab 211, and the other group is bent 90 degrees towards the other side of the flexible circuit board 20 in the thickness direction to form a negative tab 212. The positive tabs 211 and negative tabs 212 are arranged alternately and at intervals along the length direction of the flexible circuit board 20. It also includes LED beads 30, one electrode of which is located above the positive tab 211 and welded to it, and the other electrode is located above the negative tab 212 and welded to it. The flexible strip body 10 encloses the flexible circuit board 20 and the LED beads 30, forming a light-emitting strip 11 on the upper side of the flexible strip body 10 in the height direction.

[0023] In the above structure, by bending the tab 21 on the upper side of the flexible circuit board 20 to form a platform for supporting and welding the LED beads 30, the LED beads 30, which could originally only be welded to the front or back of the flexible circuit board 20, are moved to the upper side of the flexible circuit board 20. This changes the main illumination direction of the LED beads 30, which could conventionally only emit light from the front or back of the flexible circuit board 20, to the top of the flexible strip 10, thus achieving a reliable illumination direction while filling narrow gaps.

[0024] In this embodiment, the LED beads 30 are in two groups. One group has its positive electrode welded to the positive lug 211 and its negative electrode welded to the negative lug 212; the other group has its positive electrode welded to the negative lug 212 and its negative electrode welded to the positive lug 211.

[0025] In the above structure, different groups of LEDs can be controlled to light up by changing the direction of the current.

[0026] In this embodiment, each positive ear 211 is welded to a set of LED beads 30 between itself and one of the negative ears 212 on one side, and another set of LED beads 30 is welded to the other negative ear 212 on the other side.

[0027] In the above structure, each positive ear 211 and negative ear 212 is welded to two LED beads 30, which effectively increases the LED bead density to improve the light emission uniformity.

[0028] In this embodiment, the two sets of LED beads have color temperatures of white light and yellow light, respectively.

[0029] In the above structure, color temperature can be controlled by adjusting the direction of the current.

[0030] In this embodiment, the light-emitting strip 11 is made of transparent, semi-transparent, or fluorescent material.

[0031] In the above structure, the light-emitting band 11 is preferably made of a semi-transparent material, or a fluorescent agent is added to the semi-transparent material to form a fluorescent effect.

[0032] In this embodiment, the thickness of the lower end of the flexible strip 10 in the height direction gradually decreases to form a wedge-shaped portion 12.

[0033] The above structure facilitates wedging into the gap during installation.

[0034] In this embodiment, the wedge-shaped portion 12 is V-shaped or the two planes are hyperbolic concave.

[0035] In the above structure, when it is laid on the lawn, the wedge 12 is preferably hyperbolic concave in shape, so that it can be embedded in the lawn.

[0036] In this embodiment, the lower side of the flexible belt 10 in the height direction is provided with a plurality of anchoring holes 121 arranged at intervals along its length direction and extending through it in the thickness direction.

[0037] The above structure can improve the adhesion of the installation. For example, when fixing with glue, the glue can enter the anchoring hole 121 to assist in fixing, or in other cases, wire or hooks can be used for auxiliary fixing. When laid on the lawn, it can be used with a J-shaped hook (not shown in the figure). The hook-shaped part of the J-shaped hook (not shown in the figure) is hooked into the anchoring hole 121 and then inserted into the lawn for auxiliary fixing.

[0038] In this embodiment, the flexible circuit board 20 is provided with a set of printed circuits 22 on both the front and back sides, wherein the conductors of one set of printed circuits 22 reach the positive ear 211, and the conductors of the other set of printed circuits 22 reach the negative ear 212.

[0039] In the above structure, double-sided printing can effectively improve the flow capacity and is suitable for long-distance laying.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
