Description

Technical Field

[0001] The utility model relates to the technical field of LED light strips, in particular to a bent light strip. Background Art

[0002] Most of the existing LED light strips are straight strips. Straight strips have the advantages of easy installation and ultra-long linear lighting. In order to achieve a better bending effect of the straight strips, the existing technology generally punches out notches on both sides of the PCB board (such as Figure 1 However, this gap primarily provides space for the PCB to bend in three dimensions (e.g., straight bend or twist), making it difficult for the PCB to effectively bend laterally in the horizontal plane. Therefore, for corners or unusually shaped building corners or circular lamps, the PCB must be cut and then spliced together to accommodate the unusual angles within a plane. Furthermore, because existing PCBs primarily bend in three dimensions (e.g., straight bend or twist), their structural characteristics limit their ability to achieve extreme bends. Furthermore, significant deformation occurs during bending, causing the lamp's light-emitting angle to shift, impacting the lighting effect. This makes them unsuitable for ultra-thin reflective text and unusually shaped props. Utility Model Content

[0003] The purpose of the present invention is to solve at least one of the technical problems in the prior art and to provide a bending light strip with good side bending effect.

[0004] According to the embodiment of the present invention, the bent light strip includes a plurality of light board units, each of which is provided with a plurality of LED lamp beads. A deformable arc structure is provided between each two adjacent light board units, and the two ends of the arc structure are respectively connected to the adjacent light board units.

[0005] The curved light strip according to the embodiments of the present invention has at least the following beneficial effects: First, because the curved structure has few corners, routing two adjacent light panel units through the curved structure does not create a significant angle, effectively reducing circuit impedance and improving signal integrity. Second, the curved structure is more resistant to bending than other connecting structures. This is because, similar to an arched structure, the curved structure can buffer and distribute the pressure it bears, has excellent bending resistance, and can achieve a larger bending angle than the existing technology. Therefore, when there are multiple light panel units and corresponding arc structures in the light strip, and when the light panel units are smaller and more numerous and the arc structures are more numerous, the overall bending angle and shape of the light strip are more diverse, and the light strip can be bent arbitrarily in the plane. For building corners with corners or special shapes or round lamps, there is no need to cut and then splice the light panel units, and they can be bent directly to adapt to the special angle in the plane; and the bending in the plane will not cause the PCB substrate unit to deform, so that the light-emitting surface and light-emitting angle of the lamp beads are affected, thereby ensuring that the light strip has a good lighting effect and can be applied to ultra-thin text lighting (such as Figure 4 、 Figure 5 As shown) and special-shaped props emit light; and, because the U-shaped structure is deformable, it can also achieve positive bending or distortion in space, which is suitable for lamps with unique shapes (such as Figure 6 shown).

[0006] Additional aspects and advantages of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0015] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0016] In the description of this utility model, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0017] Reference Figure 1 and Figure 6The utility model provides a bendable light strip, comprising a plurality of light panel units 10, each of which is provided with a plurality of LED lamp beads 100, a second wiring pad 12 and a chip resistor 13. The second wiring pad 12 is used for power-on detection. A deformable arc structure 20 is provided between each two adjacent light panel units 10 (preferably, the arc structure 20 and the light panel unit 10 are an integrated structure). The two ends of the arc structure 20 are respectively connected to the side portions 101 of the adjacent light panel units 10, so that the arc structure 20 is higher than the light panel unit 10. First, since the arc structure 20 does not have too many corners, the two adjacent light panel units 10 will not generate too many angled routings when routing through the arc structure 20, which effectively reduces the circuit impedance and improves the signal integrity. Secondly, compared with connection structures of other shapes, the arc structure 20 has a better anti-bending effect, because the arc structure 20 is similar to an arch structure, can buffer and disperse the pressure it bears, and has good anti-bending properties. Furthermore, the arc structure 20 is connected to the side of the light board unit 10 and is higher than the light board unit 10, that is, its bendable portion is higher than the light board unit 10, which is more resistant to bending than directly digging a U-shaped groove on the PCB board. Because when the light strip is bent, a stress is applied to the bending portion, and the bending portion will deform under the action of the stress. However, since the two ends of the bending portion of the arc structure 20 are not directly connected to the ends of the light board unit 10, the arc structure 20 can freely change according to the deformation to eliminate the influence of some stress, so that the adjacent light board units 10 can be bent inward by 0 to 90 degrees (such as Figure 4 As shown), compared with the prior art, it has a larger bending angle. Therefore, when there are multiple light panel units 10 and corresponding arc structures 20 in the light strip, and when the light panel units 10 are smaller and more numerous, and the arc structures 20 are more numerous, the angle and shape of the overall side bending of the light strip are richer, and the light strip can be bent arbitrarily in the plane. For building corners with corners or special shapes or round lamps, there is no need to cut and then splice the light panel units 10, and they can be bent directly to adapt to the special angle in the plane; and the side bending in the plane will not increase the thickness of the entire PCB board, and can be applied to ultra-thin text lighting (such as Figure 4 、 Figure 5 and, since the arc structure 20 is deformable, it can also achieve positive bending or distortion in space, which is suitable for lamps with unique shapes (such as Figure 6 shown).

[0018] In some embodiments, the light panel unit 10 is provided with a cutting position 14 (eg Figure 2The first wiring pad 11 covers part of the shearing position 14, which allows users to cut the light strip as needed while retaining the original design and component layout. The two cut light strips can be welded together through the first wiring pad to ensure that the distance between the two arc-shaped structures on both sides of the welding position remains unchanged, so as to ensure that the bending effect is not limited by the welding position even when the length is ultra-long.

[0019] like Figure 3 As shown, the arc structure 20 includes an inner arc edge 21 and an outer arc edge 22. A chamfer 23 is provided at the connection between the outer arc edge 22 and the side of the lamp panel unit 10. The chamfer 23 serves as a transition and connection. The ends of the inner arc edge 21 are respectively tangent to the edges of the ends 102 of the corresponding lamp panel units 10, so that there are no sharp corners between the connection between the arc structure 20 and the adjacent lamp panel units 10, and the anti-bending effect is good and it is not easy to break.

[0020] Furthermore, the arc angle of the inner arc edge 21 is equal to the arc angle of the outer arc edge 22, so that the arc structure 20 has a consistent overall width, is evenly stressed, is not easily damaged, and has a good anti-bending effect.

[0021] Furthermore, the arc angle is not greater than 90 degrees, so that the height of the arc structure 20 is not too high, saving the material and floor space of the arc structure 20. Preferably, the arc angle is 90 degrees. At this time, the deformation space of the arc structure 20 is larger, and the adjacent two light panel units 10 can be bent inward by 0 to 90 degrees (such as Figure 4 shown).

[0022] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above preferred embodiments can be freely combined and superimposed.

[0023] The above are only preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
