Description

Technical Field

[0001] This utility model relates to the field of decorative lighting technology for door openers, and in particular to a flexible light strip and a door opener. Background Technology

[0002] As users increasingly demand higher aesthetic quality and better user experience, modern gate openers are facing more stringent requirements in terms of appearance design. LED strips, as an important decorative element, not only directly affect the product's visual appeal but also become a key factor in enhancing market competitiveness. For gate openers with complex, irregular structures, using LED strips to match their curved contours provides greater creative freedom for product design.

[0003] However, currently widely used LED strip systems have significant technical limitations: due to insufficient longitudinal and lateral bending performance, existing products struggle to achieve diverse styling adaptations using a single LED strip specification. Non-standardized customization to meet specific styling requirements not only significantly increases development and manufacturing costs but also extends product design cycles and increases process complexity. This technical bottleneck severely restricts innovative development in the exterior design of door openers, objectively creating a technical barrier to product iteration and upgrades. Utility Model Content

[0004] In response to the shortcomings of the existing production technology, the applicant provides a flexible light strip and a door opener, thereby enabling a single specification light strip to adapt to the curved contour features of the door opener, making the appearance and decoration of the light strip of the door opener compatible with both aesthetics and cost-effectiveness, and improving the market competitiveness of the product.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A flexible light strip, comprising:

[0007] A substrate, the substrate being strip-shaped, having a length extending along a first direction and a width perpendicular to the first direction;

[0008] The first notch is located on one edge of the substrate in the width direction, and there are multiple notches that are spaced apart along the first direction;

[0009] The second notch is located on the other side edge of the substrate in the width direction. There are multiple notches, and they correspond one-to-one with the first notches. The substrate between two corresponding first notches and second notches is the deformation area, and the substrate between two adjacent deformation areas is the lamp bead mounting area.

[0010] LED chip components, installed in the LED chip mounting area;

[0011] A circuit board is disposed on the substrate and electrically connects adjacent LED chips.

[0012] Specifically, when multiple adjacent deformation zones undergo longitudinal bending deformation in the same direction under the action of external force, the light strip bends longitudinally; when multiple adjacent deformation zones undergo lateral deformation in the same direction, the light strip bends laterally.

[0013] As a further improvement to the above technical solution:

[0014] The thickness of the substrate is 0.2mm-0.5mm.

[0015] The substrate is a titanium alloy plate or an aluminum substrate with a titanium alloy coating on its outer surface.

[0016] The two corresponding first and second notches are symmetrical about the center line of the substrate width direction.

[0017] The first and second notches are semicircles with openings facing outwards from the substrate.

[0018] Both the first and second notches are right-angled triangles, with one leg of the right triangle flush with the side edge of the substrate. The two corresponding first and second notches are centrally symmetrical about the center point of the deformation zone.

[0019] The ratio of the minimum dimension of the deformation zone along the width direction of the substrate to the width of the substrate is 0.5-0.7.

[0020] The length of the deformation zone along the first direction is equal to the length of the lamp bead mounting zone along the lamp bead mounting zone.

[0021] The back of the substrate is provided with adhesive.

[0022] A door opener equipped with any of the aforementioned flexible light strips.

[0023] The beneficial effects of this utility model are as follows:

[0024] This utility model has a compact and reasonable structure and is easy to operate. By setting a first notch and a second notch on both sides of the substrate of the light strip, a deformation zone is formed along the length of the substrate, which is spaced apart from the lamp beads. Under the action of external force, the deformation zone can undergo lateral and longitudinal deformation, so that the light strip can bend and deform in both directions. This allows a single specification light strip to adapt to the curved contour features of the door opener, making the appearance and decoration of the light strip of the door opener compatible with both aesthetics and economy, and improving the market competitiveness of the product.

[0025] This utility model also has the following advantages:

[0026] (1) The two semi-circular and symmetrical notches reduce the local width of the substrate, making the center of the deformation zone the narrowest and easier to deform. At the same time, the two sides of the deformation zone are arc-shaped to improve the strength of the deformation zone when it is subjected to stress and deformation.

[0027] (2) The two right-angled triangles with central symmetry make the lateral dimensions of the deformation zone the same, ensuring the overall strength of the deformation zone. In addition, when the deformation zone undergoes lateral deformation, the deformation zone is more likely to deform due to the lack of local material in the two triangles in different directions, thus avoiding excessive local extrusion pressure on the deformation zone.

[0034] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0035] Example 1:

[0036] like Figures 1-3 As shown, the flexible light strip of this embodiment includes:

[0037] The substrate 1 is strip-shaped and has a length L extending along a first direction and a width W perpendicular to the first direction.

[0038] The first notch 21 is located on one edge of the substrate 1 in the width direction, and there are multiple notches that are spaced apart along the first direction;

[0039] The second notch 22 is located on the other side edge of the width direction of the substrate 1. There are multiple notches and they correspond one-to-one with the first notch 21. The substrate 1 between two corresponding first notches 21 and second notches 22 is the deformation area 12. The substrate 1 between two adjacent deformation areas 12 is the lamp bead mounting area 11.

[0040] LED component 3 is installed in LED mounting area 11;

[0041] A circuit board is disposed on the substrate 1 and electrically connects adjacent LED beads 3;

[0042] When multiple adjacent deformation zones 12 undergo longitudinal bending deformation in the same direction under the action of external force, the light strip bends longitudinally; when multiple adjacent deformation zones 12 undergo transverse deformation in the same direction, the light strip bends transversely.

[0043] The substrate 1 serves as the supporting structure for the circuit board and is insulated from it. The circuit board and substrate 1 are integrated into one unit. The circuit board is a flexible circuit board with deformation adaptability. It can deform with the substrate 12 under certain deformation conditions while maintaining the integrity of the circuit. The circuit board is provided with cutting marks 5 for easy cutting as needed.

[0044] The LED beads 3 are arranged at equal intervals to ensure that the light emission uniformity meets optical standards. Each LED bead group is equipped with a resistor 4 to achieve overcurrent protection. The LED beads 3 are LED beads.

[0045] By setting a first notch 21 and a second notch 22 on both sides of the substrate 1 of the light strip, a deformation zone 12 is formed along the length direction of the substrate 1, which is spaced apart from the lamp bead 3. Under the action of external force, the deformation zone 12 can undergo lateral deformation and longitudinal deformation, so that the light strip can be bent and deformed in both lateral and longitudinal directions. This allows a single specification light strip to adapt to the curved contour features of the door opener, making the appearance and decoration of the light strip of the door opener compatible with both aesthetics and economics, and improving the market competitiveness of the product.

[0046] The thickness of substrate 1 is 0.2mm-0.5mm, which makes substrate 1 easy to bend and easy to install in narrow slots.

[0047] The substrate 1 is a titanium alloy plate or an aluminum substrate with a titanium alloy coating on its outer surface, which improves the substrate 1's ability to withstand bending.

[0048] The ratio of the minimum dimension of the deformation zone 12 along the width direction of the substrate 1 to the width of the substrate 1 is 0.5-0.7, ensuring the structural strength of the deformation zone 12.

[0049] The length of the deformation zone 12 along the first direction is equal to the length of the lamp bead mounting zone 11 along the lamp bead mounting zone 11, so that the deformation capability of the lamp strip is evenly distributed along the length direction.

[0050] The back of the substrate 1 is provided with adhesive to facilitate the installation of the light strip and fix the shape of the light strip.

[0051] Example 2:

[0052] like Figure 1 , Figure 3 As shown, based on Embodiment 1, the flexible light strip of this embodiment has two corresponding first notches 21 and second notches 22 that are symmetrical about the center line of the width direction of the substrate 1.

[0053] The first notch 21 and the second notch 22 are semicircles with openings facing the outside of the substrate 1.

[0054] like Figure 3 As shown in Figure a, the dashed line indicates that when the deformation zone 12 undergoes lateral deformation, the dashed line area locally arches, causing the relative positions of the two adjacent LED bead installation areas 11 to change, thereby causing the LED strip to bend laterally.

[0055] The two semi-circular and symmetrical notches reduce the local width of the substrate 1, making the center of the deformation zone 12 the narrowest and easier to deform. At the same time, the two sides of the deformation zone 12 are arc-shaped to improve the strength of the deformation zone 12 when it is subjected to force and deformation.

[0056] Example 3:

[0057] like Figure 2 , Figure 3 As shown, based on Embodiment 1, the flexible light strip of this embodiment has a first notch 21 and a second notch 22 that are both right-angled triangles. One right-angled side of the right-angled triangle is flush with the side edge of the substrate 1. The two corresponding first notches 21 and second notches 22 are centrally symmetrical about the center point of the deformation area 12. The deformation area 12 is formed between the hypotenuses of the two corresponding right-angled triangles.

[0058] like Figure 3 As shown in Figures b and c, the dashed lines indicate that when the deformation zone 12 undergoes lateral deformation, the dashed area locally arches, causing the relative positions of the two adjacent LED bead mounting areas 11 to change, thereby causing the LED strip to bend laterally.

[0059] The two right-angled triangles with central symmetry ensure that the lateral dimensions of the deformation zone 12 are the same, thus guaranteeing the overall strength of the deformation zone 12. In addition, when the deformation zone 12 undergoes lateral deformation, the deformation zone 12 is more likely to deform due to the local material loss of the two triangles in different directions, thus avoiding excessive local compressive stress on the deformation zone 12.

[0060] like Figure 3 As shown in Figures b and c, the two bends in different directions are respectively inverted at the two acute vertices of the triangle.

[0061] A transition arc is provided at the acute angle of the right triangle located on both sides of the center line in the width direction of the substrate 1 to prevent stress concentration and tearing when deformation occurs in the deformation zone 12.

[0062] Example 4:

[0063] The door opener of this embodiment includes a lampshade, on which a recessed groove is provided, and a flexible light strip of any of the above embodiments is installed in the recessed groove.

[0064] The door opener can be a roller door opener or a garage door opener.

[0065] like Figure 4 As shown, this is a lampshade for installing a light strip. The light strip is installed on the inner side of the embedding groove indicated by the arrow. The light strip can be installed not only in a loop within the embedding groove, but also with the loop within an arc-shaped curved surface, such as... Figure 5 As shown, the mounting groove has a certain curvature. Workers use plastic tweezers to install the LED strip, which is fixed in the groove using adhesive as it follows the curvature of the groove.

[0066] In addition, for some special shapes, the light strip can also be wavy, which can expand the range of shapes that can be used. The light strip in this embodiment is easy and convenient to install and has a low cost.

[0067] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
