Technical Field
[0001] This utility model relates to the field of wall washer light technology, and in particular to a high-performance silicone wall washer light strip. Background Technology
[0002] In the fields of architectural landscape lighting and indoor and outdoor decorative lighting, wall washer light strips are widely used due to their ability to produce a continuous and uniform light strip effect. Currently, the market demands higher performance integration and environmental adaptability from wall washer light strips. Products are expected to achieve high brightness output, excellent heat dissipation performance, and top-notch light uniformity, while also possessing excellent multi-dimensional bending capabilities to adapt to complex installation environments, such as curves and corners. Furthermore, a high-reliability IP67 protection rating must be maintained under these conditions. Traditional solutions are mostly rigid structures or only support unidirectional bending, making it difficult to ensure consistency in the light output direction and optical effects in complex curved surface installations; while excessive pursuit of flexibility often sacrifices heat dissipation and optical structure. Therefore, developing a wall washer light strip that simultaneously solves the challenges of multi-dimensional bending, heat dissipation, optics, and protective reliability through innovative mechanical and structural design has become crucial to meeting the needs of high-end customized lighting. Utility Model Content
[0003] To address the aforementioned issues, this technical solution provides a flexible wall washer light that uses an integrated LED chip and lens.
[0004] To achieve the above objectives, the technical solution is as follows:
[0005] A high-performance silicone wall washer light strip, including
[0006] A flexible circuit board includes board body units and connecting units, wherein the two ends of the connecting units are respectively connected to two board body units; the board body units are provided with LED chip pads.
[0007] The connecting unit is bent so that the plate unit can be rolled in the front or back direction; the connecting unit is provided with a hollow groove along its length direction, and the connecting unit is bent to the side so that the plate unit can move to the left or right direction.
[0008] As described above, in a high-performance silicone wall washer light strip, multiple hollowed-out grooves are arranged side by side along the width direction of the connecting unit.
[0009] The high-performance silicone wall washer light strip described above also includes a middle silicone cover plate, which has a downward-facing mounting cavity and a mounting groove on the side wall of the mounting cavity. The plate unit is positioned on the mounting groove to maintain a distance from the top surface of the mounting cavity, and the connecting unit is curved in an arc shape towards the top surface of the mounting cavity.
[0010] The high-performance silicone wall washer light strip described above further includes an outer silicone shell and a flexible module disposed on the middle silicone cover plate, wherein the middle silicone cover plate is disposed inside the outer silicone shell.
[0011] The flexible module includes the flexible circuit board, LED beads disposed on the flexible circuit board, a lens module covering the LED beads, and a heat sink disposed on the back of the flexible circuit board and corresponding to the LED beads.
[0012] As described above, a high-performance silicone wall washer light strip has a first locking hole on the flexible circuit board corresponding to both sides of the lamp bead solder pad, and a second locking hole on the heat sink corresponding to the first locking hole. The lens module includes a plastic bracket with a buckle. The buckle passes through the first locking hole and the second locking hole to fix the lens module and the heat sink to the front and back of the flexible circuit board, respectively.
[0013] As described above, in a high-performance silicone wall washer light strip, the lens module further includes an optical lens, and the plastic bracket is provided with an embedding cavity for the optical lens to be installed, as well as a limiting buckle for restricting the optical lens in the embedding cavity.

[0017] The beneficial effects of this application are:
[0018] This utility model provides a high-performance silicone wall washer light strip. Through the hollow groove, it can achieve bidirectional free bending in both forward and reverse directions and laterally, breaking through the technical barrier that traditional flexible light strips can only be bent in one direction. This allows the light strip to perfectly fit various complex curved surfaces (such as cylinders, arches, and wavy walls), greatly expanding the application scenarios and design possibilities.
[0019] Excellent bending reliability and optical consistency: The hollowed-out grooves act as stress relief zones, effectively dispersing the stress generated on the flexible circuit board during bending and preventing stress concentration that could damage the circuitry or solder joints. Combined with a silicone cover plate, this ensures that the optical lens does not shift during bending, thus guaranteeing consistent and uniform light output under any bending condition.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0024] A high-performance silicone wall washer light strip, including
[0025] The flexible circuit board 1 includes a board body unit 11 and a connecting unit 12, wherein the two ends of the connecting unit 12 are respectively connected to two of the board body units 11; the board body unit 11 is provided with LED chip pads 13;

[0027] This invention provides a high-performance silicone wall washer light strip. Through its perforated grooves, it achieves bidirectional free bending in both forward and reverse directions and laterally, breaking through the technical barrier of traditional flexible light strips that can only bend in one direction. This allows the light strip to perfectly conform to various complex curved surfaces (such as cylinders, arches, and wavy walls), greatly expanding its application scenarios and design possibilities. The perforated grooves, acting as stress relief zones, effectively disperse the stress generated on the flexible circuit board during bending, preventing stress concentration that could damage the circuitry or solder joints.
[0028] Furthermore, as a preferred embodiment of this solution and not a limitation, multiple hollowed-out slots 14 are arranged side-by-side along the width direction of the connecting unit 12. This is beneficial for improving bending performance and connection strength. The hollowed-out slots significantly reduce their lateral bending stiffness, thereby achieving bidirectional bending capability of the light strip in both forward and lateral bends.
[0029] Furthermore, as a preferred embodiment of this solution, and not a limitation thereof, it also includes a middle silicone cover plate 2. The middle silicone cover plate 2 has a downward-facing mounting cavity 21 and a mounting groove 22 on the side wall of the mounting cavity 21. The plate unit 11 is positioned on the mounting groove 22 to maintain a distance from the top surface of the mounting cavity 21. The connecting unit 12 is curved in an arc shape towards the top surface of the mounting cavity 21. The connecting unit provides bending allowance, and the bidirectional bending characteristic makes the installation process more flexible and convenient. The hollowed-out groove forms a flexible support and stress relief mechanism.
[0030] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes an outer silicone shell 3 and a flexible module 4 disposed on the middle silicone cover plate 2, wherein the middle silicone cover plate 2 is disposed inside the outer silicone shell 3; the multi-layer packaging architecture is a progressive packaging system of "hollowed-out flexible circuit board - middle silicone cover plate - outer silicone shell", which achieves IP67 protection while ensuring structural reliability under bidirectional bending.
[0031] Integrated manufacturing process: A step-by-step potting and vulcanization molding process to achieve the above-mentioned hollow FPC composite structure.
[0032] The flexible module 4 includes the flexible circuit board 1, LED beads 41 disposed on the flexible circuit board 1, a lens module 42 covering the LED beads 41, and a heat sink 43 disposed on the back of the flexible circuit board 1 and corresponding to the LED beads 41. The perforated metal heat sink ensures the heat dissipation requirements of the high-power LEDs. The integrated encapsulation of the outer silicone shell provides an IP67 protection rating sufficient to withstand harsh environments, achieving a perfect balance of flexibility, light efficiency, heat dissipation, and protection.
[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, the flexible circuit board 1 is provided with first locking holes 15 corresponding to both sides of the LED pads 13, and the heat sink 43 is provided with second locking holes 431 corresponding to the first locking holes 15. The lens module 42 includes a plastic bracket 421, and the plastic bracket 421 is provided with a buckle 422. The buckle 422 passes through the first locking hole 15 and the second locking hole 431 to fix the lens module 42 and the heat sink 43 to the front and back surfaces of the flexible circuit board 1, respectively. The plastic bracket is precisely fixed to the second locking hole on the heat sink by the buckle. The heat sink is made of a metal with excellent heat dissipation performance, such as aluminum or copper.
[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, the lens module 42 further includes an optical lens 423. The plastic bracket 421 is provided with an embedding cavity 424 for the optical lens 423 to be installed, and a limiting buckle 425 for confining the optical lens 423 in the embedding cavity 424. The 20°x55° dual-angle lens ensures professional-grade wall-washing light efficiency.
[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the middle silicone cover plate 2 is provided with a light-transmitting hole 23 that penetrates the mounting cavity 21 and allows the lens module 42 to pass through, and a limiting ring 24 is provided around the light-transmitting hole 23. In conjunction with the limiting ring on the middle silicone cover plate, the position of the limiting ring is not easily bent, ensuring that the optical lens will not shift during bending, thereby guaranteeing the consistency and uniformity of the light output effect under any bending state.
[0036] Furthermore, as a preferred embodiment of this solution and not a limitation, the middle silicone cover plate 2 has a connecting hole 25 at one end and a connecting buckle 26 at the other end. The connecting buckle 26 is used to fasten with the connecting hole 25 on another middle silicone cover plate 2. This eliminates the need for frequent cutting and splicing, thus handling various complex installation paths and effectively reducing installation time and costs.
[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, the outer silicone shell 3 includes a main body 31 and a transparent portion 32, with a cavity 33 recessed at the bottom of the main body 31. This provides compression space for lateral bending of the outer silicone shell and clearance space for the snap fastener.
