Description

Technical Field

[0001] This utility model relates to the field of wall washer light technology, and in particular to a flexible silicone wall washer light strip with a flat top and three-sided light output. Background Technology

[0002] Flexible silicone wall washer light strips are increasingly widely used in indoor and outdoor decorative lighting, contouring, and wall washing lighting due to their flexibility, ease of installation, and soft light. Traditional flexible wall washer light strips typically employ a single-sided light-emitting structure, where the light source is placed on a single plane of the strip, with the light primarily emanating from one direction. This structure suffers from limitations when uniformly illuminating vertical walls or creating specific lighting effects. Other issues include a limited illumination angle, overly bright spots near the light axis and significant brightness attenuation in more distant areas, and a harsh, less soft overall light effect, making it difficult to achieve a high-quality "wall washer" effect. To improve lighting effects, some light strip designs with multi-angle light emission capabilities have emerged in existing technologies. Achieving three-dimensional light emission typically requires multiple light panels, increasing the number of components, complicating assembly processes, reducing production efficiency, and making it difficult to achieve stable and precise fixation within the flexible silicone shell. Utility Model Content

[0003] To address the aforementioned issues, this technical solution provides a flexible silicone wall washer light strip with flat top and three-sided light output.

[0004] To achieve the above objectives, the technical solution is as follows:

[0005] A flexible silicone wall washer light strip with a flat top and three-sided light output includes:

[0006] The silicone light strip body includes an integrally formed light-transmitting part and a bottom. The cross-section of the light-transmitting part is inverted U-shaped, and it has a front light-emitting surface arranged perpendicularly to each other, as well as a left light-emitting surface and a right light-emitting surface located on both sides of the front light-emitting surface. The light-transmitting part and the bottom form a rectangular mounting cavity.

[0007] The lamp panel includes a top plate segment parallel to the front light-emitting surface, and a left plate segment and a right plate segment that are bent downward from both ends of the top plate segment and are respectively adjacent to the left light-emitting surface and the right light-emitting surface; the left plate segment and the right plate segment are provided with fixing holes;

[0008] The light source includes front LEDs disposed on the top plate section and side LEDs disposed on the left and right plate sections;

[0009] An intermediate component is provided for the top plate segment, the left plate segment, and the right plate segment to cover its top, left, and right sides respectively; the intermediate component is provided with through holes that penetrate both sides of it;

[0010] The fastener includes a rod and clips respectively provided at both ends of the rod. After the fastener passes through the through hole, the clips pass through the fastening hole to restrict the left side plate segment and the right side plate segment to both sides of the middle member.

[0011] As described above, the flexible silicone wall washer light strip with a flat top and three-sided light output has positioning grooves at both ends of the through hole, and a positioning part on one end of the fixing member. After the other end of the fixing member is inserted into the through hole and passes through, the positioning part is embedded in the positioning groove to limit the fixing member.

[0012] As described above, the flexible silicone wall washer light strip with a flat top and three-sided light emission includes a clip head with a conical protrusion limiting part, and the limiting part is provided with a transverse groove that passes through it laterally.

[0013] As described above, the flat-top, three-sided light-emitting flexible silicone wall washer light strip has the left and right plate segments extending out of the bottom of the intermediate component to form a groove. The bottom includes a main body, a protrusion protruding from the top of the main body, and connecting portions protruding from both sides of the main body. The protrusion is used to insert into the groove to adhere to the intermediate component.

[0014] As described above, the flat-top, three-sided light-emitting flexible silicone wall washer light strip also includes a connecting portion protruding from both sides of the main body at the bottom, which is used to adhere to the light-transmitting portion.

[0015] As described above, the flexible silicone wall washer light strip with a flat top and three-sided light output has a fold line between the left side panel, the right side panel, and the top panel, and the fold line is composed of multiple through holes.

[0016] As described above, the flexible silicone wall washer light strip with a flat top and three-sided light output has the front LED beads and the side LED beads arranged in a staggered manner.

[0017] As described above, in the flat-top, three-sided light-emitting flexible silicone wall washer light strip, the width of the through hole gradually decreases from the center to both ends.

[0018] As described above, in the flat-top, three-sided light-emitting flexible silicone wall washer light strip, the length of the through hole is greater than the distance between two through holes.

[0019] The beneficial effects of this application are:

[0020] This invention provides a flexible silicone wall washer light strip with a flat top and three-sided light output. It employs an integrated bent light panel, a middle component, and unique fixing components for mechanical locking, firmly fixing the light panel to the middle component. The middle component is then combined with the bottom, achieving uniform light output from the front, left, and right sides, effectively expanding the illumination range. This structure is not only easy to assemble and reliably connected, effectively resisting stress during bending and installation, preventing light panel displacement or deformation, but also provides additional heat dissipation channels for the light panel through the rational design of the middle component and the bottom, improving product reliability and lifespan.

[0025] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. 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.

[0026] Example 1:

[0027] A flexible silicone wall washer light strip with a flat top and three-sided light output includes:

[0028] The silicone light strip body 1 includes an integrally formed light-transmitting part 11 and a bottom 12. The cross-section of the light-transmitting part 11 is inverted U-shaped, and it has a front light-emitting surface 111 arranged perpendicularly to each other, and a left light-emitting surface 112 and a right light-emitting surface 113 located on both sides of the front light-emitting surface 111. The light-transmitting part 11 and the bottom 12 form a rectangular mounting cavity 13.

[0029] The lamp panel 2 includes a top plate segment 21 parallel to the front light-emitting surface 111, and a left plate segment 22 and a right plate segment 23 that bend downward from both ends of the top plate segment 21 and are respectively adjacent to the left light-emitting surface 112 and the right light-emitting surface 113; the left plate segment 22 and the right plate segment 23 are provided with fixing holes 24.

[0030] The light source 3 includes a front LED 31 disposed on the top plate section 21 and a side LED 32 disposed on the left plate section 22 and the right plate section 23;

[0031] Intermediate component 4 is used for the top plate segment 21, the left plate segment 22 and the right plate segment 23 to cover its top surface, left side surface and right side surface respectively; the intermediate component 4 is provided with through holes 41 that penetrate through both sides of it;

[0032] The fixing member 5 includes a rod 51 and a locking head 52 respectively provided at both ends of the rod 51. After the fixing member 5 passes through the through hole 41, the locking head 52 passes through the fixing hole 24 to restrict the left plate segment 22 and the right plate segment 23 on both sides of the middle member 4.

[0033] This invention provides a flexible silicone wall washer light strip with a flat top and three-sided light output. It employs an integrated bent light panel, a middle component, and unique fixing components for mechanical locking, firmly fixing the light panel to the middle component. The middle component is then combined with the bottom, achieving uniform light output from the front, left, and right sides, effectively expanding the illumination range. This structure is not only easy to assemble and reliably connected, effectively resisting stress during bending and installation, preventing light panel displacement or deformation, but also provides additional heat dissipation channels for the light panel through the rational design of the middle component and the bottom, improving product reliability and lifespan.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, positioning grooves 42 are respectively provided at both ends of the through hole 41, and a positioning part 53 is provided on one end of the fixing member 5. After the other end of the fixing member 5 is inserted into the through hole 41 and passes through, the positioning part 53 is embedded in the positioning groove 42 to limit the fixing member 5. Through the cooperation of the positioning part and the positioning groove, the insertion position of the fixing member is ensured to be consistent, which facilitates the passing of the clamp head through the fixing hole and ensures long-term stability of the locking state. At the same time, the positioning groove provides clearance space. When the limiting distance between the two clamp heads is less than the width of the intermediate member, the clamp head slightly recesses into the positioning groove when locking the left or right plate segment, achieving the locking effect.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the locking head 52 includes a conical protrusion of a limiting portion 521, on which a transverse groove 522 is provided to extend laterally. The conical limiting portion facilitates insertion and passage through the fixing hole, and the transverse groove structure gives the locking head a certain elastic deformation capability, allowing it to return to its original shape after passing through the fixing hole, thereby achieving reliable self-locking or snap-fit ​​and simplifying the assembly operation.

[0036] Furthermore, as a preferred embodiment of this solution and not a limitation, the left side plate segment 22 and the right side plate segment 23 extend beyond the bottom of the intermediate member 4 to form a groove 25. The bottom 12 includes a main body portion 121, a protrusion portion 122 protruding from the top of the main body portion 121, and connecting portions 123 protruding from both sides of the main body portion 121. The protrusion portion 122 is used to insert into the groove 25 to adhere to the intermediate member 4. Through the insertion and engagement of the groove formed by the extension portion of the lamp panel and the bottom protrusion portion, pre-positioning between the lamp panel assembly and the bottom can be achieved before bonding, ensuring accurate alignment of the two, facilitating subsequent bonding operations, increasing the bonding area and bonding strength, and enhancing the stability of the overall structure.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, the bottom 12 also includes connecting portions 123 protruding from both sides of the main body 121, the connecting portions 123 being used to adhere to the light-transmitting portion 11. The connection portions further increase the bonding area and contact line length between the bottom and the light-transmitting portion, not only improving the sealing and firmness of the bond between the two and preventing the silicone shell from coming unglued when bent, but also facilitating the more even conduction of heat generated by the lamp panel to the entire silicone shell for heat dissipation.

[0038] Example 2: The difference from Example 1 is that a fold line 26 is provided between the left side plate segment 22, the right side plate segment 23, and the top plate segment 21. The fold line 26 is composed of multiple through holes 27. The fold line formed by through holes essentially creates a physical weakening line, allowing stress to concentrate at this point and be evenly released when the lamp board is bent. This greatly reduces the risk of copper foil breakage or lamp bead solder joint damage due to bending at the connection between the top and side plate segments, significantly improving the flexibility and bending reliability of the lamp board.

[0039] Furthermore, as a preferred embodiment of this solution and not a limitation, the front LED bead 31 and the side LED bead 32 are staggered. This staggered arrangement of light sources avoids overlapping shadows or overly bright spots projected from different light-emitting surfaces onto the wall surface at close range. This helps to achieve a more uniform and smooth mixing of light on the wall surface, eliminating bright and dark stripes, thereby obtaining a higher quality and more continuous wall-washing effect.

[0040] Furthermore, as a preferred embodiment of this solution and not a limitation, the width of the through hole 27 gradually decreases from the center towards both ends. This gradual change in through hole width ensures the best flexibility and smoothest bending at the center of the fold line, while rigidity gradually increases towards both ends. This design better matches the stress distribution of the light panel during actual bending, further optimizing stress distribution, preventing excessive stress concentration at specific points, and improving bending lifespan.

[0041] Furthermore, as a preferred embodiment of this solution and not a limitation, the length of the through hole 27 is greater than the distance between two through holes 27. The longer through holes and smaller distance mean that the folded area is weakened to a greater extent, forming a more continuous and flexible bending area, thereby providing optimal bending performance while ensuring uninterrupted electrical connection, allowing the lamp panel to adapt to smaller bending radii.

[0042] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
