Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and more specifically to a flexible, narrow-angle light-emitting lens light strip. Background Technology

[0002] Chinese patent discloses a decorative LED flexible light strip (application number 2016201892890), comprising a core wire surrounded by a transparent coating layer. The core wire has a receiving channel along its length, within which a flexible circuit board is arranged. A plurality of LED beads are sequentially arranged on the flexible circuit board. The core wire has colored sidewalls with through holes sequentially formed on these sidewalls, and the LED beads are housed within these through holes. The color of the sidewalls of the core wire is the same as or similar to the color of the light emitted by the LED beads. Through this structural design: 1. It achieves consistency between the emitted color of the LED beads and the color of the core wire, and consistency between the LED flexible light strip and the decorative background, thus enhancing the decorative effect; 2. It facilitates the assembly of the LED flexible light strip; 3. It improves the light transmission effect of the LED beads; and it also makes the LED flexible light strip thinner; 4. It provides consumers with a stronger sense of security, thereby increasing the product's appeal; furthermore, it can provide consumers with purchasing guidance. However, the technical solution disclosed in this Chinese patent has the following problems: because it lacks a lens, it is difficult to achieve localized focused lighting, its light diffusion is poor, and its anti-glare is inadequate, making it unsuitable for use in narrow-angle lighting scenarios. In addition, the technical solution disclosed in this Chinese patent can only bend along the length direction (longitudinal) and cannot bend along the width direction (lateral), making it unsuitable for more complex curved surfaces, such as spherical decorations, wave-shaped walls, and streamlined automotive structures. Utility Model Content

[0003] The main purpose of this invention is to solve the above-mentioned problems and provide a flexible, narrow-angle light-emitting lens light strip.

[0004] The technical solution adopted in this utility model is as follows: a flexible narrow-angle light-emitting lens light strip, including a silicone shell, a flexible light-emitting unit, a diffuser plate, and a silicone convex lens. The silicone shell has an upward-facing groove cavity. The bottom of the groove cavity has a recessed groove cavity extending from its top surface to its bottom surface. An inclined wall with an angle of 45° to the top surface of the silicone shell is provided between the bottom wall and the side wall of the groove cavity. The flexible light-emitting unit includes a flexible circuit board fixed on the inclined wall and a number of LED beads equidistantly arranged along the length of the flexible circuit board. The diffuser plate is fixed in the groove cavity and parallel to the inclined wall. The silicone convex lens is disposed at the opening of the groove cavity and has a flat surface and a convex surface. The flat surface is flush with the top surface of the silicone shell, and the convex surface faces the diffuser plate.

[0005] The beneficial effects of this utility model are as follows:

[0006] This invention can concentrate light and reduce scattering, making it suitable for scenarios requiring precise lighting, such as focused lighting for exhibits and window displays. This invention also enables dual-degree-of-freedom bending, allowing bending simultaneously along both the length (longitudinal) and width (lateral) directions, adapting to more complex curved surfaces, such as spherical decorations, wave-shaped walls, and streamlined automotive structures.

[0009] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0010] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0011] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0012] Please refer to Figures 1 to 2 The first embodiment of this utility model is a flexible narrow-angle light-emitting lens light strip, which includes a silicone shell 10, a flexible light-emitting unit 20, a diffuser plate 30, and a silicone convex lens 40.

[0013] In this embodiment, the silicone convex lens is a light-mixing silicone lens. The light-mixing silicone of this lens is a semi-transparent silicone mixture formed by mixing transparent silicone and a diffusing agent in a certain ratio, resulting in more uniform light emission from the LED strip. The diffusing agent can be polyurethane, organosilicon copolymer microspheres, etc., to achieve and enhance the uniform light-mixing effect of the transparent silicone, and also to give the silicone convex lens better light emission characteristics. The silicone convex lens can be referenced to the uniform light-mixing silicone extruded COB LED strip disclosed in Chinese Patent No.: 2020110269823. The silicone convex lens of this invention uses the same material as the silicone lens of the uniform light-mixing silicone extruded COB LED strip (Patent No.: 2020110269823).

[0014] Furthermore, the material used for the silicone housing 10 of this utility model is the same as that used for the silicone housing 10 of the uniformly mixed light silicone extruded COB light strip (patent number: 2020110269823). Those skilled in the art can refer to the uniformly mixed light silicone extruded COB light strip (patent number: 2020110269823) to determine the materials of the silicone housing 10 and the silicone convex lens of this utility model.

[0015] The diffuser plate 30 of this invention is a semi-transparent silicone plate, which is polydimethylsiloxane silicone (PDMS) with the molecular formula (C2H6OSi)n. It has stable chemical properties, high thermal stability and high mechanical strength. The function of the diffuser plate 30 is to diffuse the light spot. In other examples, flexible adhesive materials with similar properties can also achieve the effect of this invention.

[0016] In this embodiment, the silicone housing 10 has a recessed cavity 11 extending from its top to its bottom. The flexible light-emitting unit 20 includes a flexible circuit board 21 fixed to the bottom of the recessed cavity 11 and parallel to the top surface of the silicone housing 10, and a plurality of LED beads 22 equidistantly arranged along the length of the flexible circuit board 21. It is worth noting that the flexible circuit board and LED beads are conventionally used components in the art, and this embodiment does not describe their circuitry or mechanical structure in detail. The diffuser plate 30 is fixed within the recessed cavity 11 above the LED beads 22 and parallel to the top surface of the silicone housing 10. There is a gap between the diffuser plate 30 and the LED beads 22, meaning they do not contact each other, allowing the diffuser plate 30 to diffuse the light emitted by the LED beads 22. The silicone convex lens 40 is disposed at the opening of the recessed cavity 11, and the silicone convex lens 40 has a flat surface 41 and a convex surface 42. The flat surface is flush with the top surface of the silicone housing 10, and the convex surface 42 faces the diffuser plate 30.

[0017] It is worth noting that the two sides of the silicone convex lens are respectively attached to the inner surface of the sidewall of the groove cavity, so that the convex surface of the silicone convex lens and the light-emitting unit form an accommodating cavity A within the groove cavity. That is, the space formed between the convex surface of the silicone convex lens and the surface of the LED bead. The light emitted by the LED bead is refracted outward by the silicone convex lens, and the light is focused by the convex lens, concentrating the light between 10 and 30°. The light concentration mainly depends on the curvature of the silicone convex lens. Different curvatures of silicone convex lenses can achieve different concentrated light illumination areas. The accommodating cavity A also facilitates its bending along its length (longitudinal direction).

[0018] This embodiment can concentrate light and reduce scattering, making it suitable for scenarios requiring precise lighting, such as focused lighting for exhibits and window displays.

[0019] like Figure 2 A second embodiment of this utility model provides a flexible narrow-angle light-emitting lens strip, comprising a silicone housing 10A, a flexible light-emitting unit 20A, a diffuser plate 30A, and a silicone convex lens 40A. The silicone housing 10A has an upward-facing recessed cavity 11A at the bottom of the recessed cavity 11A. The silicone housing 10A has a recessed cavity 11A extending from its top surface to its bottom surface. An inclined wall 12A forming an angle α with the top surface of the silicone housing 10A is provided between the bottom wall and the side wall of the recessed cavity 11A. The flexible light-emitting unit 20A... A includes a flexible circuit board 21A fixed on the inclined wall and a plurality of LED beads 22A equidistantly arranged along the length of the flexible circuit board 21A. The diffuser plate 30A is fixed in the groove cavity 11A and parallel to the inclined wall 12A. The silicone convex lens 40A is disposed at the opening of the groove cavity 11A and has a flat surface 41A and a convex surface 42A. The flat surface 41A is flush with the top surface of the silicone shell 10A and the convex surface 42A faces the diffuser plate 30A.

[0020] The flexible circuit board and the top surface of the silicone shell 10A are combined at a 45° angle. Figure 2 The convex surface of the intermediate lens allows light to be concentrated within a certain area.

[0021] The angle α formed by the inclined wall and the top surface of the silicone shell 10A is 45°.

[0022] There is a gap between the diffuser plate 30A and the LED bead 22A, that is, the diffuser plate 30A and the LED bead 22A do not contact each other.

[0023] It is worth noting that the second embodiment of this utility model differs from the first embodiment only in the tilt angle of the flexible circuit board, that is, the angle between the flexible circuit board and the top surface of the silicone shell; the other structures are the same.

[0024] It is worth mentioning that in this article Figure 2 In the N1 and N2 directions, the direction is along the length direction (longitudinal direction), and the direction is along the width direction (lateral direction).

[0025] In addition to achieving the effects of the first embodiment, this embodiment can also achieve dual-degree-of-freedom bending, which can bend simultaneously along the length direction (longitudinal) and the width direction (lateral), adapting to more complex curved surfaces, such as spherical decorations, wave-shaped walls, and streamlined automotive structures.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
