Description

Technical Field

[0001] This utility model relates to the field of LED rainbow tube technology, specifically to a ring-shaped LED rainbow tube. Background Technology

[0002] LED rainbow tubes are flexible linear decorative lights made with high-brightness LEDs. They are a new type of lighting fixture that replaces miniature bulb neon tubes. They not only have all the advantages of glass neon lights, but also overcome the various shortcomings of neon tubes.

[0003] A search revealed that patent application CN201921830030.X discloses a splicable flexible LED rainbow tube, which includes a rainbow strip body and internal structures such as a main light strip, allowing for splicing according to the required length. While this device achieves splicing functionality through structures such as a fixed mounting shell, a fixed joining shell, and a sealing cap, it lacks a design for sealing and protecting the connection points. External moisture, dust, and debris can easily enter the sleeve, damaging the LED strip and affecting its lifespan. Furthermore, the design for sleeve alignment precision is insufficient, leading to installation difficulties and misalignment due to inaccurate alignment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a ring-shaped LED rainbow tube, which solves the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A ring-shaped LED rainbow tube includes a sleeve, the inside of which is fitted with LED light strips;

[0007] The sleeve has connectors at both ends, and two adjacent sleeves are connected by the connectors. A sealing sleeve is installed at the connector of two adjacent sleeves. The length of the sleeve is adapted to the LED light strip.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, limiting grooves are formed on both sides of the inner wall of the sleeve, and the LED light strip is installed inside the sleeve by limiting grooves.

[0010] The beneficial effects of adopting the above-mentioned further solutions are:

[0011] By creating limiting grooves on both sides of the inner wall of the sleeve, the LED light strip can be stably and securely installed within the sleeve. This not only makes the installation process of the LED light strip simpler and more efficient, but also effectively prevents the light strip from shifting or shaking during use, ensuring the accuracy and stability of the LED light strip's position within the sleeve. This, in turn, ensures the uniformity and consistency of the ring-shaped light emission, improving the overall luminous effect and quality of the LED rainbow tube.

[0012] Furthermore, the sealing sleeve is provided with a second sealing flange, and the connector is provided with a first sealing flange. The sealing sleeve covers the connector of the two sleeves by interlocking with the second sealing flange and the first sealing flange.

[0013] The beneficial effects of adopting the above-mentioned further solutions are:

[0014] The sealing sleeve engages with the first sealing flange on the connector head via a second sealing flange, tightly covering the joint of the two sleeves. This design creates an effective sealing structure, preventing external moisture, dust, and debris from entering the sleeve and thus avoiding damage to the LED strip, extending its lifespan. It also enhances the overall protection and stability of the LED rainbow tube, enabling it to adapt to more complex operating environments.

[0015] Furthermore, both the second sealing flange and the first sealing flange are mountain-shaped.

[0016] The beneficial effects of adopting the above-mentioned further solutions are:

[0017] The second sealing flange and the first sealing flange are designed in a mountain-shaped configuration, which significantly increases the sealing contact area compared to ordinary sealing flanges. When the two flanges interlock, they form a tighter and more reliable seal. The mountain-shaped structure also has a certain degree of elasticity and cushioning, allowing it to better adapt to minor deformations and displacements that may occur at the connector during installation and use. This further improves the reliability of the seal, more effectively preventing the intrusion of moisture, dust, and other contaminants, and ensuring the electrical safety and luminous performance of the LED rainbow tube.

[0018] Furthermore, the end of the connector is provided with a positioning protrusion, and the end of the other connector that is connected to it is provided with a corresponding positioning groove. When two adjacent sleeves are connected through the connector, the positioning protrusion is embedded in the positioning groove to ensure that the two sleeves are accurately connected.

[0019] The beneficial effects of adopting the above-mentioned further solutions are:

[0020] The matching design of the positioning protrusion and positioning groove at the connector end provides precise positioning guidance for the mating of adjacent sleeves. During installation, simply align the positioning protrusion with the positioning groove and insert it to quickly and accurately mate the two sleeves, avoiding installation difficulties and misalignment caused by inaccurate mating. Precise mating results in a more regular and smooth ring structure formed after connecting multiple sleeves, ensuring the overall appearance quality and continuity of the LED rainbow tube's luminous effect, while also improving installation efficiency and reducing installation costs.

[0021] This invention provides a ring-shaped LED rainbow tube. It has the following beneficial effects:

[0022] By opening limiting grooves on both sides of the inner wall of the sleeve, the LED light strip can be quickly and precisely installed inside the sleeve. The installation process is simple and ensures that the LED light strip is stable inside the sleeve, preventing it from shaking or shifting.

[0023] The positioning protrusions and grooves at the end of the connector enable precise alignment between adjacent sleeves during docking, ensuring the overall straightness and accuracy of multiple sleeves after connection, which is beneficial for achieving uniformity and aesthetics in ring-shaped lighting.

[0024] The sealing sleeve installed at the connector interlocks with the first sealing flange through the second sealing flange, covering the connector of the two sleeves. The sealing flange adopts a mountain-shaped design, which can effectively prevent dust, moisture and other substances from entering the sleeve, protect the LED light strip, and improve its service life and stability.

[0025] The sleeve is matched with the length of the LED light strip, avoiding problems such as installation difficulties or material waste caused by the inconsistency in length, while also ensuring the overall aesthetics and compactness of the LED rainbow tube. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1 to 3 As shown, the embodiments provided by this utility model are as follows: Example

[0035] A ring-shaped LED rainbow tube includes a sleeve 1, with an LED strip 4 installed inside the sleeve 1. Limiting grooves 101 are formed on both sides of the inner wall of the sleeve 1, allowing the LED strip 4 to be positioned and installed within the sleeve 1. The limiting grooves 101 on both sides of the inner wall of the sleeve 1 ensure stable installation of the LED strip within the sleeve 1. This not only simplifies and simplifies the installation process of the LED strip but also effectively prevents displacement or shaking of the strip during use, ensuring the accuracy and stability of the LED strip's position within the sleeve 1. This, in turn, ensures the uniformity and consistency of the ring-shaped light emission, improving the overall luminous effect and quality of the LED rainbow tube. Example

[0036] To improve the ease of installation, overall stability, and protection of ring-shaped LED rainbow tubes, while ensuring they exhibit ideal luminous effects, for example, such as Figures 1 to 3As shown, this utility model also includes: connectors 3 at both ends of the sleeve 1, with adjacent sleeves 1 joined together via connectors 3. Each connector 3 has a positioning protrusion at one end and a corresponding positioning groove at the other end. When adjacent sleeves 1 are joined via connectors 3, the positioning protrusion is embedded in the positioning groove, ensuring precise joining of the two sleeves 1. The matching design of the positioning protrusion and positioning groove at the end of the connector 3 provides precise positioning guidance for the joining of adjacent sleeves 1. During installation, simply aligning the positioning protrusion with the positioning groove and embedding it allows for quick and accurate joining of the two sleeves 1, avoiding installation difficulties and misalignment caused by inaccurate joining. Precise alignment makes the ring structure formed by connecting multiple sleeves 1 more regular and smooth, ensuring the overall appearance quality and continuous luminous effect of the LED rainbow tube. It also helps to improve installation efficiency and reduce installation costs. In addition, a sealing sleeve 2 is installed at the joint 3 of two adjacent sleeves 1. The sealing sleeve 2 has a second sealing flange 201, and the joint 3 has a first sealing flange 301. The sealing sleeve 2 covers the joint 3 of the two sleeves 1 by interlocking with the second sealing flange 201 and the first sealing flange 301. The sealing sleeve 2 can tightly cover the joint 3 of the two sleeves 1 by interlocking with the first sealing flange 301 on the joint 3. This design forms an effective sealing structure, preventing external moisture, dust, and debris from entering the sleeve 1, thus avoiding damage to the LED strip and extending its lifespan. It also enhances the overall protective performance and stability of the LED rainbow tube, enabling it to adapt to more complex operating environments. Both the second sealing flange 201 and the first sealing flange 301 are mountain-shaped, significantly increasing the sealing contact area compared to ordinary sealing flanges. When they interlock, they form a tighter and more reliable seal. The mountain-shaped structure also provides elasticity and cushioning, better accommodating minor deformations and displacements at the connector 3 during installation and use, further improving sealing reliability and effectively preventing the intrusion of moisture and dust, ensuring the electrical safety and luminous performance of the LED rainbow tube. The sleeve 1 is matched to the length of the LED strip 4.

[0037] Working principle:

[0038] The LED light strip is embedded in the limiting grooves 101 on both sides of the inner wall of the sleeve 1. The limiting grooves 101 can fix the position of the light strip, ensuring that the light strip is in a predetermined position inside the sleeve 1, avoiding displacement and ensuring the lighting effect.

[0039] By bringing the connectors 3 of adjacent sleeves 1 close together, the positioning protrusion on one connector 3 is embedded into the positioning groove on the other connector 3, achieving precise docking of the two sleeves 1. The design of the positioning protrusion and groove ensures accurate docking of the sleeves 1 and guarantees the precision of the ring installation.

[0040] A sealing sleeve 2 is installed at the joint 3 where the two sleeves 1 meet, and a sealing cap is installed at the end of the two sleeves 1. The second sealing flange 201 of the sealing sleeve 2 and the first sealing flange 301 of the joint 3 interlock with each other. Since both are mountain-shaped, the sealing effect is greatly enhanced, which can prevent water vapor, dust and other impurities from entering.

[0041] After completing the mechanical connection, the LED light strip is electrically connected and the power is turned on, and the LED light strip begins to emit light. Because the sleeve 1 and the light strip are of compatible lengths, the light strip can evenly illuminate the sleeve 1, achieving ring-shaped light emission.
