Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a stable LED flexible light strip. Background Technology

[0002] LED flexible light strips are widely used in commercial lighting, home decoration, stage lighting, and other fields due to their flexible bending performance and efficient light source characteristics. With the rapid development of LED technology, the market demand for flexible light strips is constantly increasing, and the requirements for their performance and lifespan are also gradually improving.

[0003] However, existing LED flexible light strips still face several technical challenges in practical use. First, flexible light strips generate heat during operation. Insufficient heat dissipation leads to heat buildup inside the strip, causing the LED chip temperature to rise and affecting luminous efficiency and lifespan. Second, the heat dissipation structure of traditional flexible light strips is poorly designed, typically using simple silicone protective sleeves or metal substrates as heat dissipation media. However, these materials have limited thermal conductivity, making it difficult to dissipate heat quickly. Furthermore, flexible light strips are prone to damage during bending due to excessive bending, especially in the absence of effective limiting protection. The flexible substrate and LED chips may break due to stress concentration, affecting product durability and reliability. Regarding installation and replacement, traditional LED flexible light strips are usually connected by welding, a complex and time-consuming process that hinders rapid installation and maintenance. The limitations of traditional welding methods are even more pronounced in scenarios requiring frequent replacement or repair, reducing operational efficiency and increasing maintenance costs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stable LED flexible light strip. A flexible graphene film is added between the flexible substrate and the silicone protective layer to improve heat dissipation, and a rubber strip at the lower end prevents excessive bending. It adopts a hot-swappable interface for convenient installation and replacement without welding, ensuring stability and reliability and facilitating future maintenance. It is suitable for commercial, residential, and stage applications.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stable LED flexible light strip, comprising a flexible substrate, an LED bead fixedly connected to the upper end of the flexible substrate, a silicone protective layer fixedly connected to the outer wall of the LED bead, a flexible graphene film fixedly connected to the inner wall of the silicone protective layer, a rubber strip fixedly connected to the lower end of the flexible substrate, a hot-swappable plug fixedly connected to the right end of the flexible substrate, a mating groove formed inside the hot-swappable plug, spring sheets fixedly connected to both the front and rear sides of the hot-swappable plug, a retaining strip fixedly connected to the outer side of the middle of the spring sheet, a pressing plate fixedly connected to the left end of the spring sheet, a hot-swappable connector fixedly connected to the left end of the flexible substrate, a mating joint provided inside the hot-swappable connector, and retaining grooves formed on both the front and rear sides of the inner wall of the hot-swappable connector.

[0006] Furthermore, the lower side of the flexible graphene film is fixedly connected to the upper side of the flexible substrate, and the flexible graphene film abuts against the side of the lamp bead.

[0007] Furthermore, the outer wall of the connector is slidably connected to the inner wall of the mating groove, and the outer wall of the hot-swappable plug is slidably connected to the inner wall of the hot-swappable connector.

[0008] Furthermore, the outer wall of the card strip is engaged with the inner wall of the card slot.

[0009] Furthermore, the upper end of the silicone protective layer is provided with vent holes.

[0010] Furthermore, the flexible graphene film is used to absorb the heat from the LED beads and diffuse it to the outside through the vent holes.

[0011] Furthermore, a conductive copper sheet is provided in the middle of the connector, and an elastic contact is provided inside the mating groove.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this invention, by adding a flexible graphene film between the flexible substrate and the outer silicone protective sleeve, heat dissipation efficiency is significantly improved. The graphene film has high thermal conductivity and excellent flexibility, enabling it to quickly absorb the heat generated during LED operation and diffuse it outward through the vents, effectively reducing the LED strip temperature and extending its service life. Simultaneously, the rubber strips evenly spaced at the lower end of the flexible substrate provide physical restraint when the LED strip is bent at an excessive angle, preventing breakage due to excessive bending, further enhancing the product's durability and reliability.

[0014] 2. This utility model adopts a hot-swappable interface design, enabling rapid installation and replacement without the need for traditional soldering, greatly improving operational efficiency. During installation, the hot-swappable plug and connector precisely align, and the spring clip compresses the retaining strip into the slot, ensuring a stable and reliable connection. For replacement, simply press the pressing plates at both ends; the spring clip will disengage the retaining strip from the slot, easily separating the plug and connector. This design not only simplifies the installation process but also greatly facilitates later maintenance, making it particularly suitable for scenarios requiring frequent replacement or repair, such as commercial lighting, home decoration, and stage lighting.

[0022] 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.

[0023] Reference Figure 1 and Figure 2This utility model provides an embodiment of a stable LED flexible light strip, comprising a flexible substrate 1, characterized in that: an LED bead 2 is fixedly connected to the upper end of the flexible substrate 1, a silicone protective layer 3 is fixedly connected to the outer wall of the LED bead 2, a vent hole 4 is opened at the upper end of the silicone protective layer 3, a flexible graphene film 5 is fixedly connected to the inner wall of the silicone protective layer 3, the lower side of the flexible graphene film 5 is fixedly connected to the upper side of the flexible substrate 1, the flexible graphene film 5 and the side of the LED bead 2 abut against each other, the flexible graphene film 5 is used to absorb the heat of the LED bead 2 and diffuse it to the outside through the vent hole 4, and a rubber strip 6 is fixedly connected to the lower end of the flexible substrate 1.

[0024] Specifically, this LED light strip incorporates a flexible graphene film 5 between the flexible substrate 1 and the outer silicone protective layer 3. The flexible graphene film 5 offers two major advantages: high thermal conductivity and excellent flexibility. During operation, the LED beads 2 generate heat, which the flexible graphene film 5 rapidly absorbs and then dissipates to the external environment through the vents 4, effectively improving the light strip's heat dissipation efficiency and extending the overall lifespan of the device. To prevent the light strip from breaking due to excessive bending, rubber strips 6 are evenly distributed at the lower end of the flexible substrate 1. When the bending angle exceeds a certain range, adjacent rubber strips 6 contact each other, forming a physical limiting mechanism to prevent damage from excessive bending.

[0025] Reference Figures 3-5 A hot-swappable plug 7 is fixedly connected to the right end of the flexible substrate 1. A mating groove 9 is provided inside the hot-swappable plug 7. Spring plates 10 are fixedly connected to both the front and rear sides of the hot-swappable plug 7. A retaining strip 11 is fixedly connected to the outer side of the middle part of the spring plate 10. A pressing plate 12 is fixedly connected to the left end of the spring plate 10. A hot-swappable connector 8 is fixedly connected to the left end of the flexible substrate 1. The outer wall of the hot-swappable plug 7 is slidably connected to the inner wall of the hot-swappable connector 8. A mating joint 13 is provided inside the hot-swappable connector 8. A conductive copper sheet is provided in the middle of the mating joint 13. An elastic contact is provided inside the mating groove 9. The outer wall of the mating joint 13 is slidably connected to the inner wall of the mating groove 9. A retaining groove 14 is provided on both the front and rear sides of the inner wall of the hot-swappable connector 8. The outer wall of the retaining strip 11 is engaged with the inner wall of the retaining groove 14.

[0026] Specifically, in terms of installation and replacement of the LED strip, this flexible LED strip adopts a hot-swappable interface design, which greatly improves efficiency and avoids the tediousness and inconvenience of traditional soldering methods, providing convenience for later maintenance. During installation, simply align the hot-swappable plug 7 accurately with the hot-swappable connector 8 and insert it, allowing the connector 13 to smoothly insert into the mating slot 9. The conductive copper sheet contacts the elastic contact, and at the same time, the spring plate 10 will press the retaining strip 11, causing it to lock into the slot 14, achieving precise positioning and ensuring a stable connection that is not easily loosened. When it is necessary to replace the LED strip, the operation is also very simple. Just press the pressing plates 12 at both ends simultaneously, and the spring plate 10 will move towards the hot-swappable plug 7, thereby causing the retaining strip 11 to disengage from the slot 14. At this time, the hot-swappable plug 7 and the hot-swappable connector 8 can be easily separated.

[0027] Working Principle: This LED flexible light strip improves heat dissipation efficiency by adding a flexible graphene film 5 between the flexible substrate 1 and the outer silicone protective layer 3. The flexible graphene film 5 has high thermal conductivity and good flexibility, which can quickly absorb the heat generated by the LED beads 2 during operation and then diffuse it to the outside through the vent holes 4, thereby improving the heat dissipation efficiency of this LED flexible light strip and extending the service life of the device. Rubber strips 6 are evenly arranged at the lower end of the flexible substrate 1. When the bending angle is too large, the adjacent rubber strips 6 contact to form a physical limit, preventing the LED flexible light strip from breaking due to excessive bending. This LED flexible light strip enables quick installation and replacement via a hot-swappable interface. During installation, the hot-swappable plug 7 is aligned with the hot-swappable connector 8 and inserted, allowing the mating connector 13 to insert into the mating slot 9. The conductive copper sheet contacts the elastic contact point, establishing a connection. The spring plate 10 presses the retaining strip 11 into the retaining groove 14, providing a secure and stable connection. For replacement, simply press the pressing plates 12 at both ends simultaneously. This moves the spring plate 10 closer to the hot-swappable plug 7, causing the retaining strip 11 to disengage from the retaining groove 14, thus separating the hot-swappable plug 7 from the hot-swappable connector 8. This design improves the efficiency of installation and replacement, avoids the inconvenience of traditional soldering methods, and facilitates future maintenance.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
