Abstract
Description
Technical Field
[0001] This utility model relates to the field of flexible light strip technology, and in particular to a high-reliability neon light strip. Background Technology
[0002] With the evolution of lighting technology and the upgrading of consumer demand, flexible LED light strips have been widely used in many fields such as indoor decorative lighting, commercial displays, advertising signs, furniture outlines, and automotive lighting due to their outstanding advantages such as bendability, cutability, low power consumption, rich colors, and convenient installation. Their core structure typically includes a flexible circuit board, surface-mount LED beads soldered to the board at certain intervals, conductive lines covering the circuit, and an outermost transparent or semi-transparent encapsulating layer.
[0003] However, this very flexibility also brings with it the inherent challenge of structural fragility. In existing technologies, the LED chips in flexible LED strips are typically directly exposed beneath the outermost encapsulating layer, or covered by only a very thin film, lacking an independent and robust physical protective structure. This design exposes the following serious technical flaws in dynamic bending and complex installation scenarios: 1. Insufficient mechanical protection: Modern LED chips are becoming increasingly larger and more susceptible to physical damage. During the transportation, handling, and especially on-site installation of LED strips, they inevitably encounter squeezing, scratches, or accidental collisions. Directly exposed LED chips, with their limited encapsulation structure (especially the lens), are highly vulnerable to cracks, breakage, or even chip failure due to external impacts. This can lead to the extinguishing of individual or consecutive light spots, severely impacting product yield and initial reliability.
[0004] 2. Weak resistance to bending stress, leading to easy fatigue and detachment of solder joints: Flexible LED strips often require twisting and bending during installation to fit the surface. During this process, the deformation stress generated by the flexible substrate is directly transmitted to the solder joints of the LED chips. Due to the small area of the solder joints and their long-term exposure to stress cycles, they are highly susceptible to metal fatigue, resulting in solder joint cracking or incomplete soldering, causing electrical connection failure, i.e., "LED chip detachment." This is one of the main reasons why flexible LED strips malfunction shortly after installation.
[0005] 3. Limited Environmental Tolerance: Although the outer encapsulating colloid provides some water and dust resistance, the edge sealing and targeted protection of the LED chips in the existing structure are still insufficient for applications requiring higher levels of protection (such as outdoor or humid environments). Moisture and corrosive gases can still penetrate along the interface between the LED chip and the colloid, eroding the solder joints and the chip.
[0006] Currently, to improve protection, the common practice in the industry is to increase the thickness or hardness of the overall potting compound, but this significantly sacrifices the flexibility of the light strip, making it difficult to bend and install, which deviates from the fundamental characteristics of the product; or to use an external rigid sleeve, but this completely loses flexibility and greatly increases the volume and cost. Utility Model Content
[0007] The technical problem to be solved by this utility model is to provide a highly reliable neon light strip that effectively improves the installation firmness of LED beads without affecting the luminous performance of LEDs.
[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a high-reliability neon light strip, comprising a flexible base strip, a light groove formed in the flexible base strip, and a light strip assembly installed in the light groove. The light groove is filled with a light-transmitting adhesive strip for covering and protecting the light strip assembly. The light strip assembly includes a tensile base strip, two conductive strips set in the tensile base strip, and a plurality of LED beads arranged in parallel on the two conductive strips. A transparent protective cover is sealed on the top of each LED bead. A groove is formed on the inner side of the transparent protective cover, and the LED bead is embedded in the groove of the transparent protective cover.
[0009] Preferably, the light strip assembly further includes an insulating sealing strip, and the two conductive strips are located in the interlayer between the tensile base strip and the insulating sealing strip.
[0010] Preferably, the two ends of the transparent protective cover are provided with outwardly protruding connecting bases, which are attached to the upper surface of the insulating sealing strip.
[0011] Preferably, a light-transmitting sealing strip is provided at the opening of the lamp trough, and the edge of the light-transmitting sealing strip is sealed to the openings on both sides of the lamp trough.
[0012] Preferably, the outer side of the light-transmitting adhesive strip is provided with a concave arc surface, and the inner side of the light-transmitting sealing strip is provided with a convex arc surface that is completely fitted with the concave arc surface.
[0013] The beneficial effects of this utility model are as follows: This utility model provides a highly reliable neon light strip. During the assembly process of the light strip, a transparent protective cover is placed on top of each LED bead to prevent the LED beads from loosening or falling off due to the handling, adjustment, or twisting of the light strip during assembly. In practical applications, due to the structural protection of the transparent protective cover, the flexibility of the transparent adhesive strip can be made softer, thereby greatly improving the overall flexibility of the neon light strip, facilitating the layout and installation of the light strip, and making it highly practical.

[0018] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments. The content mentioned in the embodiments is not intended to limit the present invention.
[0019] like Figures 1 to 4 As shown, a high-reliability neon light strip includes a flexible base strip 1, a light groove 2 formed in the flexible base strip 1, and a light strip assembly installed in the light groove 2. The light groove 2 is filled with a light-transmitting adhesive strip 3 for covering and protecting the light strip assembly. The light strip assembly includes a tensile base strip 4, two conductive strips 5 set in the tensile base strip 4, and a plurality of LED beads 6 arranged side by side on the two conductive strips 5. A transparent protective cover 7 is sealed directly above each LED bead 6. A groove 71 is formed on the inner side of the transparent protective cover 7, and the LED bead 6 is embedded in the groove 71 of the transparent protective cover 7. During the assembly of the light strip, each LED bead 6 is covered with a transparent protective cover 7 to prevent the LED bead 6 from becoming loose or falling off due to the handling, adjustment, or twisting of the light strip during assembly. In practical applications, the transparent protective cover 7 provides structural protection, allowing the transparent strip to be more flexible, which greatly improves the overall flexibility of the neon light strip, making it easier to lay out and install, and highly practical.
[0020] In this embodiment, the light strip assembly further includes an insulating sealing strip 8, with the two conductive strips 5 located within the interlayer between the tensile base strip 4 and the insulating sealing strip 8. The insulating sealing strip 8 not only achieves insulation and sealing of the conductive strips 5 but also enables the adhesive bonding and fixing of the transparent protective cover 7, reducing the difficulty of assembling and fixing the transparent protective cover 7 and effectively improving production efficiency.
[0021] In this embodiment, the two ends of the transparent protective cover 7 are provided with outwardly protruding connecting bases 72. The connecting bases 72 are attached to the upper surface of the insulating sealing strip 8 to increase the bonding area between the transparent protective cover 7 and the insulating sealing strip 8, thereby further improving the bonding strength between the two, making the connection more secure and reliable.
[0022] In this embodiment, a light-transmitting sealing strip 9 is provided at the opening of the lamp groove 2. The edge of the light-transmitting sealing strip 9 is sealed and connected to the openings on both sides of the lamp groove 2 to protect the light-transmitting adhesive strip 3 from being eroded or worn off by rainwater, thereby improving the service life of the light-transmitting adhesive strip 3.
[0023] In this embodiment, the outer surface of the light-transmitting adhesive strip 3 is provided with a concave arc surface 31, and the inner surface of the light-transmitting sealing strip 9 is provided with a convex arc surface that completely fits the concave arc surface 31. The design of the concave arc surface 31 and the convex arc surface is used to refract the light generated by the LED beads 6 to the light-transmitting sealing strip 9 located on the light-emitting surface, thereby improving the overall brightness of the neon light strip without increasing the LED luminous power, making it more practical.
