Description

Technical Field

[0001] This utility model relates to the field of LED lighting equipment technology, and more specifically, to a smart silicone neon light strip that is resistant to tensile and torsion and has emergency lighting capabilities. Background Technology

[0002] Silicone neon light strips are widely used in commercial lighting, home decoration, and outdoor landscape lighting due to their flexibility, rich colors, and uniform light output. However, existing silicone neon light strips still have many shortcomings in practical applications. First, in terms of physical properties, traditional silicone neon light strips typically use continuous flexible printed circuit boards (FPCs) or ordinary wires as conductive paths. When subjected to tensile or torsional forces, the internal conductive lines are prone to breakage or poor contact due to stress concentration, leading to light strip failure. Therefore, their tensile and torsional resistance is weak, making it difficult to meet the requirements for complex installation or long-term reliable operation in environments susceptible to external forces. Second, existing products rarely integrate emergency lighting functions, failing to provide necessary illumination in emergencies such as unexpected power outages, posing a safety hazard. Utility Model Content

[0003] The present invention provides an intelligent silicone neon light strip that is resistant to tensile and torsion and has emergency lighting capabilities, which can solve the above-mentioned problems.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0005] This utility model provides a smart silicone neon light strip that is resistant to tensile and torsion and has emergency lighting capabilities, comprising:

[0006] Composite silicone sleeve;

[0007] A segmented FPC module group is disposed within the composite silicone sheath, comprising multiple mutually separated FPC modules and flexible conductive connectors for connecting adjacent FPC modules.

[0008] Spiral reinforcing filaments are implanted within the composite silicone sheath and distributed along the length of the light strip; and

[0009] The intelligent control module is electrically connected to the segmented FPC module group, and the intelligent control module includes an energy storage element for supplying power when the main power supply is interrupted.

[0010] Preferably, the composite silicone sheath comprises a sleeve body formed by co-extruding a top silicone light-emitting strip, a bottom silicone light-emitting strip, a left side silicone light-emitting strip, and a right side silicone light-emitting strip, and an inner layer of light-transmitting silicone strip placed inside the sleeve body; the top, left, and right sides of the inner layer of light-transmitting silicone strip are respectively pressed and adhered to the top silicone light-emitting strip, the left side silicone light-emitting strip, and the right side silicone light-emitting strip.

[0011] There are two spiral reinforcing filaments, which are respectively implanted into the left side silicone light-emitting strip and the right side silicone light-emitting strip;

[0012] The bottom silicone light-emitting strip, the inner translucent silicone strip, the left side silicone light-emitting strip, and the right side silicone light-emitting strip enclose the space that covers the intelligent control module and the segmented FPC module group.

[0013] Preferably, the left and right silicone light-emitting strips are L-shaped structures symmetrically distributed on the left and right sides of the bottom silicone light-emitting strip, and they are pressed and adhered to the left and right sides of the bottom silicone light-emitting strip in the horizontal part at the bottom; the top silicone light-emitting strip is uniformly distributed with optical diffusion microbeads.

[0014] Preferably, the spiral reinforcing wire is a nickel-titanium alloy wire.

[0015] Preferably, the flexible conductive connector is a cured organic conductive silicone.

[0016] Preferably, the light strip further includes an optical diffusion layer disposed on the side of the inner light-transmitting silicone strip facing the segmented FPC module assembly.

[0017] Preferably, the optical diffusion layer is a titanium dioxide coating.

[0018] Preferably, the intelligent control module further includes: a microcontroller; a constant current drive chip; and a light sensor.

[0019] Preferably, each of the FPC modules is provided with an emergency lighting sub-circuit, which is electrically connected to the energy storage element of the intelligent control module.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1) By embedding spiral reinforcing wires in the silicone sheath, the light strip is endowed with excellent tensile and torsional resistance; at the same time, the structure of segmented FPC module groups interconnected by flexible conductive connectors disperses stress to multiple flexible connection points, avoiding damage to the internal conductive lines when bending or torsion; the synergistic effect of the two makes this light strip adaptable to complex installation environments and effectively extends its service life.

[0022] 2) It integrates an intelligent control module containing energy storage components. When the main power supply is normal, the energy storage components are in charging or standby mode. Once the main power supply is interrupted, the intelligent control module immediately controls the energy storage components to supply power to the light strip, achieving a seamless switch to emergency lighting mode. This design greatly improves the safety and practicality of the product in emergency situations.

[0023] 3) The segmented FPC module design, combined with flexible conductive connections, ensures the stability of electrical connections under various deformation conditions. At the same time, the integrated intelligent control module provides a powerful "brain" for the light strip, which not only realizes the core emergency lighting function, but also provides a platform for integrating various intelligent functions such as ambient light sensing, constant current drive, and remote control, meeting the diverse needs of modern lighting scenarios.

[0024] 4) By forming a double-layer diffusion structure through the PMMA diffusion microbeads in the top silicone light strip and the TiO2 optical diffusion layer on the inner silicone strip, the light is fully scattered, effectively eliminating the bright spots of the LED beads, and achieving a light-free, uniform and soft linear light output effect, resulting in a better visual experience.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0034] Please see Figures 1 to 5 This utility model provides an intelligent silicone neon light strip with tensile and torsion resistance and emergency lighting, which includes: a composite silicone sheath, a segmented FPC module group 6 disposed in the sheath, a spiral reinforcing filament 7 embedded in the sheath, and an intelligent control module 8 electrically connected to the segmented FPC module group 6.

[0035] Structural description of the composite silicone sheath:

[0036] like Figure 2 As shown, the composite silicone sheath is integrally molded using a co-extrusion process. Its structure includes: an inner translucent silicone strip 1, and a top silicone light-emitting strip 2, a bottom silicone light-emitting strip 3, a left side silicone light-emitting strip 4, and a right side silicone light-emitting strip 5 covering the outer layer.

[0037] The inner translucent silicone strip 1 is made of fumed silicone with high light transmittance (≥90%) and high anti-aging properties. It is used to protect the internal segmented FPC module group 6 and intelligent control module 8, and to initially disperse the light. Its top, left and right parts are respectively pressed and bonded to the top silicone light-emitting strip 2, the left silicone light-emitting strip 4 and the right silicone light-emitting strip 5.

[0038] The top silicone light strip 2 is a diffusion-type fumed silica gel, in which 10% (volume percentage) of PMMA (polymethyl methacrylate) optical diffusion microspheres are uniformly mixed. This structure can efficiently and uniformly scatter the light emitted from the segmented FPC module group 6, eliminate bright spots of the LED beads, and achieve a uniform light output effect without dark areas.

[0039] The left-side silicone light strip 4 and the right-side silicone light strip 5 are made of milky white fumed silica, possessing IP67-level waterproof and dustproof capabilities, and strong weather resistance (no yellowing after 500 hours of QUV testing). They are L-shaped and symmetrically distributed on the left and right sides of the bottom silicone light strip 3. Their bottom horizontal sections are pressed and adhered to the bottom silicone light strip 3, providing structural support and lateral protection for the light strip.

[0040] The bottom silicone light strip 3, the inner translucent silicone strip 1, the left side silicone light strip 4, and the right side silicone light strip 5 together form an internal space for accommodating and covering the segmented FPC module group 6 and the intelligent control module 8.

[0041] Structural description of helical reinforcing filament 7:

[0042] In this embodiment, two spiral reinforcing wires 7 are embedded inside the left-side silicone light-emitting strip 4 and the right-side silicone light-emitting strip 5, respectively. These reinforcing wires are made of 0.2mm diameter nickel-titanium alloy wire, which exhibits superelasticity after annealing at 300℃. The reinforcing wires are spirally formed with a 10mm pitch and distributed parallel to the length of the light strip. This structure endows the light strip with excellent tensile strength (≥150MPa) and torsional resistance (able to withstand ±270° cyclic torsion 100 times without damage), effectively protecting the internal circuitry from damage when subjected to external forces.

[0043] Structural description of segmented FPC module group 6:

[0044] like Figure 3 and Figure 4 As shown, the segmented FPC module group 6 consists of multiple mutually separated FPC modules 61 and flexible conductive connectors 62 for connecting adjacent FPC modules 61.

[0045] Each FPC module 61 is made of a 0.1mm thick polyimide (PI) substrate, measuring 10mm × 12mm. An 18μm thick copper foil is applied to the surface to form conductive lines. SMD LEDs are arranged on one side of the module, with a spacing of 10–15mm between the LEDs.

[0046] Adjacent FPC modules 61 are electrically and mechanically connected via flexible conductive connectors 62. These flexible conductive connectors 62 are cured organic conductive silicone with a silver content of 80% and a thickness of 0.1 mm. By coating the conductive silicone onto pre-reserved pads at the edges of adjacent FPC modules 61 and then hot-press-welding them at 180°C and 0.5 MPa, a flexible connection capable of withstanding ±180° bending is formed, with a conduction resistance of less than 50 mΩ. This segmented connection method distributes stress across multiple connection points, avoiding the stress concentration problem at bending points in traditional continuous FPC boards.

[0047] Structure of optical diffusion layer 9:

[0048] like Figure 2 As shown, an optical diffusion layer 9 is disposed on the inner surface of the inner transparent silicone strip 1, facing the segmented FPC module group 6. This diffusion layer is a 0.05 mm thick titanium dioxide (TiO2) coating composed of titanium dioxide nanoparticles with a particle size of 20–50 nm. This coating works synergistically with the PMMA microspheres in the top silicone light-emitting strip 2 to further enhance the light scattering effect, improving the final luminous flux uniformity to over 95%.

[0049] Structure of Intelligent Control Module 8 and Emergency Lighting Circuit:

[0050] like Figure 1 and Figure 5 As shown, the intelligent control module 8 is installed at the end of the light strip or one per meter as needed. The module measures 40mm × 12mm and is 0.15mm thick. It integrates:

[0051] Microcontroller 81: such as the ESP32 chip, with built-in Bluetooth 5.0 and WiFi capabilities, used to process various intelligent control commands.

[0052] Constant current driver chip 82: such as LM3409, is used to provide a stable driving current for LED beads to ensure consistent brightness.

[0053] Light sensor 83: such as BH1750, is used to sense ambient light intensity and realize automatic brightness adjustment.

[0054] Energy storage element 84: For example, a 5.5V, 0.1F button-type supercapacitor, used to provide power when the main power supply is interrupted.

[0055] To enable emergency lighting, each FPC module 61 is equipped with an emergency lighting sub-circuit. This sub-circuit shares LED beads with the main lighting circuit and includes current-limiting resistors and charge / discharge resistors. During normal operation, the intelligent control module 8 controls the main power supply to charge the energy storage element 84. When the intelligent control module 8 detects a main power interruption, it immediately controls the energy storage element 84 to discharge, illuminating the LED beads through the emergency lighting sub-circuit, thus achieving seamless emergency lighting functionality.

[0056] In the LED strip molding process, the FPC modules 61 are first connected together using flexible conductive connectors 62 (organic conductive silicone). SMD LEDs are then soldered onto the FPC modules 61, with the LED spacing controlled at 10-15mm and the emitting surface facing the diffuser silicone. Adjacent FPC modules 61 are connected via pads on their connectors, coated with organic conductive silicone, and then hot-pressed at 180℃ and 0.5MPa to achieve flexible conductive connections between modules. At the front end of the LED strip, an intelligent control module 8 is soldered and installed, and the circuitry of the intelligent control module 8 is precisely connected to the pads of the FPC modules 61.

[0057] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
