Description

Technical Field

[0001] This utility model relates to the field of light strip technology, and in particular to a perforated FPC light strip. Background Technology

[0002] LED strips, as a commonly used lighting decorative element, are widely used in various scenarios such as home decoration, commercial lighting, and outdoor landscaping. During the installation process, current technology typically uses double-sided adhesive to fix the LED strips.

[0003] However, even with the use of high-strength 3M double-sided tape, its adhesive performance gradually declines over long-term use due to factors such as changes in ambient temperature and humidity, as well as the weight of the LED strip itself. This can lead to the LED strip detaching, affecting its performance and safety. Directly fixing the LED strip with nails or self-tapping screws can easily damage its internal circuitry, causing short circuits, open circuits, and other malfunctions, resulting in strip damage, increased operating costs, and failing to meet users' requirements for installation stability and lifespan. Therefore, this invention proposes a perforated FPC LED strip to at least partially solve the above problems. Utility Model Content

[0004] In view of the above problems, this utility model provides a perforated FPC light strip that overcomes or at least partially solves the above problems.

[0005] To address the aforementioned problems, this utility model discloses a perforated FPC light strip, comprising: The light strip body is composed of N independent light strip units, where N≥1; Each of the aforementioned light strip units is equipped with at least one LED chip; Each independent LED strip unit has an electrode at its end, and the electrodes of adjacent LED strip units are connected as one unit. Each segment of the light strip unit is provided with at least one perforated pin mark, and the circuit structure in the light strip body bypasses the pin mark; A fixing nail is provided, which matches the nail position mark, and the nail length is greater than the thickness of the light strip body.

[0006] Optionally, a dividing line mark is provided between adjacent light strip units; The dividing line mark divides the electrodes between the two sets of light strip units into two parts from the middle.

[0007] Optionally, positive and negative electrode markings are also provided near the electrodes.

[0008] Optionally, the fixing pin is a self-tapping screw.

[0009] Optionally, 3M adhesive is also attached to the bottom of the light strip body.

[0010] Optionally, the front side of the light strip body is provided with transparent waterproof adhesive.

[0011] The embodiments of this utility model have the following advantages: The LED strip body is composed of N independent LED strip units, where N≥1. Each LED strip unit has at least one LED chip. Each independent LED strip unit has an electrode at its end, and the electrodes of adjacent LED strip units are connected as a single unit. Each LED strip unit has at least one perforated pin mark, and the circuit structure in the LED strip body bypasses the pin mark. A fixing pin matches the pin mark, and its length is greater than the thickness of the LED strip body. By setting the pin mark and having the circuit structure bypass the mark, along with a dedicated fixing pin, the LED strip can be firmly fixed, solving the problem of double-sided tape easily falling off after long-term use, and avoiding damage to the circuit during fixing, ensuring the normal operation of the LED strip. The dividing line marking allows the LED strip to be split according to the actual installation length requirements, improving the flexibility of LED strip use. Positive and negative markings facilitate accurate wiring, reduce installation difficulty, and minimize installation errors. The use of self-tapping screws improves fixing reliability and adapts to various installation scenarios. The dual fixing method of 3M adhesive and fixing nails at the bottom further enhances the installation stability; the transparent waterproof adhesive on the front improves the waterproof performance of the light strip and expands its application range.

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] Reference Figure 1In some embodiments of this utility model, a perforated FPC light strip includes: a light strip body 100, which is composed of N independent light strip units, wherein N≥1; each group of light strip units is provided with at least one LED chip 101; each independent light strip unit is provided with an electrode 102 at its end, and the electrodes 102 of adjacent light strip units are connected as one unit; each light strip unit is provided with at least one perforated nail position mark 104, and the circuit structure in the light strip body 100 bypasses the nail position mark 104; a fixing nail 105, which matches the nail position mark 104, and the length of the nail 105 is greater than the thickness of the light strip body 100. This solves the problems of existing light strips being prone to detachment during installation and the use of nails to fix easily damaged circuits; it achieves a firm fixation of the light strip, ensures circuit safety, and ensures the normal operation of the light strip; the light strip is composed of multiple units, and the length can be adjusted according to needs, improving applicability. For example, when installing ceiling light strips in the living room, users can choose this perforated FPC light strip (N=5 segments). It is fixed to the ceiling joists using fixing nails that pass through the nail mark. Because the circuitry bypasses the nail mark, no circuit damage occurs. Compared to traditional double-sided tape-fixed light strips, it shows no signs of detachment even after one year of use. Furthermore, based on the ceiling length, only 3 light strip units are used, leaving 2 segments for other applications.

[0016] Furthermore, a dividing line mark 103 is provided between adjacent light strip units; the dividing line mark 103 divides the electrode 102 between the two sets of light strip units into two parts from the middle.

[0017] Each of the aforementioned LED strip units can be used independently. The LED strip units can be cut from the middle of electrode 102 using scissors or other cutting tools, ensuring that both cut LED strip units retain electrode 102. This allows users to easily split the LED strip according to their installation length requirements. After splitting, each unit retains its complete electrode, without affecting subsequent wiring and use, thus improving the flexibility of the LED strip. For example, when a shop needs a 1.2-meter-long LED strip for window decoration, the purchased perforated FPC LED strip has 4 segments (2 meters in total) of 0.5 meters each. The user can split the strip along the dividing line between adjacent LED strip units, obtaining 3 segments (1.5 meters in total), meeting the window decoration length requirements. Furthermore, the electrodes of the split LED strip units remain intact, and they can emit light after normal power connection.

[0018] Furthermore, positive and negative markings are provided near the electrode 102. These markings prevent reversed polarity during installation, reducing the installation error rate; they also reduce problems such as LED chip damage and LED strip malfunction caused by reversed polarity, thereby lowering operating costs and improving installation efficiency.

[0019] The fixing nail 105 is a self-tapping screw. These self-tapping screws offer strong fixing capabilities and are suitable for various mounting substrates such as wood, plastic, and metal. No pre-drilling is required during installation, simplifying the installation process and improving ease of installation and fixing reliability.

[0020] The bottom of the light strip body 100 is also fitted with 3M adhesive 106, which is a double-sided adhesive. 3M adhesive 106 provides initial fixation of the light strip, facilitating subsequent installation and positioning of fixing screws; this dual-fixation method significantly improves the installation stability of the light strip and further reduces the risk of detachment during long-term use.

[0021] For example, when installing LED strip lights under kitchen cabinets on tiled walls, users can first use the 3M adhesive 106 at the bottom of the strip to initially attach it to the tile, preventing it from shifting during the installation of the fixing nails. Then, the fixing nails can be installed smoothly. After two years of use, even in a humid kitchen environment, the LED strip remains firmly fixed to the wall without any signs of falling off.

[0022] The front of the light strip body 100 is provided with transparent waterproof adhesive. This improves the waterproof performance of the light strip, allowing it to be used in humid environments or outdoors, thus expanding the applicable scenarios for the light strip; the transparent waterproof adhesive does not affect the light-emitting effect of the light strip, ensuring its lighting and decorative functions.

[0023] As an example, refer to Figure 1 , Figure 2 , Figure 3 This utility model provides a perforated FPC light strip, including a light strip body 100 and fixing pins 105. The light strip body 100 is made of flexible printed circuit board (FPC) material, which has good flexibility and can adapt to different installation curved surfaces. The light strip body 100 is composed of 3 independent light strip units (N=3, N can be adjusted according to actual production needs, such as 1 unit, 2 units, 4 units, etc.). Each light strip unit has 2 LED chips 101 soldered on it. The LED chips 101 are surface-mount packaged and soldered to the preset pads of the light strip unit to realize the lighting function.

[0024] Each LED strip unit has a copper electrode 102 at its end. The electrodes 102 of adjacent LED strip units are connected together by welding to form a conductive path, ensuring that the circuit between each LED strip unit is connected. After power is applied, all LED chips 101 can light up normally.

[0025] Each light strip unit has a perforated nail mark 104 on each side edge. The nail mark 104 is a circular through hole structure. When designing the circuit layout of the light strip body 100, the copper foil line is bypassed by the circular through hole to avoid the line passing through the nail mark 104 area and to prevent the circuit from being damaged when the subsequent fixing nail 105 passes through.

[0026] The fixing nail 105 is a self-tapping screw with a diameter that matches the hole diameter of the nail position mark 104 and a length that is 5mm longer than the thickness of the light strip body 100. This ensures that the fixing nail 105 can penetrate the light strip body 100 and reach the substrate (such as wood or plastic) for secure fixing.

[0027] Between adjacent LED strip units, there is a black dividing line mark 103. This dividing line mark 103 is straight and precisely divides the electrode 102 connecting the adjacent LED strip units into two parts in the middle. When it is necessary to shorten the length of the LED strip, the LED strip unit can be split along the dividing line mark 103. After splitting, the end of each LED strip unit still retains an intact electrode 102, which does not affect subsequent use.

[0028] Next to electrode 102, red "+" and blue "-" signs are printed as positive and negative markings, respectively. During installation, the operator can connect the LED strip electrode 102 to the corresponding positive and negative terminals of the power supply according to these markings to avoid reverse connection, which may damage the LED chip 101 or prevent it from emitting light.

[0029] At the bottom of the light strip body 100, a layer of 3M adhesive 106 is bonded by pressure-sensitive adhesive. The area of ​​3M adhesive 106 is the same as the bottom area of ​​the light strip body 100. When using it, first peel off the release paper of 3M adhesive 106, then initially stick the light strip body 100 to the installation position, and then screw the fixing nail 105 through the nail position mark 104 into the mounting substrate to complete the double fixing.

[0030] On the front of the light strip body 100, a layer of transparent epoxy resin waterproof adhesive is coated. The waterproof adhesive covers the entire front of the light strip body 100, including the LED chip 101 and electrode 102 area (the electrode 102 connection end has a reserved wiring notch). The waterproof adhesive has a waterproof rating of IP65, which can effectively prevent moisture from entering the interior of the light strip. It is suitable for humid environments such as kitchens, bathrooms or outdoor corridors.
