[0024] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] An embodiment of a folding light strip provided by the present utility model, as Figure 1As shown in the figure, it includes: A board 1 and B board 2 which are arranged side by side with the same width; the A board 1 and B board 2 can be folded along the midline of their connection, and both are provided with at least one set of lamp groups, and each lamp group includes at least one LED chip 4; among them, each set on the A board 1 is provided with a control chip 3; on each lamp group edge of the A board 1 and B board 2, there is a power supply electrode 5 and a ground electrode 6;

[0026] When the A board 1 and B board 2 are folded back to back, the same electrodes of the A board 1 and B board 2 are aligned.

[0027] In this embodiment, by adopting the A board 1 and B board 2 which are arranged side by side and can be folded along the midline, double-sided light emission can be directly achieved through the folding method, solving the problem that traditional light strips need to be cut or pasted back to back to achieve double-sided light emission (360-degree light emission). When the A board 1 and B board 2 are folded back to back, a double-sided light-emitting structure is naturally formed, without the need for complex cutting and pasting operations, greatly simplifying the technological process of achieving double-sided light emission.

[0028] In traditional light strips, the stringing difficulty after back-to-back pasting is relatively high. In this solution, on each lamp group edge of the A board 1 and B board 2, there are a power supply electrode 5 and a ground electrode 6, and when folded, the same electrodes are aligned. This structure makes the connection of the electrodes simpler and more direct after folding, without the need to laboriously perform stringing connections after pasting like the traditional method, reducing the difficulty and complexity of stringing.

[0029] In addition, aiming at the problem of the single function of traditional light strips, this foldable light strip can be applied to more scenarios. For example, when hanging for decoration or lighting, directly using traditional light strips, since they can only emit light on one side, there will be a problem of poor light on one side, and the pasting of traditional light strips needs to be done manually, which is time-consuming, laborious, and inefficient, and inconvenient to use; the foldable double-sided light-emitting light strip of this application can provide a better lighting effect. It can adjust the light-emitting angle by folding to achieve 360-degree light emission, which can provide more comprehensive lighting, increasing the functionality and practicality of the light strip in actual applications.

[0030] In an embodiment of this application, the A board 1 and B board 2 are multi-layer FPCs. The multi-layer FPC (Flexible Printed Circuit) material makes the A board 1 and B board 2 have better flexibility and bendability. Compared with traditional rigid boards, in some scenarios that require bending or conforming to irregular surfaces, the light strip made of multi-layer FPC material can better adapt. For example, the light strip can be bent and installed on a circular lamp housing, or arranged along a curved path, such as wound around railings, tree branches, etc., to achieve more diverse lighting effects.

[0031] Since the light strip is used as a decoration, it can control the brightness and color-changing effects, and can transmit power supply and signals through different layers to optimize the wiring inside the light strip. For example, in an outdoor camping scenario, a foldable light strip made of multi-layer FPC material can be easily wound around the tent support to provide soft lighting inside the tent. Its flexibility enables the light strip to adapt to various shapes and angles of the tent support, and its light weight will not impose too much burden on the tent structure. At the same time, when the tent is being stored, the light strip can also be conveniently folded up without taking up too much space.

[0032] In an embodiment of the present application, test points are provided by opening windows on the back surfaces of the A board 1 and the B board 2. By setting test points by opening windows on the back surfaces of the A board 1 and the B board 2, it provides great convenience for inspection during the production process and later maintenance. In the production link, the electrical performance of the light strip can be quickly detected through the test points, defective products can be discovered and excluded in a timely manner, and the qualified rate of the product can be improved. During use, in addition, since the light strip is symmetrically arranged, after the light strip is folded, the tests of the same functions correspond to each other, so that there will be no short-circuit phenomenon caused by misaligned contact of the test points.

[0033] In an embodiment of the present application, the LED chips 4 on the A board 1 and the B board 2 are arranged at the same spacing and the number of each group is the same. The above-mentioned LED chips 4 on the A board 1 and the B board 2 are arranged at the same spacing and the number of each group is the same, so that the light strip can present a more uniform light distribution when emitting light. Whether it emits light on both sides in the folded state or emits light on one side in the unfolded state, it can avoid the situation of uneven light brightness and improve the lighting quality. This uniform light-emitting effect is very important for some scenarios with high requirements for lighting uniformity, such as photographic lighting and stage lighting, and can provide a more stable and professional lighting effect.

[0034] In addition, the same chip arrangement and quantity design are conducive to realizing the standardization and normalization of mass production. During the production process, it is easier to carry out equipment debugging and process control, improve production efficiency and the consistency of product quality. At the same time, it is also convenient for the procurement and management of raw materials and reduces production costs. For example, when mass-producing foldable light strips, unified production molds and process flows can be adopted to ensure that the light-emitting effects of each product can reach the same standard. Refer to the present application Figure 1 As shown, each group is provided with 12 LED chips 4, which can be set according to requirements. For example, each group can also be set to 6 LED chips 4 or 4 LED chips 4, etc.; correspondingly, it can also be more, and the length of each group can also be increased or shortened accordingly to adapt to different application scenarios.

[0035] In its application, for example, in a photography studio, this evenly emitting folding light strip is used as auxiliary lighting. During the shooting process, the even light can avoid shadows or light spots on the subject, making the shooting effect more natural and clear.

[0036] In one embodiment of the present application, the LED chip 4 is a monochromatic chip or an RGB chip or a WRGB chip.

[0037] The LED chip 4 can be a monochromatic chip, an RGB chip or a WRGB chip, providing users with a rich selection of luminous colors. Monochromatic chips can meet some scenes that require specific colors, such as red warning lights, green indicator lights, etc. RGB chips can achieve a variety of different color luminous effects by adjusting the ratio of red, green and blue, and are suitable for occasions that create various color atmospheres, such as festivals, entertainment venues, etc. WRGB chips add white light to RGB, making the luminous colors richer and more natural, and can be used in scenes that require high brightness and high-quality lighting, such as commercial lighting, interior decoration, etc.

[0038] According to different application scenarios and user needs, different types of LED chips can be selected to make the folding light strip more flexible and adaptable. For example, during family gatherings, the light strip can be set to RGB mode to create a colorful atmosphere; while in reading or working scenes, the white light mode can be selected to provide comfortable lighting. This switchable luminous color function increases the use value and fun of the light strip. In entertainment venues such as bars and KTVs, folding light strips with RGB or WRGB chips are used for decorative lighting. The luminous color of the light strip can be adjusted through the control system according to different music rhythms and scene atmospheres to create a dazzling visual effect and enhance the customer's entertainment experience. In home decoration, this color-changing folding light strip can also be selected to be installed in the living room, bedroom and other places. According to different moods and activity needs, different color modes can be switched to add a unique charm to the home environment.

[0039] In one embodiment of the present application, the two light groups arranged side by side on the A board 1 and the B board 2 are electrically connected to the control chip 3 on the A board 1. The two light groups arranged side by side on the A board 1 and the B board 2 are electrically connected to the control chip 3 on the A board 1, realizing centralized control of multiple light groups. The lighting state of the entire light strip can be uniformly adjusted through one control chip, such as switching, brightness adjustment, color change, etc., which simplifies the design of the control circuit and control system. By arranging the A and B boards in parallel, especially as a fantasy color product, the design of the B board can reduce chips and some electronic materials, reduce the cost of raw materials, and reduce the risk of bending damage.

[0040] In an embodiment of the present application, each set of lamp groups on the A board 1 is further provided with a control electrode 7; the control electrode 7 is located at a position between each set of power supply electrodes 5 and ground electrodes 6 on the A board 1, and forms a control loop with the ground electrode 6. The electrode positions of the above-mentioned A board 1 and B board 2 are in a windowed structure, that is, the electrode positions are exposed on the front and back of the A board 1 and B board 2.

[0041] Each set of lamp groups on the above-mentioned A board 1 is provided with a control electrode 7 and forms a control loop with the ground electrode 6. Only the control electrodes 7 of each set on the A board 1 need to be connected to control the lamp groups arranged side by side on the A board 1 and B board 2. Moreover, the electrodes between the lamp groups serve as a boundary, and a cutting line (not shown in the figure) is also provided at the middle position of the electrodes between each set of lamp groups. When in use, the ones arranged side by side on the A board 1 and B board 2 can be used together as two controllable groups; the A board 1 and B board 2 can also be separated from the connection point. Since each end of each group has a power supply electrode 5 and a ground electrode 6, any one of them can be used as the smallest light-emitting unit, and each set of lamp groups on the A board 1 can be used as the smallest controllable light-emitting unit; when needed, it can be cut from the cutting line, and each group can retain the electrodes and can be independently powered and controlled. This makes it very flexible in application.

[0042] The beneficial effects of the present application also include:

[0043] Traditional processes such as Figure 2 As shown, to achieve 360° light emission, the two FPCBs on the front and back need to be exactly the same (otherwise the same synchronous effect cannot be achieved on the front and back). It is necessary to paste with 3M glue (3M glue can block the window openings of the test points on the front and back of the product to avoid short circuits, and then use the double-sided adhesion characteristics of 3M glue to paste the product, but this increases the overall thickness of the finished product and is prone to light-dark areas); when pasting, the positions on the front and back need to be completely aligned (otherwise the complete synchronization cannot be achieved), and it is necessary to string wires to be used normally (because the front and back boards are completely separated, and in the back-to-back situation, the positive and negative poles of monochromatic products are cross-separated, the positive and negative poles of the RGB SPI products are cross-separated and the signal inputs need to be connected in series, and for DMX512 products, all the lines have cross-strung wires, otherwise they cannot be used normally); it is necessary to ensure the adhesiveness of the adhesion raw material used (otherwise the front and back board materials will separate and detach when the product is bent or heated during lighting, resulting in light spots or dark areas in the lighting).

[0044] Compared with the above traditional light strips, the present application adopts the arrangement mode of side-by-side A and B boards. Firstly, the manufacturing process is simple, which greatly shortens the manufacturing time and reduces the labor cost. When it is used as a colorful product, the design of the B board can reduce the chips and some electronic materials, reducing the raw material cost and the risk of bending damage. Secondly, it does not require auxiliary raw materials such as 3M glue and stringing wires, reducing the raw material cost. It does not require 3M glue or other auxiliary materials for blocking and adhesion, and the back test point openings can be connected together. It does not require stringing, and it can be used normally as long as the solder joints are soldered with tin. Thirdly, the direct folding method ensures the consistency and synchronous effect of the light emission of the product light source. As a colorful product, the front and back are controlled by the same chip, and the effects will be completely synchronous. Fourthly, the form of solder joint connection can reduce the light-emitting dark areas caused by the separation of the plates, preventing the situation of front-back separation and uneven light emission of the product during bending or lighting and heating.
