Description

Technical Field

[0001] This utility model relates to the field of LED display technology, and in particular to an integrated outdoor LED flexible module. Background Technology

[0002] LED display flexible modules can be divided into indoor and outdoor flexible modules according to their application scenarios. Outdoor flexible modules include a flexible back cover and an LED light board. During production, the flexible back cover is first installed on the back of the LED light board, so that the edge of the flexible back cover surrounds the four sides of the LED light board. Then, the front and exposed back of the LED light board are potted with glue to achieve a waterproof protection effect.

[0003] However, due to the shape of the soft module itself and the influence of outdoor environmental factors, after a long period of use, the LED light panel of the outdoor soft module is prone to lifting and detaching from the soft base shell. The LED light panel is easily corroded by rainwater, and the waterproof effect is not ideal. Utility Model Content

[0004] (a) Technical problems to be solved In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an integrated outdoor LED flexible module, which solves the technical problems of complex structure and unsatisfactory waterproof effect of existing outdoor flexible modules.

[0005] (II) Technical Solution To achieve the above objectives, the main technical solutions adopted by this utility model include: This utility model embodiment provides an integrally molded outdoor LED flexible module, including an LED light board and a light-transmitting colloid. The light-transmitting colloid is integrally molded with the LED light board, covering the entire front, side, and back surfaces of the LED light board. The front surface of the LED light board is covered with LED beads, and the back surface is fitted with connectors. The light-transmitting colloid wraps around the LED beads and connectors. The rear end of the connector extends out of the light-transmitting colloid and is plugged into a cable connector to provide power and signals to the LED flexible module.

[0006] Optionally, the translucent adhesive has a waterproof inclined step at the connector position, and the cable joint is wrapped in a frustum shape to fit tightly with the waterproof inclined step.

[0007] Optionally, raised ribs are provided at both plane positions of the waterproof inclined step, and the raised ribs are set along the waterproof inclined step to form a ring structure.

[0008] Optionally, the raised ribs and the translucent colloid are integrally molded.

[0009] Optionally, a waterproof sleeve is integrally formed around the connector by a light-transmitting colloid. The inner wall of the waterproof sleeve is inclined and has at least one limiting boss. The cable connector has an annular limiting groove that matches the limiting boss. The cable connector is inserted into the waterproof sleeve to form an interference fit.

[0010] Optionally, the front of the light-transmitting colloid is a flat plane, or the front of the light-transmitting colloid has a cap above each LED bead.

[0011] Optionally, the thickness of the light-transmitting colloid on the front side of the LED light panel is set to 0.2mm to 0.4mm, and the thickness on the side wall of the LED light panel is set to 0.2mm to 1mm.

[0012] Optionally, the LED light panel also includes copper pillars and a magnet assembly. The copper pillars are welded to the back of the LED light panel and placed in a light-transmitting colloid. The magnet assembly is threadedly connected to the copper pillars, and the light-transmitting colloid forms a clearance at the position of the magnet assembly.

[0013] Optionally, the back of the light-transmitting colloid is provided with several vertical strip grooves, which extend through the opposite sides of the light-transmitting colloid.

[0014] Optionally, the connector is a signal socket and a power socket, and the corresponding cable is a signal cable and a power cable; or the connector is a power and signal combo socket, and the corresponding cable is a power and signal combo cable.

[0015] (III) Beneficial Effects The beneficial effects of this utility model are: 1. The present invention relates to an integrated outdoor LED soft module, which places the LED light board inside a silicone mold and wraps it with a light-transmitting colloid to form an integrated structure. The light-transmitting colloid replaces the existing soft bottom shell and can waterproof the LED light board as a whole. It eliminates the need to set waterproof potting layers on the front and back of the LED light board. Compared with the prior art, it solves the technical problems of complex structure and unsatisfactory waterproof effect of existing outdoor soft modules.

[0016] 2. Because the light-transmitting colloid completely wraps the front, side and back of the LED light panel, the two form an integrated structure, achieving overall waterproofing of the LED light panel. The waterproofing effect is good, and the LED light panel will not peel off, causing the waterproofing to fail.

[0017] 3. The translucent adhesive has a waterproof sloping step at the connector position, and the cable joint is wrapped in a frustum shape to fit tightly with the waterproof sloping step, making it easier to plug and unplug the connector and cable joint, and improving the waterproof effect.

[0019] 5. The front of the LED light panel is wrapped with a light-transmitting colloid, which has excellent transparency. A silicone mold is used to form the LED light panel and the light-transmitting colloid into one piece, resulting in high consistency in the quality of the soft module.

[0020] 6. The back of the LED light panel is equipped with a magnetic assembly, which allows for the installation of soft modules using a magnetic mounting method, making installation and removal convenient.

[0021] 7. The front of the translucent colloid can be set as a flat surface, suitable for outdoor irregularly shaped soft modules, or it can be fitted with a brim, suitable for outdoor transparent screens, outdoor fixed screens, or outdoor rental screens, etc., to block sunlight and rain outdoors. Whether to add a brim depends on actual needs. The brim is made of silicone mold in one piece, ensuring good consistency.

[0022] 8. The waterproof inclined steps of the connector are equipped with raised ribs to ensure a tight fit between the connector and the cable joint, resulting in better waterproofing. Attached Figure Description

Detailed Implementation

[0025] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper" and "lower" are used interchangeably with... Figure 6 Using the orientation as a reference, the direction where the brim 21 is located is the "front", and the direction where the signal wire connector 5 is located is the "back".

[0026] This utility model proposes an integrated outdoor LED flexible module, comprising an LED light board and a light-transmitting colloid. The light-transmitting colloid is integrally formed with the LED light board, covering the entire front, side, and back surfaces of the LED light board. LED beads are laid on the front of the LED light board, and connectors are attached to its back. The light-transmitting colloid encapsulates the LED beads and connectors, with the rear end of the connector extending from the light-transmitting colloid and engaging with a cable connector to supply power and signals to the LED flexible module. Compared to existing technologies, by placing the LED light board within a silicone mold and completely encapsulating it with the light-transmitting colloid to form an integrated structure, the light-transmitting colloid replaces the existing soft base shell and provides overall waterproofing for the LED light board. This eliminates the need for waterproof potting layers on both the front and back of the LED light board, solving the technical problems of complex structures and insufficient waterproofing in existing outdoor flexible modules.

[0027] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0028] Example 1, see Figure 1 , Figure 2 and Figure 5 This embodiment 1 provides an integrally molded outdoor LED flexible module, including an LED light panel 1 and a light-transmitting colloid 2. The light-transmitting colloid 2 is integrally molded with the LED light panel 1, covering the entire front, sides, and back of the LED light panel 1. The material of the light-transmitting colloid 2 is usually a transparent or semi-transparent soft rubber, such as silicone or PVC, which can transmit light and meet the bending requirements of the flexible module. The light-transmitting colloid 2 provides waterproof and impact-resistant protection for the LED light panel 1.

[0029] See Figures 1 to 5The LED light board 1 includes a PCB circuit board 12. LED beads 11 are laid on the front of the PCB circuit board 12, and a power socket 14 and two signal sockets 13 are soldered to the back. A light-transmitting colloid 2 encapsulates the LED beads 11, the power socket 14, and the signal sockets 13. The power socket 14 is located in the middle of the LED light board 1, extending from the light-transmitting colloid 2 and connecting to a power cable connector 6 to provide DC power to the flexible module. The two signal sockets 13 are respectively located on both sides of the power socket 14, one for receiving signals and the other for outputting signals. The rear end of the signal socket 13 extends from the light-transmitting colloid 2 and connects to a signal cable connector 5.

[0030] In actual production applications, a power connector 14 and a signal connector 13 can be replaced with a power-signal connector 14, and the corresponding cable can be replaced with a power-signal connector 13. In other words, the connector can be either power connector 14 and signal connector 13, or a power-signal connector 14.

[0031] See Figures 3 to 6 As a feasible solution, the light-transmitting colloid 2 has waterproof inclined steps 22 at both the power socket 14 and the signal socket 13. The waterproof inclined steps 22 are arranged around the corresponding power socket 14 or signal socket 13, forming a frustum shape. The coating of the power cable connector 6 and the signal cable connector 5 is also frustum shaped, tightly fitting with the waterproof inclined steps 22. Specifically, the power cable connector 6 is inserted into the power socket 14 and connected to a threaded post welded to the back of the LED light board 1 by bolts, so that the power cable connector 6 and the waterproof inclined steps 22 are tightly fitted. The signal cable connector 5 is inserted into the signal socket 13 and connected to a threaded post welded to the back of the LED light board 1 by bolts, so that the signal cable connector 5 and the waterproof inclined steps 22 are tightly fitted.

[0032] See Figure 5 The waterproof inclined step 22 has raised ribs 221 on both planes. These ribs 221 are arranged along the waterproof inclined step 22, forming two concentric rings that surround the power socket 14 and the signal socket 13. When the signal socket 13 is plugged into the signal cable connector 5, the two raised ribs 221 surrounding the signal socket 13 are pressed together with the rubber coating of the signal cable connector 5, forming a tight fit. This prevents rainwater from seeping in from the connection point of the signal socket 13, providing double waterproofing and excellent waterproofing performance. Similarly, when the power socket 14 is plugged into the power cable connector 6, the two raised ribs 221 surrounding the power socket 14 are pressed together with the rubber coating of the power cable connector 6, achieving double waterproofing.

[0033] See Figure 3 and Figure 6In actual production applications, the front surface of the light-transmitting colloid 2 can be designed as a flat plane, suitable for outdoor irregularly shaped soft modules; or the front surface of the light-transmitting colloid 2 can have a brim 21 corresponding to each LED bead 11, suitable for outdoor transparent screens, outdoor fixed screens, or outdoor rental screens, etc., to block sunlight and rain outdoors. Whether to set the brim 21 can be selected according to actual needs. The brim 21 is integrally molded with a silicone mold, ensuring good consistency. The brim 21 is a strip-shaped protrusion on the front surface of the light-transmitting colloid 2, and adjacent brims 21 are not connected to each other.

[0034] The thickness of the light-transmitting colloid 2 on the front side of the LED light panel 1 is generally set to 0.2mm to 0.4mm. The soft module has good transparency; the smaller the thickness of the light-transmitting colloid 2 on the front side of the LED light panel 1, the higher the light transmittance. The thickness of the light-transmitting colloid 2 on the sides of the LED light panel 1 is generally set to 0.2mm to 1mm. Because the light-transmitting colloid 2 completely covers the front, sides, and back of the LED light panel 1, forming an integrated structure, it achieves overall waterproofing of the LED light panel 1. This results in good waterproofing performance and prevents the LED light panel 1 from warping or detaching, thus avoiding waterproofing failure.

[0035] See Figure 1 and Figure 3 A copper pillar 3 is welded to the back of the LED light panel 1 and placed in a light-transmitting colloid 2. The light-transmitting colloid 2 forms a clearance position at the corresponding position of the copper pillar 3. The magnet assembly is placed in the clearance position and connected to the copper pillar 3. The magnet assembly includes a magnet base and a magnet body 4. The magnet base is threadedly connected to the copper pillar 3, and the magnet body 4 is mounted on the magnet base. The flexible module can be magnetically attached to the screen mounting bracket, making it easy to install and remove.

[0036] To enhance the flexibility of the flexible module, the back of the light-transmitting colloid 2 is provided with vertical strip-shaped grooves 23. The strip-shaped grooves 23 extend and penetrate through the opposite sides of the light-transmitting colloid 2. Multiple strip-shaped grooves 23 are arranged side by side at intervals.

[0037] In actual production applications, the raised ribs 221 and the brim 21 are integrally formed with the light-transmitting colloid 2. That is to say, when the LED light panel 1 is completely wrapped with the light-transmitting colloid 2 in the silicone mold, the waterproof inclined step 22, the raised ribs 221, the brim 21, the strip groove 23 and other structures of the light-transmitting colloid 2 are formed at the same time, and the production is completed in one step.

[0038] By placing the LED light panel 1 inside a silicone mold and completely encasing it in the light-transmitting colloid 2 to form an integrated structure, compared to existing technologies, the light-transmitting colloid 2 replaces the soft base shell. The soft module no longer needs to be installed with a soft base shell. Furthermore, since the light-transmitting colloid 2 provides overall waterproofing for the LED light panel 1, there is no need to set waterproof potting layers on the front and back of the LED light panel 1. The soft module structure of this application is simpler, the production process and flow are simpler, and the production efficiency is higher. It achieves overall waterproofing of the LED light panel 1, with better waterproofing effect, and solves the technical problems of complex structure and unsatisfactory waterproofing effect of existing outdoor soft modules.

[0039] During production, LED beads 11 are mounted on the front side of the PCB circuit board 12, and threaded pillars, signal sockets 13, power sockets 14, and copper pillars 3 are soldered to the back side. After the magnet assembly is installed, the LED light board 1 is assembled. The LED light board 1 is then placed in a silicone mold and covered with a light-transmitting colloid 2 to obtain an integrated soft module.

[0040] Example 2, see Figure 7 and Figure 8 Unlike Embodiment 1, in Embodiment 2, the light-transmitting colloid 2 is integrally formed with a waterproof sleeve 24 around the connector. The inner wall of the waterproof sleeve 24 has a limiting boss 241 along its circumferential direction. The cable connector has an annular limiting groove that matches the limiting boss 241. The cable connector is inserted into the waterproof sleeve 24, and the two are interference-fitted (i.e., tight-fitted), achieving waterproof connection between the connector and the cable connector. The tight fit between the limiting boss 241 and the annular limiting groove provides both a waterproof seal and a securing effect, preventing the cable connector from loosening or falling off.

[0041] In some feasible solutions, the inner wall of the waterproof sleeve 24 is inclined, and at least one limiting boss 241 is provided, usually one or two, to further enhance the waterproof capability of the connector and cable joint.
