AI Technical Summary
[0003]然而，现有GOB+3D技术路线的艺术屏模组存在显著应用局限：其表面采用的喷绘工艺虽能实现装饰纹理，却会因墨层对光线产生散射与吸收，严重削弱LED发光均匀性与色彩表现力，导致点亮后显示效果大打折扣；更关键的是，喷绘层完全覆盖模组表面，使得单灯珠故障检测、维修等基础维护操作难以实施，若出现局部损坏往往需要整体更换模组，大幅推高了后期使用成本
[0012]与现有技术相比，本实用新型提供的一种具有面罩的LED模组，对面罩的表面进行清洁，然后在面罩的表面喷绘图层一(白墨层)，接着在图层一的表面喷绘UV胶，并通过395nm波长紫光照射，进行图层一的快速干燥，接着在图层一的表面喷绘图层二(彩色油墨层)，然后在图层二的表面喷绘UV胶，并通过395nm波长紫光照射，进行图层二的快速干燥，最后，将面罩与LED模组进行装配。可拆卸面罩的设计，使面罩与LED模组分离，实现了模块化设计，提升了可维修性。当LED模组或面罩损坏时，可独立更换，降低维护成本。双层喷墨结构(白墨底层+彩色油墨层)优化了色彩显示，避免了面罩底色对图案的影响。使用UV胶+395nm紫光固化技术，实现了墨水的快速干燥，提高了生产效率和图案耐久性，双层喷绘工艺确保了色彩准确性和一致性，尤其在复杂环境中。

Description
Technical Field
[0001] This utility model relates to LED module technology, specifically to an LED module with a face mask. Background Technology
[0002] The core value of LED art screens lies in their innovative and deep integration of "display function" and "decorative attribute." Based on LED display technology, they utilize customized surface treatment processes such as nano-optical layers, embossed textures, and colored printing to create natural or artistic textures on the module surface. Before power-on, they can display diverse decorative textures such as wood grain, marble, cement, and metallic finishes, seamlessly integrating with walls, shop windows, and background walls, becoming an organic component of the space's decoration. After power-on, they immediately switch to high-definition display mode, supporting diverse information outputs such as dynamic videos, static images, and interactive content, perfectly meeting the needs of scenario-based displays. This "dual-state intelligent switching" feature allows them to transcend the traditional single-tool attribute of LED screens, elevating them to a spatial aesthetic carrier that combines functionality and artistic expression.
[0003] However, existing art screen modules using the GOB+3D technology approach have significant limitations: while the inkjet printing process used on the surface can achieve decorative textures, the ink layer scatters and absorbs light, severely weakening the uniformity of LED light emission and color performance, resulting in a significant reduction in display effect after lighting up; more importantly, the inkjet layer completely covers the module surface, making it difficult to carry out basic maintenance operations such as individual LED fault detection and repair. If local damage occurs, the entire module often needs to be replaced, significantly increasing the later usage cost.
[0004] Based on this, the present invention provides an LED module with a face mask. Utility Model Content
[0005] To address the problems mentioned in the background art, this utility model provides an LED module with a detachable mask. The detachable mask design separates the mask from the LED module, achieving modular design and improving maintainability. When the LED module or mask is damaged, it can be replaced independently, reducing maintenance costs. The dual-layer inkjet structure (white ink base layer + colored ink layer) optimizes color display and avoids the influence of the mask's base color on the pattern. Using UV adhesive + 395nm ultraviolet light curing technology achieves rapid ink drying, improving production efficiency and pattern durability. The dual-layer inkjet process ensures color accuracy and consistency, especially in complex environments.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an LED module with a face mask, comprising an LED module and a face mask; the face mask is disposed on the LED module; the surface of the face mask is coated with a first layer, and a second layer is coated on the first layer.
[0007] Furthermore, the first layer is white ink, and the second layer is colored ink.
[0008] Furthermore, both the surfaces of Layer 1 and Layer 2 are coated with UV adhesive.
[0009] Furthermore, the face mask and the LED module are detachably connected.
[0010] Furthermore, the LED module has a pair of sleeves on its side, the mask has a pair of pads on its side, the pads are inserted into the sleeves, and the LED module has a locking member on its side for locking the pads and sleeves.
[0011] Furthermore, the locking component includes a vertical cover disposed on the side of the LED module. Two movable strips are slidably disposed inside the vertical cover, and racks are disposed on the opposite sides of the two movable strips. A gear is rotatably disposed inside the vertical cover, and the gear meshes with the two racks. Insert rods are disposed at the ends of the two movable strips that are far apart from each other, and the insert rods can be inserted into the insert pads. A push strip is slidably disposed on the top of the vertical cover, and the push strip is connected to one of the movable strips. An elastic element is also disposed inside the vertical cover, and the side end of the elastic element is connected to one of the movable strips.
[0012] Compared with existing technologies, this utility model provides an LED module with a face mask. The face mask surface is cleaned, then a first layer (white ink layer) is sprayed onto it. Next, UV adhesive is sprayed onto the first layer, and it is rapidly dried by irradiation with 395nm wavelength ultraviolet light. Then, a second layer (colored ink layer) is sprayed onto the first layer, followed by UV adhesive spraying and rapid drying by irradiation with 395nm wavelength ultraviolet light. Finally, the face mask is assembled with the LED module. The detachable face mask design allows for separation of the face mask and LED module, achieving modular design and improving maintainability. When the LED module or face mask is damaged, it can be replaced independently, reducing maintenance costs. The dual-layer inkjet structure (white ink base layer + colored ink layer) optimizes color display and avoids the influence of the face mask's base color on the pattern. The use of UV adhesive + 395nm ultraviolet light curing technology achieves rapid ink drying, improving production efficiency and pattern durability. The dual-layer printing process ensures color accuracy and consistency, especially in complex environments.
[0013] When assembling the face mask and LED module, align the insert pads on the face mask with the insert sleeves on the LED module, then push the two push rods. This moves one of the moving rods, and with the help of gears and racks, the two moving rods move closer to each other. This moves the corresponding insert rod out of the insert sleeve, allowing the corresponding insert pad to be inserted into the insert sleeve. When the insert pad is pushed, the spring telescopic rod is compressed. When the insert rod aligns with the perforation on the insert pad, the spring telescopic rod extends, allowing the insert rod to be inserted into the perforation on the insert pad, thus completing the assembly. For disassembly, simply push the push rod to separate the insert rod from the insert pad, and then remove the face mask. The cooperation of the insert sleeve, insert pad, and locking mechanism enables quick installation and removal of the face mask. The entire process requires no tools and can be completed by hand. The upright cover ensures that the insert rod is firmly inserted into the perforation of the insert pad, forming a stable multi-point lock. This connection method effectively resists vibration and accidental impacts, preventing the face mask from loosening or falling off during operation. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0023] As attached Figure 1 To be continued Figure 5 As shown:
[0024] Example 1:
[0025] This utility model provides an LED module with a face mask, including an LED module 1 and a face mask 2; the face mask 2 is disposed on the LED module 1; the surface of the face mask 2 is coated with a first layer 3, and a second layer 4 is coated on the first layer 3.
[0026] like Figure 4 As shown, layer 3 is white ink with a concentration of 100%, and layer 4 is colored ink.
[0027] Specifically, UV glue is sprayed onto the surfaces of both Layer 3 and Layer 4.
[0028] Specifically, the mask 2 and the LED module 1 are detachably connected, and the mask 2 and the LED module 1 can be detachably connected by a bolt structure.
[0029] Specifically, first, the surface of mask 2 is cleaned, then layer 3 (white ink layer) is sprayed onto the surface of mask 2. Next, UV adhesive is sprayed onto the surface of layer 3 and irradiated with 395nm wavelength ultraviolet light to quickly dry layer 3. Then, layer 4 (colored ink layer) is sprayed onto the surface of layer 3, then UV adhesive is sprayed onto the surface of layer 4 and irradiated with 395nm wavelength ultraviolet light to quickly dry layer 4. Finally, mask 2 is assembled with LED module 1.
[0030] The design with an optional mask 2 separates the mask 2 from the LED module 1, achieving modular design and improving maintainability. When either the LED module 1 or the mask 2 is damaged, it can be replaced independently, reducing maintenance costs. The dual-layer inkjet structure (white ink base layer + colored ink layer) optimizes color display and avoids the influence of the mask 2's base color on the pattern. Using UV adhesive + 395nm ultraviolet light curing technology enables rapid ink drying, improving production efficiency and pattern durability. The dual-layer printing process ensures color accuracy and consistency, especially in complex environments.
[0031] Example 2:
[0032] This embodiment is a further optimization based on the first embodiment described above. The parts that are the same as those in the aforementioned technical solution will not be repeated here. Figures 2 to 5As shown, in order to better realize this utility model, the following arrangement is adopted. In this embodiment, a pair of inserts 6 are provided on the side of the LED module 1, and a pair of inserts 7 are provided on the side of the mask 2. The inserts 7 are inserted into the inserts 6, and a locking member 8 is provided on the side of the LED module 1 to lock the inserts 7 and the inserts 6.
[0033] like Figure 5 As shown, the locking component 8 includes a vertical cover 800 disposed on the side of the LED module 1. Two moving strips 801 are slidably disposed inside the vertical cover 800, and racks are provided on the opposite sides of the two moving strips 801. A gear 802 is rotatably disposed inside the vertical cover 800, and the gear 802 meshes with the two racks. Insert rods 803 are provided at the ends of the two moving strips 801 that are far apart from each other. The insert rods 803 can be inserted into the insert pads 7. A pusher 804 is slidably disposed on the top of the vertical cover 800 and is connected to one of the moving strips 801. An elastic element is also disposed inside the vertical cover 800, and the side end of the elastic element is connected to one of the moving strips 801. A slot for the pusher 804 to move is opened on the top of the vertical cover 800.
[0034] Specifically, the elastic element is a spring telescopic rod 5, which is installed inside the upright cover 800 through a sleeve. The telescopic end of the spring telescopic rod 5 is connected to the side end of a moving bar 801. Under the elastic force of the spring telescopic rod 5, the side end of the insertion rod 803 is arranged in the insertion sleeve 6. The side of the insertion pad 7 is provided with a through hole that matches the insertion rod 803.
[0035] Specifically, the inner wall of the cover 800 is provided with a guide groove for the sliding of the moving bar 801, and the moving bar 801 is slidably connected to the guide groove.
[0036] Specifically, when assembling the mask 2 and the LED module 1, the insert 7 on the mask 2 is aligned with the insert 6 on the LED module 1. Then, the two push bars 804 are pushed, causing one moving bar 801 to move. At this time, with the cooperation of the gear 802 and the rack, the two moving bars 801 will move closer to each other, causing the corresponding insert rod 803 to move out of the insert 6, and the corresponding insert 7 can be inserted into the insert 6. When the insert 6 is pushed, the spring telescopic rod 5 will be compressed. When the insert rod 803 is aligned with the through hole on the insert 7, the spring telescopic rod 5 will extend, so that the insert rod 803 is inserted into the through hole on the insert 7, thus completing the assembly. When disassembling, simply push the push bar 804 to separate the insert rod 803 from the insert 7, and then remove the mask 2.
[0037] This structural design enables rapid installation and removal of the face mask 2. The entire process can be completed by hand without any tools. The upright cover 800 ensures that the insertion rod 803 is firmly inserted into the perforation of the insertion pad 7, forming a stable multi-point locking. This connection method effectively resists vibration and accidental impact, preventing the face mask 2 from loosening or falling off during operation.
