TECHNICAL FIELD
[0001] The utility model relates to a kind of damp-proof reinforcing face shield, especially a kind of damp-proof reinforcing face shield for LED movie screen lamp plate. BACKGROUND
[0002] At present, the LED movie screen of cinema mainly includes several LED modules installed in stack, and the LED module includes an LED box body, and a lamp plate is installed on each sub-grid formed on the LED box body, and the lamp plate includes a circuit board and LED lamp beads on the circuit board. The existing lamp plate is usually provided with a face shield. The face shield includes a base plate, and a plurality of holes are formed in the base plate corresponding to the LED lamp beads. The face shield is buckled on the lamp plate, and the LED lamp beads are arranged through the holes in the face shield. From the actual use effect, this face shield can only enhance the contrast effect, and has no protection effect on the LED lamp beads. After long-term use, especially in the humid and rainy areas in the south, the surface-mounted LED lamp beads have the risk of being corroded and de-soldered by moisture, and the LED lamp beads also have the risk of being deformed and falling off by collision. For the above-mentioned situation, the common solution is to fill glue in the gap around the LED lamp beads to prevent moisture and reinforce, but this method is time-consuming and laborious, and individual lamp beads cannot be replaced during maintenance, so the entire lamp plate is often replaced, which increases the maintenance cost.

[0006] The utility model has the following advantages:
[0007] The damp-proof reinforcing face shield for LED movie screen lamp plate effectively prevents moisture and reinforces the LED lamp beads on the lamp plate, avoids the problems of corrosion and de-soldering of the LED lamp beads due to moisture, avoids the problems of deformation and falling off of the LED lamp beads due to collision, has good protection effect, saves time and effort during installation, disassembly and maintenance, has low cost, and is suitable for promotion.

[0014] As Figures 1 to 6 shown, the utility model provides a kind of moisture-proof reinforced mask of LED movie screen lamp panel, including the substrate 10 of plastic material, multiple square openings 11 are set on substrate 10, each opening 11 position protrudes the protective cover 20 of certain elasticity of plastic material, wherein: protective cover 20 is four-prism table (exactly be positive four-prism table), upper and lower through open mouth;Protective cover 20 is used to be wrapped on the LED lamp bead 31 of lamp panel 30, and LED lamp bead 31 is wrapped around.
[0015] In actual design, each opening 11 is arranged according to regular matrix form, and the arrangement of each opening 11 is consistent with the arrangement of each LED lamp bead 31 on lamp panel 30.
[0016] As Figure 2 , bottom open mouth 24 of protective cover 20 and fixed opening 11 is greater than its top open mouth 23, i.e., protective cover 20 is small in upper, large in lower structure, the area of bottom open mouth 24 is equal to or slightly greater than the cross-sectional area of LED lamp bead 31, and the area of top open mouth 23 is slightly less than the cross-sectional area of LED lamp bead 31, so that protective cover 20 can be wrapped on LED lamp bead 31 passing through opening 11, so that protective cover 20 is tightly attached to the side surface of LED lamp bead 31, and LED lamp bead 31 is tightly wrapped by using the elastic deformation characteristics thereof.
[0017] Further, the height of protective cover 20 is slightly lower than the height of LED lamp bead 31, so as not to affect the normal light emission of LED lamp bead 31.
[0018] As Figure 3An inwardly extending edge 110 is formed by the opening 11. The edge 110 is lower than the top surface 101 of the substrate 10, and can be lower than or flush with the bottom surface 102 of the substrate 10. The bottom opening 24 of the protective cover 20 is fixed to the edge 110. The design of the edge 110 increases the robustness of the protective cover 20.
[0019] like Figure 2 and Figure 5 A reinforcing block 21 is formed around each of the four sides of the protective cover 20, and each reinforcing block 21 is fixed to the edge of the opening 11 of the substrate 10. The design of the reinforcing block 21 further increases the robustness of the protective cover 20, and firmly connects it to the substrate 10.
[0020] like Figure 2 The protective cover 20 includes four inclined walls 22, each of which is correspondingly arranged with the four sides of the opening 11. Adjacent inclined walls 22 are connected by a rounded corner 201. This design reduces the chance of the protective cover 20 damaging the LED beads 31.
[0021] In actual manufacturing, the protective cover 20 is integrally molded onto the opening 11 of the substrate 10 using an injection molding process. In actual processing, the substrate 10 is first injection molded, and then the protective cover 20 is injection molded onto the opening 11 of the substrate 10. This processing method allows for mass production, is simple in process, and has low cost.
[0022] In use, align the lamp board 30 with the LED beads 31 facing upwards. Then, apply adhesive to the corresponding positions (e.g., the four corners) on the bottom surface 102 of the substrate 10. Next, align each opening 11 of the moisture-proof reinforced face shield with each LED bead 31, and simultaneously press down on the substrate 10 of the moisture-proof reinforced face shield. The substrate 10 is then bonded and fixed to the circuit board 32 of the lamp board 30, while the LED beads 31 pass through the opening 11 and are encased by the protective cover 20. In practice, an auxiliary tool 40 (whose structure can be reasonably designed according to actual needs and is not limited, for example, using…) can be used. Figure 6 The auxiliary tool 40 is used to press the substrate 10 to achieve a compaction effect. Ultimately, the elastic deformation characteristic of the protective cover 20 tightly wraps around the LED beads 31, while the substrate 10 is tightly attached to the circuit board 32 covering the lamp board 30, covering the solder pins and pads on the circuit board 32 to achieve a sealing effect. The way the protective cover 20 tightly wraps around the LED beads 31 fills the gaps around them, reinforcing the LED beads 31 and preventing damage from accidental impacts, reducing deformation and detachment. At the same time, the way the protective cover 20 tightly wraps around the LED beads 31 effectively prevents moisture from entering and prevents oxidation of the solder joints.
[0023] In practical application, the size of the moisture-proof reinforced face shield can be reasonably designed, for example, a plurality of the moisture-proof reinforced face shields of the utility model can be installed on one lamp panel 30, of course, without limitation. Figure 4
[0024] The lamp panel 30 is a component in the art, which comprises a circuit board 32 and LED lamp beads 31 installed on the circuit board 32, and the LED lamp beads 31 are in the shape of a flat cuboid (cross section is square).
[0025] The utility model has the advantages of:
[0026] The moisture-proof reinforced face shield has good moisture-proof and reinforcing effects on the LED lamp beads on the lamp panel, avoids the problems of moisture corrosion and desoldering of the LED lamp beads, avoids the problems of deformation and falling of the LED lamp beads caused by collision, has good protection effect, saves time and effort in installation, disassembly and maintenance, has low cost, and is suitable for promotion.
[0027] The above is the preferred embodiment of the utility model and the technical principle used, for those skilled in the art, without departing from the spirit and scope of the utility model, any equivalent transformation, simple replacement and other obvious changes based on the technical scheme of the utility model, all belong to the protection scope of the utility model.
