Description

Technical Field

[0001] The present application relates to the technical field of outdoor display screens, and in particular to an outdoor LED display device. Background Art

[0002] With the continuous advancement of technology, LED screens have gained widespread application in various fields, including outdoor advertising and information dissemination, due to their advantages such as high brightness, low energy consumption, and long lifespan. Outdoor display devices must not only provide excellent display quality but also have a high level of protection to withstand various harsh environmental conditions. Therefore, designing an outdoor LED display device that can effectively improve its waterproof and dustproof performance is of great significance.

[0003] In order to increase the waterproof and dustproof performance, outdoor LED display devices under the existing technology usually cover the LED lamp beads welded to the lamp board with a large area of transparent potting glue to protect the LED lamp beads and avoid aging, abnormal electrical performance and other problems caused by their exposure. Although the outdoor LED display device set up in this way can better protect the LED lamp beads, it also has many disadvantages. For example, it is not conducive to the subsequent modification and maintenance of some LED lamp beads, which will have a certain degree of impact on the display effect of the entire screen. Summary of the Invention

[0004] In order to overcome the above technical problems, the present application provides an outdoor LED display device.

[0005] This application provides an outdoor LED display device, which adopts the following technical solutions:

[0007] By adopting the above technical solution: not only can the LED lamp beads have a better dust and water proof effect and extend their service life, but also the LED lamp beads can be easily replaced and maintained.

[0008] Preferably, the light-transmitting cover comprises a plate body, a plurality of lampshades evenly distributed on the plate body, and glue holes arranged between adjacent lampshades; the plurality of lampshades are arranged to cover the corresponding LED lamp beads;

[0009] The surface of the light-transmitting cover is covered with a sealant for increasing the sealing performance between the light-transmitting cover and the light board, and the sealant in the sealant hole is fastened to the light board.

[0010] By adopting the above technical solutions, multiple lamp covers distributed on the surface of the board body can cover each LED lamp bead separately. At the same time, the sealing performance between the light-transmitting cover and the lamp board can be increased through the sealant. The setting of the lamp covers in the light-transmitting cover can effectively improve the display effect of the LED lamp beads, and at the same time, it can also prevent the sealant from directly covering the LED lamp beads, which affects the optical performance of the LED lamp beads and subsequent maintenance.

[0011] Preferably, the mask includes a cover plate, avoidance holes evenly distributed on the cover plate and sleeved on the lamp covers, and flanges arranged on opposite sides of the avoidance holes; the flanges are provided with mounting holes for fastening the mask to the lamp board.

[0012] By adopting the above technical solutions: installing the mask on the surface of the light-transmitting cover through the mounting holes can play a good protective role for the light-transmitting cover, extend its service life, and avoid premature aging.

[0013] Preferably, multiple lamp covers are exposed in the grooves between adjacent flanges, and the top surface of the flanges is higher than the top surface of the lamp covers; a textured surface for improving the display performance of the light-emitting component is arranged in the grooves.

[0014] By adopting the above technical solutions: since the top surface of the flange is higher than the top surface of the lamp cover, it can play a good protective role for the lamp cover, avoid damage to the lamp cover when the assembled light-emitting components are stacked on each other, and at the same time, the display performance of the light-emitting component can be further improved and the light emission uniformity can be increased through the textured surface arranged on the bottom surface of the groove.

[0015] Preferably, a plurality of support columns are arranged on the front surface of the bottom shell, and the light-emitting component is fastened to the support columns by screws.

[0016] By adopting the above technical solutions: it is not only convenient to install and fix the light-emitting component, but also the heat dissipation performance of the light-emitting component can be effectively improved through the support of a plurality of support columns, and the service life of the light-emitting component can be extended.

[0017] Preferably, a wire passing hole is formed in the middle of the bottom shell, and the wire passing hole is hermetically fastened to the power supply component through a sealing ring; the power supply component includes a power supply box, a wiring port arranged on the power supply box, and a power supply hermetically arranged in the power supply box through potting glue; a waterproof sealing ring for facilitating sealed connection with external components is also arranged on the reverse side of the bottom shell.

[0018] By adopting the above technical solutions: the power supply is hermetically sealed in the power supply box by potting glue, and then the power supply box is hermetically fastened to the bottom shell through a sealing ring, so as to further improve the waterproof performance of the power supply component.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. By arranging a light-emitting component on the front of the bottom shell and a power supply component on the back of the bottom shell, not only can the display performance of the outdoor display device be effectively improved, but also a good dustproof and waterproof effect can be achieved.

[0021] 2. By arranging a light-transmitting cover on the LED lamp beads to form a seal between it and the lamp board, and then covering the mask on the light-transmitting cover, the dustproof and waterproof performance of the LED lamp beads can be better improved, and at the same time, it is convenient to replace and maintain the LED lamp beads subsequently.

[0038] The following further describes the present application in detail with reference to the accompanying drawings.

[0039] Refer to Figures 1 to 3 As shown, this embodiment provides an outdoor LED display device, including a bottom case 1, a light-emitting component 2 disposed on the front surface of the bottom case 1, and a power supply component 3 disposed on the back surface of the bottom case 1 and electrically connected to the light-emitting component 2; wherein, the light-emitting component 2 includes a lamp board 21 fastened to the bottom case 1, LED lamp beads 22 evenly distributed on the lamp board 21, a light-transmitting cover 23 covering the LED lamp beads 22 and hermetically arranged with the lamp board 21, and a face mask 24 covering the light-transmitting cover 23.

[0040] For the outdoor LED display device designed with the above structure, the multiple LED lamp beads 22 evenly distributed on the lamp board 21 are hermetically covered by the light-transmitting cover 23, which can not only provide a good waterproof and dustproof effect on the LED lamp beads 22, but also improve the overall display effect of the outdoor LED display device; in addition, the face mask 24 covering the light-transmitting cover 23 can provide a good protection for the light-transmitting cover 23, and also facilitate the subsequent replacement or maintenance of the LED lamp beads 22.

[0041] Specifically, as shown in Figure 2 and Figure 3 In order to facilitate the installation and fixation of the above light-emitting component 2 and also facilitate the heat dissipation of the light-emitting component 2, a plurality of support columns 11 are distributed on the inner wall surface of the bottom case 1. During installation, the lamp board 21 welded with the LED lamp beads 22 can be first placed on the plurality of support columns 11, and then the light-transmitting cover 23 is covered on the lamp board 21 and sealed with the lamp board 21 through a sealant 4. After the sealant 4 layer is cured, the face mask 24 is fixed to the surface of the light-transmitting cover 23 to protect the light-transmitting cover 23.

[0042] Preferably, the bottom case 1 can be integrally formed by injection molding. In order to facilitate the wiring when the light-emitting component 2 is electrically connected to the power supply component 3, a wire passing hole is also opened in the middle of the bottom case 1. When installing the power supply component 3, the sealing performance after the connection between the power supply component 3 and the bottom case 1 can be improved by adding a sealing ring 5 at the edge of the wire passing hole.

[0043] Furthermore, preferably, the above power supply component 3 includes a power supply box 31, a wiring port disposed on the power supply box 31, and a power supply hermetically arranged in the power supply box 31 through potting glue. The power supply box 31 and the bottom case 1 are fastened by screws. In this way, the overall waterproof and dustproof performance of the outdoor LED display device can be effectively improved.

[0044] In addition, when the outdoor LED display device assembled in the above manner is connected to an external component, in order to further improve the sealing performance at the connection, preferably, a waterproof sealing ring 6 for facilitating sealed connection with the external component is further provided on the reverse side of the bottom case 1. The waterproof sealing ring 6 surrounds the periphery of the power supply assembly 3. After the bottom case 1 is hermetically connected to the external component through this waterproof sealing ring 6, the power supply assembly 3 can be in a relatively sealed cavity, further improving the waterproof and dustproof levels of the power supply assembly 3.

[0045] Combined Figures 4 to 7 As shown, the above-mentioned light-transmitting cover 23 includes a plate body 231, a plurality of lamp shades 232 evenly distributed on the plate body 231, and glue holes 233 provided between adjacent lamp shades 232. The light-transmitting cover 23 designed with this structure can be integrally injection-molded, and some optical features beneficial to improving the display effect of the outdoor display device can be added on the inner surface or the outer surface of the lamp shade 232 according to design requirements.

[0046] When installing the light-transmitting cover 23, the light-transmitting cover 23 can be first covered on the lamp board 21 so that the lamp shades 232 correspond to the LED lamp beads 22 below. Then, a sealing glue 4 for increasing the sealing performance between the light-transmitting cover 23 and the lamp board 21 is covered on the surface of the light-transmitting cover 23. A part of the covered sealing glue 4 will flow into the gap between the light-transmitting cover 23 and the lamp board 21 through the glue holes 233. In this way, after the sealing glue 4 is cured, the lamp board 21 and the light-transmitting cover 23 are hermetically fastened together. This can not only effectively improve the dustproof and waterproof performance of the LED lamp beads 22, but also prevent the sealing glue 4 from directly covering the surface of the LED lamp beads 22, which may have a certain impact on the light-emitting performance of the LED lamp beads 22.

[0047] After the above-mentioned sealing glue 4 is cured, the face mask 24 can be fixed to the surface of the light-transmitting cover 23 covered with the sealing glue 4. In order to enable the face mask 24 to play a certain protective role for the underlying light-transmitting cover 23 and prevent it from aging rapidly due to wind, sun and rain outdoors, preferably, the face mask 24 includes a cover plate 241, avoidance holes 242 evenly distributed on the cover plate 241 and sleeved on the lamp shades 232, and flanges 243 provided on opposite sides of the avoidance holes 242; mounting holes 244 for fastening the face mask 24 to the lamp board 21 are provided on the flanges 243. With the face mask 24 designed with this structure, during installation, the avoidance holes 242 can be correspondingly sleeved on the lamp shades 232, and then it can be locked to the corresponding support posts 11 on the bottom case 1 with screws through the mounting holes 244, thereby forming a shield and protection for the underlying light-transmitting cover 23; and if the LED lamp beads 22 need to be replaced or maintained later, it can also be conveniently disassembled.

[0048] After the light-emitting component 2 is assembled in the above manner, multiple lamp covers 232 are all exposed outside the bottom surface of the groove through the avoidance holes 242. Since the top surfaces of the flanges 243 on both sides of the groove are higher than the top surface of the lamp cover 232, when the outdoor LED display devices are stacked on each other, the lamp cover 232 will not be worn, and thus the light-transmitting cover 23 below can be better protected effectively.

[0049] In addition, in order to better improve the light-emitting uniformity of the entire light-emitting surface and optimize the overall display effect of the light-emitting surface, ribbed surfaces 245 are further provided on both sides of the avoidance holes 242 in the bottom surface of the groove. As a preference, the ribbed surfaces 245 are arranged in a serrated shape.

[0050] The implementation principle of the embodiment of the present application is as follows: For the outdoor LED display device designed with the above structure, during assembly, the light-transmitting cover 23 can be first covered on the lamp board 21, and the lamp cover 232 is made to correspond to the LED lamp beads 22 below. Then, the sealant 4 is covered on the surface of the light-transmitting cover 23. A part of the covered sealant 4 will flow into the gap between the light-transmitting cover 23 and the lamp board 21 through the glue holes 233, and then the light-transmitting cover 23 and the lamp board 21 are hermetically fastened. After the sealant 4 is cured, the mask 24 can be fixed to the surface of the light-transmitting cover 23 covered with the sealant 4. The outdoor LED display device assembled in this way can achieve a good dust-proof and waterproof effect on the LED lamp beads 22 through the seal between the light-transmitting cover 23 and the lamp board 21. At the same time, through the setting of the mask 24, the light-transmitting cover 23 can be better protected. Moreover, arranged in this way, when the LED lamp beads 22 are abnormal later, the mask 24 and the light-transmitting cover 23 can be conveniently disassembled and assembled, and then the LED lamp beads 22 can be conveniently maintained.

[0051] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
