[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figure 1-6 As shown, this utility model provides a waterproof LED lightbox. The lightbox is ingeniously designed and has good waterproof performance and light projection effect, making it suitable for lighting and advertising displays in various outdoor or humid environments.

[0032] This waterproof LED lightbox mainly consists of a cover 1 and a bottom box 2 with an open top. The cover 1 is installed at the open end of the bottom box 2 in a specific way, thereby forming a sealed cavity inside the bottom box 2. Multiple LED light sources 3 for projecting light are installed within this sealed cavity.

[0033] The edge of the cover 1 is designed with a downwardly extending extension 101. When the cover 1 is installed with the bottom box 2, this extension 101 fits tightly against the outside of the bottom box 2.

[0034] To enhance waterproofing, multiple coaxially arranged first waterproof rubber rings 4 are provided between the outer side of the base box 2 and the extension 101. These first waterproof rubber rings 4 are fixed by limiting grooves 5 formed on the outer side of the base box 2 and the extension 101, ensuring that they can be stably held in the correct position and play an effective waterproofing role. During connection, in order to prevent the first waterproof rubber rings 4 from falling off, the first waterproof rubber rings 4 are arranged parallel to the direction of the central axis of the base box 2, and the first waterproof rubber rings 4 are fixed in the limiting grooves 5 formed on the base box 2.

[0035] To ensure a tight connection between the cover 1 and the bottom box 2, the extension 101 is aligned with the bottom of the bottom box 2 after extension and is locked in place by a plurality of first locking elements 8 (such as screws).

[0036] One end of the opening of the base box 2 is fitted with a nameplate 6, which has a sealing opening. When the cover 1 is assembled with the base box 2, the nameplate 6 can fit tightly against the bottom of the cover 1, improving stability. To further enhance the sealing performance, a second waterproof rubber ring 7 is fitted on the outside of the nameplate 6 to seal against one end of the opening of the base box 2.

[0037] To improve the stability and sealing of the nameplate 6, a coaxially arranged groove 9 is provided at one end of the opening of the base box 2, and the nameplate 6 is placed in this groove 9. The nameplate 6 is sealed to the inner wall of the groove 9 by the second waterproof rubber ring 7 on its side, thereby further preventing moisture from seeping into the interior of the light box.

[0038] A light guide plate 10, which is attached to the bottom of the nameplate 6, is also installed inside the slot 9. This light guide plate 10 helps to project the light from the LED light source 3 onto the nameplate 6 more evenly, thereby improving the overall lighting effect. The nameplate 6 and the light guide plate 10 are fixed together in the slot 9 by multiple second locking members 11.

[0039] The LED light sources 3 are distributed and fixed at the bottom of the base box 2, and all the LED light sources 3 project light towards the bottom of the nameplate 6. This design ensures that the light can be evenly distributed on the nameplate 6, displaying clear images or text.

[0040] The base box 2 houses a circuit board 12 that connects all the LED light sources 3. Additionally, a power supply unit connected to the circuit board 12 is required. These components together constitute the electrical system of the light box, providing a stable power supply to the LED light sources 3.

[0041] To further improve the utilization of light, a reflector 13 is provided above the circuit board 12. This reflector 13 has holes 1301 that expose the corresponding LED light source 3, and can reflect the light emitted by the LED light source 3 so that it is projected onto the nameplate 6 more concentratedly.

[0042] The cover 1 has a transparent area 102 in the middle that allows light to pass through to the inside of the cavity. This transparent area 102 allows the observer to clearly see the image or text on the nameplate 6 from the outside, while maintaining the overall aesthetics of the lightbox.

[0043] To facilitate the fixing and installation of the light box, the base box 2 has a mounting slot 14 for wall mounting on the side away from the cover 1. These mounting slots 14 allow users to securely wall mount the light box to a wall or other flat surface using screws or other fasteners.

[0044] Compared with traditional technologies, the LED lightbox provided by this technical solution effectively prevents the intrusion of external moisture and humidity by setting a downwardly extending portion 101 on the edge of the cover 1 and setting several first waterproof rubber rings 4 between the outer side of the base box 2 and the extension portion 101, while using limiting grooves 5 for fixation. In addition, the second waterproof rubber ring 7 fitted on the outer side of the nameplate 6 further enhances the sealing of the opening end of the base box 2, thereby ensuring the dryness and safety of the LED light source 3 environment inside the entire lightbox and extending the service life of the lightbox.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
