[0024] Lightbox advertising display equipment is a type of device used for advertising. It can be an LCD screen, LED screen, OLED screen, etc. It can display various types of advertising content and is typically installed in commercial spaces, public places, and on public transportation to display various advertisements. However, in current technology, most lightbox advertising display equipment requires a large display surface, and to ensure the display effect, the light on the display surface must be kept uniform. Therefore, please refer to... Figure 1 The existing lightbox advertising display equipment has multiple light sources arranged in a 10' pattern. 12’ However, multiple light sources12’ This will inevitably increase the complexity and production cost of the 10' lightbox advertising display equipment.

[0025] To address the aforementioned problems, this disclosure provides a lightbox advertising display device. The lightbox advertising display device of this disclosure will be described below with reference to the accompanying drawings.

[0026] Please refer to the reference. Figure 2 and Figure 3 , Figure 2 This is a structural schematic diagram of a lightbox advertising display device provided in an embodiment of this application. Figure 3 This is a schematic diagram of the structure of a light guide plate for a lightbox advertising display device provided in an embodiment of this application. This disclosure provides a lightbox advertising display device 10, including a light-emitting device 1, a light-transmitting plate 2, and a light guide plate 3. The light-transmitting plate 2 is disposed on one side of the light-emitting device 1, allowing light emitted from the light-emitting device 1 to pass through the light-transmitting plate 2. The light guide plate 3 is disposed between the light-emitting device 1 and the light-transmitting plate 2, enabling the light emitted from the light-emitting device 1 to be evenly diffused over a larger area.

[0027] The light-emitting device 1 includes a printed circuit board 11 and a light source 12. The light source 12 is mounted on the printed circuit board and is located between the printed circuit board and the light guide plate 3. The printed circuit board 11 supplies power to the light source 12, which emits light to display advertisements. Optionally, the light source 12 can be an LED light.

[0028] The light-transmitting plate 2 can be either a flat or curved plate, depending on the specific requirements. The material of the light-transmitting plate 2 can be one or more of plexiglass, polycarbonate, copolyester, and acrylic. Plexiglass is a common material for light guide plates 3, possessing excellent light transmission and uniform optical properties; polycarbonate is a material with high strength, high impact strength, high transparency, good electrical properties, weather resistance, and heat resistance, suitable for manufacturing large-sized light-transmitting plates 2; copolyester is a new type of transparent engineering plastic with high transparency, high impact resistance, and high chemical resistance; acrylic has excellent light transmission and weather resistance. Due to their inherent excellent properties, these materials can be used to manufacture light guide plates 2 for various scenarios. Alternatively, the material of the light guide plate 3 can also be one or more of plexiglass, polycarbonate, copolyester, and acrylic.

[0029] Optionally, the surface of the light-transmitting plate 2 away from the light guide plate 3 and the surface of the light guide plate 3 close to the light-transmitting plate 2 are both matte. The matte design can effectively resist fingerprint residue, keep the material fresh for a long time, and make it exhibit excellent anti-reflective performance in strong light environment, ensuring that the displayed content can be clearly seen from any angle.

[0030] In some optional embodiments, the light guide plate 3 includes a first end 31 near the light-transmitting plate 2 and a second end 32 near the light source 12. The size of the light-transmitting plate 2 gradually decreases along the direction from the first end 31 to the second end 32. Light emitted from the light source 12 first enters the smaller second end 32, propagates along the interior of the light guide plate 3, and exits at the larger first end 31, allowing the light to be uniformly directed towards the light-transmitting plate 2. Optionally, the second end 32 includes a recess 321, where at least part of the light-emitting portion of the light source 12 is placed. This facilitates the positioning and installation of the light-emitting device 1 and allows as much light as possible from the light source 12 to reach the light guide plate 3, improving light utilization.

[0031] In summary, the lightbox advertising display device 10 disclosed herein, by setting a light guide plate 3, evenly disperses the light emitted by the light-emitting device 1. The dispersed light is then emitted through the light-transmitting plate 2, thereby reducing the number of light-emitting devices 1 while maintaining uniform light in the lightbox advertising display device 10. This makes the structure of the lightbox advertising display device 10 simpler and reduces the manufacturing cost of the lightbox advertising display device 10.

[0032] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
