Description

Technical Field

[0001] This utility model relates to the field of advertising light box technology, specifically to a splicable dual-color luminous letter advertising light box. Background Technology

[0002] With the continuous development of commercial advertising, dual-color illuminated advertising light boxes, as an efficient, intuitive, and visually impactful advertising medium, have gradually become the preferred advertising tool for various commercial venues, streetscapes, shopping malls, and other locations. Dual-color illuminated advertising light boxes can not only attract viewers' attention through different color combinations, but also adjust the colors according to specific advertising needs to achieve richer visual effects.

[0003] There are many types of dual-color illuminated advertising light boxes on the market. However, most of these light boxes are manufactured as a single unit after the supplier completes the size measurements. This single-unit structure makes them heavy and inconvenient to install. Furthermore, transporting these light boxes is also cumbersome, as they cannot be disassembled and reassembled into individual components for on-site installation, affecting both transportation and installation convenience. Therefore, we propose a modular dual-color illuminated advertising light box. Utility Model Content

[0004] The purpose of this invention is to provide a splicable dual-color luminous advertising light box to solve the defects mentioned in the background art.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] Please see Figures 1-5 This utility model provides a technical solution: a splicable dual-color luminous advertising light box, including multiple rectangular boxes 1. A vertically arranged guide post 10 is fixedly installed on one side of the top of the rectangular box 1. A stud 11 is fixedly installed at the top of the guide post 10. A guide rod 12 is fixedly installed on the other side of the top of the rectangular box 1. A guide hole 121 is provided in the end plate of the guide rod 12. The guide hole 121 is fitted onto the guide post 10. A nut 13 is threaded onto the stud 11. The size of the guide hole 121 is adapted to the size of the guide post 10. The nut 13 abuts against the upper surface of the guide rod 12, so that splicing and installation operations can be performed between two adjacent rectangular boxes 1, which is convenient to use.

[0028] Specifically, the rectangular box 1 has an exposed chamber 14 that is connected to the outside at both ends. The exposed chamber 14 contains a lamp bead substrate 19. A cover plate 2 is provided at the opening of one end of the exposed chamber 14. The cover plate 2 has multiple first light emission holes 21 and second light emission holes 22 that are connected to the outside. Multiple first lamp beads 191 and second lamp beads 192 are fixedly installed on the front side of the lamp bead substrate 19. The positions of the first lamp beads 191 and second lamp beads 192 correspond to the positions of the first light emission holes 21 and second light emission holes 22. The first lamp beads 191 and second lamp beads 192 are different colors to achieve dual-color light emission operation.

[0029] In this embodiment, rectangular grooves 15 are provided on both the front and rear side walls of the exposed chamber 14. A rectangular frame 20 is fixedly installed on the annular side of the cover plate 2. The rectangular frame 20 is located inside the rectangular groove 15 and is fixedly connected to the rectangular box 1. The size of the rectangular frame 20 is adapted to the size of the rectangular groove 15. The rectangular frame 20 is fixedly installed on the groove wall of the rectangular groove 15 by multiple fastening screws for stable assembly operation. At the same time, the use of fastening screws for fixing has the advantages of easy installation, disassembly and maintenance.

[0030] Specifically, fixing protrusions 16 are fixedly installed on the front and rear end walls of the four corners of the exposed chamber 14. The fixing protrusions 16 are fixedly installed on the external frame by fastening screws, so as to realize the fixed installation operation of the rectangular box 1.

[0031] Furthermore, the bottom wall of the exposed chamber 14 is provided with a wiring hole 17 that connects to the outside. The outer diameter of the wiring hole 17 is between 1.5cm and 4cm, which facilitates the introduction and organization of wires. This not only keeps the interior of the light box neat and beautiful, but also facilitates later maintenance and repair work.

[0032] In addition, multiple lamp mounting brackets 18 arranged linearly and at equal intervals are fixedly installed between the upper and lower walls of the exposed chamber 14. The lamp bead substrate 19 is fixedly installed on the lamp mounting brackets 18 by fastening screws, which facilitates the fixed installation operation.

[0033] When using the modular dual-color luminous advertising light box of this utility model, firstly, by cooperating with the guide post 10 and the guide hole 121, two adjacent rectangular boxes 1 are spliced ​​together. At this time, the guide post 10 is inserted into the guide hole 121 to ensure that the two boxes are accurately aligned. Then, the nut 13 is tightened until the nut 13 abuts against the upper surface of the guide rod 12 to complete the fixed connection of the two boxes.

[0034] Next, the fixing protrusion 16 is fixedly installed on the external frame using fastening screws, and the lamp bead substrate 19 is fixedly installed on the lamp assembly frame 18. The wire is introduced into the exposed chamber 14 through the wiring hole 17 and connected to the first lamp bead 191 and the second lamp bead 192 on the lamp bead substrate 19. When the external power is turned on, the first lamp bead 191 and the second lamp bead 192 have different colors, which can realize dual-color light emission operation.

[0035] Next, align the rectangular frame 20 on the cover plate 2 with the rectangular groove 15 on the front wall of the exposed chamber 14, and fix the rectangular frame 20 on the groove wall of the rectangular groove 15 with multiple fastening screws to complete the installation of the cover plate 2. The light can then shine outward from the corresponding first light emission hole 21 and second light emission hole 22.

[0036] Finally, if maintenance or replacement of LED chips is required, simply loosen the corresponding fastening screws to easily remove the cover plate 2 or the LED chip substrate 19 for necessary maintenance.
