Description

Technical Field

[0001] This utility model relates to the field of advertising sign technology, specifically to a lightbox-type polycarbonate panel background wall. Background Technology

[0002] With the rapid development of society and the iterative upgrading of indoor advertising carriers, the limitations of traditional lightbox background wall materials in terms of light transmission, weather resistance, energy saving, safety, and shelf life have become increasingly prominent. As a new type of high-polymer composite material, lightbox-style polycarbonate background wall has become the preferred solution for modern urban commercial space signage systems due to its technical advantages such as high light transmittance, impact resistance, and double-layer hollow heat insulation structure.

[0003] However, existing lightbox-style polycarbonate panel background walls use side lighting around the lightbox, resulting in noticeable shadows and dark spots in the center. In contrast, LED front lighting, with its high light transmittance, makes the LED beads inside the lightbox easily visible. Furthermore, to enhance the atmosphere, UV-printed images are typically applied to the polycarbonate panel, exposing the printed surface directly to the external environment. This makes it susceptible to scratches, wear, UV radiation, and chemical corrosion, increasing the frequency of additional protection or replacement and raising usage costs. Utility Model Content

[0004] The technical problem this utility model aims to solve is that traditional lightbox background walls suffer from monotonous visual effects, easy aging, poor impact resistance, and difficulties in transportation, installation, and maintenance.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is to provide a lightbox-type polycarbonate panel background wall, including a wall surface and a lightbox. The back of the lightbox is provided with a light panel, which is detachably connected to the wall surface. The front of the lightbox is provided with a light cloth, on which a polycarbonate panel is installed. The lightbox is a rectangular frame composed of multiple aluminum profiles spliced ​​together. Two adjacent aluminum profiles at the corners of the rectangular frame are fixedly connected by right-angle connecting brackets. One end of each aluminum profile has a right-angled bottom plane, and the other end has a snap-fit. The light panel is connected to the right-angled bottom plane of the aluminum profile. The edge of the light cloth is located within the snap-fit ​​of the aluminum profile. The top, bottom, and one side of the lightbox are provided with a pressing frame, and the other side is provided with a edging plate. An LED light is provided on the side of the light panel located inside the lightbox.

[0006] Optionally, the aluminum profile has slots at both ends, pan head screws are provided in the slots, and fixing holes are provided in the connecting angle brackets. The connecting angle brackets are inserted into the aluminum profiles and fixed by the pan head screws passing through the fixing holes.

[0007] Optionally, the outer end of the right angle of the connecting bracket is rounded, and the inner angle is provided with a rounded groove.

[0008] Optionally, the aluminum profile has serrations in the slot, and the lamp cloth has a soft rubber strip around its perimeter with a wavy pattern. The soft rubber strip is inserted into the slot, and the wavy pattern on the soft rubber strip is connected to the serrations.

[0009] Optionally, the wall surface is provided with a wooden board, and the side of the light panel opposite to the wall surface and the wooden board on the wall surface are provided with wooden 45° hanging corners fixed with screws. The wooden 45° hanging corners on the light panel are located above the wooden 45° hanging corners on the wall surface, and the two are connected to each other.

[0010] Optionally, an anti-detachment component is provided at the upper rear end of the light box. The anti-detachment component is right-angled, with one side connected to a wooden board on the wall by screws and the other side connected to the top of the light box. A decorative strip is provided at the front end of the upper row of light boxes.

[0011] Optionally, the aluminum profile has a white coating on one side inside the light box.

[0012] Optionally, at least two light boxes are provided, which are placed side by side horizontally. A pressing frame is provided on the adjacent side between the two light boxes, and a edging board is provided on the opposite side.

[0013] In summary, this utility model has at least one of the following beneficial effects:

[0014] 1. This utility model uses aluminum profiles for the outer frame, making product manufacturing more convenient, saving time, labor, costs, and production cycle. The aluminum profile connecting grooves facilitate easy product splicing. The sawtooth design of the bayonet grooves ensures a tighter and more stable connection between two components, preventing loosening or detachment. The white coating inside the light box improves light focusing, effectively reducing the number of LED lights required, saving costs and reducing energy consumption for subsequent customer use, resulting in high economic benefits. The product uses multiple components for easy transportation and labor-saving installation, reducing the waste of idle time caused by multiple workers.

[0015] 2. This utility model uses a combination of light cloth and polycarbonate sheet to solve the surface luminescence effect, creating a soft and comfortable visual environment and avoiding visual fatigue caused by strong light stimulation. By increasing the structure of the light cloth, the defects of the direct light emission of LEDs are effectively solved, which are relatively high and can make the internal LED beads visible. At the same time, it solves the problem of the product's required visual effect being relatively soft, with a hazy beauty, creating a warm and pleasant atmosphere.

[0016] 3. This utility model uses connecting corner brackets to fix the products more firmly and with better quality. The connecting corner brackets have an outer arc design at the right angle and an arc groove design at the inner corner, which reserves assembly space, solves the interference caused by dimensional accuracy errors during assembly, and improves production efficiency.

[0017] 4. This utility model uses anti-detachment components to increase product safety, and adds a decorative strip to the front end, which not only enhances the product's aesthetics but also solves the problem of installation precision and improves installation efficiency. The stainless steel frame has smooth lines, highlighting the product's simple and stylish design, increasing the visual sense of space, making the space appear more transparent, and creating unique light and shadow effects, increasing the sense of layering and three-dimensionality of the space.

[0018] 5. This utility model uses UV printing on the inner surface of the polycarbonate sheet, which makes it less susceptible to direct influence from external factors, better maintaining the integrity of the pattern and luminous effect, and potentially extending its service life. Polycarbonate sheets are superior to acrylic and glass in terms of aging resistance, impact resistance, and flexibility. The use of polycarbonate sheets solves problems such as easy aging of light boxes, high energy consumption, safety, and product shelf life. Polycarbonate sheet material is energy-saving, environmentally friendly, lightweight, beautiful, and durable, and can be used in various indoor and outdoor decorations. The product is produced in multiple small light boxes, which can form a standard, making it convenient for transportation, installation, maintenance, and lower costs. Attached Figure Description
