Project Background: Reshaping Brand Touchpoints with High-Tech Light Boxes
Against the backdrop of accelerating mobile payment adoption and increasingly diverse payment methods, China UnionPay continues to advance its brand image upgrade and payment scenario innovation. Elevator corridors, as high-frequency touchpoints in office buildings, shopping malls, and high-end communities, are important offline positions for brand-user communication. Recently, China UnionPay deployed a batch of new dynamic light boxes on elevator corridor ceilings, replacing traditional static advertising visuals with dynamic lighting effects and further strengthening UnionPay’s brand image of being “international, vibrant, and fashionable.”
The light source solution for this light box project uses SN-P30RGB+W dynamic LED light panels provided by SANNAN. Headquartered in Shenzhen, China, SANNAN specializes in designing and manufacturing dynamic LED lighting solutions for retail, commercial, exhibition, and architectural applications. Its products have been widely used in retail stores, shopping malls, exhibition booths, automobile showrooms, airports, and commercial buildings. This UnionPay elevator light box project is a typical implementation of the product in the financial brand display sector.
Technical Solution: Core Capabilities of the SN-P30RGB+W Light Panel
The SN-P30RGB+W is the premium model in SANNAN RGB dynamic light box series. The series includes three specifications—P20-RGB, P30-RGB, and P30-RGB+W—forming a complete product matrix: P20-RGB is suitable for narrow-bezel, high-precision small display walls; P30-RGB, as the classic flagship model, is ideal for large-format backdrop walls and custom exhibition builds; and P30-RGB+W adds an independent white light channel to RGB, making it the core choice for this project.
The most prominent technical feature of the SN-P30RGB+W is its RGB+W dual-channel architecture. Traditional RGB light panels can only achieve color mixing from red, green, and blue, which limits color fidelity in scenarios where realistic materials need to be displayed. By adding an independent white light channel, the SN-P30RGB+W retains cool neon gradient effects while also delivering soft, warm natural-light effects, significantly improving the color reproduction accuracy of physical posters such as apparel and food.
In actual display, the same printed poster, relying on the dynamic backlighting of the light box, can easily switch between three atmosphere themes—”Aurora Glow,” “Sunset Warm Orange,” and “Starlight Diffusion.” The same image can unlock completely different visual tones, greatly expanding the creative space for brands. This feature is especially practical for UnionPay elevator light boxes displaying diverse content such as key brand visuals, campaign posters, and product images.
The light box as a whole adopts a ceiling-recessed installation structure, is 12 cm thick, and supports color temperature adjustment via remote control, adapting to the installation requirements of elevator corridor ceiling spaces. SANNAN strictly tests every lighting solution before it leaves the factory to ensure stability, safety, and long-term performance.
Application Value: From Static Display to Dynamic Brand Experience
Traditional elevator light boxes generally have two major pain points: first, their visual effect is monotonous, and static images struggle to capture elevator passengers’ attention in a short time; second, using ordinary LED screens as an alternative involves higher investment costs and a poor close-up viewing experience. The SN-P30RGB+W dynamic light box solution strikes a balance between the two—achieving dynamic light-and-shadow effects at a cost close to that of traditional light boxes while maintaining comfortable close-up viewing.
At the Shanghai International Advertising, Signage and Printing Exhibition in March 2026, SANNAN’s three side-by-side demo light boxes became a popular photo spot in the exhibition area thanks to their continuously changing light and shadow effects. Industry professionals from UV printing factories, exhibition construction companies, and chain brand owners all spoke highly of the solution, believing it effectively solved the visual monotony of traditional static light boxes. This feedback from the industry also confirms the maturity and scalability of the technical solution in commercial display scenarios.
For China UnionPay, elevator corridor light boxes are not only advertising carriers but also touchpoints for building an emotional connection between the brand and users. In recent years, UnionPay has continued to convey trust and warmth through brand IPs such as the “Baifu” series, and its “Project Splendor” has also been continuously optimizing payment experiences at home and abroad. The deployment of elevator dynamic light boxes extends this brand care into the physical spaces users pass through daily. When elevator passengers look up and see UnionPay brand visuals with flowing light and shadow, the visual experience—combining a sense of technology and approachability—is silently reinforcing the perception of UnionPay as a “trusted global payment brand.”
Supplier Perspective: Empowering Brand Spaces with Dynamic Lighting Solutions
As the dynamic LED light panel supplier for this project, SANNAN upholds the brand vision of “LIGHT IN MOTION,” committed to making lighting not only illuminate spaces but also create emotion and enhance environmental experience. The company’s team works closely with architects, designers, retailers, advertising agencies, and lighting solution providers, offering full-chain support from intelligent lighting systems to custom engineering.
In the UnionPay elevator light box project, the application of the SN-P30RGB+W light panel validates the feasibility and expressive power of dynamic LED lighting technology in offline scenarios for financial brands. In the future, as commercial spaces place ever higher demands on brand display effects, dynamic light box solutions that balance visual impact and cost controllability are expected to be applied in more brand scenarios.
