Engineered for architectural distinction. Discover our high-performance dual-lit, front-lit, and halo-effect sign solutions designed for both interior brand touchpoints and exterior facades.
In the highly competitive commercial landscape, architectural signs act as visual anchors. Custom Front and Back Lit Channel Letters represent the pinnacle of industrial illumination engineering. Also known as dual-lit or combination-lit letters, they utilize independent internal circuit structures to cast light in two directions simultaneously: outward from the acrylic front face for sharp, vibrant reading at long distances, and backward onto the wall for a soft, premium halo (corona) effect.
This dual-light projection establishes a high-contrast 3D spatial silhouette. Modern high-street luxury retailers, corporate headquarters, and upscale hospitality institutions leverage this technology to increase visual legibility under complex ambient light conditions.
Our dual-lit channel letters feature a light-isolation structural plate. This structural core prevents light bleed between front and back circuits, allowing you to run warm white halos (3000K) against deep corporate blue faces (6500K) without color contamination.
A Premier Global Architectural Signage Manufacturer & Engineering Hub
Established over two decades ago, Kexian Advertising integrates design, advanced fabrication, and global distribution. Operating from our state-of-the-art production complex in Sichuan, China, we specialize in high-end brand signs, ranging from massive LED high-rise letters to intricate hotel door signage.
By controlling 100% of our production in-house, we eliminate intermediate supply chain markups, allowing us to deliver premium European and American grade signage at factory pricing. Our team works hand-in-hand with developers, architects, and franchise expansion managers to convert complex brand identities into reliable physical structures.
How distinct geographic markets utilize dual-lit system designs to satisfy local aesthetics, zoning restrictions, and severe weather codes.
In the US and Canada, signage must satisfy stringent municipal codes (UL 48 standards, NEC compliance, and dark-sky regulations). Front and back lit systems are designed to limit sky glow while maximizing readability in heavy snow or high heat environments. Custom mounting brackets (racetracks or direct flush wall studs) are utilized for easy electrician access.
European commercial zones favor historic integration, requiring low-profile signs with clean serif fonts and softer color temperatures (2700K - 4000K). Energy conservation directives call for high luminous efficacy LED systems (minimum 120 lm/W). Our CE and RoHS compliant configurations provide the exact micro-lumens required for high street stores without light pollution.
The GCC region demands signs that survive persistent sandstorms, extreme UV exposure, and temperatures over 50°C. We design these with marine-grade 316 stainless steel housings, high UV-resistant acrylic faces that won’t yellow, and IP68 external power modules. This maintains structural and cosmetic stability over decades.
Every sign is fabricated, assembled, and certified under strict ISO 9001 guidelines, using state-of-the-art precision machinery.
High-frequency lasers slice clean metal edges and acrylic faces.
CNC automated flanging forms return walls to match clean curvatures.
Micro-seam welding bonds front returns without thermal distortion.
Applying Pantone matching, weather-proof direct UV colors.
24-hour heat run-in, waterproof verification, and electrical testing.
From raw metal to final globally certified signage—here is how we protect your capital and brand image.
We maintain a flexible low MOQ starting at 1 piece for prototype approvals, alongside high-capacity production lines for large franchise runs, saving you time and initial capital investment.
Our structure-design engineers translate complex custom layouts into load-tested signage solutions, matching all electrical systems to local market certifications.
Track progress visually with status photos and high-definition live tracking video feeds throughout each cutting, bending, and assembly step.
All wiring and internal electrical systems carry CE, RoHS, FCC, and UL certifications, ensuring building-code safety and local commercial compliance.
We regularly supply industry leaders (including Midea, Gree, JD, Liansu, and other major brands) with high-integrity signage solutions.
Through our partnerships with FedEx, DHL, UPS, and ocean freight networks, we ship securely crated signs anywhere in the world.
We utilize clean-cutting fiber lasers, CNC benders, and high-precision welding components to guarantee 0.1mm alignment tolerances.
Every illuminated sign complies with structural safety codes. We are verified by testing bodies globally.
Answers to common structural, electrical, and integration questions from project managers and engineers.
We insert an internal structural divider plate (usually 1.2mm powder-coated aluminum or galvanized steel) within the letter cavity. This divider prevents light from bleeding between the forward-facing LEDs and the backward-facing LEDs. This allows you to combine warm white halo glows with cold white face colors without optical blending.
For projects within 5 miles of ocean coastlines, we recommend utilizing marine-grade SUS316 stainless steel housings rather than SUS304. Additionally, we use clear polyurethane potting for the LED strips (IP68) and marine-grade protective powders to prevent salt-fog pitting and electrical shorting.
To create a halo glow, the letters must be offset from the wall. We weld threaded rod sleeves to the back returns of the metal. Clear acrylic standoffs (typically 15mm to 30mm long) slide over these studs to hold the letter at a consistent distance from the building face.
We use premium LED chips (primarily Epistar or Osram) rated for 50,000 hours of continuous operations, paired with Mean Well power supplies. Under normal conditions, our sign installations include a comprehensive 3-year factory warranty on the light source and a 5-year warranty on structural casings.
