Explore our engineering-grade custom exterior and interior backlit solutions.
Engineered reliability built on over two decades of scale manufacturing.
Operating from the industrial manufacturing core of Sichuan, China, Sichuan Kexian Advertising Limited Company has developed over a 20+ year trajectory into a global tier-one architectural signage supplier. We provide business partners with a complete, fully integrated manufacturing sequence—spanning conceptual design, industrial drafting, CNC component cutting, electrical assembly, quality compliance verification, and international door-to-door shipping.
Whether executing custom prototyping or scaling high-volume contract orders, Kexian coordinates each step in-house to protect quality timelines and maintain cost-efficiency. Our design division integrates structural load requirements and light emission optics to fabricate signs that are structurally durable and photometrically balanced.

Custom halo-lit (also known as reverse-lit) letters achieve their signature glow by directing light backwards against a mounting surface, producing a soft silhouette. To achieve high contrast without hot-spots, Kexian uses optical-grade PMMA light diffusion panels paired with high-performance marine-grade 304 or 316 stainless steel housings. The steel undergoes automated fiber-laser cutting and multi-axis bending to form a light cavity that eliminates light leakage.
Operating out of Sichuan allows Kexian to combine robust regional raw-material access (acrylic polymers and specialty alloys) with highly advanced industrial automation. By combining automated CNC mini-letter milling with high-frequency laser welding, our manufacturing lines operate at higher precision and lower unit costs than Western custom workshops, passing those cost savings directly to commercial clients without compromising quality.
For external architectural signage, heat dissipation is critical to preventing LED lumen degradation. Our signs are engineered with aluminum core PCBs and ventilation pathways that lower interior junction temperatures by up to 15°C. Combined with IP67 waterproof LED modules and UL/CE-certified Mean Well constant-voltage drivers, our systems run reliably in extreme weather, from sub-zero northern winters to hot tropical storefronts.

Expert answers addressing the technical aspects of custom halo-lit signage procurement.
For coastal applications with high salinity, we recommend 316-grade stainless steel over standard 304. Grade 316 contains molybdenum, which offers significantly higher resistance to pitting and crevice corrosion in chloride environments. All exterior-grade units are sealed with IP67 waterproofing to protect against moisture intrusion.
Hot-spotting (uneven light dots) is minimized by maintaining a critical distance between the LED diodes and the acrylic diffusion face, combined with high-grade optical diffusion polymers. We construct custom interior light chambers with high-density LED arrays (using 120 LEDs per meter) to ensure clean, uniform light distribution across the mounting surface.
We design and wire all signage to meet the regulatory requirements of the destination country. For North America, we supply UL-compliant components; for Europe, we build to CE and RoHS standards. Our standard configurations operate on 12V or 24V DC step-down systems powered by universal 110V-240V AC power drivers.
To produce a clean halo effect, backlit letters are typically mounted using threaded standoff pins. The offset distance typically ranges between 1.0" (25mm) and 2.0" (50mm). A smaller offset creates a sharper, more defined outline, while a larger offset produces a wider, softer glow.
We build our signs with high-efficiency SMD chips rated for 50,000 hours of active illumination. Operating the LEDs at 80% of their maximum capacity prevents overheating, helping to extend the lifespan of the lighting elements and power units.
