Product Description

SUNSIGN Custom LED Channel Letters with trimless and front-lit design provide a functional and adaptable signage solution for both indoor and outdoor applications. Each letter is constructed with an acrylic front panel that allows LED light to pass through efficiently and metal returns and sides that provide structural support. The trimless design removes the traditional trim cap, creating a flat, continuous edge suitable for direct mounting to walls, back brackets, or freestanding bases. This design also allows letters to align seamlessly when forming words or logos.

The acrylic face is available in different thicknesses depending on letter size and illumination requirements, and it transmits LED light evenly. Letters can incorporate LED strips or LED modules mounted inside the hollow returns. The metal returns, fabricated from aluminum or stainless steel, provide rigidity and structural stability. Brass or other metals can be included for specific structural or aesthetic requirements. Each letter is hollow inside to accommodate LED modules, wiring, and connectors, allowing access for maintenance and heat dissipation.

LED modules operate on DC 12V and are compatible with DC drivers, AC transformers, plugs, or adapters. This flexibility supports various installation setups and power requirements. The LEDs are rated for 50,000 hours of operation, reducing replacement needs. The combination of metal returns and acrylic faces allows for straightforward cleaning and routine maintenance. IP65-rated enclosures protect letters from water and dust, ensuring suitability for outdoor conditions.

Key Features and Construction Details

• Face Material: Acrylic sheets of varying thickness transmit LED light. Edges can be straight or beveled according to design.

• Returns / Sides: Aluminum or stainless steel provides structural support. Thickness can be adjusted according to letter dimensions.

• Back Panel: Optional stainless steel or aluminum panels provide mounting support and secure LED modules.

• Light Source: LED strips or modules mounted inside the letter returns provide uniform illumination. Modules can be arranged for full-face or edge lighting depending on design.

• Finish Options: UV printing, brushed metal, polished metal, or painted finishes.

• Waterproofing: IP65-rated enclosures prevent water ingress, suitable for outdoor use.

• Power Supply: DC drivers, AC transformers, plugs, or adapters supply power. Wiring channels are integrated into the letter structure for clean and concealed connections.

Applications

• Storefronts: Display business names, logos, and brand identity.

• Restaurants & Bars: Interior or exterior signage for logos and text.

• Hotels & Offices: Lobby signage, directories, or brand logos.

• Retail Stores & Pharmacies: Wall-mounted or freestanding letter displays.

• Exhibition Booths & Trade Shows: Modular signage for temporary or movable installations.

Installation Notes

Letters can be mounted individually or in sequences to form words or phrases. Wall mounting can utilize pre-drilled holes, stud systems, or adhesive methods depending on surface type. Back brackets provide spacing for halo or backlit effects. Freestanding letters use base plates or brackets for stability. Internal wiring channels allow connection to power supplies without visible cabling, maintaining a clean and professional appearance. Proper alignment and level installation ensure uniform lighting and visual consistency.

Maintenance and Performance

LEDs are low-power and designed for long-term operation, with a rated lifetime of 50,000 hours. Metal returns and acrylic faces can be cleaned with standard solutions without affecting performance. Waterproof construction ensures suitability for outdoor use. UV-stable finishes prevent fading over time. Letters can be serviced by removing the back panel or accessing LEDs through the returns. Routine inspection of electrical connections and mounting hardware helps maintain consistent illumination and structural integrity. The modular design allows for easy replacement of individual LEDs or modules if needed.
