One-sentence Definition
An edge-lit acrylic sign is an illuminated display made from a clear acrylic panel, where LED lights are installed along the edges to create a glowing effect that highlights engraved or etched designs.
Detailed Explanation
Edge-lit acrylic signs utilize the principle of total internal reflection. LEDs are positioned along one or more edges of a high-clarity acrylic sheet. The acrylic acts as a light guide, transmitting the light internally. When the panel is engraved or etched with a design, the light scatters at those points, making the artwork or text appear to glow. This technique results in a sleek, modern look that is both energy-efficient and visually striking. Compared to backlit signs, edge-lit signs offer a thinner profile and a more subtle, refined illumination (source, source).
Key Components
Acrylic Panel: High-quality cast acrylic is preferred for its superior light transmission and durability (Curbell Plastics).
LED Modules: Energy-efficient LEDs are installed along the edges, available in various colors (including RGB for dynamic effects).
Engraving/Etching: Designs are laser-engraved or CNC-etched into the acrylic, guiding the light to create the illuminated effect.
Frame or Mount: Aluminum or powder-coated frames provide stability and a polished finish.
Power Supply & Controls: Modern edge-lit signs may include dimmers, color controls, or smart features for added flexibility.
Real-world Applications
Edge-lit acrylic signs are widely used in:
Retail Displays: Eye-catching product advertisements and brand logos.
Office Signage: Directories, conference room signs, and lobby branding.
Hospitality: Menu boards, hotel welcome signs, and event signage.
Home Decor: Personalized nameplates, wall art, and gaming setups.
Exhibitions: Portable, lightweight illuminated displays for trade shows.
For example, Curbell Plastics provided a high-end office building with outdoor edge-lit signage using 1-inch thick cast acrylic, achieving both durability and superior light transmission (case study).

Backlit Sign: Uses LEDs behind the sign face for a brighter, halo effect.
Halo-lit Sign: Illuminates the edges of raised letters for a premium look.
LED Neon Sign: Mimics traditional neon with flexible, energy-efficient LEDs.
Lightbox: Illuminated from behind, often with a translucent graphic panel.
Laser Engraving: The process used to etch designs into the acrylic.
