1.What is an Acrylic Light Guide Plate?

Definition of Acrylic Light Guide Plate

To understand what an acrylic light guide plate is, one must first grasp the nature of acrylic sheets. Acrylic sheets, known as Acrylics in English, are polymerized from methyl methacrylate monomer (MMA), resulting in polymethyl methacrylate (PMMA) sheets—commonly called plexiglass.

An acrylic light guide plate, also known as a light-transmitting plate, uses optical-grade acrylic sheet as its material. Employing backlight module technology, it leverages the high light transmission efficiency of light guide points. Through computer-calculated placement of these points, the plate refracts light into a uniform, diffuse illumination state during manufacturing.

Acrylic LED light guide plates leverage acrylic’s light transmission properties by incorporating light-guiding points within the acrylic to uniformly diffuse light, achieving the desired lighting effect.

2. Characteristics of Acrylic Light Guide Panels

a. Uniform Light Distribution

Typically manufactured in controlled environments with constant temperature, humidity, and dust-free conditions, these panels offer high light transmission, excellent transparency, ultra-thin profiles, and exceptional brightness. They eliminate dark zones, achieving uniform light distribution with consistency rates reaching 90% or higher.

b. High Formability

Exceptional moldability and superior processability accommodate diverse creative designs. They are easily customizable, offering tailored services for textures, colors, specifications, structures, and shapes. They can be cut to any required size or assembled for use, featuring simple craftsmanship and convenient production.

c. Superior Performance

Low density, lightweight, high impact resistance, excellent weather resistance, and high safety. Compatible with any light source, including LED, CCFL (cold cathode fluorescent lamps), and fluorescent tubes. High light conversion efficiency, extended lifespan, safe and eco-friendly, suitable for both indoor and outdoor applications.

d. Cost-Effective

Delivers high luminous efficiency with low power consumption for equivalent area illumination. Thinner products can achieve the same brightness, reducing material costs.

3. Applications of Acrylic Light Guide Plates

Common applications include:

• LED Backlight Panels – used in TVs, monitors, and advertising displays
• Interior and Decorative Lighting – ceiling lights, wall panels, signage
• Office and Commercial Lighting – uniform illumination for workspaces
• Portable and Specialty Lighting – lightboxes, instruments, and display cases
