Laser LGP
The Laser Light Guide Plate (Laser LGP) is a precision-engineered optical component designed to deliver uniform high-efficiency illumination in LED lighting systems. Using laser-engraved dot patterns, our Laser LGP provides exceptional control of light extraction across the surface, resulting in superior brightness uniformity, minimal hot spots, and excellent visual comfort.
Manufactured from optical-grade PMMA (acrylic) with advanced laser processing technology, the Laser LGP is ideal for applications requiring large-area light distribution, high lumen output, and ultra-thin form factors.

- Customizable Optical Profiles: Tailored for each project’s lumen distribution, size, and thickness targets.
Integration Guidelines
LED Placement
- Edge-lighting configurations are optimized via simulation to ensure uniform light spread.
- LED strips/arrays can be positioned along one or multiple edges depending on size.
Diffuser Pairing
Laser LGPs are typically paired with front diffuser sheets (opal, prism, or UGR-optimized) to:
- Soften luminance transitions
- Achieve visual comfort requirements
- Control glare (UGR < 19 for office applications)
Reflector Optimization
Back reflective sheets improve output by redirecting backward-emitted light toward the front surface, enhancing overall system efficacy.
