Description

The Light Guide Plate (LGP) is a critical optical component designed to transform point or line light sources, such as LEDs, into a uniform, high-efficiency surface light. At Hexatron Technologies, our LGPs are manufactured using premium Mitsubishi optical-grade clear PMMA, ensuring maximum light transmission and long-term clarity without yellowing.

By utilizing state-of-the-art laser engraving technology, we produce light guides with exceptional uniformity (exceeding 85%) and the capability to cover large illuminated surfaces up to 2×4 meters. This precision allows for the creation of ultra-slim, edge-lit luminaires that maintain consistent brightness across the entire panel. Our commitment to flexibility means we offer custom cutting, machining, and fabrication with no Minimum Order Quantity (MOQ), supporting both prototyping and large-scale production.

Laser LGP: Precision and Scale Read More

The Laser LGP represents the pinnacle of backlighting technology. Unlike traditional silkscreen methods, our laser-engraved dot patterns are digitally optimized for each specific panel size. This ensures perfect light distribution even in large-format signage and architectural panels. The laser process creates permanent, high-precision micro-structures that offer superior brightness and a longer lifespan compared to printed alternatives.

Diffusive LGP: Soft and Comfortable Illumination

The Diffusive LGP is designed for applications requiring soft, visually comfortable light without visible hotspots. By integrating advanced diffusion properties directly into the light guide, this product reduces the reliance on heavy external diffusers. It is particularly effective in creating “velvet-like” light surfaces for high-end residential lighting and premium hospitality environments.

Complementary Products and Bundled Solutions

Achieving the perfect lighting effect requires a synergy between the LGP and its surrounding optical layers. Hexatron provides a complete “optical bundle” to simplify your supply chain and ensure component compatibility.

High-Performance Diffuser Sheets

The choice of a diffuser sheet is vital for controlling glare and achieving the desired aesthetic. We offer a range of materials tailored to different mechanical and fire-safety requirements:

Polystyrene (PS) & PMMA Opal Sheets: Available in 1.5–2 mm thickness, these are the industry standard for general-purpose LED panels, offering an excellent balance of light transmission and diffusion.
Fire-Rated Polycarbonate (PC) Sheets: For projects with stringent safety codes, our 1–1.5 mm PC sheets provide superior impact resistance and flame retardancy.
Ultra-Slim PC Diffuser Films: Designed for the thinnest possible profiles, these films maintain high diffusion efficiency in a fraction of the space.
Anti-Glare UGR<19 Prism Optics: For professional office environments, our 0.5 mm prism optics effectively reduce glare, ensuring compliance with international lighting standards for workplace comfort.

Integrated Reflective Films

To maximize light output, we recommend pairing our LGPs with high-reflectivity films (typically 225 µm).
