Description

Our Light Guide Plate (LGP) is made from Mitsubishi optical-grade clear PMMA, the best material to reach the highest uniformity and luminaire efficiency. The state-of-the-art laser engraving machines allow us to make light guides with the largest illuminated surface, up to 2×4 meters. That’s a unique competitive advantage. The LGP thickness could be any from 2mm up to 15mm. Our inventory of clear sheets allows us the flexibility to serve customers with any special request without MOQ. Learn more about LGP.

We can supply the complete optical plastic parts for manufacturers:

• The back reflective sheet.
• The LGP itself, and the front diffuser sheet, is in matte opal or clear prismatic surface for UGR<19 luminaires.

LGP Types

Our Light Guide Plate family includes specialized solutions for different design and performance requirements:

• Laser LGP – Precision laser-engraved dot patterns for high uniformity and large panels
• Thin LGP – Optimized for ultra-slim luminaires and space-constrained designs
• Diffusive LGP – Enhanced diffusion for soft, visually comfortable illumination

Complement Products

Lighting manufacturers often purchase Light Guide Plates (LGPs) as part of a complete lighting bundle, including:

Diffuser sheet options:

• Polystyrene (PS) or PMMA opal sheets of 1.5–2 mm thickness, or
• Fire-rated Polycarbonate (PC) sheets of 1–1.5 mm, or
• PC diffuser films for ultra-slim designs, or anti-glare UGR<19 prism optics in 0.5 mm thickness.

Light Guide Plates: Most commonly used thicknesses are 3 mm and 4 mm, delivering uniform light distribution.

Reflective Films: Available in various thicknesses, with 225 µm being the most popular. As an optional service, we can bond the reflective film to the LGP at no additional cost, simplifying assembly.

Most common applications:

• Slim LED panel lights and architectural linear fixtures.
• Signage and light boxes.
• Displays.
• Emergency lighting.
• Automotive lighting.
• Point of purchase display.
