Are you looking for a reliable light guide plate/panel manufacturer? THBright provides high-quality light guide panels in various thicknesses, shapes, and sizes, ready to meet your bespoke requirements. We offer no MOQ and fast sample delivery within 2 working days.
What is a Light Guide Panel? (Definition)
A light guide panel (LGP), also known as a light guide plate in optical engineering, is a precision optical component designed to distribute LED light evenly across a surface. It remains transparent when no light is applied but emits a uniform, bright light across its entire surface when connected to a light source.
Premium Raw Materials (Material)
The performance of an LGP depends heavily on the light guide plate material. At THBright, we offer a range of options to suit different project budgets and quality requirements:
- PMMA Light Guide Plate: We primarily use optical-grade cast PMMA, sourced from trusted manufacturers such as Mitsubishi, Donchamp, and HASWEIT. These acrylic light guide plates are known for their exceptional light transmission (up to 93%) and resistance to yellowing over time.
- PS Light Guide Plate: For cost-sensitive projects, we also provide polystyrene (PS) options without compromising light uniformity.
Precision Manufacturing (Machinery)
To ensure perfect edge finishing and maximum light coupling efficiency, we use high-quality light guide plate cutting machines and advanced processing equipment. Every panel is produced with smooth, polished edges to maximize light entry and minimize loss, regardless of its shape or size. Our thickness tolerance is ±1mm, ensuring consistent quality.
Thickness and Specifications (Size)
We offer standard and custom thicknesses ranging from 2mm to 20mm or more, allowing flexible solutions for different projects. Our most popular specifications are:
These thicknesses provide the perfect balance between structural rigidity and slim aesthetics, ideal for architectural and commercial lighting applications.
Superior Uniformity (Learn More)
Achieving even lighting is our specialty. Our unique dotting algorithms ensure light is distributed evenly across the panel, eliminating dark spots. THBright LGPs typically achieve up to 90% uniformity, measured with a 9-point test. For clients seeking >90% uniformity, we apply our advanced light guide panel technology, which often surprises customers when they receive their samples.
Applications (Usage)
Our LGPs are the backbone of modern LED lighting solutions. Common applications include:
- Slim LED light panels for offices and retail
- Advertising LED light boxes and signage
- Architectural LED light panels for backlighting
