Light Guide Acrylic Sheet distributes light evenly to the entire plane by designing microstructures (such as dots, prisms, etc.) on the surface or inside of the acrylic substrate, using the principles of light reflection, refraction and scattering. Compared with traditional light sources, light guide plates can significantly improve lighting efficiency, reduce energy consumption, and achieve lightweight design. Its manufacturing processes include screen printing, laser engraving, V-cut microstructure processing, etc., with mature technology and controllable costs.

Q: What is the difference between light guide acrylic sheet and ordinary acrylic sheet?
A: The light guide plate must have high light transmittance, low haze and specific microstructure. Ordinary acrylic sheet cannot meet the light guide requirements.
Q: How to choose the appropriate thickness of the light guide plate?
A: According to the light source type (LED/lamp tube) and size, the general thickness is 1-5mm, and the larger size needs to increase the thickness.
Q: Does the light guide plate support customized design?
A: It supports customization of microstructure, size, shape and surface treatment, and design drawings or samples are required.
Q: What is the life of the light guide plate?
A: Under normal use conditions, the life can reach 5-8 years. Weather-resistant materials should be selected for outdoor use.
Q: How to reduce the cost of the light guide plate?
A: Optimizing microstructure design, selecting domestic materials or bulk purchasing can reduce costs.
Q: Does the light guide plate meet environmental protection standards?
A: It complies with RoHS, REACH and other standards, and some products can pass UL and CE certification.
