3.Product features and application of pc led light diffuser.
Features: With a light transmittance reaching 85%–92%, it reduces energy consumption, enhances fixture illuminance, and promotes energy efficiency and environmental sustainability. It maintains consistent color rendering properties of the light source, minimizes chromatic deviation, and faithfully reproduces the true colors of objects. Additionally, it effectively reduces optical interference, preserves the original photometric distribution curve of the fixture, and ensures optimal lighting performance.Superior heat-stability, Superior light diffusion, UV resistant, impact resistant, heat resistant, flame retardant, low weight, ROHS compliant, both frosted and smooth finishing are available.

FAQ
Q: What is the difference between PC diffuser sheets and acrylic (PMMA) diffuser sheets? Why choose PC?
A: Polycarbonate (PC) diffuser sheets offer over 200 times greater impact resistance than acrylic, making them much less prone to cracking or breaking. They also provide superior UV resistance for long-term non-yellowing performance, with light transmittance up to 85%-92% and excellent uniformity. Additionally, PC achieves UL94 V0/V2 flame retardant ratings. Compared to acrylic, which yellows over time and is more flammable, PC is ideal for high-end LED panel lights and outdoor applications, delivering better durability, lighting quality, and lower long-term maintenance costs.
Q: What is the light transmittance and uniformity of your PC LED diffuser sheets? Can they effectively eliminate LED hot spots?
A: Our diffuser sheets achieve light transmittance of up to 85%-92%, significantly higher than standard products, effectively scattering light to eliminate hot spots and glare for exceptionally uniform, soft illumination. We offer various surface treatments (e.g., frosted, textured, opal) to maintain the original light distribution curve of your fixtures, making them perfect for demanding commercial lighting and lightbox applications.
Q: Does the product have flame retardant certification? Which high-safety scenarios is it suitable for?
A: Yes, our PC diffuser sheets are certified to UL94 V0/V2 flame retardant standards and self-extinguish in fire-far superior to flammable acrylic materials. They are highly suitable for applications with strict fire safety requirements, such as schools, hospitals, shopping malls, offices, and other LED lighting projects. They also comply with ROHS environmental standards.
Q: Will PC diffuser sheets yellow over time? How durable are they for outdoor use?
A: Made from 100% premium imported polycarbonate raw materials, our sheets offer excellent UV and weather resistance, maintaining high transmittance and color stability without yellowing even after prolonged exposure. Unlike acrylic, which yellows easily, our products are better suited for outdoor or high-intensity long-term lighting, delivering extended service life.
Q: Do you support customization of size, thickness, light transmittance, and surface patterns?
A: Absolutely! We offer full customization, including cross-sections up to 500mm wide, arbitrary length cutting, light transmittance options (70%-92%), and surface types (clear, milky white, frosted, textured, lens patterns, etc.). OEM services are available to match your specific fixture designs. Flexible minimum order quantities apply-feel free to provide drawings for sample consultation.
Q: What is the minimum order quantity (MOQ), pricing, and lead time?
A: We support small-batch customization with flexible MOQ (typically starting at 1000 meters, depending on specifications) and competitive pricing backed by our ISO9001 quality system and high-volume production capabilities. Large orders ship quickly, usually within 7-15 days. Contact us for the latest quotes and free samples for testing.
Q: Is the product lightweight? Is it easy to install and process?
A: PC material weighs only half as much as glass, making it lightweight and easy to transport. It offers high impact resistance (low breakage risk) and is simple to cut, thermoform, and install. Compared to fragile glass or processing-limited acrylic, our sheets significantly reduce installation risks and costs, ideal for various LED fixture covers and panels.
Q: How do your PC diffuser sheets help save energy?
A: With up to 92% light transmittance and superior diffusion performance, they minimize light loss and improve overall fixture illuminance, allowing lower LED power consumption for the same brightness level. Many customers report efficiency gains of over 10%, promoting energy savings and reduced electricity costs over time.
