Diffuser Sheet UGR<19

Against the backdrop of increasingly strict indoor lighting visual comfort regulations across all European Union member states, Diffuser Sheet UGR<19 has evolved from an optional optical accessory into a mandatory core component for nearly all commercial, educational, medical and public architectural lighting projects. Our company is a professional vertical integrated optical plastic factory specializing in the R&D, extrusion, deep processing and customized production of Diffuser Sheet UGR<19, serving hundreds of European custom lighting manufacturers.

Unlike generic frosted diffuser sheets or low-precision prismatic panels circulated by trading companies, our independently developed Diffuser Sheet UGR<19 adopts micron-level precision micro-prism microstructure molding technology, which can effectively intercept high-angle stray light above 65°, strictly control the unified glare rating below 19, and maintain ultra-high light transmittance above 88% at the same time. This dual advantage of low glare and high luminous efficiency perfectly matches the core lighting standard EN 12464-1 issued by the European Committee for Standardization.

For European clients focusing on customized luminaire development and large-scale construction project bidding, the biggest challenge in sourcing Diffuser Sheet UGR<19 is balancing stable optical performance, full EU regulatory compliance, flexible personalized customization and reliable mass delivery capacity. As a direct manufacturer with 12 years of optical plastic extrusion experience, we eliminate all intermediate trading links, provide one-stop OEM/ODM customization services for Diffuser Sheet UGR<19 from raw material formulation adjustment.

Diffuser Sheet UGR<19 is a professional micro-prismatic optical diffusion plate specially engineered to limit the Unified Glare Rating (UGR) value of indoor LED luminaires to less than 19 after assembly. UGR is a unified international evaluation standard for visual discomfort glare formulated by CIE (International Commission on Illumination). European EN 12464-1 clearly stipulates that all workspaces with long-term computer operation, reading and writing activities must use lighting fixtures with UGR ≤19; open offices, classrooms.

Traditional milky white frosted diffusers rely on light absorption to weaken glare, which will cause 25%-40% luminous flux loss and increase the overall power consumption of the luminaire, conflicting with the EU Ecodesign Directive's energy-saving requirements. Conventional low-precision prismatic sheets on the market often fail to stabilize UGR below 19 after matching different LED light sources and lamp housing structures, resulting in project acceptance failure and huge economic losses for European contractors.
