Using Prismatic Sheets and Films for UGR<19
Most of the premium UGR<19 compliant LED panels have an opal light effect. That is achieved by combining a translucent or semi opal film with a solid prismatic sheet.
While the clear prismatic sheet will control the beam angle to reduce the glare, the film will hide the LED hotspots. The overall effect is a smooth and uniform light output.
We supply both components. The pairing could be by mechanical means or in few cases the films are bonded to the prismatic sheet. In the case of LED panels with Light Guide Plates (LGP), the film is not bonded to the prismatic sheet because the plastic components like the reflective film, the LGP, opto film and the prismatic sheet are tight enough by the frame and the assembly method of such panels.
