When working with PMMA diffuser sheets it’s important to remember that plastics don’t stay the same size under all conditions. They expand in heat and contract in cold. This natural behavior, known as thermal expansion, can affect the final dimensions and fit of your sheets in lighting, display, or architectural applications. To make planning easier, […]
A Light Guide Plate (LGP) is a thin, transparent optical sheet typically made from optical-grade acrylic (PMMA) or polycarbonate (PC). It is designed to distribute light evenly across its surface by guiding light from edge-mounted LEDs and emitting it uniformly through the front face. Originally developed for LCD backlight modules (BLUs), the LGP has evolved into a core optical component in LED panel lighting, architectural illumination, and decorative display systems. The unique value of an […]
Our diffuser film is often used in conjunction with clear micro prismatic sheets in LED luminaires to help achieve a UGR (Unified Glare Rating) of less than 19, which is the recommended limit for indoor lighting. Our micro prismatic sheet is designed to control light by redirecting and diffusing it, which can help to reduce […]
A light guide plate (LGP) is a transparent acrylic or polycarbonate sheet used to evenly distribute light from a light source to a surface or object. LGPs work by using total internal reflection to guide light from the edge of the plate to its surface, where it is evenly distributed through a series of laser […]
Here are some aspects that can contribute to the aesthetics and beauty of a black diffuser for LED lighting: Sleekness: Black is often associated with sophistication and sleekness, so a black diffuser can enhance the overall aesthetic of a space by adding a modern and stylish touch. Contrast: The contrast between the black diffuser and […]
Achieving reduced glare in linear lighting is a difficult task. Most of the UGR<19 compliant luminaires are panels made out of prismatic sheets like the Plexi Honeycomb + the Opto90 PET225. Currently we are manufacturing profile lenses with prismatic pattern that could use our optical films like the Opto90 PET225 as a complement to achieve […]
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 […]
