Our PyraLed® OPY2 and OPY3 light diffusers have the best light technical properties within our collection of diffusers of cast acrylic. The PyraLed® OPY3 gloss/gloss 5mm is developed to offer the best possible diffusivity while still keeping a high light transmission.
The PyraLed® OPY3 5mm has a two-sided gloss surface, is 5mm thick and with a diffusivity of 0.85 it spreads the light well on a short distance from the light source. Diffusivity is a score that refers to how well the diffuser scatters the light. Because of the high diffusivity, the distance factor is just 1.2. This means that the distance between the diffuser and the leds needs to be 1.2 times larger than the distance between the led strips or led button cells themselves to get a nice and diffuse light result. The light transmission of the PyraLed® OPY3 5mm is 49%. The light transmission refers to the amount of light that comes through the diffuser. It is measured on the other side of the light diffuser than where the light source is positioned.
The PyraLed® OPY3 diffuser is part of our collection with advanced diffusers. These diffusers are developed with the goal of reaching the highest possible quality. This can be seen on how they score on the variable ‘efficiency’. This is measured by multiplying the light transmission with the diffusivity. The light transmission is a measurement of the amount of light transmitted. The diffusivity refers to to how well a diffuser scatters the light. A diffuser that has a higher score on the variable ‘efficiency’ performs better. An efficient diffuser is more expensive to purchase, but earns itself back by saving energy or increasing the light output.
The PyraLed® OPY3 is made from cast acrylic. Light diffusers from cast acrylic have the best light technical properties and are optically clear, UV-stable and colourfast. Because of this, the diffusers can be used inside and outside and the colour will not be influenced by the sun. The fire classification of cast acrylic is E according to fire norm EN 13501. This is the European (EU) classification.
Cast acrylic can be produced in smaller batches relatively easy. This allows us to offer the broadest collection of thicknesses and types in cast acrylic.
The PyraLed® OPY3 with two-sided gloss surface in 5mm thickness is in stock in sheet size 3050mm x 2030mm. If you need a smaller size for your application, we gladly offer material cut to size.
The PyraLed® OPY3 gloss/gloss is also available in the same sheetsize in 10mm thickness.
If you look for a diffuser with the highest possible diffusivity and want to place the sheet close to the light source, the PyraLed® OPY3 is the right choice. And since cast acrylic has the best light technical properties of all light diffusers, you can apply the PyraLed® OPY3 in many situations. You can apply the 5mm thick version of the PyraLed® OPY3 with two-sided gloss surface for barfronts, signage, decors, displays and other esthetic applications. Because cast acrylic is UV stable and the colour is not affected by sunlight, you can safely apply it inside and outside.
For constructive applications like floors, walls and full bars and desks, a thicker version of the PyraLed® OPY3 is more suitable, like the 10mm gloss/gloss.
Are you looking for a diffuser that offers maximum light transmission? Then the PyraLed® OPY2 satin/satin 5mm is the better option. This is the best performing diffuser made from cast acrylic on the light transmission variable. The result is a diffuser that keeps most of the light result emitted from the leds.
Cast acrylic has thickness tolerance, making it less suitable for the use in light fixtures and profiles. Extruded acrylic (XT) has minimum thickness tolerance, making it a perfect match for these applications. The PyraLed® YT275 matte/gloss is an excellent alternative in XT, offering a light transmission of 81%.
Looking for inspiration? Please check our Acrylic community. You can find many applications with light diffusers. There are also many other applications with acrylic on the platform.
Diffusers made from cast acrylic contain less tension than diffusers from extruded acrylic. The PyraLed® OPY3 is made from cast acrylic and can be fabricated easily.
PyraSied has more than 30 years of experience in fabricating acrylic and other plastics. With our excellently equipped workshop – where high-tech machinery and traditional craftsmanship ensure high quality – we can supply diffusers made to size. Whether you are looking for a partner for a one-time project or a trustworthy partner for the continious supply of diffusers as part of your supply chain, PyraSied is the right choice.
You can fabricate acrylic yourself, often with the same tools used for wood fabricating. Fabrication options for the PyraLed® OPY3 diffuser are lasering, sawing, milling, bonding, drilling, faceting, polishing, sanding and printing.
