The PyraLed® Makrolon DX 1139 gloss/gloss diffuser in 1.5mm thickness is an efficient diffuser with a good balance between light transmission and diffusivity. This allows the diffuser to spread the light evenly on a short distance from the light source, while keeping a lot of the emitted light. The DX 1139 is made for use with cold, white light, which corresponds to a high Kelvin value. This is because the DX 1139 barely influences the Kelvin value after applying the diffuser. It has UV protection, allowing you to safely apply the diffuser outside.
The PyraLed® Makrolon DX 1139 gloss/gloss has a two-sided gloss surface. The diffuser is 1.5mm thick and has a light transmission of 65%. 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 diffusivity, a score that refers to how well the light is scattered, is 0.82. That gives the PyraLed® Makrolon DX 1139 a distance factor of 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 PyraLed® Makrolon DX 1139 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 of increasing the light output.
The PyraLed® Makrolon DX 1139 is made from polycarbonate. This is an extrusion product. Light diffusers made from polycarbonate have a few important benefits in comparison with acrylic. Polycarbonate is very impact resistant, making it well suited for applications where the material has to be vandal-proof, burglary proof or extra safe. Because polycarbonate is an extrusion product, the thickness tolerance of the material is minimal.
Polycarbonate has a good fire classification, bs1d0 according to the European classification EN13501. Because of this high classification, the material may be used in public spaces.
Polycarbonate is not UV stable in itself. But most of the polycarbonate diffusers in our assortment are developed with a UV protective layer, allowing safe use outside. Please check if the chosen diffuser has UV protection when you plan to use the diffuser outside.
The PyraLed® Makrolon DX 1139 in 1.5mm thickness is in stock in sheet size 2050mm x 1250mm. If you need a smaller size for your application, we gladly offer material cut to size.
The PyraLed® Makrolon DX 1139 gloss/gloss is also available in the same sheetsize in 3mm thickness.
The PyraLed® Makrolon DX 1139 1.5mm is an efficient and well balanced diffuser. It combines a high level of light transmission with good diffusivity. The DX 1139 is developed for use with cold, white light. This is light with a high Kelvin value. This is because the use of the DX 1139 barely influences the measured Kelvin value. And with the minimum amount of thickness tolerance and the impact resistance of polycarbonate, this diffuser can be applied in many circumstances. You can use the PyraLed® Makrolon DX 1139 UV 1.5mm for light fixtures, profiles, signing and displays. Barfronts, signing and other esthetic applications are also possible.
Due to the good fire classification of polycarbonate, this diffuser may be used in public spaces. And the DX 1139 has UV protection, allowing you to use the diffuser inside and outside without risk.
PyraSied also offers the PyraLed® Makrolon DX 1141 gloss/gloss 1.5mm. Just like the DX 1139, this diffuser combines a good diffusivity with a high level of light transmission. The main difference is the optimalisation for warm, yellow to red light of the DX 1141. This is light with a low Kelvin value. Applying the DX 1141 lowers the measured Kelvin value.
For constructive applications like floors, walls and full bars and desks, we recommend a thicker diffuser, like our PyraLed®3 10mm or the PyraLed® OPY3 satin/satin 10mm. These diffusers are made from cast acrylic. Diffusers with these thicknesses are not available in polycarbonate.
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.
The PyraLed® Makrolon DX 1139 gloss/gloss 1.5mm is made from polycarbonate. Diffusers from polycarbonate can be fabricated easily.
PyraSied has more than 30 years of experience in fabricating polycarbonate 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 polycarbonate yourself, often with the same tools used for wood fabricating. Fabrication options for the PyraLed® Makrolon DX 1139 diffuser are sawing, milling, bonding, drilling, faceting, polishing, sanding and printing.
