Optimize Light Diffusion
LED display lighting and general lighting components need diffusing
solutions to distribute light evenly, avoid hot spots and reduce the number of
LEDs needed in an application. Dow Corning silicone additives, with
tailored refractive indexes close to the base resins, are appropriate choices
for LED light diffusion because they meet these requirements with virtually no
effect on mechanical or FR properties.
Dow Corning provides silicone elastomer additive powders that
deliver homogeneous dispersion across the total light spectrum to avoid color
effects. These additives are also cost-effective, thanks to their high
performance at very low loadings.
Solving Your Application
Dow Corning's silicone-based additive technology provides a range of
diffusion, transmittance and haze levels for LED lighting applications in
high-tech consumer electronic goods such as
tablets, e-readers, mobile phones and televisions, as well as backlight modules
and LED lighting plastic covers. Our additives ensure superior diffusion and
high optical performance in transparent materials, including PC, PMMA and PS,
used in LED plastic covers and backlight modules.
Dow Corning's silicone elastomer additive portfolio offers you multiple
High or medium diffusion and medium transmittance
Low to no impact on haze and a high degree of light diffusion (DLD) (at
Uniform dispersion across all wavelengths
Reduced impact on mechanical properties
Good hot spot suppression
Very low loadings of 0.5% to 0.8%
We can also develop customized solutions to help formulators, compounders
and manufacturers compete more effectively in the LED lighting market.
Product highlights include:
