High performance Al mirror product L95

SMMT’s high performance Al mirror product L95 is specially designed to perform stable in CoB-LED high temperature and environmental conditions.

The extreme high reflectance is achieved with the classic substrate/Al/SiO2/TiO2 structure wherein the substructure SiO2/TiO2 perform as reflectance enhancement and protective layers. Compared with day light optimized mirror products, the efficiency for the LED spectral range is increased up to 4% by SMMT’s technology of selective coatings on metal strip.


Above 425nm Al mirror products come with a very stable reflectance over a wide wavelength range. At characteristic wavelengths for CoB-LED applications such as ~450nm for blue LED chip, ~550nm for white LED phosphors and ~625nm for yellow LED phosphors is the reflectance is extreme high.
