Specifications and Benefits

  • Super-strong and very light-weight with +/-2.5% uniformity in white CCT
  • High light extraction and high surface thermal conductivity
  • High chemical resistance to oils, mild acids, alkalis, and water
  • User-customizable to various sizes and shapes with high curling and wrinkle resistance
  • Can be thermoformed into 3-dimensional shapes using thermoplastic substrates
  • Can be printed on and patterned using conventional digital printers or screen-printing
  • Available with different colors as well as standard white, CCT, and CRI properties, including ultra-high CRI >95
  • Can be custom-produced in both monochrome or RGYOB patterns
  • Can offer significant cost-savings compared to traditional phosphor coating methods when used on chip or package levels.
  • Works as is or with a variety of adhesives, epoxies, and silicone
  • With or without high performance adhesive layers (acrylic or silicone)
  • High power density and high temperature operation
    • – Will operate ~150° C for short periods (hours) and 100-125° C for long periods
    • – Can be used with a wide range of substrates for all power levels
    • – Custom silicone-based versions can operate as high as 260° C
    • – Lower temperature limit: -40° C
