Next-Generation Phosphor Solution for High-Power LEDs
Solid-State Phosphor Encapsulation for Harsh Environments
It is designed for high-power LED applications that demand long-term reliability.
Compared to traditional silicone binders, PiG ensures much better color stability.
With our custom low-temperature frit technology, we enable safe sintering of even red phosphors that are prone to heat damage.
This makes our PiG chips a reliable solution for advanced LED designs.
Why Replace Phosphor in Silicone with PiG?
Glass-Based Stability for Long-Term Performance
PiG is a solid-state phosphor solution that solves the reliability issues commonly found in silicone binders (PiS).
While PiS materials degrade under high temperatures and humidity, PiG maintains its structural and optical integrity over time.
Low Firing Temperature
Our frit and paste enable secure bonding at low temperatures, protecting sensitive components from thermal damage.
RoHS & REACH Compliant
All our materials are 100% lead-free, fully compliant with RoHS and REACH standards for global environmental safety.
Multiple Forms Available
Choose from powder, paste, or sintered preform formats, depending on your process requirements and equipment.
Tuned for Your Process
We tailor thermal expansion (CTE), glass transition temperature (Tg), and viscosity to perfectly match your specific application.
