Next-Generation Phosphor Solution for High-Power LEDs
Solid-State Phosphor Encapsulation for Harsh Environments
It is specifically designed for high-power LED applications where long-term reliability is critical.
Compared to traditional silicone binders, PiG offers significantly improved color stability.
Our custom low-temperature frit technology allows safe sintering of red phosphors that are otherwise vulnerable to heat.
As a result, YEKGLASS PiG chips provide a stable and dependable solution for advanced LED lighting systems.
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.
While PiS materials degrade under high temperatures and humidity, PiG maintains its structural and optical integrity over time.

Red Phosphor Compatibility
Thermal-Safe Red PiG with Custom Low-Temperature Glass
Red phosphors like CaAlSiN₃:Eu²⁺ are highly sensitive to heat and easily degrade in traditional sintering environments.
YEKGLASS solves this challenge by using specially formulated Low Melting Glass, which enables PiG sintering at just 250–350 °C.
“High transmittance and refractive index in the blue-violet region enhances LED photoluminescence efficiency.”
YEK Glass’s low-melting glass material is engineered for optimal optical performance.
This ensures strong photoluminescence and allows safe sintering of heat-sensitive red phosphors without degradation.
“Thermal stability and low glass transition enable sintering at reduced temperatures.”
