PiG LED Packaging

Where Glass Makes a Difference in LED Packaging

As LED technology pushes for higher brightness, tighter color control, and longer lifespans, packaging materials must meet new levels of reliability.
YEKGLASS supports this evolution with robust inorganic materials engineered for extreme conditions and long-term optical clarity.

Automotive Lighting

Automotive Lighting

Headlamps, DRL, tail lights require high thermal and mechanical stability.

Horticulture LEDs

Horticulture LEDs

Red & deep red LEDs for plant growth need phosphors with thermal protection.

COB Modules

COB Modules

Chip on board packages demand strong seals and consistent color output.

Medical & Industrial Lighting

Industrial Lighting

Harsh environments call for moisture proof, temperature resistant sealing.


Why Use PiG - A Better Way to Stabilize Light

PiG (Phosphor-in-Glass) is a revolutionary alternative to silicone based phosphor binders.
By embedding phosphors in a low temperature glass matrix, we ensure superior resistance to heat, moisture, and aging critical for red and high power LEDs.

High Temperature Stability

High Temperature Stability Glass Package

Operates reliably under extreme thermal conditions. Perfect for high power LEDs that generate significant heat without risking performance degradation.

No Yellowing or Color Shift

No Yellowing Glass Packaging

Maintains original color over time. Ensures consistent color output even after prolonged use in harsh environments.

Optimized for Red Phosphors

Optimized for Red Phosphors

Ideal match for sensitive red phosphor materials. Especially suited for CaAlSiN₃:Eu²⁺ and similar compounds requiring low processing temperatures.

Customizable Properties

Adjustable shape, thickness, and color coordinates. Engineered to meet specific design needs, including targeted CIE color bins and light uniformity.

Which Material Lasts Longer?

Looking to improve thermal durability or optical performance in your LED applications?
Our team can support you with tailored glass solutions for next-gen lighting systems.

Let’s Build the Future of LED

LED packaging involves multiple sensitive materials from phosphors to substrates that may degrade at high processing temperatures.
YEKGLASS’s low temperature frits allow hermetic sealing at 300–350 °C, preventing thermal damage while maintaining strong adhesion and precise control.
This makes it especially suitable for next generation LEDs using red phosphors or COB assemblies.
