Phosphor in Glass or PiG is a mixture of phosphors and a transparent glass matrix that offers several advantages for high power LED and laser projection applications. Conventional LEDs often use phosphors encapsulated in silicone or polymer resins, but those often have low thermal performance and poor stability at high power levels. The phosphor in glass approach can deliver superior thermal conductivity and temperature performance under high power densities. This results in improved luminescence efficacy and long term stability of the phosphor-converted LED (pcLED) or laser-excited phosphor (LEP) device.

We can fabricate and customize a variety of phosphor-in-glass and ceramic phosphor components that provide stable long-term and high power illumination for a wide range of applications.

A phosphor in glass component can be combined with a blue (or UV) laser and/or LED to generate broadband white with high color rendition (CRI>90) and a wide range of correlated color temperatures (CCTs), in addition, non-visible infrared radiation can also be produced using PiG components combined with light sources across the visible spectrum.

The design flexibility offered by our phosphor in glass processing  makes it an attractive and low-cost option for use in a wide range of high power lighting and projection display devices.
