Ceramic Phosphors

CERAMIC PHOSPHORS FOR IMPROVED HIGH-BRIGHTNESS LEDS

CoorsTek ceramic phosphors improve the output, color consistency, efficiency, and lifetime of high-brightness light emitting diode (LED) lighting. 

High-Brightness LED Challenges

By incorporating cerium-doped yttrium alumina garnet (YAG:Ce) phosphor within a composite ceramic matrix, CoorsTek addresses the primary enemy of high-brightness LED devices: heat.

Excess heat shortens LED life, creates color variation, and reduces both intensity and efficiency. 

Leveraging the superior mechanical and thermal strengths of ceramic, CoorsTek phosphors deliver a robust, stable, high thermal conductivity solution for improved high-brightness LED performance and reliability. 

Example Applications

LED technology is maturing every year, providing ever-brighter LEDs in smaller, hotter spaces. A growing variety of high-output LED applications will benefit from CoorsTek ceramic phosphors including:

  • automotive headlamps
  • projection displays
  • outdoor lighting

Performance benefits:

  • Improved thermal management
  • Higher, more uniform intensity
  • Enhanced color consistency
  • Better efficiency
  • Longer useful life
