Boron nitride is an excellent heat conductor and electrical insulator with overall cost reduction while improving physical properties at lower loading.

How to manage heat dissipation in LED applications

LEDs are efficient lighting sources compares to other sources as it:

last longer last longer
Cost less cost less
empower more lumens per watt empower more lumens per watt

Even though the operating temperature is lower with LEDs, they still produce some heat which can negatively affect their efficiency. This heat is produced by electrical energy that is not converted to useful light but is conducted to outside ambience. Further, LEDs are encapsulated in a transparent resin, which is a poor thermal conductor.

To ensure a lower operating temperature for the device and dissipate the heat, heat sinks provide a path for heat from the LED source to the outside through conduction. Proper heat dissipation of an LED will help to ensure its consistent quality and performance by preventing failure, thus extending the lifespan of the LED, and will also enable the LED to emit more light.

Boron Nitride (BN) is a unique ceramic material that can improve thermal conductivity while remaining electrically insulating. It is, therefore, an attractive alternative to metal, which often requires additional parts or treatment to obtain electrical insulation properties.

BN-based thermoplastics heat sinks provide:
  • Thermal conductivity and electrical insulation combination
  • Potential replacement of over-engineered metal-based thermal management systems
  • Good chemical and corrosion resistance for long term service
  • Production cost reduction vs. aluminum
  • Weight savings
  • Lower cost through higher design freedom
  • Color freedom
