Impact of Die Carrier on Reliability of Power LEDs

High power light emitting diodes (LEDs) suffer from heating effects that have a detrimental impact on the devices characteristics. The use of LED carriers with high thermal conductivity promotes extraction heat away junction. Different materials can be used for this purpose, such as alumina, aluminium nitride, and silicon. Diamond has also been gaining momentum demanding management applications. In order to evaluate carrier material reliability devices, junction temperature Cree® white XLamp® XB-D LEDs was obtained Ansys various different current levels. LED’s lifetime, emission intensity, footprint, wavelength stability then evaluated each based datasheet devices. results provide additional knowledge regarding performance LED.
