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 of heat away from the LED junction.Different materials can be used for this purpose, such as alumina, aluminium nitride, and silicon.Diamond has also been gaining momentum for demanding heat management applications.In ENHANCED COLLAGEN POWDER WITH MATCHA order to evaluate the impact of the copyright material on the reliability of the devices, the junction temperature of Cree white XLamp XB-D LEDs was obtained with Ansys for various carriers and different LED current levels.
The impact of the junction temperature on the LED’s lifetime, emission intensity, footprint, and wavelength stability was then COLD FLU RESCUE evaluated for each copyright based on the datasheet of the devices.The results provide additional knowledge regarding the impact of the copyright on the performance of the LED.
