Abstract :
We study by simulation the current spreading, heat transfer, and light emission in a high-power light-emitting diode (LED) with an interdigitated multipixel array (IMPA) chip design. The applied hybrid approach allows coupled modeling of various processes involved in the LED operation, providing good agreement with observations.
