The current density of GaN-based light emitting diode (LED) plays a strong impact on the light output and heat transfer performances. In this paper, the finite element simulation software ANSYS is used to simulate the thermoelectric performance of LED chip with different electrode structures. The conventional LED chip and the flip-chip (FC) LED with bumps are compared in terms of the current density...
