If the LED is thin layer structure without nano structure, using stack functions are easier, faster and more accurate without discretization error:

stackpurcell - Script command ÔÇô Lumerical Support
stackdipole
Stack dipole half-space
Example can be found here Micro-LED ÔÇô Lumerical Support

If there is nano structure, FDTD simulation must be used. OLED examples can be references:
