LEDs Spatial Radiation Pattern

[Marian VladescuParticipant]

Is the LEDs spatial radiation pattern taken into consideration in OptiSPICE models available for LEDs?

Hi Marian,

Yes it is. The spatial information is held under the Mode Shape parameters. These are defined in most of the models. You can define spot size, etc.

For propagation of the light from the LED, a free space component can be used to simulate the Fresnel diffraction integral (so you can model an LED coupling to a fiber for example).

Good info for my LED design in the near future 🙂
