A new method for modeling the spatial radiative characteristics of light-emitting diodes using Monte Carlo photon tracing has been proposed. The
key advantage of this approach is its ability to model radiative characteristics directly from manufacturer-provided datasheet emission patterns, eliminating the need to simulate photon trajectories through the complex internal physical structure of light-emitting diodes, which would ideally require tracing photons from their generation origin to their exit from the LED surface. The proposed approach simplifies the overall modeling process without losing preciseness of mimicking the real LED emission pattern. To illustrate the flexibility and versatility of the proposed method, simulations were conducted for LED devices from three different manufacturers, demonstrating its effectiveness across varying designs.
