Abstract

The far-field pattern of light-emitting diodes (LEDs) is an important issue in practical applications. We used a Monte Carlo photon-tracing method for the package design of flip-chip bonded power LEDs. As a first-order approximation, we propose using a plane light source model to calculate the far-field pattern of encapsulated LEDs. The far-field pattern is also studied by use of a more detailed model, which takes the structure of all epitaxial layers of a flip-chip bonded power LED into consideration. By comparing the simulation results with the experimental data, we have concluded that the plane light source model is much less time-consuming and offers fairly good precision for package design.
