The LED Utility™ accurately simulates novel LED structures and all materials involved. The utility simplifies common tasks associated with LED design and aids in the rigorous computation of extraction ratios and radiation patterns. It utilizes the RSoft CAD to describe the geometry and material properties and RSoft's flagship simulation tool FullWAVE to model the LED. The RSoft CAD interface is a fully parametric, highly flexible, and user-friendly design environment with 3D editing capabilities to simplify the description of complex LED geometries. The underlying FullWAVE simulation is based on the Finite-Difference Time-Domain (FDTD) algorithm which is an ab-initio approach for solving Maxwell's equations with no inherent approximation, which is well suited to accurately model the intricacies of an LED structure.
The LED Utility provides users of FullWAVE, RSoft's optical simulation tool, the functionality described here. All simulation tools are licensed separately.
