The First-Level Optics Technology in LED Lighting

摘要

The first-level optical technology associated with LED packaging is discussed in this article. The first is a precise optical modeling technology for LED light sources, which is based on midfield fitting technology, and can be applied to build up a precise optical model for advanced illumination design. The second is a phosphor modeling technology. We start the modeling from scattering property. Through the study of absorption and conversion in phosphor, we can precisely describe optical distribution of yellow and blue lights with Monte Carlo ray tracing. The two precise optical modeling technologies in the first-level optics have played important roles in LED lighting, and also benefit industry.
