Abstract

In this paper, we propose a novel LED modeling algorithm for precise 3-D light pattern simulation. Normalized cross correlation is proposed to to verify the validity of the simulation in 1-D intensity pattern as well as 2-D irradiance pattern in various mid-field distances. The model is demonstrated to obtain more than 98% in normalized cross correlation between the simulation light pattern and experimental measurement for a TIP LED emitter by Lumileds.
