LED multiphysics modeling for “Industry 4.0”, an approach proposed by the Delphi 4LED European project

The Industry 4.0 initiative targets the digitalization of design and manufacturing processes. The aim of the Delphi 4LED project of the EU is to trigger this transition in the solid-state lighting industry by developing testing and modeling methodologies aimed at multi-domain characterization of LED based products. In this paper we present the concept and describe our approaches in modeling to create the appropriate “digital twins” of LED packages, modules and luminaires to be used in virtual prototypes applied in different system level design tasks.
