b"Automotive | Engineer InnovationIn the development of modern automotive headlights a variety of factors and challenges must be considered. One of which is thermal management. Reliable and predictable total thermal management can be achieved with modern simulation tools. This article is based on project examples from OPEL vehicles, demonstrating an insight into the CFD simulation and validation process with laboratory results. The objective of this work is to integrate different analysis topics in the development process, with a view of achieving an efficient simulation time to evaluate various concepts with significant results.In today's headlamp development, the link between innovative lighting functions and aesthetics plays a key role. New technologies, such as Intellilux LED Matrix light, must be integrated with the given design and the available installation space. In addition to optical light design, thermal management is also an integral part of the early concept phase. The evaluation of these numerous subject areas (Figure 1) within the development process, for each lighting concept (Figure 2), must be done in a short time. The fixed requirement within the lighting system is the design and optical performance. After this evaluation, thermal management should ensure that this is possible without restrictions of installation space and additional cost.Thermal AnalysisDe-IcingSun Load Analysis AnalysisThermal ManagementCondensationLED Analysis AnalysisHeatsink AnalysisFigure 1: Simulation topics13"
