Optimizing heat transfer can be critical in lighting equipment, e.g. PCBs and heat sinks. In such applications, an accurate prediction of convective heat transfer is essential. The diffusion of heat in solids and/or heat transfer by radiation can play an important role.

Usefulness for Luminaire Manufacturers

The simulation of heat transfer and radiation can be of particular interest in luminaire development. Optimizing thermal management can be vital to improve the lifespan of a lighting device. Due to the complexity of this subject, most SME luminaire manufacturers will outsource thermal simulation tasks however.
