Thermal Management with Altair Product Design support: Ceramic simplifies Heat Dissipation within LEDs LEDs suffer heat problems limiting their success as a light source. To improve the heat characteristics of LEDs much attention is given to the heatsink, less to the layers and barriers between LED and the heat dissipating surface. A change of concept and material, as carried out in a consulting project by Product Design, an Altair business unit, for CermTec AG shows how significant gains in thermal management and reliability as well as a simplified system can be reached. As shown in the consulting project, using ceramics as heatsink, circuit carrier and part of the product design opens the chance to overcome traditional patterns. A simulation process based on Computational Fluid Dynamics supports thermal optimization and technical product design. Within the following case study we will show how the new theoretical approach works, validate the concept and describe how improvements with ceramic heatsinks can be achieved. Download PDF
