As product designers develop higher powered LEDs for the lighting, medical and home entertainment product markets, thermal management increasingly becomes an obstacle.

Heat sinks have a significant impact on how LED fixtures perform. They affect the life, power consumption and light output of the fixture. The first part of the presentation will discuss material and design options available to LED fixture designers to help minimize the junction temperature and optimize overall performance. Design tools will be presented that help predict and compare junction temperatures between various heat sink designs. A case study will be used to highlight the real-life benefit of these tools. Additionally, advanced cooling technologies available to meet extremely challenging applications will be presented.

To bring high powered/high brightness LEDs to market, an active cooling solution can greatly aid in applications that use many tightly packed LEDs, have a small volume or surface area where natural convection is inadequate or that are located where the ambient temperature is high. Active cooling allows the lumen output of individual LEDs to increase without the repercussion of thermal damage or lower life expectancies. Heat is a killer for LEDs and active cooling allows lumen output today not projected possible for years down the line. The second part of the presentation will discuss how active cooling in conjunction with passive aids innovative product designs and overcomes LED thermal barriers.
