Solving the system-level thermal management challenges of LEDs

Thermal management is critical to LED performance and life, so mechanical designers need to consider thermal issues from the earliest stages of the development process, writes John Parry of Flomerics.

In referring to LEDs, the US Department of Energy (DOE) states that no other lighting technology offers so much potential to save energy and enhance the quality of our building environments.

Thermal management is critical to LED performance because the lifetime is a function of junction temperature. Rudi Hechfellner, applications manager for Philips Lumileds Lighting, says that thermal management is by far the most critical aspect of LED system design.

LED system manufacturers are addressing this challenge by seeking out improved heat sink designs, high efficiency circuit boards, high thermal conductivity enclosures and other advanced thermal design techniques.

Thermal simulation is playing an increasingly important role through its ability to evaluate various alternatives and optimize the system-level design from a thermal standpoint prior to the prototype phase.
