    Length: Approx. 80 minutes, including questions from Webcast attendees.

    OVERVIEW:

    Thermal management is a critical aspect of the design of almost every LED module, light engine, lighting fixture and display. Our speakers will discuss the fundamentals of thermal management and describe how simulation can assist with the design process. They will also discuss how the correct choice of thermal materials will help to make your product a success.

    WEBCAST DETAILS:

    LEDs can be the most components in a lighting product, but poor thermal design can lead to low light output, low reliability and even catastrophic failure.

    The first part of this Webcast will discuss the need for thermal management of power LED devices, and the need for standardization with respect to the thermal data supplied by vendors. Considerable care is needed when applying JEDEC standard thermal metrics developed for ICs to LED devices. Misunderstandings about what should be measured and reported, and how this data should be applied will be discussed since this can lead to significant errors in thermal design.

    Examples of the measurement techniques used by two of the leading LED vendors will be presented to provide an appreciation of both their expertise and the data they provide to customers. A recipe for system designers will be discussed and an example of system level thermal design shown to illustrate the overall approach.
