HOT TOPIC FOR LEDS: STANDARDIZATION ISSUES OF THERMAL CHARACTERIZATION

摘要

The paper discusses the increasing need for a more sophisticated thermal characterization of LEDs and LED-based products. The major concern is how to provide meaningful thermal metrics of high power LEDs and what other thermal related data should be provided on products' datasheets that would allow lighting system designers design efficient and reliable products. The paper is the condensed and revised version of a white paper [1] about the topic prepared for the EIA-JEDEC JC15 committee on standardization of thermal characterization of packaged semiconductor devices and provides a status report on the latest steps taken by the committee in this field.
