ARLINGTON, VA -- Jedec has published a new series of standards for component-level testing of high-brightness/power LEDs.

The JESD51-5x series addresses the previous lack of widely accepted thermal testing standards for power LED components. According to Jedec, published data sheet information was often questionable, even while use of high-brightness/power LEDs as a lighting source has become widespread, making thermal design critical in order to ensure expected LED lifetimes and light output.

The new standards include recommendations for which data to include on LED data sheets, as well as test environments and procedures defined specifically for power LEDs, removing previously existing ambiguity about how thermal performance of an LED package or a metal core printed circuit board assembled LED device is identified.

The series is in compliance with the International Commission on Illumination’s LED measurement recommendations, and are available for free download via the Jedec website.
