Newly Released IEC 63013:2017 for Measuring the Luminous Flux Maintenance of LED Packages

Untitled-1

The International Electrotechnical Commission (IEC) has released IEC 63013:2017.  This standard applies to LED packages – Long-term luminous and radiant flux maintenance projection and is now available on the IEC webstore.

Description: “IEC 63013:2017 is applicable to LED packages for general lighting services. It specifies procedures and conditions for measuring the luminous flux maintenance of LED packages. It also provides the procedures and conditions (criteria) of projecting the long-term luminous flux maintenance based on limited luminous flux maintenance test data collected. Within the context of this document, wherever luminous flux measurement data is specified, radiant flux measurement data can also be used.”

Near and Far Field Measurements with a Vector Network Analyzer

For optimal performance in over-the-air RF systems, antennas must meet specific requirements. Performance parameters like size, wind-loading, environmental ruggedness, transmission pattern, bandwidth, and power handling capability should be considered. Methods of measuring the transmission (or reception) pattern that determines antenna gain with a VNA will be examined in this article.
