Video: Three Steps to Improved LED Light Measurements: Power

Improving LED Light Measurements

Jeff Hulett, Vektrex CTO, narrates this three part webinar series on how to improve LED light measurements. Instrumentation and the selected measurement method are key factors to improving your measurements.

Sustained power is the foundation for LED light measurement. LED devices including COB, array, luminaires, emitters, and others are moving to higher power levels. Understanding the power limitations of current sources and source measure units (SMU) is important. For example, with many current sources, Keithley included, 1000W of advertised power does not mean that 1000W of sustained power is possible. In this first segment of the webinar series, Hulett teaches how to identify current source power limitations that may negatively impact your LED light measurements.

How Much Power Is Enough?

Continuous power conversion is required to supply the sustained power necessary for performance LED light measurements. SpikeSafe Performance Current Sources are available with voltages to 400V and currents to 40A. They provide continuous power conversion in DC and pulse modes; with no pulse width or duty cycle limitations. While continuous pulse method is optimal for light measurements, these performance current sources support all three LED test methods as documented by LED light measurement standards (IESNA LM-85, CIE TC2-063): DC, Single Pulse, and Continuous Pulse.

This webinar will help you learn how to improve your LED light measurements.
