Metrics in Motion: Flicker & Glare
About this Course
The IES offers Educational Webinars throughout the year, purposefully spanning a broad range of topics and speaker expertise. Metrics in Motion: Flicker & Glare was a live webinar, now available as an archived webinar and CEU course.
Description: Flicker and glare are visual phenomena that have several things in common: both can range from mildly annoying to seriously disabling, both can be made worse by poorly designed LED lighting and better by good LED lighting, and both are the subject of research by PNNL that is helping to further industry-standard metrics, methods of measurement, and recommended practice. This webinar will provide an up-to-date evaluation of progress in addressing these critical lighting quality factors, their implications for energy-efficient LED lighting, and where additional research is needed.
By the end of this course learners will be able to...
1. Understand why LEDs (as wonderful as they are) have made the issues of glare and flicker more tricky, compared to conventional lighting technologies.
2. Learn some of the limitations and a proposed improvement to the UGR metric.
3. Acknowledge that flicker is an issue of the driver electronics and dimming systems, and compare several flicker metrics.
4. Learn some tips and tricks for identifying flicker from light sources.
Senior Lighting Engineer
Ms. Naomi Miller is a designer/scientist in the solid-state lighting program at Pacific Northwest National Laboratory in Portland OR. Working to bridge the gap between technology and application, Miller promotes the wise use of LEDs, and works with industry to overcome the hurdles where LEDs are not ready for prime time. Miller has received over 30 architectural lighting design awards for projects ranging from churches to university science buildings, boutique hotels, supermarkets, and parking lots. She chaired the IES Quality of the Visual Environment committee for 8 years and was a principal member of the writing team for Light + Design: A Guide to Designing Quality Lighting for People and Buildings (DG-18-08). She is a Fellow of the IES and Fellow of the IALD.
