Description: LED light sources have progressed dramatically in the last decade. But one tough nut to crack is flicker, or more formally, Temporal Light Artifacts. Only a small percentage of LED luminaires flicker, but when they do, it can lead to distraction, headaches, malaise, and annoyance. Flicker metrics are not fully predictive, and we can’t eliminate flicker until we have better metrics. This talk will address why LEDs are more prone to flicker than conventional sources, how to spot flicker, and how to avoid it.
Speaker Bio: Naomi Miller straddles the line between design and engineering at the Pacific Northwest National Laboratory in Portland OR. Called a “Senior Scientist,” she uses her decades of experience in architectural lighting design in Upstate New York and San Francisco to educate clients, customers, and practitioners and help nudge the SSL industry toward better, more practical solutions. Researching and reporting on lighting quality issues such as visual comfort, flicker, and light distribution with respect to SSL products, she is the tedious voice of experience. By bridging the gap between technology and application, she can promote the wise use of LEDs, working with industry to overcome the hurdles and celebrate the opportunities.
She has too many years of experience working in different facets of the lighting industry, but still finds lighting to be an intriguing mélange of economics, human factors, and physics; an essential element of productivity and comfort; and a visual delight. She serves on the Illuminating Engineering Society’s Board of Directors and is both a Fellow of the IES and the IALD.
