Show Me the Data: Characterizing the Performance of Color Tunable Light Sources
June 4, 2020 @ 12:00 pm EDT
June 4th 12:00 PM ET
Color tunable light sources provide tremendous flexibility in terms of spectral power distribution, but the resulting range of variation in chromaticity, color rendition, and other characteristics poses a challenge for product characterization and specification. The millions or billions or trillions (or more!) of spectral power distributions that can be created from one luminaire enables designers to meet various design intents and influence the visual appearance of spaces. However, in contrast with characterizing the performance of a fixed-output luminaire, there are no established methods or guidelines for characterizing performance over the tuning range for the variety of SPD-related metrics, which can impede engineering and specification of color tunable products. Using a massive dataset generated with high-performance computers, this webinar will discuss new methods to convey the extent to which color rendition can be varied, and how different factors (number of LED channels, typed of LEDs) influence the range of performance.
Webinar participants are eligible for one (1) IES Continuing Education Unit (CEU).
