Defining the Spectrum for Unique Lighting Applications, TM-30-15 and Human Centric LED Sources

Today’s novel, new LEDs spectrums and CCT tunable LEDs require more complex methods for characterizing “quality of light.” Too many lighting specifiers today are struggling with a supply chain using legacy specification methodologies derived from over a century of conventional bulb technology. As we close the door on traditional bulb use, new LED lighting technology offers beautiful options which require our industry to leave behind today’s lingering, outdated standards such as ANSI bins and CRIs. Tunable light sources enable the user to create unique environments to match the season or even the time of day. Innovative phosphor blends, pumped by violet, blue, and cyan, are creating new spectrums never seen before, where whites are whiter, colors are richer, and efficacies are saving even more energy. Chromaticity targets can move freely above or below the BBL, and spectrums can be tuned to match our growing understanding of human photobiological needs as well as the needs of the various plants we consume. Merchandise in retail stores can look even more appealing, pedestrians can feel safer, patients can heal faster, and workers can be more productive. There are challenges in how to specify these innovative new LED sources. This talk will explore some of these new LEDs and review how new standards, such as TM-30-15, CQS, PAR, PPF, melanopic ratios, and GAI are struggling to keep up with the rapidly evolving industry.
