Dr. Tessa Pocock is an invited Panelist at the Plenary Session of the DOE SSL R&D Workshop to be held on Tuesday, January 31, 2017, at 10:30 am at the Hyatt Regency Long Beach, CA.  This Panel, entitled “ENGINEERED LIGHT: ACTION SPECTRUM AND BEYOND” will explore the use of engineered light — light whose spectral intensities are tailored in time and space — to accommodate various applications and the action spectra associated with those applications.  Solid-state lighting offers new levels of engineering control over light spectra, but we almost exclusively consider the photopic “action spectrum” associated with the standard human observer when developing products/solutions and specifying/defining the lumen content of light. In fact, as low-cost, engineered solid-state lighting becomes more and more available, different ways in which light will be used will require consideration of different action spectra: human melatonin response, museum-art degradation, cameras for machine vision, plants, animals, etc. Moreover, action spectra interact with other characteristics of light (intensity distribution in time and space) that may also be engineered. Dr. Pocock will bring her extensive knowledge of lighting and its impact on plant physiology, plant yield and nutrient quality.
