Monetizing The Potential Benefts Of Solid-State Lighting
Lighting Research Center, Rensselaer Polytechnic Institute
Great strides have been made to reduce the cost of SSL for general illumination. Little progress has been made, however, to
increase the potential benefts that SSL might provide to society. A fundamental problem with the value proposition for SSL is that
only two benefts are formally recognized - lumens, as a measure of light itself, and CRI, as a measure of color quality. Signifcant
progress has been made in neurosciences since the lumen and CRI were defned such that we now have a better understanding
of how the human eye transforms optical radiation into neural signals that support color and brightness perception, visual
performance and circadian rhythms. New metrics based upon neuroscience research can be used to quantify the benefts
provided by SSL. By quantifying both the costs and benefts, the monetary value of lighting can be determined for each
application. By relying solely on the lumen and CRI as the only quantifable benefts, SSL will become another commodity product.
Mark Rea, Ph.D., is the director of Rensselaer Polytechnic Institute’s Lighting Research Center and a professor in architecture
and cognitive sciences. He conducts research in many areas including circadian photobiology, mesopic vision, psychological
responses to light, lighting engineering, and visual performance. He is the author of more than 250 scientifc and technical
articles related to vision, lighting engineering, and human factors and was the editor-in-chief of the 8th and 9th editions of the
IESNA Lighting Handbook. Rea is a recipient of the IESNA Medal. His recent book, Value Metrics for Better Lighting, brings together
a wide range of research to illustrate how the effective use of light can beneft society and the environment.
Actions That Really Matter
Senior Vice President, Toshiba International Corp. & Chief Venture Executive, Toshiba LED Lighting System Division
The 15th anniversary of the Strategies in Light conference is a good time to pause momentarily to take stock. What have we
accomplished, where are we going and are we living up to the promise of this solid state technology? Clearly our industry is
rapidly transforming as LED technology matures. But the fnal destination is not inevitable. It will be the result of critical and timely
choices made by leaders (both individuals and companies) who see the potential for meaningful change and act upon it. This
presentation will explore the challenges and the opportunities facing such leaders, including: lessons learned from rapid LED
adoption in Japan and other leading markets. It will also address the most powerful triggers of change that exist outside our
industry – fve technologies and fve game-changing forces you can’t afford to ignore - as well as key success factors that have
enabled companies to win in rapidly changing industries.
