Dr. Steven Lockley, Harvard Medical School

Dr Steven Lockley is a Neuroscientist in the Division of Sleep and Circadian Disorders at Brigham and Women’s Hospital, an Associate Professor of Medicine at Harvard Medical School and a Professor in the School of Psychological Sciences at Monash University in Melbourne, Australia. He received a BSc in Biology from the University of Manchester, and a PhD from the University of Surrey in 1997.
Dr Lockley has 20 years experience on sleep and circadian rhythm research, and is a specialist in the effects of light on the circadian pacemaker and other ‘non-visual’ responses to light in sighted and blind individuals. He has studied the role of light timing, duration, intensity, wavelength and history and most notably to date, the wavelength sensitivity of the circadian photoreception system, helping to confirm the remarkable earlier discovery of a novel non-rod, non-cone short-wavelength sensitive photoreceptor in ganglion cell layer of the human eye. He is currently ground testing tunable LED lighting on behalf of NASA for installation on the International Space Station. He has published more than 100 original reports, reviews, chapters and editorials on sleep and circadian rhythms and his research is funded by the NIH, NASA and others. He recently co-authored ‘Sleep: A Very Short Introduction’ from Oxford University Press.

Human Centric Lighting: How biology and technology can work together to improve alertness, sleep and health

The eye has dual roles in detecting light to allow us to see, and to stimulate a number of non-visual effects of light including resetting the circadian clock, suppressing the pineal hormone melatonin, and directing alerting the brain. These visual and non-visual effects of light utilize functionally and anatomically distinct photoreception systems, including different photoreceptors and the independence of these two systems means that light properties, including intensity, spectrum, and pattern, can be manipulated to differentially stimulate either, or both, sets of responses. In practice, lighting should be designed to optimize both visual and non-visual effects and this can be achieved by using tunable lighting systems that can vary the spectrum, intensity and timing of light output. Dr Lockley will review the neuroscience of light detection, the biological impact of light and example applications of the non-visual benefits of light.

Light in the Head – what Human Centric Lighting can learn from Neuroscience and apply in the field

Much of illumination design and science are concerned with the delivery of optimal lighting conditions to the human eye. But what happens after light enters the eye? There are many more effects than those involving vision, sleep, and circadian rhythms. This presentation will use an “inside-out” approach to consideration of effects of light, by taking a look at how the human nervous system works, and how light is involved in non-visual responses.

Light exposure through the eye is known to exert a powerful effect on the brain and body, comparable to that of many drugs. Yet most forms of light exposure are not regulated as medical devices or therapies. However, new LED illumination and control technologies are starting to reach the market which more accurately replicate daylight exposure. Scientists, doctors, designers, and engineers need to be aware of the unexpected effects of illumination from these lighting systems in order to anticipate beneficial and detrimental effects upon patients and staff.

He has written 42 academic papers, 91 articles, 6 book chapters, and a book – Radiosity: A Programmer’s Perspective – that today is the foundation of Lighting Analysts’ AGi32 and ElumTools lighting design and analysis software.
His current research interests include circadian-based lighting design and analysis. In particular, the capabilities of today’s software tools for architectural lighting design need to be extended to encompass spectral power distributions, non-visual spatial responsivity of the human eye, and temporal aspects related to human-centric lighting.

Melanopic Illuminance: Designing a Virtual Photometer

Melanopic illuminance is a key concept of circadian-based lighting. While it is conceptually simple – basically photopic illuminance with a different spectral weighting –- it poses a number of unique design challenges for today’s architectural lighting design software. In this workshop, we explore four design requirements for a virtual melanopic illuminance meter:

1) Spectral and spatial responsivity;
2) Spectral power and reflectance distributions;
3) Temporal response; and
4) Climate-based daylight integration.

These requirements in turn will necessarily redefine how architectural lighting design is performed using software tools.
