Smart, Sustainable Lighting – The oncoming revolution of Solid State Lighting

Prof. Venkat Venkataramanan

Director, Scientific Operations
Institute for Optical Sciences
University of Toronto, Canada


Venkataramanan is the Director, Scientific Operations of the Institute for Optical Sciences at the University of Toronto and the Director of Smart Sustainable Lighting Network (SSLNet). He heads the photometry and Solid State Lighting labs and is one of the lead investigators in the entrepreneurship education program at the IOS. Following his doctoral degree in Physics from the Indian Institute of Science, Bangalore, he worked as a Scientific Officer at Atomic Energy, India. He then held various research and teaching positions in the UK, India, Portugal and Japan. He was a Leverhulme Commonwealth/USA Visiting Fellow and a Japanese Government Science & Technology Research Fellow.

Venkat is an Adjunct Professor in the Department of Electrical and Computer Engineering at Ryerson University in Toronto. He is also the founder and Chief Technology Officer of Lumentra Inc that develops nanophosphors for LED applications. He is the president of Canadian National Advisory Committee member of the International Commission on Illumination (CIE). He is also strongly interested in science outreach. He has co-hosted science talk shows in radio and television for about 4 years.

Talk Abstract

Since Edison commercialized the light bulb more than a century ago, improvements to lighting technologies have come exclusively in the form of higher efficiency light sources while the overall system of lighting control has remained largely unchanged. The advent of solid state lighting technologies presents an opportunity to not only significantly increase the efficiency of our light sources, but also fundamentally change the way we deploy, monitor and control our lighting systems. Both LEDs and OLEDs have low power consumption, offering potential reduction of electricity used in lighting by 35% by 2030, have ultra-long lifetimes, use significantly fewer toxic chemicals during production, and leave no hazardous end products. Also, new digital smart systems can sense, analyze, adapt, and control our lighting in ways that were impossible with older technologies while presenting new opportunities for greater energy efficiencies and improved lighting quality.

This talk will feature some of the recent advances in fundamental science and technology that are rapidly transforming lighting. Some of our own work in this area will be highlighted.
