Selwyn’s Professor Sir Colin Humphreys will be giving a public lecture in Cambridge about the next generation of LED lighting on Monday February 9th. Titled “Lighting the future”, it will take place at 6pm in the Bristol-Myers-Squibb lecture theatre in the Department of Chemistry. Sir Colin is Professor and Director of Research in the Department of Materials Science and Metallurgy, and a Fellow of Selwyn.



He describes his theme:



“Gallium nitride is a remarkable new man-made material which is arguably the most important new material since silicon. Its use in LED lighting has the potential to save 10-15% of all the electricity we use. Research on low-cost GaN LED lighting by my group is currently being exploited by Plessey who are manufacturing such low-cost LEDs in the UK. GaN also has low energy consumption for power electronic devices, which could save another 10% of electricity use. Deep-ultra-violet LEDs made from GaN can kill all viruses and bacteria, hence have huge potential for water and air purification, which could save millions of lives in the developing world. Finally, lighting using optimised GaN LEDs really could improve not only our health but also students' exam results!”
