Norman Bardsley is a member of the Technical Advisory Team for the Solid State Lighting (SSL) Program of the US Department of Energy (DOE). In this role he is a co-author of the DOE’S SSL R&D Plan, helps to set the agenda for the annual R&D Workshop and manages research projects. Norman also acts as Chief Analyst for the International SSL Alliance. Following the award of an M.A. Degree in Mathematics at Cambridge University and a Ph. D in Theoretical Physics from the University of Manchester, Norman served as Professor of Physics at the University of Pittsburgh, Strategic Business Development Manager at Lawrence Livermore National Laboratory, Director of Roadmaps and Standards at the US Display Consortium and Director of Display Technology for DisplaySearch.
LEDification: A Work Still in Progress
Despite an excellent start, the development of solid state technology to provide high-quality light at affordable cost for all important applications across the globe is far from complete. Substantial advances are still needed in efficiency, colour mixing, beam shaping and quality control. International cooperation is required to ensure that the full benefits are available in developing economies, especially in areas without access to the electrical grid. This paper explores the opportunities for further R&D, reformed practices in manufacturing and distribution, education and training, so that the quality of artificial lighting can reach its full potential and be made available across the globe at an affordable cost.
