October 13, 2025

As highlighted in Tech Xplore article “Study maps three decades of white LED progress and key innovation drivers”, tracing how white light-emitting diodes have evolved since their commercial release in 1996.

The study, conducted by researchers from the University of Cambridge and ETH Zurich, reveals how white LEDs—now central to efficient lighting systems—benefited from decades of R&D, innovation spillovers, and advances in semiconductor manufacturing. The paper identifies LED progress as a combination of performance breakthroughs driven by R&D and cost reductions achieved through manufacturing scale and process improvements.
