En 2014, Isamu Akasaki, Hiroshi Amano et Shuji Nakamura ont reçu le prix Nobel de physique pour « l'invention des diodes électroluminescentes bleues efficaces, qui a conduit à des sources de lumières blanches brillantes et énergétiquement économes ». En effet, au cours de ces dernières années, les diodes électroluminescentes (LEDs) ont progressivement pénétré le marché de l'éclairage domestique, ainsi que d'autres marchés de masse. Cet article vise à donner un point de vue sur la physique des LEDs, sur les inventions-clés qui ont conduit au prix Nobel 2014 et sur les perspectives d'économies d'énergie que les LED pourraient permettre.
In 2014, Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura received the Nobel Prize in Physics for “the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources”. Indeed, in the recent years, Light-Emitting Diodes (LEDs) have progressively made their way to the home lighting market, as well as to other mass markets. This article aims at giving an insight on LEDs physics, on the key inventions that led to the 2014 Nobel Prize and on the prospects for energy savings that LEDs could allow.
