And Then There Was Light
And Then There Was Light

Inverted X-ray image obtained with Nikon's XTH225 CT system depicting the evolution of lighting (from left to right: candle, Edison style incandescent light bulb, fluorescent light bulb, LED light bulb). In 2014, the invention of efficient blue light-emitting diodes (LEDs) was awarded the Nobel Prize in Physics. Subsequently, the United Nations declared the year of 2015 the International Year of Light and Light-based Technologies. —Herminso Villarraga-Gómez, Nikon Metrology Americas & University of North Carolina at Charlotte U.S.A.
