Lighting the way ahead
Flashlights play a central role in the lives of the citizens of a world of light. Most advanced modern flashlights are LED-based. LEDs (light-emitting diodes) are more efficient than incandescent bulbs. In 2014, the invention of efficient blue 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 to raise global awareness of the achievements of light science and its applications, and their importance to humankind.
The success of the International Year of Light was followed by a proclamation of an International Day of Light in a resolution prepared and adopted by the UNESCO Executive Board at its 200th session at the UNESCO HQ in Paris, France, on September 19, 2016. The UNESCO Executive Board resolution was endorsed by the UNESCO General Conference at its 39th session on November 7, 2017. Since then, the International Day of Light is held on May 16th every year.
