7th October: National Led Light Day

National LED Light Day has been observed on October 7th to recognize and celebrate the advancements of one of the most important scientific achievements in recent history, the development of blue light-emitting diodes We are all born as incredible detectors of light. We intuitively notice differences in color and brightness. And lighting professionals know that much of human sensation is visual. People respond emotionally to light and color, using its consistency to draw us in, like moths to a glowing light. The power of LED lighting affects all of us in emotional, economic, and environmental ways, too. On October 7, 2014, Isamu Akasaki, Hiroshi Amano and Shuji Nakamura received the Nobel Prize in Physics for the development of blue light-emitting diodes. The earliest LEDs created in the late 1950s and early 1960s produced only a red-colored light. Slowly researchers developed other colors, but blue stumped them. Its shorter wavelength proved harder to reproduce. With Akasaki, Amano, and Nakamura’s invention, white LEDs were now possible. Bridgelux founded National LED Light Day in May of 2016 to recognize one of the most important scientific achievements in recent history.
