Light-emitting diodes, also known as LEDs have become a common energy saver all over the world. Directly converting electricity into light and sparing heat-waste, they use much less energy than fluorescent bulbs, creating both heat and light. While the red LED was created in the 1950s, without the magic of the blue light, LED was not living up to its full potential. In 1992, three men, Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura produced the blue light-emitting diode becoming the most efficient and longest lifetime bulb at the time. They are now presented with the 2014 Nobel Prize in physics and we see their accomplishment everyday when we look at our own smartphones. Congratulations!!
