Waterproof Color LED Tape Light Kit The inventors of the blue LED were recently awarded a 2014 Nobel Peace Prize in Physics. They are Dr. Shuji Nakamura, Isamu Akasaki and Hiroshi Amano. Here's why this invention matters: With light, red, green and blue combines to create white. While red and green LEDs have been around for decades, creating a blue one has been much more difficult for scientists. Image from Wikipedia Red, green and blue light combine to create white With the addition of blue (and thus white light) to the palette of available LED colors in the mid-90s, an entire new market for indoor and outdoor home lighting suddenly opened up. Explains Nakamura, "I hope that energy-efficient LED light bulbs will help reduce energy use and lower the cost of lighting worldwide."  This nifty graphic by Johan Jarnestad illustrates the increase in lumens-per-watt that LED enables: Image from Interior Design LED is more energy-efficient than options from years past On the basis of this increased efficiency, LED is appearing everywhere these days, from stunning fixtures to everyday  LED desk lamps and  energy-efficient replacement bulbs : Gravy Oak with Matte White Koncept Desk Lamp , Warm White LED 2700K Dimmable Light Bulb , Klein Chrome Contemporary LED Possini Euro Pendant Light If recent trends are any indication, LED lighting is the wave of the future indeed. And for all the innovative and attractive light designs that it has enabled, the Blue LED is indeed an invention worth rewarding.
