The Physics Nobel Prize 2014 Awarded for the Invention of Blue Light Emitting Diodes (LEDs)!

The Nobel Prize in Physics 2014 has been awarded jointly to Isamu Akasaki, Hiroshi Amano, Shuji Nakamura, "for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources." 

The Nobel prize is awarded for an invention of the greatest benefit to mankind, the invention of the blue LED has fundamentally transformed lighting technology, red and green LEDs have been around for some time but without the blue LED, a white light could not have been created.
The first ever blue LEDs were made by the Nobel Prize winning trio in the early 1990s, enabling a new generation of high energy bright blue light, the basis for the new era of light bulbs. In addition to this, the development  of colour LED screens that most of you probably have in your televisions at home and your smartphone currently in your pocket.
The winners of this groundbreaking invention succeeded where everyone else had failed, in the industry and in the scientific community. They will share prize money of £0.7 million between them and will also be added to the prestigious list of 196 other Physics laureates recognised since 1901 when the Nobel Prize was first established.  Professor Olle Inganas, a member of the prize committee commented that this invention "would make Alfred Nobel very happy".
LEDs (literally) outshine traditional incandescent and fluorescent lamps, delivering better quality of light as well as a reduction in energy consumption. This improvement is as simple as this; traditional lighting whilst converting electricity into light  creates a wasteful mixture of heat and light whereas LEDs convert electricity directly into photons of light. 
One fourth of the world's electricity consumption is used for lighting purposes, so the LEDs contribute to saving the Earth's resources. Materials consumption is also diminished as LEDs last up to 100,000 hours, compared to 1,000 for incandescent lamps and 10,000 hours for fluorescent lights.
