The 2014 Nobel Prize in Physics was awarded to three Japanese scientists for their discovery and development of energy efficient blue light emitting diodes (LED.

According to the Royal Academy of Sciences, the award of 8 million krona or US $1.1 million will be shared among Shuji Nakamura, from the University of California and Isamu Akasaki along with Hiroshi Amano, from Meijo and Nagoya Universities.

Their ingenious invention is praised for its usefulness. According to Nobel committe chairman Per Delsing from Chalmers University of Technology in Gothenburg, this successful attempt at blue LEDs has eluded many big companies but in the end, these scientists prevailed.

Although this development of blue light emitting diodes has been around for only 20 years, the Royal Academy of Sciences recognize this invention has proven to generate white light in a more energy efficient manner that poses energy saving benefits.

Around one fourth of the world's electricity is used for lighting and the advent of LEDs can benefit global energy consumption by reducing electricity use and saving resources in the process.

The Nobel Foundation was founded in 1900 and was named after Alfred Nobel, the inventor of dynamite, who hails from Sweden.

Yearly prizes are given to individuals for achievements in chemistry, medicine, physics, literature and peace. The very first Nobel Prize in Physics was awarded to Wilhelm Roentgen for discovering X-rays.

Last year's winners in physics were Peter Higgs and Francois Englert, who discovered the Higgs boson particle that explains how mass exists in the universe.
