The Nobel Prize in Physics awarded to inventors LED bulb


Isamu Akasaki Japanese, Hiroshi Amano and American Shuji Nakamura was spent for “inventing a new source of light and energy efficient a good perspective for the environment.”

The Nobel Prize in Physics was awarded to Japanese Isamu Akasaki Tuesday, Hiroshi Amano and American Shuji Nakamura, inventor of the light emitting diode (LED). These researchers are devoted “to have invented a new source of light energy efficient and good for the environment point of view,” said the Royal Swedish Academy of Sciences said in a statement.

“With the advent of LED bulbs, we now have more lasting and more efficient light sources to older alternatives.┬áSince about a quarter of the electricity consumption in the world is used for the purpose of lighting, LEDs help save the Earth’s resources, “said she further stated.

By creating blue LEDs in the early 1990s, Isamu Akasaki, born in 1929, and Hiroshi Amano, born in 1960, both professors at the University of Nagoya, and Shuji Nakamura, born 1954 and a professor at the University of California at Santa Barbara, have “succeeded where everyone else failed.”

The red and green LEDs had existed for fifty years, but it adds a blue light, it was not possible to create white light.

“Only the triad of red, green and blue that can produce white light that enlightens us,” said the Academy, thus evoking a “revolutionary invention”.

“Incandescent light bulbs illuminated the twentieth century, this century will be lit by LED lights,” said the committee. The three winners will receive their prizes in Stockholm on Dec. 10. They will share Rs.6,83,16,485. (Approx 6.83 Crore)
