Li-Fi crucial to the future of lighting, says LED inventor

Shuji Nakamura, the man who won the Nobel Prize for inventing the blue LED, has named Li-Fi as crucial to the future of lighting technology.


Speaking at Academia Sinica, in Taipei, Dr. Nakamura stated that LED has now reached a ‘stage of maturity’ and manufacturers are seeking out new markets where they can thrive into the future.

Nakamura named Li-Fi and laser lighting as two crucial areas the LED industry needs to concentrate on in order to further their businesses successfully.

The Nobel Laureate also stated in his lecture that there has been areas in which the advancement of LED has surpassed even his expectations.

For example, researchers in Taipei have recently begun using LEDs to separate malignant cancer cells from normal cells.

Most recently, Nakamura has been dedicating his time to developing laser lighting, which he hopes, will one day replace LED.

Laser lighting has already been used successfully in car development. Automotive headlights that feature laser lighting are able to project light as far as 600 metres, which is much longer than the 300 metres managed by LED.

Nakamura predicted that should Li-Fi and laser lighting combine, then the Li-Fi technology would be able to transfer data at speeds up to one hundred times faster than Wi-Fi can currently manage.

However, laser lighting does not currently have the same efficiency benefits as LED and is, in comparison with LED, quite expensive, costing up to ten times more than its sister technology.

Nakamura is currently teaching at the University of California in Santa Barbara, with his two fellow researchers, Isamu Akasaki and Hiroshi Amano, who together received the Nobel Prize in Physics in 2014 for ‘developing the manufacturing technology of the blue LED and fostering the emergence of bright, power-saving white LED.’
