LED lighting seems like it has been around for a long, long time by now. Energy efficient lighting has come a long way from the first LEDs being used commercially in everyday household items such as TVs, calculators and radios. But how exactly did the LED lighting technologybecome so efficient, and more importantly how exactly was it discovered?
Fortunately enough the inventors of the blue LED light have been honoured by winning the Nobel Prize in Physics; professors Isamu Akasaki and Hiroshi Amano from the University of Nagoya and professor Shuji Nakamura of the University of California.
Why specifically the inventors of the BLUE light-emitting diode?
Originally LED lights could only be used in red and green formats which we saw in our household items (or more excitingly holiday season lighting). After many considerable attempts in both commercial and scientific to create a bright LED light no one was able to do so until these three researchers created technology which found the solution. Below is a brief overview of how it works:
Their invention helped create the white LED lamps which emit light common for our living and commercial spaces.
Why is this recognition significant?
Not only did they break through the colour spectrum, but they were able to create a long lasting and energy efficient alternative to common lighting technology. Currently majority of manufacturers and engineers keep working on improving the efficiency alongside lighting levels by advancing LED bulbs to suit commercial LED lighting solutions including high-bay applications and outdoor places. It opened up a whole new world of everyday energy efficient lighting which was previously not possible.
Take the time to appreciate this recognition, including all of the positive outcomes as a result of these individual’s research.
