LED Lighting History, Why Is The Blue LED Special?

LED by Vision are proud to be a leading force in the UK community of LED lighting suppliers and designers. We appreciate the hard work, dedication and competence of all our global colleagues and inspirational figures. Here are three leading lights, please excuse the pun.

It began in the 1990’s

Blue LED’s were invented by Professors Isamu Akasaki, Hiroshi Amano and Shuji Nakamura and their subsequent award of the 2014 Nobel Prize for Physics attests to the value of their invention. It has been felt internationally.

The Nobel jury cited the invention’s inherent usefulness and agreed that Nobel winners were generally those who produced work that was of the “greatest benefit to mankind.”

Outperforming the big companies

You may take lighting solutions for granted but scientists appreciate that inventions take years of dedicated effort, trial and error and an iron will to succeed. The blue LED’s were an enduring and stubborn challenge for scientists in both academic and industrial settings.

The three scientists continued to test and research even as the big firms around them tried, failed and left the blue LED competition. That’s how they could achieve when the others couldn’t; their dedication was above that of corporate ventures.

Eventually, success beckoned.

Blue LED’s represent guaranteed excellent performance without any negative factors. Red and green LED’s have been in use for a while, so you may wonder why blue LED’s won such praise.

The Next Generation Of LED Lighting Solutions

Blue LED’s offer a new generation of energy efficient and low carbon footprint LED solutions including lightbulbs.

Without blue LED’s the LED based TV and computer screens wouldn’t mix three colours to produce white light. Blue lighting also encourages phosphorus to produce white light. Smartphones, lighting in mobile devices and throughout premises has been transformed by the arrival of blue LED’s. You have already absorbed some of its positive effects; research and development work continues in earnest.

20% of the world's electricity is used for lighting. Dr Frances Saunders, President of the Institute of Physics has surmised that this could be reduced to 4% with LED solutions.

The science behind the light

LED’s convert electricity directly into photons of light instead of the traditional bulb’s mixture of heat and light energy which is generated and wasteful. A current is applied to semiconductor materials in a LED which produces a defined wavelength of light. This wavelength depends on the chemical composition of materials.

The Nobel prize winning team used Gallium nitride to invent the blue LED’s. They grew large enough crystals on a scaffold, that was partly sapphire, to function efficiently. (This was the area that halted the progress of several rivals.) Later Professor Nakamura manipulated temperature to increase the growth of the crystals.

LED lighting suppliers like us know that blue LED’s have revolutionised the world, even if the majority of the population doesn’t realise it.

We’d like to help you to achieve greatness by reducing your energy consumption and bills with optimum LED solutions that embrace cutting edge technology.
