It would be fair to say that many still believe or at one time thought that LED belysning was first discovered during the 1960s and by US researchers. But in reality, it was a British gentleman named Henry Round who - while working for Marconi Labs - had seen the first emission of light that came from a semiconductor diode a little more than a century ago.
The semiconductor LED is a crucial element for technology today. Countless households of our time contain small glowing indicators that were offered through LEDs and are being used for DVD and CD disks, computer games and drive, as well as for reading or transmitting alerts or signals to electronic devices from remote controls. Every day more and more vehicles are being outfitted with LED lys for brake lights and indicators. Perhaps what is most crucial is that LED is an essential connection between photonics and electronics. These are semiconductor lasers dependent on LEDs to send regulated optical signals inside the telecom fibers, providing for the continuously increasing demand for broadband telecommunication and internet.
Within the next decade the worth of the flourishing LED belysning market is estimated to surpass $15 billion annually. So does anyone in fact know who is responsible for inventing the LED and when? We do know that soon after the initial ruby laser was demonstrated, the semiconductor laser - which contains an LED at the core - was revealed not long after.
Going back again in history to 1962, there were four research teams in America that concurrently revealed an operating LED semiconductor laser that was structured on gallium arsenide crystals. Three papers had then been printed in the same volume of Applied Physics Letters. The persons associated were Nick Holonyak, Robert Hall and Marshall Nathan. These men's names now appropriately belong in the hall of fame for optoelectronics.
When it comes to the actual inventor of the LED itself, there is much less known about him. Sadly, the story of this man's life is actually quite tragic. Oleg Vladimirovich Losev was an incredibly gifted and young scientist that invested his employed life as a technician in various Soviet radio labs. Ultimately he would wind up dying from hunger at age 39 during the blockade of Leningrad during 1942. He had not received any formal schooling but in his short life he managed to publish 43 papers in leading British, German and Russian journals and receive 16 patents as the sole author. He would also go on to make huge breakthroughs in solid-state electronics - particularly the first solid-state semiconductor generator and amplifier, the crystadine. During 1924 the Wireless World and Radio Review publication composed that Losev had achieved global fame in association with his discoveries. Unfortunately his work has been generally misplaced by the broader research society.
With many thanks to every contributing analyst and scientist of the day, led lys have gone under great innovation to become efficient, cost-effective accessories and equipment in the categories of high-powered, LED downlights and miniatures. If not for those who sacrificed their time and lives for such worthy inventions like LED, we should shudder at the thought of how technologically far behind we could be.
