History Of LED Lighting Products
The LED (light-emitting diode) has a very long history. It dates back to 1907 and continues to evolve. It has taken years to perfect design and make LED lighting products available in various forms, making it easy for consumers to buy and use it in their home and business.
Electroluminescence was discovered in 1907 by a British experimenter and scientist, H.J Round. However, the discovery had no practical use for several decades. Another inventor named Oleg Vladimirovich Losev published an article on "Luminous carborundum detector (silicon carbide) and crystal detection" in the Russian journal Telegrafiya I Telefoniya bez Provodov (Wireless Telegraph and Telephony).
Losev's work was examined for several decades. In 1962, Nick Holonvak Jr. developed the first 'light-emitting diode', better known today as LED or LED. The first LED products were made available to the public in the late 1960s and lit a red light. They were mainly used as indicators on laboratory equipment and in place of incandescent indicators.
In 1968, gallium arsenide made LED much more affordable and accessible to the public. LED lighting products were always very expensive; it meant that not everyone could afford LEDs. It was later discovered that adding phosphorus would make it much cheaper and would still work in the same way as the materials previously used.
Over the years, LED lighting has become increasingly popular and more and more people have started to use it for other household devices such as electronic devices such as radio, television, telephone, calculators and even watches. LED technology was at its peak because it was the most innovative product on the market.
The first LED screen was developed by James. P. Mitchell in 1977. The first screen of LED television was presented at a technical exhibition in Anaheim on May 1978. This LED flat-screen TV received a special award from organizations such as NASA, General Motors and the University of California at Irvine, and a special mention was given by Robert M. Saunders, Professor of Engineering and President of the IEEE in 1977.
Effective and inexpensive blue LEDs did not appear until the early 1990s. It was at this time that the RGB color trihedron was completed. This has created new models, including new models for outdoor signage and large video screens for billboards and stadiums.
As LED materials technology became even more advanced, the light flow was increased and LEDs became bright enough to be used for lighting such as LED downlights, LED projectors, LED garden lamps, LED streetlights and many other forms of LED lighting.
Most LEDs were manufactured in the very common 5mm T1-3/4 and 3mm T1 cases, but as power increased as more and more needed, the cases needed to become more complex to dissipate heat. Today, high-powered LED lighting products look little like the old LEDs.
