Over the course of the past 30 to 40 years, Light Emitting diodes (LED) have been used for a wide range of applications. As the technology has developed, the use of LEDs in homes, such as in LED downlights, and commercial locations, in fixtures such as LED panels, has increased.
From Silicon Carbide to LED Panels| The History Of LED Lighting
Although the use of LEDs has been common for just a few decades, and use in the home is an even more recent development, the history of LED lighting actually dates back over 100 years. The technology has been evolving much quicker recently, leading to the development of LED panels, downlights, cabinet lights and many other forms which are available here at Lyon Lighting. Here’s a quick look back at how the story began.
1907 – Englishman Henry Joseph Round discovered that inorganic materials can light up when an electric current is applied. He published this observation of electroluminescence, which was discovered using silicon carbide and a cat’s whisker, in the journal ‘Electrical World’. This was the first known report of such an affect.
1920s – Russian radio technician Oleg Losev independently discovered the same phenomenon when he noticed diodes in radio receivers emitted light when an electric current passed through them. He published the details of his discovery in Russian, German and British journals and a total of 16 papers were published between 1924 and 1930. He wrote to Albert Einstein asking for help on developing the theory but received no reply.
1960s – In 1961, Bob Biard and Gary Pittman developed the first modern LED, the Infrared LED, at Texas Instruments. The discovery was a happy accident which occurred while Texas Instruments tried and failed to make a laser diode. The discovery was made when testing a tunnel diode using a zinc diffused area of a Gallium Arsenide semi-insulating substrate. Just a year later in 1962, Nick Holonyack Jr developed the red LED, which was the first visible LED light.
1970s – A decade after Holonyack Jr created the red LED George Craford not only developed a brighter version of the red LED, but also created the first yellow LED. In the same year, Herbert Maruska and Jacques Pankove created the violet LED, which was the foundation for Shuji Nakamura’s bright blue LED which he developed in 1979.
1990s – In 1993, Nakamura commercialised his bright blue LED. His development of the blue and ultra violet LEDs led to the creation of the first white LED in 1995.
The full potential of LEDs is still not known, and since the creation of the first white LED technologies have developed to create more powerful LEDs with lower production costs. LED panels, downlights and other solutions are now more cost-efficient as a result.
