Where Did LED Technology Come From?

It’s reported that Russian and German scientists revisited the idea of light produced this way Nearly 20 years later. The light was still of such poor luminance that the idea nearly died again. The science of electroluminescence languished in obscurity for a while. It didn’t begin to gain favor again in the 1950s until some British scientists started experimenting with it again. This led to the first infrared LED. From this technology came the first visible spectrum LED, in red, from GaP.

It was been as the start of the LED revolution. From that point each decade brought advances in LED technology. The use of different substrates brought brighter lights of different colors. The colors advanced from red to commercial carpet cleaner and on to pale green, then yellow and on to a brighter green. By the 1990s the use of GaN helped usher in the era of blue LEDs. These blue lights became the basis for white light. The use of fluorescent phosphors helped change that blue light into high intensity white lights. Now LEDs can be found in almost every visible color of light.

This technology has led to additional uses for the LED as well. Due to their low light output they started out in indicator lights and display light applications carpet steam cleaner. Therefore, they were used only in expensive laboratory and test equipment. They later began to be used in appliances, calculators and watches.

As the LED technology advanced and the luminescence increased, the uses for LEDs increased. In 1977, the first LED flat panel television prototype was produced. This prototype was a red, monochromatic display. Later, in the 1990s, low-cost, efficient blue LEDs emerged carpet upholstery cleaning this use along. Once a full spectrum of colors was realized in the late 1990s the flat panel LED television became a fully functional and popular option.

LEDs began popping up in devices used to illuminate areas. Flashlights, landscape lighting, and other lighting sources became popular. Emergency lights began to use this technology. Traffic lights upholstery stain removal replaced with LEDs. Interior lighting and headlights in vehicles became a common home for these lights, as well. As the cost of producing the lights decreased, and the availability of colors and brightness increased, the uses exploded.

In a word, From an accidental discovery to a common household name, the history of LEDs is a long one. The LED certainly earned its prominent spot in today’s society.
