We talked about what is LED technology, an led, a semiconductor device that converts electrical energy into light. If you don’t remember or did not follow our post of February, click here to see what he is formed. Today we will show how the LED arose and how you got to the current format, architecturally used.
In 1962, the researcher Nick Holonyak Jr. at GE, he developed the first LED capable of emitting a red light visible. Green and yellow LEDs took not to appear, and the technology was limited to these three colors for decades.
The LEDs were popularly known as on/off indicators in various electronic equipment, and computer cabinets. In the years 80, semiconductor technology allowed the LEDs they diminish, earning new formats and intensifying the brightness of light. At that time, began to be used in traffic lights.
The milestone in the applicability of the LED was only in 1993, when Japanese researchers Isamu Akazaki and Hiroshi Amano and the American scientist Shuji Nakamura invented the first high-brightness blue LED. The importance of this discovery is such that not only broke into the computer chassis, such as the creation of the white LED. From then on the LED was widely used in the automotive industry, used since the signalling lights Panel. In 2014, the trio gained recognition with the Nobel Prize in physics.
In the years 1997 and 1998 appear the first fixtures aimed at the architecture produced on a large scale: flags of floor and emergency lights. In 2000, Luxeon I revolutionized 25 LEDs lumens in a single issuer, brand never achieved before. The next eight years were marked by major advances and in 2008, the biggest fair of the world lighting, the Light & Building in Frankfurt, Germany, showed a great application of LEDs in various situations.
The use of LED today’s residential, commercial areas, lighting, decorative, complement and even in public lighting.
Evolution is such that the product has changed radically, and has a very different structure of LED used in electronic signal. Still hasn’t evolved as much as possible on LED system. LED technology still promises a solution each time more efficient, economical and sustainable.
