From power to light: How LED works

An incandescent lamp lights up because a filament is heated by electrical energy. An LED bulb lights up because electrical energy is directly converted into light energy. Therefore, LED bulbs don’t get nearly as hot as incandescent bulbs. LED means Light Emitting Diode. An LED is a semiconductor. In fact, a diode is the simplest form of a semiconductor.

Semiconductors are a special material that is contaminated so that one side is negatively charged and the other is positively charged. Or put another way: one side has an excess of electrons, while the other side has holes in which the extra electrons can fall. In the LED, the semiconductor is made of a special material - typically gallium arsenide - that releases particles called photons, when the electrons fall into a hole. When you power an LED, the electrons move, falling into the holes and emitting light. Depending on the production technology used and the semiconductor materials, LEDs can emit light in many different colors: red, green, yellow, orange, and blue.

LED lights in all colors

There is a reason why the first LED lights were red. Because the easier the electrons fall into the holes, the lower the frequency, and red light has the lowest frequency of all visible light. It is much harder to make blue light with LEDs because blue light has a high frequency.

LEDs only emit light with one specific frequency, so how is it possible to make white light with LEDs? To achieve this, it’s necessary to put blue, green, and red LEDs together so that the mixed light turns white. Or you can lubricate a blue LED with a phosphorescent material. When the blue light hits the material, it emits yellow light. Blue light with a yellow light gives white light.

The history of the LED

The LED is not a new invention. As early as the beginning of the 20th century, the English experimental physicist HJ Round worked at Marconi Labs with light-emitting semiconductor materials, and around 1924-26, the Russian Oleg Vladimirovich Losev succeeded in developing the first LED. It was not until 1965 that the first LED was developed for mass production. It emitted visible, red light and was developed by Nick Holonyak Jr. at General Electric. Nick Holonyak is today considered the "father" of LEDs. In terms of lighting, however, the breakthrough came when the Japanese Shuji Nakamura developed an LED that emitted something reminiscent of white light. It came on the market in 1993.

Since the 1960s, LEDs have become more and more efficient, and historically, every three years, the light output of the same electric current through the diode has doubled. The result is that the diodes today shine brightly enough that they can be used as light sources in many different types of lamps. A particularly advantageous relationship between energy consumption and light output means that there is great political and industrial interest in using LEDs as light sources. Currently, LEDs are 5-6 times as energy-efficient as ordinary incandescent lamps and thus on a par with energy-saving bulbs - the so-called A-bulbs. Today, LED bulbs are used in a wide variety of different forms of lighting and are available both for decorative lighting and for lighting indoors as well as outdoors.
