LED reklam is a tiny light source that twinkles in many applications that surround you. You have probably seen it around your Christmas tree, in digital clocks, the flashlight of your Smartphone or the lights in your luxurious swimming pool. This easy to use and commonly available light source looks usual but has some solid physics behind its radiance.
Knowing the science behind this cool light will surely result in stepping-up your knowledge when you again hold an LED reklam device in your hand. So let's explore it:
What is LED reklam ?
LED is actually an acronym for 'Light Emitting Diode', which uses 'Solid State Lighting' technology to emit monochromatic light.
For those who are novices to physics, 'Diode' is a two terminal electronic component made from semiconductor material. This solid matter inside the diode when energized, starts to emit light and so the technology is called solid state lighting.
History behind LED
The revolution of LED reklam light is originated by the discovery of the phenomenon termed 'Electroluminescence' in 1907. Technically it's a basic working principle of LED. Infrared is observed as the first light emitted from diode. The first color visible through LED was red and was developed by Nick Holonyak in 1962. Thus, he is also considered the "Father of LED". From then till today, the discovery of various semiconductor materials and invention of several technologies makes LED reklam emit a spectrum of light through it.
What is LED light technology?
LED reklam technology is completely based upon the semiconductors electronic theory. So to understand it completely, one requires in-depth knowledge of semiconductor physics. In a simpler way it can be explained as-
