LED 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 device in your hand. So let’s explore it:
