We are going to try explain in a good easy way.

How does LED work?
You have probably heard before what a LED is, or a little history about them. The many uses LED tech has but, do you know how they work?
The basics of LED tech is based in the diode, an electronic component with two points that allows the energy circulation through itself in one way. This is the energy delivery through the conductive materials.
To create the LED diode, two regions are unified: N & P. In the region joint a potential barrier is formed which function is to deny the electrons way from N to P when they are not correctly polarized and electrons don’t possess energy enough to go through it.
When we apply tension that allows straight polarization to a LED’s ends, electrons that come from the power source start flowing. Every time there is an electron with excessive negative charge present in region N, it gets energy to be able to win over the resistance that the barrier is creating, then it goes through and gets combined with a positive whole in excess in region P. In that same instant, excess energy that acquired the electron to be able to change region it’s transformed into electromagnetic energy that is liberated into light photons.
What do we find inside a LED?
The most important to know about the insights of a LED, is that closed up in a little capsule in a clear color (it can also be dark) you can find the semiconductor chip. The chip structure in LED diodes uses a material combination that are good conductors and possess the property of emitting light photons when it’s run through an electric current.
