LED Light Bulbs: How do Light Emitting Diodes Work?
LED light bulbs are set up much differently than traditional light bulbs. For that reason, they have some electrical components that are different from incandescent light bulbs. Unlike incandescent lights that emit light from a vacuum, LED bulbs emit light from solid matter, known as a semi-conductor.
Consider a semi-conductor like a sponge cake, with different layers that allow electrons to move around through the holes of the cake. The bottom layer, filled with negatively charged particles, move throughout the semi-conductor once it is powered and activated. The top layer, filled with positively charged particles, move through the conductor at the same time. Both the positive and negative charges meet together in the middle layer, where light is emitted from.

LED Vs. Incandescent
Unlike incandescent lights that emit light from a vacuum, LED bulbs emit light from solid matter, also known as a Semi Conductor.
What Is A Semi-Conductor?
Think of a semi-conductor like a sponge cake, with three layers that allow the protons and electrons to move around through the holes. A Semi-conductor contains layers of negative and positive magnetic charges.
The bottom layer is the negative layer, the middle layer is the active layer, and the top is the positive layer. When the semi-conductor is struck, the flow of electrons is activated and moves from the negative layer to the positive layer. As the electrons are activated, they emit light.
