slide 2:

What is an LED LED stands for Light Emitting Diode a semiconductor device that converts electricity into light.

slide 3:

LED: How It Works

slide 4:

If current flows through a diode negative electrons pass one way and positive holes move the other way.

slide 5:

The holes exist at a lower energy level than the free electrons therefore when a free electron falls it wastes energy.

slide 6:

This energy is emitted in a form of a photon which causes light.
