Hello and welcome to our tutorial where we a look at all things LED. Now first of all, what is an LED? LED stands for Light Emitting Diode and is an electronic component used to convert electrical energy to light energy. This process is called electroluminescence. LED technology is all around us, indicators on consumer electronics, automotive brake lights, TV screens, almost every electronic product will utilise LEDs in some way shape or form. The widespread usage of LED technology is due to the power efficiency, compact form, robustness, and ease of use compared to traditional forms of lighting. So now that we know they’re useful, how do they actually work?

In this article, we’ll be using basic electronics theory and terms, so if you’re not familiar with Ohms law, voltage, current, and other such terms, take a quick read of our Analogue Electronics Crash Course first.
