LED lights can be found around our houses, in our toys, and in the streetlights around our towns. But what are LEDs? How do they work?

In modern houses, schools and workplaces, LED lights are used regularly. This is because they use much less energy – about one sixth – to make the same amount of light, since they don’t really get hot. LEDs can also last a very long time, compared to other lights. An LED light has a special material inside it called a “semiconductor” to produce the light.
