What is it made of?

  • Today’s LEDs have Indium tin oxide which makes the LED a lot brighter and last longer.

  • Indium tin oxide is transparent and colorless but when you put infrared light on it, it turns into a mirror of what color you are trying to get

  • This is one of the most used oxides because of all its properties and what it can do

  • http://en.wikipedia.org/wiki/Indium_tin_oxide


What s it made of cont

What’s it made of cont.

  • The main part of it is chips in it that shoot around electrons to different parts to emit light.

  • They started making LED’s around WW2 and kept on finding new technology.

  • Today’s LED’s are used in a lot of products because of how bright they are.

How does it work

How does it work?

  • LED’s don’t have a filament which means they wont burn out and they don’t get really hot.

  • They work mainly by the movement of electrons in a semiconductor

  • They last a very long time and go far past any other light bulb life

  • There are little chips in each one that throw around electrons that make light. They are replacing many light bulbs because of how well they work.
