Have You Ever Wondered What An LED is?

February 28, 2022

You are on our website, so you have an interest in digital LED signage. You must have thought, “I wonder what an LED is?”

L.E.D. is an acronym for “light-emitting diode” but what is a diode? A diode is an actual semiconductor, made out of one of about 4 or 5 elements. Yes, an element like you talked about in high school chemistry. Most diodes are made from silicon, others are made from gallium, arsenide, or germanium. If we pass an electric current through the diode, the diode glows so brightly we can see it at a distance. We can make diodes very small or large and in a variety of colors. We can organize them in such a way, give them quality power supply, control them with a computer, and make fabulous digital displays with diodes.

LEDs are energy-efficient; they don’t require a lot of electricity to make them illuminate. They are also fairly cheap to make. Best of all, they are environmentally-friendly to produce and use. Diodes convert 95% of the energy they are given directly into light and diodes last a long time, ten or eleven years.

LED technology is really cool. Call us today and we can discuss your sign ideas and help you design a sign to get your message out.
