If you ask us, there’s nothing better than the holiday season. From homemade hot cocoa with marshmallows to singing carols and snowball fights, there’s no denying that it’s the most wonderful time of the year.

Read on to discover the definition behind LED and more.

What Is the Definition of LED?

According to the Collins English Dictionary, the acronym LED stands for “Light-Emitting Diode.” This refers to an electronic device that emits light when an electrical current (or voltage) is passed through it. Back in the day, LEDs produced only red light, but modern LEDs can produce a number of colors, including red, green, yellow, amber, blue, and white. 

Originally, LEDs were extremely costly and had little practical use. After being used in various electronics and laboratory test equipment, they made their way to household appliances like calculators, radios, watches, TVs, and telephones.

LEDs can also be used in applications such as fiber optics when manufactured with aluminum gallium arsenide (AIGaAs). Light-emitting diodes are also responsible for the backlighting of numerous LCD television sets.
