What is LED?

Definition – What does LED mean?

Light-Emitting Diode (LED) is a commonly used electronic device that emits light when electrical current is passed through it. Early LEDs only produced light, but the advanced LEDs can produce multiple different colors such as red, green, and blue light. Recent advances in light-emitting diode technology have made it possible to produce white light as well.

Glossary Web explains LED

Light-Emitting Diodes are most commonly used for indicator lights on different kinds of electronic devices. They also have multiple other applications, including clock displays, flashlights, and electronic signs. Since these devices are energy efficient and have a long lifespan, they have begun to replace old-style bulbs in multiple areas. Most common examples include street lights, various types of decorative lighting and red lights on cars, etc. You can usually identify LEDs by a series of small lights that make a larger display.

The energy-efficient nature of Light-Emitting Diodes enables them to produce brighter light as compared to the other types of lights bulbs while using less energy. For this, traditional flat LCD displays have ongoing to be replaced by LED displays that use LEDs for the backlight. LED TVs are normally brighter and thinner than their LCD counterparts.
