LED is a type of electronic device that emits light when electrical current is passed through it. The LED has a full-form ” Light-Emitting Diode .”

Earlier LEDs used to produce only red light, but nowadays modern LEDs are capable of producing almost all colors, including red, green, and blue (RGB) light. At the same time, due to the recent advances in LED technology, it was possible for LEDs that they are now able to produce white light as well.

LEDs are very commonly used in indicator lights (such as power on / off lights) in electronic devices. They also have many different applications, including electronic signs, clock displays, and flashlights.

Since LEDs are very energy-efficient and have long lifespan (which is about 100,000 hours), they are used in many places instead of traditional light bulbs. For example, street lights, red lights of cars, and many types of decorative lighting. If you want, you can identify LEDs which often have many small lights in the series, which together make a big display.

Due to the energy-efficient nature of these LEDs, they use very less energy as compared to other bulbs, while their light is also much brighter. This is the reason why the traditional flat-screen LCD displays have been replaced and now LED displays are being used in their place, in which LEDs are used on the backlight. LED TVs and computer monitors are typically brighter and thinner in size compared to their LCD counterparts.
