What Is The Full Form Of LED

LED stands for “Light Emitting Diode”.

In the simplest terms, a Light Emitting Diode (LED) is a semiconductor device that emits light when an electric current is passed through it. Light is generated when the particles (known as electrons and holes) are combined together within the semiconductor material.

Since light is produced within the solid semiconductor material, LEDs are described as solid-state devices. The term solid-state lighting, which also includes (OLED).

The light-emitting diode is a semiconductor device. It is a PN junction that emits or produces light when passing through an electric current. LED lighting can be more versatile, efficient, and long-lasting than compact fluorescent lighting.

This type of diode emits narrow bandwidths of visible light or invisible light at different color wavelengths for remote control. It is better because it is smaller in size and has many optical components to shape its radiation pattern.

Before going into how LED works, let’s first take a brief look at the light. Since ancient times man has received light from various sources like sunlight, candles, and lamps.

In 1879, Thomas Edison invented the incandescent light bulb. In the light bulb, an electric current is passed through a filament inside the bulb.
When sufficient current is passed through the filament, it becomes hot and emits light.

Unlike light bulbs in which electrical energy is first converted to heat energy, electric energy can also be directly converted to light energy.

How Does LED Work?

In Light Emitting Diodes (LED), the electrical energy flowing through it is directly converted into light energy.

Light is a type of energy that can be released by an atom. Light is made up of many small particles called photons. Photons have energy and momentum but no mass.

Atoms are the basic building blocks of materials. Every object in the universe is made up of atoms. Atoms are made up of small particles such as electrons, protons, and neutrons.

Electrons are negatively charged, protons are positively charged, and neutrons have no charge.

Quick Tip: Why not make some quick cash doing small tasks on your smartphone.

The attractive force between the proton and the neutron makes them stick together to form the nucleus. Neutrons have no charge. Therefore, the overall charge of the nucleus is positive.

Negatively charged electrons always revolve around a positively charged nucleus because there is an electrostatic force of attraction between them. Electrons move in various orbits or shells around the nucleus. The energy level of each orbit is different.

For example, electrons orbiting very close to the nucleus have low energy while electrons orbiting far from the nucleus have high energy.

Low energy level electrons require some extra energy to jump to higher energy levels. This additional energy can be supplied by an external source.

When the electrons orbiting the nucleus receive energy from an external source, they jump to a higher orbit or higher energy level. Electrons do not last long at higher energy levels. After a short period, the electrons fall back to the low energy level.

Electrons that jump from higher energy level to lower energy level release energy in the form of a photon of light. In some materials, this energy loss is mostly released as heat. The electron that loses more energy releases more energy photons.
