What is the full form of LED?

LED Full Form – Light Emitting Diode

LED is an abbreviation for Light Emitting Diode. LED is a semiconductor light source that emits lights when applying a predefined voltage. LED is used in electronic equipment today due to its very good quality.

Construction of LED

An LED is made by combining P-type and N-type semiconductor materials. Gallium arsenide (GaAs) or gallium arsenide phosphate(GaAsP) is used in the place of silicon and germanium. This material is utilized in LED because of its extraordinary qualities. This material has this property, and it emits light, not heat, when applying voltage.

When voltage is applied across the LED terminal, it releases energy in the form of photons(light). The color of the light depends on the bandgap of the semiconductor material used in LED.

For Eg: GaAsP LED emits red light, whereas InGaN LED emits blue light.

The LED is manufactured as a forward bias device.

Principle and working of LED

Driven is a semiconductor gadget that changes over electrical energy into light energy. LED works on the principle of electroluminescence. The property of semiconductor material that converts electrical energy into light energy is called electroluminescence. LED is a forward bias semiconductor device, which means it will start working when the P terminal of the diode is connected to the positive potential of a battery and the N terminal of the device to the negative terminal of the storm. As said earlier, LED is a uni-directional device, meaning it will only allow current to flow in one direction.

When the LED is switched on, the electrons from the N side recombine with holes on the P side and release energy in the form of photons (light). The color of the light emitted by an LED depends on the materials used to make the LED. For example, red LED is made with GaAsP, and blue LED is made with InGaN. LED is a very efficient light source as it converts more than 90% of its electrical energy into light energy. Also, LED has a very long life span as it can last for up to 100,000 hours. LED is used in various applications such as indicator lights, traffic lights, flashed lights, etc.

Different colors of LED

were made available over time. The hardest thing to achieve was the white LED. Success was only gained a few years back, and since then, LED has become increasingly popular in home lighting.

Uses of LED

LEDs are used in many places, some of which are prominent examples. Tv backlighting, smartphone backlighting, LED display, automotive lighting, LED wallpaper, home lighting, and decoration are only a few LED uses.

The LED full form is Light Emitting Diode. LED is a two-lead semiconductor light source. It is used as an indicator in many electronic devices. The color of the light depends on the materials used to make the LED.

LEDs are used in various applications such as:

  • Indicator lights on electronic devices
  • Toys
  • Architectural and decorative lighting
  • Vehicle brake lights and turn signals
  • Emergency
Benefits of LED

LED has many advantages over old light, due to which LED has become so much more popular today. There are some major benefits are as follows:

– Energy Efficient: LED is the most energy-efficient light source that has been discovered so far. You can get a feeling of how energy productive the LED is from the old bulb, that a 9-watt LED gives more light than a 100 Watt old bulb. Today LED has become so energy efficient that 303 lumens of light can be obtained by spending one watt of electricity. Low energy consumption is also one of the reasons why LED TVs are replacing LCD TVs.

– Environment Friendly: Since LED uses less energy, it also helps in reducing greenhouse gas emissions.

This is because the power plants that generate electricity to power LED lights to produce less carbon dioxide than power plants that generate electricity to power old light sources.

– Long Life: LED has a long life compared to other light sources. The average life of an LED is about 50,000 hours, which means that if an LED is used for 8 hours every day, it can last for more than 17 years.

– Durable: LED is a very stable light source and can withstand rough handling. LED lights are often used in places with a risk of breakages, such as in traffic signals and flashlights.

– Robust: LED is a rich light source and can operate in a wide range of temperatures, from -40°C to 85°C.

– No Mercury: LED does not contain any mercury, which makes it a safer option than other light sources that do contain mercury.

– Instant On: LED lights up immediately when turned on, unlike old light sources that take a few seconds to reach their full brightness.
