LED Full Form | Light Emitting Diode

The LED full form is Light Emitting Diode. LED is a two-lead semiconductor light source. Light Emitting Diode is a PN-junction diode that emits light when it open.

It is a necessary electronic device because it consumes less electricity compared to others due to that most of the people use LED light nowadays.

LED is mostly used in electronic test equipment like TV, calculator, refrigerator, vehicles, watches, etc.

How LED works? 

When the stable voltage is passed through it, the electrons recombine with electrons holes and release the energy in the form of photons. This effect is known as electroluminescence. 

LED light color is determined by the energy bandgap of the semiconductor. 

LED light lamps are very energy efficient, economical, and long-lasting. If we compared to other bulbs it safe almost 80% energy.

History LED full form:

  • The phenomenon was discovered in 1907 by the British experimenter H.J Round of Maronic Labs with the help of a crystal of silicon carbide. 
  • First LED was created in the year 1927 by the Russian inventor Oley Losev. 
  • The first Blue-Violet LED was made at Stanford University in the year 1972 by Herb Maruska and Wally Rhines. 

Advantages of LED:

1) Energy Efficient:

  • LED required less energy compared to other lights.
  • light Emitting Diode does not produce heat.
  • It does not produce buzzing and flickering.

2) Environmental Friendly:

  • Light Emitting Diode is not toxic. LED does not contain mercury, lead, or calcium.

3) long life:

  • LED work can be work for a long time with fewer maintenance costs.

4) Maintenance and Safety:

  • It needs very little maintenance costs. 

5) Recyclable:

  • It is very easy to recycle. 

6) Color:

  • LEDs can emit different light colors without any color filter. 

7) Cool light

8) Slow failure 

9) Shock resistance 

10) Small size

Disadvantages:

  1. Temperature dependence
  2. Voltage sensitivity
  3. Color rendition
  4. Area light source
  5. Light pollution
  6. Use in water conditions
