What is LED and What is its full form?



Talking about LED, Its full name in English is Light Emitting Diode. It is a device that emits light when an electric current is passed. It is a semiconductor device.

In today’s article, we will tell you about what is LED (LED) related to electricity, that is, the most used source of light in today’s time.

So have you ever wondered, how would this LED bulb work, who discovered it and when, what is its history, if not then we will tell you through this article on what principle this LED bulb works. Is.

We all use many such things in our daily life, which are powered by electricity. We use most of the electrical items in our daily routine, such as bulb, TV, computer, fridge etc.

If you are interested to know all these things, then please read this important article written by us till the end, because this article is going to be very important for you.

LED Information

After the discovery of electricity, the discovery of the LED bulb is by far the most important and important discovery, because it is a technology through which light is emitted. When electricity is passed through the LED bulb.

So light is produced in it only when all the elements present inside it (electrons and other gases) are mixed with each other.

This device is made up of light solid semiconductor material.

This is the reason why this device is also called a solid device.

As we all know that LED is the most important and necessary invention of this war, because this device is used in a very large amount in today’s time.

It is being used the most because very small LEDs are used to make a bulb and it produces more light in very less electricity.

Its most important thing is, if we connect the anode cathode located in it with any voltage, then it can generate light of different colors in the right amount.

Full Name of LED

“The full name of LED is Light Emitting Diode.”

The light that is produced when the LED is lit is of a straight wavelength.

It generates its light through three colours, from red to blue (with a wavelength of 700 nanometers) and from blue to purple (with a wavelength of 400 nanometers).

Some LED bulbs also emit infrared energy, that is why they are also called IRED (infrared emitting diode).

On what principle does the LED bulb work?

The substances used in LED bulbs are generally aluminum, gallium and arsenide. It is in its original state itself, with all the atoms of this substance closely intertwined.

This bulb works on this principle and as soon as electricity is passed in it, this bulb starts producing light.

What is the market price of LED bulb?

There are many companies making LED bulbs across the country, each company determines the price of its bulb based on the materials used in its bulbs.

The price of the bulb made in the companies is kept according to their electricity consumption and also according to the light. The market price of the bulb starts from ₹ 100 and is also sold for very high prices.

Their prices are also determined on the basis of their size.

Some companies making LED bulbs

There are many companies manufacturing LED bulbs all over the world, out of which the names of some very developed ie considered companies are mentioned below.

We have the most developed and best LED companies in India like Surya, RK Light, Bajaj etc. LED bulbs of foreign companies are also sold in India, which is very valid ie

The bulbs of these companies are considered very good.

Who invented the LED bulb and when?

The LED bulb was invented together by these scientists, the names of these scientists are Shuji Nakamura, Nick Holonik, Oleg Losev.

The process of making LED bulb had started from the year 1927, success in making this bulb was achieved in the year 1968.

As we all know, the bulb was first invented by Thomas Alva Edison in 1879, but the bulb made by him used to consume a lot of electricity.

Therefore, if these scientists invented the LED bulb on the same principles as Sun, which produces more light in less electricity consumption.

Nick Holonyak is the father of LED is called the father of LED bulb.

A short history related to the invention of the bulb

As we told you above that the bulb was invented by Thomas Alva Edison in 1879 in America.

For this Thomas Alva Edison was controlled by the President of America in the White House and he was also honored. The bulb made by Edison needed a lot of electricity.

That’s why three scientists invented the LED bulb, which requires very little electricity.

George Crawford invented the yellow LED in 1972. George Craford was a student of Nick Holonik, when he invented the yellow LED bulb, he achieved a lot at that time.

Some important information about Thomas Alva Edison

Thomas Alva Edison was born on 11 February 1847 in Milan, a small town in America. He was a little crazy in his childhood, that’s why the people there used to make fun of him by calling him crazy.

Thomas Alva Edison was very fond of experimenting. He wanted to prove any of his work by experiments only.

A letter was written by the principal of his school to his mother, in which it was written by the principal that Thomas Alva Edison is insane and he cannot be taught in that school, because he used to disturb everyone, that’s why you can take him at home Teach it.

Once Thomas Alva Edison went to the chicken farm with his mother, there he saw a hen sitting on the egg and small chicks came out of that egg.

After going home, he took a dozen eggs and sat on it, the chicks did not come out of it, but the eggs broke and their paint got spoiled. For this he was also scolded by his mother.

Advantages of LED Bulbs

As we all know, LED bulb is very useful and beneficial in our daily life.

We get many types of benefits from LED bulbs, such as; It generates more light with less power consumption. The LED bulb does not emit any kind of heat.

Its overall output power is less than 150 milliwatts, due to which the news of power is very less. It is very fast, that is, within 10 nano seconds of passing electricity in it, it starts generating light here.

A good LED has a lifespan of up to 20 years. It is connected to many types of circuits, so that the power shortage here can be easily tolerated.

Disadvantages of LED Bulbs

We all know that the things which have benefits, they must have some disadvantages, so in such a situation, the disadvantages of LED bulbs have been told below.

If there is an excess of electricity in this bulb, then this force gets spoiled very soon. This LED bulb depends on the outside temperature, ie it depends on the wavelength.

Conclusion

Today we all know how important light is for us. Be it night or day, you definitely do light up inside the house. For which different types of bulbs are used.

In this article it was told that what is LED and who invented it, by whom its principle was propounded, who is called the father of LED bulb.

We hope that you must have liked this article, so please do share it with your friends.
