What Is LED Light and What is LED full form?

What Is LED – 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.

What is the Principle Of LED

In today’s article, we will tell you what is LED (LED) related to electricity, which 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, when, and what its history is, if not then we will tell you through this article what principle this LED bulb works?

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 bulbs, TV, computer, fridge, etc.

If you are interested in knowing all these things, please read this important article written by us till the end, because this article will be very important for you.

LED Information

After the discovery of electricity, the discovery of the LED bulb is by far the most important, 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.

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 with very less electricity.

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

LED Full Form

“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 colors, red to blue (with a wavelength of 700 nanometers) and blue to purple (with a wavelength of 400 nanometers).

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

How LED Light Work – What is the Principle Of LED

Principle Rule Of LED – On passing a current through the diode, minority charge carriers and majority charge carriers recombine at the junction. On recombination, energy is released in the form of photons.

What is the Principle Of LED

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.

How do LED Dimmers work?

The LED simply creates a dimming effect using either pulse width modulation or analog dimming. With the first option, the fixture essentially creates a pulsing of light levels which are in essence flickering between high and low (or bright and dim) and are rapidly fired off in millisecond successions.

The lights cycle on and off so rapidly that it is undetectable.

Since the human eye only perceives the light tone and not the flicker, it achieves a dimming appearance even though the actual light output remains the same.

The second option of analog dimming relies on the actual reduction of the current flow to create the dimming effect. However, with this method, the quality of the light is diminished so it is less effective than the pulse width modulation method.

Which LED lights are the best?

If you are bay a LED lights then, first of all, you can check the symbol of the company and choose your best company for reviews.

  • Philips.
  • Osram.
  • Havells.
  • Wipro.
  • Bajaj.
  • Eveready.
  • SYSKA.
  • Oreva.

Which LED light color is best for sleep?

Red light is by far the best calming light color for sleep. Choosing a red light as a nightlight ensures that you don’t disrupt your circadian rhythm. So switching to a red light a few hours before going to bed will surely help you fall asleep easier.

What is the market price of LED bulbs?

Many companies are 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 based on 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, and Oleg Losev.

The process of making an LED bulb started from the year 1927, and 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, it which produces more light in less electricity consumption.

Nick Holonyak is the father of LED and is called the father of the 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 Crawford was a student of Nick Holonik when he invented the yellow LED the 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 them, 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, the 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 nanoseconds 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 things that have benefits, 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.
