the light bulb: past, present and future

We all need light to thrive.
Using our natural light sources, the sun, and even artificial light, light up both what we do and all the activities we do.
It is very important that without light, it is difficult or even impossible for the Earth to sustain any form of life.
All the biological activities in our bodies, and the activities around us, flourish in the light.
Light bulbs are considered one of the greatest inventions of human beings.
It has been evolving since its discovery in the 19th century.
Edison is the inventor of incandescent lamps.
But before him, many scientists discovered the light bulb.
Scientists have found that a thin metal strip glows when heated for a long time.
But efficiency is a huge problem.
Humphrey David first proposed the invention in 1802 and raised eyebrows from many other scientists at the time.
The only problem with incandescent lamps at the time was the material that produced light.
For the first time, it was discovered that platinum bars were the only material that could hold light for any period of time.
But the atmosphere does not allow long periods of light.
So they decided to make a fully covered, air-tight bulb.
Edison uses the carbon wire and the sealed bulb, which is longer than the light emitted using the original platinum wire.
Scientists agree that Edison\'s invention is incredible and sustainable, so he is called the father of electricity \".
With the progress of lighting technology, CFL bulbs came into being.
Compact fluorescent lamps are smaller in size and longer in duration compared to incandescent lamps.
The materials used in the CFL bulb are gas and magnetic.
Magnetic materials are used to initiate the movement of elements in gases that emit light.
Fluorescent bulbs use mercury, a toxin that is toxic to humans and can become very dangerous if it breaks down and is difficult to handle.
These bulbs produce less heat and are therefore more efficient.
They also produce more light than incandescent lamps.
The heat generated by incandescent lamps will eventually consume more energy.
Before replacement is required, the life of the CFL bulb can last between 6,000 and 13,000 hours, where the life of the incandescent lamp ranges from 750 to 1,000 hours.
The invention of advanced LED (
LEDs)
Light bulbs have a great impact on the market in all aspects.
The light emitted by a single diode is very small, so most of the time there will be multiple diodes in the bulb that can glow continuously, even if one of the diodes goes out.
The LED bulb can run for 22,000 to 25,000 hours.
Some LED bulbs even have a lifetime warranty.
Another important thing to keep in mind about LED lights is that most bulbs do not glow in all directions, so they are specifically designed for one-way lighting.
But with the further development of LED technology,
Directional lights are being sold on the market.
LED bulbs are widely used for indoor and outdoor lighting.
