Creating a light bulb

Creating a light bulb
It is very difficult for a modern person to imagine that such a familiar and inseparable thing as an electric light bulb began to take its first steps a hundred years ago. Most modern devices are mostly limited to one or two inventors. But there are also very interesting exceptions, one of the most striking examples of such an exception is an incandescent lamp.
It's hard to believe, but a simple light bulb was made not by one, not two or three, but by 13 scientists. And there is a simple explanation for this: the fact is that between the first incandescent lamp and the lamp we use now, there are about 100 years of constant work, which was carried out by scientists from many countries. Each of these people made a huge contribution to the invention of the light bulb, so it is, alas, impossible to unequivocally name the inventor. The beginning was laid by the research of the scientist Vasily Petrov, who observed the voltaic arc.
Later, the same discovery was made by the British Devi. Both noticed that the voltaic arc was suitable for lighting. But it was necessary to choose a more suitable material for the electrodes, since the carbon rods burned out in a couple of minutes and were unusable. In the 19th century, two types of electric lamps became common: arc lamps and incandescent lamps.
Arc lamps appeared much earlier. Their action is based on a voltaic arc. In 1875, Pavel Yablochkov came up with a simple and, most importantly, very reliable solution for arc lamps. He separated the carbon electrodes with a protective layer and placed them in parallel. In 1877, thanks to this, street lighting was first organized. Under the name "Russian light," Yablochkov's lamps were used for lighting in various cities around the world. A little later, engineer Alexander Lodygin invented the "filament lamp". As a thread, he used a carbon rod placed in a vacuum vessel. The great breakthrough in the improvement of the light bulb was made by the American Edison.
He calculated detailed diagrams of power plants and communications to factories and homes. I calculated the cost of materials and calculated that the cost of a light bulb for a consumer should not exceed 40 cents. Since 1877, he has conducted more than 12 thousand experiments. His assistants tested about 5,000 different compounds and substances, while spending more than 100,000 dollars. The electricity usage fee was hourly. But this reduced the number of connections, and people actively conducted electricity to their homes.
The final step in improving the light bulb was the use of noble inert gases to fill the lamp. Thanks to this idea by Irving Langmuir, modern light bulbs have become brighter and more durable. Now science is making such an important and irreplaceable device as a light bulb even more efficient and simpler, but the names of those who worked on its creation in the past will forever remain in the history of world science.
