Ordinary incandescent bulb, which is used in almost every home, often referred to as the Edison bulb. The history of its invention was not so simple. Before giving artificial light to billions of people, it has come a long way of development.

Edison light Bulb

The American Thomas Alva Edison-one of the most enterprising people of this world. He owns about 4 thousand patents for various inventions. This man was the author of the phonograph, Telegraph, carbon microphone, peep show, the iron-Nickel battery and other devices. His name is associated with the idea of creating incandescent bulbs.

However, Edison bulb with carbon filament inside was not the first in the world. More than ten inventors worked on the problem of creating an artificial light source. There were lamps of different shapes and sizes, within which was located a bamboo, platinum and coal thread. Many of them were officially registered.

Why there are so many of the inventors of world fame only got Edison? Its main role lies not in the idea of creating lamps, and in developing ways to make the mechanism easy to use, cheap and accessible.

Edison bulb

First attempt

It is Difficult to exactly say who is the author of the idea to create the light bulb. But, before the light bulb Edison had conducted hundreds of experiments and the many similar inventions. First appear arc, and then incandescent bulbs. In the nineteenth century, the discovery of voltaic arc leads inventors to the idea of creating artificial light. This required to connect two wire connected to electricity, and then a little to alienate from each other. So between the wires, there is a glow.

There are certain information that the Belgian Gerard created the first lamp with carbon rod. The device is supplied current, and the rod produce light. Later it became known about the Englishman Delarue, which replaced coal platinum thread.

These bulbs was considered a valuable discovery, but their use was accompanied by great difficulties. Platinum filament was expensive, not everyone could afford to use this lamp. Carbon rod was much cheaper, but it is not long enough.

Edison light bulb story

Solid successes

In 1854 German watchmaker Heinrich Goebel creates a bulb with a thin carbon rod, which shines much longer than the previous one. To achieve this, the inventor succeeded with the help of vacuum. Lamp of göbel has long been unnoticed, and only years later it was declared the first light, fit for practical use (recognizing the Edison patent was invalid).

On improving the mechanism worked with Joseph Swan, Alexander Lodygin. Latest patented invention "thread lamp» working at the coal terminal in a vacuum. In 1875, a noticeable difference Pavel Yablochkov invented a “electric candles”. Russian engineer, used a filament made of kaolin, which is not needed in a vacuum. Lamp Yablochkov was used for street lighting and is widespread in Europe.

Improvement of the mechanism

The Main direction has long been known. Rod of a certain material is in a vacuum and is connected to the electric current. I only had to choose the correct material for the electrode for long lasting glow.

In 1878, Edison became interested in finding a good solution for light bulbs. The inventor operated by practical samples: carbonatious a lot of plants have set up different materials as a filament. 6 after thousands of experiments, he manages to make a lamp out of bamboo coals which works 40 hours. Edison light bulb starts to be produced EN masse, displacing the market the other lamps. In 1890, engineer Lodygin registers the use of the rod from tungsten, and later sells the patent of General Electric company.

Merits Edison

When developing lamp, Edison realized that in addition to the choice of materials is important and the design of the mechanism. So he invents a screw cap, lamp sockets, creates the fuses, counters, the first switches, generators. Many of the components for lighting, invented by Edison, are standard and are still used all over the world.

The Inventor has made it so that the bulb became widely available. To this end, he began to sell them at a lower price. Light bulb Edison cost a little more than a dollar. Plans to enterprising Americans to make the invention so affordable that even the wax candles seemed to be a luxury compared to him. Quick automation of production helped to reduce costs and thus to produce a large quantity of goods. Soon the cost of the lamp was about 22 cents. The dream of the inventor-light bulb appeared in every home.Edison light bulb photo

Edison Bulbs in the interior

Currently, light bulbs are common. They are available and very convenient to use. Moreover, there were many different types and modelslamps. Their practical significance has faded into the background, now they have become an important complement to the home interior.

“Edison light Bulb" (see photo above) is the name of a particular type of bulb. They are decorated in retro style and similar to those used in the days of Thomas Edison. These lamps emit a soft pleasant light, have a glass bulb or globe on the cord. Edison bulbs are often used for the design of public spaces-bars, cafes, or for the decoration of living rooms and bedrooms.
