Who invented the lamp. strong> The lamp is a lighting tool. The name given to all of the devices that illuminate by burning a flammable substance, such as petroleum, or through the passage of electric current. Gas lantern, gas lantern, acetylene lantern, electric lamp, fluorescent lamp. X-ray lamps are the most commonly used lamp types.
The archaeological excavations in the lakes of Mesopotamia and Switzerland were accompanied by lanterns made of brick and bronze, and lamps made of bronze. The lamps used by the Greeks and Romans were cooked bricks and bronze.
In the eighteenth century, the Swiss chemist Aime Argand strong> worked on existing lamps and made a tubular roving. The wick, which had been compressed between the two mine cylinders, burned and was running low. One of the Swiss chemists’ helpers was able to put a glass bottle on this lamp. The glass prevented both the outflow of heat that disturbs the human being, but also that the light seemed brighter and did not go out.
Until 1845, melted animal oils, vegetable oils were used in the lamps.
The burning of this oil suddenly caused a lot of danger. This situation was overshadowed by the use of petroleum in lamps, and new developments in lamp construction were also evident. From there they were made, such as steering, single wick, double wick, mirror, round wick, hanging and corner lamps.
Because of the use of electricity in lighting, gas lamps lose their former significance and leave their place in the bulbs. > Electric lamp strong> is a filament-stranded and glass-enclosed lamp that emits light when heated by electricity. The incandescent and fluorescent lamp are two important light sources. The incandescent lamp used today is tungsten filament, which is heated up to 2600 ° C by electric current. Because the tungsten filament has a very high melting point of 3382 ° C, it continues to light for hours and without breaking. The glass part of the filament was evacuated and filled with a gas mixture of nitrogen and argon. This mixture does not enter the chemical reaction with the filament and prevents the evaporation of the filament when the lamp and the light with the pressurize light.
The average life span of incandescent lamps is 1000 hours.
In 1802, Humphry Davy strong> turned the electric current into platinum and incandescent it. But it did not investigate its possibilities for lighting. The first researcher who clearly recognized this possibility was J.W. Starr strong>. In one of Starr’s lamps, the electrically heated carbon rod was in a vacuum glass tube. Starr died in 1846 at the age of 25. Between 1848 and 1860, Swan used a carbonized paper strip as a flemish. The light bulb used is a light bulb made of emptied glass. The conducting wires were being isolated from the rubber material between them as they came out of the neck of the lamp. Swan could not make a practical lamp during this time period.
The construction of the lamps used in homes and offices will take place in Thomas Edison strong> and Swan strong>. Edison began his studies in 1877. Swan returned to this job 17 years later. Edison used a lot of materials as a flemish and eventually developed a carbonized cotton filament lamp that could be lit for about two days on October 21, 1879. But the winner was Swan in 1882.
On this date, they developed the lamp using Austrian Alexander Just strong> and Franz Hanaman strong> Tungsten wire. Production began in the US in 1907. In 1908, rolled tungsten was obtained. Thus, today’s lamps have begun to be produced. Share information multiplicity.
