Light bulb incandescent schahl lamp or electric lighting equipment is a source of artificial light emitted from wire heated with electric current through it. It consists of a socket, wires and glass flask. Established by A. Lodigin in 1872 and its appearance is of a glass bubble filled with air, which are soldered two copper wires connected with charcoal stick. The trigger current carbonic wand lit about half an hour and then burned.
The first steps towards the modern bulbs were made in 1801 by Humphry Davy, who run an electric current through a platinum wire. It is generally believed schahl that the light bulb practical application created by Thomas Alva Edison, as in 1879 he made the first successful test. In 1875 Thomas Edison prolong her life, pulling air from the balloon.
Fifteen years after Lodigin placed incandescent tungsten and filling the balloon with nitrogen, thereby extending the life of the bulb. But before that, there were also lamps such as the Heinrich Goebel, dating back to 1854. From this period dates the first attempts to create a light bulb incandescent schahl Joseph Swann. Ten years later, his efforts schahl are paying off, but the light bulb has a short life. Only in the mid 70-ies of the XIX century, it managed to achieve real success. In essence, his invention represents a resistor.
In 1879, Thomas Edison first began selling incandescent light carbon fiber. In the twentieth century the Hungarian company "Tungsram" introduces the tungsten filament that has since been used in incandescent light bulbs. Tungsten filament is heated by an electric current, such as the temperature of the filament depends on the quantity and color of the light. The brightest light is emitted at 2700 degrees Celsius.
In 1882 in New York Edison built the first power plant that supplies energy ten thousand lamps. Thus was the beginning schahl of the rapid development of the age of electricity. In modern tungsten filament bulbs lit, while the passage of electric current through it, it heats up to about 2700 degrees Celsius and emits white light. The standard lamp of 75 or 100 watts (120 volts) the temperature is about 2550 degrees Celsius, or about 4600 degrees schahl Fahrenheit. With such a high temperature the thermal radiation from the fiber to cause any significant amount of visible light.
