| | History of light bulb:
During an epoch of antiquity, Greeks had an oil lamp - clay or metallic “small kettle” with oil and wick is passed through the kettle’s spout. Lamp smoked many centuries because lamp glass was invented only in second halve of XVIIIth century.
In the middle of XIXth century, kerosene was obtained from petroleum oil and use of kerosene lamp began. Simultaneously, inventors developed gas and gas burners made their way into the lives. Gas-drop lamps were especially bright. Incandescent gauze mantle made from refractory metals produced light in the gas-drop lamps. These lamps were used till 30s of our century.
Spirit-drop lamps were also used, in which spirit was burnt to produce light. In 1802, popular Russian inventor Vasily Petrov made tremendous invention. If tips of coal cores are brought closer and pass current through them, then dazzling arched flame — an electric arc flickers between them. In 1849, such arc lamp has been established on the Admiralty tower.
However, coal cores burn and also it is necessary to move them constantly, which is not absolutely convenient. For this purpose, scientists came out with an excellent regulator.
Simultaneously, Russian scientist Pavel Nikolaevich Yablochkov thought of simply placing the cores close in columns and to place an insulator, which is not a current conductor, between the coal cores. In 1876, “Yablochkov candle” conquers the entire world — from America to Cambodia.
At the same time, first electric incandescent lamp - later known as light bulb - of American scientist Thomas Edison appears. |
