History Glow Lamp



Incandescent lamps are lit and filamennya.



Fluorescent lamp

Incandescent lamps are the source of artificial light generated through the distribution of electric current through a filament which is then heated and produces cahaya.Kaca surrounding air prevents the hot filament to get in touch with him so that the filament will not directly damaged by oxidized.
Incandescent lamps are marketed in various forms and are available for voltage (voltage) the work range from 1.25 to 300 volts of electricity required volt.Energi incandescent lamp to produce a bright light is bigger than any other artificial light sources like fluorescent lamps and diode light, then gradually in some countries began to be restricted circulation of incandescent lamps.
In addition to the use of light produced, several more take advantage of the use of incandescent heat generated, for example, is heated chicken coop, and infrared heater in the heating process in the industry.

History

Development of fluorescent lamp has been started at the beginning of the century XIX.Sejarah incandescent lamps can be said to have begun with the discovery of the voltaic pile by Alessandro Volta.

In 1802, Sir Humphry Davy showed that electric current can heat up to light a thin strand of white metal.

Then, in 1820, Warren De la Rue to design a lamp by placing a coil of precious metal platinum in a tube and a current of electricity melaluinya.Hanya course, the price of platinum metals are very high utilization of the present invention prevents more carbon lanjut.Elemen was used, but carbon can be oxidized rapidly in air; therefore, the answer is to place elements in a vacuum.

In the 1870s, an inventor named Thomas Alva Edison of Menlo Park, the state of New Jersey, United States, began to participate in the efforts to design lamps pijar.Dengan using platinum element, Edison receive his first patent in April of this 1879.Rancangan relative impractical but Edison still trying to find another element that can be heated economically and efficiently.

In the same year, Sir Joseph Wilson Swan has also created an incandescent lamp can last for 13.5 hours. Most of the incandescent filament lamp which was created at that end within a very short time so it does not mean commercial. To resolve this problem, Edison again try to use strands of carbon that is placed in a vacuum bulb until the date of October 19, 1879 he managed to turn on the lights that can last for 40 hours.
