First Light Bulb

First Light Bulb history is noted. The discovery of the light bulbs has a transversing history right from the early 1800's. Before that basically candles, gas lamps and oil lanterns were used as a source of light. In the year 1809, Humphrey Davy, an English scientist began his journey for discovering the incandescent source of light. A high power battery was used by him for inducing the current among the 2 strips of charcoal. The current flowing through these strips helped in producing the first arc lamp.

Then in the year 1820, Warren De la Rue made another attempt for the production of the incandescent light bulb. An electric was passed through a platinum coil in a void tube. The higher melting point of the platinum allowed the operation to take place at high temperatures. Although this was an effective design, the high cost of platinum did not make it workable for commercial use.

Then in 1860, Sir Joseph Wilson Swan, an English physicist invented an electric light that was long-lasting as well as practical. He invented that the filament of the carbon paper did a good job but they burn up very fast. In 1878, he gave a demo of his newly invented electric lamp in England.

In 1877, Charles Brush created carbon arcs for lighting the public square in USA. Thomas Edison experimented with a number of filaments for finding out the right material that will last for a long time as well as glow sufficiently. He invented that a filament of carbon glowed well in a oxygen free bulb in the year 1879. But the bulb did not burn for more than about 40 hours. He gradually produced a bulb that glowed for 1500 hours.

This bulb was later improved by Lewis Howard Latimer. He used a carbon filament in the bulb. In 1882, he patented and formulated a method of making carbon filaments. Then later on, Willis R. Whitney in the year 1903 discovered a treatment for this filament. This treatment stopped the darkening of the bulb from inside when it glows. And at last, William. D. Coolidge finally discovered the tungsten filament that lasted for a very long time as compared to all the filaments previously used for manufacturing the light bulb. And this was the first light bulb that revolutionalized the whole world and is in use even today.

This is how years after years; the first light bulb was finally invented and brought into existence through progression after successive years by different scientists. Can you just imagine what your life would have been before the invention of the first light bulb. Now it is so easy and convenient just to flip on the switch and you get on the lights.

You should know that the first light bulbs that were invented before lasted for about only 150 hours and ten years after that, Thomas Edison discovered a bulb that lasted for about 1200 hours. Today, an average light bulb lasts for a maximum of about 1500 hours.
