Who invented the light bulb and why did the invent it?

Answer 1

American, Peter Cooper Hewitt (1861-1921) patented (US. patent 889,692) the first Mercury vapor lamp in 1901. The low pressure mercury arc lamp of Peter Cooper Hewitt is the very first prototype of today's modern fluorescent lights. A fluorescent light is a type of electric lamp that excites mercury vapor to create luminescence.

Answer 2

The first "lamp" was probably invented thousands of years ago by the early humans who first discovered how to make fire!

But if you are really asking how the first electric lamp was invented...

The 1st light bulb was built by Humphry Davy (an Englishman) in 1809.

Thomas Alva Edison (an American) improved that invention and based his improvements on a patent he purchased from inventors Henry Woodward & Matthew Evans who patented their bulb in 1875.

Sir Joseph Wilson Swan produced an early electric lightbulb (1860), and in 1880, independently of Thomas Alva Edison, he produced a carbon-filament incandescent electric lamp.

Thomas Alva Edison (February 11, 1847 - October 18, 1931) was an American inventor, scientist and businessman who developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and a long-lasting, practical electric light bulb.

Thomas Edison gave us the first light bulb. Edison's most famous invention to come out of Menlo Park, California was the light bulb. Edison didn't invent electric lights--there were arc lights already, which were similar to today's street lights. They were very, very bright so people didn't want them inside their houses. At home, people used gas lights, but their open flames were dangerous and they flickered a lot. Edison didn't just invent a light bulb, either. He put together what he knew about electricity with what he knew about gas lights and invented a whole system of electric lighting. This meant light bulbs, electricity generators, wires to get the electricity from the power station to the homes, fixtures (lamps, sockets, switches) for the light bulbs, and more. It was like a big jigsaw puzzle--and Edison made up the pieces as well as fitted them together. One tough piece was finding the right material for the filament--that little wire inside the light bulb. He filled more than 40,000 pages with notes before he finally had a bulb that withstood a 40 hour test in his laboratory. (10) In 1879, after testing more that 1600 materials for the right filament, including coconut fiber, fishing line, and even hairs from a friend's beard, Edison and his workers finally figured out what to use for the filament--carbonized bamboo. The first large-scale test of the system in the United States took place when Edison’s Pearl Street station in New York City’s financial district sent electricity to lights in 25 buildings on September 4, 1882.

The Russian engineer Pavel Yablochkov invented the first lamp post in 1875. It was a carbon arc that was also called the Yablochkov candle.
