Who invented bulb light

He did this by connecting voltaic piles to charcoal electrodes. This invention was known as an eclectic arc lamp. The lamp burnt out very quickly and was a little too bright for use in a home or office space.

However, the principles both Davy and Volta put in place made a significant impact in the s in the development of other electric lamps and bulbs. In there was a significant development, British scientist Warren de la Rue evolved an efficient functioning lightbulb using coiled platinum filament in the place of copper.

The problem was, the high cost of this platinum held the bulb back from becoming a huge commercial success. The same problem arose in when William Statie improved the longevity of arc lamps by developing a mechanism that regulated and slowed down the carbon rods, which were before quick to erode. In , English chemist Joseph Swan attempted to resolve the issues previous inventors had encountered in terms of cost-effectiveness. In he developed a light bulb that replaced expensive platinum with carbonised paper filaments.

According to the Smithsonian Institution, in February Swan presented his working lamp in a lecture in Newcastle. While the prototype worked well for demonstrative performance, it was impractical in actual use. Edison showcased his lightbulb in December As a way of thanking him for saving his child's life, the father taught Thomas how to use the telegraph.

Thomas became so good at using the telegraph that he got a job working as a telegrapher sending signals between the United States and Canada. He began experimenting with ways to improve the telegraph, which led to his invention of the automatic telegraph, duplex telegraph, and message printer. It was about this time that Thomas dedicated his life to being a full-time inventor. He continued his work on the telegraph and his ideas also gave birth to the universal stock ticker.

His father Samuel supervised the construction of the new laboratory; it opened in In the period from to Edison and his associates worked on at least three thousand different theories to develop an efficient incandescent lamp. Incandescent lamps make light by using electricity to heat a thin strip of material called a filament until it gets hot enough to glow. Many inventors had tried to perfect incandescent lamps to "sub-divide" electric light or make it smaller and weaker than it was in the existing arc lamps, which were too bright to be used for small spaces such as the rooms of a house.

Edison's lamp would consist of a filament housed in a glass vacuum bulb. He had his own glass blowing shed where the fragile bulbs were carefully crafted for his experiments. Edison was trying to come up with a high resistance system that would require far less electrical power than was used for the arc lamps. This could eventually mean small electric lights suitable for home use. By January , at his laboratory in Menlo Park, New Jersey, Edison had built his first high resistance, incandescent electric light.

It worked by passing electricity through a thin platinum filament in the glass vacuum bulb, which delayed the filament from melting. Still, the lamp only burned for a few short hours. In order to improve the bulb, Edison needed all the persistence he had learned years before in his basement laboratory. He tested thousands and thousands of other materials to use for the filament.

He even thought about using tungsten, which is the metal used for light bulb filaments now, but he couldn't work with it given the tools available at that time. So similar was Edison's own invention that Swan decided to sue Edison for copyright infringement.

British courts ruled against Edison and as punishment Edison had to make Swan a partner in his electric company. Later, even the U. But, despite all this, Edison would forever be remembered as the inventor of the light bulb. Thomas Edison would go on to become one of the most prolific inventors and businessman of the 19th and 20th Century.

By the time of his death, he had acquired a mind-boggling 2, patents with alone for electric lighting and power. Whilst Thomas Edison does, rightfully so, get some 'heat' for 'stealing' many of Nikola Tesla's inventions and developments, the light bulb is not one of them. In fact, Tesla spent little, if any, of his time, developing incandescent electrical lighting of any kind.

Tesla did, however, make contributions to the development of arc lighting. He also conducted some interesting experiments into the possibility of wireless lighting. But claims regarding Edison's own invention of the light bulb, as we have seen, is arguable.

But what cannot be denied is the fact that Edison, unlike all inventors of the light bulb before him, was able to create a commercially viable and reliable design. For this reason, and his business acumen in general, it would be Edison's design and Joseph Swan's that would become ubiquitous around the world.
