The light bulb is the most important invention in history. This invention helps in
so many ways, most importantly; it helps us see when we are not able to, mostly at night.
The light bulb is an invention that is used all the time. The light bulb has impacted the
world in various ways. The only light source that was available consisted of candles, oil
lanterns, and gas lamps. It was a very long process to create the light bulb known today.
What the inventors mostly did was they kept on adding different filaments, or trying out
new filaments. It didn’t happen all at once, it took various people to keep on making it
better, to what the typical light bulb is today. Many people helped with the light bulb that
we know today.
The following people, Humphry Davy, Warren De La Rue, James Bowman
Lindsay, Edward Shepard, Joseph Wilson Swan, Heinrich Goebel, Hermann Sprengel,
Henry Woodward, Matthew Evans, Thomas Edison, Willis Whitney, and William David
Coolidge were all amazing people in which helped to make the light bulb we have today.
A science experiment will also be discussed in this essay. In the science experiment, it
will show which light bulb produces the most heat. The materials that will be used in this
experiment will be two light bulbs, a lamp, and a thermometer used to measure the heat
produced. The two light bulbs getting compared are an incandescent and a fluorescent
light bulb.
The invention of the incandescent light bulb has a history spanning as early as the
1800s. The only light source that was available before the light bulb consisted of candles,
oil lanterns, and gas lamps (invsee.asu.edu). In 1809, Humphry Davy, an English
Chemist began to work on the invention of the incandescent light source....

...ilament. It was a predecessor to the tungsten filament. In 1906 The General Electric
Company was the first to patent a method. It was to make tungsten filaments that were
used in incandescent light bulbs. The filaments were very expensive at that time when
In 1910 William David Coolidge then invented an improved method of making
tungsten filaments. This outlasted all the other types of filaments. This filament, unlike
the one The General Electric Company made, was much more cheaper and affordable for
the people. Coolidge made the price practical. Then later on in 1925 the first frosted light
bulbs were produced. Finally, in 1991, Philips, using magnetic induction, invented a light
bulb that lasted 60,000 hours (inventors.about.com). Although there were many light
bulbs being made, some of them were no longer going to be made or sold from the store
shelves.
Kerosene was an innovation that sparked more light into inventors eyes. After kerosene, innovations can be perfected not just in the day but now in night. Consequently, someone always thinks of more improved ideas. The light bulb was one of the greatest innovations during the Gilded Age; the everyday man can see in the dark. Normally, when the sun goes down, the men go down. This invention allowed people to carry on their "everyday lives" in the night. AC/DC electric lighting improved the light bulb even more so. Not just lighting one light bulb but lighting thousands. Carrying over to power houses; meaning a whole city or state can be

Controlling chemiluminescent light was how Omniglow Incorporated became the first company to produce light sticks. In 1986, when the first light stick was invented, scientists thought they could make a lot of money selling light sticks. However, since they had to make light sticks by hand, it was harder for them to produce very many of them. Until machines were invented to make light sticks, it cost too much money to make them by hand.
The light bulb is the way we see in the dark, the way we find our way, the way we know when to go at a stoplight. How did Thomas Edison achieve this invention? Knowledge. Knowledge of electricity and the needs of those around him. In The Great Gatsby, Daisy Buchanan claims that she wants her daughter to be “a beautiful little fool.” In other words Daisy is saying that ignorance is bliss. Some others believe that knowledge is power. The advancement from candles to light bulbs changed the culture entirely. People could easily do the work they needed to after sunset, and it even led to more inventions. We need knowledge to advance, and for this reason powerful knowledge is more valid than blissful ignorance.
During the ancient civilisation, candles were made from tallow, or animal fat, extracted from cattle and sheep. The first candles were developed by the ancient Egyptians. These candles, known as rushlights or torches, had no wicks and burned slowly. The Romans were credited for the first creation of candles with wicks, the ones that resembled the candles that are used today.
So he had to face the fact he had to invent something that can handle so much energy without that much copper and wire.so that was suitable for small houses to use the light bulb. As many times they took to make the light bulb was tested more than 3,000 times. He also had tested many metals to make the light bulb. He also tested more than 4,000 plants to handle the filament material. While he had tried to figure that out he had extra help with a group of scientists he was working with for 40 years to make the light bulb
Philips made a strong push to developing new technologies starting in the 1950s and 1960s. Upon doing so, the company also wanted to translate these technologies into products while adapting, producing, and selling these products within individual national markets. During this time period, most of the companies in the electrical products market were bring formed and racing to diversify. However, Philips decided to stick with what they knew best. They made only light-bulbs. In doing so, their strong focus enabled the company to create significant innovations. Continuing on, Philips also became a leader in industrial research by creating physics and chemistry labs to address both production and scientific problems. The labs developed a tungsten metal filament bulb that brought great commercial success. Philips simple structure and significant innovations gave them the financial support they needed to compete in a time period where competitors were seeking major growth.

Carbon fibers were discovered in the late 1800s by Thomas Edison. The early lightbulbs Edison created used the carbon fibers as filaments. These carbon fibers used to create the early lightbulbs had a substantial tolerance to heat, but they lacked the tensile strength of modern carbon fibers. Edison used cellulose-based materials, such as cotton or bamboo, to make his carbon fibers. He used a method called “pyrolysis” to cook the bamboo at high temperatures in a controlled atmosphere to carbonize bamboo filaments, making them fire-resistant and capable of enduring intense heat needed for luminescence.
Edison searched for the proper "filament" or wire, that would give good light when electricity flowed through it. He sent people to the jungles of the Amazon and forests of Japan in his search for a perfect filament material. He tested over 6,000 vegetable growths (baywood, boxwood, hickory, cedar, flax, bamboo) as filament material.
The history of engineering goes back into the 19th century when Alexander Volta (1745-1827) made a remarkable discover regarding the nature of electricity (Cosgrove 749). He discovered that electrical current could be controlled and could flow from one point to another. By the time the mid-19th century came about the rules for electricity were being established. During this time electromagnetic induction was discovered by Michael Faraday who lived from 1791 to 1867 (749). Also during this time Samuel Morris invented the telegraph in 1837 which relies on the principles of electromagnetic induction (749). Alexander Graham Bell, who lived from 1847 to 1922, created the telephone which also uses electricity in order to operate (749). Through the success of the telephone, Bell Telephone Company was established. In 1878, the light bulb was finally invented by Thomas Edison who lived from 1847 to 1931 (749). Off the principles of Faraday’s electric motor from 1821, Nicholas Tesla invented a more efficient and powerful electric motor in 1888 (749). To make these inventions be more significant, effort was expended to make better motors and transformers and to enhance the power needed to make them function. Through these inventions during the middle 19th century, it led to the capability of lighting homes and cities through the use of electricity, and it also led to the creation of the telephone communication system (750).
He starts to investigate how to create a light bulb that can last longer. Before Thomas Edison started making the light bulb, there were other inventors working on it, but no one could let the light bulb work longer. Eventually, on October 21, 1879, Thomas Edison’s light bulbs could work for forty hours. Thomas Edison and his team try to use the incandescent light bulb in the laboratory and at home. In 1880, Thomas Edison believed the incandescent bulbs could be produced and sold to the public.
Light bulb is one of the most influential inventions in the word. It makes us work more productive at night and helps us enjoy more activities at night. It significantly change people lives all over the world. The born of light bulb also helped us by making more inventions that related to light, such as phones, televisions, and computes. By using light bulb, we actually reduced the probability of having fire accidents because if we don’t have light bulb, we will use candles instead which can cause fire easily. There are a lot more benefits we get from light bulb, and all of these are credited to Thomas Alva Edison.
