The document discusses the history of the light bulb, from early unsuccessful attempts in the 18th century to the breakthrough of Thomas Edison in the late 19th century. It describes experiments before Edison with electric arcs and carbon filaments that did not last long enough. Edison was eventually able to create a carbonized thread that burned for 13 hours in 1879, leading to his successful commercialization of the light bulb. While light bulbs are now commonplace, research continues to improve efficiency and performance.

Electric light bulbs never used to be so simple and technologically advanced in the 19th century
and in our modern day we disregard this privilege. Over two centuries ago the only source of light,
excluding natural sunlight, was candles, gas lamps and lanterns. With the excitement of the
founding of electricity in the 18th century, the concentration of producing an electric powered light
bulb soared immensely.
Many of the initial attempts to create something so revolutionary failed as scientists found it
difficult to perfect the light as it was different to anything they had ever seen before. Thomas
Edison is the widest known creator of the light that lit up the world but there were attempts before
him that very nearly perfected the invention.
In 1806, 70 years before Thomas Edison introduced his invention to the world; Humphrey Davy
created a powerful electric lamp and demonstrated it to the Royal Society. It consisted of two
charcoal rods which when fused together by electricity created a blinding spark of light - this was
then rejected as the light was so bright it was impractical for home and work purposes. Another
disadvantage to this was that it needed a great source of power to run meaning that it went out
very quickly. Despite this, efforts were made to split the light into a healthy source to brighten up
rooms, which eventually failed. This specific type of light was however reinforced when electric
generators were invented and they were used in lighthouses and to power huge searchlights
during wars.
A completely new technique was introduced into the scientific world which was named
'incandescence' and was a more promising source of electric lighting. This started as scientists
were aware that if you passed electricity through some materials they would eventually heat up
and glow but this research usually resulted in the material melting or bursting into flames. With the
progression through science for incandescent lighting a lot of alternative materials and ways of
maintaining the glow were discovered and researched.
Several patents were given to scientists who discovered new ways of designing these lights after
realising the huge profit that would come out of perfecting the creation. British born Frederick
DeMoleyns patented a bulb which used the technique of starving platinum and carbon of oxygen
as the electricity was passing through which would then prevent the materials from coming alight.
Along with other improvements on electric lighting, these never proved practical enough to be sold
for everyday use.
It was not until Thomas Edison began researching to create a better light bulb after recognising
the financial success that it would bring. Edison was popular for creating many inventions such as
the phonograph and the motion pictures kinetoscope. After only a few months of working on the
incandescent light bulb project he declared to newspapers that he had solved the problem of

perfected the creation.
In October 1879 Edison began to see results as he had created a carbonized thread which burned
for 13 hours during an experiment and he was given a patent for this. Months after the patent was
given, Thomas Edison used carbonized bamboo burners, now called filaments, which burned for a
fantastic 600 hours. After such a break-through for electric lighting, he established Edison
Electrical Light Company in 1882 and began to light up New York.
Although we are oblivious to the use of electric lighting in this present day, research is still being
carried out to create light bulbs which are more energy efficient and improve the light bulb overall.
The results may not be as revolutionary as the work of Thomas Edison but there has been an
astonishing improvement since the birth of lighting itself.
