We all know that today we always
used an LED lamp. Did you know what people used to light a room in more than 60
years ago? In 60 years ago human use a incandescent lamp. The incandescent lamp is a source of artificial
light generated by channeling electric current through the filament which then
heats up and produces light. Glass that envelops the hot filament to connect
with blocking the air so that the filament will not directly damaged by
oxidation.
In 1879 edison was made a
incandescent lamp, that makes his names remembered forever. But, edison not the
first person that makes electric lighter. A few years before 1879, lamp that
used electric was exist and used for light the way in paris. But, edison incandescent
lamp is more efficient and make a chance to have a simple lighter in home. In
1882 his company start producing electric for houses in New York, and for a
short time, this thing has spread to all countries in world. We all need to appreciate Edison
work for the time of making this incandescent lamp.
Edison has give a big
contribution, he has make more than 1000 thing like projector, telegram, and
coffee maker. Edison says in his biographics that’s he has do 999 fail in his
project of light bulb and in the 1000 try, he found the light bulb. He was a
super diligent man that he won’t fail make a light bulb. If Edison didn’t do
that 999 fail and finish at 1000 try, what will the light bulb seen right now.
I didn’t fail, I just found 999
ways to didn’t make light bulb. Edison was once says that after making his
light bulb. Thomas Edison began serious research into developing a practical
incandescent lamp in 1878. Edison filed his first patent application for
"Improvement In Electric Lights" on 14 October 1878. After many
experiments, first with carbon in the early 1880s and then with platinum and
other metals, in the end Edison returned to a carbon filament. The first
successful test was on 22 October 1879, and lasted 13.5 hours. Edison continued
to improve this design and by 4 November 1879, filed for a US patent for an
electric lamp using "a carbon filament or strip coiled and connected ...
to platina contact wires." Although the patent described several ways of
creating the carbon filament including using "cotton and linen thread,
wood splints, papers coiled in various ways,"Edison and his team later
discovered that a carbonized bamboo filament could last more than 1200 hours.
In 1880, the Oregon Railroad and Navigation Company steamer, Columbia, became
the first application for Edison's incandescent electric lamps.
