How was the lightbulb made? He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. In 1850 an English physicist named Joseph Wilson Swan created a “light bulb” by enclosing carbonized paper filaments in an evacuated glass bulb.

What was the original light bulb made of?
The first commercially successful light bulb filaments were made from carbonized paper or bamboo. Carbon filaments have a negative temperature coefficient of resistance—as they get hotter, their electrical resistance decreases.
How did Edison's bulb work?
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.
How did the lightbulb work?
The light bulb creates light when electrical current passes through the metal filament wire, heating it to a high temperature until it glows. The hot filament is protected from air by a glass bulb that is filled with inert gas.
Background
From the earliest periods of history until the beginning of the 19th century, fire was man's primary source of light. This light was produced through different means—torches, candles , oil and gas lamps. Besides the danger presented by an open flame (especially when used indoors), these sources of light also provided insufficient illumination.
Raw Materials
This section as well as the following one (The Manufacturing Process) will focus on incandescent light bulbs. As mentioned earlier, many different materials were used for the filament until tungsten became the metal of choice during the early part of the twentieth century. Although extremely fragile,
Quality Control
Light bulbs are tested for both lamp life and strength. In order to provide quick results, selected bulbs are screwed into life test racks and lit at levels far exceeding their normal burning strength. This provides an accurate reading on how long the bulb will last under normal conditions.
The Future
The future of the incandescent light bulb is uncertain. While heating a filament until it glows is certainly a satisfactory way to produce light, it is extremely inefficient: about 95 percent of the electricity supplied to a typical light bulb is converted to heat, not light.

A Brief History of the Light Bulb
The electric light, one of the everyday conveniences that most affects our lives, was not “invented” in the traditional sense in 1879 by Thomas Alva Edison, although he could be said to have created the first commercially practical incandescent light. He was neither the first nor the only person trying to invent an incandescent light bulb.
Early Light Bulbs
In 1802, Humphry Davy invented the first electric light. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. His invention was known as the Electric Arc lamp.
Other Notable Dates
1906 - The General Electric Company were the first to patent a method of making tungsten filaments for use in incandescent lightbulbs.
INVENTION OF THE LIGHT BULB
The Industrial Revolution is one of the most significant events in all of world history and had a profound impact on the modern world. It began first in Britain in the 1700s but soon expanded to the rest of Europe and North America. Before the innovations of the Industrial Revolution, most production depended on water, wind or human energy.

Early research & development
The story of the lightbulb begins long before Edison patented the first commercially successful bulb in 1879. In 1800, Italian inventor Alessandro Volta developed the first practical method of generating electricity, the voltaic pile.
Joseph Swan vs. Thomas Edison
In 1850, English chemist Joseph Swan tackled the cost-effectiveness problem of previous inventors and by 1860 he had developed a lightbulb that used carbonized paper filaments in place of those made of platinum, according to the BBC.
First practical incandescent lightbulb
Where Edison succeeded and surpassed his competition was in developing a practical and inexpensive lightbulb, according to the DOE. Edison and his team of researchers in Edison's laboratory in Menlo Park, N.J., tested more than 3,000 designs for bulbs between 1878 and 1880.
LED lights
Light-emitting diodes (LEDs) are now considered the future of lighting due to a lower energy requirement to run, a lower monthly price tag and a longer life than traditional incandescent lightbulbs.

The Manufacturing Process
- The uses of light bulbs range from street lights to automobile headlights to flashlights. For each use, the individual bulb differs in size and wattage, which determine the amount of light the bulb gives off (lumens). However, all incandescent light bulbs have the three basic parts—the filament, the bulb and the base. Originally produced by hand, t...

The Future of The “First” Light bulb?
- Modern incandescent bulbs are not energy efficient – less than 10% of electrical power supplied to the bulb is converted into visible light. The remaining energy is lost as heat. However these inefficient light bulbs are still widely used today due to many advantages such as: 1. wide, low-cost availability 2. easy incorporation into electrical systems 3. adaptable for small systems 4. l…
