The History of the Light Bulb
The Timeline of the Light Bulb -
Humphry Davy
Humphry started the journey to invent a light source. He used a high power battery to produce current between two charcoal strips. The current flowing through the two strips produced an light, creating the first lamp. -
Warren De la Rue
Warren made the first known attempt to produce a light bulb. He enclosed a platinum coil in a tube and passed an electric current through it. It was an efficient design, but the cost of the platinum made it impractical for commercial use. -
Faraday
Faraday demonstrates electro-magnetic rotation, the principle of the electric motor. -
Thomas Edison
Thomas Edison created a new lamp that used a carbon filament. This is the first light bulb that lasted for about 13.5 hours. -
James Bowman
James Bowman Lindsay used a prototype lightbulb to demonstrate a constant electric lighting system. -
Fox Talbot
Fox Talbot introduces photographic paper. -
Frederik de Moleyns
Frederik de Moleyns recieved the first patent for an incandescent lamp. -
Joseph Wilson Swan
Joseph Wilson Swan, an englishman, invented the first incandescent lamp with a paper filament. -
Joseph Wilson Swan
Joseph Wilson Swan begins installing electric light bulbs in landmarks and homes around England -
Public Display
Thomas Edison's first successful light bulb model was displayed in a public demonstration at Menlo Park. -
Thomas Edison
Thomas Edison kept working on his light bulb until it could shine for over 1200 hours. He used a filament derived from bamboo. -
Electric Lamp
Edison patented a system for electricity distribution which was essential to capitalize on the invention of the electric lamp -
New York City
New York became the first city to be lit by electric lights using generators designed by Thomas Edison. -
Gobel Vs Edison
Heinrich Gobel won court against Thomas Edison as the inventor of the electric lamp and recieved some profit. -
LED Lights
The first LED Lights were created by British experimenter H. J. Round using a crystal of silicon carbide and a cat's-whisker detector. -
William D. Coolidge
William D. Coolidge developed a light bulb that consists of a tungsten powder pressed into bars.When these were heated at extreem heats it formed a wire filament -
Soft Light
Light bulbs were now built with frosted glass to produce a soft light ,spreading light more evenly -
LED Lights
The first practical visible-spectrum (red) LED was developed in 1962 by Nick Holonyak, Jr. -
60,000 Hours
Philips creates a bulb that will shine for 60,000 hours using magnetic induction. -
A Flexiable Light Bulb
The team at Wake Forest University developed a light bulb where the material can emit any color and shape. -
Charles Darwin,
Charles Darwin wrote the The Origin of Species. -
Eco Friendly Light Bulbs
Many companies will create light bulbs where they can last for years to come, reducing the costs in energy.
