The Timeline of the Light Bulb
-
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 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 demonstrates electro-magnetic rotation, the principle of the electric motor.
-
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 Lindsay used a prototype lightbulb to demonstrate a constant electric lighting system.
-
Fox Talbot introduces photographic paper.
-
Frederik de Moleyns recieved the first patent for an incandescent lamp.
-
Joseph Wilson Swan, an englishman, invented the first incandescent lamp with a paper filament.
-
Joseph Wilson Swan begins installing electric light bulbs in landmarks and homes around England
-
Thomas Edison's first successful light bulb model was displayed in a public demonstration at Menlo Park.
-
Thomas Edison kept working on his light bulb until it could shine for over 1200 hours. He used a filament derived from bamboo.
-
Edison patented a system for electricity distribution which was essential to capitalize on the invention of the electric lamp
-
New York became the first city to be lit by electric lights using generators designed by Thomas Edison.
-
Heinrich Gobel won court against Thomas Edison as the inventor of the electric lamp and recieved some profit.
-
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 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
-
Light bulbs were now built with frosted glass to produce a soft light ,spreading light more evenly
-
The first practical visible-spectrum (red) LED was developed in 1962 by Nick Holonyak, Jr.
-
Philips creates a bulb that will shine for 60,000 hours using magnetic induction.
-
The team at Wake Forest University developed a light bulb where the material can emit any color and shape.
-
Charles Darwin wrote the The Origin of Species.
-
Many companies will create light bulbs where they can last for years to come, reducing the costs in energy.
