Heating metal
Ebenezer Kinnersley heated a metal tube creating light. His “invention” was used everywhere and was vary popular during the 1700’s -
The Electric Arc Lamp
In 1802, Humphry Davy invented the first electric light. He connected wires and pieces of carbon together. The carbon glowed when connected to the battery, and he called it the Electric Arc Lamp. The lamp didn’t produce light for long and was much too bright for practical use. -
James Bowman Lindsay
James Bowman Lindsay created the first indecensent light bulb. His product was never marketed due to his impopularence and that he didn’t have enough money to put it on market. -
Warren de la Rue
In 1840, a British scientist named Warren de la Rue, put a coiled platinum inside a vacuum tube and shot an electric current through it. He thought that the high melting point of the platinum would allow it to be used in high temperatures and thought that the platinum would release less gases and particles in the air. His product never hit the stock market due to the prices of platinum. -
Light bulb
In 1850 an English physicist named Joseph Wilson Swan created a light bulb.He created a usable light bulb but the vacuum tube could not withstand the electric pulses. -
Nitrogen gas
On July 24, 1874 a pariant was filed by a Toronto medical electrician named Henry Woodward and his colleague Mathew Evens. They worked together and built their lamps with shapes and sizes of all sorts, made of carbon rods between electrodes in glass cylinders filled with nitrogen gas -
Light bulb part 2
In 1878, better vacuum tubes, which could conduct more electrical currents, were created which allowed Joseph to further conduct experiments. This was his last experiment and invention before he died. -
The introduction to Thomas Edison
Eventually, Henry and Mathew tried to commercialize their product, but never sold. Both eventually agreed to sell their first product to Thomas Edison in 1879 -
Thomas Edison’s research
Thomas Edison, became indulged in research to develop a practical electrical light bulb. He introduced himself for an application for “improvement in electrical lights” in October 14, 1878. In November 4, 1879, Thomas Edison filed another U.S. colleague for an electric lamp using "a carbon filament or strip coiled and connected ... to platina contact wires." -
Nikola Tesla
Nikola Tesla was trying to create the first electric lightbulb. He and Thomas Edison worked together for years. Eventually Nikola Tesla and Edison stopped being partners but Nikola told Edison what should and shouldn’t happen. -
Frosted lightbulb
The first frosted light bulb was invented in 1920. Technology couldn’t make enough wires so these products did not sell well. -
Imre Brody
Imre Brody replaced argon with krypton gas in the lightbulb. He thought that krypton gas would be a better and more efficient way of light, since it burns longer and brighter than argon. His product was never sold tue to the cost of krypton. -
The flashbulb
The flashbulb was invented in 1930. It was used for photography. -
Quartz Glass
In 1950, quartz glass was starting to be used more often and fluently. -
Low wattage light bulb
In 1980, low wattage bulbs were starting to be used. They were incredibly helpful and are still used to this day. -
The LED
In 2009, the first led was entered into the L Prize 60-watt replacement category. This was due to the study in 2010 approximately 971 million 60-watt bulbs in use. Of course the producers had no idea about this study but were extatique to here about this study due to the fact that they knew that their bulb was using under 60-watts.
