Evolution of the light bulb

             The idea of light bulb invention goes back to thousands of years, when the main sources of lighting were candles and gas lamps. Several of inventers and companies from different countries attempt to bind a solution, which ended by remarkable evolution in the beginning of 1906 .

                         “In 1802, the scientist Warren De invented the first bulb light by connecting electricity through platinum coil in a tube, and due to the expense of the platinum this bulb light didn't last” (The History of the Light Bulb, 2011). Later scientists looked for a of filament that is available and not expensive like the previous one , when Joseph Wilson used the carbon paper but it produced dim light . The idea of this bulb light was improved by Thomas Eliot by using bamboo fiber filament. Mercury vapor, krypton gas, sodium vapor were used in improving the production of the bulb light till in 1906 when the tungsten filament was introduced in the bulb light production (The History of the Light Bulb, 2011).

            Henry Woodward and Matthew Evans formed the shape of the bulb light. After various thoughts and attempts inventors did, they ended to the production of light bulb in 1920s, and from that time till today scientists didn't stop in developing this invention such as trying to produce lights with more energy and searching for other methods to save the power to save the environment .

           In conclusion, Invention of light bulb is a creative process which joined a lot of efforts from different scientists. I believe that the invention of light bulbs has changed our life in a huge way, it made our life easier because we are not able to go anywhere without the light bulb, especially in the darkness.
