Before you begin the project, mark the label on each bottle with the date and event.
This way you can look up at your new light fixture and reminisce about the time each bottle was enjoyed.
Discharge lamps became the basis of many lighting technologies, including neon lights, low-pressure sodium lamps (the type used in outdoor lighting such as streetlamps) and fluorescent lights.
These early bulbs had extremely short lifespans, were too expensive to produce or used too much energy.When Edison and his researchers at Menlo Park came onto the lighting scene, they focused on improving the filament -- first testing carbon, then platinum, before finally returning to a carbon filament.Edison also made other improvements to the light bulb, including creating a better vacuum pump to fully remove the air from the bulb and developing the Edison screw (what is now the standard socket fittings for light bulbs).(Historical footnote: One can’t talk about the history of the light bulb without mentioning William Sawyer and Albon Man, who received a U. patent for the incandescent lamp, and Joseph Swan, who patented his light bulb in England. lighting company merged with the Thomson-Houston Electric Company -- the company making incandescent bulbs under the Sawyer-Man patent -- to form General Electric, and Edison’s English lighting company merged with Joseph Swan’s company to form Ediswan in England.) What makes Edison’s contribution to electric lighting so extraordinary is that he didn’t stop with improving the bulb -- he developed a whole suite of inventions that made the use of light bulbs practical.These new tungsten filament bulbs lasted longer and had a brighter light compared to the carbon filament bulbs.
In 1913, Irving Langmuir figured out that placing an inert gas like nitrogen inside the bulb doubled its efficiency.The following list contains the 424 patents Edison received concerning electric light and power.It is arranged in chronological order by execution date, which is the date on which Edison signed the application and the date in the patenting process that comes closest to the time of actual inventive activity.There was debate on whether Edison’s light bulb patents infringed on these other inventors’ patents. Edison modeled his lighting technology on the existing gas lighting system.In 1882 with the Holborn Viaduct in London, he demonstrated that electricity could be distributed from a centrally located generator through a series of wires and tubes (also called conduits).Scientists continued to make improvements over the next 40 years that reduced the cost and increased the efficiency of the incandescent bulb.
