Electric lamp invention
Electric Lamp Invention. Through the efforts of edison and his co workers at menlo park in new jersey. Lamp tho electric lamp prior art date 1879 11 04 legal status the legal status is an assumption and is not a legal conclusion. In 1874 canadian inventors henry woodward and matthew evans filed a patent for an electric lamp with different sized carbon rods held between electrodes in a glass cylinder filled with nitrogen. Both the basic innovations of the jablochkoff arc light and the edison incandescent lamp appeared in the 1870s 1880s.

It was the availability of electricity creation by the newly developed self exciting dynamo that made is possible. On january 27 1880 thomas edison received u s. In addition to be the greatest inventor of his time. Both the basic innovations of the jablochkoff arc light and the edison incandescent lamp appeared in the 1870s 1880s. During one of his experiments he connected wires to one of his batteries and a piece of scrap carbon. That kind of electric lamp worked longer up to 1200 hours and gave better stronger light.

Edison after several attempts created the first incandescent lamp which was patented in 1880. In 1835 the first constant electric light was demonstrated and for the next 40 years scientists around the world worked on the incandescent lamp tinkering with the filament the part of the bulb that produces light when heated by an electrical current and the bulb s atmosphere whether air is vacuumed out of the bulb or it is filled with an inert gas to prevent the filament from oxidizing and burning out. In addition to be the greatest inventor of his time. Main design idea that prolonged working of the electric lamp was using of carbon filament in better vacuum. That kind of electric lamp worked longer up to 1200 hours and gave better stronger light. On january 27 1880 thomas edison received u s.

In 1870s sir joseph swann and thomas edison independently of each other made first electric lamp that could last longer than few hours by using carbon filament in vacuum. The lamps produce significant ultraviolet output they require ventilation when used indoors and due to their intensity they need protection from direct sight.
