Who invented incandescent light globes




















Morgan and other wealthy investors of the time. The company constructed the first electrical generating stations that would power electrical system and newly patented bulbs.

The first generating station was opened in September on Pearl Street in lower Manhattan. Other inventors, such as William Sawyer and Albon Man, threw in the towel, merging their company with Edison's to form General Electric, according to the U.

Department of Energy DOE. Where Edison succeeded and surpassed his competition was in developing a practical and inexpensive light bulb , according to the DOE. Edison and his team of researchers in Edison's laboratory in Menlo Park, N.

In November , Edison filed a patent for an electric lamp with a carbon filament. The patent listed several materials that might be used for the filament, including cotton, linen and wood.

Edison spent the next year finding the perfect filament for his new bulb, testing more than 6, plants to determine which material would burn the longest. Several months after the patent was granted, Edison and his team discovered that a carbonized bamboo filament could burn for more than 1, hours.

Bamboo was used for the filaments in Edison's bulbs until it began to be replaced by longer-lasting materials in the s and early s. In , Lewis Howard Latimer, one of Edison's researchers, patented a more efficient way of manufacturing carbon filaments. And in , Willis R. Whitney invented a treatment for these filaments that allowed them to burn bright without darkening the insides of their glass bulbs. MR Bulbs. PAR Cans. Stage Light Bulbs. Dimmer Packs.

DJ Lighting Stands. LED Downlights. LED Strips. LED Color Changer. The culmination of all his work was his development of a long-lasting light bulb. Like its predecessors, it used a filament contained within an evacuated tube except he replaced carbonized paper with cotton thread. He patented his design in and would later come into direct conflict with Thomas Edison. Another interesting attempt was made in by a pair of Canadian inventors. Henry Woodward and Mathew Evans , both Toronto-based, designed and built their own light bulbs.

The pair created a range of bulbs of different sizes and shapes that used c arbon rods held between electrodes in glass cylinders filled with nitrogen. Woodward and Evans attempted to commercialize their lamp but were unsuccessful. They eventually sold their patent to Thomas Edison in In , the same year Swan filed and was awarded his patent in England, Thomas Edison decided to turn his attention to the development of electric light bulbs.

Edison, ever the keen businessman, wanted to develop a commercially viable and practical version to bring to market. He hoped to muscle in on the lucrative gas and oil lighting market in the United States. If he could break the hegemony of these two systems, he might just be able to make a fortune.

In October of , he finally patented his first application for an "Improvement In Electric Lights" with the patent office.

But he didn't stop there. Edison continued to work on and refine his designs. He experimented with different metals for filaments to improve the performance of his original patent.

In , Edison filed another patent for an electric lamp that used " a carbon filament or strip coiled and connected This patent also described the possible means of created said carbon filament. These included the use of "cotton or linen thread, wood splints, and papers coiled in various ways.

He showed that when electric current flowed through wires, their resistance caused them to heat up to the point where they gave out light. US inventor Thomas Edison is often credited with creating the solution in the carbon filament light bulb.
