Nov 22, 2013 · In the 19th century, two Germans -- glassblower Heinrich Geissler and physician Julius Plücker -- discovered that they could produce light by removing almost all of the air from a long glass tube and passing an electrical current through it, an invention that became known as the Geissler tube.

In the 18th century, the central burner was invented, a major improvement in lamp design. The fuel source was now tightly enclosed in metal, and an adjustable metal tube was used to control the intensity of the fuel burning and intensity of the light. Around the same time, small glass chimneys were added to lamps to both protect the flame and contr...
Early lighting fuels consisted of olive oil, beeswax, fish oil, whale oil, sesame oil, nut oil, and similar substances. These were the most commonly used fuels until the late 18th century. However, the ancient Chinese collected natural gas in skins that were used for illumination. In 1859, drilling for petroleum oil began and the kerosene (a petrol...
In 1792, the first commercial use of gas lighting began when William Murdoch used coal gas for lighting his house in Redruth, Cornwall. German inventor Freidrich Winzer (Winsor) was the first person to patent coal gas lighting in 1804 and a "thermolampe" using gas distilled from wood was patented in 1799. David Melville received the first U.S. gas ...
Sir Humphrey Davyof England invented the first electric carbon arc lamp in 1801. A carbon arc lamp works by hooking two carbon rods to a source of electricity. With the other ends of the rods spaced at the right distance, electrical current will flow through an "arc" of vaporizing carbon creating an intense white light. All arc lamps use current ru...
Sir Joseph Swann of England and Thomas Edisonboth invented the first electric incandescent lamps during the 1870s. Incandescent light bulbs work in this way: electricity flows through the filament that is inside the bulb; the filament has resistance to the electricity; the resistance makes the filament heat to a high temperature; the heated filamen...
Contrary to popular belief, Thomas Alva Edison did not "invent" the first lightbulb, but rather he improved upon a 50-year-old idea. For example, two inventors that patented the incandescent light bulb before Thomas Edison did were Henry Woodward and Matthew Evan. According to the National Research Council of Canada: Suffice it to say, light bulbsd...
American, Peter Cooper Hewitt patented the mercury vapor lamp in 1901. This was an arc lamp that used mercury vapor enclosed in a glass bulb. Mercury vapor lamps were the forerunners to fluorescent lamps. High-pressure arc lights use a small bulb of high-pressure gas and include mercury vapor lamps, high-pressure sodium arc lamps, and metal halide ...
American, Irving Langmuir invented an electric gas-filled tungsten lampin 1915. This was an incandescent lamp that used tungsten rather than carbon or other metals as a filament inside the lightbulb and became the standard. Earlier lamps with carbon filaments were both inefficient and fragile and were soon replaced by tungsten filament lamps after ...
Friedrich Meyer, Hans Spanner, and Edmund Germer patented a fluorescent lampin 1927. One difference between mercury vapor and fluorescent lamps is that fluorescent bulbs are coated on the inside to increase efficiency. At first, beryllium was used as a coating however, beryllium was too toxic and was replaced with safer florescent chemicals.
U.S. Patent 2,883,571 was granted to Elmer Fridrich and Emmett Wiley for a tungsten halogen lamp - an improved type of incandescent lamp - in 1959. A better halogen light lamp was invented in 1960 by General Electric engineer Fredrick Moby. Moby was granted U.S. Patent 3,243,634 for his tungsten halogen A-lamp that could fit into a standard light b...
- Early research & developments. The story of the light bulb begins long before Edison patented the first commercially successful bulb in 1879. In 1800, Italian inventor Alessandro Volta developed the first practical method of generating electricity, the voltaic pile.
- Joseph Swan vs. Thomas Edison. In 1850, English chemist Joseph Swan tackled the cost-effectiveness problem of previous inventors and by 1860 he had developed a light bulb that used carbonized paper filaments in place of ones made of platinum.
- The first practical incandescent light bulb. Where Edison succeeded and surpassed his competition was in developing a practical and inexpensive light bulb, according to the DOE.
- Tungsten filaments. William David Coolidge, an American physicist with General Electric, improved the company's method of manufacturing tungsten filaments in 1910.

Jul 18, 2023 · Humphry Davy (1778–1829) invented a very early form of arc lamp, which produced light by an electric arc, also called a voltaic arc.
Thomas Edison is credited with inventing a whole host of valuable inventions but the real story behind them often reveals a different pattern of events. It was actually British inventor Sir Humphry...
