Video about the Mazda Bulb:. The move to metallic filaments: The Era of Tantalum. Tantalum Filaments: - Tantalum was the first metal filament on the market. Like tungsten it has a very high melting point, so it can be heated to incandescence without destroying itself like most metals.
Tantalum was so vastly superior to all other filaments that it became king from - After the sintered tungsten lamp really began to gain popularity. The arrival of a ductile tungsten finally ended the reign of tantalum. Werner von Bolton a Georgian living in Germany discovered that using tantalum for a filament allowed for lower energy consumption and greater brightness. Siemens and Halske Company produced these bulbs.
The tantalum filament became successful and became a major threat to General Electric's sales. This stimulated GE to invest more in it's recently formed research lab to try to come up with a better lamp. Below: The hooks used to hold filament. This filament was used in the famous Mazda lamps which produced a very bright light. Sintered Tungsten Filaments: Lodygin Russia in a "Exposition Universelle" in Paris.
Ductile Tungsten Filaments: - today. William D. Coolidge had been working with tungsten which proved to be a superior material for a long lasting lightbulb over any other material to date. Previous sintered tungsten filaments had been efficient, but brittle and not practical.
Coolidge figured out how to heat tungsten and draw it out through heated dies of decreasing diameter. The result of his work was a workable, bendable ductile wire that was high strength and made a great filament material. The new material was used in bulbs in and this is still used today. See our inventors section below for more advancements in the incandescent bulb. The future of incandescent lamps:. The Incandescent lamp has been in the average household for more than years.
In the last decade a major initiative to develop more efficient lightbulbs has replaced much of the world's bulbs with compact fluorescents. There has been significant resistance to bans on the incandescent bulb. Inventors and Developments. He also is the discoverer of the first electric lamp type: the carbon arc lamp. He is one of many people working on the incandescent light bulb from to the s.
Many French and Germans contributed to research on the incandescent bulb. Moleyns is exceptional and helped others build on the idea. Swan used carbonized paper as a filament in a partially evacuated bulb, this lasted several hours, which was a great achievement compared to the scores of inventors who couldn't get incandescence to last.
Swan continued to improve the bulb. He was able to succeed in creating the first reliable therefore marketable light bulb. His bulbs made after lasted a whopping hours. He then hired lots of talented engineers and created the world's most famous "invention factory". West Orange, New Jersey. The age of metallic filaments had begun and Siemens and Halske held the patent.

While the Cooper Hewitt lamps were more efficient than incandescent bulbs, they had few suitable uses because of the color of the light. By the late s and early s, European researchers were doing experiments with neon tubes coated with phosphors a material that absorbs ultraviolet light and converts the invisible light into useful white light. These findings sparked fluorescent lamp research programs in the U.
These lights lasted longer and were about three times more efficient than incandescent bulbs. The need for energy-efficient lighting American war plants led to the rapid adoption of fluorescents, and by , more light in the U. It was another energy shortage -- the oil crisis -- that caused lighting engineers to develop a fluorescent bulb that could be used in residential applications.
In , researchers at Sylvania started investigating how they could miniaturize the ballast and tuck it into the lamp. Two years later in , Edward Hammer at General Electric figured out how to bend the fluorescent tube into a spiral shape, creating the first compact fluorescent light CFL.
Like Sylvania, General Electric shelved this design because the new machinery needed to mass-produce these lights was too expensive. Consumers pointed to the high price as their number one obstacle in purchasing CFLs. Since the s, improvements in CFL performance, price, efficiency they use about 75 percent less energy than incandescents and lifetime they last about 10 times longer have made them a viable option for both renters and homeowners.
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. William David Coolidge, an American physicist with General Electric, improved the company's method of manufacturing tungsten filaments in Tungsten , which has the highest melting point of any chemical element, was known by Edison to be an excellent material for light bulb filaments, but the machinery needed to produce super-fine tungsten wire was not available in the late 19th century.
Tungsten is still the primary material used in incandescent bulb filaments today. Light-emitting diodes LEDs are now considered the future of lighting due to a lower energy requirement to run, a lower monthly price tag, and a longer life than traditional incandescent light bulbs.
Nick Holonyak, an American scientist at General Electric, accidently invented the red LED light while trying to create a laser in the early s. As with other inventors, the principle that some semiconductors glowed when an electric current was applied had been known since the early s, but Holonyak was the first to patent it for use as a light fixture. Within a few years, yellow and green LEDs were added to the mix and used in several applications including indicator lights, calculator displays, and traffic lights, according to the DOE.
Today, lighting choices have expanded and people can choose different types of light bulbs, including compact fluorescent CFL bulbs work by heating a gas that produces ultraviolet light and LED bulbs.
Several lighting companies are pushing the boundaries of what light bulbs can do, including Phillips and Stack. Phillips is one of several companies that have created wireless light bulbs that can be controlled via smartphone app.
The Phillips Hue uses LED technology that can quickly be turned on or off or dimmed by a flick on a smart phone screen and can also be programmed.
The higher-end Hue light bulbs can even be set to a large range of colors only about sixteen million and synced with music, movies, and video games. LED Icicle Lights. Replacement Bulbs. All Trees Wreaths All Christmas. Cart 0. The History of Incandescent Light Bulbs Did you know that Thomas Edison did not create the incandescent light bulb, but he only modified the invention to create it better? Check out this timeline.
