The Light Bulb – A Short History
The Light Bulb – A Short History
Ever wonder where the light bulb came from? The light bulb might be a common household item we take for granted today, but it is undoubtedly one of the most helpful and important inventions in the past few centuries. Looking back, during the early 1800s people only had candles and lamps to provide them with light. With the light bulb’s introduction, a very bright light source is available for a long time without having to light up another candle or change another wick.
Thomas Edison is widely recognized as the person who invented the light bulb. However, he only actually developed it to become more commercially practical; there have been other people before Edison who tried to develop it for widespread use. In fact, historians claim that there were 20 or more inventors who tried to create an incandescent light
There are three reasons why Edison’s version for the light bulb outstrips the others. First, it used an efficient incandescent material. Second, it has a high vacuum. Finally, it had high resistance, which made energy distribution taken from a centralized supply economically viable.
The First Light Bulbs
During the early 1800’s, Humphry Davy created what should be considered as the first functioning light bulb. Davy experimented on electricity and how it could be used for practical purposes; he ended up inventing the electric battery. Using wire and some carbon, he connected one end of the wire to the battery and the other end to carbon. The experiment resulted in the carbon glowing, producing light. Davy’s invention was then called the Electric Arc lamp. The
After a few years, many inventors were successful in creating “light bulbs”. However, their inventions were not too commercially friendly. The closest invention that had a practical design was Warren de la Rue’s model. He designed a light bulb that had an enclosed coil filament made from platinum inside a vacuumed tube, which then housed passing electrical currents. Since platinum has a very high melting point, the light produced could last for a long time. However, the price of platinum made the design very expensive and impractical for mass production.
The closest successful designs that were commercialized were from Henry Woodward and his partner Mathew Evans. Both filed a patent on July 24,
Thomas Edison eventually bought the patent and the rest, as they say, is history.
Thomas Edison’s Light Bulb
This discovery is the hallmark of the start of commercially-designed light bulbs. In 1880, Edison’s company called the Edison Electric Light Company, started marketing their new product to the masses.
Other Notable Events in the Light Bulb’s History
By the turn of the 1900s, more changes of the filaments being used in light bulbs were developed. Instead of carbon, tungsten was used for filaments in incandescent light bulbs. Edison was still the one who developed this change, but during the beginning of his experiments, he was unable to use tungsten because the machinery needed to create to fabricate
A decade later,
By the 30s, everyone saw the creation of little flashbulbs that were good for one-time use. This development
The Future of the
Currently, more and more light bulb developers are looking for ways to create bulbs that are energy efficient and eco-friendly. Many countries have passed bills and laws that support energy efficiency and low power use, even encouraging local light bulb producers to invest more time, money and research on bulbs like LEDs. Indeed, the future is definitely
