A Short History of the Light Bulb




The electric light bulb is one of the most convincing symbols of technological development. From the early perception of the 19th century shift to the present where the image of the bulb is still used to represent the idea of ​​a good idea, the lamp's design has changed relatively small. But with efficiency requirements and customer search, it becomes more advanced lighting technology once again to change quickly. In this article, I will map the lamp's progress, from the beginning with the earliest platinum filament experiments to today's most advanced LED lights. One of the most consistent and interesting themes in this area is the aversion to changing what inventors and innovators face for each new technological development. This point can be illustrated with the light lamp; The lamp was designed to replicate the light aesthetics in fittings as chandeliers (the earliest chandeliers functioned purely as a way to increase light output from light). The light-shaped bulb is now one of the most popular CFL styles due to the potential cost savings from multiple light bulbs.

When discussing the light bulb, a name has more prolifically than anyone else, Thomas Edison. Historians Robert Friedel and Paul Israel named over twenty inventors of the light bulb before Edison, although they concluded that Edison's design outperformed past attempts due to efficiently glowing materials, higher vacuum and higher resistance making the bulb easy to operate and therefore economically profitable. Thomas Hughes described the success of Edison's design to the fact that he had invented an entire lighting system, other inventors with generators and light bulbs, and comparable inventiveness and excellence have long been forgotten because their creators do not preside over their introduction into a lighting system (Hughes). The first light bulb was created by Humphry Davy in 1802, 45 years before Edison was born, by providing an electric current through a thin platinum plate, chosen for its high melting point. The light produced was not bright enough or it was long enough to be practical. James Lindley raised the relay in 1835 and demonstrated his electric light at a public meeting. but he then turned to other fields leaving the road for Walter De la Rue. In 1840, De la Rue passed an electric current through a flushed platinum filament – released in vacuum. The theory is that an evacuated bulb would contain fewer gas molecules to react with platinum, which prolongs its illumination time. This was a significant improvement; however, the use of platinum made the design impractical for commercial use. In 1858, Joseph Wilson Swan began working on carbon fiber filaments but was hampered by the lack of a good vacuum until he joined Charles Stearn, an expert on vacuum pumps. The Swan then turned its attention to efficiency and produced better carbon filaments, and in 1880 he began installing light bulbs in his home in Gateshead, England. Thomas Edison began to examine the light bulb in 1878 and settled on the carbon filament. His first test in 1879 lasted for 13.5 hours, but several months later, Edison discovered that a carbonated bamboo filament could be over 1200 hours. Meanwhile, Hiram S. Maxim began his US Electric Lighting Company to become the second man, after Edison, to install light bulbs at the Mercantile Safe Deposit Company in New York City. Edison and Swan joined forces to form Ediswan (later become Thorn lighting), and eventually Edison acquitted all Swan's interests in the company. Progress continued and in 1910, William David Coolidge discovered a method to make tungsten filaments more efficient, making the bulb even more cost effective. From 1913 to 1930, innovators showed their attention to the use of inert gases in the bulb to further improve efficiency. In 1930, Imre Brody settled on a mixture of krypton and xenon and to reduce costs, he also developed a method to get krypton from the air at his factory in Ajka, Hungary.

The most recent significant developments in the lighting sector have been the introduction of energy saving & # 39; bulbs or compact fluorescent lamps (CFL). Although considered to be a relatively modern invention, CFLs were first imagined by Pete Cooper in the late 1980s and were originally used in the photography industry. The first practical fluorescent lamp was designed by George Inman from General Electric and became the drawing for the modern CFL invented by Ed Hammer and General Electric in response to the oil crisis in 1973. Although the construction met all its requirements, it was never mass-produced due to the cost of mass production , but the design then leaked and copied. The steady increase in CFL production continues to this day, but consumption is expected to increase sharply with the decommissioning of inefficient bulbs. In September 2012, no incandescent bulbs will be available to reduce carbon dioxide emissions and consumer energy costs. So what is the future of electric lighting? Many believe that the answer lies with LED lights. Originally used in units such as alphanumeric displays and pocket counters, the LED lights have recently been successful in commercial and domestic lighting applications. LED lamps can be up to 50,000 times as long as incandescent lamps and the most advanced bulbs can produce a high light source while consuming a fraction of the energy. Although the original cost of the lighting is high, the lamps will pay more than themselves for their lifetime. LED lamps have a fast on / off time and can handle a high cycle cycle making them ideal for car lights, theatrical lights, traffic lights and dynamic road signs, as well as household and household lighting. It is obvious that lighting technology has come a long way since Edison's first experiment and the contact we have with lighting encourages daily progress to continue.
