Light bulbs are one of the most enduring signs of technological progress.From the early 19 th century concept to the present, the image of the bulb is still used to represent a good idea concept, and the design change of the bulb is relatively small.However, lighting technology is changing rapidly as efficiency requirements and customer tastes improve.In this article, I will draw a progress map of the bulb.Light bulbs are one of the most enduring signs of technological progress.From the early 19 th century concept to the present, the image of the bulb is still used to represent a good idea concept, and the design change of the bulb is relatively small.However, lighting technology is changing rapidly as efficiency requirements and customer tastes improve.In this article, I will draw the progress of the bulb, starting with the earliest platinum wire experiment, to the most advanced LED bulb today.One of the most consistent and interesting topics in this subject area is that inventors and innovators hate change in every new technological advancement.This can be explained by candle bulbs;The bulb is designed to replicate the aesthetics of the candle in accessories such as chandeliers (the earliest chandelier is purely to increase the light output of the candle ).Due to the potential cost savings of multiple bulb accessories, candle-shaped bulbs are now one of the most popular CFL styles.When Thomas Edison discusses incandescent lamps, a name is more attractive than any other name.Historians Robert Fridel and Paul Israel appointed more than 20 inventors of light bulbs before Edison, but they concluded that due to the effective incandescent material, the design of Addison exceeds the higher vacuum and higher resistance, making the bulb easy to supply power and therefore economically viable.Thomas Hughes attributed the success of edison solar\'s design to his invention of the entire lighting system, other inventors with generators and incandescent lamps, and considerable ingenuity and excellence, because their creators did not host their introductions in a light system, they were long forgotten.The first incandescent lamp was manufactured by Humphrey David in 1802, 45 years before Edison was born, and it was produced by passing current through a thin platinum strip, which is highThe light generated is not bright enough, and it is not long enough to be actually used.On 1835, James Lindley showed his lights at a public meeting.However, he then turned his attention to other areas, clearing the way for Walter de la Street.Transfer current through coiled platinum filaments on 1840 De la Street-Enclosed in a vacuum.The theory is that the evacuated bulb contains less gas molecules that react with platinum, thus prolonging its lighting time.This is a major progress;However, the use of platinum makes this design not commercially feasible.In 1858, Joseph Wilson Swan began to use the carbide paper silk, but he was hampered by the lack of a good vacuum until he worked with Charles Sten, an expert on vacuum pumps.Swan then turned his attention to efficiency and produced better carbon silk. In 1880, he began installing light bulbs at his home in Gateshead, England.Thomas Edison began studying incandescent lamps in 1878, settling down on the carbon silk.His first test in 1879 lasted 13 years.A few months later, however, Edison found that the treated bamboo silk could last more than 1200 hours.Meanwhile, in the United StatesS Hiram S.Maxim founded his American electronic lighting company, becoming the second person to install incandescent lamps at the New York City commercial safety deposit company after Edison.Edison and Swan joined hands to form Ediswan (which later became the thorn Light Company), and eventually Edison acquired all the interests of Swan in the company.In 1910, William David Coolidge invented a way to make the tungsten wire more efficient, making the bulb more cost-effective.From 1913 to 1930, innovators turned their attention to the use of inert gases in bulbs to further improve efficiency.In 1930, Imre Brody decided to mix Krypton with xenon gas and reduce costs, and also developed a method to capture Krypton from the air at the factory in Ajka, Hungary.The latest major development in the lighting industry is the introduction of energy-saving bulbs or compact fluorescent bulbs.Although they were considered a relatively modern invention, the CFLs were originally conceived by Pete Cooper in the 1980 s and originally used in the photography industry.The first practical fluorescent lamp was designed by GE\'s George Inman and became the blueprint for the modern CFL invented by Ed Hammer and GE in response to the 1973 oil crisis.Although the design meets all its requirements, it has never been manufactured on a large scale due to the cost of mass production, but the design is subsequently leaked and copied.The steady growth in CFL production has continued until today, but consumption is expected to increase significantly as inefficient incandescent lamps are phased out.By September 2012, there will be no incandescent lamps to reduce carbon emissions and energy costs.So what is the future of electrical lighting?Many people think the answer is LED bulbs.Led was originally used for devices such as alpha digital display and pocket calculator, and has recently been successfully applied in commercial and home lighting.As long as incandescent lamps and state-of-the-art bulbs produce high-light output and consume a small amount of energy at the same time, the led can last up to 50,000 times.Although the initial lighting cost is high, the bulbs will pay more for themselves in their lifetime.LED bulbs with fast on/off times, able to withstand high frequency cycles, are ideal for car headlights, dramatic spotlights, traffic lights and dynamic road signs, as well as home and home lighting.
