History of the Light Bulbs

History of the Light Bulb 1803 – 1809 Incandescent First Arc Lamp Is Created Find out more about the light bulb's long history. Humphry Davy demonstrated the first incandescent light to the Royal Institute in Great Britain, using a bank of batteries and two charcoal rods. Arc lamps provided many cities with their first electric streetlights. 1835 Incandescent First Constant Electric Light Is Demonstrated James Bowman Lindsay demonstrated a constant electric light at a public meeting in Scotland. Some have credited him with being the inventor of the incandescent light bulb.

Called Geissler tubes, they became the basis of many lighting technologies including fluorescent lights. Pictured here are color drawings of early Geissler tubes. Inventors all across the world -- including William Sawyer and Albon Man in the U.S. and Joseph Swan in England -- worked on creating an electric incandescent lamp. Pictured here are some early incandescent bulbs. Illustration by M. Rapine, Wikimedia Commons.

Developing a Whole Lighting System Patested Jas, 21. 180 Ne. 223,9 Edison focused on the entire lighting system, showing that it was possible to distribute electricity from a centrally located generator with the Holborn Viaduct in London and developing the first commercial power utility in lower Manhattan. In 1878, Edison and his researchers at Menlo Park turned their attention to incandescent lamps. They focused on improving the filament -- first testing carbon, then platinum, before finally returning to a carbon filament. Pictured here is Edison's 1880 patent for the 1901 Fluorescent Precursor to Fluorescent Lights incandescent bulb. Peter Cooper Hewitt created a blue- green light by passing an electric current through mercury vapor. The lights had few suitable uses because of the color but were one of the precursors to fluorescent lights.

Out with the Carbon Filament and in with the Tungsen 1908 Incandescent In 1904, incandescent lamps with tungsten filaments appear on the European market. These bulbs lasted longer, were brighter and more efficient than lamps with carbon filaments. Edison Screw Becomes Universal Part of Edison's contribution to the light bulb was the socket he developed, which today is called the Edison Screw. By 1908, it was the most commonly used light bulb socket used, and today, it is used for almost all residential Image courtesy of the National Museum of American History. lighting applications. 1913 Incandescent Doubling the Efficiency of Incandescents Photo courtesy of of @iStockphoto/TokenPhoto. Irving Langmuir discovered that filling a light bulb with inert gas like nitrogen instead of vacuuming out the air doubled the light bulb's efficiency. 1926 – 1934 Fluorescent Neon Tubes + Phosphers = Fluorescents 1939 Fluorescent By the late 1920os and early 1930s, European researchers were doing experiments with neon tubes coated with phosphors. Word of these experiments helped spark fluorescent lamp research in the Fluorescent Lamps on Display U.S. In 1939, GE and Westinghouse introduced fluorescent lamps at both 1951 Fluorescent the New York World's Fair and the Fluorescents Overtake Incandescents Golden Gate Exposition in San Francisco. By 1951, more light in the U.S. was being produced by linear fluorescent lamps than incandescent -- a change that was led by the need for efficient lighting during World War II. 1962 LED First Light Emitting Diode (LED) Is Invented 1973 Fluorescent GREEN FLAG EVERYONE WELCOME Energy is No Longer Cheap The 1973 oil crisis marked a turning point in U.S. energy consumption because energy was no longer cheap. Researchers rose to the challenge and began developing fluorescent bulbs for residential use. YELLOW FLAG While working for General Electric, Nick Holonyak, Jr., invented the first visible-spectrum LED in the form of red diodes. Pale yellow and green diodes COMMERCIAL •TRUCKS BURDEN OF PROOF • CARS ON CUSTOMER were invented next.

As researchers improved red diodes and their manufacturing, companies began incorporating them into consumer products like calculator displays and indicator lights. Photo courtesy of David R. Tribble, Wikimedia Commons. 1985 Fluorescent First CFL Hits the Market Early CFLS hit the market in the mid- 1980s and ranged from $25-$35 a bulb. 1994 LED First Blue, Then White LEDS The invention of the blue diode in the 1990s quickly led to the discovery of white LEDS. Shortly thereafter, researchers demonstrated white light using red, green and blue LEDS. 2000 LED Energy Department Works to Push LEDS Forward In 2000, the Energy Department partnered with private industry to push white LED technology forward by creating a high-efficiency packaged LED device. 2002 – 2008 LED 2008 LED First Residential LED Bulb Hits the Market Energy Department Launches L Prize Competition The L Prize Competition is designed to spur the development of ultra-efficient solid-state lighting products to replace common lighting technologies. By 2008, there were just a few LED replacement bulbs on the market, and most were 25-40 watt equivalents. 2011 LED Philips Wins L Prize 60-Watt Replacement Category 2012 LED 49 Million LED Products Installed After a rigorous review process, the Energy Department announces that Philips' entry in the 60-watt replacement category has met all performance requirements and declares it the winner of that category. In 2012 alone, more than 49 million LED products were installed in the U.S., saving about $675 million in annual energy costs. PHILIPS 2013 Fluorescent CFLS for as Little as $1.74 Deployment and Cost for LED Lights Installed 2008-2012 Nearly 30 years after CFLS were first introduced on the market, their costs have dropped to as low as $1.74 a bulb. They also use about 75 percent less energy than incandescents and last about 10 times longer. energy 2013 LED LED Costs Drop Dramatically I US. LED LIGHTING, ATYPE LAMP S/KILOLUMEN - US. LED LIGHTING, LED A-TYPE LAMPS INSTALLED Since 2008, the cost of LED bulbs has fallen more than 85 percent, and most recently, a number of retailers announced that they will be selling LEDS at $10 or less. 10 2014 LED Future of LED Lighting In the future, we have the potential for even greater savings by designing LED lighting systems to take full advantage of LED's strengths rather than forcing LEDS into 19th century fixtures.
