  2. Carbon button lamp - Wikipedia

    en.wikipedia.org/wiki/Carbon_button_lamp

    A carbon button lamp contains a small carbon sphere positioned in the center of an evacuated glass bulb. This type of lamp must be driven by high-frequency alternating current , and depends on an electric arc or perhaps a vacuum arc to produce high current around the carbon electrode.

  3. Henry Woodward (inventor) - Wikipedia

    en.wikipedia.org/wiki/Henry_Woodward_(inventor)

    On July 24, 1874, Woodward and his partner, Mathew Evans, a hotel keeper, filed a Canadian patent application on an electric light bulb. [2] [3] It was granted on August 3, 1874, as Canadian patent number 3,738. [4] Woodward was a medical student at the time. Their light bulb comprised a glass tube with a large piece of carbon connected to two ...

  4. Incandescent light bulb - Wikipedia

    en.wikipedia.org/wiki/Incandescent_light_bulb

    Less than 5% of the power consumed by a typical incandescent light bulb is converted into visible light, with most of the rest being emitted as invisible infrared radiation. [1] [78] Light bulbs are rated by their luminous efficacy, which is the ratio of the amount of visible light emitted (luminous flux) to the electrical power consumed. [79]

  5. Centennial Light - Wikipedia

    en.wikipedia.org/wiki/Centennial_Light

    The pendant light at Fire Station #6 in which the bulb is installed. The Centennial Light was originally a 60-watt bulb, but has since dimmed significantly and is now as bright as a 4-watt bulb. [7] [8] [9] The hand-blown, carbon-filament common light bulb was invented by Adolphe Chaillet, a French engineer who filed a patent for this socket ...

  6. Liter of Light - Wikipedia

    en.wikipedia.org/wiki/Liter_of_Light

    The refractive properties of water ensures that the light from the sun that reaches the inside of the bottle becomes omni-directional mimicking an electric light bulb and emitting the same amount of light as a 40–60 W incandescent bulb depending on the amount of solar insolation available. Adding bleach to the water prevents it from turning ...

  7. Edison light bulb - Wikipedia

    en.wikipedia.org/wiki/Edison_light_bulb

    Most of the bulbs in circulation are reproductions of the wound filament bulbs made popular by Edison Electric Light Company at the turn of the 20th century. They are easily identified by the long and complicated windings of their internal filaments, and by the very warm-yellow glow of the light they produce (many of the bulbs emit light at a ...

  8. Alexander Just - Wikipedia

    en.wikipedia.org/wiki/Alexander_Just

    In 1904 with Austro-Hungarian Franjo Hanaman he was the first to develop and patent an incandescent light bulb with a tungsten filament, made by extruding a paste of tungsten powder and a carbonaceous binder to produce a fine thread, then removing the carbon by heating in an atmosphere of hydrogen and water vapors. [3]

  9. Field-induced polymer electroluminescent technology - Wikipedia

    en.wikipedia.org/wiki/Field-induced_polymer...

    The lights can be shaped into many different forms, from mimicking conventional light bulbs to unusual forms such as 2-foot-by-4-foot flat sheets and straight or bent tubes. [6] The technology was developed by a team headed by Dr. David Carroll of Wake Forest University in Winston-Salem, North Carolina .
