The first artificial electric light was demonstrated during 1802 in London, by Sir Humphry Davy at the Royal Institution of Great Britain. It was the carbon arc discharge lamp, and since then the electric discharge has been intensely researched and developed for one fundamental reason - that it creates light from electricity more efficiently than any other kind of artificial light source.

Mar 20, 2011· HID lamps provide light from an electric discharge or arc and have a negative resistance characteristic that would cause them to draw excessive current leading to instant lamp destruction if operated directly from line voltage. The ballast is a power supply for arc discharge lamps.
ELECTRIC DISCHARGE LAMPS PREFACE. In the following pages an account is given of the various tt Osira " and" Osram " Electric Discharge Lamps which are now availaËle and of the equipment used to operate them. It is hoped that this technical description will assist engineers and others who use these lamps to a better understanding of what is, after all, a highly technical product.
Jul 02, 2019· Gas Discharge or Vapor Lamps . American, Peter Cooper Hewitt patented the mercury vapor lamp in 1901. This was an arc lamp that used mercury vapor enclosed in a glass bulb. Mercury vapor lamps were the forerunners to fluorescent lamps. High-pressure arc lights use a small bulb of high-pressure gas and include mercury vapor lamps, high-pressure ...
Jul 17, 2020· Electric discharge lamp, also called Vapour Lamp, lighting device consisting of a transparent container within which a gas is energized by an applied voltage and thereby made to glow. Mercury vapour in a neon lamp gives a bluish light; mercury is used also in fluorescent lamps and some ultraviolet lamps.
Gas-discharge lamps are a family of artificial light sources that generate light by sending an electric discharge through an ionized gas, a plasma.Typically, such lamps use a noble gas (argon, neon, krypton, and xenon) or a mixture of these gases.Some include additional substances, like mercury, sodium, and metal halides, which are vaporized during startup to become part of the gas mixture.
