2. Plasma lamp - Wikipedia

   en.wikipedia.org/wiki/Plasma_lamp

   A plasma lamp. Plasma lamps are a type of electrodeless gas-discharge lamp energized by radio frequency (RF) power. They are distinct from the novelty plasma lamps that were popular in the 1980s. The internal-electrodeless lamp was invented by Nikola Tesla after his experimentation with high-frequency currents in evacuated glass tubes for the ...

   en.wikipedia.org/wiki/Electric_Lighting_Acts...

   The Electric Lighting Acts 1882 to 1909 [1] are acts of the Parliament of the United Kingdom . They comprise four public general acts: the Electric Lighting Act 1882 ( 45 & 46 Vict. c. 56); the Electric Lighting Act 1888 ( 51 & 52 Vict. c. 12); the Electric Lighting (Clauses) Act 1899 ( 62 & 63 Vict. c. 19); and.

4. Induction lamp - Wikipedia

   en.wikipedia.org/wiki/Induction_lamp

   The induction lamp, electrodeless lamp, or electrodeless induction lamp is a gas-discharge lamp in which an electric or magnetic field transfers the power required to generate light from outside the lamp envelope to the gas inside. This is in contrast to a typical gas discharge lamp that uses internal electrodes connected to the power supply by ...

6. Gas-discharge lamp - Wikipedia

   en.wikipedia.org/wiki/Gas-discharge_lamp

   Germicidal lamps are simple low-pressure mercury vapor discharges in a fused quartz envelope. 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.

7. Sodium-vapor lamp - Wikipedia

   en.wikipedia.org/wiki/Sodium-vapor_lamp

   A sodium-vapor lamp is a gas-discharge lamp that uses sodium in an excited state to produce light at a characteristic wavelength near 589 nm . Two varieties of such lamps exist: low pressure and high pressure. Low-pressure sodium lamps are highly efficient electrical light sources, but their yellow light restricts applications to outdoor ...
