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.

2021年1月23日 · In a discharge lamp, light is emitted when the electrons collided with each other. The gas is maintained at low pressure and to ionize the gasses we need high voltage. When the high voltage is provided to the gas tube, the gasses inside the gas tube are ionized.

2025年1月13日 · A discharge lamp is a type of light source that generates light by passing an electric current through a gas or a mixture of gases. When the gas is energized by the electric current, it produces visible or ultraviolet light through a process called gas discharge.

The Discharge lamps are one of the reliable sources of artificial light energy, which fundamentally works by converting electrical energy to light energy by ionizing the gas particles. Discharge lamp gained popularity, in the mid-twentieth century.

2024年2月27日 · Discharge lamps, mainly fluorescent lamps, incorporate small quantities of mercury, posing environmental issues if not well disposed of. It is important to follow right recycling and disposal tactics to reduce environmental impact.

2020年9月16日 · Discharge lamps come under the classification of artificial light sources that produce light by transmitting an electrical discharge via ionized gaseous substances. Usually, those lamps make use of either xenon, argon, krypton, neon, or a combination of these gases.

High-intensity discharge lamps are a type of arc lamp. Brand new high-intensity discharge lamps make more visible light per unit of electric power consumed than fluorescent and incandescent lamps, since a greater proportion of their radiation is visible light in contrast to infrared.

Discharge lamps are of two types: Those which give the light of the same colour as produced by the discharge through the gas or vapour such as sodium vapour, mercury vapour and neon gas lamps. Those which use the phenomenon of fluorescence and are known as fluorescent lamps.

2022年4月4日 · A lighting device consisting of a transparent container within which a gas is energized by applying an electric voltage and thereby made to glow is known as electric discharge lamp. The electric discharge lamp is also known as vapor lamp or gas-discharge lamp.

2023年9月19日 · A discharge lamp is a type of light source that’s made up of a glass or quartz tube containing a specific gas and often a metal vapor. When electricity flows through this gas and vapor mixture, it creates light or ultraviolet radiation.
