Lamp in which the light is produced, directly or indirectly, by an electric discharge through a gas, a metal vapor, or a mixture of several gases and vapors.
Varying forms exist - the high & low pressure sodium (SON & SOX), high pressure mercury (MBF) as well as numerous variants using complex gases.
a lamp that generates light by a discharge between two electrodes in a gas
A gas filled tube that gives off light when an electric charge is passed through it. One can be found in your electronic flash.
passes a spark between two electrodes inside the glass envelope to generate light. Cannot be dimmed (in any meaningful way) electrically, and a mechanical dimmer must be used. A high voltage is needed to ionise the gas in the envelope in the first place ( striking'), whilst the voltage once the lamp has 'struck' must be carefully maintained. These functions are usually carried out by a ballast unit.
Light bulb which incorporates an electronic discharge through a gas or vapor
A lamp in which light (or radiant energy near the visible spectrum) is especially produced by the passage of an electric current through a vapor and a gas.
A lamp that produces light by discharging an electric arc through a mixture of gases and gaseous metals.
light source that provides illumination when an electrical charge is applied to gas particles in a glass tube. An example of this device is electronic flash.
Discharge lamps are a type of light bulb that includes a discharge chamber with a discharge gas. The discharge gas responds to an arc or electron flow to create radiation. The walls of the discharge vessel may respond to the radiation of the gas to produce visible light.
