Construction and operation of gas discharge lamps



Impulse high voltage (AC voltage of around 25 000) from the control unit of the discharge lamp is applied between the terminals of its lamps, initiating the gas discharge in xenon, which is filled with light.
When excited by the xenon gas discharge lamp temperature inside the lamp rises, vaporizing the mercury and an electric arc.
Mercury and the electric arc causes a further increase in the temperature inside the lamp iodide vaporizes and decomposes, the atoms of the metal given stored energy, producing light.
