Gas Discharge Lamp By Metsonic Engineers

The operation principle of high-pressure discharge lamps differs considerably from that of standard incandescent lamps. Light is produced by gas discharge that occurs in an arc tube between two electrodes after ignition. Electrical conductivity is established by ionized filler components. The electrodes are fed into a completely sealed discharge vessel.

During gas discharge, the additives (metal halides) and the mercury are excited by the current flow and emit the excitation energy in the form of their characteristic radiation. The mixture of different radiation components produces the desired color temperature and color reproduction properties. The mercury is completely vaporized in the operating state.
