Xenon is a noble gas in a large atomic number elements (that is, the heavier elements), Atomic RADIUS is larger. ARC discharge, electron energy loss of elastic collisions with the gas is inversely proportional to the atomic weight of the gas, so when compared with other noble gases xenon arc discharge damage is small, high luminous efficiency. Meanwhile, low ionization potential of Xenon, discharge electrode near the voltage drop, this can extend the life of the electrodes. Due to the characteristics of the Xenon Atom structure, Spectra and issued long arc Xenon lamp is very close to the Sun, so car lamp into the Xenon gases than into any other effect, which is the biggest feature of xenon lamps.
