HID lamps (HID)
HID is High intensity Discharge HID abbreviation, can be called heavy metal lamps or Xenon lamps. Its principle is anti-ultraviolet radiation in the UV-cut crystal quartz glass tube, filled with a variety of chemical gases, a majority of whom, such as Xenon with iodide and an inert gas, and then through the supercharger (Ballast) the car 12 volt DC voltage instantaneously pressurized to 23,000 volts of electricity through high voltage amplitude excitation of xenon gas inside the quartz tube electronics free, light between two electrodes, which is called the gas discharge.
