According to the authoritative definition of car2100, High Intensity Discharge is a high-pressure gas discharge lamp in which the interior is filled with an inert gas mixture including xenon gas, and there is no filament of a halogen lamp (HID xenon lamp for short). For heavy metal or xenon lamps, the principle of light emission is through the starter and the electronic ballast, forming an arc between two electrodes and emitting light.
The principle of Xenon lamp illumination is to fill in a variety of chemical gases in a UV-cut UV-resistant quartz glass tube, most of which are Xenon, iodide, etc., and then pass through the supercharger (Ballast). The DC voltage at 12 volts is instantaneously boosted to a voltage of 23,000 volts, and the electrons in the xenon gas in the quartz tube are excited by the high voltage amplitude to generate a light source between the two electrodes, which is called a gas discharge. The white super-arc light produced by the helium gas can increase the color temperature of the light. Similar to the sun's rays in the daytime, the HID needs only 3.5A of current to operate and its brightness is three times that of the traditional halogen bulb. Halogen bulbs are 10 times longer.
