HID Xenon bulb refers to a high-pressure gas discharge lamp that is filled with an inert gas mixture including xenon gas and has no filament that halogen lamps have. Xenon lamps for lamps and outdoor lighting. HID Xenon bulbs are also called HID gas discharge headlamps in the field of automotive lamps. It replaces the traditional tungsten wire with high-pressure xenon gas wrapped in a quartz tube to provide higher color temperature and more concentrated lighting. Since the xenon lamp is a beam of arc light formed by activating xenon gas with high voltage current, it can continuously discharge and emit light between the two electrodes. The power of ordinary car tungsten bulbs reaches 55 watts, while the xenon lamps only need 35 watts, which is reduced by nearly half. Xenon lamps significantly reduce the load on the vehicle's electrical system. The color temperature of car xenon lamps is between 4000K and 6000K, which is much higher than that of ordinary car headlight bulbs. It has high brightness. The light color of the 4300K xenon lamp is white and yellowish. Due to the lower color temperature, the visual effect is yellowish, and the penetrating power of the light is stronger than that of the high color temperature lamp, which can improve the driving safety at night and in foggy weather. It was first used in air transport. There are two categories of xenon lamps that are widely used in the market, one is automotive lighting and the other is motorcycle lighting. But it has been more than ten years since it was used in cars in large quantities. It was developed by HELLA in the early 1990s. Xenon lamps are more expensive than ordinary halogen lamps and incandescent lamps due to their high technical content.
