Xenon lamp (High intensity Discharge Lamp), also called HID gas discharge headlamp in the field of automotive lamps, fills the inside of the bulb with high-pressure xenon gas to replace the traditional tungsten filament. The principle is to use high-voltage current to activate xenon gas to form a beam of arc light, which continuously discharges and emits light between two electrodes. It can provide higher color temperature and more concentrated lighting.
Xenon lamps consume less power than traditional tungsten lamps, which can significantly reduce the burden on the vehicle's electrical system. Since xenon lamps do not have filaments, they will not be scrapped due to broken filaments, and have a longer service life than halogen lamps. There are many, which can meet the entire life cycle of a car.
The luminous flux emitted by xenon lamps is more than twice that of halogen lamps. At the same time, the efficiency of converting electrical energy into light energy is more than 70% higher than that of halogen lamps, so xenon lamps have relatively high energy density and light intensity. The increased brightness of car lights also effectively expands the visual range in front of the car, thereby creating safer driving conditions.
