What is the working principle of automotive xenon headlights?

[DelLilah]

Working principle: After the power is turned on, the transformer instantly boosts the 12V power supply to a high-voltage pulse exceeding 20,000 volts, activating the xenon gas in the xenon bulb to produce intense light with a color temperature ranging from 6000K to 10000K in the arc, appearing as crystal-clear white with a slight hint of purple-blue. Additional information: 1. Xenon headlights (High-intensity-Discharge-Lamp) refer to high-pressure gas discharge lamps filled with a mixture of inert gases including xenon, without the filament found in halogen lamps (halogen-lamp). They are abbreviated as HID xenon headlights and can also be called metal halide lamps or xenon lamps, categorized into automotive xenon headlights and outdoor lighting xenon headlights. 2. In the automotive lighting field, xenon headlights are also known as HID gas discharge headlights. They replace traditional tungsten filaments with high-pressure xenon gas enclosed in quartz tubes, providing higher color temperature and more focused illumination. Since xenon lamps generate an arc of light by activating xenon gas with high-voltage current, they can continuously emit light between the two electrodes.
