What does car xenon headlight mean?
1 Answers
Car xenon headlight refers to a high-pressure gas discharge lamp filled with a mixture of inert gases including xenon, without the filament found in halogen lamps. Xenon headlights are categorized into those for automotive use and those for outdoor lighting. In the field of automotive lighting, xenon headlights are also known as HID (High-Intensity Discharge) headlights, which 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 discharge and emit light between two electrodes. Xenon headlights can reduce the burden on the vehicle's electrical system. The color temperature of automotive xenon headlights ranges between 4000K and 6000K. A 4300K xenon headlight emits a white light with a yellowish tint. Due to its lower color temperature, the visual effect appears more yellowish, and its light penetration is stronger than that of higher color temperature lamps, thereby enhancing driving safety during nighttime and foggy conditions.
