Why does the xenon headlight of Haval F7 fog up?
1 Answers
Haval F7's xenon headlight fogging is caused by high air humidity, which leads to water vapor in the air condensing inside the headlight. This fogging phenomenon is normal under such conditions. Definition of xenon headlights: Xenon headlights, also known as HID (High-Intensity Discharge) headlights, replace traditional tungsten filaments with high-pressure xenon gas enclosed in a quartz tube, providing higher color temperature and more focused illumination. Xenon lamps use high-voltage current to activate xenon gas, creating an arc of light that continuously discharges between two electrodes. While standard car bulbs typically consume 65 watts, xenon lamps only require 35 watts, reducing power consumption by nearly half. Function of xenon headlights: Xenon headlights significantly reduce the load on a vehicle's electrical system. The color temperature of xenon lamps ranges between 4000K and 6000K, far exceeding that of standard bulbs. With high brightness, xenon lamps offer various light color options, with factory-installed versions usually at 4300K. Due to their color temperature being close to halogen lamps and their strong penetration, they enhance nighttime driving safety.
