The reason why xenon headlights change from white to yellow light?
1 Answers
Xenon headlights have a limited service life. As the usage time increases, the color temperature drops below 5000K, causing the xenon headlight color to change from white to yellow, indicating that the xenon bulb should be replaced at this time. Below is relevant information: 1. Working principle of xenon headlights: Xenon headlights refer to high-intensity discharge (HID) lamps. Xenon headlights work by filling an ultraviolet-resistant quartz glass tube with various chemical gases, such as xenon and other inert gases, and using a booster to instantly increase the vehicle's 12-volt power supply to 23,000 volts. Under high voltage, xenon gas is ionized and produces a light source between the two electrodes. 2. Characteristics of xenon headlights: Xenon headlights have features such as strong energy-saving capability and good color temperature. Compared to ordinary bulbs, xenon bulbs have three times the luminous intensity of standard halogen bulbs while consuming only two-thirds of the energy. Additionally, xenon bulbs use a light color nearly identical to daylight, creating better visual conditions for drivers and improving driving safety and comfort.
