What is the Difference Between Xenon Headlights and Halogen Headlights?

[DeChloe]

Xenon headlights and halogen headlights differ in their structure: Xenon headlights do not have filaments; instead, they generate light through an arc produced between two electrodes. Halogen headlights have filaments and produce light via tungsten filaments. The principle of xenon headlights involves filling an ultraviolet-resistant quartz glass tube with various chemical gases, then using a booster to instantly increase the vehicle's 12-volt power supply to 23,000 volts. Under this high voltage, xenon gas is ionized, creating a light source between the two electrodes. The principle of halogen headlights involves injecting halogen gases such as iodine or bromine into the bulb. At high temperatures, the sublimated tungsten filament reacts chemically with the halogen, and upon cooling, the tungsten re-solidifies on the filament, forming a balanced cycle that prevents the filament from breaking prematurely.
