What are the components of xenon headlights?

[MacHenry]

Xenon headlights consist of: 1. Bulb: No filament is used; instead, brightness is generated by the collision of xenon molecules through current between electrodes; 2. Electronic ballast: Utilizes the 12V DC voltage from the battery to produce ignition high voltage for lighting the bulb; 3. Wire control box: Made of flame-retardant materials, it enhances current capacity by increasing the cross-sectional area of power wires. Xenon headlights refer to lamps filled with a mixture of inert gases including xenon, also known as metal halide lamps or xenon lamps, categorized into automotive xenon headlights and outdoor lighting xenon lamps. The working principle of xenon headlights is: 1. Inside an anti-UV crystal quartz glass tube, various chemical gases are filled, and then the vehicle's 12V DC voltage is instantly boosted to 23,000 volts by a booster; 2. High-voltage amplitude excites the free electrons of xenon inside the quartz tube, generating a light source between the two electrodes.
