The first headlights dimming, so the car some dazzling To overcome this drawback, and later use the additional brightness adjustment. The headlights can be moved in the vertical direction, but the driver must move the fixture off the mobile device. In 1925, the navigation company to promote a dual filament bulb, low beam adjustment switch on the steering column control.

Headlights ordinary incandescent lamps, halogen lamps, xenon type. With the continuous development of automotive technology, in the past the kind of vacuum incandescent lamp has been eliminated. The automotive headlamp of a halogen lamp, a xenon lamp.
That is, the halogen lamp, bulb infiltration of small amounts of an inert gas, iodine, evaporated tungsten the filament atom and an iodine atom, a tungsten compound iodide iodide, tungsten compound, contact heating filament (temperature satisfy the reaction of more than 1450 ? C. ) back to the filament will also decomposition and reduction of tungsten and iodine, tungsten Add again to re-enter, and iodine gas.


Endless loop, the filament almost not blown, the bulbs also not black, longer life than traditional incandescent headlamp, the greater brightness. Cars this headlamp.

Halogen lamps, unique light distribution structure, each lamp has two sets of filaments, a group of the main beam filament, the mirror reflection of the light emitted by the lamp shade straight forward shot the light source is commonly referred to as "beam". Another partial beam filament, the upper portion of the light emitted by the light-shielding plate blocks reflector lamp shade, the light is reflected down to the ground diffusion blinding is not caused to the driver of the oncoming vehicle, such a light source is usually say " near the light.

HID xenon lamp abbreviation.
