1. Headlamp Type Type
Automotive headlamps are generally incandescent, halogen, xenon and the like. With the continuous development of automobile technology in the past that a vacuum incandescent lamp has already been eliminated. Now the car headlight halogen lamp, a xenon lamp oriented.
Halogen is penetration of a small amount of an inert gas within the bulb iodine, the reaction from the filament meets evaporated tungsten atoms and an iodine atom, generating iodide tungsten compounds, when the iodinated compound a tungsten filament contacting intense (the temperature exceeds 1450 deg.] C), will decompose and the iodine is reduced to tungsten, tungsten filament again back to rejoin, iodine gas is re-entered. And so on incessantly, barely blown filament, the bulb will not be black, so it is longer than the traditional incandescent headlamps life, greater brightness. Now cars are widely used headlamp.
a halogen lamp has a unique structure of the light distribution, the two inner Each light filament, a main beam filament is set, the light emitted by the shade reflecting mirror to shoot straight forward, such a light source that is, we usually say ldquo; high beam rdquo ;. Another is the partial beam filament, the light shielding plate to stop to shade the upper half mirror emitted, which light is reflected off of the ground down to the diffusion, to the driver without dazzling oncoming vehicles cause this light is what we usually call ldquo; low beam rdquo ;.
a xenon lamp, it is the English abbreviation HID. The brightness of light emitted from it is twice as common halogen lamps, and energy consumption is only two-thirds of its service life up to ten times the ordinary halogen lamps. Xenon lamps greatly increases safety and driving comfort, but also help ease the tension and people driving at night fatigue. Dangerous drivers can be found in the first time, to obtain a sufficient reaction time, significantly reduces the incidence of accidents at night. At present, the launch of the new Audi, Passat, Buick Regal, Mazda and other luxury models are equipped with Xenon headlamps. From a market point of view, xenon headlamps will become the mainstream market.
