Headlamp Type

---------   [ 2015-09-18 ]

Automobile headlamps are generally incandescent, halogen, xenon and other types. With the continuous development of automobile technology in the past that a vacuum incandescent lamp has been successively eliminated. Now the car's headlights with a halogen lamp, a xenon lamp-based.
Halogen is within the lamp infiltrate a small amount of inert gas iodine evaporated tungsten atoms from the filament out of the encounter with an iodine atom reacts iodide tungsten compound, tungsten iodide compound when a white-hot filament contacting (temperatures in excess of 1450 ℃) , will decompose and the iodine is reduced to tungsten, tungsten filament back again rejoin go, iodine gas is re-entered. So endless loop, the filament is hardly blown bulb is not black, so it than the traditional incandescent headlamps longer life, greater brightness. Now cars are commonly used such headlamps.

Halogen light has its unique structure, there are two sets of lights within each filament, a group of the main beam filament,,the light emitted by the rear mirror reflection shade shot to go straight ahead, which is what we usually say sources "beam." Another is the partial beam filament, the light shielding plate toblock to shade the upper half of the reflective mirror emitted light is reflected off its diffuse down to the ground, not to oncoming drivers causing dazzle This light is what we usually call "beam."

Xenon lamp, the English abbreviation is HID. It emitted light luminance is twice the normal halogen lamps, and energy consumption is only two thirds of its life of up to ten times the normal halogen lamps. Xenon lights greatly increases driving safety and comfort, but also help relieve stress and fatigue that people driving at night. Motorists can be found in the first time the danger, so as to obtain a sufficient reaction time, to a large extent reduce the rate of accidents at night. At present, the launch of new luxury Audi, Passat, Buick Regal, Mazda equipped with xenon headlamps. From a market point of view, xenon headlamps will become the mainstream market.

Halogen headlights using traditional use of "light-emitting combustion" method produces lighting, and "HID" is the use of "jump-in-emitting" to illuminate. The former is like barbecue, light coals issued; and the light on the plant when the latter is similar to the site welding issued, two of which relatively light on? You may wish to compare the actual observation. According to th experimental data show that the "HID" is three times the brightness of conventional light-emitting headlights, irradiation distance was twice that of conventional headlights.
