The winter approaches, because some vehicle owners the headlight
has entered the mist, has this kind of situation the new car majority,
therefore many vehicle owners start to suspicion that headlight's quality, listens to our view and the suggestion regarding this.
1.The temperature difference change causes the headlight to enter the mist.
On the headlamp's top plate has a plastic ventilation channel, the heat
expansion gas discharges through this channel, sometimes will have some
moisture to enter the air vent, will have the slight haze phenomenon.
This kind because of temperature difference change, but the haze situation occurs much in the winter, the rainy season or foggy day's time. Present's automobile headlight, to pursue the better illuminating effect, mostly uses the lens type, this kind of lamp optical fiber is more centralized, but the headlamp mirror surface only then the small region is heated up, the moisture mainly gathers in the light area flank mirror surface, therefore was discovered quite easily. In the lamp enters the mist, the vehicle owner do not be startled, in the ordinary circumstances, will not affect headlight's normal use, also will not be the unnecessary replace headlight.
2.When wash the car, easy to enter the mist.
When clean automobile interior should use the towel, or flushes out the engine with the compressed air, but cannot use the water torch to flush directly.
If the vehicle owner often uses in the water torch flushing automobile headlight or the vehicle, very easy to cause the water drop inflow air vent, in the headlight easy to present the mist. In addition, the frequency fords the deep water, also easy to cause the headlight to produce the mist, for instance the automatic pilot tours the amateur to like driving fords the deep water, or the vehicle owner meets the rainstorm weather, can not but let like the vehicle fording.
Usually in situation, water depth, once surpasses the wheel, will enter the headlight from the air vent. Especially the great rainy day is easiest to cause the head lamp headlamp to enter the water, but after the head lamp headlamp enters the water, brightness will also come under the influence, if will enter the water many also possibly to damage the head lamp headlamp. Therefore reminder vehicle owner, after rainy day driving, might as well many inspects the headlight, if discovered that in the headlight the mist are excessively many, and has this kind of situation repeatedly, should promptly to the service shop .ĦĦ
3.Simple operation elimination lamp mist.
In ordinary circumstances, if the vehicle owner meets in the headlight to have the mist, should first analyze the reason which the mist appears, if because of the temperature difference or the moisture result, for instance the use headlight time is excessively long, after getting off work goes home, to turn off the lights directly, second day of early morning discovered that in the headlight has the mist. So long as the vehicle owner turns on the head lamp headlamp and the headlights on full beam, in 10~20 minute later headlight's mist start to vanish slowly. But the vehicle owner was sure to remember that should better not let the headlight carry on the high temperature roasting, because headlight's material is the plastic material quality generally,
if the roasting hyperpyrexia, will have the possibility to create the headlight semblance conditioning distortion very much.
Moreover, present's headlight is generally the integral type, after transparent chimney, will also stick has a protection lamp body's back board, the high temperature roasting will also cause between the two's agglutination sol to melt, increases the headlight to enter the water the possibility. Generally speaking, in headlight's moisture
content will be using the headlight or under normally the sunlight illumination will evaporate very quickly vanishing, if your headlight will present the water phenomenon frequently, must arrive at the service shop to inspect the lamp body.ĦĦĦĦOr fords into the deep water because after the car wash creates the mist entry, then must certainly
after washing the vehicle or fords inspects the headlight immediately, looked whether to have enters the mist the phenomenon, if discovers has the mist, then lightens the headlight, evaporates the mist, but does not want in the long time neglect lamp the mist condition. Usually in situation, if in the headlight enters excessively many mist, and has this kind of situation repeatedly, means that the headlight dust cover has the possibility dehiscence, causes the water to enter the headlight, forms the mist in the chimney. But after the headlight enters the water, brightness will also come under certain influence, simultaneously will also have the possibility to cause the electric circuit plug to corrode, also will cause the headlight to create certain damage.
After therefore the vehicle owner wants certainly to foster the rainy day travel, inspects the headlight situation the custom.
