The Eyes Of The Automotive Vehicle Headlights Do Ct Depth Analysis - Automotive Industry-hc360 Hc
Since ancient times, "finishing touch", which now it is often lamented the "eyes are the windows of the soul," the saying goes, ogle ah
. As a mechanical art Car It's headlights in the eyes of car people have wonderful projects like a lover's general, natural it is also a high degree of concern.Car headlights, headlight, it is called a formal point. No one doubts it is estimated that for Road safety The importance of Guer it will become all vehicles "standard." And as people car-dependent growth and gradual improvement in the individual requirements of the automobile, the performance and appearance of the headlamps come to be recognized more and more.
However, the headlights of their car's specific structure, estimate how many people would not clear. Many friends think it is also possible that a enlarged flashlight Bale. However, this "large flashlight" how a used car on the hundreds of thousands out? It really is a profiteer in the "black" us?
In fact, today's headlamps, it has the technical content is high. In order to improve night driving and adverse weather conditions the safety, the requirements of the headlight is very high. Not only to illuminate the far illuminate the wide, they still have to clear. This makes the headlight design and manufacture of complex, naturally led to rising costs. Xiao Bian
estimated that such a long article, it should gentlemen structure and development of the headlights had some interest in it. Then we find out more about "vehicle eyes"?? Headlights.
Modern highways and high traffic density strictly limit the use of beam headlamps. In most standard cases, almost alone, the actual line Lamp . Therefore, improvement of basic focus headlight on recent improvements in the optical properties. Such as:
?? Nearly bare introduction of non-symmetrical shape, characterized by the formation of extension along the road on the right horizon (right-hand drive);
?? Officially approved for use in all kinds of halogen lamps, which can enhance the illumination of the road on the 50% to 80%;
?? With complex geometry using a modified headlamp system (PES, HNS, PD2), improve the lighting efficiency of up to 50%;
?? "Litronic" gas discharge headlamps (with light-emitting arc), produced by the illumination of more than twice the size of halogen lamps.
Beam headlamp light distribution in their need to have clear / dark cut-off line. This cut-off line generally reflector, shade screen or produce a special reflective filament. This line provides the dark on / out the form under the distribution, in all driving conditions are acceptable horizon. This arrangement makes the maintenance of vehicles approaching each other at reasonable limits glare, while at the same time in the light / dark regions below the cut-off very high brightness.
Light distribution patterns must find the maximum unity of vision and minimal glare. At the same time to take care of the vehicles traveling on other needs of non-integrity (eg: headlights must be provided at the corners to help), that the light distribution pattern over the road must be extended to the edge of left and right sides.
Automobile headlamp performance evaluation and testing to go through. Requirements: To ensure adequate visibility of the required minimum road lighting levels; in order to prevent dazzling illumination intensity level maximum.
