Since ancient times, “finishing touches”, which are now often deplored the “eyes are the windows of the soul,” the saying goes, ah ogle. As a car mechanic art It’s headlights in the eyes of those cars have wonderful projects as a general lover, it is also a natural high level of concern.
The car headlights, the headlights, it is called a formal point of view. No doubt, it is estimated that for Highway Safety The importance of Guer, all vehicles will become “standard.” And as people car-dependent growth and a gradual improvement in the individual needs of the automotive performance and appearance of the floodlights come to be recognized more and more.
However, the specific structure of the headlights of their car, estimate how many people would not erase. Many friends think it is also possible that a flashlight Bale expanded. However, this “large flashlight” how a car on the hundreds of thousands on the outside? It really is a profiteer in the “black” us?
In fact, the lights of today, it has the technical content is high. To improve night driving and adverse weather conditions of security, the requirements of the projector is very high. Not only to illuminate the far illuminate the wide, they have yet to clear. This makes the design and manufacture of headlights complex, naturally leads to higher costs. Xiao Bian
considers such a long article, it should gentlemen structure and evolution of the headlights was some interest. Then we learn about “eyes” of vehicles? Headlights.
modern highways and high traffic levels to strictly limit the use of headlights. In most classic cases, almost alone, the lamp real line. Therefore, improving basic accent light on recent improvements in optical properties. Such as:
? Near the introduction of the bare non-symmetrical shape, characterized by the formation of the extension along the road on the horizon right (RHD);
? Officially approved for use in all kinds of halogen lamps, which can improve the illumination of the road on a 50% to 80%;
? With a complex geometry using a modified system of projectors (PES, HNS, PD2), improve the lighting efficiency of 50%;
? “Litronic” gas discharge headlamps (with light emission in the arc), produced by the illumination of more than twice the size of halogen lamps.
projector light distribution in their need for light / dark cutoff line. This line of general cut of the reflector, a shade or screen to produce a special filament reflective. This line provides the dark on / the form in distribution, in all driving conditions are acceptable horizon. This provision allows the maintenance of vehicles approaching each other at reasonable limits glare, while at the same time in areas of light / darkness below the very high luminosity cutoff.
Templates light distribution needs to find the maximum unity of vision and minimal glare. At the same time to take care of vehicles on other needs of the non-integrity (eg, the headlights must be provided to assist in the corners), the distribution of light on the road should be extended along the left and right sides.
Performance evaluation and testing Automobiles projector to pass. Requirements: To ensure good visibility minimum required levels of lighting the road in order to avoid glare maximum level of illumination intensity.
