Abstract
With the rapid development of modern transportation, the automobile has become one of
the most important traffic tool for people to travel. In our country,the automobile has quickly
entered the ordinary family. Followed by the traffic accidents caused by vehicles are on the rise,
so reduce the rate of accidentsbrook no delay. The car when driving at night, the improper use of
switching car headlights far and near light will also bring some unsafe factors to the
driver.Provisions of the relevant provisions of the law on road traffic safety in China, the car is
running at night when two vehicles meet, should be adjusted to near lightheadlamp high beam,
return again after the meeting. Now for the convertible carheadlight headlight control problems,
most manufacturers use allows the driver tomanually convert, this manual device in the
modernization of today, there is obviously a little behind, on the other hand, when the switching
operation of far and near light is completely rely on the driver's accomplishment and the degree
of attention to its own security, it will also bring some hidden dangers. Therefore,development of
vehicle headlamps far and near light automatic control device,and then try to reduce the
probability of the occurrence of the traffic accident,has important social significance and broad
prospects.
This article is about a study of automatic control device for headlight during vehicle
meeting at night. The device is composed of photosensitive sensor, SCM, relay components. The
night driving of vehicles meet meeting, intensity opposite vehicle headlamps light sensors will
monitor the meeting, reaches a certain value is automatically triggered by the high beam light
conversion for the. The device not only realizes the automatic conversion of far and near light,
low price, simple circuit, suitable for production.
