Automobile lamps adaptive development and reviewed in this paper

With the development of the society and the continuous improvement of people's living standard, people on the requirements of the car has not only confined to performance, cost, but more and more requirements modern car safer, more environmental protection and more human. Car manufacturers are using more security, more environmental protection, design is more elegant and more province oil advantages to attract users. And at the same time, the new car should also must comply with the latest regulation, this has led to a new technology to get the application. As the big three auto safety thing, automobile lighting systems is one of the main active safety device, to the traditional automobile lighting system improvement and innovation also has become a hot spot in the study of the world automobile manufacturers.

Therefore, how to make automotive lighting, driving more intelligent safety, more comfortable will become a very urgent and has the important practical significance of the subject. The traditional automobile lighting system mainly by the headlamps system, lighting

system, signal car lighting system composed of three. With the progress of science and technology, traditional lighting system also experienced rapid progress, the corresponding traffic regulations also more and more perfect, headlamps system has gone through a kerosene lamp from the original to incandescent lamp, halogen lamp to now discharge lamp of the development process, the signal from the first portable lighting system development now widely applied to a kerosene lamp LED lights, the car lighting system is more and more kinds, more and more humane. But the actual use of traditional headlamps system, there are many problems. For example, the existing in the light of the close on lighting effect is very bad, especially in the urban traffic is more complex, often have a lot of drivers in the evening nearly light, and front fog lamps entirely open headlights; Vehicles in turning the corner, there are also lighting dark areas, the serious influence the driver on the corners on the judgment of the obstacles; Vehicles driving on a rainy day, the ground water reflected the headlights, produce light reflected glare, and so on. According to statistics, about 50% of the night accident happened without lighting facilities of the dark road, road lighting the poor, the greater the likelihood of accident. The night accounted for 33.1% of the total number of accidents accident (although driving at night accounts for only 1/5 of the rate during the day). The death toll is about 50%, compared to 12.4% during the day, the death rate from the accident, and the night for 33, 7%.

The night and high death rate from multiple accident, and the reason is the eyesight of the driver and the lower than about 1/2. In addition the rain and fog will also make vision loss, glass and dirty water before not only reduced vision, still can make the distance distortion, which must be the attention of the driver. European car lighting research institutions in the once a special investigation, the results showed that the most wants to improve the European drivers of the wet weather is the lighting of the water came in second, a rural road lighting, the next is in turn corners lighting, highway lighting and urban lighting. The above of these problems, make developing a DuoZhong lighting function with the lighting system become necessary, and the function of switching, for security reasons, and must be automatically, thus, adaptive lighting system (ALS) will emerge as The Times require.

At present, our country of all motor vehicle testing lines are equipped with headlamps inspection instrument, many experts and scholars are many important is also discussed in the paper. But, through the test of a station exploits the year two thousand Taiwan client survey analysis, vehicle headlamps a total qualified by only 45%, and these qualified vehicles and most of all foreign imports of the vehicle. Is Cause the situation are the main reasons: (1) the car factory products do not meet the national standards, and many of the car factory in just when examination is not qualified, headlamps But others just a factory qualified,

but can't use how long and then aging, poor durability. (2) the most vehicles have the lack of units and the unit testing conditions and means, in the headlamps for maintenance, adjust the inaccurate even will not be adjusted. (3) because some leadership and drivers are subjective safety, think in car headlamp is not safety testing is very important, as long as the car brake performance that can assure safety, so for lack of maintenance and maintenance, headlamps on schedule maintenance and replacement cannot. (4) for most of the testing station can't test results in a timely and accurate to inform owners in testing station, in the practice of the factory also cannot fundamentally solve the problem. Make a complete year after year while still driving. This is CheJian departments and testing station should be improved and self perfection in. Automobile lamps when regular testing unqualified has the following three conditions: (1) the luminous intensity enough; (2) the bad light distribution, main beam axis skewed a quantity to exceed bid; (3) above two kinds of circumstances exist. The influence factors of its own problems have vehicles, such as: battery electric power system can't deficit or charging, test power system should be in charge state; Wire corrosion; Tire pressure is insufficient; Tire model about different; Adjustment screws to adjust the improper; Glass chimney on the dirt and headlamps quality problem. Also have a plenty of testing lines light inspection instrument installation accuracy and precision is unqualified, such as: light meter guide levelness
