Car lighting system is currently undergoing major changes, HID and LED light source not only got a wider range of applications, and automotive lighting system is becoming more and more intelligent.And extends the scope of intelligent, car makers are using more secure, more environmental protection, the design is more exquisite and more province oil advantages to attract users.At the same time, the new car models must also comply with the provisions of the latest, this leads to the new technology are applied.
In the lamps and lanterns of sedan, in addition to the license plate lamp, main effect is to provide drivers with road lighting, in certain circumstances can also plays a role of signal, such as overtaking was shining headlight to notice to the other party.Signal is for the convenience of other motorists to identify default profile and judge default of trends.The turn signals and brake lights is an important signal lamp, it is very important for car safety.In order to further enhance security, in recent years, widely used in cars, deputy brake lights - high brake lights, placed in the archives of the wind window position to attract the attention of others.
Car lighting system is one of the three major security a car, is the main active safety device.Such as car headlights, it is one of the important parts, ensure the safety work of car headlamps lamp as the farther the distance, the light distribution features, the better, the higher the security performance of the car.Due to automotive lighting are key components of train operation safety, therefore, the outside lights and outside lights, belong to a mandatory inspection of the project.Given the light plays an important role for car safety, all countries have strict regulations.To change the traditional way of light, the first to study law problems.Therefore, Europe has organized manufacturers (such as BMW, the Louvre, Benz, vw/audi, ford, Volvo, Renault, Peugeot, Citroen), system supplier and manufacturer of lamps and lanterns of lamps and lanterns to join the working group, to carry out research in order to make on the lighting design can have greater freedom, gradually to adapt to the light, and put forward the suggestion that the new regulations.
Car makers are using more secure, more environmental protection, the design is more exquisite and more province oil advantages to attract users.At the same time, the new car models must also comply with the provisions of the latest, this leads to the new technology are applied.
Car lighting system is currently undergoing major changes, HID and LED light source not only got a wider range of applications, and automotive lighting system is becoming more and more intelligent, and extends the scope of intelligent.Such as headlights even can transform any Angle, so that the driver see the corners, but it also depends on the car's speed.In addition, car interior lighting system also has an important impact on the environment inside the car, design engineers is trying to make this system can be integrated with the internal environment more.With the development of automobile technology, cars headlamps changing more and more.In modern cars, the past can be loading and unloading of the incandescent light bulb and incandescent vacuum headlamps has to be eliminated, instead, the halogen headlamps, its time and spread to the world, in recent years become a main force of car headlamps.At present, many manufacturers have developed a variety of different samples are tested, and some intelligent type headlamps have been put on the latest prototype.
Active rotation head lamp
In the next few years we can see the Audi advanced headlights lighting system, from top to bottom: corner lamp lighting system and steering lock and speed input response;Headlights rotation;Headlight beam shape changes along with the change of the surrounding environment.
In fact, part of Citroen models has been used as early as a few years ago the rotating head lamp, but the technology is not widely popular.But now the active rotation head lamp were again, and will has a better application than ever before.
The Audi advanced head lamp lighting system (AFS) application in the car was high hopes.In fact, the technology of the most basic lighting system (corner lamp lighting system) has been used in the Audi A8 luxury cars and other vehicles.But mentioned this kind system is more interesting is: before they even in the car began to turn can have on around the corner.
In the Audi system, side lighting mainly depends on steering Angle, however, it also related to the speed of the car.For example, when the car on the highway and the city, when the corresponding input signal into the system (GPS), headlights automatically change the beam width, Angle and range.Almost all the luxury car sales in the assembly with a GPS navigation system, so the system is feasible, and the safety performance of the system is significant.
Traditional dipped headlights when a corner in the radius of curvature is 190 m, the traditional low beam lights can provide illumination range only 30 m, and the system can reach 55 m. active lighting system for HID lighting technology has been widely used for Mercedes cars.Independent microcontroller, by processing from the sensors in the steering Angle and speed of real-time information, control the motor rotation corresponding headlights.In addition, the traditional active headlight can be used to reduce glare on the driver.
BMW lighting system
BMW pixels lighting system, this is the German carmaker recently started to study technology, the so-called "pixelheadlights" system, it adopts 480000 independent control of microscope to replace the traditional launch mirror function.This kind of method to form the headlight beams shape completely conforms to the driver's driving condition, at the same time also won't produce dazzling in the lighting.And in turn, cities, highways and unique lighting effect when it is bad weather, in addition, its subsidiary light can also illuminates the road sign.
BMW Pixel light headlight system can give the driver provides special tips, warning information, such as a left turn when the light beam shows the corresponding information left arrow.
Headlamps headlamps and intellectualization
LED headlamps, the north American international auto show debut ford concept car, the one will combine environmental protection science and technology, using solar energy as power source of lighting system, gathering energy when the sunshine in the daytime, storing, night can provide lighting is used;Another concept car USES light emitting diode LED to replace traditional light bulb, because the LED has high brightness, the advantages of short reaction time and long service life.Normally applied in the tail lights, LED the ford engineers apply this technology skillfully to car headlights.2007 Lincoln Aviator will also use the new lighting system, comprehensive all foreseeable future ford's cars to use this head lamp lighting system is possible.Ford will be the first to the LED placement head lamp design and the actual production of the depot.In the new lighting system, in addition to AFS applied to active steering lighting system, and combining with the LED light source, advocate the lamp still adopts the traditional halogen bulbs, have high brightness light source but the but again not HID the dazzle eye doubts, plus auxiliary LED lighting, the vehicle can have a full range of lighting.
Intelligent system: headlamps Hella integration in the use of high pressure gas discharge bi-xenon headlamps batch production has been mature.On this basis, the company developed new dynamic turn lights.Dynamic cornering light is an important part of intelligent headlamp system, the new technology greatly improve the driving safety and comfort.The characteristics of the dynamic cornering light is under the different turning radius, the headlamps can in horizontal swing within plus or minus 150 degrees, which makes the low beam lights to illuminate the turn area expanded almost doubled, to help the driver to turn better and faster to adapt to the road.When the turning radius is 190 m, ordinary headlamps can light up the front corner about 30 m, and dynamic cornering light illuminates the bend area can be extended for another 25 m or so.High beam in activation function, dynamic cornering light also play a role.
The traditional there are two groups of filament headlamps, penetrate far and near the beam respectively.Far brighter light beam, according to further apart, it is mainly used for high speed;Nearly dark, light beam according to get closer, it is mainly used for passing.When to use far lamp or near lamp was monopolized by the drivers, and headlamps beam intensity in each group is not adjustable, Angle is adjusted in the process of installation.
