Audi new A8 car headlights using Osram LED light source

In the new Audi (Audi) A8 car, low beam and high beam and other specific lighting function, use OSRAM Opto Semiconductors (OSRAM OS) of the light emitting diode. In addition to high efficiency, long life is another advantage of LED, its life even longer than the vehicle itself. At the same time, due to the LED light and sunlight is similar, but also to improve driver safety.

Audi's latest car has an amazing feature, that is, the headlights installed in the LED daylight lamp. At the top A8 the latest vehicle models, OSRAM LED is responsible for the headlights of the lighting function in addition to more energy-saving LED beam lights and high beam headlights using OSTAR platform products, special lighting functions such as highway headlights, turn signals and all-weather lights all use LED. Its technology has significant progress, in front of the lamp to see individual light source, can easily distinguish the difference between Audi and other cars when driving at night.

Knittl, director of the LED division of OSRAM semiconductor, Germany's Peter headquarters, said, "LED has been out of the limited edition and luxury car niche market and successfully entered the production phase. LED can meet all the requirements of the new automobile lighting, and set new standards in many ways, in line with the needs of the mass market. "

Replacement cost reduction of automotive lighting

For Audi and other car manufacturers, LED has a better advantage than the traditional lighting program. The energy efficiency of LED has great energy saving effect, which is ultimately reflected in fuel consumption and carbon dioxide emissions. In addition, they also have the advantages of service life and vehicle LED scheme was equal in maintenance, so there is no need to change the light bulb, for the owners to save costs equal to.

Using diodes can also improve driver safety. Installed on the A8 OSTAR headlights with excellent clarity to illuminate the road, no glare and produce similar to sunlight, can enhance the perception of contrast. In particular, the perception of the surrounding visual field, that is, the sudden emergence of pedestrians at night, animals or dim light vehicles, white LED light energy is easier to identify such objects. Even the potholes and obstacles and old road markings, with characteristics of LED lighting can also see more clearly. Its color temperature close to daylight is another advantage, the driver's eyes are not easy to feel tired. Basically, this technology can help prevent a variety of accidents at night.

Future vehicle lighting

OSTAR headlights is a new product platform, up to 5 LED chips. The transformation process can produce the most seamless white light effect. The typical brightness value of each LED chip in 700mA is 160 lm. Depending on the variation and operating current, the brightness value can be reached between 125 LM and 1100 lm. OSTAR can adjust the brightness of headlights, headlight completely with all functions, such as high beam and low beam, turn lights, fog lights, even for lamp.

LED technology makes these things possible: for example, the use of traditional light bulbs to turn the lights need to use the complex mechanism of the actuator can be replaced by the appropriate arrangement of LED. As a result, the head lamp evolved from a mechanical component into an electronic module, which can be connected by the electronic system of the vehicle. In the case of an innovative, non glare high beam, the data of the navigation system can be combined with the information of a light based driver assistance system. Thus, the lighting system itself can only turn on the necessary road when turning or facing oncoming vehicles. LED array will play a special role in the future - depending on the lighting function can be turned on or off the individual LED pixels, can be adjusted to the most suitable for a variety of lighting.
