Audi is the first car manufacturer to recognize the potential of LED lighting technology and apply it to the automotive development process. Since the beginning of the development of LED lighting technology, Audi has been leading the development of this technology, becoming the object of imitation of many car manufacturers. LED technology has not only opened a new chapter in automotive lighting technology, but also opened a new stage for Audi designers. The beauty of science and technology, the Audi is using LED lighting technology to show you the dazzling light of technology and art after the collision.
Since the birth of the car, lighting technology has always been an important issue in driving safety. From the earliest gas lamps to xenon headlights, it has experienced the first-class incandescent lamp era and the evolving tungsten halogen lamp era for more than 100 years. Until 2003, Audi launched the PikesPeakquattro concept car, which for the first time showed the public LED lights that predicted the future of lighting technology. The global automotive media have been amazed: a new round of automotive lighting revolution has hit. In 2005, Audi introduced the world's first A8LW12 (D3) with LED daytime running lights, and gradually extended this technology to all models. Today, LED daytime running lights have become one of the distinctive logos of the Audi brand.
The aggressive Audi has not stopped here, but also introduced LED lighting technology into the field of headlight lighting. In 2006, the Audi R8 super sports car, known as the Audi brand racing history, was launched with the world's first full-LED headlights, opening a new era of automotive lighting. Three years later, the Audi brand A8 (D4), the latest flagship product that has passed on the centuries-old blood, showing today's glory and leading the future trend, was born, with the trend-setting design, cutting-edge technology and exquisite quality re-branding for the top luxury car market. Defining luxury, Audi has a more design, technology, and more powerful full-LED headlights for this most important flagship model ever, making it the crowning touch of the new Audi A8LW12.
Light Emitting Diode, a digital light-emitting diode from the digital age, is a solid-state semiconductor device that can directly convert electricity into light. LED technology was born in the 1950s, and it was not until the mid-to-late 1990s that high-bright white LEDs for lighting (including broad spectrum) were born.
At the time, LED technology did not have the advantage of being too attractive. Even the LED lights equipped with the PikesPeakquattro concept car in 2003 have only 18 lumens per watt, not even as good as 20 to 25 lumens per watt for ordinary household bulbs at the time, not to mention the popularity of the manufacturers at the time. The xenon headlights are compared to 80 lumens per watt.
The discerning Audi brand has seen the promising future of LED lighting technology. Stephan Berlitz, director of lighting technology, said: LEDs and computer chips are both semiconductor products with very similar characteristics. At the time we had clearly seen that the performance of chip technology would increase by about 30 every two years. LEDs are just beginning to develop and have greater potential. The evolution rate is definitely higher than 30 every two years. It will not take long for us to use LEDs to usher in a new era of lighting. Sure enough, in 2009, LEDs surpassed xenon headlights and reached 100 lumens per watt. By the end of 2010, this figure has risen to more than 150 lumens.
Compared with other lighting technologies, LED technology has fantastic advantages: high efficiency, the spectrum emitted by LED is basically visible light, and the amount of lumens generated per unit of energy consumption is large; long life, LED has theoretically long life The light flux of ordinary LEDs needs to go through 100,000 hours from 100 to 70, which exceeds the normal service life of the car; safe and reliable, the working voltage is between 1.5V and 5V, there is no easy-to-destroy structure such as tungsten wire; It can be flexibly used in small spaces; it is environmentally friendly and contains no toxic heavy metals such as mercury. It has almost no pollution and materials can be recycled.
