Shortly after BMW announced the application of the laser headlights, Audi, which has always been good at "playing lights", could no longer hold back. On February 17, Ulrich Hackenberg, Audi's director of technology research and development, publicly promised that Audi will launch laser headlights faster than BMW.
In this regard, industry analysts believe that BMW and Audi have shown aggressive posture in the development and application of automotive laser headlights, which means that the competition between the two in the future technology field will become increasingly fierce. However, in the face of the approach of laser headlights, is it necessary to be careful about the widely used LED lights?
Competing for the first
BMW officially revealed that it will begin mass production and sales of its self-developed i8 plug-in hybrid vehicle in the fall of 2014. It is interesting to note that the car will be equipped with laser headlights.
In this regard, industry commentators believe that during this period, if Audi does not kill to act as a "roadblocker", BMW's i8 will become the world's first mass-produced model equipped with new laser headlights. According to the reporter, the BMW i8 laser car headlights debuted at the 2011 Frankfurt International Motor Show, and its old rival Audi showed great interest in laser headlights at the same time. At this auto show, Audi released A2. The concept car is also equipped with a rear fog lamp powered by a laser diode.
In the face of the momentum of BMW, the Audi who enjoys the "Master of Lights" must not be outdone. On January 6th, during the International Consumer Electronics Show in Las Vegas, USA, Audi made a high-profile appearance on the Sport Quattro Laserlight concept car, and for the first time demonstrated a dual-lamp set with matrix LEDs and laser headlights. The product is amazing.
According to reports, compared with Audi's previous laser fog lamps, the model is named Matrix's headlights using a total of 50 LED modules, full of technology and more cutting-edge. After showing Audi's latest laser headlight technology, on January 7, Hackenberg said that the 2014 R18 E-tron Quattro Le Mans will be equipped with laser headlights and will be unveiled in the first race in April.
Looking at BMW's upcoming "first" application of laser headlights, Hackenberg publicly said that Audi will be the first to apply laser headlights to its production models, but details such as specific models and time have not been disclosed.
Audi has always been aware of the "intention" of car headlights. In the development of new lighting technology for automobiles, Audi not only pursues artistic sense in design, but also seeks to be the most suitable for car "eyes" from the perspective of safety and convenience. Products, from the initial LED lights to the introduction of OLED light group lighting, to laser rear fog lights, to today's laser headlights, Audi's "lights" have been regarded by the peers as the object of imitation and transcendence, becoming its brand image One of the highlights, Audi has been praised by many media as the "master of the light" in the automotive industry.
In fact, in the development of headlights, as early as 2003, Audi has become a well-known "lighting factory" in the industry. At the Detroit Auto Show that year, Audi released the Pikes Peakquattro concept car, the world's first high-performance LED fog lamp for the first time; in just two years, Audi launched the world's first model with LED daytime running lights ——A8L W12; Today, LED daytime running lights have become the unified design of all luxury car brands. Audi has always been seen as the leader in the new wave of global automotive lighting technology.
More efficient and energy efficient
In fact, it is no longer a new thing for the public to use lasers for lighting. The light show that has been frequently staged around the world has been largely done with laser lighting. The reporter learned that as a light source for laser headlights - laser diodes and light-emitting diodes (LEDs) that we are now more familiar with are almost born in the same period, the use of laser diodes as headlights for automobiles has only been proposed in recent years. Thoughts. Only BMW and Audi brands have officially announced plans to use laser headlights.
According to overseas media, the road to the realization of lasers as car headlights is far more complicated than we think. Since the laser source is not easy to form the sheet-like illumination area required by the headlights of the car, the achievable color is very limited. At the beginning of the research and development, the idea has been questioned. After continuous experiments, BMW and the Sandia National Laboratory of the United States first proposed a "reliable" solution. They combined blue, red, green and yellow light sources to create a common illuminator. A beautiful white light source.
Since it is so hard, why does BMW and Audi still respect this technology? This is mainly because of the many advantages of laser headlights, the most significant of which is more efficient and more energy efficient. The reporter found that the laser headlights not only have the advantages of fast response speed and low brightness attenuation. Compared with the current widely used LED headlights, the size of the laser headlight assembly is smaller, and the length of a single laser diode element has been It can be 10 microns, only one percent of the size of conventional LED components. In this regard, industry insiders explained that this will give car designers more space for front face design.
More importantly, the illumination of the laser headlights is more efficient. It is understood that the luminous efficiency of LED lighting is about 100 lumens / watt, and the laser lighting is about 170 lumens / watt. In addition, in terms of the illumination range, the advantages of the laser headlights are more obvious. It not only achieves flexible illumination, but also directionally illuminates the front, and the illumination distance is twice that of the LED high beam. In terms of energy saving, according to figures released by BMW, the energy consumption of the i8 using laser headlights is only half that of using LED headlights.
The era of laser headlights is coming soon?
â—
As the BMW i8 advertising words say - Now with Laser Headlights (now in the era of laser headlights), with the laser headlights in order to follow up in the application, car headlights will usher in a revolutionary laser era .
At present, although BMW has announced its application plan, it has not confirmed its laser lamp supplier. According to relevant media, Germany Osram Opto Semiconductors has invested heavily in this laser technology and will most likely become the "winner" in the supply of BMW laser light. When asked if the company would provide laser diodes for BMW, Sevugan Nagappan, Osram's infrared and laser product marketing manager, declined to give any information and only said that he is optimistic about the prospects of laser headlights.
However, some insiders hold the opposite opinion. They believe that despite the widespread attention of laser headlights, LED lights are still favored by everyone. Compared with LED lights, laser lights have not yet discovered the "decisive advantage" that can be "anti-goal". From the current market reaction, LED lights have proven to be the best choice for automotive taillights, turn signals and daytime running lights. As prices continue to fall, they believe that LED lights will also become an important source of light for the headlights. The new A8 model released by Audi in September 2013 is the best example. The headlights of this car are made up of new matrix LED lights. A total of 25 high-beam LEDs.
In addition, analysts said that given the excellent performance of LED lights in many aspects, when they can widely adopt laser headlight technology, they have not been able to predict the specific time. But there is no doubt that the Audi Sport Quattro concept car offers a new concept – laser lights and LED lights can also appear in one car at the same time.
