Do not compete with Audi BMW laser, Mercedes Benz why only play LED?

What is the most popular form of headlights now? Many people believe that the answer will be LED lights. Yes, compared with the traditional lamp LED lamp has the advantages of small volume, low power consumption, and higher brightness, longer service life, on the road everywhere LED daytime driving lights visible (especially after it is installed, the light was dazzling) reflects the LED lamp heat.

LED daytime driving lights on the road can be seen everywhere to reflect the current LED car lights

Of course, LED daytime driving lights, although more, but because of the cost of the reasons, LED headlamps have not been able to develop to the level of street lights. And in the LED lamp technology is still in the development stage, has a "lamp factory" said after the launch of Audi A8 full matrix LED headlamps shortly after, in order to continue to maintain its leading position in the lighting technology, R8LMX introduced a more advanced laser headlight. For laser headlight technology, BMW is not far behind, in the I8, also launched a laser headlights, and in 2015 launched a new generation of BMW 7 series of optional laser headlights, we further narrow the distance with laser headlights. Audi and BMW in the fight when the laser headlight technology, the old rival - Mercedes Benz does not seem to be a cold laser headlights, but vowed to be the development of LED headlamps in the end!

Laser headlamps is the best?

LED lamp or laser headlights, from a technical perspective, the laser headlights in the vast majority have the advantages of LED, irradiation distance also has longer (more than 600 meters, the traditional LED is 300 meters), higher brightness, smaller volume, higher energy efficiency, but it is also because the "new", the high cost has become the biggest drawback, laser headlights at the same time, some technical problems are not solved, such as lights, must be able to work within the range of +100 DEG C at -40 DEG C, and to ensure the laser diode can work stably in more than 50 degrees, at present there are still technical problems, so the larger Benz, do not blindly follow the trend, eager to launch laser headlight models, but is more optimistic about the market potential of LED headlamps.

Laser headlights in the majority of the advantages of the LED, the farther the distance, brighter, smaller size, higher energy efficiency.

Mercedes Benz LED headlight Road

Benz LED headlamps road divided into three generations from the first generation to the third generation, we can clearly be seen in the light area control becomes more accurate, while avoiding the oncoming vehicles caused by glare of the premise, as far as possible to improve the irradiation range for the front of the environment, and to increase the number of controllable LED light source thanks to the precise control of the irradiation area, the Benz LED is in the second generation technology has reached 84 of the LED light source (geometry made a new generation E class of multi beam LED headlamps is 84 LED), however, by increasing the number of LED light source to increase the traditional method of light source control precision will be limited to the volume of the headlight.

At present, the use of the second generation LED E headlamps is the most advanced Mercedes Benz headlight Technology

The second generation technology bottleneck gave birth to the third generation, third generation of the Mercedes Benz LED headlight technology led by OSRAM (OSRAM, light source, and the famous manufacturer) and the Association for the promotion of Daimler, Fraunhof applied research (Fraunhofer Europe's largest application of scientific research institutions), Hella (Hella) and Infineon (Infineon) joint development, at present, the sample has been successful through the test. The third generation of LED headlamps headlamps in each module consists of three LED light source, wherein each LED light source is 1024 light controllable (also understood as 1024 pixels as we know, 1024) bright spot can be achieved.

Each of the third generation LED headlamps modules are composed of three LED light source

Each LED light source is controlled by 1024 points

LED light source size is very small

After third generations of technology, based on the existing automatic emergency brake (AEB) and adaptive cruise control (ACC) prior to the camera module for vehicle or pedestrian recognition technology, which was used by mapping, you can control the corresponding spot of LED source on and off, in order to maximize the lighting environment and to minimize the vehicle / pedestrian dazzling.

Mercedes Benz third generation LED headlamps technology will be revolutionary

Everyday driving, not only to see far, but also to see a wide laser headlights although has an absolute advantage in the irradiation distance but in divergent aspects as LED headlamps, and laser headlights to achieve high resolution LED light controlled Benz or very difficult, therefore, can be obtained in irradiation from the premise of good, and can have a wider range of radiation, but also can realize the accurate control of the irradiation region (digital light), it can be said that the technology of the third generation of Benz LED headlamps will be revolutionary. As expected, in spite of the reliability of the experimental stage, Mercedes Benz's third generation LED headlamps technology should be equipped with the next generation of W223 S models on the.
